Abstract: A non-mortised door hinge is formed of a large and a small hinge leaf pivotally interconnected about a pivot pin, the smaller leaf being of substantially the same size and shape as a central cut-out in the larger leaf for nesting within the cut-out area of the larger leaf to form a hinge of single leaf thickness. At least one of the upper and lower peripheral edges of the smaller leaf taper away from the corresponding upper and lower margins of the cut out area for increasing the clearance therebetween with increasing distance from the pivot pin. The hinge has horizontally slotted screw holes on one leaf and vertically slotted screw holes on the other leaf. The slotted holes are used to attach the hinge to a door and frame using screws, while permitting subsequent alignment of the door in its frame. At least one round (non-slotted) hole is also provided on each leaf to accept a setting screw.
