ABSTRACT:
One of a pair of hinge leaves has an integral open outer loop extending along one edge and the other leaf has an integral inner loop extending along one edge and disposed inside the outer loop. The inner loop is mounted on a hinge pin extending through it and provided with longitudinally spaced exposed areas encircled and engaged by spacing members rigidly mounted in the outer loop to hold the pin in predetermined position in that loop. The opposed surfaces of the two loops are held apart by the pin and spacing members to prevent the loops from rubbing together when the hinge is opened and closed. By making the hinge pin hollow and extending a torsion rod through it, with one end of the rod attached to the inner loop and the opposite end connected to the outer loop, the rod will be twisted when the hinge is opened and will close the hinge when it is released.
