Abstract: 549,667. Cash registers. "NATIONAL" REGISTRIERKASSEN AKT.-GES. and DEUTSCH, J. March 7, 1941, No. 11518/42. Addition to 547,565. [Class 106 (i)] The issue of the variable number of bonus tickets or stamps instead of being controlled by the differential mechanism as in the parent Specification is controlled by mechanism differentially set from the indicator mechanism. Front and rear indicator plates 105, 106 are set from the key-board by the well-known differential mechanism of Specification 8119/15, [Class 106 (i)]. The segment 208 has teeth engaging a rack 210 fast with the indicator frame 104 which moves rearwardly on operation of the machine to an extent corresponding to the key depressed, and a member 212 raises the corresponding plate in each set 105, 106 to viewing position. Resting against the frame 104 is a spring-pressed feeler lever 110 which is thus positioned according to the key depressed. The lever 110 for each of the four key banks is fast on one of a set of telescoped shafts 157, 163, 165, or 167. Fastened to the other ends of the shafts are stop levers 158, 164, 166, 168 adjacent the bonus ticket issuing means. These levers co-operate with a disc 116 having portions of varying height so that the discs are arrested differentially according to the angle through which its associated lever has been rocked. Control of issue of bonus tickets.-As these are similar, only that for the units of cents is described. The disc 116 carries a stud 117 on which is a back check part 119 and a stud 118 on which is a feed pawl 120. Loosely mounted on the hub of a ratchet wheel 156 fast on drive shaft 122 for bonus ticket issuing mechanism are a ratchet wheel 123 and driving gear 124. Loose on the shaft 122 is a ring 126 to which is attached one end of a spring 127 anchored to the frame at the other end. The disc 116 is rigidly connected to the ring 126. Gears 131, 132 transmit the drive of gear 124 to roller 133 feeding strip from a roll 159. Two feed rollers 130 are located above and two below the shaft 122 for compactness. Each roll 130, 133 is adapted to add one unit to a related counter 134 or 135 each time a bonus ticket is issued. The driving shaft 137 drives through gear 138 a wheel 139 fast on shaft 122 or the wheel 139 is driven by motor. On the shaft 122 is a long arm 142 adapted to co-operate with pawl 119. A spring 143 couples pawls 119, 120 and presses pawl 119 towards the shaft 122 and pawl 120 into engagement with the teeth of ratchet 123. The pawl 119 in Fig. 1 position engages a stop pin 144. A cam disc 145 fast on the shaft 122 is adapted to co-operate with a pawl 147 pivoted at 153 on a lever 146 mounted on a shaft 172 on which is also a control lever 148 with unequal extensions one of which co-operates with disc 116, Fig. 1, and the shorter with the gear 124, Fig. 4. A spring 149, Fig. 2, tends to maintain the lever 148 operative and a spring 150 to maintain pawl 147 against the cam 145. Loosely mounted on the shaft 172 is a lever 151 connected by link 152 to a bell-crank pivoted at 231. The lever 151 acts as a stop for pawl 147. When "Net Sales" or other transactions not subject to a bonus are recorded on the machine, the lever 151 is moved into the position shown by dot- and-dash lines; Fig. 2, and does not obstruct the pawl 147. Thus when cam 145 is rotated clockwise, the pawl 147 rocks idly on pivot 153 and the stop disc 116 and gear 124 remain locked, pawl 119 remaining against stud 144. Disabling of bonus issue by transaction keys.-When a " Gross Sale" key 261 is depressed, the link 207 rocks the segment 208 so that a nose 23& is rocked clockwise. The spring 237 acting through levers 152, 232 moves the arm 234 clockwise and lever 151 moves into " full line" position, Fig. 7, permitting operation of stamp issue. When " Net Sale" key 266 is depressed, the nose 238 is rocked counterclockwise, and lever 234 moved in the same direction by stud 236. This causes lever 151 to. move to dot-and-dash position where stamp issue is disabled. When a key is operated in the " Add" or " Slit bank no issue takes place as long as "total lever" 256 is in normal position. When such key is depressed, the lever 239 is rocked and the rod 240 rotates cam disc 221 and pitman 223 to dot- and-dash position which through rod 233 and bell-crank 230 moves lever 151 to the disable position.
