Abstract: 368,445. Totalizators. E R I C S SON TELEPHONES, Ltd., 67, Kingsway, London, and LIMB, F., Holmwood, Fellows Road, Beeston, Nottingham. Jan. 2, 1931, Nos. 160 and 11270. [Class 106 (i).] In a totalizator system, collecting means associated with a plurality of betting stations is adapted to assume only those positions corresponding to stations waiting to register bets. The collector comprises a relay chain, including contacts of relays associated with individual ticket issuing machines, the relays of operated machines only affecting the chain circuit. Each machine, Fig. 1, which caters for one stake value only, has associated therewith relay equipment (shown to the left of Fig. 2), multipled to common relay equipment (shown on the right of Fig. 2). The individual runner keys hl of all machines are connected by common lines, as 2, to jacks J, Fig. 3, the operative runner lines 2 being connected to the appropriate counting equipments by plugs P<1>, one denomination (win) and the corresponding denominational pool counter section being shown in Fig. 4. Starting operations. To commence betting, a key K1, Fig. 2, is operated, energizing a relay BS. Contacts bs1 close to energize the " chain " circuit from earth, through relay CT and resistance R1 in parallel, contacts bsl, st3, st<1>3, .., stn3, resistance R2 to battery. Relay CT operates and at contacts ct1 allows relay CF to energize over contacts bs4. A lamp Ll lights over contacts bs5, cf3. Relay TS, Fig. 4, in the pool counter operates over line 13 and contacts bs2, Fig. 2, and controls the pool indicator (not shown) at contacts ts4, Fig. 4. Keys K3, associated with the operative competitor adding equipments are now momentarily actuated, energizing corresponding relays IS which lock by way of contacts is5, bs2, and control the individual runner indicators over contacts is4, Fig. 4. Relays IT, and TT operate respectively over contacts is1, iql and ts1, tq1. Win betting. To enter a win bet, the winplace key K2, Fig. 1, is thrown downwards (where it is electrically inoperative), and the appropriate horse key depressed, closing individual runner contacts h1, and contacts u (closed by the operation of any runner key). Provided no other machines are waiting to make a bet, a circuit is made over contacts u, relay T, line 1, contacts ho3, ti2, and relay ST. Relay T does not now operate but relay ST operates, energizing a relay CD at contacts a1, st1. The individual connecting relay A operates in series with relay CT, Fig. 2, over contacts st3, pb4, terminal W and resistance RW, and locks over contacts ti4, c5, st4, a2 and its left-hand winding. Contact a6 earths the terminal W thereby preventing operation of any of the other connecting relays A<1>, .., A<n> associated with other machines from operating, if waiting to register win bets, although the chain circuit is maintained at contacts a3. Relay CD releases at contacts a1 unless held by the st1 contact of another machine. A circuit is now closed from earth, resistance R3, Fig. 2, contacts pb5, ho1, ti3, a9, line 4, runner key h1, Fig. 1, line 2, Fig. 3, contacts pa1 to operate an access relay WA, contacts of which, as wa3, Fig. 3, are associated with the various denominational sections of the win runner counter in question. A circuit is now made over contacts ti4, Fig. 2, c5, st4, a4, pb3, line 5, contacts tt1, Fig. 4, tz1, tr1, line 6, contacts wa3, Fig. 3, line 7, contacts it1, Fig. 4, izl, ir1 to energize a relay IM, which locks over its lower winding, contacts iml, lines 8a, 8, contacts pb7, a5, left-hand winding of relay TI contacts st7, c6, ti5. Relay TI operates and locks over contacts u, Fig. 1, relay T, line 1, and contact ti1 by way of its right-hand winding. The increased current in line 1 operates relay T, which initiates the ticket issuing operation in the usual way at the end of which contacts u, h1 and the key K2 relapse. Registering a win bet ; competitor and pool counter. Relay IM is also held over its upper winding by way of resistance R4, contacts im2, is2, idm1, and im3, ts2, tdm1. Contacts im5, im6 energize respectively the driving magnets IDM, TDM of the competitor and pool counters, breaking the locking circuits of relay IM at contacts idm1, tdm1 respectively. Contacts im4, wa2 maintain the terminal W at earth potential. Relay IM releases only after both counter magnets have pulled up and relay TI has operated to open contacts ti5, ti4. The counter magnets advance their wipers registering the bet, and relays ST, and then WA and A release. Ticket machine sequence operations. A hold-off relay HO is operated over contacts ti4, and if no other machines are waiting to make a bet, will relapse when relay TI falls off, but if relay CD is operated by another machine, relay HO holds over its upper winding contacts, c1, ho2 and cd1, thus preventing the machine, Fig. 1, from registering a second bet while other machines in the chain are waiting. Relay CD releases when no other machines associated with unoperated HO relays are waiting to register bets. Thereafter relays CD, HO release and contacts ho3 prepare the circuit of relay ST for further registration. If two or more ticket machines with associated HO relays operated are waiting to register bets preference is ultimately given to the machine having its associated st3 contact nearest to relay CT, similar preference being also given to waiting machines with unoperated HO relays. Transfer arrangements. When a tenth bet is being registered on the competitor counter section the lower winding of relay IZA, Fig. 4, is energized over wiper idm3 in parallel with driving magnet IDM. Relay IZA corresponds to relay IZ of the next lower denomination. Considering IZ ; when operated over its lower winding (as for IZA), it locks over contacts is3, iz2, ir6 and its upper winding. A relay IR now energizes over contacts iz3, im2, is2, idml and locks over contacts ir3, iz2, is3. Contact ir2 closes, to energize the driving magnet IDM. When IZ releases on both windings, the switch IDM advances and relay IR releases. Contacts iz4, ir5 for the lower denomination, function similarly to iza4 and ira5 for the denomination shown, to hold the relay IM when IZA is first operated. If for any reason contacts ira5 do not fall back after operation of the transfer, relay IM will be held when it operates for the next bet and further registration prevented. Transfer on the pool counter is similar, relays TZA, TZ corresponding to IZA and IZ. Relay TR corresponding to IR however, has two windings. It is operated over contacts tz3 and resistance R5 and locks over contacts tr3, ts2, and tdml the subsequent operation being as for the competitor counter. Place betting. To set up a place bet the win-place key K2, Fig. 1, is thrown upwards operating a relay PB, Fig. 2. Relays ST and A operate as before except that relay A is now fed over pb4, terminal P and resistance RP. Relay A locks as before, and contacts a6 apply earth to terminal P to prevent any other connecting relay A<1>, .. A<n> operating in response to a place bet. Contact a1 energizes a relay PD, Fig. 2, over contacts pb8. A circuit is now made over contact pd1, line 12, Figs. 2 and 4, relay PA, Fig. 3, contact wa1, line 2, key h1, Fig. 1, line 4, contacts a9, ti3, ho1, pb1, resistance R6, the current being in the reverse direction to that in the corresponding " win " circuit. Relay PA operates and subsequent operations are as for a " win " bet, the circuits of the IM magnet of the place adding equipment being over contacts pb3, pb7, lines 51 and 8<1>, and a contact of relay PA corresponding to wa3. The contacts pa2 earth terminal P similarly as wa2 earth terminal W. Ultimately the place bet is registered, relay PB releases after relapse of keys K2, h1, and relay PD releases after relapse of contact a1 unless held from another machine and disconnects relay PA. A win bet and a place bet on different runners may thus be registered simultaneously as the connecting relay operated for a win bet does not affect the operating circuit of a connecting relay for a place bet, and vice versa. Win and place bets made on the same competitor, however, are registered consecutively as relays WA and PA cannot both operate fully together. Modifications. A chain circuit with a WA and PA relay for each chain may be provided for each denomination, when two win or place bets in different denominations may be registered simultaneously. In this case, to prevent a bet being registered while a transfer is being effected to the same denomination contacts ir1, iz1, tr1, tz1 are included in the circuit of relay IM to prevent its operation. If relay IM is energized prior to or simultaneously with transfer relays IZ or TZ, the transfer is held up until the direct registration is effected. The common conductors 2, .. may be divided into groups, say, one for win bets and one for place bets, a relay chain circuit being provided for each group. Also, the apparatus may be alternatively adapted for concurrent win or place signals on different competitors. Cancelling bet entries. If a machine is operated for a win bet on a non-runner, the initial circuit operations are as before, but the line 2 is extended through the jack J and line 3 (a plug P of an adding equipment not being inserted in jack J) to operate a relay NW, Fig. 3. Contacts nw2 maintain earth on terminal W, Figs. 2 and 3, and contacts nwl extend earth from terminal NRW, Figs. 2 and 3, contacts pb2, a7, st5, relay C, contacts pb1, resistance R6. Relay C locks over resistance R3, contacts pb5, st2, c3, by way of its lower winding and contacts pb1. Closure of contacts c2, Fig. 2, lights a lamp L2 in the ticket machine, Fig. 1 ; contact c4 connects relays T, Fig. 1, and HO, Fig. 2, in series. Relay T does not operate, but HO operates. Relays NW, ST release owing to the relapse of contacts ho1, ho3 ; relay A is released at contact c5, and the machine operator seeing the la
