Abstract
506,839. Piston - rings ; stuffing - box packing. OUBRIDGE, W. A. Jan. 1, 1938, No. 4. [Classes 122 (i) and 122 (v)] Piston or pump shaft packing-rings a, of the double or multiple coil have a spring backing means b which bears against the bottom of the groove and exerts a uniform radial pressure in all directions on the packing- ring. Where made of more than two coils, the intermediate coil or coils a<1> may be waveshaped to press the plane coil against the lands of the groove. The free ends of the ring are restrained from fouling ports in the cylinder &c. by engagement behind the bridge piece e. The outer edges of the free ends may be chamfered.
