Abstract

121,570. Gaymer, J. H. June 15, 1918. Safety valves.-A relief valve of the kind described in Specifica.- tion 109,526, in which the valve member is mounted on a piston sliding in a cylinder arranged on the outlet side of the valve, has the outlet apertures formed in the bottom of the cylinder, and has the loading spring adjusted by a nut slidably mounted in the cylinder and engaged by a screw carried by a cap rotatably mounted on the cylinder. The valve member i is secured to the piston j by a metal frame k having a flange m adapted to be held against the piston by lugs l passed through slots in the piston and then bent over. The cylinder e has slots o adapted to be engaged by projections n on the piston and by lugs q on a nut p bearing against the loading spring v. The -nut v is reciprocated by a screw r carried by a cap s adapted to rotate on the cylinder. The lower end of the cap is fitted with pins t adapted to engage under the influence of the loading spring, one or other of notches u<1> formed along the upper surface of a groove u in the valve body, to lock the adjustment against accidental movement.
