Abstract: A door hinge has a knuckle defining a pivot axis, a pair of 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 a holder in the housing and formed by a pair of bent sheet-metal brackets. Rivets secure together the brackets to form a cavity in which one of the leaves is engaged. A pair of rotatable and externally threaded spindles extend across the cavity and are threaded to the one leaf such that rotation of the spindles adjusts a position of the one leaf in the cavity relative to the holder.

Abstract: A door hinge has a knuckle defining a pivot axis, a pair of 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 a holder in the housing. The holder is formed by a pair of bent sheet-metal brackets together forming a cavity in which engages one of the hinge leaves. One of the brackets has a face forming an acute angle to the axis. A pair of rotatable and externally threaded spindles extending across the cavity are threaded to the one leaf such that rotation of the spindles adjusts a position of the one leaf in the cavity relative to the holder. An adjustment screw threaded in the housing bears on the angled face so that the screw can be rotated to press against the face and cam the holder axially.

Abstract: A hinge for mounting a door-panel or window sash to a fixed jamb element has two leaves pivoted together about an axis. One of the leaves is adapted for attachment directly to an edge of one of the elements. A housing is recessed in the other of the elements and has a pair of generally parallel and vertical side walls with inner faces defining a horizontally open cavity. A bar is shiftable in the cavity horizontally perpendicular to the side walls and vertically. At least one fastener releasably securing the other of the leaves to the bar. A pair of spindles extending perpendicular to the side walls in the cavity are threaded into the bar and have opposite ends bearing on the inner faces of the side walls so that rotation of the spindles shifts the bar perpendicular to the side walls.

Abstract: A concealed door hinge has first and second leaf assemblies fittable into respective mortises in an edge of the door and in the door frame. The first leaf assembly has a body, mounting tabs at ends of the body and securable to the door frame or to an edge of the door, and an insert shiftable in the body in a first horizontal direction perpendicular to a face of the assembly. The body is also shiftable relative to the tabs in a second horizontal direction transverse to the horizontal direction and parallel to the face. A swivel mechanism is connected between the second leaf assembly and the insert of the assembly. Adjusters engaged between the insert, the body, and the tabs can relatively secure the insert and body in any of a plurality of positions offset relative to one another in the horizontal directions.

Abstract: A method of making a hinge has the steps of forming a region of a piece of sheet metal with a groove and then bending the piece of sheet metal to form the region into an eye with the groove opening inwardly into the eye so that the piece of sheet metal with the eye forms a first leaf. A pivot pin with a radially outwardly projecting thickened region is fitted and pressed into the eye such that the radially thickened region radially elastically widens the eye. Once the thickened region reaches the groove, the eye springs back so that the pivot pin is then captured held in the eye.

Abstract: An adjustable hinge for mounting a movable door element to a frame element has a plain leaf adapted to be secured to one of the elements and having at least one knuckle, a pintle passing through the knuckle along a pintle axis, and an adjustable leaf. This adjustable leaf has a plate formed with at least one knuckle aligned with the knuckle of the plain leaf and also traversed by the pintle, and a housing adapted to be secured to the other of the elements and formed with a slot receiving the plate. The slot forms a fulcrum for pivoting of the plate relative to the housing about an adjustment axis parallel to but offset from the pintle axis through a multiplicity of angularly offset positions. An adjustable element is provided for fixing the plate in the slot in any of the angularly offset positions. In addition the plate is displaceable parallel to the axis in the housing.
