Abstract
Abstract A hinge is described having a first plate consisting of two leaves which form at their end portions a barrel and an awl member received within the barrel. A second plate is then mounted on the awl member so that the second plate is contained within a plane which is parallel to the plane containing the longitudinal axis of the awl member. The diameter of the awl member is slightly larger than the diameter of the barrel and when the plates are mounted with screws, the diameter of the barrel will be further restricted so that friction will control operation of the hinge.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
102 words
A hinge comprising: first and second mounting plates, said second plate having upper and lower leaves and an end portion of each defining an integral barrel having a predetermined inside diameter so that when the leaves are drawn together, the diameter will be restricted, said plates having holes therethrough for mounting screws; a cylindrical awl having a diameter greater than the inside diameter of the barrel rotatably mounted therein, an end of said awl being attached to an end of said first plate, the longitudinal axis of said awl being disposed in a plane parallel to the plane containing said first plate.
Claim 2
Dependent Claim
102 words
A hinge comprising: first and second mounting plates, said second plate having upper and lower leaves and an end portion of each defining an integral barrel having a predetermined inside diameter so that when the leaves are drawn together, the diameter will be restricted, said plates having holes therethrough for mounting screws; a cylindrical awl having a diameter greater than the inside diameter of the barrel rotatably mounted therein, an end of said awl being attached to an end of said first plate, the longitudinal axis of said awl being disposed in a plane parallel to the plane containing said first plate.
Claim 3
Dependent Claim
13 words
The hinge of claim 1 wherein said awl and first plate are integral.
Claim 4
Dependent Claim
22 words
The hinge of claim 1 wherein the longitudinal axis of said awl is disposed in the same plane containing said first plate.
Claim 5
Dependent Claim
