ABSTRACT:
4. A hinge to pivotally connect a door to a frame in a manner such that the door will close tightly without a latch, said hinge comprising a first portion and a second portion, said first portion having a first flange, a first ear, and a connection between said flange and said ear, one of said portions being attachable to the frame and the other portion being attachable to the door, said connection between said first flange and said first ear being of sufficient length to space the hinged end of the door from the frame in the closed position of the door when the door has been pivotally connected to the frame, said first portion being attachable along any part of said frame or said door, said second portion including a second flange, a second ear on one side of said second flange connected to said second flange, said first ear and said second ear being pivotally connected by a hinge pin, guide means extending from said second flange, a plunger [pressure member] carried by said second portion and guided with the aid of said guide means in a direction toward and away from said hinge pin, spring means carried by said second portion urging said plunger [pressure member] toward said hinge pin, said ear of said first portion having an arcuate portion and an engageable edge to be engaged by said plunger, [pressure member] said edge being positioned so that the force of said spring means acting through said plunger [pressure member] and said edge can be directed to one side of said hinge pin to produce a torque tending to move the door beyond its closed position, when the door is closed, and said arcuate portion being continuous from one end thereof at its juncture with said edge to its other end and being of sufficient length to have portions thereof receive [positioned so that] the force of said spring means acting through said plunger against said arcuate portion and [pressure member can be] directed through said hinge pin when said door is in any open position between the near-closed position and the fully open position and said plunger [pressure member] is spaced from said edge.
