Abstract: 500,923. Printing-machines ; cutting webs. DENNISON-VICTOR CO., Ltd. April 13, 1938, No. 11370. Convention date, April 13, 1937. [Class 100 (i)] [Also in Group VIII] In a ticket-printing machine of the kind in which a ticket strip is fed between a type assembly and a platen carried by a fixed frame and a movable head, the strip is fed by a reciprocating feedfinger engaging feed openings in the strip and the printed ticket is severed by a knife shaped to bridge the finger and adapted to sever narrow ticket connecting necks on each side of the feed opening. The movable head 37, Fig. 4, which is rocked on a pivot 40 on the fixed frame by connections from a cam on the main driving shaft comprises a side wall 42, a front wall 118 carrying the platen 85 and a rear inclined wall 41 carrying adjustable side guides 22 for the ticket strip. An arm 21 supported from the wall 42 is arranged so that its edge engages the upper surface of the strip. A plate 44 secured to the bottom of the head 37 is channeled to form a guide for a slide bar 71, the front end of which is recessed to receive a feed finger 72 having a feed prong 73 pressed upwardly through an opening in a plate 76 covering the recess by means of a spring 79. The slide 71 is actuated by a link 70 from the mechanism actuating the head 37. A plate 81 carried by a member 80 adjustable along a slot 42a in the wall 42 serves, during the feed movement of the slide to hold the prong 73 depressed until it reaches the front edge of the plate, this adjustment permitting of feeding tickets of different length. The feed openings 2, Fig. 9, in the strip are in the form of slots and the strip is provided with slits 4 in line with the slots leaving short connecting necks 5. The edge of the cutter 100, Figs. 3 and 4, is recessed to bridge the prong 73. The feed of the strip takes place on the upward movement of the head 37, bringing a previously printed ticket beyond the platen 85 and the prong 73 in line with the cutter. Further upward movement of the platen causes a downward movement of the cutter severing. the necks 5 against the plate 76. This movement of the cutter is effected by the following mechanism. The cutter 100 is secured to an angle member 120 pivoted to lugs 114 on a rocker 111 pivoted at 112 to the head 37 and carrying a swivel block 107 through which ban slide a sleeve 104 mounted on a rod 102 pivoted to the machine frame at 106. A spring 105 adjustable by nuts 108, 109 engages a flange 104a on the sleeve 104 to press the end of the sleeve against stop nuts 103 on the rod 102. On the upward movement of the head 37, the block 107 moves freely on the sleeve 104 until it engages the flange 104a when the rocker 111 is turned to move the cutter downwardly to sever the strip. Adjustment of the cutter into line with the slots 2 is effected by a setscrew 117 bearing against the wall 118 of the head 37 and the set-screw is pressed against this wall by a spring 123. The link 70 actuating the slide 71 is connected to a block 78, which at the end of the feed stroke of the slide engages a stop 140, a resilient connection being provided in the means for actuating the link 70. The block 78 is adjustably connected to the slide by a screw and nut 83, 82 so that the position of the prong 73 at the end of the feed stroke and thus the position of the printed matter on the ticket may be varied. The nuts 108, 109 may be so slackened that the cutter creases the necks 5 instead of completely severing them, or by further slackening the nuts the cutter may be rendered normally inoperative but may be actuated as desired by manual pressure upon the rocker 111. The machine may operate on ticket strips such as that shown in Fig. 10 in which each ticket separated by feed slots 2 and connecting necks 5 has one or more detachable parts. To enable the feeding of such a strip without severing the detachable parts, they are provided with feed slots 5a of a width enabling the free passage therethrough of the cutter blade.
