Oldenboom, Endicott, N. Y., assigner to International Business Machines Corporation, New York, N. Y., a corporation of New York Application January 16, 1935, Serial No. 1,991 4 Claims. (Cl. 164-112) This invention relates to certain new and useful improvements in perforating machines. More particularly, this invention relates to per forating machines such as used in connection Ul with perforation of cards used in the well known Hollerith system of accounting in which perfo rations are made on a card at selected index points, which are differentially located with re spect to each other. Such a punch is shown in the Hollerith patent No. 682,197 issued September 10, 1901, which is designed to perforate the well known Hollerith card. In a punch of this type, each time a column is perforated the card carri age automatically steps ahead to present the next column for perforation. This method of opera tion is satisfactory whenever a regular prear ranged form of perforating is to be used, particu larly wherein all the information is punched on the card at one punching operation, which meth od largely predominates. There are however many instances of statistical analysis where in~ formation is acquired from time to time which must be perforated on cards which have already been perforated in many columns. An example l of this type of analysis is used in hospitals and sanitariums where case histories of the individual patients are kept on cards. Codes are used for the variousv diseases and inñrmíties that are en countered and these codes are punched on the in 30 dividual patient’s card in accordance with what ever malady the patient is afflicted with. The columns to be perforated thereforev may vary considerably with each succeeding card, there being many columns in each card in which perforations are entirely omitted in which no two succeeding cards will require the same columns to be passed with no perforations. It is essential therefore that the machine for perforating these cards must be flexible for quickly locating the card 40 at' the proper column with ease and accuracy to be sure that when located the index points on the card will be in proper alignment with the punches. It is an object of this invention to provide a per 45 forating device in which the object to be perfo rated may be moved quickly to any position to be perforated. Another object is to provide mechanism for locking the card into positive position in align 50 ment with the punches. y A still further object is to provide locking mech anism for locking the machine against >punching until the card is positively located for the punch ing operation. Still another object is to provide Ya locking mechanism to render the perforating mechanism inoperative» while the card carriage :is being moved. Various other objects and advantages of my in 60 vention will be obvious from the following particu 55 lar description of one form of mechanism em bodying the invention or from an inspection of the accompanying drawings; and the invention also constitutes certain new and novel features of the construction and combination of parts herein after set forth and claimed. In the drawings: _ Fig. 1 is a plan view of the machine. ‘ Fig. 2 is a partial longitudinal section showing 10 the punching and locating mechanism. Fig. 3 is an enlarged detailed cross section show ing the locating and locking mechanism. A base Iû is provided with a trough-like run way II of proper width to receive a card which may be moved longitudinally of the base. A slot I2 is provided in the base which runs its entire length and in which runs the card carrier. The card carrier comprises two end pieces I3 and I4 which are connected to a bar I5. The distance between the end pieces is substantially the length 20 of the card to be perforated. A small spring pressed member I6 is provided on the end-piece I3 to hold the card snugly against the end-piece I4 and thus hold it in fixed position. The bar I5 is provided with rollers I‘I running on tracks I3 25 which are cut into the bar I9 fixed to the base of the machine. The end-piece I3 is connected to the bar I5 by a member 20 on which is mounted a handle 2| for the purpose of manually sliding the card carrier back and forth by virtue of the 30 rollers I'I and the roller 22 which rests on the base of the machine. The handle 2l is provided with a plunger 23 which is biased upwardly by a spring 24. The lower end of the plunger terminates ad jacent the bottom of the slot I2 and is adapted to 35 cooperate with apertures 25 located in spaced re lation to each other along the bottom of the slot I2. Adjacent these apertures on the underside of the bed plate opposite to the plunger 23 is a bail 26 extending longitudinally of the machine in line 40 with the centers of all the apertures and for a distance covering the length of travel of the end plece I3. A This bail is supported at each end of an arm 21 ñxed to a shaft 28 which is journaled in the sup 45 porting webs 29 of the base ID. Fixed to one end of the shaft 23 is an arm 30 which is biased in a counterclockwise direction as shown in Fig. 3 by a spring 3|. The upper end of said arm is bifur cated and engages a pin 32 (Fig. 2) ñxed to a comb 50 33 having slotted ends engaging a T-shaped mem ber 34 mounted on the side frame of the key sup porting structure 3,5 so that comb 33 is slidable back and forth transversely of the perforating de Vice. 55 The perforator is provided with the usual well known arrangement of punching mechanism such as shown in the previously mentioned Hollerith Patent No. 682,197 in which a series of punches 36 are slidably mounted in a frame member 31 and 60 2 2,107,160 are biased upwardly by springs 38 so that their upper ends abut a lever 39 which is fulcrumed at Aone end against an adjustable fulcrum 40. The and the end of the plunger 23 strikes the bail 26 deiiecting it downwardly and turning the shaft 28 in a clockwise direction, thereby turning the arm 39 clockwise about its'supporting axis and mov levers 39 are held from side sway by a slotted plate in which each lever is positioned by aslot. ing the comb 33 to the right so that the teeth 44v . The levers are of diiîerent length and terminate Y , now lie under the slots 45 so that the operator within the key supporting structure 35 in stag- ’ may select the key he desires. If for example the Y Y gered relationship.

The levers 39are held up The punches 36 are located transversely of the ` wardly by virtue of the springs 38. Y Y , machine and parallel to the card columns, there Directly beneath the punches 36 and spaced being one punch for each index point positionY in therefrom a distance equal to the thickness of the column and spaced apart in accordance with 15 the material to be perforated is a die plate 43 provided with a die to receive each punch. The comb 33 is provided with a seriesV of up wardly' extending teeth 44 which terminate `di Y rectly underneath the levers 39 andthe width of each tooth is substantially one-half the width of each lever. The levers 39 are provided with slots 45 extending substantially one-half the width of the levers and adjacent the ends of the teeth 44. In the normal position of the comb 33, as viewed in Fig. 3, the teeth `44 are positioned under the the spacing of the index point positions. The apertures 25 are spaced longitudinally ¿of the card and correspond to the columns inthe card. They are spaced apart in accordancevwith 20 the spacing of the columns. It is therefore ’im possible to perforate the card unless theplunger 23 enters one of these apertures to remove the comb 33 from blocking position and by virtue of this operation locking the carriage in position whereby a column of ythe card will be located cor- n rectly under the row of punches. ~ solid portion o‘f the levers 39 to lock them up so Y Ythat the keys 42 cannot be depressed. When the comb is moved to the right the teeth are then located underneath the slots 45 which clear the teeth so as’to permit the levers 39A to be de-V pressed downwardly by their respective keys thereby thrustingV the corresponding punch 36 into its die to eii‘ect a perforating operation. Attached tothe bar I9 Vare brackets 46 which support an index holder" adapted to receive an enlarged reproduction of a portion of the card to be perforated. The reproduction is substantially 40 twice the size of the card to be perforated to fa cilitate the quick location of the card into the selected position. While Vthe fundamentalv novel features of the invention as applied to a single modification has been shown and described and pointed out it Vwill be understood that various omissions and sub~ stitutions and changes in the form and details ' of the device illustrated and in its operation may be made by those skilled in the art without de-V parting from the spirit of the invention.
