Gate hinge composition

Hinge means for mounting the gate to a fence post within an opening in the fence for gravitational closing from an open position, comprising upper and lower supports for attachment to the fence post and upper and lower hangers for attachment to the gate post, said supports and hangers being adjustably movable on the posts for clamping thereto at corresponding spacing, each support comprising an arm, a pintle pin at one end and two-part clamping means at the other end for encircling the fence post so arranged that the axis of the pintle pin and the axis of the two-part clamping means lie on the longitudinal center line of the arm and are perpendicular thereto, said two-part clamping means comprising at said one end of the arm a transverse part having a substantially half-cylindrical surface which is symmetrical with respect to the center line of the arm, at the opposite ends of which are holes, the axes of which are parallel to the axis of the center line of the arm, a U-shaped band embodying a substantially half-circular part which, in conjunction with the substantially half-cylindrical surface of the transverse part, provides a clamping collar for clamping engagement with the fence post and at its opposite ends straight portions for engagement with said holes and means for securing the straight portions within said holes, said upper hanger comprising two parts of symmetrical configuration adapted to be bolted face-to-face and each part containing longitudinally spaced substantially half-circular openings defining half-circular surfaces of different diameter which collectively define, when the parts are bolted together, a collar for clamping engagement with the gate post and a bearing opening for pivotally receiving the pintle pin of the upper support and said lower hanger comprising two parts adapted to be bolted face-to-face, one of said parts containing longitudinally spaced substantially half-circular openings defining half-circular surfaces corresponding in spacing and size to those of the parts of the upper hanger such that the two halves of the upper hanger and the one-half of the lower hanger are identical and the other one of the parts of the lower hanger containing a half-circular opening corresponding to said substantially half-circular opening of larger diameter in the one part and a substantially half-circular nub protruding from its face for engagement within the substantially half-circular opening of smaller diameter in the one part, and a limb extending from said other one of the parts at an angle to the center line defined by the faces of the parts beyond and laterally of the center line having at its distal end a bearing opening for pivotally receiving the pintle pin of the lower support so that when the gate is hung, a projection of the axis of the pintle pin of the lower support on a line containing the centers of the posts is closer to the axis of the fence post than is the pintle pin on the upper support and that the center lines of the upper and lower hangers coincide with the vertical plane containing the vertical axes of the posts so that the plane of the gate coincides with the plane of the fence when the gate is closed and, when in said closed position, the axis of the lower pintle pin is situated laterally of said plane.
