  • the lever 36 is urged in a clockwise direction (FIG. 7) by means of a spring 39 wrapped around the pivot 37 with its ends hooked over pins 41 and 42 on the levers 31 and 36 respectively.
  • a screw 43 bears on pin 41 to limit the extend to which the spring 39 can swing the lever 36 clockwise, thereby to control the stroke of the feed pawl 33. Should the ticket strip S jam, the lever 36 stops while lever 31 continues to swing clockwise, the pin 41 leaving the adjusting screw 43 and the spring 39 being further tensioned.
  • a cutter comprising a stationary blade 44 and a blade 46 mounted on a crank arm 47 actuated by an arm 48, links 49 and 51, lever 52, and cam 53.
  • the type at the printing position (line 1212 in FIG. 11) is inked by rollers 56 which oscillate back and forth from the retracted position shown in FIGS. 4 and 10, over ink pad 57, through the inking position shown in FIG. 11 to the advanced position shown in full lines in FIG. 7 and in broken lines in FIG. 11.
  • the inking pad may be constructed as described and claimed in the copending application of Wallace 1. Satas, Ser. No. 437,515, filed on even date herewith.
  • the ink rollers are actuated by the aforesaid cam 28, cam follower 58, lever 59, link 61, rack 62, pinion 63, circular rack 64 sliding in a guide 66, links 67 and roller supports 68.
  • cam followers 29 and 58 ride in the same endless cam groove 28.
  • Lever 59 rocks back and forth between the positions shown in FIGS. 4 and 7 and lever 31 rocks back and forth correspondingly, the levers always being parallel to each other as shown in FIG. 7.
  • a spring 69 urges the ink rollers clockwise (FIG. 11) about the shaft 71 yieldingly to press the rollers against the ink pad, type and guides 81.
  • guides 72 are disposed on opposite sides of the dial-set wheels in alignment with the row of type in printing position (FIGS. 2, and 11). Slidable in these guides are printing plates 75 carrying additional type such as K BRAND in FIG. 2. At one location around each wheel is a blank space carrying no type so that a printing plate may he slipped in from the guides 72 with its type in the same plane as the wheel type in the printing row. Preferably the blank spaces have flat surfaces abutting the back of the printing plate.
  • Auxiliary guides 73 may be provided adjacent to the main guide 72 and in the same plane to receive auxiliary printing plates 74.
  • the apparatus prints a ticket T such as shown in FIG. 3, the wheels printing 00000, the main plate printing K BRAND and the auxiliary plate printing REGULAR WRAP.
  • each inking roller has rollers 77 and 78 on its trunnions.
  • Rollers 77 are keyed to the trunnions at 79 and rollers 78 have anti-friction bearings freely rotatable on the trunnions.
  • guides 81 Extending past the inking position (line 1212 of FIG. 11) on opposite sides of the printing wheels are guides 81 which are pivotally mounted on shaft '82 and yieldingly urged in a counterclockwise direction (FIG. 10) by springs 83 yieldingly to hold the guides in the position shown in FIGS. 2 and 10.
  • a lever 84 is pivoted at'SS to retract the guides 81 from operative position to the retracted position shown in broken lines, thereby to permit the insertion of printing plates such as shown at 74 and 75 in FIG. 2.
  • the guides 81 are disposed in a plane approximately tangential to their printing wheels at the printing station.
  • Each guide has two tracks for the rollers 77 and 78 respcctively (FIGS. 12, 13 and 14) and each track has high and low portions.
  • the track for each of the rollers 77 has a high portion 86 extending past the printing row of type where the type is inked and a low portion 87 beyond the inking region, and the track for each of the rollers 78 has a low portion 88 adjacent the high portion 86 and a high portion 89 adjacent the low portion 87, the two high portionsbeing in the same plane and the two low portions being in the same plane.
  • the inking rollers roll over the type they are supported by rolls 77 on the high portions 86 as shown in FIG.
  • the rolls 77 preferably being formed of fiber to increase the friction between rolls and tracks.
  • the high portions 86 of the track and the means for moving the ink roller along the track constitute means for driving the ink roller at the speed at which it rolls over the type.
  • each roll 77 leaves the high portion 86 and each roll '78 engages the high portion 89, which constitutes idling means to permit the inking rollers to turn freely by inertia (FIG. 14).
