Patent GB-340280-A (GB)
Abstract: 340,280. Totalizators. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, LIMB, F., Holmwood, Fellows Road, and CANNELL, L. J., 84, Bramcote Drive, both in Beeston, Nottinghamshire. Sept. 21, 1929, No. 28644. [Class 106 (i).] The pool registration in a totalizator system is effected by a momentary impulse after the bet has been registered on the individual horse counter, the duration of the momentary impulse being independent of the time taken to effect its registration. Pool and individual horse bets are collected on receiving switches the wipers of which hunt to find markings to energize apparatuses, for example relays, other apparatuses, for example relays, also associated with the receiving switches releasing the first apparatuses when the bets have been registered and transfer, if necessary, initiated. Multi-denominational bets are simultaneously collected over different independent receiver switches transfer being by way of receiving switches of higher denominations. The transfer and the receiving- switch arrangements are also described in Specifications 340,288 and 340,289. General operation. The keys from a plurality of ticket machines corresponding to each denomination, are, for each horse, connected to a receiving switch adapted to hunt to find a lead marked by a depressed key, which when found advances a registering switch one step, actuates a horse total indicator and energizes a relay which releases the depressed key and marks a lead in a corresponding receiving switch of the pool totalizator which is then actuated. Horse receiving switch. Fig. 3, shows receiving switches ra2, rb2, rc2 for one horse corresponding to 2/-, ú1, and ú10 bets respectively. The banks of the switch ra2, say, are connected to multiwinding relays LA each winding being in circuit with a 2/- (units) ticket issuing key KA. Depression of a key KA only one of which may be operated at a time energizes one of the LA windings over contacts coal, a common relay CWA and resistance R1 in parallel, key KA, and marks the corresponding contact in the switch bank ra2. The current flow is insufficient to operate relay CWA but relay LA operates. The driving magnet RA energizes over interrupter contacts ra1 and contact la1, line 23 and switch ca1, Fig. 4. The wiper ra2 steps round under the control of its contacts ra1 until it finds the marked contact when a relay CA, Fig. 4 is operated over the wiper ra2, and lead 25. Contacts ca1 now disconnect the magnet RA and energize a relay CXA, which at contacts cxal energizes the driving magnet UA of the 2/- registering switch. Horse registering switch. The contacts cxa4 operate a relay SA over wiper ua4 (in normal position), and contacts sa6, which locks up over contacts sa6, lead 31 (dotted) and key KH, Fig. 10. The current now flowing through a resistance R2 and relays CA, LA in parallel is now sufficient to operate relay CWA. Contacts cwa1 operate a relay COA and the ticket printing and issuing motor JA the circuit for both being locked over double contacts coa1, which break the circuit through relays CWA, LA and CA, causing relay CXA and magnet UA to release the wipers ua2, .. ua9 being advanced one step. After issue of the ticket the motor JA releases the depressed key KA and then its cam CM releases contacts coa1 when the motor JA stops and relay COA de-energizes. If a key KA of another machine is depressed the wiper ra2 will hunt to find the corresponding marked lead and, as above, advance the registering switch UA another step. Monogrammic lamp indicator. The registering switch wipers ua6, .. ua9 energize relays A, .. E, Fig. 5, in various combinations according to their position to display numerals 0 .. 9 corresponding to the units registered by illuminating the appropriate lamps 1 .. 22, Fig. 11. The receiving switches rb2, rc2 Fig. 3, the registering switches, and the lamp indicator elements for ú1 and ú10 bets are similar to those for the units (2/-). If a ú10 bet is received before one of a lower denomination the indicator elements for these lower denominations are operated to display zero over leads 39 Fig. 4 energized over contacts sa3. Transfer. When nine units bets have been registered and the relay CXA has operated for the tenth a relay T is operated over wiper ua4 or ua5 and locks up over contacts t1 Fig. 9. Relay TR energizes in series with contacts t2 lead 41 Figs. 3 and 4, and a winding LB but does not operate as the current is insufficient. The relay LB actuates the " tens," ú1, receiving switch RB as for a ú1 direct registration, the relay TR operating to release relay T and itself when the ú1 registering switch magnet has energized and closed contacts corresponding to ua10. Transfer between the ú1 and ú10 counters is similar, but as ú10 is the highest denominational machine used, transfer to the ú100 and ú1000 counters is effected direct, the tenth contacts of wipers corresponding to wipers ua4, ua5, being connected over terminal 45 to a relay controlling, similarly to CA, the operating magnet of the next higher denominational registering switch and the relay actuating the lamp indicator. Pool counter ; receiving and registering switches; indicator. The pool receiving denominational switches RTA, RTB, RTC are connected to corresponding ticket machines over contacts cwa2, cwb2, cwc2 Fig. 3, lead 56 Fig. 7. When relay CWA operates, as above, contacts cwa2 close a circuit over lead 56, Figs. 3 and 7 contacts ya2, xa1 relay YA lead 57, Fig. 8, relay P. These relays operate, and lock up over contacts ya2. Contacts p1, p2 energize the driving magnet RTA over lead 58 Figs. 7 and 8, the wipers rta2, .. rta5 being stepped round under the control of the interrupter contacts rta1 until the contact marked by the contacts ya1 is reached. Relay CT then operates and at contact ct5 closes a circuit for relay XA over wiper rta2 or rta3. As contacts xa1 operate relays YA and P release. During the above cycle the switch RTA will not have time to complete more than one step, so that relays XA are connected to two successive steps of the banks rta2, rta3 to ensure operation. 'Contacts ya1 open and relay CT de-energizes, its contacts ct1 momentarily energizing the magnet UT the wipers of which are stepped once. If the contacts cwa2 are still closed when relay XA operates the latter will be held over these contacts until contacts cwa2 open, or normally until relay YA releases. This prevents a single impulse over lead 56 effecting two registrations. The relay P which is commoned to all relays YA from the various ticket machines, and thus at contacts p1, p2 stops the magnet RTA if no bets are waiting to be accepted, energizes, on its first operation a relay ST Fig. 8 which locks up over the reset key KH Fig. 10, and lead 63. This relay controls a lamp indicator as in Figs. 4 and 5 for the units of the pool total. Transfer is by way of wipers ut4, ut5, lead 69 and a relay YB of the ú1 receiving switch which actuates the ú1 pool counter similarly as the relay YA operates. Transfer to the ú100 and ú1000 registers is as for the horse registers the driving magnet of the ú100 switch say being energized by a relay connected to the terminal 68 Fig. 8 of the ú10 switch. Resetting. Depression of the key KH, Fig. 10, releases the indicator controlling relays SA, ST to extinguish the lamp indicators, the relay H closing at contacts similar to h1, circuits over resetting wipers similar to ua2, ua3 to the driving magnets of the registering switches of all the denominations for both horse and pool totals. The registering switches are accordingly stepped to zero by self interruption. Contacts cxa2, cxa3, ct2, ct3 to operate driving magnets similar to UA and UT are provided to actuate further indicators. For win and place bets the apparatus may be duplicated except the key KH and relay H which may be common to both.
