Abstract
A multi-range auto-advance bar clamp used for clamping work pieces together which may upon release of the brake instantly and automatically adjust from a wide open position to any desired closed position. The multi-range auto-advance bar clamp may comprise a slide bar, a movable jaw, a sliding jaw, a body, a drive assembly and a brake, an advancement mechanism, a rigid structural body extension and a slide rail. The jaws of the clamp are adjustably separated and positioned about a work piece. A mechanism for controlling the speed with which the clamp automatically closes may also be provided.
Claims25
A bar clamp comprising:
- a body;
- a slide bar slidably mounted to the body said slide bar having a first length;
- a first jaw mounted on the slide bar;
- and
- a second jaw mounted on the body in opposed relationship to the first jaw;
- said slide bar being movable between a first position where the first jaw is in a closed position and a second position where the first jaw is in a maximum open position, the distance between the first position and the second position being greater than the first length.

A bar clamp comprising:
- a body;
- a slide bar slidably mounted to the body;
- a first jaw mounted on the slide bar;
- a second jaw mounted on the body in opposed relationship to the first jaw, said second jaw being repositionable relative to the body;
- a drive mechanism for moving the slide bar in a first direction;
- a brake movable between an engaged position and a disengaged position where when the brake is in the engaged position the slide bar is prevented from moving in a second direction opposite to the first direction;
