Abstract: The invention is a patch for a pivot hinge having an attachment lug, the lug being a substantially rectangular prism having a plate face and a cover plate attached to the attachment lug at the plate face, the cover plate being a substantially flat rectangular prism. The lug has two through holes that penetrate two opposing faces of the lug, other than the plate face, the holes being chamfered at one end and threaded along the remaining, non-chamfered portion. The plate is substantially larger than the plate face of the lug, and the lug and the plate consist of a single piece of unitary construction, and the thickness of the plate perpendicular to the plate face of the lug is 1/16th of an inch.
