' To all whom it may concern:
- Be it known that I, EUGEN;WOERNER, a subject of the Emperor of Germany, residing at and whose post-oflice address is Cannstatt, Burgstrasse 7 Germany, have invented certain new and useful Improvements in Pumps for Lubricating Systems;
and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in use the same.
"The present invention relates to pumps for lubricating systems for forcing oil fori the like to thefriction surfaces of machines,
and it relatesparticularly to an organization of this kind having in its preferred form a plurality of piston pumps disposed in circular arrangement about a rotatable: actuating and valve member provided with mechanism for periodically reciprocating all? the pistons and having passages for the sup-s ply of oil from a lubricant supply conduit and for the discharge of the oil to the individual lubricant discharge conduits. v Furthermore, the pump cylinders are parallel with the actuating and valve member so that the actuating mechanism for reciprocating all the pistons may consist of a single cam disk, preferably having one or more elevated level portions and a-corresponding number of depressed portions connected at diametrically opposite points by inclined portions of the desired angular extent and slope to bring about the desired cycle of operations. By these means-an efi'ective organization for supplying lubricant to any number of discharge conduits is made possible by'a simple and reliable construction oper ated by a single rotatable element. In this way the parts shown in my copending applications, Serial No. 581,47 9, filed September 12,1910, and Serial No. 652,519, filed October43, 1911, for turning the pistons of the pumps to control the passage of oil from the source of supply to the discharge con-- duits and for preventing the return of the oil to the reservoir during the pressure stroke of the pumps are eli'minatedywhil ehe art to which it appertains to make and;
the construction of driving mechanism common in e he yp of P p i I' ir; pose 1s considerably simplified. In the accompanying'dr'awin s illustrating the preferred embodiment w thin m y'iiivention, Figure 1 represents a centralvertical section of an'organization havingf for.

periodically registers" with the individual supply pa age me: me, m4: 5; and s ofthe pump cylinders to form "a suctionconduitfrorh the oil reservoir for each pump in turn during the suction stroke'of'the core -pQnsiiAgpi onh v ert a passage 71 is so disposed in the member 0 are periodilevel portion t and a depressed level portion cally connect in turn the passages m and o of that pump cylinder which is diametrically opposite the pump then in communication with the oil reservoir. The discharge passages 0 0 0 0 0 and 0 are opposite the dlschal'ge Passages 91, 92,13, 94, Q5, and 96 and communicate therewith across the reduced portions 72 32 32 19 p and p of the respective pistons, whereupon the oil is periodically discharged through the lubricant discharge conduits 1),, v '0 '0 '0 and 0, to the friction surfaces of the machine to be lubricated during the pressure stroke of the corresponding piston.
The operation of the organization will now be described. In the position shown in Fig. 3, the piston b, is .at the bottom of its reciprocation, ready to start its upward or suction stroke as a result of the engagement between its yoke and the depressed portion of the cam disk f at the base of the inclined portion 7'. The passage Z in the actuating and valve member 0 just starts to register with the passage m at the bottom of the cylinder. The inclined portion r of the actuating cam disk lifts the piston b, to the top of its suction stroke, which ends when the passage Z has the position shown in the broken lines in Fig. 3. The oil which is drawn into the pump cylinder below the piston b, from the oil reservoir through the lubricant supply conduit (1 and the passages h, is, l, and m as a result of a suction stroke of the piston, is entrapped in the cylinder until the member 0 is turned almost a half rotation, whereupon the vertical passage n then connects the passages n, and 0,. At this time the yoke of piston b engages the downwardly inclined portion .5 of the actuating cam disk 7, so that the piston 6 then starts to move down and thereby forces the oil, which was previously entrapped below piston 6 through the passages m 01., and 9, and by way of the reduced portion p, of
the piston into the lubricant discharge con-' duit 2),. When the piston 6 reaches its lowes't position, it remains idle until the upwardly inclined portion 'rof the cam again engages the yoke, whereupon the described cycle is again started. The other pistons have the same cycle of operation as 6 but in the case of the six pumps shown as an example, the successive cycles are displaced 60 from each other, so that diametrically opposite pumps as b, and .b, are half a cycle apart at all times. In the example illustrated, each piston is given a suction stroke and a pressure stroke during each rotation of the actuating and valve member a so that each lubricant discharge conduit receives a discharge of cil'once in each rotation, or all together a total of six discharges.
It will be apparent that the number of cycles performe by each piston during a supply and discharge passages, a reoiproca-.
tive piston in the cylinder provided with a passage arranged to complete the discharge passage through the cylinder during the pressure stroke of the piston, a source of lubricantsupply, and a valve member designed to establishcommunication between the source of supply and the supply passage of the cylinder during the suction stroke of the piston and to establish communication between the supply and discharge passages of the cylinder during the pressure stroke of the piston; substantially as described.
2. In force pump mechanism for lubricating systems, a plurality of pump cylinders provided each with a supply passage and discharge passages, a reciprocative piston arranged in each cylinder and provided with a passage adapted to establish, communication between the discharge passages in the cylinder, a source of lubricant supply, an individual lubricant discharge conduit for each pump, and an actuating and valve member having mechanism for reciprocating the pistons in order, said member containing a passage adapted to establish communication between the source of supply and the supply passage during the suction stroke of each piston, whereby lubricant is drawn into the corresponding cylinder, and also containing another passage adapted to establish communication between the supply passage in each cylinder and the dischar e conduit through the discharge passages 1n that cylinder and the passage in the piston during the pressure stroke of the piston, whereby the lubricant is then forced into the discharge conduit; substantially as described.
3. In a force pump for lubricating systerns, a lubricant supply conduit, a lubricant discharge conduit, a pump cylinder having a supply passage near the bottom and discharge passages above the supply passage in registry with the dischargemonduit, a reciprocative piston in the pum cylinder having a portion adapted to esta lish communication between the discharge passages in the cylinder, and a rotatable actuating and valve member provided with mechanism for reciprocating the piston, said member having an annular groove registerin with the supply conduit, a radial passage adapted toregister with the-supply passage in the inder during the pressure stroke of the cylinder during the suction stroke of the pump; substantially as described.
