Patent GB-231507-A (GB)
Abstract: 231,507. Brightwell, W. F. March 26, 1924, [Convention date]. Tickets, issuing.-In a power-driven ticket issuing machine for use with totalizators, the selective device by which the machine is con trolled is adapted to complete circuits which actuate the individual and grand totalizers, and cause an electric motor to drive the mechanism which prints and partially severs the ticket, an automatic device then altering the circuits so that the motor continues in action until the printed ticket has been delivered. A testing circuit is arranged so that the machine may be operated without actuating the counters, tickets issued during such operation being marked " test." The selecting device comprises a marker disc 28 whch is slidablv mounted on a shaft 24 which also carries the printing wheel 26. A block on the selector is fitted with a locating pin 39 and electric contacts 40, 41 connected by a bridge-piece 42 and adapted, when the selector is moved axially, to contact with spaced studs 44 and a ring 43 mounted on a fixed disc 27 of insulating material. The selector 28 is locked by a lever 64 which engages a recess 37 and' is tripped after an interval bv a connection with a motordriven part. Fig. 13 shows the arrangement of circuits. Two contact-making bars 103, 167 mounted on pivoted levers 92, 155 are arranged to bridge alternate pairs of contacts, the lever 92 being rocked by an electromagnet 105, and the lever 155, after an interval, bv mechanism driven by the motor 110. In operation, when the selector disc 28 is positioned and pushed in, the contacts 40, 41 complete a circuit through the ring 43, one of the contact studs 41, and an individual counter 269 corresponding to the setting of the disc 28. A grand totalizer 270 is also actuated and a distributor as described in Specification 233,702, [Class 106 (i), Calculating &c.], is provided. The electromagnet 105 is energized, and the bar 103 is shifted to bridge the lower contacts and so switch in the driving motor 110. This motor, which is mounted on the underside of a table 20, Fig. 1, drives a shaft 125, Fig. 3, carried in bearings on the upper side of the table, through gearing 117, 122, 124. An eccentric 130 on the shaft 125 actuates the printing platen and the severing knife, and an arm 129 engages a star-wheel 132 on a shaft 136 by which the ticket-strip is fed and the motor is automatically stopped. The strip feeding rollers 179, 181 are driven by gearing from a toothed wheel 137 on the shaft 136. A cam 139 secured to the gear 137 is arranged to rock the lever 155 through lever 159 and link 161 and so make and break the circuit which controls the running of the motor 110 during the second part of an operation. A shaft 140 driven by gearing from the shaft 136 is provided with a stop-disc 142 cooperating with a lever 149. This lever also serves to release the latch 84 which locks the lever 92 of the electromagnet 105 during the first part of an operation. A mechanical counter 237 is actuated by a pin 256 on the gear 124 at each operation of the machine excepting during a test, when it is rendered inoperative by a link 247 which is actuated by a roller 245 engaging a projection 212 on an appropriate part of the printing- wheel 26. The testing circuit is shown by the lines 279, 280, Fig. 13. Printing-arrangements.-The printing platen 133, Fig 9, is mounted on pivoted spring-pulled arms 190 and is depressed against the type wheel 26 by an eccentric 130 on the motor-driven shaft 125. The ink-ribbon 134 is wound on a roller 219, Fig. 1, which is driven by the shaft 182 of the strip-feed roller 181. The worm 224 in the drive is slidably mounted to allow for re-winding of the ribbon. In addition to the printing-wheel 26 which is positioned by the selector 28, a printing disc 26<a> having other type on its periphery is provided. This disc is set by a knob 264 through gearing 49, 59 and may be used to print the number of the race. Tickets, cutting-off.-The severing knife 202 has a gap 216 in the centre so that it does not completely sever a ticket. It is actuated by a pin 200 on the printing platen engaging a hole 201 and its movement is restrained by pins 213 and springs 206.
