Abstract: 348,630. Calculating - a p p a r a t u s. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A.- (Assignees of Muller, R. L. ; 14041, Glenwood Avenue, Detroit, Michigan, U.S.A.) Nov. 12, 1929, No. 34524. Convention date, Nov. 23, 1928. [Class 106 (i).] Adding and subtracting apparatus ; operation and item counters.-A machine for use in banks or other business houses for issuing a voucher such as a cheque, a check for supplies or services, &c., and for recording the same on a record sheet comprises a consecutive numbering mechanism, mechanism for performing a number of cycles of operation, and means for advancing the numbering mechanism automatically in a predetermined one of the series of operations. The machine described has a travelling paper carriage and means controlled or actuated thereby in certain columnar positions for operating the numbering mechanism whereby the vouchers are serially numbered or otherwise characterized. The machine is also provided with means for recording the amounts and the date. As shown applied to a Burroughs accounting machine the right-hand key banks are utilized for the amounts and the word " and, " the next banks for the consecutive numbering, and the left-hand banks for the date. The numbering mechanism comprises a plurality of pinions 20, Figs. 3 and 9, mounted on a shaft 21 carried by a frame 22, each pinion being provided with a transfer segment 33 controlled by a detent 62. When the paper carriage has been tabulated to the column chosen for consecutive numbering a roller 40 thereon, Fig. 1, rocks a yoke 42 which through an arm 43 and lever 44 moves rearwardly a link 45. This link is connected to a three-armed lever 48, the forward arm 50 of which is connected to a bellcrank lever 51, 52 co-operating with the arm 54, Figs. 1 and 4, of a yoke member 55. Another arm 57 of the yoke member through a bell crank 59 and link 60 co-operates with an extension 61 of the units detent 62 so that when the link 45 is moved the detent 62 is rocked and the transfer segment freed to impart a step movement to the units pinion. The pinions 20 are associated with the usual type of actuating racks 610 and are adapted to be moved into engagement therewith by imparting a rocking movement to the frame 22 by means of a cam 23 having various surfaces for engagement with pass-by pawls 24, 25 on a yoke member 26 connected to the frame 22 and slidably mounted on a shaft 27 whereby the time of engagement of the pinions with the actuating racks is varied. The keys of the numbering banks are used only when it is desired to set up an initial number on the pinions so that normally the release of the racks must be effected by other means. For this purpose the usual actuator latches 415 are provided with projections 63 engaging the yoke member 55 and are operated to free the racks when the yoke member is operated. On the other hand the usual tail 16 of each latch is omitted in order that the depression of the total key may have no effect on these latches. The lower arm 47 of the three-armed lever 48 is provided with a pawl 71, Fig. 4, yieldingly engaging a pin 70 on a bell-crank lever 28 connected to the slidable yoke member 26 so that when the arm 47 is pulled rearwardly the yoke member is moved to cause the cam member 23 to rock the pinions 20 into engagement with the racks prior to their descent thereby causing the number standing on the pinions to be set on the usual type sectors carried by the racks. The pinions 20 remain in mesh with the racks during the return movement as in a sub-total taking operation. To permit of this movement of the pinions without interfering with their control by the control lever 30, Fig. 4, the arm 47 co-operates with the control lever through a lever 74 carrying a pawl 77, this pawl and an extension of the lever being connected by a spring 79 and engaging abutments on the arm 47. Thus when the link 45 is moved rearwardly the arm 47 merely extends the spring 79, when the lever 30 is moved rearwardly to sub-total position the lever is rocked clockwise and moves the arm 47 and link 45 rearwardly, when the control lever is moved forward to total position the arm 47 will be effective to operate the bell crank 28 unless the carriage roller 40 is engaged by the arm 41 under which conditions the spring 79 will yield and leave the bell crank 28 unaffected. The transfer segments must be restored after each operation but since in the standard machine the restoring bail is inoperative when the machine is set for sub-total taking means must be provided to ensure return of the sectors. This may be done manually or automatically by shifting the carriage to another column position where the arm 41 is free of the roller 40. The operation of writing a cheque and producing a record on the journal sheet as shown in Fig. 11, is as follows. The carriage is moved to the No. 1 column in which position the roller 40 operates the arm 41 and advances the units pinion 20 one step. In this position the date and amounts are entered and the starting bar depressed. This operation prints the date and serial number only on the cheque, the hammers of the amount printing mechanism being blocked and the controls for the totalizer 916 being in a non-add condition. The carriage, by a repeat mechanism, tabulates to No. 2 column where the machine is given a stroke of operation to print the date, number, and amount on the journal sheet. The carriage is then returned automatically to No. 3 column and the platen line-spaced. In this position the machine is operated to print the amount (dollars only) after which the carriage tabulates to No. 4 column. An operation in this column causes the cents amount to be printed and the amount dollars and cents to be accumulated on totalizer 916. After this operation the carriage tabulates back to No. 1 column and the numbering counter advances one unit. To clear the machine after a series of such operations the carriage is moved by hand to the No. 3 column position, a special key is depressed to disable the tabulating mechanism, a special key 80 is depressed to rock the bail 55 and release the latches 415, and the control lever 30 moved forward to total-taking position. By this means when the machine is operated for two cycles the pinions 20 are reset and the transfer segments 33 restored. The totalizer is cleared by the usual total-taking process, the carriage being first moved to No. 4 column position since in No. 3 column position the controls are in a non-add condition. In order to charge the numbering counter with a given number a special key N, Fig. 4, is depressed after the machine has been cleared and before it is returned to the starting position No. 1 column. A heel 94 on the key stem obstructs a pin on the rear arm 96 of the three-armed lever 48 to prevent movement thereof by carriage roller 40 and prevent release of the transfer segment 33. The keys in the numbering section are then depressed, the key in the lowest bank being one less than the number it is desired to enter and the machine operated. The key N is then released to permit the lever 48 to rock to release the latch 62 and cause the transfer segment to add a unit. The special key N when depressed allows the machine to be used for ordinary calculations on the totalizer 916. The stem of the key carries a stud 130 adapted to engage an arm 131 of a V-shaped member whose other arm 132 engages a pin 133 on a bell-crank lever 119, Figs. 1 and 4, which is rocked, when the key is depressed, out of engagement with a spring-controlled pawl 123 permitting the pawl to move out of the path of the usual pass-by pawl 821 on the operating lever 813 and thus prevents the pawls being disabled. In the No. 1 column position the controls are in a non-add condition brought about by a roller 110 on the carriage rocking a yoke 111 connected to a lever 112 having a pin 114 engaging the raised portion 115 of the arm 116 of an irregular shaped member pivoted at 117 and having an arm 118 carrying the bell crank 119. When the irregular shaped member is rocked the spring-controlled pawl 123 is rocked counterclockwise to interfere with the pass-by pawl on the operating lever 813 and prevent its engagement with the studs 961 of the operating lever 913. To ensure that the pinions 20 are in addition condition when being charged the lower end of the stem of the key N has an extension 145 for engaging the pin 114 to hold the lever 112 down to maintain the non-add control mechanism in addition condition. To prevent printing during the charging operation the stem of the key N has a pin 150 engaging the arm 151 of a bell crank whose other arm 153 controls through a plate 155 the blocking of the printing hammers. The machine may be provided with a set of multiple counters of known form mounted on the sleeve that carries the pinions 20. This sleeve is slidable so that when the pinions 20 are in active position the multiple counters are inoperative and vice versa.
