Abstract: 144,650. Julius, G. A. June 6, 1919, [Convention date]. Index type - wheel machines for printing tickets; platen-impression arrangements; web feeding and cutting arrangements; electric driving- mechanism.-Tickets for the totalizator system of betting upon horse races are printed, severed, and delivered by first rotating a setting-arm 67 into a position corresponding with the number of the horse selected and then depressing the arm so as to close a circuit to the central registering apparatus and to throw in a clutch for driving theticket-issuing mechanism. The central apparatus comprises a number of individual counters 21, 22, Fig. 15, one for each horse competing, and a grand totalizer 23, in circuit with the generator 20 and rotating contact maker 24 for momentarily closing circuits to the various ticket-issuing machines in succession. The individual counters are electrically connected with a series of contacts 79 arranged below and corresponding with numbered plunger holes 76 arcuately disposed and adapted to be engaged by a pin 74 on the arm 67. This arm is pivoted at 68 in a rotary bracket 69 containing a spring 73 tending to keep the arm raised. A toothed sector 81 secured to the bracket gears with a type wheel 60 which is thus set to present a number type agreeing with the number on the hole 76 selected. On depressing the arm, the spindle 72 connected to it rocks a switch arm 78 into engagement with the particular contact 79 above it and also through a rock shaft 103 removes a roller 100 on an arm 101 from engagement with the heel of a spring pawl 93 pivoted within a clutch box 92 fast on the shaft 91. A constantly rotating toothed plate 90 loose on this shaft is thereby clutched to the box wbich is thus caused to make one rotation, whereupon a gap 99 in the box again comes round and allows the roller 100 to disengage the pawl from the plate 90. During this rotation the roller 100 running on the periphery of the box prevents the arm 67 from rising and the switch arm 78 from falling out of contact. The box 92 is set and retained in the zero position when the machine is idle by means of a spring-controlled lever 96 having a roller 95 to engage a cam bay 98, Fig. 6. The box is provided with cam grooves 111, 120 for controlling the various operations as explained bellow. The ticket strip passes down a channel 41, Fig. 9, containing a tension regulator 42 and between platen and printing rollers 45, 44 and under a guillotine 53 controlled by a runner 122 in the cam groove 120. The strip is received in a cradle 58 which has side flanges provided with roller 174 supporting the ticket with its under surface free to be impressed by the type wheel 60. The cradle is lowered for this purpose by an arm 64 connected with a runner 123 in the cam groove 111. The cradle forms part of a carriage 62 pivotally attached to the arm 64 and guided vertically by a pillar 175. Within the carriage is a relatively movable block pivoted at 190 and carrying a pair of ejecting sectors 66 which are mounted on a spindle 183 and have arms 201, 203 provided with a spring 184 and a roller 182 respectively. When the carriage is descending, the roller 182 engages a fixed arm 181 and causes the block to rise somewhat about its pivot 190 and so allow the sectors 66 while travelling to the position shown in Fig. 13, to be clear of the ticket. A trigger lever 185 holds the sectors in this position and when the carriage commences to rise the sectors are first slightly lowered with respect to the carriage in order to grip the ticket and then by abutment of the trigger lever against a stop pin 188 they are released and under the influence of the spring 184 flick the ticket from the cradle into the delivery box. This latter consists of two compartments 35, 36, with a pivoted guide lip 147, which in one position allows the ejected ticket to enter the upper compartment for removal to the backer or issuer and in the other position guides the ticket into the locked compartment 36. When the machine is idle, the lip is in the latter position and is held there by an arm 151, Fig. 15, on its spindle engaging a pair of trip arms 153, 158. If the electric connexions have been completed and registration effected, the consequent excitation of an electromagnet 165 rocks an arm 163 which by a link 160 then moves the trip arms to release the arm 151 and allow the lip to take up the position shown in Fig. 9. The rocking of the arm 163 may also be effected mechanically when the machine is only being tested, as regards the printing and issuing of a ticket, by the engagement, in the " test " position of the setting arm 67, of a tappet 137 with a lever 136 connected with the arm 163. In order to keep the circuit closed until registration has been effected, a holding switch arm 141 is raised into action by the departure of the clutch box from idle position. A trip lever 169 in the idle position of the clutch box is engaged by a roller 170 so as to keep the latch end 168 raised from the contact with a lever 166 carrying the switch arm. As soon as the clutch box moves, the trip lever 169 is freed and under the action of a spring rocks and raises the switch arm into circuit-closing position. When the circuit has been completed at the central station and the electro-magnet 165 energized, the arm 163 rocks as before stated, the lever 166 is withdrawn from the trip lever and the switch arm falls. When the parts return to normal position the rollers 170 re-engages the trip lever and the latch end 168 wipes 'past the lever 166 and resumes its operative position above it ready for the next operation of the machine. Roller inking-arrangements.-The type-wheel 60 is inked by means of a roller 117, Fig. 6, which is carried by an arm 116 connected with a cam runner 112. and is held off the types during a part of its travel by means of a fixed rail 119.
