Abstract: 339,278. Automatic Telephone Manufacturing Co., Ltd., Saxby, R. N., and Simpson, L. M. Aug. 21, 1929. Totalizators.-In a ticket machine for use in a totalizator system in which a plurality of keys determine the data, class of bet, runner number, and serial number, to be printed on each ticket, a type wheel bearing the runner numbers is rotated by means of an electric motor and is brought to rest in a position corresponding to the runner key depressed under the, electrical control of a brush rotatable with the type wheel. The " win." place " type is set by an electromagnet energized by actuating the appropriate key, and when a class and runner key have been actuated an electromagnet operates to cause a locking member to maintain the actuated keys depressed and prevents the operation of any other keys. The machine is described with reference to the system of Specification 331,500. Keyboard. This comprises a win, place, test, cancellation key, series of runner and value keys and a lamp indicator visible to both operator and backer. The depression of a win or place key and any horse runner key energizes a magnet which locks the depressed keys in their operated position, and the. remaining runner keys in their inoperative position. The series of value keys are provided with a separate but similar locking arrangement. Win and place arrangements. Depression of the win key energizes a magnet 99, its armature 100, through levers 102, 103, Figs. 5 and 8, rocking the pallet 104 pivoted at 105, when the right hand type corresponding to " win " comes beneath the printing hammer 109. Normally the place type is beneath the hammer. Operation of runner type wheel. The win or place and a horse key having been operated, circuits are made for the appropriate lamps on the key board, for an electric motor (not shown) geared to the shaft 36, and for the right hand coil 63 of a rnagnetic clutch shown in Fig. 7. The shaft 36 drives the central sleeve 43 of the clutch through gearing 39, 40 energization of the coils 62, 63 extending the motor drive to the gear wheel 50 and the shaft 51 respectively. Current is led to the coils by brushes, bearing on slip rings 71, the metallic casing 64 acting as a return path. The coil 63 being energized the shaft 51 is rotated and drives through bevel pinions 54, 83 the shaft 84, Fig. 6, integral with the type wheel 34 carrying variable data type corresponding to the various runners, and the shaft 79 carrying wipers 35 operating with contact banks as described in the above mentioned Specification. The type wheel is thus rotated until the control wiper reaches a contact corresponding to the runner key depressed when a relay, not shown, opens the circuit of the coil 63 and energizes the magnet 80 whereupon a pivoted trigger 81 engages a ratchet wheel 82 to arrest the type wheel in a position corresponding to the runner key depressed, a flat spring 98 having one end bedding into the ratchet wheel teeth being also provided. These operations when completed are denoted by lamps on the, key board. A value key, 2/- say, is now depressed causing, after the bet has been registered, energization of a magnet 111, Fig. 4, its armature 112 releasing the pawl 114 from the cam disc 115 integral with the wheel 73, and also energization of the coil 62 extending the motor drive to the gear wheel 50 which drives the gear wheel 73 in the direction indicated by the arrow, Fig. 4, independently of the energization of magnet 111, rotating the cam shaft 119 carrying cams 1 - - 4 which operate consecutively. The lever 120 is rocked when the roller 121 falls into a depression in cam 1 causing an arm 125 to turn and allow the hammer 109 to fall under the action of a spring 132 to press the ticket strip 135 mounted on a spool 136 against a carbon ribbon 137 and the variable data type. To obtain a clear impression the ticket strip is supported slightly above the carbon ribbon and the variable, data printed only in its centre, for about a third of its width. After cam 1 has lifted the hammer 109, cam 2 raises the roller 153 situated at the pivot (top end) of a lever 154 rotatable about its lower end, not shown, and also raises a lever 156, the lower end of which rotates the loosely mounted collar 158 which by means of its arm 157 and a spring pawl 160 advances the ratchet, wheel 161 one tooth. This movement, held by a. spring 167, and ratchet 168, drives, through a shaft 159 and gearing 162, 163, 164, the upper feed rolls 142, 149, which mesh with the journals of the lower rollers 140, 148, thus advancing the ticket strip and feeding one ticket out between the shear blades 189, 195. The lower feed rollers 140, 148 are eccentrically sprung to ensure perfect gripping of the ticket and as cam 2 operates, type on the wheels 140, 149 prints the permanent data on the outer portions of the ticket, the ink being conveyed to this type from a tray 144 by a pivotally sprung roller 141. To change, the permanent type the rollers 140, 149 are detached after the side plate 150, Fig. 5, is removed. Cam 3 next operates to advance the serial number mechanism by one. The roller 170 is lifted, the lever 171 rocking a sleeve 172, loosely mounted on shaft 124 causing a movement of a lever 173 and another 174 pivoted at right angles to it to operate a series of ratchets and pawls for advancing the serial number mechanism. The printing of the serial number is effected by the right hand side of the hammer 109 when the cam 1 operates but is made on the succeeding ticket. Cam 4. which operates at substantially the same time as cam 3, rocks through a lever 176, the shaft 178 causing the arm 179 to depress the head 181 and operate, the blade 189 to cut off a ticket which falls into a receptacle 196, Fig. 5. Cam 4 in rocking the shaft 178 oscillates a lever 198, the lever 199 pivoted at right angles to the latter, causing a pawl to advance a ratchet wheel 200 fixed to the shaft carrying the carbon ribbon spool 139. The cam shaft 119 has now completed one revolution, the end 114 falls into the notch 115 breaking. circuits at contacts 117 to stop the driving motor- and de-energize the coil 62 and the magnet 111 when the cam disc is locked by the pawl 114,. conditions being now ready for the issue of another ticket, the key locking magnets being deenergized to restore the depressed keys by a revertive impulse sent by the counting mechanism when the bet has been registered. If the 6/- key is depressed the above operations are. carried out thrice feeding three, separate tickets, or if desired the operation of cam 4 may be held up for example by lateral displacement of the lever 176 so that three, tickets are fed in a continuous strip, but in this case the carbon strip is not advanced. Moreover, if desired the magnet 111 could be energized to retain the lever 112 in "unlocking" position during the feeding of the tickets. Alternatively the driving motor, which is started at each ticket issuing operation, may be controlled by a timing device such as a dashpot, causing it to run for a short period following each ticket issued, so that when betting is heavy it runs continuously. Test and cancellation keys are provided, the former actuating a set of contact. springs for giving changes equivalent to the receipt of a revertive signal from the central totalizator equipment permitting the issue of a special ticket with a distinctive marking such as the word " test"; and the cancellation key being adapted to open the key locking circuit and to transmit a signal to prevent registration according to the wrongly set keys. Reference is made in the Provisional Specification to Specification 331,516.
