Patent GB-343605-A (GB)
Abstract: 343,605. Totalizators. CLAYTON TOOL CO., Ltd., India Pavilion, Wembley, Middlesex, and CAMP, E. G., 17, Tudor Close, Kingsbury Hill, London. Nov. 26, 1929, No. 36233. [Class 106 (i).] In an electric totalizator the value of the stake is transmitted to the counters by one or more of a number of unit impulses during one cycle of operation of the ticket issuing apparatus. The operator adjusts a switch to the stake value, sets another switch for win or place, rotates a setting- arm to the number of the horse and then depresses a button to set a motor in operation. By the setting of the arm a circuit to a horse-selector switch is made and broken the necessary number of times to position this switch in correspondence with the arm, whereby the value-impulse circuits are extended to the desired denominational units of the selected horse counter and of the pool counter. General arrangement. Two horse counters 241, 242 and a pool counter 300, duplicated for win and place betting, are shown in the diagram, the horse counter being wired to corresponding contact on three banks 47, 48, 49 of a selector switch 46. The banks are connected respectively with the actuating magnets 120, 121, 122 of the shillings, units of pounds and tens of pounds wheels of the counter and the brushes are wired to the win and place switch 60 and thence to the transmitting-station. The pool counter actuating-magnets are connected directly with the switch 60 and are operated by impulses in the same way as the horse counter magnets. Transmitter; horse selector. The horse-selecting arm 42 is rigid with a contact arm 44 traversing a ring of contacts 101 multipled to a lead 144 wired to a magnet 143 for stepping the horse selector switch 46. As the arm 42 is moved to the desired horse number therefore, the circuit to the magnet 143 is made and broken successively so as to cause the switch to advance to the same extent. According to the Provisional Specification means are provided for reversing the magnet drive to enable the switch to be moved backwardly by similar motion of the arm 42. Win and place setting. By means of a fingerlever 100 a contact arm 55 may be set to put either of two magnets 58, 59 in circuit so as to throw over a number of arms 63 .. 68 to connect up either the win or the place totalizing-apparatus with the transmitter. Stake value selector. An arm 52 may be placed in any of six different positions according as the stake is 2/6, 5/-, 10/- ú1, ú5, or ú10. Movable with the arm is a wheel 95 carrying a contact arm 54 adapted to engage selectively three pairs of contacts 83, 183; 84, 184 and 85, 185, the pairs corresponding with the three denominations of shillings, pounds and tens of pounds, and the two contacts of each pair being connected through switch 60 with the horse and pool counters respectively. Stake value impulse switch. The setting for value effects through wheel 95, the rotation of a wheel 94 provided with variously spaced and dimensioned contacts 93 adapted to be engaged by brushes 92 depending from other contacts 90. Arranged to wipe over the latter is a contact arm 89 rotatable by a motor having brake and clutch coils 106, 108 respectively. When the arm 52 has been set to a particular value, say 10/-, the contacts 93 are so disposed that one rotation of the arm 89 will cause four impulses to pass to the arm 54 and thence to the counters. Action. The characteristics of the bet having been set up, the operator depresses a button 102 on the horse-selecting arm 42 to open the circuit to the motor brake coil 106 and close that of the clutch coil 108. The motor then drives the arm 89 for one rotation to send the necessary number of impulses to the required denomination of the counters. To prevent more than one rotation of the motor, its controlling circuits include a switch comprising two insulated drums 110, 111 and three fixed brushes 113, 114, 115. Normally a projection from drum 111 lies under brush 114 and the brake coil is in circuit. When the button is depressed this circuit is broken at 103, 104 and as soon as the motor starts it is broken also at 114, 115. If the button is now released the clutch circuit is maintained by the brushes 113, 114 until the rotation is complete, when the projection breaks this circuit and re-establishes the brake circuit. Transfer. Each denominational wheel of the counters makes a contact at 127, 128 when passing to 0 and thus closes a circuit from a line 130 to the actuating-coil of the next higher wheel. Zeroizing-arrangements. To zeroize all counters a key 133 is operated to energize a magnet 132 and so throw over a switch-arm 131 to break the transfer line 130 and connect up lines 129 leading to the actuating-magnets of all denominational wheels. When any one wheel reaches 0 the circuit of its magnet is broken by a commutator which rotates with the wheel and has no contact at the 0 position (126). The Provisional Specification describes somewhat different constructions of the stake value selector and impulse switches.
