ABSTRACT:
An adjustable leverage claw hammer for providing increased leverage when removing nails of various lengths. The claw hammer includes a standard hammer head mounted on one end of a handle. The hammer head has a first end with a striking surface for engaging nails and a second end forming a pair of claws used for removing nails. The hammer head has a "U" shaped cap assembly rotatably pinned thereon. The cap assembly has a convex shaped top portion disposed above the top of the hammer head which acts as a fulcrum for engaging a working surface having a nail driven therein. Extending downwardly from the top portion of the cap assembly is a pair of side plates having a plurality of detent teeth disposed along an interior surface of the side plates. The detent teeth are positioned adjacent opposite sides of the hammer head. A slot is cut through a portion of the second end of the hammer head and adjacent the claws. The slot is used to receive a spring biased lock assembly. A portion of the lock assembly is received inside grooves between the detent teeth of the cap assembly. By adjusting the lock bar in a selected groove between the detent teeth, the cap assembly can be raised and lowered above the hammer head for adjusting leverage of the claw hammer when removing nails of various lengths from the working surface.
