Definitions

  • a printing and reinking mechanism which includes a member supporting a printing element and adapted for movement in a printing direction, means for selectively controlling the movement of the support member in a printing direction, a reinking member adapted for movement to a position engaging the printing element and actuating means for moving said printing element and the reinking member to provide a reinking operation and'a printing operation.
  • a printing and reinking mechanism which includes a reinking member slidably mounted. for movement perpendicular to the movement of a printing member, drive means for moving the reinking member and the printing member in a direction to provide either a printing operation or a reinking operation and control means for selectively controlling the movement of the printing member to select either a printing operation or a reinking operation.
  • FIG. 1 is a partial detailed side view showing the printing'mechanism and the reinking mechanism.
  • FIG. 2 is a sectional front view of the cam line and the cam follower arms which are utilized to control the operation of both the printing mechanism and the reinking mechanism.
  • FIG. 1 there is shown a side view of the reinking mechanism and the printing mechanism.
  • a slip table 21 Secured to the side frame of the data input device is a slip table 21 having a guide member 22 positioned adjacent therewith.
  • a support member 24 Slidably supported by clips 23 mounted on the slip table 21 is a support member 24 to which is attached a reinking pad 25 at one of its ends.
  • the other end of the support member has mounted thereon a lug 26 to which is rotatably mounted one end of an arm member 27 rotatably supported on a stud 28 secured to the side frame 20.
  • the other end of the arm 27 is rotatably connected to one end of a link member 30, the other end of which is rotatably secured to one end of a lever member 31, which in turn is rotatably mounted on a stud 32 secured to the side frame 20.
  • a spring 33 mounted between the arm 27 and a stud 34 located on the side frame 20 normally urges the arm 27 in a counter-clockwise direction about the stud 28. This movement is transmitted to the lever member 31 by the link 30.
  • a cam follower arm 36 (FIG. 2) rotatably mounted on a shaft 37 located within the framework of the machine.
  • the arm 36 is actuated by a cam member 38 secured to a cam shaft 40 in a manner well known in the art.
  • the cam member 38 will rock the arm 36 counter-clockwise and then clockwise about the shaft 37.
  • the counter-clockwise rotation of the arm 36 will rock the lever member 31 clockwise about the stud 32 which results in the rocking of the arm 27 in a clockwise direction. This clockwise movement will allow the arm 27 to move the support member 24 and the reinking pad 25 to the right as viewed in FIG. 1 against the action of the spring 33.
  • a printing member 41 mounted on a plate 42 slidably mounted on a pair of studs 43 secured to the side frame 20.
  • the studs 43 are positioned in a pair of cam slots 44 located in the plate 42.
  • Secured to the lower end of the plate 42 is a link 49.
  • a spring 45 mounted between the stud 46 located on the side frame 20 and a finger portion 47 of the link 49 normally urges the plate 42 in an upward direction as viewed in FIG. 1.
  • the upward movement of the plate 42 and the printing member 41 is controlled by acam follower arm 48 (FIGS. 1 and 2), one end of which is positioned within a slot 50 located in the link 49.
  • the cam follower arm 48 is rotatably mounted on a shaft 37 and is actuated by a cam member similar to cam 38 (FIG. 2) secured to the cam shaft 40.
  • the cyclic movement of the cam follower arm 48 will allow the plate 42 to move in an upward direction under the action of the spring 45 and then provide a return movement to its home position against the action of the spring 45. Due to the configuration of the slot 44, the movement of the plate 42 will follow a slight S pattern to allow the arm to clear inter fering structure located adjacent to the plate.
  • a latch member 51 (FIG. 1) rotatably mountedon a stud 52 secured to the side frame 20.
  • the latch member has a lip portion 53 which is normally urged into engagement with the plate 42 by a spring 54 mounted between the latch member and a stud 55.
  • the latch member 51 is engaged by an arm member 56 which is mounted on the armature 57 of a solenoid 58- mounted on the side 1 frame 20. Energizing of the solenoid 58 will result in the arm member 56 rocking the latch 1 member 51 counter-clockwise against the action of the spring 54. This movement will withdraw the lip portion 53 of the latch member from engagement with the plate 42 thus releasing the plate for movement in a upward direction.
  • the cam member operating the cam follower arm 48 will rock the arm 48 counter-clockwise (FIG. 2) twice during each revolution of the cam shaft 40. If the solenoid 58 has been energized prior to the operation of the cam shaft 40, thus removing the latch member 51 from the plate 42, the first counter-clockwise movement of the cam follower arm 48 will allow the spring 45 to move the plate 42in an upward direction to allow the printing member 41 toengage the reinking pad 25, thus reinking the printing member. The arm 48 will then be rocked clockwise by the cam member which action withdraws the printing member from the pad. At this time, the cam member 38 (FIG. 2) will rock the cam follower arm 36 counter-clockwise resulting in the movement of the support member 24 to the right as viewed in FIG, 1 against the action of the spring 33, thus removing the reinking pad 25 from the path of the printing member.
  • the cam follower arm 48 will again be rocked counter-clockwise to allow the spring 45 to move the plate 42 and printing member 41 in an upward direction thereby allowing the printing member to print on a record material located on the slip table 21.
  • the cam follower arm 48 will be rocked clockwise to move the printing member 41 .to its home position while the cam follower arm 36 is rocked clockwise to allow the spring 33 to move the reinking pad 25 to its home position as shown in FIG. 1.
  • the reinking mechanism is now in position for a subsequent reinking operation.
  • the solenoid 58 When the printing member 41 is to be operated in a printing operation without the reinking to occur, the solenoid 58 will not be energized during the first portion of the operation of thecam shaft, thus preventing the plate 42 from moving a distance sufficient to allow the printing member to engage the reinking pad 25. During the second portion of the cam shaft operation and after the reinking pad 25 has moved out of the path of the printing member, the solenoid 58 will be energized to allow the printing operation to occur. If during the operation of the machine no printing is to occur, the solenoid will not be energized during the operation of the cam line.

  • reinking means mounted for movement to a position blocking the movement of the printing means in said printing direction to reink said printing means upon movement of said printing means in a printing direction;
