Patent GB-341991-A (GB)
Abstract: 341,991. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, SMITH, L. W., 9, Meadow Road, and LYDEN, T., 4, Melrose Avenue, both in Beeston, Nottinghamshire. Oct. 30, 1929, Nos. 32952/29 and 25732/30. [Class 106 (i).] In an electric totalizator, means are provided whereby an entry in the totalizing equipment may be cancelled and the corresponding ticket endorsed. The cancellation is initiated by setting a cancel key and then the competitor key concerned, whereupon the competitor and pool totalizers are operated to remove the wrong entry, the original ticket is endorsed and a ticket is passed to a locked compartment in the ticket-issuing machine. The totalizers are rectified, in the present embodiment, by forward movement of the denominational element concerned, to the extent of nine steps. The number of cancellations initiated at any one machine is registered on a counter. Registering a bet, (normal operation). Fig. 1, shows some of the arrangements at a transmitting station for entering bets of ú10 and Fig. 2 illustrates the central collecting and counting equipment for ú10 bets in respect of one horse. A line 32 is shown as directly connecting up the particular machine but arrangements such as those described in Specification 338,273, [Class 106 (i), Calculating &c.], may be adopted for reducing the number of lines. The line 32, and similar lines 25, 26, &c. from the same competitor key at other transmitting stations, lead to contacts of a collecting-switch G. When the competitor key K2 is depressed a relay KL is energized to lock the cancel key K1, and a contact 31 completes circuit through a resistance Rl and relays P, F. Relay P is not sufficiently energized to operate but relay F operates and at #1 closes a circuit for the magnet of switch G which then hunts to find the marked contact. When this has been done the earth potential on line 32 is extended by wiper g2 to relays H, I. Relay H breaks the operating circuit of switch G at h1 but relay I does not yet operate owing to the resistance R1 in the circuit. The contact h2 completes circuit for a slow relay W, and contact w1 then causes energization of the magnet of counting switch N and a relay X. If switch N is at zero, wiper n2 allows a relay Y controlling the indicators to operate and this relay is then held by a circuit through the control key K3. Relay X at x2 by shunting a low resistance R4 across relays H, I increases the current in line 32 sufficiently to operate relay P whereupon p1 closes line 28 leading to the pool totalizer and contact p2 closes circuit for a relay Q and the ticket-machine motor CW. Relay Q holds itself through contact q2 and contact q1 opens the circuit of relays P, F, H. When the ticket has been printed and issued the motor releases the depressed key K2 and contacts q1, q2 are mechanically restored to normal. Release of relay H releases relay W and this in turn releases relay X and the magnet of switch N which then advances one step. Indicating by monogrammic signs. Operation of relay Y referred to above connects earth at y1, Fig. 2, to line 38 leading to the lamp circuits, and at y4 earths the wipers n4, n5 of the counting switch, the bank contacts of which lead to relays controlling the combinations of twenty-two lamps necessary to produce the required digits as described in Specifications 340,280, 340,288 and 340,289. If desired more than one indicator may be provided for each competitor and Fig. 3 shows a duplicate arrangement for this purpose, a switch ND stepping synchronously with the counting-switch N owing to the operation of a contact z1 by a relay Z energized by a line 39 under the control of contact w3 of relay W. The circuits of this second indicator are controlled by contacts of a relay YD as in the first arrangement, this relay being energized by contact y3 of relay Y. To ensure the display of noughts to the right of a higher significant figure, each relay such as Y is under the control of a line 42 leading from a contact (such as y5) pertaining to the counting-arrangements of the next higher denomination. Normal transfer. If a bet is received with counting-switch N, Fig. 2 on its ninth off-normal contact, wiper n3 in conjunction with contact w2 of relay W closes circuit for a relay T, which then operates and locks up at t1. Contact t2 now completes a circuit including resistance R5 and relay U leading through line 43 to a relay FA, Fig. 5, belonging to the next higher denomination. Relay U is not sufficiently energized but relay FA operates and causes collecting-switch GA to hunt and find the marked contact whereupon the operations described in the case of Fig. 2 take place in the ú100 assembly, Fig. 5, and the counting-switch NA advances one step. Normal operation of pool totalizer. As described above, relay P, Fig. 1, in operating closes circuit through line 28 leading to a relay AP in the corresponding denominational assembly of the pool totalizer (Fig. 9). Lines from other ú10 transmitting stations similarly lead to other relays AP with their co-operating relays EP, CP. Moreover a transfer line 45 leads from the ú1 assembly and controls further relays APA, EPA. Relay AP when operated is held through its left-hand winding and contacts ep1, ap3 and by means of contact ap1, collecting-switch GP is caused to hunt to find the contact of wiper gp3 marked by contact ap2 whereupon relay BP is put in circuit to break the switch drive at bp1. Circuit through relay CP is closed by contact ap4 but owing to resistance R2 at the transmitting-station the relay is insufficiently energized to operate. Contact bp2 causes slow relay WP to operate and through its contact wp1 energize the magnet of the counting-switch NP. If this is the first bet signal received relay YP also operates and is held. By reason of a contact wp2 relay EP is operated and its contacts ep1, ep2 break the circuits to relay AP thus causing release of relay BP and in turn of relay WP whereupon the counting switch advances one step. The indicating and duplicate indicating arrangements of the pool totalizer are similar to those already referred to in connection with the competitor totalizers, as also are the transfer devices. Cancellation on competitor totalizer. Cancel key K1, Fig. 1, when fully operated is held by magnet KL energized in a circuit including contact 68 and motor-operated contact 69, and a contact kl1 causes the counting-relay L to advance one step. The competitor key pertaining to the bet to be cancelled is now operated and this closes an independent circuit for the locking magnet KL. Relay F, Fig. 2, also is energized by a circuit through contacts 52, q1, resistance R3 and relay P in parallel, key contact 31 and line 32. The collecting switch now hunts as before and relays H, I operate. Relay I is effective on this occasion because resistance R1 is not now in its circuit and relay P has been shunted. Contact i1 opens to prevent relay W from operating and contact i4 closes a starting circuit for an interrupter. Contact i5 completes circuit for a relay J adapted to be short-circuited by the interrupter springs 55. The relay remains operated however by the action of contact j2 cutting out the short-circuit, this same contact closing a vibratory circuit branching and passing through the magnets of switches M, N and to relay Z (Fig. 3) all of which therefore advance or pulsate, the relay Z effecting through contact z1 corresponding stepping of duplicate counting-switch ND. When the cancelling-switch M has made nine steps, wiper m2 causes relay O to energize and by its contact o1 to break the circuit to switch N and relay Z, the counting-switches N, ND thus stopping after nine steps. Contact o3 however closes a self-interrupting circuit through wiper m2 and contact m1 to advance the switch M until the wiper reaches a contact unconnected with relay O. Owing to increased current in the line 32 due to the closing of contact o4, relay P at the transmitting- station now functions, and the ticket-issuing machine then operates as before and at the end of the operation the various circuit controls &c. are restored to normal condition. " Transfer " due to cancellation; competitor totalizer. If a counting-switch stands at nought when a cancellation operation is to be performed upon it, means are provided to reduce by unity the value standing on the next higher switch. When relay I operates as above described, a contact i3 and wiper n3 completes a circuit for a relay S which is then held by a circuit through control key K3. At s1 a circuit is now complete through relay U and resistance R6 in parallel, and line 43 to relay FA, Fig. 5, belonging to the higher denomination. This relay operates to cause the collecting switch GA to hunt and cancelling operations then take place as described above. When switch MA has advanced nine steps the current in line 43 increases so that relay U operates and consequently relay S releases. Cancellation of pool totalizer. When relay P, Fig. 1, operates owing to a cancel operation effected on the competitor totalizer, full earth potential is applied to line 28 leading to relay AP, Fig. 9. Switch GP hunts therefore as before but when line 28 is put in connection with relay CP this operates to close contact cp1 whereupon it fully operates over the contact ap5. Relays BP, DP are energized (the latter over contact cp3) when the switch finds the earth potential and contact dp1 prevents the closing of circuit to relay WP which would ordinarily occur owing to the operation of relay BP. Contact dp2 closes circuit to a relay JP, another contact causes the interrupter motor to run, and the operations previously described take place to advance the counting-switch nine places. A " transfer " due to cancellation when the counting- switch stands at zero takes place in a manner similar to that already described. Zeroizing. At the conclusion of betting, keys such as K3 (Fig. 2) and K4 (Fig. 9) are thrown t
