Patent GB-166007-A (GB)
Abstract: 166,007. Julius, G. A. May 15, 1919. Cash registers; transfer mechanism.-Relates to the total indicators at a central station in a totalizator or ticket-issuing system, operated from a distance electrically by circuits as described in Specification 166,221, and comprises means for increasing the speed of registration on the counter to correspond with increase of operation at the distant stations, and means for locking the distant stations against use if a predetermined high rate of operation is exceeded. The indicating drums show the money value of the tickets issued. The units and ten indicating drums 102, 103, Fig. 2, respectively are fast with pinions 111, 110 respectively driven by gear wheels 130, 249, Figs. 2 and 5, ten turns of each of the latter giving one turn of the numeral drum and half a turn of wheels 133, 136. The axles 129, 248 of the wheels 130, 249 are under constant torsion from pulleys 128, 127 on them which gear by slipping belts with pulleys 114, 123. The pulley 114 is integral with a power-driven pulley 116 both being mounted on a shaft axially controlled by a spring 112 and carrying a friction disc 119 between which and a parallel friction disc 122 integral with the pulley 123 is fitted a friction pinion 120 vertically guided by a shaft 121, Fig. 3, which carries it, and balanced by a spring 201. By this means the rate of drive of the unit drum can be considerably increased, the position of the friction pinion 120 being controlled by a link 193 and bell-crank lever 195, 196 having a pin 197. Fig. 2, bearing against a lever 198. This is pivoted to the end of a rod 200, Fig. 7, under control of the units mechanism operated from the distant stations. Values transmitted from the distant stations are added on both units and tens denominations by electromagnetic escapements 92, 96, Fig. 9, applied to differential gears shown in Fig. 7, the spiders of which are pinned to spindles 151 and attached to one end of springs 158 the other end of which are attached to gearwheels 133, 136 which have sleeves 175, 157 covering the springs and running on ball-bearings fitted to the spindles 151. The wheels 133, 136 have hubs internally threaded to engage screws 161 grooved to slide in and engage feathers on the spindles 151. Thus the drive through shafts 129, 248 winds up the springs 158 and normally maintains the " lead " screws 161 in outward position, as shown in Fig. 7, keeping the rod 200 controlling the friction pinion 120, and a similar rod 163 for the tens, outward for low speed drive. Also in this position stop arms 188, 166, the latter with a spring buffer head, are opposite holding arms which engage stop pins 187, 250 on the driving wheels 128, 127. On receiving an impulse from a distant station the tensioned spring drives the released escapement, moves the lead screw 161, releases driving wheels 127 or 128 to restore it and so actuates the indicator. A heavy call on the indicator actuation moves the friction pulley 120 increasing the speed, and if the call is too great by means of either units or tens lever 198, 219, Figs. 2 and 7, a spindle 209 is rocked to depress one or other of a pair of links 212 to release a spring-controlled lever 218 to pull out a knife switch 203 and disable the distant stations. Transfer from units to tens drum is effected by pins 134, 135 on the pinion 133 engaging an arm 139 on a shaft 141 to operate an electromagnet escapement 174. Transfer from tens upwards is by pawls 225, Fig. 3, on a frame 221, 224 rocked by a cam 229, the pawls having rolls 235, Fig. 2, to run in gapped flanges on the lower wheels. Detent pawls 236 are fitted, and the movement of the frame 221 is controlled by a dashpot 240 and spring 241.
