Abstract
Abstract This invention relates to an effective means of removing the hinge pin, particularly of a plate type hinge, when it is necessary to remove the hinge pin in order that the door may be removed from its mounting. My hinge pin removing tool provides a sturdy driver type device which can be struck with a hammer in order to drive the hinge pin out of its socket, particularly when the hinge pin is rusted or has been painted while in place.
