Patent GB-233702-A (GB)
Abstract: 233,702. Setright, H. R. May 8, 1924, [Convention date]. Checking and registering receipts.-In an electrically operated totalizator improved means are provided (1) for receiving the electrical impulses and for storing them when they are being received faster than they can be transmitted to the counting drums, and (2) for actuating the counting drums from the receiving mechanism. When a ticket is to be issued from one of a number of associated ticketissuing machines (not shown), an electrical circuit is completed through a selected pair of contacts on that machine, thus causing an electromagnet 154, Figs. 3 and 9, corresponding with the machine, to be energized. The circuits of the different machines are controlled by a rotary relay switch, Figs. 11 and 12, which acts to maintain the circuits closed, if energized, until the totalling mechanism has had time to function. The switch comprises a continuously rotating shaft 114 carrying an arm 119 having contacts 124, 125, 128 adapted to wipe segments 143, studs 142, and a ring 141 respectively. The latter parts are carried by a fixed plate 116 and the segments and studs are connected in pairs by strips 146. When the wiper 125 contacts with a stud 142 in the circuit of a ticket-issuing machine which has been actuated, the circuit 150 of the electromagnet is energized and its arm is drawn down to complete at 140 a shunt circuit through the corresponding segment 143. The electromagnets 154 rock escapements 110 which control escapement wheels 109 mounted on a series of epicyclic gears connected with a shaft 77. This shaft rotates under the action of a coiled spring 76 when an escapement is released. It is coupled at 79 to a shaft 102 carrying a worm 103 which gears with a wormwheel 98 mounted on a stud 96, Figs. 3 and 6. The worm-wheel also gears with a worm 69 on a shaft 68, and its stud is mounted on a slidable. sleeve 95 between which and a coiled spring 107 are arranged a pair of collars 105, 106. A crossshaft 87 carries at one end an arm 88 which is engaged by the collars, and at the other end an arm 89 adapted to engage a tooth 44<a> on a stop disc 44 carried by the end of the actuating shaft 28 of the counting mechanism. The sliding movement of the sleeve 95, which occurs when an electromagnet 154 is energized, thus releases the power-driven shaft 28 to actuate the counter and also rotate the shaft 68 in order to return the sleeve to locking position by the action of the worm 69. The shaft 68 keeps the spring 76 wound up through gearing 70, 71. Counters actuated by independent agency.- The shaft 28 when released is driven by friction from a continuously rotating member 43 which is driven by gearing 38, 39, 40. A worm 27 on the shaft engages a worm-wheel 26 on a sleeve 29 which has an arm 30 having a resilient connection with the units drum 22. A resilient connection is also arranged between the shaft 28 and the stop-disc 44. Transfer mechanism.-A continuously rotating shaft 47 geared to the rotary member 43 is adapted to drive sprocket wheels 54 by friction when escapement wheels 55, Fig. 8, attached to them, are released by the rocking of spring-controlled escapement levers 60. Pins 57 on the counter drums are arranged to engage the levers 60, and the sprockets 54 are connected by chains 53 to corresponding sprockets on the drum sleeves.
