Abstract: 2184. National Cash Register Co., [National Cash Register Co.]. Jan. 28. Receipts, checking and recording.- Cash registers of the type which are set by positioning levers on graduated arcs, and are subsequently operated, have attachments for printing, on the check and on the detail strip if desired, an unabbreviated word to denote the transaction. The levers 22, Fig. 2, operate indicator - wheels 40<a> by means of rack-bars 30 and segmental racks, and have also toothed aligning- plates 29, which co - operate with spring-pressed bolts 75, 74 and the yoke frame 72 to throw a pin 172 into a recess in a disc 133 on the driving - shaft 61 when a lever is operated. The lever and driving- handle are thus reciprocally locked. Four amount printing-wheels, a clerk's initial wheel, and the special transaction wheel are mounted on nested sleeves on the shaft 180<a>, Fig. 1, the first four wheels having types diametrically in duplicate, whereby from one setting impressions may be simultaneously obtained on the check and the detail strip. The toothed segments 28<a> and pinions 181 set these wheels. The specialtransaction word is preferably printed on the check by a printing-wheel 310, driven from the corresponding wheel on the shaft 180<a>. The platen for the detail strip is a roller 185 on the lever 188, deriving motion from a pin 192, engaging in a cam groove of the disc 190 on the driving-shaft, and carried by a lever 290, also pivoted at 189, and adjustable, by means of set-screws 292, 294, with respect to the lever 188, with which it moves as one piece. The groove is such that the lever is rocked twice for one revolution of the driving- shaft, the first time to bring inking-pads against the type, and as it moves, the arms 197, 198 and pawl 196 rotate the feeding-roller 193. There are two platens 186, 315 for the check, the first for the main impression and the second for the auxiliary printing-wheel, and both are carried by the lever 199 oscillated by means of a pin 200 and cam groove 201, the check strip 183 passing down through a shoot and between a printing-roller 206, provided with dating and numbering types, and a feed roller 205 carried by an eccentric part 207<a>, Fig. 5, of the shaft 207. A sleeve 211<b> is provided, which is locked to the shaft by a pin 212<a>, but can be drawn out by hand against the spring 215 and placed in one of two positions in which a pin 219 on the frame enters a slot on the sleeve, the motion thus produced withdrawing the feed roller and diminishing the throw of the check platens, although the wheels 209, 210, through which motion is transmitted from the driving-shaft 61, remain in gear. The printing-wheels are inked by the pads 252, 253, 323 shown in Fig. 4, of which the first two are spring-pivoted to levers 256, one at each end of the wheels, and the third is for the auxiliary wheel 310 and is carried by the piece 322, and they are so moved by the cam groove 264, pin 263, rack 262, gear wheel 263<a>, and the levers 316, 322, suitably constrained, that on the short stroke of the platens the pads are forced against the types, but are displaced before the long or printing stroke. On the latter stroke the rim of the cylindrical platen 185 strikes the outermost of a number of aligning pawls 350, all on a common sleeve on the shaft 317, and forces them down against their springs into gear with toothed plates 351 below type level. The check shoot carries the ink roller 410 on arms 411, provided with a downward extension 412, pivoted at 413, and bearing a pin 415 which is forced backwards, when the checkfeed is thrown out of action, by means of the cam disc 416 and tappet 414<a>. A stationary knife 187<a> and a movable one 187<b> co-operate to cut off the check. In the modification shown in Fig. 7, the setting-levers 500 are loosely pivoted on a shaft 501 and operate the indicating-wheels 507, the registering driving segments 510 being under the tension of a spring 512 which keeps the lug 511 against the lever. A segment 541 on the lever sets the printing-wheels, and when the driving- shaft 561 is in its inoperative position, motion of the lever and its aligning-plate 531 simply forces back the pawl 532 into recesses in the bar 534, but on operating the shaft 561, this bar is moved longitudinally and the levers locked. Rotation of the driving-shaft causes the shaft 501 to move anti-clockwise, whereby the lug 514 engages with the pin 515 on the segment 510 and restores it to zero position, and simultaneously the cam surface 524 rocks the lever 521 and brings the registering- wheels into gear. The detail strip special transaction wheel may have duplicate characters and print on the check as well, and in the case of stub checks repeat printing mechanism may be employed.
