Patent GB-362857-A (GB)
Abstract: 362,857. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A.-(Assignees of Brand, S. ; 144, Forrer Boulevard, Oakwood Village, Dayton, Ohio, U.S.A.) Sept. 8, 1930, No. 26732. Convention date, Sept. 9, 1929. [Class 106 (i).] Machines with several item-value totalizers.-In a cash register, accounting or similar machine having a plurality of totalizers on a common axis, means are provided for transferring a total from any one totalizer to another located on the same axis, in one continuous operation of the machine. The invention is described as applied to a machine of the Shipley type forming the subject-matter of Specifications 8119/15, 176,781, 191,346, 191,350, 191,351, 192,083, 194,291, 215,010, 296,002, [all in Class 106 (i), Calculating &c.], &c. The machine includes a single line of totalizers 75, Fig. 23, selected by a bank of transaction keys 30, 31, Fig. 24. The totalizers corresponding to the " Cash and " Charge'' keys 30, when reset, automatically transfer their totals into a " Grand Total " totalizer situated in the zero position in the totalizer line. The remaining totalizers corresponding to the keys 31 operate independently in the usual manner. In a total or sub-total taking operation the desired totalizer is selected by depression of the corresponding key after the adjustment of the total control lever 32 to its first position for the keys 30 or to its second position for the keys 31. A total transfer operation resembles a subtotal taking operation in that the totalizer line is rocked into engagement with the actuators 50, Fig. 23, during the first cycle and rocked out of engagement at the end of the second cycle, by means of the usual mechanism. Flexible means are provided in the totalizer selecting and engaging mechanisms to enable auxiliary mechanism to operate, after the actuators have come to rest under the control of the pinions of the selected totalizer, partially to disengage the totalizer, return the totalizer line to zero position and engage the " Grand Total" totalizer with the actuators, so that upon the return of the actuators the total taken from the selected totalizer is added into the " Grand Total " totalizer. Partial disengagement of totalizers. The selected totalizer is engaged with the actuator during the first cycle of operation by a downward movement of the usual totalizer engaging link 258, Figs. 17, 21, and 23, that is connected to the totalizer supporting shaft 219 through a link 251 and spiral spring 257 to cause the usual roller 245 to move to the lower end of the cam slot 250. Immediately after the actuators have come to rest under the control of the totalizer pinions, a slotted link 393 is moved downwardlv bv cams 394 on the main shaft to rock an arm 256 fast on the totalizer supporting shaft, whereby the tension of the spring 257 is increased and the roller 245 is moved to the position shown in Fig. 21 to raise the totalizer pinions out of mesh with the actuators. The totalizer line is then shifted to its zero position and the slotted link 393 is moved upwardly to allow the pinions of the " Grand Total " totalizer to engage the actuators, under the influence of the spiral spring 257, just prior to the return movement of the actuators. Mechanism for positioning the " Grand Total " totalizer. The totalizer line 75 is axially adjustable by means of the usual cam 224, Fig. 23, connected to the indicator sector 138, Figs. 13 and 23, through link 239, shaft 92 and spring 236. In a total transfer operation, immediately after the partial disengagement of the totalizer, the shaft 92 is rocked against the action of the spring 236 to return the totalizer line to zero position, in which position it is held, after the engagement of the "Grand Total" totalizer with the actuators, by means of one of the usual recesses in the cam 224. The shaft 92 is rocked by cams 404 acting through bell crank 410 and link 401 to cause the outer end of an arm 400 to abut a roller 403 on an arm 234 fast with the shaft. Normally, a stud 414 on the bell crank 410 idly traverses an arcuate slot 415 in the link 401, but in a total transfer operation, the link is rocked to the left to fit an offset 416 over the stud. The means for rocking the link 401 comprise a tappet 423 that is rocked towards the left in two stages by a bail 370 which derives its movement from the usual shaft rocked by the total taking mechanism. In a total transfer operation, the total control lever acting through a lever 419 shifts the tappet upwards, so that during the second stage of movement, the latter abuts a projection 428 on an arm 429 and swings the link 401 to the left. Interlocks. Means are provided to prevent the adjustment of the total control lever 32 after the depression of a transaction key 30 or 31. Upon the depression of a key 31 the zero stop pawl 108, Fig. 3, is rocked counterclockwise with its shaft 109, and a lever 114 fast on the shaft acts through an arm 436 and a shaft 437 to rock the offset end 442 of a locking lever 438 into engagement with one of the notches in a plate 439 carried by the total control lever. Similarly, depression of a key 30 rocks the foot 112 of a control sector 110 into engagement with a stud on the lever 114 to effect the same results. Depression of a key 31 is prevented when the total control lever is in its first position above or below the " Add position, by means of a slotted plate 446 that is set by the usual printing rack 457 to intercept the tail 445 of the lower supporting arm 105 of the detent bar 103. Depression of a key 30 is prevented when the total control lever is in its second position above or below " Add" position by a cam slot 189 in the total control lever, that through arm 187, shaft 178 and arm 177 holds a pin 176 in engagement with the cam shaped end of an arm 115 of the control sector 110 which is thereby locked. Depression of a key 30 or 31 is prevented when the total lever is moved to its third position above or below the "Add" position by blocks 462 on the total control lever, that intercept the offset end 442 of the arm 438 and thus serve to lock the keys 30, 31 in the manner already described.
