Patent GB-340508-A (GB)
Abstract: 340,508. Totalizators. HAMILTON, R. M., St. Andrew's Works, Slough. July 18, 1929, No. 22157. [Class 106 (i).] The invention consists in the insertion of hunter gears, comprising preselector switches, between bet impulse sending apparatuses and the corresponding counters. Master members corresponding to different horses are simultaneously set by the release of stored bets from ticket machines, the various follower members relating to each horse being adapted by means of horse-clearing switches interposed between the followers and their respective horse counters, to advance the individual horse followers successively to synchronism with their master members at the same time registering the bets on the individual horse meters. General lay out. A booth-selecting switch 11, Fig. 1 as in Specification 335,201, [Class 106 (i), Calculating &c.], successively energizes booths 12, 13, ... to release uni-denominational bets stored therein over individual horse contacts 14, 15, 16, 17, ... the corresponding relays 22, 23, 24, 25, ... stepping the master members 26, ... 29, ... respectively, accordingly. The follower element 30 and similar followers from other booth groups relating to the same horse are connected to successive contacts of a horse-clearing switch 37 which steps to successively synchronize these followers 30 with their masters 26 and to simultaneously actuate the individual horse counter 41. The horse counter may itself be a master member, its follower member 42 being interconnected with another similar clearing switch to actuate the pool counter or a sub-pool counter. A monogrammic lamp indicator 46 as in Specification 334,270, [Class 106 (i), Calculating &c.), displays the individual horse totals successively as switches 47, 48 are correspondingly stepped. Master member. The relay 22, Fig. 1 closes a contact 50, Fig. 2 for each bet impulse received and operates the driving magnet 51 to step the units master member 26 comprising banks 62, ... 68 accordingly. Tens and hundreds master elements identical with the units master element are provided, transfer being by way of bank 68 to bank 81 of the tens element, Figs. 2 and 3, there being no direct registration of bets higher than units. Follower member. The units element 30 comprises the banks 111, 112, ... 118. The banks 114, 115 are interconnected with the banks 62, ... 67 so that whenever the master element 26 is any number of steps up to nine in advance of the follower element 30 there is electrical connection between the lines 266 and 275 through the circuit shown within the chain line A this circuit being broken when both elements are in synchronism when a circuit is made from line 266 over circuit A to line 274. One bet corresponds to two contacts of the switch 30. Registration of bets ; clearing switch. The lines 274, ... 278 connected to the first contacts of the banks 174, ..... 178 of the clearing switch are connected as shown to points in the units element of the follower 30, the second and third contacts of the clearing switch will be connected to corresponding points in the tens and hundreds elements of the follower 30 subsequent contacts being connected to the units, tens, ... elements of other followers similar to 30. Assuming the master element 26 is in advance of the follower 30 and the clearing switch 37 is in the position shown a circuit is made from + ve wiper and bank 166, line 266, circuit A, line 275, bank 175, contact 375, bank 177, line 277, wiper 118, line 142 and interrupter contacts and driving magnet 160 of the units counting meter 41. The magnet 160 steps its wipers 166, 167 one step when circuit is now made from + ve, even contact of bank 166, line 278, bank 178, bank 176, lines 36, 276, odd contact and wiper 117, to the driving magnet 52 which now advances the follower 30 one step. The + ve on line 276 is now connected to line 376 even contact of a bank 111, line 143, even contact of bank 167 to advance the units meter 41 its second step corresponding to the registration of one bet, and the follower magnet 52 is now operated over lines 266 and 366 to complete the double step of the follower 30. If the follower 30 is still behind the master 26 the above operations recur the meter 41 advancing to register 1 bet for each 2 steps of the follower until the latter is in synchronism with the master 26 when + ve over line 266 is connected over circuit A, wiper 113, line 274 and bank 174 to energize the magnet 170 which steps the clearing switch on to its second contacts. The tens follower element Fig. 3 is now advanced to synchronism with the tens master element during which the tens metering element is correspondingly advanced, after which the clearing switch moves on to its third contacts to operate the hundreds follower element. The clearing switch is then stepped directly over the next contact (a blank one) to operate the next group of followers 30 and so on. Transfer. This is accomplished similarly between both follower and meter elements. When the follower 30 has completed ten double steps a circuit is made from + ve over line 121, odd contacts bank 137, Fig, 3, to step the driving magnet 130 of the tens follower when a circuit is made from + ve, bank 136, over line 123, bank 117 to operate the magnet 52. The tens magnet 130 is now energized over line 120 and when it has completed the double step of its associate banks energizes the units follower magnet 52 over line 122 to accomplish the double step of the latter. The follower is now stepped to normal, without any registration the last five contacts of the remaining banks of the follower being idle. Should bets be received on the master element 26 faster than the follower 30 can operate the latter might have to move more than nine steps for synchronism. To prevent this when the follower 30 passes the transfer point + ve from 213 over line 274 operates the driving magnet 170 to step the clearing switch whether synchronism has been reached or not. If a higher digit counting element, tens, hundreds, . . . . . , should be receiving a transfer impulse when it is initially connected to the clearing switch the latter is immediately stepped forward to the next group of followers. Thus, should the magnet 80 be actuated over the transfer banks 68, 81 when the tens master and follower elements are connected to the clearing switch 37 a relay K operates over line 273 and bank 173, and locks up over the bank 171, and contacts K<3>, the next succeeding impulses over the line 275 from the circuit A stepping the magnet 170 by way of contacts K<1>, K<2>. The relay K is released when the spare contact in the bank 171 is reached, the magnet 170 being operated to step on to the units element of the next group by way of + ve over contact 374. To prevent the switch 37 being thus stepped when the metering element is on an even contact corresponding to half a double step a contact K4 operated by the relay K just holds the magnet 170 operated until the meter has completed its double step when the clearing switch is stepped as before. Lines similar to 273 are provided for the tens, hundreds, ... of other groups connected to the clearing switch. Should the clearing switch be standing on a units meter when the master member of the latter is effecting a transfer the relay K would be operated over lead 273, bank 172 and resistance 372 sufficiently to operate only contacts K<1> and K<4>, the clearing switch passing on to the tens element which may now be cleared if the transfer has already been effected, and so on for other denominations. The Provisional Specification describes a modified form of metering apparatus and refers to Specifications 331,524 and 333,258, [both in Class 106 (i), Calculating &c.].
