OIL-HOLE COVER OR CAP.

SPECIFICATION forming part of Letters Patent No. 608,243, dated August 2,1898.

` Application nea september 13,1897. semina. 651,506. 11@ mit-.1.a

T a/ZZ whom it nea/y concern:

Be it known that I, FRANK D. WINKLEY, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in-Oil-IIole Covers or Oaps, of

which the following is a specification.

My invention pertains to improvements in oil-hole covers or caps, the construction and advantages of which'will be hereinafter fully set forth, reference being had to the annexed drawings, wherein- Figure 1 is a perspective view of my improved cap in its closed position; Fig. 2, a similar view, the cap being shown open; Figs. 3 and 4, top plan views of Figs. 1 and 2, respectively; Fig. 5, a longitudinal sectional view of the cap in -its closed position; Fig. 6, a similar view, the cap being open; and Fig. 7, a sectional perspectivelview.

The object of my invention is to provide a simple and eflicientcap or cover which may be readily applied to oil-holes of machinery and at the same time one which will be easy of manipulation and thoroughly dust-proof.

Referring to the drawings, A` designates a hollow stern or post formed with a cylindrical recess B, extendingY from the lower end thereof up to the upper end or top C. Said top is provided with an opening D at one side of the center,which communicates with the internal bore B. A cylindrical stud E extends the upper part of the recess, as shown. These' openings are designed to receive a spring H,

formed of a single piece of spring-wire, the' ends being bent around a slight distance from the stem and downwardly, as indicated in Fig. 7.

The lower part of the stem Yis reduced, as

at I, and also provided with a" threaded sec-v tion .I and polygonal section K, the device being designed to be either driven or screwed into place.

L indicates the cover, formed with an opening M of a diameter slightly greater than that of stud E, so that the stud may enter the same when the parts are in their closed position.

An annular groove N is formed in the inner face of the dependingskirt of cover L, the arms of spring II entering said groove when the parts are assembled and tending to draw the cover down upon the top O. The arms of the spring being diametrically opposite exert an equal pressure upon both sides of the cap, preventingany binding action, and, on account of their downward inclination, permitting the cover to be raised a distance equal to-the distance between the bottom of groove N and the top of groove F, less the thickness of the spring, between which points the springarms would be clamped were the cover raised to its extreme height.

The cover may be readily forced into position by exerting a downward pressure thereon and at the same time turning it slightly in the direction in which the arms extend, thus forcing the arms back into groove F, allowing the cover to descend, the spring-arms entering groove N immediately it comes opposite them.

Assuming the cover to be closed, or in the position shown in Figs. l, 3, and 5, wherein the stud E is within opening M, and it be desired .to inject or pour oil into the oil-hole, the operator takes hold of cap L, raises it free from stud E, and turns it around in either direction until openings D and M are in line.

Stud E meanwhile bears upon the under face of the cap and holds said cap in its elevated? movement of the machinery to which it may be attached.

I-Iaving thus described my invention, what I claim is- 1. In an oil-hole cover'or cap, the combination of a hollow stem or post provided with an opening in its upper end; a stud upon the upper end of the post; and a cap rotatably IOO mounted upon the upper end of the post and provided with an opening, said eap being eapablo of rotation so as to bring its opening into alinement with the stud or with the opening formed in the post.

2. In an oil-hole cover or cap, the combination of a hollow stem or post provided with an opening in its upper end, and an oppositely-disposed stud rising therefrom; a cap mounted on said post and provided with an opening to one side of its center, said eap being rotatable whereby its opening may be brought into alinement with the opening in the post or with the stud thereon; and means for drawing said cap down upon the post when the stud and opening in the cap are in alinement.

In an oil-hole cover or eap, the combination of a hollow stem or post provided with an opening at its upper end, and an upwardlyextending eceentrie stud; a cap fitting over the upper end of the post also provided with an opening said opening being to one side of the eenterof the cap; and means for holding the Cap upon said stein allowing longitudinal and rotary motion thereof relative to the post.

4f. In an oil-hole cover or cap, the combination of a hollow post or stem provided with an opening at its upper end to one side of its center; a stud extending upwardly from said upper end at a point approximatelyv opposite said opening; and a cap formed with an opening to one side of its center,rotatably mounted upon said post, said eap also being capable of endwise movement, the stud upon the post being designed to enter the opening in the cap when said opening and the openin g in the post are out of alinement.

5. In an oil-hole cover or cap, the combination of a hollow stem or post provided with an upwardly-extending stud, and with an openin gin its upper end; there being a groove F formed around the post below the opening; a spring II; and a cap designed to be fitted over the upper end of the post, said cap havin g formed therein an annulargroove or channel N designed when the parts are assembled to receive the ends of the spring and to permit a rotary and endwise movement of the cap, substantially as shown and described.

G. In an oil-hole cover or cap, the combination of a hollow stem or post provided with an opening at its upper end and with an upwardly-extending stud; a channel F formed around said post below the opening; dialnetrieally opposite openings G; a spring ll mounted in said openings the free ends of whieh'extend downwardly and around said post; and a cap designed to fit over the upper end of the post, said cap having an internal annular groove N formed therein designed to receive the ends of the spring whereby a longitudinal and rotary motion may be given to the cap.

7. In an oil-hole cover or cap, the combination of a hollow stem or post provided with an opening at its upper end to one side ofthe center thereof and an upwardly-extending stud E; a groove or channel F formed around the post at a point immediately below the top; a spring II the free ends of which extend downwardly and around the post; and a cap designed to lit over the upper end oi the post, said cap being provided with an opening M and an internal channel or groove N to receive the free ends of the spring, substantially as and for the purpose set forth.

S. In an oil-hole cover or eap, the combination of a hollow stem or post provided with an opening at its upper end and with an upwardlyextending stud; oppositely-disposed spring-arms extending around said post below the opening; a eap designed to lit over the upper end of the post, said cap being provided with an internal annular groove designed to receive the spring-arms, substantially as and for the purpose set forth g and an opening formed in the upper faee of the cap.

In witness whereof I hereunto set my hand in the presence of two witnesses.
