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. |
