Patent number: 5435030Abstract: A combination hinge adjustment and pintle removal tool which has the ability to perform three functions in a single wrench-shaped hand tool. A first end of the tool includes a punch tip mounted orthogonal to the longitudinal axis of the tool, which is used to initially dislodge the hinge pintle from the hinge by driving the opposite side of the tool body with a hammer. The same end of the tool also includes a cupped indentation centered colinear with the longitudinal axis of the tool. The radius of this indentation is such that it will snugly fit around the shaft of a hinge pintle beneath the head of the pintle so that it may be hammer-driven upward in order to complete removal from the hinge. The second, or opposite end of the tool includes an opening with an offset spanner tip on one of the jaws surrounding the aperture. This end of the tool is used to bend a hinge without a pintle into alignment when adjusting the door within a jam or frame.Type: GrantFiled: September 23, 1993Date of Patent: July 25, 1995Inventor: Michael A.
