UNITED STATES PATENT OFFICE.
AUGUST MLITZ, QF CHARLOTTENBURG, GERMANY.
PISTON LUBRIGATIN'G-PUMP.
T0 aZZ whom it may concern Be it known that 1, AUGUST MLrrz, a subject of the German Emperor, residing at Charlottenburg, near Berlin, in the Kingdom of Prussia, Germany, have invented a new and useful Piston LubricatingPump, of which the following is a specification.
My invention relates to a piston lubricating pump.
In order that one may not be compelled to change the adjustment in cases where an increased supply of oil is required either suddenly or for a limited time, there is, according to the invention, connected a pumping arrangement worked by hand with the automatic pumping arrangement. For this purpose the piston or a portion thereof may be attached to an auxiliary piston-rod which is provided with a suitable head and by springs so arranged within a tube connected with the driving mechanism that in general the piston will be driven by the driving mechanism; but in cases where momentarily a larger supply is required the piston can, independently of the driving mechanism, be driven by hand.
The drawing shows a form of execution of the invention.
Figure 1 shows a cross section of a pump with single-working pistons. Fig. 2 represents a front View of the same with partsection through the oil-vessel.
By a crank-shaft a are driven pistons I). These pistons are connected with the eccentric straps 0 of the crank shaft by means of, adjustable socket members cZ held in the eccentric straps c by means of screw threads and containing the lower part of the auxiliary piston rods Z and the pistons b. The springs e rest at one end on the flanges of the socket members d and at other against the washers 9 held in place by the pins f secured to the auxiliary piston rods Z. The flange on the socket member and the washer g serve as cheek plates between which may be compressed the spring 6 which serves Specification of Letters Patent.
Application filed December 16, 1909.
Patented Jan. 16, 1912.
Serial No. 533,435.
to hold the piston Z) yieldingly pressed against the lower end of the socket member (Z. Normally the pistons b are operated by the crank shaft a. An adjustment of the pump may be made by screwing the socket member d in either direction whereby more or less of the port it is exposed for the entry of oil. Oil is pumped only during that part of the stroke of the piston b after the port it has been closed, by the piston. The aperture i is arranged in the lower part of the pump cylinder and serves as an outlet for the oil. At the lower end of the aperture 71 is located the check valve is to prevent back flow of oil. In the event of an increased supply of oil being momentarily required, piston rod Z is means of head m so that the supply conduit is provided with a larger quantity of oil in consequence of the increased number of piston strokes. On piston rod Z being pressed down, pin f which is fixed to the piston rod moves in slits of the socket member (Z.
lVhat I do claim as my invention, and desire to secure by Letters Patent is:
In a lubricating pump the combination of a pump-cylinder, a piston, a piston rod carrying the piston, a driving mechanism, actuating the piston a socket member adjustably connected with the driving mechanism the lower part of the piston rod being arranged within the socket member said socket member being provided with a flange, a confining member on the piston rod, a spring arranged between the flange and confining member whereby the piston is pressed against the under side of the socket member, substantially as and for the purpose set forth.
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
AUGUST MLITZ.
