To rtl/Z whom, t 'may concern,.-

Be it known that I, Lewis GLnAsoN, a citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented new and useful Improvements in Oil-Cups, of which the following is a specification.

My invention relates to improvements in lubricators; and its object is to provide an oilcup whereby a spring-pressed inlet-closure is provided and is adapted to cooperate with means confiningand guiding a cut-off valve, whereby a very simple construction of few parts may be provided and the said parts held in position by the pressure of a single spring.

My improvements are adapted to be applied to an oil-cup particularly adapted for use on mechanisms receiving sufiicient momentum to move the ball-valve which effects the cutoff, as above referred to, and particularly to such parts as cross-head guides on locomotives and other parts which may have a jarring motion and also motor-bearings to trolley-cars, &c.

My invention is embodied in the device shown and illustrated in the accompanying drawing, which drawing represents a central vertical section of my improved oil-cup.

In the drawing', 1 is the base of the oil-cup, adapted to be mounted upon the part to be lubricated and communicating,l with said part by a central channel or passageway 2. From this base 1 rises a cylindrical wall 3, forming the chamber' of the oil-cup and provided near its upper end with interior screw-threads A, by which a screw-cap 5 is adapted to be se- In the central portion of this capis a sliding plugvalve 6, having an upper disk portion 7 closely fitting the inner wall of the cap 5 and having a curved or semispherical body also closely conforming to the correspondingly-curved interior of the cap, whereby the inlet through the cap and the oil-containing chamber of the body is kept tightly closed when the valve is in its extreme upper position. The valve is kept pressed to such position by a coiled spring' 9, having its upper end seated within a recess 10, formed in the body of the valve 6, and having its lower end surrounding and supported by astud 11, rising from and formrests upon the bottom of the oil-cup.

ing part of a ball-cage 12, which has a iiat upper ledge 13, on which rests a strainer 14, whilea similar strainer 15 surrounds the lower portion of the ball-cage. Between these two strainers isconiined a mass of natural wool which serves as a feed-controlling medium between the oil-chamber and the outlet-passage leading to the part to be lubricated.

The ball-cage 12 is semispherical in its interior surface and serves to coniine within a limited radius of movement a ball-valve 16, seated in the curved depression 17 of the oilcup base and adapted to close theoutlet-passage 2 when the oil-cup is at rest, so that the feed of the oil from the chamber will be cut ofi". The curved ball-cage has base 18, which Passage-holes 19 are formed through the lower portion of the ball-cage, so as to permit the passage of oil from the feed-controlling body of wool to the outlet-passage 2.

The pressure of the spring not only serves to keep the valve 6 normally closed, but also to firmly retain the ball-cage and the strainers with their contained feed-controlling body of wool firmly in place in the bottom of the oil-cup.

When it is desired to supply the cup with oil, it is merely necessary to press down the spring-pressed valve and pass the oil into the cup. r1`he parts can be readily removed for cleaning or repair.

Having thus described my invention, what I claim is- 1. In an oil-cup, in combination with a closingfvalve for the cup, a spring for said valve, a cut-off valve and a cut-olf vaive'cage, said valve-cage being pressed upon by said spring to hold it to its seat, substantially as described.

2. In an oil-cup, in combination with a valve provided with a recess and adapted to close the entrance to said cup, a coiled spring iitted at one end in said recess, a cut-off valvelcage and a stud rising from said valve-cage, and engaging the other end of said spring, substantially as described.

3. In an oil-cup, in combination with a spring-pressed closure-valve, a spring for said valve, a cut-ofi' ball-valve in the lower part of said cup, a cage for said ball-valve, separate IOO straners mounted on said Cage and a feed l In testimony whereofl affix my signature in controlllng mecllum between the salcl stralnpresence of two subscribing wlnesses. ers, Saud ball-Valve cage adapted to engage and be pressed upon by said spring, whereby said LEVlb GLEASON' 5 cage and the straners are held in place at the VVbnesses:
