Abstract: 19,739. Engelke, W., and Cornish, P. Aug. 29. Index type-wheel machines with printing- surfaces for tickets.-A ticket-printing machine of the kind in which the operations are registered on electrically-operated counters, comprises a plunger a which is turned to set a typewheel l and is then pushed axially to impress the type on the ticket-strip t, the impression mechanism being arranged to operate devices for feeding and cutting the strip and to close contacts for the counters. The typewheel l is preferably in the form of a polygonal block bearing types l<1>, l<2>, l<3> which in some cases are adapted to emboss or perforate the ticket so that its value can be told by touch. The type-wheel is journaled in a cross-head e and is connected by bevel-gearing m, m<1> to the plunger, the cross-head being mounted to slide on pillars f. The cross-head also carries a surface p for printing the name of the place of entertainment &c. and a series of dating-wheels n. The plunger is provided with a knob b bearing marks corresponding to the types, the required type being set by turning the corresponding mark to the front. To facilitate setting and to hold the type-wheel in the set position, there is provided a spring-pressed pin j, adapted to engage during the impression stroke with one of a series of longitudinal grooves k in the plunger. The pin normally engages a circumferential groove i in the plunger and the operator turns the knob until the pin snaps into the required groove and then depresses the knob. The knob is provided with a contact y<5> adapted to engage during the impression stroke with one of a series of contacts y' each of which is connected to one of a series of counters, the arrangement being such that the counter corresponding to the value of the ticket is operated. The counters are provided with a common return which is in electrical connexion with the contact y<5> through the plunger and the framework. The total number of tickets issued is indicated by a counter z<1> operated by the engagement of a rod on the cross-head with a lever z<2>. Roller inking-arrangements.-During the impression stroke, the printing-surfaces wipe over an inking-roller q which is carried by a spring- pressed lever r pivoted on the framework. Web guiding and cutting arrangements; paper-supports.-The strip or web t is led through a gnide t<3> and feed-rollers u, u<1> and over a rubber impression-bed v<1>. The ticket is partly severed from the strip by a pivoted knife v which is operated during the impression stroke by a stud v<4> on the cross-head e. During the return of the cross-head the strip is fed by the mechanism described below. The bed v1 is provided with a side-flange v<2> which holds the strip against lateral movement while the ticket or a series of tickets is being torn off. Line-spacing mechanism.-The feed-roller u is provided with a ratchet wheel w engaged by a' feed-pawl w<1> carried by a loose disk w<2> which is connected by a slotted link x to the cross-head e. The ratchet-wheel is also engaged by a detent w<3>, the feed and detent teeth of the ratchetwheel being arranged side by side and facing in opposite directions and the detent teeth being formed with notches w<4> to engage the detent. At the end of the down-stroke of the cross-head, a pin w<5> on the disk lifts the detent, and, during the upstroke of the cross-head by the springs h The feed-pawl rotates the feed-rollers. The slotted connexion x<3> permits the knife to return before the feed takes place. According to the Provisional Specification, the spacing- mechanism is connected to the plunger by a cord which is wrapped round a spring drum.
