Abstract
A hinge assembly for a manual or automatic air brake valve test fixture that includes a secondary test plate to which a valve device to be tested is mounted from a front load position and then rotated to its usual side location for clamping to the primary test plate, thereby relieving the tester of physical strain encountered heretofore in mounting the valve in a side load position. The hinge assembly is spring-loaded to obtain even, face-to-face engagement of the mating surfaces of the primary and secondary test plates and thereby assure the integrity of the pressure seal therebetween.
