  • Automatically closing adjustable clamp
    Patent number: 6971641
    Abstract: A clamp which can be closed with one hand consists of two telescoping sleeves, one inside the other, with a fixed jaw at one end of the inner sleeve and a movable jaw that is caused to travel back and forth along the length of the inner sleeve by means of a connecting band. This band is routed around two rotating spindles within the body of the clamp in such a way that when the fixed jaw is placed against the work and the outer sleeve is drawn back, the movable jaw moves forward until it contacts the other side of the work. The clamp is then tightened by means of a handle mounted on a threaded shaft.
