ABSTRACT:
A modification of conventional removable pin butt hinges, such as used to hang doors, simplifies removal of the hinge pin. The modification is a beveled surface portion along an upper end edge of the uppermost hinge cylinder, providing access to an exposed ledge portion of the hinge pin crown. A driver, a chisel, a screwdriver or other driving device may be positioned against the exposed portion of the hinge pin and struck, thereby easily driving the hinge pin from the hinge cylinder.
