UNITED STATES PATENT DFFICE ALBERT c. GRUNWALD, or CHICAGO, ILLINOIS, ASSIGNOR r0 PR EOISION METAL WORKERS, A CORPORATION OF ILLINOIS.

OIL-CUP.

Application filed October 8, 1920.

To all whom it may concern Be it known that I, ALBERT C. GRUnwALn, a citizen of the United States, residlng at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Oil-Cups, of which the following is a specification.

This invention relates partlcularly to 011 cups adapted to be applied to bearings where it is not convenient to employ forced feed.

The primary objectis to provide an improved oil cup which may be readily refilled, and which is adapted to effectively exclude dust and grit.

The invention is illustrated in its preferred embodiment in the accompanying drawing, in which Figure 1 represents an elevational v ew of the improved oil cup; Fig. 2, a plan yiew of the same, in a closed condition; Fig g3, a plan view of the same in open condition; Fig. 4: an inner view of the cap employed; and Fig. 5 is a detail section of the cover and upper part of the oil cup.

In the construction illustrated A represents a cup or elongated tubular member, which is provided at one end with a threaded nipple A and which is equlpped at the opposite end with a cap A The tubular body A and nipple A} are preferably formed integrally by drawing a steel disk into cup form, the bottom port on of the cup being contacted to form the nipple and perforated to provide a passage through which oil may pass to the bearing. In the illustration given, the cup is equipped at this lower portion with a wick B, which extends through the tubular nipple A The cap A is preferably stamped from a disk of sheet metal. It has the upwardly dished or semispherical top portion 1 and the depending flange 1 The cap is provided at its apex with a central perforation 2, and at some distance therefrom with an elongated perforation or slot 3. The metal of the cap is struck outwardly at points 4;, thus providing stops. Mounted on the cap is a segmental closure 5, which is curved to correspond with the curvature of the cap. The member 5 is preferably formed from sheet metal. It is provided at its apex with a perforated pivotal portion 5*, and is provided at its periphery with a down-turned flange 5", which embraces the flange 1 the Specification of Letters Patent.

lower edge portion of the flange 5 being spun inwardly beneath the edge of the flange i as indicated at 5. The segmental closure 5 is connected with the cap at its apex by a rivet 6, which serves as a pivot the rivet der flexure, thus holding the closure tight against the top surface of the cap. At the extremities of the flange 5 the metal is extended and curved into cylindrical form, to provide finger pieces 8, by means of which the closure may be swung about the vertical pivot 6. The segmental closure 5 presents sharp radial edges 9, adapted to scrape the outer surface of the cap A clean throughout the arc of movement. Such a close fit is secured by the construction employed as to effectively exclude all dust and grit from the oil cup.

The improved oil cup is adapted for use in connectionwith the bearings of stationary engines, in connection with the bearings for springs of automobiles, and in various other situations. The improved device is exceedingly simple in construction, capable of being manufactured at small cost and thoroughly effective for its purpose. The cup may be of convenient size to properly lubricate an ordinary bearing for a period of several weeks, without the necessity of refilling the cup in the meantime.

In the manufacture of the device, the cap and the closure applied thereto, may be assembled before applying the cap to cup A. The cap may then be forced onto the cup with a close fit, which will effectively secure it in position.

What I regard as new and cure by Letters Patent, is:

1. A device of the character set forth, comprising an oil cup equipped at one end with a cap having a bowed top wall and a depending flange embracing the cup, said top wall being provided at some distance from the center with a perforation through which oil may be introduced, and a segmental closure surmounting said cap and swivelly connected therewith by a central vertical pivot, and a leaf spring engaging the inner surface of the top wall of the cap, said spring being engaged by the inner end of said pivot and held under flexure thereby.

2. A device of the character set forth; comprising an oil cup equipped at one end 7 with a cap comprising a bowed top wall and. a depending flange which embraces the up-' per portion of said cup, said top wall being provided with a perforation through which oil may be introduced and having a depend ing flange with an inturned lower edge engagingthe lower edge of the flange of said cap, theflange of said closure being pro- 10 vided with a finger piece, ,a leaf spring bearing against the inner surface of said cap, and an axial pivot connecting said closure to the central portion of saidcap and to said sprin for the purposeset forth. 15
