COVER FOR OiL-oups.

SPECIFICATION forming part of Letters Patent No. 314,638l dated March 3l, 1885.

Application filed December 22, 1884.

To @ZZ whom imag concern:

Be it known that 1, JOHN E. ZIMMERMAN,

a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented a new and useful Improvement in Covers for Oil-Oups, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to covers for Oilcups; te and it has for its object to provide an im- "proved valve for the same which will open to allow the free passage of oil and then automatically close the opening to the cup, and thus prevent the admission of dust, dirt, and

i 5 other foreign matter thereto.

To this end the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying `a perspective view of my improved cover, showing the top of the oil-cup. Fig. 2 is vertical longitudinal section of the saine. Fig. 3 is a detail view of the cover with the 2 5 parts detached. Fig. is a horizontal section on thel line x 00, Fig. 2. Fig. 5 is a perspective view of the cap or cover separated from the cup.

Like letters of reference are used to indicate 3o corresponding parts in the several figures.

Referring to the drawings, A designates the oilcup cap or cover arranged to close the opening in the top of the oil-cup B. This cap or cover A is preferably formed of one piece of metal, and is provided with an annular flange,

C, near its center, which extends outwardly,

as shown, the portion below the fiange being exteriorly threaded at D. Above the flange the cap or cover is formed with a hexagonal face or projection, E, to receive a wrench or similar instrument in screwing it in place to the cup. rIhe cap or @over A is made hollow, its interior walls having vertical ribs or guides F, preferably four in number, which extend from the upper to the lower end, the spaces G between the ribs forming passages for the oil. The closed ends of the cap or cover are each provided with an `opening communicating with a annular ange or projection,

(No model.)

Hin the top being larger in diameter than 5o the opening Iin the bottom.. 5

Jv designates the valve-stem, (shown in detail, Fig. 3,) having its walls concaved, recessed, or hollowed out at K, for the passage ofthe oil, and provided with a valve, L, at its lower end arranged to fit in its seat in the opening I. The sides of the valve are cut away at a to correspond with the recessed walls of the stem, so as to allow the admission of oil from the cup to the cover when the 6o stem is depressed. The upper end of the stem is provided with a disk, M, which may be made detachable, as desired, said disk closing the opening H in the upper end of the cap or cover, and in its normal position fitting flush therewith.

N designates a coiled spring encircling the valve stem, and having one end pressing drawings, Figure 1 is i against the disk M, and the other end against the lower end of the cap or cover around an 7o N', the latter encircling the opening I.

The operation and advantages of my invention will be readily understood froi'nthe foregoing description, taken 'in connection with 75 the annexed drawings. The cup or cover is applied in position, as shown in Figs. 1 and 2, the threaded extension D screwing into the threaded mouth in the top of the oil-cup B, and the flange O resting over the upper edge SO of the latter, a wrench or similar instrument engaging with the hexagonal projection E for the purpose of fitting the cap in place, as stated. A

In operation, by depressing the disk M 8 5 the valve-stem works downward against the pressure of the spring until the valve is withdrawn from its seat to allow the admission of oil to the cap or cover, the oil flowing out through the opening H. V'Vhen pressure is re- 9o lieved, the spring exerts its power and forces the valve-stem to its normal position,the disk closing the opening at the top and fitting ush, as shown, and the valve resting in its seat and closing the opening I at the bottom. 9 5

The ribs or guides F serve to guide the ascent and descent of the valve-stem and hold the spring in place, the spaces between the the interior of the cup,'the opening ribs permitting the free passage of oil through the cap. The flange or projection N at the lower end of cap around the opening I serves to keep the spring in place and prevent dislodgment thereof.

As will be seen, when the valve is pushed away from the opening I, the oil is allowed ingress through the cut-away portion a and the-recessed walls of the valve-stem.

My improved oil-cup cover may be applied to all sizes and forms of oil-cups. It is simple in construction, inexpensive to manufacture, efficient in operation, and convenient in use. By means of the same the oil will be allowed free passage from the cup by the action of the valve, the latter being automatic in operation, so as to close and exclude dust, dirt, and other foreign matter from passing into the cup.

Having described my invention, I claiml. The combination,with the oil-cup provided with a threaded opening, of the cap or cover having a threaded portion to fit thebpening, and a hexagonal face or projection to receive a wrench in turning the cap into place, as set forth. p

2. The combination, with the oil-cup provided with a threaded opening, of the cap or cover 'having a threaded portion to screw into the opening, a hexagonal face or projection to receive a wrench in turning the cap into its place, and an annular flange between the threaded portion and the face or projection, as and for the purpose set forth.

3. The herein-described oil-cup cover having a spring-pressed valve which will open by pressing inward to allow the free passage of oil and then automatically close outward to exclude the admission of foreign matter, as set forth. e

4. An oil-cup cover or cap made hollow and having an opening at the upper and lower ends and avertically-movable automatic valve to open or close said openings, as set forth.

5. An oil-cup cap or cover made hollow and having an opening at the upper and lower ends, ribs or guides extending along the interior walls of the cap, and a vertically-movable valve, arranged and operating as set forth.

6. An oil-cup cover or cap made hollow and having an opening at each end fitting normally iiush with the opening, a valve-stem moving therein, a valve at one end of the stem for closing one of the openings, and a disk at the other end, as set forth.

7. An oil-cup cover or cap made hollow and having an opening at each end, a valve-stem moving therein and having its walls concaved or hollowed out, avalve at one end of the stem having its sides cut away, as described, and a disk at the opposite end, as set forth.

8. An oil-cup cover or cap having an opening at each end, a valve-stem moving therein, a valve at one end of the stem, a disk at the opposite end, and a spring bearing against the disk and the end ofthe cap or cover, as set forth.

9. yAu oil-cup cover or cap made hollow and having an opening at each end, ribs or guides extending along the interior walls of the said cap and forming spaces between each rib, a valve-stem moving in the cap, a valve at one end of the stem, a disk at the other end, and recesses formed in the sides of the valve-stem, the sides of the valve being cut away to correspond with the recesses, as set forth.

10. An oil-cup cover or cap made hollow and having an opening at each end, ribs or guides extending along the interior walls of the said cap, a valve-stem provided with a valve at one end and a disk at the other, a spring bearing against the disk and one end of the cap or cover, and an annular iiange, around which the lower end of the spring lits, as set forth.

1l. An oil-cup cover having asprin'g-pressed valve-stem moving therein and a disk at one end of the stem arranged to close the' eXitopening and to rest ush with the cover in its normal position, as set forth.

In testimony that I claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.

JOHN E. ZIMMERMAN. Witnesses: l

RANDOLPH COLEMAN, WM. HOPE.
