ABSTRACT:
There is disclosed a clamp which is particularly adapted for use in high-temperature applications in which arms bearing clamping faces are mounted on a flat bar in a manner such that they can be released to slide along the bar and clamped in any desired position. One arm has a fixed clamping face and the other arm has a movable clamping face movable toward the other. The latter is affixed to the free end of an elongate member adapted to reciprocate back and forth in the other arm and to be moved toward the first clamping face by a spiral cam. Means is provided for locking the arms to the backbone member and for locking the spiral cam in the clamping position.
