Patent ID: 8549706

Claim:
A door hinge comprising: a knuckle defining a pivot axis; first and second leaves extending from the knuckle and pivotal relative to each other about the axis; a housing fixable in a door jamb or door edge and formed with first and second throughgoing slots spaced apart along the axis, elongated parallel to the axis, and open perpendicular to the axis and with respective third and fourth threaded holes spaced apart along the axis and throughgoing perpendicular to the axis; a holder in the housing and formed by a pair of bent sheet-metal brackets forming two end faces extending at an acute angle to the axis and respectively aligned with the third and fourth threaded holes; rivets securing together the brackets to form a cavity in which the first leaf is engaged; respective first and second screws extending through the slots transversely of the axis and seated in the holder, the first and second screws being tightenable to fix the holder against movement parallel to the axis in the housing and being loosenable to permit such movement; respective third and fourth screws seated in the third and fourth holes and engageable with the end faces, whereby tightening of one of the third and fourth screws against the respective end face and loosening of the other of the third and fourth screws away from the respective end face shifts the holder in the housing parallel to the axis; and a pair of rotatable and externally threaded spindles extending across the cavity and threaded to the first leaf such that rotation of the spindles adjusts a position of the first leaf in the cavity relative to the holder.
