ABSTRACT:
A butt hinge is comprised of first and second swingably coupled hinge plates. At least one of the hinge plates is provided with clearance openings to enable the said one hinge plate to be moved over a given range relative to portions of wood screws passing through said clearance openings. A trim plate overlies the said one hinge plate. The wood screws are tightened, sandwiching the said one hinge plate between a base of a mortise and the trim plate to maintain the hinge plate in proper alignment. Engaging surfaces of the hinge plate and trim plate may be roughened to enhance the clamping therebetween. The hinge plate may be provided with set screws threadedly engaging tapped openings in the hinge plate so as to project from the hinge plate surface to compensate for applications in which a depth of a mortise is greater than the combined thickness of the hinge plate and trim plate to bring the exposed surface of the trim plate flush with the surface in which the mortise is formed. Alternatively, one or more shims may be utilized as a substitute for the set screws.
