Abstract

629,454. Lapping. TRIGGS, W. W. (Food Machinery Corporation). Nov. 4, 1947, No. 29419. [Class 60] [Also in Groups XXII, XXIV and XXVI] A helical piston rotor 30, for a meshing- screw pump, is lapped by the movement of the rotor in a nut 130, which reciprocates longitudinally between stops 125. When an arm 131 hits a stop 125 the driving motor 111 is reversed.
