Patent GB-351954-A (GB)
Abstract: 351,954. Electric totalizators. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. March 25, 1930, No. 9517. [Class 106 (i).] The ticket-issuing machines are grouped for the use of a common set of code-signalling lines and are individually connected (or assigned) one at a time with the lines, provided a bet is set up on the machine. Two or more such groups may be arranged and means provided whereby the different decoders may be put one after another into communication with the counters. The assigning means may take the form of relays or of selector switches. Ticket-machine arrangements, first form. At each ticket machine (A1 or B1, Figs. 1 and 3) there are a switching relay S and an assigning relay AS, a lock-out key LO and various lamps and contacts as stated later. The keys represented at HK are adapted to apply potential to the code lines A<1> . . F<1> in different combinations and a win or place key WP determines through lines w, p which set of counters shall be affected. The amount of the stake is set by one or more keys r2 connected with lines u, a, d, c, m serving to operate win or place relays SU &c or PSU &c., Fig. 2, and thereby divert the registering impulse accordingly at contacts su &c. psu &c. Decoding arrangements, Fig. 2. The decoding relays A .. F may be duplicated or triplicated as shown at DA or EB to share the multiplicity of contacts and operation of any of the relays completes circuit at contacts a1 .. f1 for a relay M which in turn closes a line through contact m1 and the decoding contacts to the win or place and value contacts of the competitor desired and thence to the counters. Operation. To start the betting a relay SB, Fig. 4, is released to close circuit at sb2, Fig. 3, to lamps sa, sa1 at the various machines. Assuming a win bet on horse No. 38 at machine A<1> the keys will be set accordingly and contacts MC1, MC2 automatically changed over. Relay ST is thus energized to operate a relay RE, Fig. 4, so that a line is closed at re1 through all the ticket machines. The negative on this line then causes energization of relay S to complete the key signal lines at s1 .. s8 and the decoding relays operate to send the bet signal to the appropriate counter which may be of the kind described in Specification 338,184, [Class 106 (i), Calculating &c.]. When the horse and grand total 1 counters have registered, a revertive signal is sent through contacts gtc1 and wc1, Fig. 2, to relay RA, line r, and contacts as3, s9 at the ticket machine to relay R. Consequently relay R breaks the signalling circuits at r2 .. r9 and the decoding and other signal relays relapse, at contact r1 the assigning relay AS is put in circuit with relay R, and the latter initiates the printing and issuing operation. The relay S is now de-energized by the movement of contact as1 which then continues the negative line to the succeeding machine. When ticket machine A<1> has completed its cycle of operation, contacts T1 open but relay AS remains energized being locked over its contact as4. If no bet has been set up on machine B<1> the contacts MC<1>1 will be at normal as shown and relay AS<1> will energize to continue the assignment line to the next machine. When the last machine of the group has been connected, the negative potential on the line energizes a relay RS, Fig. 4, at the central station to effect relapse of the relay RE and consequent breaking of the line at re1. To stop all betting operations relay SB is energized to prepare a locking circuit for relay RS which circuit is completed when the last machine has been assigned. Alarm arrangements. When a switching relay S operates, contact s11, Fig. 3, applies positive potential to a line to energize a relay SA, Fig. 4, self-locking at sa2, and prepare a circuit at sa1. Negative is applied to wires SPu and ZPu at regular intervals so that if after a predetermined time the relay S is not de-energized a relay ZA operates to complete at za1 a circuit to a lamp f or other alarm at the faulty machine. Alternatively the alarm circuit may cause operation of the relay AS at the machine so as to switch the assigning line forward to the next machine. Ticket machines, second form. Fig. 5 shows two machines A<1>, B<1> having switching relays S, S1 connected up with a bank as1 of an assigner switch. The machines contain other relays the functions of which will be described later. Decoding arrangements. These include a decoder assigning switch for the purpose'of putting the decoders of the machine groups in turn into communication with the counters. When a decoder has been assigned and cleared, the machine assigner of the group concerned operates to put the next machine into circuit and the decoder assigner steps to assign the next decoder. The decoding relays A .. F (FA, FB), Fig. 6, control corresponding relays adapted to lock up at a1 .. f1 ; otherwise the decoding system resembles that already referred to. The connection of the various decoders with the counters is controlled by the preselector switch AS\ Fig. 7, the bank as<1>1 of which is wired for five groups of machines (wiring connections for two only are shown). Operation. To initiate action, key WK, Fig. 7, is operated to prepare circuits for the win stake relays SU .. SM. Assuming a win bet on horse No. 38 at machine B\ the closing of master contacts M<1>1, M<1>2 energizes start relay ST and this completes a stepping circuit for machineassigning switch AS<1>. When the switch reaches the machine Bl, the relay S' becomes energized and completes the bet-signalling circuits at s<1>1 .. s<1>6 as well as other signal lines at s<1>7, s<1>9, and the win (or place) lines at s<1>8. The coded signal will proceed from contact M<1>1, relay T<1>, and the horse number keys to the decoder which then locks up. Relay T<1> causes relay BE to energize and lock up, and at be<1>2 the signalling circuit is then broken. Referring now to Figs. 6 and 7, the operation of relay M through relay contacts a2 . . f2 closes circuit at m4 to line r and the relay STB to complete circuit at stb1 through the interrupter contacts as<1>dm, bank as<1>1, contact m1, the decoding contacts and the pre-determined win and stake value contacts to the counters. If the switch AS<1> was not on the contacts corresponding with the decoder operated it would automatically step until the operated decoder is reached whereupon the circuit already traced through contact m1 would close. Relay SA now operated, due to contact m3, causes relay STA to lock up and prepare at sta2 a revertive signal circuit through line re. The revertive signal proceeding through wire u now advances the switch, thus breaking the bet signal circuit at asldm and bringing the next decoder into action. Bank as<1>2 breaks the circuit to relay SA to unlock the decoding relays at sa3 and effects at sa4 the application of potential to line re to operate relay R<1> at machine B<1>. An impulse is also sent over contacts m5, sta5 to the magnet ASDM to step the machine assigner switch to connect up the next machine. The operation of relay R<1> effects the start of the ticket-issuing operation and the restoration of the machine to normal. Alarm arrangements. If a bet is made on a non- runner a common relay CA, Fig. 6, is operated by the bet signal (the jacks WCSJ being no longer connected to the counters but to the relay) and causes at ca the locking-up of relay C and this in turn effects advance of the switch AS<1> and consequent relapse of relay CA. The contact c3 also diverts the revertive signal to relay RE<1> at the machine which consequently is restored to normal, and the next machine is then assigned. Keys are provided at each machine and for each decoder assigner to lock out the relative unit, and lamps such as A1, B1, Fig. 5, and GA, GE, Fig. 7, indicate the positions of the switches. Specification 340,298 also is referred to.
