UNITED STATES PATENT i OFFICE.

LEWIS A. HARKER, OF COLUMBUS, OHIO, ASSIGNOR OF TWO-THIRDS TO CHARLES H. AMANII AND WILLIAM EWING, OF SAME PLACE.

OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 255,109, dated March 21, 1882.

Application filed February 1, 1.882. (No model.)

To all 'whom fit may concern Be it known that I, Lewis A. HARKER, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare the following to be a full, clear, and exact description of the' invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in oil-cans, the object being to provide an oil-can with improved construction and arrangement of devices for opening and closing the oil-discharge passage and the ventopening ot the can. i

With these ends in view my invention consists in certain details ot' construction and combinations of parts, as will hereinafter be described, and pointed out in the claims..

In the accompanying drawings, Figure l is a view in perspective of an oil-can provided with my improvement. Fig. 2 is a vertical section of the same, and Fig. 3 is a detailed view ofthe thumb-lever and dcvicesconnected therewith.

A representsan oil-can, which may be ofany desired size, form, or construction.

' B is the lling-aperture, and B the screwcap covering 'the same.

C is a handle, attached to the bail C', the ends of the latter being journaled in the bailears a a', attached to the top ofthe can.

D is the oil-discharge nozzle or spout, and

is constructed with an enlarged portion, D,

which is secured over the oil-discharge opening E in the top of the can. The dischargeopeningE is of less diameter than that of the portion D ot' the spout, in order to form a valve-seat, F, within such enlargement D',

4o which in fact constitutes a valvechamber. That the valve-seat may not become bent or twisted so as to prevent the valve finding a tight seat thereon, thcspout I) is provided with a brace, G, which serves to stiien and strengthen the spout, and by preventing it from becoming bent or` twisted out of shape while a transita or in use thereby operates to preserve the form of the valve-seat.

To the under side ofthe top of the can is at- 5o tached a bracket, H, to which is pivoted the lever I, which latter is preferably made angle 'shape in cross-section, so that light and comparatively inexpensive material may be employed and still insure proper stiffness and rigidity in the lever for the purposes in view. One end of the lever I has the wire b soldered or otherwise fastened thereto, said wire being upwardly bent, as at c, and provided with a hook, d, which is inserted through the en.

larged opening c in the valve-stem fof the valve g. The valve g may be made of leather or other equivalent material, and consists of a hat disk, which snugly tits upon the valve-seat F. In order that the valve may always accommodate itself to its seat, and thus insure a perfectly tight joint and prevent any leakage or escape of oil, the stem is connected to the lever by the universal joint described, which allows the'valve to be self-adjustable'and fit tightly against its seat. K is a `vent-opening in the top of the can, through which is inserted the stem L, `the lower end thereof extending through the bottom h of the guide-bracket t', while the upper end of the stem is provided with a disk or stop, j.

To the valve-stem Lis secured the vent-valve K by means of the disk or equivalent device rigidly fastened to the stem, whereby the ventvalve is retained against displacement and caused to seat against the under side of the can-top and over the vent-opening.

M is a spiral spring encircling the lower portion ofthe valve-stein L, the lower end of the springresting on the bottom of the bracket z', and the upper end resting against the horizontal portion m of the lever l. The spring is held in proper position by means of the depending portion m ot' the lever engaging one side of the spring and the side m2 ot' the bracket. This spring serves to force upwardly one endof the lever I and depress its opposite end, thereby keeping the oil-valve snugly against its seat. Aspiral spring, N, encircles the upper portion ot' the valve-stem L, thelower end ot' the spring restingl upon the top of the can and its upper end resting against the under side ofthe disk or button j, and by its eX- pansive force serves to retain the vent-valve closed against its seat. O is a thumb-lever,

constructed with downwardly-projecting ears or sides, o, through which it is pivoted to the standard P by pivot p.' The top portion, p',

IOO

of the lever strikes against the upper end of the standard P, and thereby limits the movement ofthe lever. By depressing the thumblever both spiral springs are compressed and both the vent-valve and the oil-valve are opened, the vent-vale opening downwardly, admitting air to the interior of' the can, and the oil-valve opening upwardly, allowing the oil to be discharged from the can. Vhen pressure is removed from the thumb-lever the spiral springs serve to close both valves.

The construction and arrangement ofparts is simple and durable, and the improvement may be produced at a comparatively small cost.

It is evident that many slight changes in the construction and relative arrangement of parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not restrict myself to the particular construction and ar-4 rangement ofparts shown and described; but,

Having fully describedmy invention, what I claim as new and desire to secure by Letters Extent, is-

1. In an oil-can, the combination, with the discharge-spout constructed with an enlarged portion, D', at its lower end, said enlarged portion being secured to the top of the can over the oil-discharge opening formed therein, whereby the top of the can serves as a valveseat, of a downwardly-closin g valve loosely arranged within said enlarged portion of the spout or nozzle, and suitable levers for actuating the valve, substantially as set forth.

2. In an oil-can, the combination, with 'the dischargespout constructed with an enlarged portion, D', at tslower end, said enlarged portion being secured to the top of the can over the oildischarge opening formed therein, whereby the top of the can serves as a valve seat, of the down wardly-closing valve loosely arranged within the spout, and levers I and O and connecting devices, the rod b, and universal joint connecting the valve stem and rod, substantially as set forth.

3. In an oil-can, the combination, with the bracket secured to the under side ot' the top of the can and the vent-valve stem working through the lower end of the bracket, of an angle-shaped lever, I, and a spiral spring encircling the valve-stem, one side ot the spring having a bearing on the side of the bracket and the other side ofthe spring having a bearing on the vertical portion of the lever, substantially as set forth'.

l1'. The combination, with the vent-valve and stem, ofthe supporting-bracket, the two spiral springs, and the thumb-lever, substantially as set forth.

5. Thecombination, with thevent--valvestem and spiral spring N, encircling its'upper end, ofthe thumb-lever 0 and standard I), the latter constructed to form a stop and limit the upward movement of said lever, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
