An improved hinge construction is provided having cam and spring means for maintaining it in its open and/or closed positions and importantly, having parts enabling it to be adjusted as to its positioning between a door and a door frame after it has been secured in position therebetween. Adjustment in its heighth and lateral relationships may be independently accomplished. A screw is carried by the boss of a screw-on mounting plate and cooperates with a so-called driving dog to effect lateral adjustment between the mounting place and a swing or operating arm and thus, between the door frame and the door, itself. Heighth adjustment is accomplished independently by loosening a mounting or fastening screw that is used to secure the swing arm to the boss, sufficiently to enable cross adjustment between cooperating serrations carried by them. The lateral adjustment is accomplished, while retaining the cooperating serrations in their previously aligned relation, by moving the elements along rather than across such serrations.
