Abstract

605,924. Gate operating-appliances; hinges. STONE, H. A., and BRIDGER, W. C. H. Jan. 8, 1947, No. 9080/46. [Classes 65 (i) and 65 (ii)] A gate operating-appliance or spring hinge of the kind having a movable part 28 which carries a spring 27 adapted to move over a cam or the like on a fixed part 29, the spring being stressed when the gate is opened, comprises two abutments on the fixed part. The abutments, formed by an edge 31 and the nearer edge of a slot 32, are situated one on each side of the pivot 30 and are adapted to engage opposite sides of the spring when the gate is closed, thus constituting a stop for the latter in its closed position. The gate is held in its open position when the spring, after relaxing from the condition of maximum stress, moves into engagement with the side of the fixed part.
