Abstract: 14,137. Haddan, R., [National Cash Register Co.]. June 11. Cash registers with operating-means. - Relates to key-set handleoperated multiple-bank machines. In addition to the grand totalizer, two groups of totalizers are provided, and an item may be registered simultaneously in two totalizers, one selected from each group. Each clerk has a separate cash drawer, and the clerks' totalizer - selecting mechanism is also employed to select the drawer. Operating-means; differential mechanism.- Two revolutions of the operating - handle are necessary in order to impart the necessary single turn to the main shafts 45, 23, 244 of the machine, Plunger keys 1, Fig. 3, rock a stepped differential segment 4, Fig. 4, in each bank, thereby rotating pinions 17, Fig. 8, having a pin drive for arms 20 according to which the pin recedes from the arm upon key depression, and upon operation the shaft 19 carrying the pinion is given a complete rotation in the opposite direction, restoring the pinions 17, now coupled by broad pinions 26, each with two similar pinions 29, 30, of which the pinions 29 mesh with large segmental gears 33 and have pins engaging the arms 20, so that when the pinion-shaft 19 is given its forward movement, the pins and segments follow the arms, while upon the return movement, the broad pinions 26 are out of engagement and merely the return of the segments is effected by their pinions 29. From the other pinion 30 the actuation of the receiving-pinions 78 of the totalizing-counter is derived, but in the case of transactions other than cash sales, a lever 90, rocked by a pin upon the differential segment assigned to the special keys, cams laterally the conical end of a shaft 91 carrying the broad pinions 26, which thereupon move out of engagement with the totalizer actuating-pinions 30, which become locked by detent members. The large segmental gears continue to communicate the differential setting to the shaft 95 and to sleeves and segments thereon whereby the differential racks 162, 100, Fig. 16, for the special totalizers and clerks' totalizers respectively are adjusted. The special indicator 101, Fig. 3, is rectangular, with duplicate lettering, and derives movement from the special-key segment 33 through the mechanism shown. Machines with several item-value totalizers; cash-drawer mechanism.-The special-indicator setting parts are arranged to position differentially two slides 144, 145, Fig. 19, thereby moving one of a series of pins 146 carried by the slide 145 between the shoulders 147 of a corresponding link 148 adapted to effect engagement of one of the special totalizers with the actuating rack-bars when the main operating- mechanism rocks the slide about its pivot on the special-indicator spindle 102, while the slide 144, with vertical movement only, brings a notch 170 opposite a locking-pin 173 upon the engaging- link to permit the movement. Fig. 16 shows the train of parts communicating differential motion from the concentric sleeves 96 to the actuating-racks 162, 100 of the special and clerks' totalizers, including segments 98, broad pinions 178, segments 97, and gears 179, which by pawl action carry their shaft 182 in the same direction to the extent of the maximum setting. The main operating - mechanism subsequently returns this shaft to the original position, with resetting of all the segments 97, with which, however, the broad pinions no longer engage. but before this takes place the desired special and clerks' totalizers have been engaged, so that upon the upward stroke of the racks thus effected actuation takes place. Fig. 19 shows the mechanism for selectively engaging one of the clerks' totalizers and for opening the corresponding cash drawer, a differential setting of a slide 223 by the clerks' key bringing the turned end 230 of one of a number of lever-arms 225 opposite a shoulder 228 upon a spring-rocked lever 229 released by the main operating-mechanism, causing the end of the lever-arm to project through the corresponding opening 227 in an upright 226 and rocking an engaging-spindle 233 for the corresponding clerks' counter. These parts are subsequently positively reset. The selected drawer is opened upon the raising, by the operating-mechanism, of an upright bar 238, Fig. 26, to which levers 236 are pivoted, one for each drawer, so that the lever which finds its right extremity obstructed by the projection through the corresponding aperture 227 rocks clockwise and lifts its drawer-latch link 239. A ' throw-out ' mechanism for the clerk's totalizer is operative upon depression of the ' Paid Out ' and ' Charge ' special keys, but does not affect the opening of the clerk's drawer. For this purpose, a lever 399, Fig. 19, is depressed to bring the upper part of a slot 402 therein over a pin 400<a> of the spring-rocked lever 229. the movement of which is sufficiently limited thereby to prevent engagement of the selected totalizer while projecting the lever arm to co-operate with the drawer latch. Transfer mechanism.-The transfer cams upon the totalizers 175, 235 displace a several-toothed transfer-trip slide 188, whereby either a pin 189 forces a spring stop-lever 190 upon the higher rack-bar out of alinement with a fixed stop 192, or else comes into such a position that this happens upon the return of the rack to normal. The stop-levers also become engaged with two-armed levers 193 rocked by the main operating-mechanism to impart positively an additional one-step movement to the selected levers in succession, the connexion with the actuating - segments having previously been broken by the lifting of a series of broad pinions 184, coupling gears 179 to companion gears engaging with the racks. The trip-slides are held in displaced position by pawls 209, 210 until released and positively restored by the operating-mechanism.
