OIL-CUP.

.SPECIPI CATION forming part of Letters Patent No. 339,489, dated April 6, 1886.

Application tiled November 24, 1885. Serial No. 183,864.

To all whom it may concern:

Be it known that I, FRANK Oscnn SLANK- ER, of Pomona, in the county of Los Angeles and State of California, have invented a new and Improved Oil-Cup, of which the following is a full, clear, and exact description.

My invention relates to oil-cups adapted to supply oil for lubricating the bearings of shafts and other moving parts of machinery, IO and has for its object to provide a simple, inexpensive, and effective device of this nature which will keep the oil free from dust and grit and deliver the oil in measured quantities.

The invention consists in certain novel featu res of construction and combinations of parts of the oil-cup, all as hereinafter fully set forth.

Reference is to be had to the accompanying drawings, forming part of this specification, 20 in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a vertical sectional elevation of my improved oil-cup, shown closed and as adjusted to a hearing, which, also, is shown in section; and Fig. 2 is a vertical sectional elevation of the oil-cup, showing its operation in ejecting the oil.

The body portion A of the oil-cup has a screw-neck, B, at its lower end, by which it may be attached to a bearing, G, as shown in Fig. 1. The top of the cup is closed by a cap, D, which, preferably, is made to screw into the body of the cup, and is apertured centrally to provide a bearing for the spindle E, which has at its lower extremity a plugvalve, F, which is connected to the end of the spindle by a stem, f, a shoulder, 6, thus being formed on the spindle next the stem.

The lower end of the neck B is formed with a recess, b, which provides a seat for the valve F, and an aperture, 12, leads from the recess b to the oil-chamber G, which is formed in the neck B immediately under the shoulder e of the spindle E. A spring, H, placed on 45 the spindle between a pin, h, in the spindle and the bottom of the body A of the oil-cup, acts normally to lift the spindle and hold the valve 13 to its seat to prevent escape of oil from the cup.

When the spindle E is pressed downward (No model.)

by the finger and against the tension of the spring H from the position shown in Fig. 1 to that shown in Fig. 2, the plug-valve F will be lowered to open the outlet Z2, and thespindie-shoulder 'e will simultaneously enter the oil-chamber G and eject all the oil which had filled into the chamber from the aperture b onto the shaft or moving part fitted in the bearing 0. \Vhen the spindle is released, the spring H will instantly force it upward and close the valve F and cut off the flow of oil from the chamber G until the next time the spindle is depressed. The shoulder a of the spindle, when raised, stands about level with the top of the oilchamber G, allowing the oil to flow past it to fill the chamber, and instantly cutting off the flow to the chamber from the body of the cup as the spindle begins its downward movement; hence the size of the oilchamber G governs the quantity of oil dis- 0 charged from the cup at each downstroke of the spindle, and by making the oil-chamber larger or smaller the discharge of the oil from the cup may be accurately regulated as the surfaces to be lubricated may require.

The body of the oil-cup may be made of glass, metal, or'other suitable material, and of any desired size. On removing the cap Dthe oil may be filled into the cup or replenished at any time.

It is evident that the oil is discharged from the cup by the positive action of the spindle, which forms a plunger; hence the flow of oil from the cup will certainly follow the depression of the spindle, and the oil in the cup is 8:; always under cover; hence the oil fed to the bearings will be free from dust and grit, and will have the best lubricating effect.

Whenever the spindle E is depressed, the stem f of the valve F will clear the oil-passage 0 b, to insure the discharge of the oil from the cup.

Having thus I claim as new, ters Patent, is-

1. An oil-cup comprising a body or oil-receiving vessel, A, provided with a subjacent oil-chamber, G, an outlet, 1), and a valve-seat,

1), below said outlet, and a spring-pressed spindle, E, having a valve, F, at its lower end and ICC described my invention, what and desire to secure by Letadapted to close the outlet b, and said spindle H, on the spindle, and said spindle having an 10 having a shoulder at e, forming a plunger to oil-ejecting shoulder at e,and avalve,F,adapteject the oil from the chamber G when the ed to close the outlet 12, substantially as herespindle is depressed substantially as herein in set forth. 5 set forth.

2. The combination, in an oil-cup, of the FRANKOSOAR SLANKER body or vessel A, having a screw-neck, B, and Witnesses: a removable cap, D, an oil-chamber, G, in the H. MoOoMAs, neck B, and an outlet, b,aspind1e, E,aspring, T. C. THOMAS.
