Abstract: 405,123. Ticket-printing machines. DENNISON MANUFACTURING CO., Ltd., Minerva Road, Park Royal, London.-(Dennison Manufacturing Co. ; Howard Street, Framingham, Massachusetts, U.S.A.) Oct. 7, 1932, No. 5659/33. Divided application. [Classes 100 (i) and 100 (ii).] Platen machines; feeding webs; cutting- apparatus.-A ticket printing and feeding apparatus comprises mechanism for feeding the tickets and delivering them successively from the apparatus, a device for printing on the tickets, and mechanism for actuating the printing- device to produce either one or more than one impression of the same matter on each ticket, such mechanism operating during one or more predetermined pauses in the feed movement of the ticket. Preferably the feed mechanism is arranged to advance each ticket in two stages the length of the first of which is adjustable to enable either short or long tickets to be supplied, and a cutter may be operated during a pause in the two stages of the feed to sever each ticket from the strip. A guideway for the tickets is mounted on a table 17 and comprises baseplates provided with strips 42, 43 and 42<1>, 43<1>. Pawl or feed fingers 51, 53 normally pressed downwardly by coil springs towards the guideway are connected through stub shafts to crank levers 47, 46 respectively which project through a slot 44 formed in the table 17. The levers 46, 47 are pivoted on stub shafts and carry on their lower arms rollers held by means of springs in engagement with cams 32, 33 respectively which are mounted on a shaft 26 driven through worm reduction gearing 29, 30 from a motor. A cutter 63 attached to the upper arm of a bell-crank lever 67 pivoted on a shaft 68 is mounted to extend across the ticket guideway and co-operates with hardened insert strips adjacent a slot in the table 17 provided for the passage of the cutter. The end of the pawl 53 is specially shaped so that it cannot engage the slot in the table 17. The lower arm of the lever 67 is spring-pressed towards, and carries a roller 70 for engagement with, a cam 36 on the shaft 26, movement of the lever to raise the cutter 63 being limited by the provision of a stop 71 which engages the end of a slot in the table 17 through which the lever passes. A printing-head 92 is carried by a lever 74 pinned on the shaft 68, and two arms 75, 76 are also mounted on the shaft, the former arm being pinned to the shaft and secured by a bolt to the latter arm. The arm 76 is provided with a boss 77 in which a pin 78 carrying a roller 79 is slidable by means of a hand-lever 81 adapted to engage a screw secured to the slidable pin. The bolt connecting the arms passes through a relatively large hole in the arm 75 and a setscrew 75c projecting into the hole adjusts the relative positions of the two arms to a small extent to enable the printing-head to be adjusted. The lever 81 can be operated to engage the roller 79 with a cam 34, or with both the cams 34, 36; a spring 84 on the arm 75 is adapted to retain the arm 76 against the cams. The feed pawl 51 is reciprocated through a stroke which is sufficient to enable relatively long tickets 80 to be fed, a part of this stroke being rendered ineffective when short tickets are required by means of a flat plate 86 which extends longitudinally of the guideway and bears downwardly upon the ticket strip to tension and restrain it, and is adjustable longitudinally so that the pawl 51 rides over it during part of its stroke when short tickets are to be produced. The plate 86 carries at its rear end a threaded pin 87 which passes through, and is secured by a nut 91 in, a longitudinal slot 88 provided in a guide-strip 89 secured to the guide-strips 42, 43. The rear end of the strip 89 curves upwardly for guiding a continuous strip of tickets from a magazine 102 to the guideway in the table 17. The feed pawl 51 is adapted to engage the rear end portion of a ticket in the strip and to move preferably up to the cutter 63 to advance the end of the ticket past the latter to the correct cutting-position. The feed pawl 53 is adapted to push each ticket, after it has been severed, out of theguideway, but its advance is arrested, by the cam 32, beneath the printing-head 92 to allow printing. Spring fingers 93, 94 hold the ticket against movement on the retraction of the pawl 51. When only one impression is to be made on either a long or a short ticket the roller 79 only engages the cam 34, but where long tickets are used and it is desired to print data in duplicate at the front and rear ends of such tickets the roller 79 engages both the cams 34, 36. In this case the impression is made on the leading end of a ticket while the latter is in the cutting-position shown in Fig. 4, and just before the cutter is actuated ; immediately after the first impression the cutter is operated, and then the pawl 53 pushes the ticket as before, causing the rear end to pause beneath the printing-head for a repeat impression, and then to advance it to the delivery position. If desired the pawl 51 may be operated in two-part strokes, and the pawl 53 in uninterrupted strokes ; in this case the strip is advanced by the pawls 51, printed during a pause, advanced to severing position where it is again printed, and is then delivered by the pawl 53. The tickets in the continuous strip may be separated from each other by apertures or notches and these may be engaged by the feed pawl 51. The type carried by the head 92 is inked before each printing operation by means comprising an inking-pad 96 secured to an arm 98 mounted on a fixed shaft or pivot 99. The head 92 is pivotally connected to the arm 98 by a link 101 such that the pad 96 is forced against the type at the upper limit of the arm 74.
