27,768. Zeidler, L. Dec. 21. Lubricating pumps.-A lubricating-pump, of the type in which a reciprocating piston oscillating about its axis serves as a valve, is fitted with a "stepped" piston p having grooves b by means of which the separate barrels are put alternatively into communication with the suction and delivery passages. The piston is reciprocated by a lever h, which is oscillated by means of a crank-pin k; and the axial oscillation of the piston is produced by means of a rack carried by a sliding member q, which is reciprocated by a cam on the same shaft as the crank-pin k.
