A conventional butt hinge including a pair of first and second relatively swingable superposed hinge leaves is provided and the leaves include registered sets of apertures formed therethrough with the adjacent ends of registered apertures being countersunk. A thick backing plate overlies the side of the first leaf remote from the second leaf and is provided with threaded bores aligned with the registered apertures formed in the leaves. Threaded studs are threadedly engaged in the threaded bores with one set of corresponding ends of the studs flush with the side of the backing plate remote from the hinge and the other set of ends of the threaded studs are sharpened and project outwardly from the ends of the apertures opening outwardly of the side of the second leaf remote from the first leaf. Threaded nuts having rounded opposite ends are threaded onto the studs between the hinge leaves and are received in the countersunk ends of the registered apertures. In use, the second hinge leaf is seated in a door edge mortise and the first hinge leaf is swung into position thereover with the pointed ends of the studs projecting through the apertures of the first leaf and engaged against the door edge in the bottom of the mortise. Then, a hammer or other impact implement is utilized to strike the backing plate to drive the pointed ends of the studs into the door edge forming depressions therein to determine the location of the attaching screw holes to be formed in the door edge. |
