Abstract: 572,103. Totalisators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. Dec. 10, 1943, No. 9333. [Class 40 (i)] [Also in Group XXXVII] In an electric totalisator system, the same ticket-issuing machines have provision for ordinary win, place and forecast betting and also for reverse forecast betting, i.e. the selection of two competitors for first and second place in both orders, and field forecast betting, that is the selection of one competitor for first place and the field for second place or vice versa. Means are provided for varying the operation in accordance with the number of runners and for preventing the issue of a ticket in the case of faulty operation. Specification 468,381 is referred to. Win and place bets. A stake is selected by one of the first five keys in the upper strip and a competitor by one of the first six keys in the lower strip and the win or place key W or P is operated in the middle strip. Relays WS, WR, WC are operated to associate the keys with a group of win and place competitor and total aggregators (not shown). Simple forecast bets. A stake is selected as before, the competitor for first place is selected by one of the keys 1& to 6& in the middle strip and the competitor for second place by one of the keys 1 to 6 in the lower strip. When a complete set of keys has been operated, mechanical means (not shown) allow a spring- driven cam assembly to move into a " ready " position in which as shown, ground is connected over a contact CM3 to one of the terminals in the outer ring of a distributer D which is normally running at a high speed. Two wipers, one ahead of the other, engage this ring and when the leading wiper encounters a grounded contact (CS being normally energized) a circuit is made for a latch magnet LM which, by means not shown, slows down the commutator and at LM1 connects up the trailing wiper. At the same time, a circuit is made from ground over the corresponding terminal in an inner ring for a relay OP (RN being already energized as described in the paragraph below on faulty operation). OP connects ground to the key strips to cause the operation of the stake relay 2S ... 10S selected by the operated key in the upper strip and the combination relay such as 1 and 2 selected jointly by the keys in the other two strips. These relays select the appropriate combination aggregator such as 39 and the appropriate stepping magnets in this and in the total aggregator 40. The magnets in the combination aggregator complete a circuit via contacts of the combination relay for a relay RC and those of the total aggregator, via contacts of the stake relay, for a relay AC. A circuit is also made in parallel with one of these according to the position of a key CCK for a relay TC in the issuing machine. Operation of the relays OP, TC acts mechanically on the mechanism to cause the ticket to be printed and issued and the mechanism is finally stopped in a position of the cam CM such that CM3 is open and the relays are released. Reversed forecast betting. The competitors are selected as before but, instead of a stake key, the key REV in the upper row is operated. This causes the operation of a relay RS which arranges for the operation of the 2 /- magnet in the combination aggregator selected by the operated combination relay and also that in the aggregator of the reverse combination, and for the operation of the 4/- magnet in the total aggregator. Field forecast betting. The competitor or the field is selected for first place in the middle key strip and the field or competitor for second place in the lowest strip, the key FD being operated in the upper strip. This results in the operation of a relay FS and of one of six pairs of relays such as 1&F, F&1 in accordance with the competitor selected. These cause the operation of the 2/- magnet in all the combination aggregators concerned and of the appropriate magnet in the total aggregator. Their action is modified by a number of non- runner relays 1NR ... 6NR which are operated when the corresponding competitor is not running. The amount to be registered on the total aggregator is looked after by a switch MNCS, the position of which depends on the number of non-runner keys NK1 ... NK6 actuated and causes the operation of one of a group of relays 3R ... 6R accordingly. The circuit for relay ‹ RC involves contacts on all the combination aggregators involved and that of AC involves contacts of the relays 3R ... 6R. Faulty operation. The operator at an issuing machine sets a switch RNS to a position corresponding to the race concerned and the switch NCS to a position depending on the number of runners. Unless these positions agree with the operation of a race-selecting key strip (RNK of which is shown) and of the switch MNCS at the aggregator position, the relay RN cannot operate and no tickets can be issued. If either of the relays AC, RC fails to operate in response to the signal from the aggregator magnets, a circuit is made for HU which locks the operated relay and prevents the sending of further actuating signals from the inner contact ring of the distributer until the fault has been cleared and key HORK has been actuated. Mechanical arrangements are made to prevent incorrect .operation of the keys, but if two or more stake relays or two or more competitor relays are operated at once, marginal relays SG, RG are operated and operate corresponding relays SL, RL which lock under key control and energize the hold-up relay HU. Lamp signals indicate the nature of the fault. If a non-running competitor is selected, a circuit is made for a relay such as A, B which energizes the " cancel " solenoid in the issuing machine.
