ABSTRACT:
A clamp comprises a pair of pivotally connected jaws. A spring urges the jaws apart. A screw extends from the first jaw through the second jaw and projects above the second jaw. An operating lever for clamping and unclamping the jaws is screw threadedly received on the screw above the second jaw. The screw may be locked against rotation by engagement of the screw with a seat in the first jaw. With the screw locked against rotation, rotation of the lever around the screw selectively clamps and unclamps the jaws around an article. To adjust the distance of separation between the clamping surfaces of the jaws before rotation of the lever, the screw is axially shifted off its seat on the first jaw and the screw is then rotated with respect to the operating lever to adjust the height of the operating lever along the screw. Thereafter, the screw reengages the seat in the first jaw to prevent further rotation of the screw.
