N0. 391,336. Patented Oct. 16, 1888.

SPECIFICATION forming part of Letters Patent No. 391,336, dated October 16, 1888.

(No model.)

To all whom it may concern:

Be it known that I, IVIARK Portrait, of Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a vertical sectional elevation showing the air-compressor within the body of the can. Fig. 2 is a like view showing the air-compressor in the handle.

My invention relates to oil-cups which are semi-automatic in their action-that is to say, in which a flow of oil is obtained from the discharge-pipe even when the can or cup is in a vertical position by the opening of a gate or valve by a lever or equivalent mechanism; and it further relates to that class in which an airpressure is maintained upon the surface of the oil, and by which pressure the oil is ejected from the can and out through the dischargeipe. D My object is to provide an improved oil can simple in construction, efficient in operation, and either portable or stationary.

My invention consists in the several novel features of construction and operation,hereinafter described, and which are specifically set forth in the clauses of claims hereunto annexed.

It is constructed as follows: A is the body of the oil-cup, and 1 is the handle affixed to one side thereof and provided with an upward arm, 2.

In Fig. l I show the air-compressor 3, removably inserted into the top of the can, and the opening receiving this compressor is also the opening through which the oil is fed into the can.

B is the dischargepipe, the lower portion of which consists of the tube 4, secured in the top of the can and provided with a conical perforated valve-seat, 5, of rubber or other material, on its upper end, in which is a central opening, 6.

7 is the feed-pipe, extending from the bottom of the can upward into the bottom of the tube4, and Sis a packing of filtering material, with which the tube 4 is filled, and through which the oil is filtered and strained.

The duct .1; through the valve-seat 5 opens downward into the filtering-chamber and its packing 8, and the oil passes from this chamber,when the valve is open,into the valve-seat and through the valve into the discharge-opening in tube 9.

The upper part of discharge-tube Bconsists of a tube, 9, fitting over the exterior of the tube at and adapted to slide vertically thereon. Upon the upper end ofthis tube 9 is a head, 10,. which receives the discharge-pipe 11.

12 is a conical valve in the tube 9.

13 is the port opening into the lower end of the discharge-pipe 11.

Upon the exterior of the tube 9, adjacent to its lower end, is the female part of the coupling 14, in which one end of the lever 15 is coupled. This lever is pivotally mounted in the upper end of the standard 2 and projects outward and downward,so as to form a thumbpiece, 16.

17 is a thumb-screw inserted through the lever and bearing against the standard 2 to regu late the throw of the lever and the consequent vertical sliding of the tube 9 upon the tube 4 and the resultant opening of the valve in the discharge-pipe, and 18 is a spring connected at one end to the handle and at the other to the lever l5,whieh spring operates to draw the tube 9 downward and close the valve whenever it is opened by the pressure upon the lever thumb-piece.

In Fig. 2 I show a removable cap, 19, upon the top of the oil-can, closing the filling-hole, and I also show a part of the handle of tubular form, in the vertical portion of which is the air-compressor 3, and the lower part of which consists of the induction pipe 20, through which the air is forced from the pump into the can.

The operation is as follows: Having filled the can with oil partially full, a few strokes upon the air-compressor will create an airpressure upon the surface of the oil of sufficient strength that when the valve in the discharge-pipe is opened by the downward pressure ofthe thumb or finger upon the thumb-piece 16 of the lever 15 the oil will be forced out from the can through the feed-pipe7 into the tube4, through the filter 8, and out through the valve into and through a discharge pipe or nozzle, 11. This outward discharge w1ll be continuous so long as the valve is kept open and the requisite air-pressure is maintained; or the discharge may be in drops through the quick operation of the lever 15. The spring 18 operates to close the valve whenever the thumb- I piece is released from pressure. W'henever the air-pressure is reduced, it is readily restored by a few strokes upon the air-compressor.

What I claim as my invention, and desire to secure by Letters Patent, is

1. An oil-can consisting ofa body, A, provided with an air-compressor, 3, a handle, 1, a dischargetube consisting of the seetionset and 9, one sliding over the other, a perforated valve-seat at the upper end of the tube 4,21 valve Within the tube 9,and a lever, 16,n1ounted upon the handle and connected to the tube9 and provided with a return-spring, substantiall y as described.

2. An oil-can consisting of a body, A, aireompressor 3, adischarge-pipe composed of a tube,4,secu red to the can,atube,9,sliding over the tube 4,a perforated valve-seat at the upper end of the tube 4,and a conical valve within the tube 9, raised or lowered by the vertical movernent of the tube 9.

In Witness whereof I have hereunto set my hand this 5th day of April. 1888.
