Abstract: 480,736. Ticket-printing machines., DENNISON-VICTOR CO., Ltd. April 17, 1937, No. 10996. Convention date, May 29, 1936. [Classes 100 (i), 100 (ii), and 100 (iv)] Platen machines; feeding webs ; cutting- apparatus ; type-setting arrangements.-In apparatus for printing and supplying tickets of the kind comprising means for feeding strip ticket stock towards a printing-station, a cutter which cuts off successive tickets, and guides which engage opposite edges of the tickets and stock so as to guide these towards the printing-station, the guides are relatively adjustable to suit the width of the stock and tickets. The printing-mechanism comprises a primary set of printing-wheels with a corresponding set of indicating-elements, and a secondary set of printing-wheels with a corresponding set of indicating-elements, both sets of wheels being selectively adjustable to print indications on each ticket along lines at right-angles and in spaced relation to each other. The machine is operated from a single main shaft 18 driven through reduction gearing by a motor 10, a lever 23 being provided to operate a one-revolution clutch whereby the shaft is adapted to be driven one revolution. The ticket strip 30 passes from a drum 31 into a guide track provided by two spaced grooved guides 35 each mounted for transverse adjustment on a table 5. These guides are offset to pass around the platen 100, and are adjusted to suit different widths of ticket strip. The ticket strip is perforated for engagement by a single spring-pressed feeding- finger 73, Fig. 7, and the cut-off ticket is fed by the frictional engagment of a pair of spring- pressed fingers 61. The fingers 61 are slidably arranged on a bar 60 supported in a pair of arms 57 reciprocated by a cam 50, and the fingers are engaged by and adjusted with the guides 35 for the ticket strip. A link 68 on one arm 57 has a slot 69 engaging a pin one one of a pair of control arms 71, the latter carrying a cross shaft on which the finger 73 is mounted. The arms 71 are urged by spring-pressure to move with the arms 57, but an adjustable stop 80 having two abutments 83, 84 limits the movement of the arms 71, and hence the feed of the strip 30, according to whether a short or a long ticket is desired. The end of the ticket strip is guided by a pair of plates 89, 90 on the guides 35, the forward ends of these plates co-operating with a shear-blade 95 which severs the ticket from the strip prior to printing. The blade 95 is secured to a pivoted bell-crank lever operated from a face-cam 96. The printing and inking apparatus are controlled from either of a pair of cams 120, 120a, according to whether they are to be operated twice or once in a cycle of the machine, by the setting of a two-armed pivoted lever 113 in notches in a latch 114 pivoted on a shaft 81. The latch 114 is connected to the stop device 80 so that on moving the control lever 113 the feed of the ticket strip is varied. If a long ticket is desired, it is printed twice, in which case, during one cycle of the machine the platen 100 and the inking apparatus are operated twice. The cams 120, 120a operate through a system of levers to bring an ink pad on the end of a pair of arms 133 into and out of contact with the printing-wheels 162 of the secondary printing-device A and those of the main printing-device P, and then to raise the platen 100 to press the ticket into contact with the wheels. A sheet metal member holds the ticket in position on the platen during printing. The main printing- device P for printing a staggered line of symbols transversely of the ticket is of known type and, comprises sets of printing indicating wheels operated by a setting-knob 150. Disposed adjacent to one end of the device P is the secondary printing-device A for printing a single line of price indications transversely of the staggered line of symbols. Both printing-devices are in one unit mounted to pivot on the shaft 81, and can be raised to the inoperative position by an arm 205 secured to an eccentric. When the unit is inoperative, an arm 200 movable therewith moves into the path of one of the arms 71 of the ticket strip feeding means, in which case only the feeding- fingers 61 reciprocate to feed the fast ticket from the printing-station to a position where it is pinned to an article such as a garment. The printing-device A, Fig. 15, comprises indicating-wheels 163 and printing-wheels 162 provided with a series of slots mounted on a longitudinally movable and rotatable shaft 164. Collars 165, 166 have pins which can engage the slots in a pair of indicating and printing wheels whereby on rotating the shaft 164 the wheels are set. The shaft 164 is arranged within a rack-bar 167 with keys to hold all the wheels except those being set by the collars, and by means of a pair of pawl levers the rack-bar can be moved step by step to hold each wheel when it is set by the collars. Specification 405,123 is referred to.
