Title: Improvements in or relating to key-controlled transaction-recording machines
Filed: 1925-07-08
Abstract: 236,942. British Tabulating Machine Co., Ltd., (Assignees of Peirce, J. R.). July 9, 1924, [Convention date]. Type-wheel actions. - A key-set, motor-operated cash register adapted to print and perforate a record of the transaction on two portions respectively of a paper blank which is simultaneously severed, one portion being fed into a magazine for retention in the machine while the other part is ejected to serve as a voucher, comprises the type-wheel action and hammer-impression and sheetfeeding arrangements described below. The differential movements of the bars 114. Fig. 5, derived from the keyboard, are conveyed to the amount type-wheels 122 by means of toothed sectors 121 and to the amount punch-selecting arms 128, Fig. 20, by cross-over connections 124 and slide-bars having slotted uprights 127 to embrace pins on the arms 128 pivoted on a rod 130 supported by arms 169 from a shaft 168. In addition to the amount, the machine number and the date are recorded upon the blank as shown by Fig. 3. The machine number is recorded by punches selected by arms 144, Fig. 16, slotted to receive radial pins of a shaft 147. To set the arms, the shaft is turned through ninety degrees to disengage the pins from the slots and after the arms have been set the shaft is turned back to secure the arms again and is locked by a pin and slotted sector 149 mounted on the end of the shaft. The machine number type-wheels 142, Fig. 5, are set directly by hand and are held by pins. The date punches are selected by pivoted arms similar to those already referred to and positioned by means of finger levers 135, Fig. 1, co-operating with an index plate 133. The date-printing wheels 138 are set by the operator by means of wheels 140. The word " taken " is normally printed on the voucher by a pivoted plate 151, but when the goods purchased are to be sent the operator depresses key 85 to release a catch from a bar, the result being that under spring action this bar can slide and through a lever disable a togglelever support for the type plate so that this is lowered to ineffective position. Hammer - impression arrangements. - The pivoted platen 197, Figs. 4 and 5, is urged by a coiled spring 199 but is normally restrained by a latch 202 engaging an arm of the platen shaft. In the course of the operation of the machine a shaft 168 is rocked and this through a link rocks the catch clockwise to release the platen. Subsequently the platen is restored to cocked position by a link 204 connected with a shaft 207 rocked by cam mechanism 209 from the main shaft 40. Sheet-feeding arrangements.-The blank stored in a hopper 210 are fed singly, by a reciprocating picker 214, Fig. 5, connected by link 217 with the rock shaft 109, to a carriage 220, Fig. 21, slidable upon guide rods 219 and provided with a pair of clips at each side. Each pair of clips comprises an upper jaw mounted on a shaft 226 carried by pivotal arms 224 supporting lower jaws. The upper and lower jaws are normally urged together by a spring and are opened, when the carriage is moved to the left to receive a blank from the picker, Fig. 23, by means of an arm 229 secured to the shaft 226 and terminating in a roller 230 adapted to run up a cam plate 231. To allow the clips to close to grip the blank a lever 235 normally supporting the cam plate is released by the rocking of shaft 207 so that the clip spring can operate, to close the clips. When the carriage arrives at the printing and perforating position, abutments 237 mounted upon a shaft 239 are in the path of the blank to strip it from the clips, the shaft 239 being then rocked by cam mechanism to raise the. abutments so as not to obstruct the further movement of the card after printing &c. It is necessary that the clips should be lowered for the return journey of the carriage in order that they shall not move the blank back again and this is effected by a slidable plate 255, Fig. 21, which normally supports the arm 224 by means of a lug 256 and pin 257. As the carriage completes its travel to the right a stop 258 restrains the plate 255 so that the arm 224 falls and carries the clips down out of the way of the blank. Thesevered portions of the card are ejected from printing &c. position bv pushers 244, Fig. 5, supported from the rock shaft 207. The checks are thus thrust between pairs of feed rolls 246, 247 one pair of which, rotating faster than the other, feeds the perforated stub into the magazine 212, Fig. 1, while the other pair ejects the printed voucher from the machine.
