Abstract

469,148. Concrete pumps. CHAIN BELT CO. April 8, 1936, No. 10316. Convention date, Oct. 12, 1935. [Class 102 (i)] [Also in Group XXVI] The inlet valve 23 and outlet valve 33 of a concrete pump are so arranged that the discharged concrete passes through both valves. The valves are of the oscillating type and partially or wholly close their respective pipes. The closing segment 25 of the inlet valve is so formed that it forces concrete into the cylinder during the opening movement. The inlet valve is operated by a connecting rod provided with two springs which are respectively compressed, by excessive resistance encountered by the valve during the opening and closing movements to permit shortening and lengthening respectively of the rod. The pump is mounted on a carriage 5. Specifications 412,282 and 455,093 are referred to.
