Abstract: 441,422. Totalizators. TOTALISATORS, Ltd., Thames House, Queen Street Place, London.-(Julius, G. A. ; Culwulla Chambers, Castlereagh Street, Sydney, Australia) Oct. 25, 1934, No. 30654. [Class 100 (iv)] [See also Group XIX] In a ticket printing and issuing machine for totalizators having " number " and " class " printing - wheels, auxiliary type-faces are arranged on the sides of the printing - wheels to provide a check record of all issued tickets. The " number " printing-wheel is positioned by a selector-lever and the " class wheel by a radial movement of a member arranged slidably within said lever. As shown in Fig. 4, a selector-member 30 is slidably mounted in a sleeve 35 which is pivotally mounted so as to be rotated over a dial plate 63 provided with a number of dialling holes 66 corresponding to the horse numbers. The " class " (win or place) printing-wheel is set in accordance with the radial position of the member 30 and the " horse " wheel is positioned by the rotation of the member 35. When set, printing operations are initiated by plunging the member 35 downwardly to engage 89 in the appropriate horse aperture 66. When the selector-member 35 is moved over the dial plate a switch 67 is simultaneously carried round by the members 70, 88 to select a circuit appropriate to the horse. The switch 67 may be positioned on one or other of the banks of contacts 31, 32 according to the position of the slidable member 30. When the member is moved inwardly the bellcrank 77 operates a rod 79 downwardly to raise the switch 67 into contact with the "place" bank 32. Outward movement of the member 30 lowers the contact into engagement with the "win" bank 31. The integrator circuits selected over the banks 31, 32 are not completed until the selector-lever 35 is pushed downwardly, the movement being communicated by a bush 90 to a sleeve 91 which rocks.a lever 93 without affecting the rod 79. The lever 93 trips a spring-controlled switch 38 which initiates the integrating and printing operations. When tripped the switch locks the lever 93, the sleeve 91, and member 35 in the plunged position. At the end of the integrating and printing operation, a cam opens the switch and allows the parts to restore under the control of a spring 101. When the member 35 is rotated over the dial plate, a horse-number printing-wheel 109 is positioned through gearing 106, 107. The " class " sector wheel 110 Fig. 10 is freely mounted on the shaft of wheel 109 and is positioned by a link 118 connected to a shaft 115 which is rocked by a lever 114 connected to the rod 79. The shaft 115 also controls a switch 44 which selects the win " or " place " integrators or a " test " circuit. Following the plunging of the member 35 and operation of contact 38, a clutch-member is operated to drive a main shaft 124. The shaft 124 carries a cam which operates a pawl for locking the printing-wheel 109 and also a cam disc 181 which operates a steel band 182 pivoted at 183. The band is fixed to an oscillatory drum 184 which is rotatable on a shaft 185. A flexible wire 188 attached to the drum passes over a pulley 189. While the pin 183 is moving upwardly the drum 184 rotates idly on shaft 185 but during the downward movement of the pin the drum operates the shaft through the ratchet-gear. The shaft drives through gearing the rollers carrying the ticket strip, and a strip 127 for recording the checking indications together with the ink ribbons so that the arrangement provides for an intermittent stepping forward of the strips and ribbons. The ticket strip 128, Fig. 5, is fed forward by a roller 130 on the shaft 185 and is led beneath a platen 116 to the guillotine 132 and delivery shoot 133. The second check-strip 127 is drawn from a spool 137 under a platen 138 and on to the spool 141 The ink ribbon 142 of the check strip is drawn from spool 143 on to a roller 144 driven from the shaft 185. Prior to the stepping operation of the strips, i.e. during the upward movement of pin 183, the printing operation is effected. A cam 152 on the driving shaft 124 oscillates a lever 153 pivoted at 156 and carrying a pin engaging a slot in a bell-crank lever 157, also pivoted on 156. The spindle 156 is held in its bearings by springs which may be moved to facilitate removal of the spindle. The lever 157 carries the platen 116 and when lever 153 is oscillated, the crank 157 is rocked and the platen lowered to effect printing. A cam 170 operates the platen 138 to produce a check record on strip 127 from type which is arranged on the side of the main printing wheel 109. A second " class " segment 126 has its type also arranged on the side so as to co-operate with the check record. In addition to the records already mentioned several numbering-stamps 165, 178 which are stepped forward at each operation are provided. A stamp 166 containing further information also is provided. The " horse " number selecting-means is arranged in its extreme position to facilitate testing. When the member 35 is moved into that position, the printing-wheel is moved correspondingly and a pin 233, Fig. 10, engages a pin 232 on the " class " printing-sector 110 to position the " test type under the platen. Movement of the " class " sector also operates switch 44 on to " test " contact 60. A pin 231 on the locking-plate of the main printing- wheel also prevents operation of a counter which records the totals of both " win " and " class " operations. After the " test " printing operation, the spring 119 restores the printing wheels to normal position the switch being restored by link 118. The switch 46, Fig. 12, which changes the circuits from integrating to printing comprises lever 243 operated by the armature of a magnet 47 and carrying a finger 245 which coacts with a finger 246 on' the blade 46. The blade 46 is articulated to a bell-crank 250 which is operated by a cam on shaft 124. When the magnet is energized, the lever 243 is lifted clear of the finger 246 and the blade is swung into engagement with contacts 50, 51 by a spring (not shown), thereby opening the integrator circuit and closing the clutch circuit. The cam 251 is then driven and the bell-crank 250 is rocked against the tension of spring 256. The pivot 249 is thus moved to the right and the projection 246 is moved away from 245 to allow the latter to fall in front of the projection. When the bellcrank 250 snaps off the cam, the spring throws over the blade on to contacts 247, 248. Fig. 11 shows the circuit arrangements. When the lever 30 is positioned and plunged, a series circuit is completed for the appropriate " horse " integrator and the " total " integrators in one or other of the groups W, P according to the bank 31, 32 of contacts selected. Included in the circuit is the trip magnet 47 which when operated throws over switch 46 to energize the clutch 24. Ticket printing operations then take place and subsequently the switch 46 is restored as previously described. Specifications 297,048, [Class 100 (iv)], and 414,279, [Group XIX], are referred to.
