Patent GB-342276-A (GB)
Abstract: 342,276. Totalizators. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, Liverpool, and SIMPSON, L. M., The Bungalow, Laurel Bank, Stanks, near Leeds. Oct. 28, 1929, No. 32742. [Class 106 (i).] To enable a ticket-issuing machine of the onelead-per-runner type to be used with code signalling totalizing equipment, the connection of potential to one of the runner key leads is adapted to operate converting equipment which connects potential to the appropriate code signalling leads extending to the totalizing apparatus. The invention is described with reference to the coding arrangements described in Specification 331,500, [Class 106 (i), Calculating &c.]. The converting unit comprises a preselector switch adapted to hunt to find a lead marked by an operated runner key and thereupon to connect potential over one or more of its wipers to the code signalling leads. Runner key leads as 1 and 2 are connected to successive contacts of the bank of wiper 11 and through individual resistances as 3 and 4 to a common relay 5. Operation. When a runner key is depressed earth is extended to mark the appropriate contact of wiper 11 and also to operate the relay 5. The contact 6 of relay 5 extends earth to a relay 36 and over wiper 12 (in normal position) back contacts 8 to energize the driving magnet 19 which thereupon opens its interrupter contacts, deenergizes itself and advances the wipers 11 .. 18 one step. The magnet 19 is again energized and the switch wipers are stepped round until the wiper 11 reaches the marked contact when the relay 7 operates its contact 8 to open the driving magnet circuit. Earth is now extended from wiper 12, in off-normal position, over front contact 8, contact 34, relay 9 to wipers 13 .. 18, whence according to the multiplying of these banks, one or more of the code wires 21 .. 26 corresponding to the runner key depressed is energized. The decoding relays at the counting apparatus being in condition for registering a bet current will flow through the relay 9 to close contact 10 and operate the slow relay 33. Relay 33 locks up over contacts 35 and 6 and at contact 34 opens the circuit over the code signalling lead 21 .. 26, causing registration of the bet. Earth is now fed back from the counting apparatus over the ticket issuing lead 27. Relay 30 operates its contact 31 to close circuits initiating the ticket issuing operation during which the operated key is released, consequently releasing relays 5 and 7. The wipers are now homed, the circuit being from earth over wiper 12, in " on-normal" position, back contact 8 to magnet 19. Contact 6 releases relays 33 and 36, a momentary earth being connected to the lead 20 as the relay 36 is " slow." The cancellation lead 20 is, when an operated key does not lock, causing relays 5 and 7 to de-energize before the ticket-issuing operation is commenced, earthed before earth is disconnected from the signalling leads, thus avoiding a registration when no ticket is issued. Win and place arrangements. The above connections are for the runner win keys only. When a place bet is made, all the runner place keys or leads being commoned to a lead 28, earth is extended over this lead to a relay at the central station which switches over the signalling leads to a separate counter.
