('01. 235—61.6) -This invention pertains to record controlled , amount of record material since at least nine rec chines which simultaneously operate several in- ‘ ord positions must be provided for each column while only one such position is or can be used. dependent counters or accumulators from a plu 5 rality of perforated or otherwise indexed record columns. ‘ perforations. The second mentioned system reduces the 5 amount of record material necessary to obtain ' ’ Heretofore machines of this class have depend ed for their operation upon one of two systems of The ?rst utilizes the digit index 10 system in which each digit has its distinctive in dex position upon ' a record card arranged in mathematical ratio from zero point. w The ?rst mentioned system involves a large machines, or more speci?cally to accounting ma The second nine digits but in order to translate the hole com binat‘ons into one of the nine digits the machine requires a separate translating organization for ' each column or combination of holes, and since 10 a large number 'of columns must be read and translated simultaneously to serve any useful pur system utilizes what has been known as the com pose, the mechanism ls accordingly complicated binational hole code system of perforations, and expensive to manufacture and maintain. wherein arbitrary combinations of holes are made to represent the digits and depend for their anal ysis and translation upon sensing elements and a multiplicity of notched permutation slides, or other equivalent electrical or mechanical analysis 39 and translation devices. When a digit is to be expressed on the com binational hole code card it is, by suitable mech anism in the perforating device, translated from the realm of mathematics'into that of mechanics g5 and expressed in the form of an arbitrary code upon the record card, such code having no mathe matical properties whatever but being arranged In the past, many variatlonshave been devised 15 for carrying out both systems, but all have ‘de pended, either upon the digit index position with its attendant extravagant use of record material, or upon the arbitrary and ?xed combinational code with its complicated and expensive analyzing 20 and translating mechanism. The system forming the subject matter of my invention eliminates the necessity of complicated analyzing and translating mechanism and yet provides means for expressing a number great- :5 er than the number of index positions on the card. The largest number ever to be expressed in a only in accordance with some‘ mechanical con venience. It will therefore be apparent that the 39 second system involves a transmutation into the machine itself of the mechanicsof the digit index card of the ?rst system. The mathematical'control of the combinational single column is pre-analyzed and certain of its component values are assigned to the perforation positions upon the record card. In accounting 30 hole system being located in the machine, inter 35 vening mechanism is necessarily employed for components are chosen for the several perfora tion positions as will singly or in suitable aggre- 35 gation equal any other number up to and in cluding the highest number and these values are analyzing the code perforations in the card re ducing the signals arising therefrom, whether of single or plural nature due to single or plural per forations, into a uniform class of single identify machines where the decimal system is in use the I highest number is nine and such may according ly be used for purposes of illustration. - Such assigned to the several perforation positions. In order to record a digit in any column, the 4!) ing signals and associating any such signals with perforation position thereon corresponding in 40 the proper index point in the mechanism which corresponds to the digit index card of the ?rst value to such digit is perforated if such a per-> foration position exists. If there is no perfora tion position corresponding to such digit, then the digit to be expressed is analyzed into components correspondng to values ‘which are to be found 45 upon the card and such components rather than the whole number itself are expressed by perfo rating the corresponding value positions. Registration of the digit is effected in the class of machines, so that such index points will serve a purpose similar to that served by a single 47, perforation in the digit index card of the ?rst system.‘ ' I‘ ' These index points having mathematical order serve in cooperation with other mechanism to translate the mechanical code back into mathe .'-:) vertical form- giving each separate coded record a value corresponding to‘ the digit which it is in tended to represent. The translation from me-v chanical to'mathematical form having been ac-‘ complishcd. registration of the ‘mathematical 5:, value is effected on some form of indexing devices. machine by direct control in a manner somewhat 50 similar to that employed in the digit index sys tem of perforations when ‘a digit is expressed by a single perforation, and by synthetically com pounding the pre-analyzed record by use of the same registering mechanism when it has been 55 2 2,106,801 necessary or desirable to pre-analyze the digit and express it in the form of components. Whether the digit is expressed by a single or plu rality of perforations, no complicated analyzing or translating mechanism is required in the pres ‘ent machine since all necessary analyzing is done in the process of punching the card and this pre-analysis has in no way destroyed the mathematical properties of the digit even though 10 it has been broken down into constituent parts, and accordingly requires no translation from mechanical to mathematical form. ' My invention comprises, therefore, a new and useful system of record reading and control, 15 which is generically distinct in its operation from anything that has preceded it, and one of its im portant objects is to simplify the record reading and control mechanism. . Another of the more important objects of the invention is to reduce the amount of record ma terial used in record controlled machines. A further object of the invention is to provide ‘means for reading a plurality of index points, such as perforations, in a record card by a single sensing element in combination with a simpli?ed mechanism for registering the values of such index points. » Another object of the invention is to provide means for correctly reading and registering data expressed by a single hole or other index point or by a plurality of holes or index points, when each of such holes or index points has a distinct meaning or value, and in which the plurality of holes, in order to express a digit, does not neces sarily conform to any rigid code. The advantage of this feature of my invention will be further apparent when it is understood that with arbi trary code records in use, the average person han dling such records is unable to read the data rep 40 resented by the perforations since they have no more. If ?ve perforation positions are used the five values are selected in the manner described above so that every digit may be expressed either by the value of a single position or an aggregate value of two or more positions. A detailed de scription therefore need not be given of the man ner of selecting values for a five position card. In order that the invention may be more clear ly described I have chosen the combination, 1, 2, 2, 4 as representing the respective values of 10 the perforation positions in each column of the record in the following more detailed description and it is to be understood that I do not thereby limit my invention to that speci?c combination but that the invention is applicable to all possible combinations of values in groups of four or more. A series of sensing elements is provided to en gage the perforation positions on the card. Each one of these sensing elements in conjunction with the perforations in its respective column of the 20 card controls the movement, and with certain other means also the amount of movement, of an accumulator or a registering member associated with each sensing element. Inasmuch as a sens ing element functions only when a perforation occurs in the position in the column being read at a particular instant, there is consequently no movement of the registering members in such positions as are unperforated. Further objects, advantages, and features of my invention will more fully hereinafter appear taken in connection with the accompanying draw ings, in which: ' Fig. 1 represents the preferred form of perfo— rated record card for controlling the operation of the machine illustrated in Fig. 2. Fig. 2 is a perspective view of the preferred form of an electrically operated machine con trolled by such cards, the electrical connections and other parts of the machine being illustrated 40 mathematical signi?cance, and therefore it has heretofore been the practice to provide elaborate more or less diagrammatically and some of the parts which are not conducive to an understand secondary mechanisms for interpreting and print ing in characters the meaning of the code in some ing of my invention having been omitted entirely. Fig. 3 represents a drum upon which is mount ed the commutator 34, a development of which is shown in Fig. 2. The form of perforated record card employed 45 position on the card adjacent to the combina tional holes for each column. Such mechanism is not required to prepare the cards which the present invention is capable of reading, since with the machine to be described herein will now each hole has its own value distinct from all 50 other holes, and can be so marked upon the card. By a simple primary addition of the holes of any group, the operator is able to read such group. In my system, a value is therefore assigned to 55 each perforation position upon the record card and these values are so selected that the several be described. Referring to Fig. l the values 1, 2, positions when taken singly, or in multiple with assigned values of other positions, will sum up to and include the highest number or value de to sired in the system. This number is preferably nine in accounting machines using the decimal system. It is also desirable though not neces sary that the values assigned to each position on the card should not total or aggregate a num 65 ber greater than the highest number to be ex pressed. Values which are capable of expressing consecutive digits when taken singly or in the aggregate with other values may be such combi nations as 1, 2, 2, 4 or 1, 1, 2, 5 or 1, 1, 3, 4 or 70 1, 2, 3, 3, or 1, 2, 4, 6. It is clear that many groups ~1 of values of four may be selected as shown by the above examples which do not recite all the possible combinations thereof. The system is not restricted to four perfora~ tion positions but will apply to five positions or so 2, 4 are shown as having been assigned to the four value or perforation positions in each column on the card at the points VI, V2, V3 and V4 respectively, and so printed thereon. The card, in addition, may be divided into fields or sections each comprising a plurality of columns of perfo ration positions as indicated at SI, S2, etc. and may be paper or any other suitable insulating material. Throughout it is to be understood that a perforation is only one of the many forms of index points that may be utilized. 60 In order to explain the manner in which the values assigned to the perforation positions are used, let it be assumed that the number 7324 is to be recorded in the first and also in the second ?eld of the card shown in Fig. 1. As previously explained the perforation positions in each col umn are arbitrarily selected as having the values 1, 2, 2, 4 and therefore the thousands digit 7 of the desired number is obtained by selecting values whose sum is '7 which would be the posi tions having values of 4, 2 and 1 in the columns pl. To secure the hundreds digit, positions hav ing a summed value of 3 are selected which would be values 2 and 1 in the columns p2. Since positions having values of 2 and 4 exist in each 2,106,801 of the columns the tens and units digits are secured by a single perforation position in p! and 94 respectively. Since there are two perforation positions in each column whose value is 2 it is apparent that a single number may be recorded in many differ ent‘ways depending @upon which position having a value of 2 is selected to represent a number alone or when summed with other values in the 10 column to secure the desired number. Again in stead of utilizing a perforation having the value 4 to secure the number 4, this number may be ob tained by a sum of the two positions having a value of 2. It is seen therefore that a single num ber may be recorded in a number of different 15 ways merely by selecting different’ combinations of values or value positions and this has been il lustrated in Fig. 1 in which both the first and second ?elds represent the same number'7324 20 yet different perforation positions have been» selected. ' - It will later be shown that the record control-l ling machine illustrated, described and claimed herein is capable of reading either of the com 25 binations shown, or ‘any other combination, with equal facility, and accordingly the system has the advantage of great ?exibility. This advantage is re?ected in savings of both record material and labor. Because of the ?exibility of my system 30 upon which the present application is based, many errors in punching may be corrected, with out in any way affecting the accuracy of the ?nal results.v To recite simple illustrations, if the punch operator while preparing the card strikes 3 cerned. This speci?c embodiment I will now proceed to describe in detail. Referring to Fig. 2.11 quantity of record cards such as those described above and shown in Fig. 1 are placed upright on the platform 2 with the longitudinal rows of perforation positions having a value of 4 at the bottom and are fed, one by one. by any suitable means to the position indi cated by card I for cooperation with sensing elements 20A, 20B, 200 etc., securely held by a 10 suitable supporting bar 20. I have shown the well known reciprocating cross head stripper 3 slid ably mounted in suitable guides and carrying a plate to which projects over the top of the first card slightly less than the thickness of said card 15 for feeding the cards from the platform 2, al though the cards may be fed by hand or any other suitable means. The stripper is driven by a con necting rod 4 eccentrically pivoted to a disk 5, mounted upon a shaft 0 which is so connected by gearing (not shown) to the shaft, it that the stripper, at the proper time, delivers the card to the feed rollers ‘I’ and ‘I’ the latter being driven at. a speed having a ?xed relation to shaft III. A cylindrical feed roller 8 is suitably secured to the shaft Ill and has an outer-surface of some ‘electrical conducting material the purpose of which will be explained later. A gear I I, secured to shaft Ill, meshes with a gear I! loosely mount ed upon a shaft it. This gear Ii has a clutch member “A secured to its face and adapted to be engaged by a cooperating clutch member ll slidable longitudinally upon the shaft it but ro tat‘able with the shaft through a spline IS. _The the 2 key of the punch, when the 6 was intended, he needonly punch a 4 in the same column and the correction is made since the sum of the shaft It is continuously driven by means of the values is 6 the desired number. If a 2 is punched when a 4 was intended, another perforation may be placed in the position of the alternate 2 value of the same column, and the machine will read the combination as the desired 4. It is apparent that many corrections of this character can be is rotated only when the clutching members are engaged as shown in Fig. 2. The well known jaw clutch is used because of its simplicity of made and further ‘illustrations are unnecessary is disengaged from its cooperating member “A motor it through belt "A and pulley I'l'mounted upon the shaft l6 and therefore the shaft i0 illustration but it is clear that practically any known form of clutch is equally adapted and effective for the purpose. The clutch ‘member I4 to indicate the great latitude which the present upon being moved to the left axially upon the invention givesv to the punch operator for cor . shaft l6 by the lever “A pivoted at I33 and recting errors and thereby saving labor and mate having the usual bifurcated arm I3D projecting rial. ' into a circular groove “B in the laterally slid ' The preferred form of the device which is used for perforating the card, being another inven tion, is not shown nor described ‘herein. In its broad aspect the perforated record card, in order that it may properly cooperate withthe machine which it is adapted to control, is ac curately cut to a predetermined size and com ‘ prises a plurality of columns accurately spaced in relation to one another and to the lateral ex~ tremities of the card and each of which columns consists of less than nine perforation positions located at predetermined distances from both ends of the card and from one another and accu able clutch member I‘. The lever ISA is rocked upon its pivot by means of an electromagnet I3 cooperating with an' armature secured to the upper end of lever "A, a spring I30 being pro vided for normally holding the armature with drawn from the electromagnet and the clutch in open or disengaged position. A bar 2. is constructed of insulating material and is held rigidly in position between the side members of the frame of the machine (not shown in the drawings) and is drilled to receive a series of brushes or sensing elements 20A, 2013, "C etc., the center distancesbetween said brushes being equal to the spacing of the ‘columns on the record card. The extremities of the brushes extend rately placed in their respective vertical posi tions, each of said positions when perforated representing a de?nite value; and the values '1 exactly the same distance from the bar 29 and singly or in proper aggregate expressing any vare in a direct line with one another so that they - digit up to and including the digit nine, or stated will register exactly with the longitudinal rows in another way the values being components of of perforation pomtions of the record cards. The the highest number to be expressed by any single bar 20 is set at an angle as shown in Fig. 2 to combination of perforations. The machine oper ating upon and controlled by such a card may obviously assume a variety of forms. Conse quently the machine itself, which is illustrated, described and claimed herein is expressely under stood to be merely the preferred embodiment in sofar as that aspect of my‘: invention is con-; facilitate the passage of the cards between the brushes and the roller 8 with which the brushes 70 are normally in contact without injury 'to either themselves or the cards. The number of brushes corresponds to the number of columns of per foration positions upon the record card. A brush 8A contacts with the surface of the roller 8 and 75 4 2,106,801 is connected to a source of energy such as a bat and which are well understood by those skilled tery 50, the circuit being completed through the in the art, that an explanation of their operation is unnecessary to a complete understanding of the present invention. A commutator or control member 34 is adapted to be connected in series with the electromagnets brushes which are connected to the opposite side of the source through mechanism to be de scribed when a perforation in the card appears opposite said brushes. A card, as it is fed down from the platform 2, passes between the roller 8 and the brushes 20A, 28B, etc., thereby breaking the contact between the brushes or sensing ele 10 ments and the roller 8, which contact is not re material having control means or conducting pieces 35, 36, 31, 38, 38, 40, 4| and 42 imbedded 10 established until the card has passed beyond the therein or mounted thereon in any suitable man roller 8 or unless a perforation exists in a column of the card in which case a brush or sensing element comes into contact with the roller ner. A development of the surface of the com mutator is shown in flat perspective in Fig. 2 to enable its function and operation to be more readily understood, and in its preferred form it 15 is mounted upon or forms the cylindrical surface of a drum, as shown in Fig. 3, which drum is 15 through the perforation. It may be stated at this point that when the roller 8, through a per foration, is engaged by a sensing element a cir cuit is closed and certain operations take place. The downward movement of the card having 20 been arrested by other mechanism, means are provided to operate a registering device or ac cumulator for a period the duration of which is proportional to the predetermined value of that perforation. At the end of such period the move ment of the record card is reestablished by other means to be described. The mechanism for set ting the counter mechanism or accumulators into operation upon the closing of the circuits will now be described. 80 22A, 22B, 22C, 22D, etc., through the perforations in the card and is constructed of non-conducting The conducting wire 2|A connects the brush 20A to an electromagnet 22A which controls a clutch member 24A by means of the pivoted armature 23A. The clutch member 24A, in a well known manner, operatively connects the 35 constantly rotating shaft 33 with the index wheel 25A rotating it an amount dependent upon other mechanism which will be described. The index wheel 25A, which is one form of a differentially adjustable device, is provided with 40 ten index positions marked around its periphery in the usual manner and is freely mounted upon the driving shaft 33, so that it does not turn with the shaft 33 except when selectively con nected thereto by the engagement of the clutch 45 member 24A with one of the ten clutch teeth with which the index wheel is equipped. This mounted upon a shaft 41 driven from shaft l6. It is clear however that the commutator may be a 20 disk or'may take any other suitable form. The conducting pieces or control elements 39, 40, 4| and 42 are of different lengths or dimen sions, the reason for which will be explained later and their lengths are proportional to selected digital values of the various index point positions 25 so that one or more of the elements taken together will produce dimensions or lengths increasing proportionately in units of one and in the same se quence as the assigned values for the perfora tions in the cards. Since in this case the values 30 of the perforations have been selected as 4, 2, 2, end 1 the length or dimension of the conducting piece 39 is four times that of piece 42, and 48 and 4| are twice as long as conducting piece 42. Similarly if the values of the perforations had 35 been taken as l, 1, 2, 5, which is one of the com binations previously pointed out, then contacting piece 39 would be ?ve times as long as the piece 42, 40 would be twice the length of 42, and 4| would be equal in length to 42. These conducting 40 pieces 39, 48, 4| and 42 are furthermore aligned with each other so that a single set of brushes engages the pieces in sequence as the drum ro tates. If the contact pieces were arranged upon a disk then they would be positioned upon a circle or at the same distance from the center of the clutch acts in a manner similar to the clutch |4--|4A, the same being more fully described in the Hollerith Patent 945,236 and is so well under disk. The contacting pieces 35, 36, 31 and 38 are also aligned with each other and are placed paral 50 stood by those skilled in the art that it requires pieces 38, 40, 4| and 42. Pieces 36, 31 and 38 are of equal length and located opposite the insulated spaces between the pieces 39 and 48, 40 and 4|, 4| and 42, whereas the conducting piece 35 is con siderably longer and is located opposite the in sulated space between the adjoining conducting pieces 42 and 39. no detailed explanation here. indows (not shown) may be located over the positions of the counters at which zeros are shown in the draw ings, and through these windows readings may be taken. Although only four of such electromag nets and index wheel units are shown in the drawings it is to be understood that each of the brushes may be connected to a similar elec lel to and in close proximity with the conducting Brushes 45 and 48 are mounted upon an in sulated holder (not shown) so that they contact tromagnet which controls a separate index wheel - with the conducting pieces 39, 40, 4| and 42 and in the same manner as the single unit described above and the wheels grouped into independent counters. It is to be noted however that all the index wheels may be driven from the single shaft 33. In registering devices of this class there are, of course, other supplementary mechanisms re quired, such as means for carrying, or transfer ring from one wheel to the next of higher order, when used for addition, resetting means, means for selectively associating any column of the card with any particular registering member, and mechanism for performing other desirable sec ondary functions. There are however so many well known and satisfactory methods of accom plishing these other results, which I may utilize brushes 43 and 44 are also so mounted upon the 60 same or a similar insulated holder adjacent to brushes 45 and 46 that they contact with conduct ing pieces 35, 36, 31 and 38 as the commutator rotates. The brushes 43 and 44 are connected in series through lead 54 with the electromagnet l3 and therefore these brushes together with the commutatorcontrol the current energizing this electromagnet. The conducting pieces and brushes are so ‘positioned in the manner described that a circuit exists at the commutator between 70 brushes 43 and 44 or between brushes 45 and 48 at practically all times although a momentary de lay in making one circuit after the other is broken is preferable. A brush l8 similar to the sensing element 20A 75 2,106,801 is mounted upon the insulated holder 28 at its end and normally engages the conducting roller 8, when no card is passing over the roller, in the same manner as the sensing element 28A but differing therefrom in being outside of the ?eld containing the columns of perforations posi tions but in the path of the card. This brush is electrically connected by the lead 38 to an electro magnet 29 of a relay mechanism which electro 5 pleted or closed circuit 5|, 3|, electromagnet 28, 38, I9, 8, 8A, 53 and» power source 58, which car ries the necessary current to energize the electro magnet 28 and hold its armature 28 out of con tact with point 32 as previously described. When the card comes between the roller 8 and element l8 this-circuit is broken and the electromagnet 28 is no longer energized to hold armature 28 thus enabling the spring 28A to bias the armature into contact with point 32 thereby closing the 10 magnet has an armature 28 having a spring 28A which normally holds the armature in contact with the contact point 32. The circuit between circuit through the annature and the commuta tor brush 48 but the circuit is broken by the in the brushes 45 and 48 of the commutator 34 to the culated commutator between brushes 48 and 45. source of electrical energy 58 is completed through ‘ The card continues its downward movement between the rollers 8, 8' until the sensing ele 15 15 the armature 28 when in contact with the point 32. ' ments 28A, 203 etc. are over the first or lower A manually operated switch 3| controls the row of perforation positions V4 of the card, the commutator having rotated until at this instant motor and all other circuits of the machine. The operation of the apparatus will now be the brushes 43, 44, 45 and 48 are in position 34A 20 described. A quantity of cards having been where brushes 43, 44 have just broken contact properly placed on ‘plate 2, with any suitable with the conducting piece 35 and the brushes 45, means for pressing them forward against the 48 have just made contact with conducting piece stripper 3, the switch 3| is closed as shown in Fig. 2 which closes the circuit 5|, 3|, l8 and 52 back to the source of energy 58 and motor I8 is started. The motor drives shaft iii to which is 39. At this instant certain actions take place as follows; ?rst the circuit to the electromagnet I3 is broken due to the fact that the brushes 43, 44 are no longer in contact with piece 35 thus re suitably connected the commutator shaft 41, the driving shaft 33 for the registering wheels, the leasing the armature |3A and enabling the spring stripper shaft 8, and other parts as before de scribed. The switch 3| also establishes a branch circuit through 53 to contact 8A, the outer con so that the feed rollers stop their rotation and ducting surface of feed roller 8, brush I8, lead 38, control relay 28 and thence to 3| and 5| back |3C to disengage the clutch‘ member l4 and MA the card remains stationary with the sensing ele 30 ments on the perforation positions V4; second, if there are any perforations in the card in the positions V4, the correspondingsensing elements to the source of energy 58. ‘The closing of this circuit energizes the relay magnet 29 which at tracts and holds its armature 28 away from the pass through these perforations and contact with armature 28 and brush 48 also includes the coun continues its rotation uniformly and the card being stationary with such sensing elements in contact with roller 8 where perforations exist and the circuit established through brushes 45 and 48 and conducting piece 39, the electromag the conducting surface of roller 8 so that the brushes 45 and 48 making contact with conduct contact point 32 which keeps the circuit open ing piece 38 establish these circuits including through 21, 3| and 5| from the source 58 to the such sensing elements energizing the respective commutator brush 48 which is therefore disabled vcounter magnets of these circuits, and throwing the respective counter clutches into engagement 40 from serving its normal function as a return conductor when in contact with the conducting with rotating shaft 33 and rotating the index pieces 39, 48, 4| and 42. The circuit through the or accumulator wheels. Now the commutator ter magnets 22A, 22B, 22C and 22D etc., and ac cordingly such counter controlling electromag nets are not energized as long as the electromag net 28 is energized and holding its armature 28 from contact with the ‘point 32. In the relative position of the parts as shown in Fig. 2 a completed current carrying circuit ex ists from the power source 58, through 53, 55, electrcmagnet I3, 54, 43, 35, 44, 21, 3| and back to 50 so that the electromagnet I3 is energized to hold the clutch member M, Na in engagement to enable the driving of the rollers 8, 8', ‘I and 1' from shaft l8. When a card is fed downward by the crosshead or stripper 3 between the ro tating rollers ‘I, 1', the latter continue the card's downward movement until it reaches the rollers 60 8, 8', as shown in Fig. :2. In this position the commutator, which‘ rotates continuously in ?xed relation-with the crosshead and its associated mechanism, is in the position shown in Fig. 2. Continued movement of the rollers '| and '|' 05 feeds the cards between the rollers 8 and 8' and between the roller 8 and the sensing members 28A, 281?- etc. and also between roller 8 and brush member -|9 the latter breaking the circuits through the other sensing members 28A, 283 net 22A etc. are energized as long as the brushes _ 45 and 48 are in contact with piece 38. It is for this reason that piece 39 has a length of four units so that this circuit exists for four units of time and electromagnets 22A etc. are‘, energized for four units of time enabling the index wheel clutches to be operatively connected to shaft 33 , for four units of a complete revolution of shaft 33. The index or accumulator wheels have therefore registered a four. It is clear that if no perforations exist in position V4 for the sensing element 20A etc. no circuit is completed, no in dex wheel is connected to shaft 33, and no regis terlng of the index wheels takes place. When the commutator has rotated so that the brushes 45 and 48 engage the same at position 343, shown in Fig. 2, said brushes are no longer in contact with conducting piece‘ 38,- the circuit to all the sensing elements is broken and therefore the respective index wheel clutches are disengaged as will ~be understood. At the same moment that this circuit is broken the conducting piece 38 comes into contact with brushes 43 and 44 com 70 etc. However it should be noted that the cir cuits through 28A, 283, etc. are open circuits pleting this circuit so that electromagnet I3 is because of the break between brushes 45, 46 so ' again energized throwing clutch member I4 into that severing the circuit at 28A, 283 etc. has no engagement with the member MA with a result effect .with respect to these circuits. ’ Brush that a further feeding movement is imparted to the card until the perforation position V3 of the 75 member IS on the other hand is a part of a com 6 2,106,801 card is directly under the sensing elements 20A, 203, etc. At this instant the brushes 4!, 44, 45 feed clutch members i4-l4A to drive the feed. mechanism continuously during such contact. and 46 are in engagement with the commutator at the position 340 and certain actions take place similar to the actions occurring when the sensing elements 20A, 203 etc. were over the perforation position V4 of the card. There is this difference however in the two actions; the conducting piece 10 15 20 25 30 The length of contact element 35 is such as will enable the card feed mechanism to eject the card just read and bring a new card into the position shown in Fig. 2. A complete cycle of operations, therefore, has transpired and is repeated when a second card is fed down from platform 2 by the 40 being only two units long, the index wheel‘ crosshead stripper 3 after which the machine is clutches are in operative relation only two units ready to repeat the cycle of operations described, of time, or for two units of revolution of shaft of properly reading and registering a single or a 31 and therefore two units on the index or ac plurality of perforations upon the next record cumulator wheels are registered, provided, of card. course, that perforations in the V3 perforation Thus it will be seen, among other things, that position of the columns corresponding to said there is provided means adapted to selectively im wheels occur. part variable movements to the registering mem The same actions occur for the V2 position and bers to register the values of the perforations lo the VI position and a detailed description there cated in the positions V4, V3, V2 and Vi respec of is not necessary although it is to be noted that tively; that all of the values of the perforations conducting element 42 of the commutator is in any one of such positions, that is a single value only one unit long, and therefore in position VI correspondingly located in all of the columns, are the index wheels are rotated but one unit of a simultaneously registered on the registering complete revolution and the wheels register only mechanism; that there is provided means con one unit for perforations in the VI position. trolled by the perforated spaces in any column It follows that there is provided not only cer- . for successively registering the values thereof on tain instrumentalities for giving a predetermined the registering mechanism during a single adding value to each perforated position V4, V3, V2 and cycle; that there is provided a plurality of reg VI but also means controlled by the perforations istering members, electrical means for sensing the in each column for summing the values of the perforations in the card, and a single electro perforations therein. In other words means are magnet for each member cooperating with the provided for adjusting the registering wheels to sensing means to control the adjustment of said any desired position during a single cycle of op members; and that there is provided means erations, said means comprising means controlled adapted to selectively arrest the movement of any by the pre-analyzed record card for imparting or of the registering members and holding the same distributing either a single impulse or an aggre at rest for periods proportional to the assigned gation of separate impulses of variable-or prede termined durations to any of said wheels during said cycle, the durations being proportional to the assigned values of the perforated positions of the 40 card orI proportional to the selected relative lengths of the commutator segments 39, 40, 4i and 42 or the relative lengths of the spaces be tween the segments 35, 38, 31 and SI. It is apparent from the foregoing that when tions on the record card. The sectors therefore 40 deliver electrical impulses or provide an electri cal potential upon the roll 8 of predetermined duration and any electrical means which per forms this function is contemplated herein, as well as any mechanical means which provides a may be utilized for other purposes. This giving to the perforations a positive value corresponding to the assigned value constitutes one of the more im portant features of my invention. When the card has passed completely by the sensing elements, the element l9 again comes into contact with the conducting surface of roll I re— establishing this circuit so that relay 2! is ener 70 gized and all circuits through its armature 28 are broken. In the further revolution of commutator l4, conducting element 35 is brought into contact with brushes 4! and 44, thus energizing the elec tromagnet I3 and causing the engagement of card 30 4i and 42 on the commutator 34 are made to mechanical impulse of predetermined extent or responding to the assigned value, and while the embodiment of my invention illustrated herein shows how the values are utilized in connection with registering mechanism it is obvious that they‘ 25 correspond with the values of the reading posi card the value of that perforation is registered upon the index or accumulator wheel correspond ing to that column; and it does not matter how many perforations appear in one column since the mechanism functions the same for each perfora tion in the column and the index wheel is fur ther rotated an amount depending upon the value of that perforation. It will also be apparent from the foregoing that, in combination with the type vided, common to all of the columns of the card, for giving to the perforations a positive value cor 20 values of the unperforated portions of the card. The lengths of the conducting sectors 38, 40, ever a perforations appears in any column of the 55 of card illustrated and described, means are pro 10 duration since it is the impulse, irrespective of how it is generated or produced, which is utilized and contemplated by the invention. Again other means could be employed for delivering current to roll 8 without changing the operation of the machine. I have constructed the commutator as described to provide means for breaking the current at the commutator rather than at the card where an arc is undesirable. The brushes held by the insulating bar 20 are made up by grouping a multiplicity of small wires and as preferably arranged the lower portion of the brush is still in contact with B through the upper portion of the perforation for sufficient time after 60 the card has begun to move downward to permit 38, 40, 4| or 42 to de?nitely leave the brushes 45 and 46 before contact between the sensing members 20 and roll 8 is broken thus causing the current to break at the commutator. It will be readily understood that other values than those assigned to the card may be read with equal facility by changing the relative dis tances between 35, 36, 31 and 38 and changing the lengths of the contact elements 39, 40, 4| and 70 42 to correspond to the values assigned to the card, or by otherwise providing means for hold ing the card in reading position for each value position a sufficient length of time to enable the counter driving shaft 33 to move the registering 75 7 2,106,801 members at least the'numb'er of index positions which correspond to the values being read. Dur ing such rest of the card there is delivered in any suitable manner an electrical impulse of su?icient duration through the perforation spaces, as will control the engagement of the reg istering members with the driving shaft 33 for a time corresponding to the values of the posi tion being read. The commutator in conjunction with the source of electrical ‘potential applied tion as each perforation position of the column is aligned with the sensing member, an accumu lator wheel, and an electric circuit including means for controlling the accumulator wheel and controlled by a sensing member and one or more Cl perforations in the column of the card for regis tering upon the accumulator wheel a value pro‘ portional to the duration of current which corre sponds to the assigned value of each perforation. 3. A record controlled machine utilizing a per _ forated card having a plurality of columns each thereto is a generator of electrical impulses.

While I have illustrated and described herein and one or more perforations in the column, feed ing means for the card, a clutch controlling the feeding means, a commutator for disengaging the feeding means clutch so that the card is arrested the preferred embodiment of my invention it is to be expressly understood that I do not limit -myself thereto as many changes may readily be made in points of detail and other embodiments resorted to without deviating from the true spirit and scope of my invention. It is also to be under 30 stood that while the invention is particularly‘ adapted to recording devices it is obvious that it is capable of being used‘in connection with print ing and other kindred devices and accordingly . extends to such devices. However, in order that 35 the record cards illustrated and described herein may properly function in the machines which they are adapted to control, it is essential that they be accurately cut to predetermined size, that the columns thereof be accurately spaced in re 40 lation to one another and to the lateral extremi ties of the card, and that the perforations there of be accurately placed in their respective verti cal positions.
