ABSTRACT:
A light to moderate duty work-holding clamp which also can be used as a gear or wheel puller. The body of the clamp is formed of two C-shaped plates, aligned and spaced apart by 2 blocks, one attached to each end of the C-shape. A large clamping screw is threaded through each block. The blocks are mounted to the plates in a pivotable manner, so that the two clamping screws can be pivoted through 360 degrees freely. One end of each of these two clamping screws has a bearing face for bearing the pressure to be applied by the screws. These bearing faces can be snapped on and off the ends of the screws. The other end of each of these two screws terminates in a hook-shaped portion, which can provide the gear pulling function if used in combination with a third clamping screw. This third clamping screw is threaded through a third block which is attached slidably between the C-shaped plates. This block can slide to any point along the C-shape between the first two blocks, turning as it moves along. The third clamping screw thus also changes its angle as the block is slid. One end of the third screw again ends in a snap-removable bearing face, while at the other end is an enlarged knurled knob to aid in turning the screw. This third block has a set screw so that it can be secured anywhere along the C-shape. The first two blocks can be locked in either a horizontal position or a vertical position by means of pins inserted through holes in the plates and aligned holes in the blocks.
