OIL CUP.

Application filled April 10, 1924. Serial No. 705,580.

T 0 all whom it may concern:

, Be it known that 1, San S. RUNDELL, a citizen of the United States, residing at Bogalusa, in the county of Washington and State of Louisiana, have invented a new and useful Oil Cup, of which the following is a specification.

This invention aims to provide novel means whereby heavy grease and liquid oil may be supplied to a part to be lubricated.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

Although a preferred embodiment of the invention has been shown, it will be understood that a mechanic, working within the scope of what is claimed, may make changes, without departing from the spirit of the invention.

In the drawings :-Figure 1 shows in longitudinal section, a device constructed in accordance with the invention; Figure 2 is a cross section on the line 22 of Figure l; and Figure 3 is a fragmental elevation showing a slight alteration, in the form depicted in Figure 1.

The device comprises a casing, denoted generally by the numeral 1, the casing comprising a tubular body 2, secured in any desired way, as at 3, to the member 4 which is to be lubricated, the said member having an opening 5, through which both the heavy grease and the liquid lubricant are dis charged For the sake of strength, the body 2 has an enlarged upper end 6 into which is threaded closure '7 for the body 2, the closure having an outstanding flange 8 engaging the part 6 oi? the body 2. The closure 7 is provided with a chamber 9 for liquid oil. A tubular guide 10 is secured by threading or otherwise in the inner end of the closure 7, the liquid oil fiinding its way from the chamber 9 into the tubular guide or discharge member 10, through a small passage 11 fashioned in the closure 7 at the inner end of the chamber 9. The combined guide and discharge member 10 has a tapered lower end 12 which extends into the opening 5 in the member 4:, without filling and closing the said opening. If desired, and as shown in Figure 3, the guide tube and discharge member may extend through the opening in the member to be lubricated; and in Figure 3, parts hereinbefore described are designated by numerals previously used, with the suflix a.

A plunger 14, in the form of a disk, fits closely but slidably in the tubular body 2 and is mounted slidably on the tubular discharge member 10. The plunger 14: has a hub 15, about which is engaged one end of .a helical compression spring 16, surroundingthe discharge member 10, the other end of the spring being received in a seat 17 formed in the member 7. The spring is shown in Figure 1 as partly compressed, and as the spring expands, the downward or inward movement of the plunger 1% is limited by one or more stops 18 on the discharge member 10, the construction being such that when the device is assembled shown in Figure 1, but before the body 2 is connected to the member 1, the spring 16 cannot force the plunger out of the tubular body 2, the device thus being held assembled, ready for mounting on the part 1 which is to be lubricated.

The casing 1 includes an inlet member 19, threaded into the chamber 9 of the closure 7 and provided with an enlarged head 20 bearing upon the outer end of the closure 7. The inlet member 19 has a chamber 21 communicating with the chamber 9 of the closure 7, there being an inlet opening 22 in the member 19, and the member 19 being provided with a valve seat 23 located between the opening 22 and the chamber 21.

The opening 22 in the inlet member 19 is controlled by a valve 24, adapted to cooperate with the seat 23 and provided with a hub 25 from which projects a cleaner 26, in the form of a rod, adapted to reciprocate in the tapered end 1.2 of the discharge mem ber 10, for the purpose of removing 0bstructions. A compression spring 27 surrounds the hub 25 of the valve 24, one end of the spring engaging the valve, and the other end of the spring engaging the closure 7 at the inner end of the chamber 9.

v In practical operation, the closure 7 and parts carried thereby are removed from the body 2, and the body is filled with heavy grease. The closure 7 is replaced, the

plunger 14': resting on top of the grease, and

the spring 16 being compressed. The spring 16 expanding, will tend to move the plunger 14 inwardly, and the plunger will force the heavy grease through the opening 5 in the member 4. The valve 24 may be forced inwardly by the spout of an oil can, "and liquid oil may be shot into the chanibers21 and 9, the liquid oil flowing through the passage 11, and through the -disch-arge member "'10, to the place "Where lubrication is required. The spring 27 tends to hold the valve 24- in closed position, and each time that the valve 24 is moved, the rod 26 will be reciprocated, thereby cleaning out the reduced end 12 of the discharge member a s 1 item I claim 7 v '1. In a device of the class described, a casing having an inner chamber for heavy grease, and an outer chamber for light grease, a discharge member communicating With the outer chamber and extended throughthe inner chamber, a plunger "slid- "dlo'sure for the outer chamber, spring means for holding the valve seated, and a cleaner carried by the valve and operating in the discharge member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
