Definitions

  • I provide translating mechanism of the kind referred to in which the ends of a plurality of belts passing over pulleys are attached to members, each released for movement through a given distance by power driven means in accordance with the elements to be translated in such a manner that the movement of a character selecting mechanism is the aggregation of the movement given to all the belts.
  • Fig. 2 is a plan view mechanism showing how and Fig. 3 shows one manner in which the translating mechanism may be actuated.
  • a belt 5 in the form of a steel tape which passes over a pulley 6.
  • the other end of the steel tape is attached to a pin 1.
  • a grooved wheel On the same spindle as the pulley 6 is a grooved wheel it which slides in a slot in a fixed frame I2.
  • the spindle of the grooved wheel ill and pulley t is fixed to a frame 8 to which is also fixed a second grooved wheel I i also sliding in the slot in the frame H2.
  • the frame 8 is under the action of the belt 5 and a spring I3 is fixed at one end to the sliding frame 8 and at the other to the fixed frame I2.
  • a rack 9 is fixed to the frame 8 and meshes with a gear wheel M on the spindle of which is fixed a type wheel Hi.
  • crank pin 4 rotates through half a revolution and the pulley 6 and frame 8 move through half the throw of the pin 4. This movement is communicated to the type wheel I5, the gearing being such that the type wheel also makes half a revolution.
  • the belts 5' and 5" attached to crank pins 4' and 3" respectively pass over pulleys 6' and 6" and are attached to pins 1' and 1" respectively.
  • the pin l to which belt 5 is attached is mounted on the frame 8 carrying the pulley 6'.
  • the pin 7' to which the belt 5' is attached is mounted on the frame 8" carrying the pulley 6".
  • pins 7, 1', etc. By placing the pins 7, 1', etc. on moveable frames carrying the pulleys, these pins may be placed at such a distance to the left in Fig. 2 that a very compact structure results and the whole mechanism is contained within workable limits.
  • a combination bar and forked detent has been shown in Fig. 1, other means of releasing the disc 3 for half a revolution may be used.
  • One such means is illustrated in Fig. 3 which also shows another means of driving the disc
  • the disc 3 is provided With a hub 3 which fits Within a hollow bearing I? carried on a fixed frame. On the bearing I7 is loosely carried a toothed wheel i8 attached to a gear wheel i3 continuously driven. A pawl 2
  • is held out of engagement with the wheel it by means of a two armed detent lever and when the pin 4 is at the opposite end of its diameter by a similar detent lever 24.
  • the two levers 23 and 24 are pivoted on pins 25 and 23 and held in engagement with pawl 2
  • the disc 3 is held in either of its two positions by a detent lever 28 pivoted on pin 25 and held in notch 30 or notch 3
  • the levers 23 and 24 may be selectively depressed according to the nature of the element of a character by moving an intermediate piece to left or right above the ends of their horizontal portions and striking this piece down for each character.
  • the intermediate piece may be struck downwards by a cam after all such pieces have been set by the elements of a received signal.
  • Translating mechanism comprising in combination a series of members, power driven means tending to move each of said members, detent means for releasing each of said members for a predetermined movement only, a belt, a pulley, and a frame carrying said pulley for each member, the belt passing over the pulley and having one end attached to the member and the other end attached to the frame, the other end of the last belt being attached to a fixed point, grooved wheels fixed to each frame and adapted to move in a slot in a fixed frame, an indicating member adapted for movement by one pulley, means for keeping each belt under tension, and means for operating said detent means in a combination representing a character to be translated.
  • Translating mechanism comprising in combination a series of discs tending to be continuously driven by common power driven means, detent means individual to each disc for holding said disc from rotation and when actuated allowing a rotation of half a revolution only, a crank pin on each disc, a metallic tape, a pulley and a frame carrying said pulley for each crank pin,
