ABSTRACT:
Aligned hollow knuckles on a pair of hinge leaves form a cylindrical barrel. Spaced plugs inserted into each end of the barrel serve to keep the knuckles from separating and act as a pivot pin for the hinge. Bifurcated reduced inner portions of the plugs receive the ends of a coil spring therebetween. One plug is permanently secured to a knuckle of one hinge leaf. A pin secured to the other knuckle extends into the barrel and is carried within an annular groove in the adjacent plug. A stop in the groove limits the travel of the pin. Minimum tension is provided at all times in the hinge by the initial setting of the stops with respect to the pin. Additional tension is provided by a plug rotating means together with a second pin engageable with recesses in the plug and a bore in the hinge knuckle.
