Pin belt mechanism for movement of a continuous strip

Mechanism for movement of a continuous strip provided with a longitudinal row of apertures comprising:

• a pair of parallel shafts, there being a first shaft and a second shaft, the strip being arranged to move at right angles to the shafts, the shafts being longer in length than the width of the strip,
• a carriage having an opening therethrough, the first shaft extending through the opening, the carriage being movable along the first shaft,
• a drive wheel, the second shaft extending through the drive wheel for rotation of the drive wheel with rotation of the second shaft, the drive wheel being movable along the second shaft,
• a second wheel rotatably carried by the carriage and spaced from both of the shafts,
• a continuous belt encompassing the drive wheel and the second wheel for rotation therewith,
• a plurality of pin members carried by the belt, each of the pin members extending through the belt and being movable with rotation of the belt,
• the carriage being provided with a recess having an internal wall provided with an elongate aperture therein, the mechanism including an internally threaded stem having a part within the recess and engaging the apertured wall, a stud extending through the aperture of the wall and into the internally threaded stem for clamping the stem with respect to the internal wall and thus retaining the stem with respect to the carriage, a part of the stem extending from the recess, the second wheel being rotatable upon said part of the stem which extends from the recess, the stem and the stud being laterally adjustably movable within the aperture of the internal wall to adjust the spacing between the second wheel and the drive wheel.

• a plurality of pin members carried by the belt, each of the pin members extending through the belt and being movable with rotation of the belt,
• the pin members of the belt being movable into the apertures of the continuous strip,
• the carriage having a second opening adjacent the first said opening, the openings being connected by a slot therebetween, means extending into the carriage through the slot and engageable with a portion of the carriage which is adjacent the slot, said means being adjustable to slightly move said portion of the carriage to change the dimension of the slot and to change the dimension of the openings, to provide a clamping pressure upon the shaft which extends through the first said opening.
