The segments are spaced to correspond to the nine stepping positions of the related cams 304 with a segment 325 for each of the positions to which the device is stepped. These emitters are illustrated diagrammatically in the circuit dia gram (Fig. 14a). In the circuit diagram of the parent application Serial No. 433,178 (now Patent 2,375,275) the contact blades 3I2 and common 15 bars 3I4 are represented in a diagrammatic man ner to represent a grid structure and the man ner in which such grid structure controls calcu usual hopper to the card sensing brushes |2I, and that this period of time is constant and of such duration that the contacts 29 are closed and in turn relay MRI is energized for a period ade quate to accomplish the several functions con trolled by the contacts of the relay as will be pointed out. Magnet MRI closes its contacts MRIa which complete a circuit from line 330, contacts MRIa, two magnets 342 in parallel, to line 33|. The magnets 342 are the reset magnets of a well known form of stepping relay switch. Their energization at this time serves to insure starting of the stepping switches from home po sition. These stepping switches are diagram matically shown in Fig. 14h where their stepping magnets are designated as SRI and SR2. En ergization of magnets SRI and SR2 will directly step the contact arms upon energization of the lating operation of the machine is specifically set magnets against spring action, and the arms will forth. 20 be held in advanced position by the usual hold Briefly reviewing the positioning of slides 308, ing pawls which are released for restoration it is noted that there are eight slides and that through magnets 342. cams 304 make nine steps during a complete rev Restoration of storage units-_When relay olution. For each step of cams 304, except the magnet MRI is energized, a circuit is completed last or ninth step, a slide 308 is moved from the position of Fig. l1 or Fig. 2 to the position of Fig. 8 and then to the position of Fig. 9. While slides 308 are in the position of Fig. 9, their con tact elements 3|2 are set by bails 3l5. In the complete machine the record card is 30 automatically advanced step by step to present the card columns to the row of brushes |2I (Fig. 14a) one yat a time. For purposes of simpliñca tion in the present case, it will be assumed that the columns are manually presented in succes sion, .beginning with column I of the card of Fig. from line 330 (Fig. 14a) , wire 341, the four lower contacts MRIoZ now closed due to energization of MRI, cam shaft contacts 32| of the storage units which are closed if the units are not in their home position (see also Fig. 2), thence through clutch magnets 294 to line 33 I.

Thus, the magnet 234 of the ñrst storage unit is energized and this unit will move from its home position to #l position (see Fig. 9), and during such movement the cam shaft contacts will shift to cause closure of contacts 32| and opening of contacts 322 for this unit, and relay magnet R32 will be deenergized as explained. The time re quired for operation of the card feeding mecha nism and related devices is such that the storage unit is restored and its first columnar1 position set up as in Fig. 9 before the digit magnet 3 I9 is energized in response to the sensing of a per foration. In other Words, the ñrst card column is not presented to the sensing brushes until relay MRI has ñrst been energized and deener gized and relay R32 thereafter energized and deenergized.

Shift to control storage unit #2r-_As a prelim inary to the operation of the machine, it is deter mined hovv many orders in each storage unit are 10 to be used, and this is generally in accordance with the columnar capacity of related card fields. Thus, since the first card field (Fig. 13) is of four column capacity and the data therein is to go into unit l, the brush socket d8 (Fig. 14a) Wired to the fourth segment 325 of the emitter of unit 1 is connected by a plug connection 363 to the I socket of a stepping switch SRI (Fig. 14h). Likewise, since the second and third card fields are also of four column capacity, their fourth emitter sockets di) and dlíl are connected to the second and third sockets bl and cl through con nections 37| and 314 respectively.

The circuit through the storage unit #1, the socket d8 associated with the fourth segment of the emitter unit of the unit fourth position, plug connection 363, plug socket #2 is traceable as follows: from line 330, wire 358, a1 (Fig. 14h) , stepping relay vcontrolled by mag net SRI, the wipers of this relay to the common 50 contacts R52a. when they close, wire 362, emitter brush 323 of unit #2 to the fourth plug socket segment, wire 364, contacts 369 associated with d9, plug connection 31| to socket b1, segment and the relay controlled by magnet SRI, thence common of uppermost emitter SRI, wire 364 to through the stepping relay magnets SRI and SR2, left hand of the lower stepping relays SRI, to in parallel to line 33|.

Thus, relay magnets R21 and R34 are accordingly energized when energized after the initial circuit is broken, due storage unit #2 is in its fourth column entry re to shifting of the relay wipers. ceiving position and when contacts R52a clos'e. Recapitulating, the fourth column of the card A further parallel circuit extends from wire 364, is presented to the brushes I2I and a circuit is completed therethrough to energize the 4 sole noids 3I9 to set up a 4 in storage unit #1. After this is done and while the fourth card column is 65 through contacts 369, stepping relay magnets SRI and SR2 to line 33|. 'I’his has the effect, as still in sensing position, relay R52 is energized (assumed to be manual for present purposes) to complete the circuits traced, to energize relays before, of advancing stepping relays SRI and SR2 together to their third position. The card is advanced to present its ninth col umn to the sensing brushes |2I, and the storage R33 and R25 and the stepping switch magnets SRI and SR2. Relays R33 and R25 will imme diately set up holding circuits as traced, so that as magnet SRI operates to close contacts 310 and advance the switch arms upon energization of unit #3 is prepared to receive entries under con trol of the third neld of the card (Fig. 13). This preparation is the same as that for storage unit #2 in that magnet 294 of unit #3 receives an impulse to bring its first column into receiving 2,405,287 ll position through a circuit traceable from line contacts R331; now closed, R29c, cable 355, contacts 322 of unit #3 to #3 magnet 294, and thence to line 33|. This results in the opening of contacts 322 and closing of contacts 32| so that subsequent ener gization of magnet 294 of unit #3 is through the circuit from line 333, wire 358, contacts R52a, contacts R290., upper contacts MRld, contacts 32|, #3 magnet 2.94 to line 33|. This energiza l2 section of stepping relay SR2, its plug socket d4, plug connection 31S to plug socket e5, relay magnet R39, wire 353 to line 33|. At the same time, of course, the magnets SRI and SR2 are also energized so that both stepping relays ad vance another step to bring their wipers in con tact with the segments in their ñfth positions. Relay magnet R3| closes its contacts R3|b to complete the circuit through cable 361 (Fig. 41d) so that magnet 294 of storage unit #4 will be tion takes place, of course, each time a column of the card is sensed. continuously energized as already explained to ad It may be pointed out that in connection with storage unit #2 this unit is also advanced to its this point in the operation of the machine all four storage units are in their home positions with each containing a setting representing the amounts perforated in the four ñelds of the record card (Fig. 13). Relay R33 serves to initiate operations of read ing out the values entered in the storage devices and its energization is a signal that entries from the card have been completed. Since the reading out operations are not part of the prescrit inven~ home position in a similar manner to that in which unit #l was previously returned to home position, This ís eifected by holding magnet 294 continuously energized through a circuit trace able from line 333, contacts MRlc, wire 349, con tacts R211), cable 331, upper contacts MRI d (sec- < ond from the top), contacts 32| of unit #2, the 2 magnet 234 to line 33|. When this unit reaches home position, shifting of contacts 32| and 322 breaks the circuit. Reading the third amount Sensing of the 10th, 11th and 12th columns of the card and setting of the amount 9012 in unit #3 takes place in the now familiar manner` and, when this unit is stepped to its fourth column 30 the position, number inasmuch is sensedasthe thisfollowing is a 4 column circuitñeld, is com' pleted: from line 33B, wire 35S, contacts R520.. wire 352, brush 323 of unit #3 in the fourth posi« tion, to the plug socket dlll, plug connection 314 vance this unit to its home position, so that at tion, the same are not shown or described herein. Another card may now be sensed and its data entered into the storage devices as before. If this card has the same' number of columns allo cated to each field, the connections 333, 31|, 314 and 311 will remain the same. If, however, for example, the first field contained only two columns of digits, connection 353 would- be made to the socket of the commutator of unit l (Fig. 14a) so that, following the sensing of the second card column, unit #2 is stepped to its first entry receiv ing position.. Unit #l will, however, contain entry in its third and fourth positions from the previ ous card and it is for this reason that unit #l to plug socket o1, thence through wire 354 to the (and other units) are stepped to home position two lower commutatore of stepping relay SR! and upon completion of entries therein. for in doing thence in parallel to plug sockets c| and m, plug so any previous settings in higher orders than connections 315 and 316, respectively, to plug sockets c2 and u2 to energize relay magnets R29 40 used for the current card will. be reset and the unit will contain only desired. data. and R35 in parallel, the circuit being completed The initial resetting of all units at the com~ through wire 353 to line 33|. mencement of operations is a precautionary As before, the stepping magnets SRI and SR?. measure to insure that no settings have remained are energized along with the relay magnets R23 in the units from some prior operation as where and R35. Energization of magnet R35 causes its contacts R35a to complete the now familiar cir cuit through cable 355 and contacts 322 of unit #4 to energize the related magnet 294 and ad~ vance it the one step into position to receive the entry from column i3 of the card (Fig. 13). At the same time closure of contacts R291; also com pletes a circuit parallel to those already traced for the storage units #l and #2 through cable 361, and upper contacts MRld, contacts 32| of unit #3 to continuously energize magnet 294 of storage unit #3' until the latter has advanced to its home position. Contacts R29a incidently open to prevent any impulses being routed to the other storage unit clutch magnets from this source. Reading the fourth amount The data from the fourth field of the card (columns 13 to 18) now is entered column by column into storage unit #4 in the now familiar manner. Since this is a 6 column field, entry progresses until the brush 323 of unit #4 has advanced to the 6th position. In such position a circuit is traceable from line 330, wire 358, conm tacts R52a, wire 362, brush 323 of unit #4 to the in such prior operation entries were made in four .units and only three are now to receive new ein tries. In such case there would be four entries to be read out after the card has been sensed. when only three are desired. While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification. it will be understood that various omissions and substitutions 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 parting from the spirit of the invention.
