Abstract

1,022,269. Reciprocating pumps. NECCHI S. p. A. Jan. 29, 1964 [April 5, 1963], No. 3799/64. Heading F1A. An oil circulating pump for a sewing machine comprises a plunger 24 which reciprocates and oscillates about its own axis in a cylinder 29. The end of the plunger has a cut-away portion 26 which alternately opens and closes the ports 36, 37 as it oscillates. The pump draws lubricant from a reservoir in the base of the sewing machine and a cooler is provided in the return line to the reservoir (Fig. 6, not shown). A shaft 9 carries an eccentric 8 whose rotation imparts an oscillatory and rotary movement to the plunger 24 and to hooks 3, 3<SP>1</SP> via crank mechanisms 13, 15, 17 and 14, 16, 18.
