Abstract
An adjustable gripping and locking tool having a body (28) to which is attached an elongated handle (22) and a pivoting handle (26). An adjustable jaw (34) is slidably mounted on the body and an adjusting lever (52) cooperates with the adjustable jaw to adjust it toward and away from a fixed jaw (24). The adjusting lever is attached to the pivoting handle and is operated with the hand holding the tool, as is the locking and unlocking operation. The construction of the tool permits the adjustment of the jaws directly against the work piece and eliminates the tedious and time-consuming operation of turning a threaded screw back and forth several times to effect an adjustment that will permit the jaws to be locked on an object.
Claims15
An adjustable gripping and locking hand tool comprising:
- a body pivotably attached to an elongated handle, a pivoting handle attached to said body, both of said handles being U-shaped in cross section, a fixed jaw on said elongated handle, an adjustable jaw on said body, a fulcrum bar disposed between said elongated handle and said pivoting handle, means for mounting said adjustable jaw on said body, and means for adjusting said adjustable jaw toward and away from said fixed jaw.
The hand tool of claim I wherein a coil spring is contained within said elongated handle in axial alignment therewith, the outwardly facing end of said spring being disposed up against inwardly extending arms on said handle, the inwardly facing end of said spring being in contact with and held in position by one end of said fulcrum bar, and the other end of said fulcrum bar being attached to said pivoting handle by a pivot pin.
In an adjustable gripping and locking tool, the combination of:
- a body, an elongated handle and a pivoting handle attached pivotably to said body, both of said handles being of U-shaped cross section, a fixed jaw on said elongated handle, an adjustable jaw mounted on said body, a fulcrum bar disposed between said handles, means for attaching said adjustable jaw to said body, and means for moving said adjustable jaw toward and away from said fixed jaw.
In an adjustable gripping and locking tool having an elongated handle, a fixed jaw on said handle, an adjustable jaw attached to said elongated handle operated by a pivoting handle, a fulcrum bar, and an adjusting screw, wherein the improvement comprises;
- different means for mounting said adjustable jaw on said tool, and different means for adjusting said adjustable jaw, both of said means resulting in a tool whereby it can be operated more quickly and efficiently with just one hand.
