Abstract: 10,785. Haddan, R., [National Cash Register Co.]. May 1. Cash registers with operating-means; voucherissuing.-A cash register of the type described in Specifications 9400/97 and 1408/04 is provided with voucher perforating, printing, and delivering means and also with means, normally inoperative, for feeding-in to the printing-point and returning detached slips, the internalvoucher feed &c. apparatus with the constantmatter printing-mechanism thereof being rendered inoperative when the detached-slip feeding-means is put into operation. Consecutive numbers and dates are printed upon all the records. The voucher apparatus comprises perforating-rolls 79, 82, Fig. 6, constant-matter printing-rolls 88, 68 and 75, 76, a platen 108 for recording the transaction from item typewheels 39 positioned through the differential mechanism set from the keyboard, a knife 119 for detaching the voucher from the strip, and a feed-wheel 164 for ejecting the voucher from the machine. This feed-wheel 164 is also employed for feeding and ejecting the detached slips. Two records of each transaction are recorded on the voucher, one on each side of the perforation, the roller 75 having a raised portion 99 for giving an additional feed after the first operation of the platen 108. To render the voucher-issuing and constant-matter printing- means inoperative, the perforating and printing rolls are separated; one of each pair is mounted upon an eccentric 97, the lowest being mounted upon a shaft 53 and the others connected by linkage. To rock the shaft 53, one of three special keys 41, 42, 43, Fig. 2, is depressed and moves a plate 46 so that a roller 54 carried by it comes under the action of a cam 55 and causes a slot 50 to bear upon a pin 51 of a link 48 pivoted to a crank 52. The feed-wheel 162 is carried by an arm 166 operated by cams upon a shaft 173 connected by gearing to the operating-handle; the cams raise the wheel into contact with a knurled wheel, and the rotation for feed is obtained from a toothed sector 187. A bell-crank lever 188 is mounted upon a fixed pivot 189 and has an adjustable pin-and-slot connexion with the sector; its upper end 195 is spring-urged in a clockwise direction against a stop 194 carried by a lever 61 for operating the record-strip platen 60. On the operation of the lever 61, the stop is depressed, and the lever 88 moves the sector 187 up as the roller 164 swings upwards; on the return movement of the lever 61, the bell-crank lever 188 is pushed back, thus rotating the wheel 164 to eject the voucher. In the use of the wheel 164 for feeding-in slips, the oscillation of the shaft 53 is transmitted through levers 85, 208, Fig. 4, to a surface cam which causes axial movement of the cam-carrying sleeve on the shaft 173 and brings into operation other cams 180, 201, 203, which cause the roller 164 to feed the slip in farther after the first impression from the type-wheel 39, and to eject it after the second impression. The amount of feed given by the wheel 164 is varied by adjusting the bolt 191 in its slot. The lever 61 for operating the platen 60 for the recordstrip may be disabled during slip-printing operations. The voucher perforator is described in Specification 16,242/14. Zeroizing-mechanism.-The consecutive-number printing-apparatus comprises type-wheels 224, Fig. 11, mounted upon a sleeve 226 which is loose upon the shaft 37. At each operation of the machine, a cam-operated yoke actuates the numbering-device, which is of the ordinary deep-notch type. A cap 245 for resetting the consecutive number device to zero is fixed to a sleeve 244 and has two slots 246, one of which normally engages a pin 247. The sleeve 226 has a cut at its end to receive a tongue on the end of the sleeve 244, this tongue being longer than the pin 247, so that when the cap is pulled axially to free the pin 247 and is then turned, the number-wheels 224 will be zeroized.
