SPECIFICATION forming part 0f Letters Patent No. 478,224, dated July 5, 1892. Application tiled March 5, 1892. Serial No. 423.945. (No model.)

To all whom, it may concern; Y

Be it known that we, FRANCIS JOHN COL and GEORGE BLAGDEN HAzLEHURs'r, citizens` of the United States, and residents of the city of Baltimore, State of Maryland, haveinvent-v ed certain new and useful Improvements in tion through the oil-cup. Fig. 2 is a plan of the exterior of the oil-cup. Fig. 3 is an elevation of the adjustable cap for regulating the feed. Fig. 4 is a plan of the same.V Fig. 5 is an elevation of the central shan k or valvecase with the oil-inletlshown in full. Fig. 6 is a side elevation of the saine turned at an angle of ninety degrees with the previous position. Fig. 7 is a plan of the same.

A is a cup arranged to contain oil.

B is a cap or cover screwed into the top of the cup.

D is an independent stein or shank containing the spindle and provided on its end with a screw-thread for fastening the cup on the part to which it is to be attached, and having a thread on its upper end upon which is screwed the adjustable cap for regulating the feed.

E is a channelfway or hole cut through the center of said stem transversely and of a size larger than the valve-stein on the interior of the shank.

F is a hole through the center of the stein D of smaller size below the transverse hole E than above it, andhaving a valve seated upon its upper end at the point where it cnters the hole E from below.

G is a valve-stem or vibrating spindle which forms a valve at its lower end. The lower portion is smaller than the upper part and enters the hole F, which is below the oil-inlet E, while its upper portion is larger and about fills the larger hole in the upper portion of sition of the cap and its yoke.

seat. -it will be impossible to remove the oil-cup cap J, which is cylindrical at its lower por- Y tion, open at the top, and having a yoke K across the top connecting the two sides. This cap' may of course be made of any other shape so long as it has an internal screw. This yoke is quite high, so as to stand considerably above the cylindrical portion of the cap. The top of the valve stem or rod Grests or stands just below the under side of the yoke K, and the amount'of motion permitted to the valve-stem is dependent upon the po- The cylindrical portion of the cap J is split on one side at the pointmarked L. This slit is somewhat open, so that by pinching the cylindrical portion of the cap'it may be made to it tightly uponthe thread I-I, and be made to retain its position while the machinery is in operation.

The operation of the device is as follows: Vhen the oil-cup is to be attached to a piece of machinery-such as a locomotive, for instance-the oil-cup is put on and the spindle screwed through its bottom into the hole provided for it. A specially-constructed wrench having a deep socket is then placed over the shank and it is screwed down firmly onto its When this is done, it will be seen that without taking it apart and also without this special wrench to take hold of the stem. This difficulty avoids the loss of these oilcups by theft, which frequently happens in the forms which can be easily removed with the ordinary wrench. The spindle or valvelstem is then placed in the center of the stern with its shoulder bearing upon the Valve-stein.. The cap is then screwed on, the threads fitting tightly upon the thread H on the upper end of the stem D, so asto hold it'rigidly in any position at which it may be placed. It should be so adjusted that a small amount of play, from one thirty-second to one-sixteenth of an inch, be left between the top of the spindle IOO and the under side of the yoke, so as to permit any desired amount of play in the valvespindle. The cup is then filled with oil and the cap screwed in place. W'hen the niachinery is in rotary motion the rapid up-and down motion of the crank will canse a similar throw of the spindle and permit oil to flow through the transverse channel-way E, through the valve and the inlet-opening F to the bearing. The feed of the spindle may be easily adjusted by a simple turn or part turn of the adjustable cap and the amount of feed of the spindle can be seen at a glance upon taking off the top of the oilcup. The transverse hole E, being at the bottom of t-he cup instead of the top, as is usual in many cases, permits the oil-cup to be drained to the very bottom.

In most oil-cups heretofore made the cup and stem by which it is screwed to the machinery are cast in one piece and are both made of brass. Te have found it to be of advantage 1o make the cup of brass; but the interior stem, by which the cup is held in place and through which the oil is fed to the hearing, we make of wrought-iron or steel. This greatly strengthens the mechanism and mak es it difficult to knock it off or remove it. The cap of my oilcup is solid and has no apertures in it. It is screwed tightly upon the cup and prevents the escape of oil. This is `an advantage over other cups which have parts oi' the mechanism protruding through the top of the cup for adjustment of the feed. Having thus described our invention, what we claim, and desire to secure by Letters Patent isl The combination of an oil-cup with an independent central stem passing through the oil-cup and whereby it is secured to the machine to be lubricated, having a hole through its center, within which is a vibrating valve for controlling the flow of oil to the bearing, an adjustable cap consisting of a cylindrical portion which is screwed upon the top of the central stem, and a yoke passing from one side to the other across the top of the valvesteln, whereby the throw of said stem is limited.

2. The combination of an oil-cup with an independent central stem passing through the oil-cup and whereby it is secured to the machine to be lubricated, having a hole through its center, within which is a vibrating valve for controlling `the flow of oil to the bearing, an adjustable cap consisting of a cylindrical portion which is split at one point, so as to be tightened or expanded by pressure, and a yoke passing across the top from side to side, the under side of the interior of which is in proximity to the top of the valve-stem,where by the throw of the valve-stem is limited.
