Abstract

407,075. Reciprocating-cylinder pumps. ROLPH, W. M., 1, Dover Street, London. Sept. 8, 1932, No. 25091. Addition to 398,253. [Class 102 (i).] In order to adapt the pump described in the parent Specification for use with ink or other corrosive liquid the return spring 8 is arranged externally to the stem 1 of the piston head 3 and the pump parts are made of a non-metallic material, e.g. ebonite. The stem 1 screws into a member 11, which is attached to the mouth of the bottle, and carries the suction pipe 14, and contains the suction valve 13 and the discharge valve 17. A member 9 surrounding the stem 1 carries a casing 20 enclosing the spring 8, which bears on a shoulder on the moving cylinder 5. The stroke of the cylinder is limited by a screwed ring 6. The flexible discharge pipe 18, when not in use, is held by a clip 21 on the cylinder 5. Leakage into the casing 20 is returned to suction by a passage 22.
