Abstract: 923,383. Cash registers combined with coin-dispensers. NATIONAL CASH REGISTER CO. Jan. 17, 1962 [March 17, 1961], No. 1692/62. Class 106 (1). In a registering machine combined with a coin dispenser, there is provided a normally blocked switch for actuating the coin dispenser which is unblocked by the setting of differentially moved members during one machine operation so that the actuating switch is operable during a subsequent machine operation. With each bank of operation switches is associated a differential rack 147 which sets notched wheels 198 to 203 and 209 (Fig. 5). During a machine cycle the position of the wheels is sensed by feelers 204 (for wheels 198, 199, 201, 202), 205 (for wheel 200), and 206 (for wheels 203, 209). Fig. 3 shows the typical feeler 204 which is urged into engagement with the notched wheels by a spring 213 attached to shaft 208 on which the feeler slides, but is restrained by arm 211 on shaft 210 acting on stud 212 of bell-crank 240. Feeler 204 ends in a finger 218 and has pivotally-attached fingers 214 and 215 and 216 (level with, but behind finger 215). After release of the feeler by rotation of shaft 208, if notches register with finger 218 and either finger 214 or fingers 215 and 216 the feeler is able to move to the left, rotating bell-crank 240 clockwise and depressing rod 233. In the circuit of the coin dispenser (Fig. 13, not shown), are switches 269, 270 in series. Switch 269 is closed by camfollower 225 during every machine operation. Switch 270 can be closed either by switch arm 230 (Fig. 3), or switch arm 231 (Fig. 4). Switch arm 230 is connected to rod 233 and is thus controlled by feeler 204. Switch arm 231 is linked in similar fashion by rod 234 to feeler 205. Arm 231 is spring connected (Fig. 4), with a stop arm 235 and in a normal position lips on arms 231 and 235 are engaged by a flange 249 on disabling arm 243, movement of which is controlled by rod 246 connected to feeler 206, so that clockwise movement of arms 231, 235 is prevented. In a first machine operation notched wheel 209 is so positioned that feeler 206 moves to lower rod 246 and rotate arm 243 anticlockwise. This releases stop arm 235 to its spring until the arm engages pin 238 on arm 231. Movement of rod 234 and this feeler 205 is now possible and in a later machine operation the coin dispenser is operated. At the end of this operation the arms 231, 235 are re-engaged by disabling arm 243. The process above described occurs when a set of cheques are to be cashed. A List key is depressed, the amount of the first cheque is set on the keyboard and the Cashed Cheques key depressed. This enters the amount on the keyboard into an add-subtract totalizer the setting of which completes circuits to the coin-dispenser solenoids, and also releases switch arm 231 for future operation. After all the cheques have been entered, depression of the Total key clears the totalizer and causes switch arm 231 to operate. Switch arm 230 is directly controlled by feeler 205 and is operated when the Cashed Cheques key is operated alone, or the Cash-Out key, or the combination of the List with the Cash-Out key. The use of these keys in conjunction with three sets of totalizers in the machine and tape and step-marking mechanism (not described in detail) is explained in the Specification. Operation control differential.-A row of control keys 121 to 129 controls the positioning of slides 147, 169 (Fig. 2). A cam 179 on a motor shaft rocks lever 175 clockwise which rotates driver arm 172 clockwise (Fig. 2A). A latch 158 (Fig. 2B), engages a recess 171 in arm 172 and rotates both an arm 161 to which it is attached and a toothed segment 153, meshing with slide 147, to which it is connected through a pin 157 engaging a cam slot in the segment. When slide 147 is arrested by a depressed key the slot cams latch 158 free of recess 171 and the surface of arm 172 holds the latch in engagement with a locking member 185. When arm 161 is thus stopped a lever 162 is fixed at end 163 and pin 164 at the other end rotates a toothed segment 167 engaging slide 169, as the lever is acted on by roller 180 on lever 175.
