OBL-CUP.

SPECIFICATION forming part of Letters Patent No. 257,173, dated May 2, 1882.

Application filed December l0. 1881.

To all whom it may concern:

Be it known that I, JOHN G. MCBRIDE, of the city and county of Sacramento, in the State of California, have invented certain new and useful Improvements in Oil-Cups; and I do hereby declare that the following is a full, clear,

` and exact description thereof, reference being had to the accompanying drawings.

The object of my invention is to provide an oil-cup for lubricating journals and bearings in which the feed-regulating devices are all outside ofthe cup and below it, thus leaving the interior of the cup or oil-reservoir to be wholly occupied by the oil. The feed-regulating device I arrange below the oil reservoir or cup, either horizontally or at an angle to the passage which conducts the oil from the reservoir to the surface to be lubricated, in the manner hereinafter described, and pointed out in the claim.

Referring to the aceompanyin g drawings, Figure l is a vertical section with the valve open and held out from the seat. Fig. 2 is a section across the valve-rod, showing the lugs s and the slots s. Fig. 3 is a section ot' a portion shown in Fig. l', the parts being released, the spring expanded, and the valve closed.

Let A represent the cup or oilreservoir, which can be made in the usual manner and in any desired form. l

B is the tubular spindle, which supports the cup abovethe journalor surface tobelubricated, and through which the oil passes to the said j ournal or surface. At some point in the length of this spindle I apply the feed-regulating valve, which governs tbeflow oftheoil through the passage, and this valve I arrange at right angles to the passage, so that its handle, stem, or length will extend either horizontally or at an angle, instead of vertically up through the cup or reservoir, as heretofore. I can either apply it at some point between the bottom ofthe cup and the lower end of the spindle, or I can make the bottom of the cup thicker on one side and arrange the valve so that its spindle will pass through this thickened portion. In the latter case the valve will be very near the upper end ofthe oil-passage, and the handle or stem will project outside of the body of the cup. Various styles of valves could be used-such, for instance, as a rotary faucet-valve or a gate or cut-oli1 valve; but the best arrangement I have (No model.)

tried is a common globe-valve operated by a spring, as shown in the drawings, Fig. l. This arrangement permits me to use mydevice for regulating and preserving a set-feed shown and described in my Letters Patent No. 221,929, issued to me on the 25th dayT of November, 1879.- In the present instance I have represented the valve as applied below the bottom of the cup in the length of the spindle. The spindle I form with a globular enlargement upon it, and I make the hole or oil-passage e inthe upper half of the spindle, on one side ofthe hole or oil-passage in the lower half, w. I then connect the two passages by an inclined passage, z. In one side of the globular enlargement I make a hole leading to the inclined passage z. I then mount a conical plug or valve,f, so that it will stop up the passage or port a when it is closed down. rIhis valve has a spindle, g, passing outward at an upward angle through a hole in the cap or cover h, and a spring, t', surrounds the spindle, so that one end bears on the plug or valvef, while its opposite end bears against the inside of the cap h, thus serving to keep the plug or valvef on its seat or in any Xed position. When the plug or valve is closed no oil can pass down through the spindle.

On the outside ot' the cap or cover h, and around the hole through which the spindle passes, I make or form an annular ring, r, as described in my former patent heretofore mentioned, and in this ring I make the recesses or slots s of different depths, as described in that patent.

On the outer end of the screw-threaded spindle I secure the threaded boss or head t, on the under side of which are ribs or lugs s on a ring, s2, that enter the slots or recesses s in the ring r, so that by drawing the spindle outward and turning it so as to drop the ribs or lugs into the recesses corresponding to the feed desired the valve will be opened correspondingly. The oil will then flow down through the oil-passage to the surface to be lubricated. v

It will be noticed that this entire arrangement is similar to that described in my former patent, only I arrange the spindle and valve horizontally or at an angle, instead of vertically, and apply it below the oil-cup, thus leaving the interior of the oil cupor reservoir to be occupied solely by the oil.

IOO

2 v 25ans In the top ofthe cup A, I makean opening, through which theoilisintroduced into the cup, and this opening I stop with an ordinary screw plug or cap7 V. This leaves the top of the cup free from any projections, so that it is easily wiped and cleaned, and there is no danger of dirt or dust getting into the reservoir. By placing the mechanism for regulating the ow of oil in the side of the tube rather than down through the top of the oil-reservoir I attain this further advantage: The length of the spring is shortened and its liability to get out of place is greatly' diminished. Besides, when located in the reservoir, the surrounding lubricant, if of a stiff and hard character, is apt to obstruct the efficiency of the spring.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

. The valvef7 stem g, cap h, provided With the ringr, having recesses s,shortinterposed spring z', and cap t, having a ring, s2, providedlwith lugs s', the Whole being arranged in the side oi' the lubricator-stexli, and combined with said stem so as to be adapted for use With the short spring, as herein set forth.

In Witness whereof I have hereunto set my hand and seal.
