Abstract: 21,686. Thompson, W. P., [Temco Manufacturing Co.]. Sept. 24. Tickets, holding and issuing. - The ticketroll is supported by a pin 14 mounted in a casing comprising side plates 4, 8, 5 and a top plate; and the issuing device is housed between the plates 4, 8, a band 11 being provided to fill the space between the plates 4, 8. The strip is divided into ticket portions by notches 21 and perforations 22, in which engage teeth 23, Fig. 6, on the feeding- drum 24 carried between the plates 8, 5 by a shaft 27 passing through all the plates. The tickets are fed through an opening 25, and the strip is held taut by a roller 29 carried by a spring-controlled bell-crank lever 31 mounted on the pin 14, a brake 18 being provided to press on the ticket roll. Rotation of the feeddrum 24 is derived from a sprocket-wheel 47, Fig. 5, secured to a ratchet-wheel 44 mounted on the spindle 27, the ratchet-wheel being engaged by pawls 48 which are carried by a wheel 39 secured to the hub 26 of the drum 24. Notches 40 in the wheel 39 are adapted to be engaged by a non-return pawl 41. Movement of the wheel 39 is prevented unless the projections 52 of the pawls are fully engaged with the ratchet teeth by a spring-controlled disk 53 notched at 56 to correspond with the ratchetwheel teeth and mounted by slots 57 and pins 55 concentrically with the shaft 27. Projections 61 are provided on the pawls to engage the notches 56, and, unless removed therefrom, the wheel 39 is prevented from moving beyond the limit of the slots 57. The plain edge of the ring 53 serves to lock the pawls in the engaged position. The chain producing the rotation of the wheel 47 is secured at one end to a pin 82 on a spring-retracted sliding plate 62 and passes over sprocket-wheels 88, 91, 94, Fig. 2, to a spring 100 carried by the casing, the spring 100 being weaker than the spring 81 of the slide 62. The wheel 91 is carried by a slide 93 capable of being depressed by a pedal, and when so depressed, the spring 100 stretches and allows the ratchet-wheel to rotate until the pawls 48 fall into engagement and the wheel 39 is locked by the plate 62 preventing the upward movement of the pawl 41. Further downward movement of the pedal moves the plate 62 against its spring and thus frees the pawl 41 and also opens the slot 25 through which the ticket is fed. Removal of pressure from the pedal allows the parts to return to their original positions, the zero position of the shaft being determined by an arm thereon engaging a stop on the casing. Means are provided on the shaft 95 of the wheel 94 for limiting the feed of the ticket-strip, and a knife for severing the tickets is actuated on the return of the plate 62. The ticket-strip is held in engagement with the feed-drum by one or more rollers 154, Fig. 6, mounted in slots 156 in a pair of plates 157 which are pivoted on a rod 158. A spring 161, secured to the axle of the rollers and to a pin 160 on the frame, serves to press the rollers down and raises the frame 157 against a pivoted plate 78, which may be turned aside to allow adjustment of a new ticket strip. When the last ticket has been fed the drum is locked by a projection on a spring-depressed pivoted plate 163, shown in dotted lines in Fig. 6, engaging one of a series of notches 166 formed in the drum, a roller 169 carried by a second plate 167 serving to hold the last ticket in position. The operating-slide 93 may be locked by a bolt 200 adapted to engage a shoulder 194 on the slide, a spring catch 206, which may be released by a key, being provided to prevent unauthorised return of the bolt. The tensioning arrangement for the ticket may be replaced by that shown in Fig. 10, in which the strip passes round a roller 227 carried by an arm 229 pivoted at 230 to a bell-crank lever 231 mounted on the pin 211 carrying the ticketreel. A pin 238 on the arm 239 of the lever engages a slotted link 235 which is pivoted to the operating-slide 93 and is connected to the arm 229 by a spring 240. When the slide is depressed, the roller 227 is lifted, thus loosening the strip and allowing it to be drawn off freely by the feed-roller. On the return of the slide, the lowering of the roller 227 draws off a further supply into the loop 226, quick return of the operating-slide being allowed for by the slot 237 and the spring 240. A roller carried by a spring-depressed bell-crank lever is provided to brake the ticket-roll. Registering number.-A counter 171, Fig. 6, is operated by gearing 176, 175, 173 from the hub of the drum 24, and, to prevent tampering, a hinged cover is provided which is held closed by a lock.
