Patent GB-348515-A (GB)
Abstract: 348,515. Totalizators. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, and BELAS, F. T., 24, Stanley Street, both in Liverpool. Jan. 31, 1930, No. 3424. [Class 106 (i).] In an electric totalizator system in which bets of low value are stored on a step-by-step switch but not normally displayed, these bets totals are displayed at the end of betting on apparatus controlled automatically by the step-by-step switch. A stored units collecting switch rotates automatically at the end of betting on a race to transfer bets from the lower value storing switches to a corresponding counter which adds these values to the normal display indicator. The invention is described with reference to Specification 342,261, a 2/- storing switch replacing the storage relays while the operation of the stored units collecting switch is modified. Storing switch, 2/-. A marking over a 2/- wiper of the collecting switch HCS (Fig. 6, Specification 342,261) extends to the line 67, contacts uy2, uz2, and bank 2 of a 2/- storing switch STS, contacts sr of the interrupter relay SR (Fig. 6, Specification 342,261) interacting with the horse collecting switch driving magnet HCM (Fig. 6, Specification 342,261) to energize the relay IA. Contacts ia1 extend earth over lead 70 to hold the magnet HCM energized, contacts ia2 connect battery by way of the lower low resistance winding IA to lead 67 to initiate the ticket issuing operation, contacts ia3 energize the driving magnet STM of the switch STS, contacts ia4 lock up the relay IA over contacts stm, ss1, the relay SS being energized by depression of the start key of the individual adding machine. The interrupter contacts stm open and providing the revertive signal over lead 67 has initiated, the ticket issuing operation earth is disconnected from this line and relay IA deenergizes, contacts ia3 opening to step the banks 1, 2, 3 of the switch STS on to their second contacts, the switch being similarly stepped on the reception of succeeding bets. Storage relays. When the tenth bet impulse arrives to operate relay IA earth is extended over contacts ss5, wiper 3, contacts ia5, line 17, contacts uy3 to energize a two-step storage relay UY. The latter operates its light armature uy1 and when the switch STS advances, consequent on relay IA de-energizing, relay UY operates fully over both windings in series and contacts ry6, uy1 to earth on lead 16. The reception of the twentieth bet will operate similarly a storage relay UZ over line 17 and contacts uy3, this relay locking up over contacts rz6 and uz1. The switch STS may make another seven steps corresponding to a total of twenty-seven bets stored, when the circuit to the impulsing relay IA is broken over wiper 2 and the switch STS comes to rest on its eighth contacts, thus preventing the horse collecting switch from forwarding any more bet signals. Translating switch. In periods of normal betting the energization of relay UY marks the sixth contact in the bank 2a of the translating switch TP, and extends earth to the conductor 78 (common to contacts rs5 of relays RS associated with all storing groups) over contacts uy7. The remaining contacts of the banks 1a .. 4a are similarly wired to other 2/- storing groups and to two 10/- storing relay groups. If the translating switch does not rest on its sixth contact, and, assuming the UY relays of the other groups are not operated, a circuit is now made from earth on line 78, contacts rs5, and contacts uy6, ry3, of unoperated groups, to energize the driving magnet TPM which steps by self-interruption until the wiper 1a reaches an unmarked contact, in this case the sixth. The operation of the translating switch is now similar to that described in Specification 342,261. The earth over contacts uy6 and lead 80 upon the next operation of the interrupter relay SR energizes a relay CG (Fig 13, Specification 342,261). The driving magnet HCM is now held energized and relay CG operates in series with a relay CZ (Fig. 13, Specification 342,261). Relay CZ applies earth over lead 83, contacts rs2, uy4 to operate a relay RY. Contacts ry6 open the locking circuit of relay UY and contacts ry5 extend earth over wiper 4a, line 86 operating a relay CR (Fig. 13, Specification 342,261) which provides a locking circuit over line 83 for relay RY, opens relays CG, CZ and energizes the driving magnet of the ú1 counting switch, the interrupter springs of which now open the circuit over line 83. If relay UY has released, RY will now release, and contacts ry5 will release relay CR, which, if CG and CZ have restored, will also restore, advancing the ú1 counting switch, when conditions are restored to normal. During heavy betting periods twenty-seven bets may be stored before the switch TP is freed from other groups to translate the stored bets. In this case two impulses are sent over the translating switch wipers, the relays UZ, RZ being similar to UY, RY, the impulsing circuit to relay IA being closed when either UY or UZ is released, enabling the storing operation to proceed. The connecting relay RS is de-energized on the ninth and tenth contacts of STS but should a transfer be in operation as STS is stepped to its ninth contact, the relay RS is held over contacts ry7 or rz7 until the operation is completed. The relays UY and RY may be dispensed with, when a maximum of only seventeen bets can be stored on STS. Stored units collecting switch. The leads from the banks 3 of the various 2/- storing groups are connected to the wipers 8b, 4b, 7b, 3b of the stored units collecting switch SUC, Fig. 3, seven group connections being shown, as well as contacts aa, ab of two 10/- storage relay groups. When betting has finished the main control key is depressed removing earth from line 52 releasing relays DA and MS. DA may however be held over line 78 until the translating switch TP has completed its function. Contacts ms1 .. ms3 bring their corresponding collecting switches to rest. A relay IR is now energized over contacts da1, db2, wiper 5b and contacts sum, and interacts with the driving magnet SUM to continuously step the switch SUC. At each energization of relay IR an impulse is sent over contacts pc2, ir1 to step the 2/- counting switch until the wiper 8b reaches the contact in the first 2/- group marked over contacts ss5, Fig. 1, by the wiper 3 when a relay PC is operated over contacts tw3, da3, and locks up over contacts pc1 to earth on line 51, opening contacts pc2. The switch SUC is now stepped over the remaining contacts of the group when a relay PR is operated over contacts pc3, da3, tw3, ir2. This relay breaks the locking circuit of relay PC so that when the wiper 8b passes over the next group contacts, impulses are again sent to the 2/- counter over contacts pc2 until the contact marked according to the units stored on the corresponding group switch STS is reached when relay PC is again operated. The stored units of the first four groups are thus transferred to the 2/- counting switch. When the switch SUC has made a revolution, relays ON and TW interact and the switch is stepped for a second revolution, leaving relay TW operated, relays ON and DB being released. Contacts tw3 connect up the wipers 7b, 3b so that the bets stored in the remaining three 2/- groups are registered. When the wiper 3b reaches the contacts connected to the contacts aa, ab respectively, the relay PC is energized on the first contact of each group, if the corresponding 10/- storing relays are at normal, whereas if the contacts aa or ab are operated signifying a stored 10/- bet five 2/- impulses are registered over contacts pc2 for the appropriate group. When the second revolution of switch SUC is completed no further circuit is made for the driving magnet SUM and relay TW releases, when the apparatus is at normal.
