Abstract

553,874. Reciprocating pumps. ABBEY, A. (Bliss Co., E. W.). Nov. 6, 1941, No. 14324. [Class 102 (i)] [Also in Groups XXII and XXVI] A reciprocating pump comprises a plunger formed in two parts 47, 49 normally kept apart by a strong spring 50 to an extent limited by the screw 52. When the pressure in the pump rises, the part 49 ceases to reciprocate, the spring taking up the movement of the part 47.
