Patent GB-201152-A (GB)
Abstract: 201,152. Setright, H. R. July 20, 1922, [Convention date]. Tickets, issuing and cutting-off; printing-arrangements; checking receipts. - Recording and totalling mechanism is electromagnetically connected to a ticket-issuing machine so that it is impossible for the machine to print the distinctive numerals, letters or characters distinguishing an authentic ticket until the recording and totalling mechanism is operated. The arrangement is shown applied to a totalizator but may be used for ticketissuing machines for railways, theatres, &c. A constantly driven pulley 32<a>, Figs. 1 and 4, actuates a shaft 23 through a friction grip, a sprocketwheel 32 on the shaft driving through a chain 24 on a sprocket wheel 33 on a shaft 34. The shaft 34 carries a platen roller 38 and a gear-wheel operating type, platen, and inking rollers for printing the permanent matter upon the front and obverse sides of the ticket strip as it passes from the entrance slot Z to a guide slot 150. The strip then passes between a platen 81 and selective printing members 57, 133. The member 57, in the form of a disc, is secured to a sleeve 60 that extends into a recess in a push handle 25, Fig. 9. The handle, which is splined on the sleeve, is rigidly mounted on a shaft 62 extending through the sleeve and provided with a projection 63 at its far end. A disc 84 carrying a number of contacts 85<a> and terminals 85 is arranged behind the member 57 which mav be rotated bv the handle 25 to bring any selected printing member 56 below the platen 81 the operator being guided by an indicator 50 attached to the handle moving over a number plate 28. The member 57 carries a spring-pressed sliding bridge-piece 147 adapted to complete an electrical connection between anyone of the contacts 85<a> and a conducting strip 86 let into the member 84. After the desired member 56 has been brought under the platen the operator, by pushing in the handle 25 against the pressure of a spring 59 above the sleeve 60, presses the projection 63 at the end of the shaft 62 outwards permitting a hooked arm 95 on a lever 94 to move off this projection and thus bringing a contact-plate 101 carried by an arm 95<a> of the lever 94 against contacts 90, 91. The circuit for an electromagnet 102 operating the platen 81 is thus completed and the ticket is printed by the selected member 56 on the disc 57 and by the desired type 133 on a hand-set disc 132. This circuit is completed through the bridge-piece 147 which connects the terminal 85 corresponding to the selected printing-member to the conducting strip, each terminal being con. nected through an individual totalling machine 202, Fig. 10, to one of the mains. The disc 84 carries one terminal 85<b> for test purposes, this terminal being adapted to be connected to a contact stud 88 by the bridge-piece 147 when the indicator is moved over the plate 28 to the test position : the operator also moves a double pole switch 205 to the position shown in Fig. 10. The test circuit is completed from 204<a> through lead 215, switch 205<a>, lead 210, automatic switch 155, electromagnet 102, lead 208, terminals 91, 90, (bridged by contact-plate 101 when pushhandle 25 is depressed) lead 211, switch 205<b>, lead 213, test stud and terminal 88, 85<b> and lead 204. For normal working the switch 205 is thrown over to its other pair of contacts and the circuit from 204<a> is then completed through a grand totalling machine 203, a rotary distributor 207 for connecting up other ticket-issuing machines to the individual totalling-machines 202 and grand totalling machine 203, a relay rod 206 and lead 214. The armature of the electromagnet 102 is provided with an extension 103<a>, Fig. 7, that carries a cam 115 adapted to engage a roller 114 on a lever 113 provided with a hooked stop 111 to engage projections 109 arranged at equal distances round the circumference of a ring secured on a gear-wheel 105 which is driven from the shaft 34. The ring is provided with similar internal projections 108 adapted to be engaged by a stop on a lever 27 to which is secured a bar 118 having a bifurcated upper end in which the extension 103<a> of the armature moves. The levers 113, 27 are normally pulled' towards each other by a spring 121. the stop on the lever 27 engaging one of the projections 108 and the stop 111 being lifted from the ring by the roller 114 engaging the cam 115. On the armature being actuated through depressing the push-handle the lever 27 is pressed away from the ring and the lever 113 freed to bring the stop 111 into position to engage a projection 109. Immediately the lever 27 clears the projection 108 the gear wheel 105 begins to rotate under the drive from the pulley 32<a> transmitted through the friction clutch to the wheel 32 and the shaft 34 : after moving a short distance the wheel is stopped by the stop 111 engaging a projection 109 but on the armature rising again the stop is lifted and the gearwheel moves through one-third of a revolution when the lever 27 engages the next projection 108. The wheel 106 meshing with the wheel 105 moves through half a revolution in the same period and operates the printing mechanism for the permanent matter upon the next ticket. A gearwheel 124, Fig. 3, also in mesh with the wheel 105, simultaneously operates a delivery roller 122 resiliently engaging two rollers 123, 123<a> to deliver the completely printed ticket. The lever 27 projects through the casing and may be operated by hand to feed a new strip through the machine a link M being moved in this case to cancel any tickets issued by pressing an ink roll Q<1> against them. An ink-ribbon 73 is fed over the printing discs by a bevel-wheel 77 on the shaft 23. A type-roller 40, Fig. 9, positively driven from the shaft 34, carries a cam 96 adapted to engage an extension 94<a> of the lever 94 carrying the contact plate 101. After the push-handle has been depressed the end of the hooked arm 95 drops behind the projection 63 of the shaft 62 and prevents the handle being withdrawn until the hooked arm is raised again by the cam 96 lifting the lever 94. Should the push-handle be depressed when the indicator has been set to a terminal for which the circuit is not complete, for example to the terminal corresponding to the number of a horse that has been scratched, the armature fails to move, the gear-wheels are not freed and the arm 95 remains at the back of the projection 63 holding the push-handle down and thus drawing the attention of the attendant to the error : a manually operated plunger 26 is provided to operate the lever 94 under these circumstances and so to raise the arm 95 above the projection 63. The printed ticket is cut off by a guillotine blade 192, Fig. 4, secured by a bar 193 to the electromagnet armature 103 and pressed outwards by a spring 197 against a co-operating knife on the frame. The blade 192 and the armature are raised after the strip has been cut off by a spring 198 secured to a yoke across the frame and to a pin 196 projecting from the bar connecting the platen 81 to the armature. The guillotine blade may be omitted and a knife 130 attached to the delivery opening 31 of the machine against which the strip may be torn off by hand. The circuit through the totalling machines is automatically broken by the movement of the armature operating the selective printing means. An extension 103<b>, Fig. 5, on the armature car- .ries a bifurcated bar 178 engaging a pin 177 on a latch 176 holding a spring-pressed lever 153. The lever carries a contact member 161 connected by a spring 163 with a terminal 162 and normally in contact with an adjustable pin 172 on a bellcrank lever 166 the other arm of which engages a cam 151 on the shaft 34 under the pressure of a spring 168 : the pin 172 is connected by a spring 174 with a terminal 173. When the armature descends the latch is lifted and the lever 153 turned counterclockwise opening the switch : the shaft 34 then begins to rotate pressing back the lever 166 bv the cam 151. As the shaft 34 moves through half a revolution a second cam 152 engages a roll 182 on the lever 153 and pushes back this lever under the latch again. On the completion of the half-revolution the shaft stops as previously described, the arm of the lever 166 entering a recess in the cam 151 thus bringing the pin 172 into contact with the member 161 again. The armature extension 103 also carries a bar operating a mechanical counter 30, Fig. 3.
