OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 432,736, dated July 22, 1890.

Application filed February 13, 189i). Serial No. 340,325. (No model.) i

To all whom it may concern.-

Be it known that I, DUWAYNE E. JOHNSON,

a citizen of the United States, residing at Farlington, in the county of Crawford and State of Kansas, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare that the following is a full,clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oil-cans embodying simple and improved means for forcing the oiltherefrom; and it has for its object to provide an oil-can of this character which will possess advantages in point of inexpensiveness, durability, ease of operation, and general efficiency.

In the drawings, Figure 1 is a perspective view of an oil-can embodying my invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is an enlarged detail sectional view of parts of Fig. 2. Fig. 4 is a horizontal sectional view taken on the line m at, Fig. Fig. 5 is a similar view on the line y y, Fig. 3, looking toward the outer end of spout. Fig. 6 is a similar view on the line z z, 3, looking toward the oil-receptacle. Fig. 7 is a detail perspective view of the valve mechanism removed.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the can, which may be of any suitable or preoil may pass.

ferred construction, and constructed of any desirable material, and is provided with an elongated spout or tube A, having either a curved or straight outlet end a. The can is also provided with an opening a, through which it may be filled, and with a handle a Within the spout of the can is disposed an outer transverse partition B, provided with a series of perforations Z), through which the Below the partition B, betweenthe same and the can proper or receptacle, is disposed a second transverse partition 0, also provided with a series of perforations c, which form ports, the latter partition serving as a valve-seat. A rod D is secured at one end centrally within the partition B, from which it projects downwardly or inwardly through a perforation (I, provided therefor centrally within the partition 0, the purpose of which will be hereinafter set forth.

Upon the valve-seat C, between the same and the partition B, is normally seated a valve E, of smaller diameter than the spout at this point,but of sufficient size to cover the ports in the valve-seat. The valve is normally held to its seat by a coil-spring e, disposed between the partitions B and C and encircling the rod D, the latter passing loosely through the center of the valve.

F design ates a sliding piston disposed below the valve-seat O and fitting closely against the walls of the spout. This sliding piston is provided with a central perforation f, through which the rod D works, and with a series of ports f. Upon the top of the piston F is provided a frame-work G, raised somewhat above the same and serving as a rest for the lower end of a coil-spring H, encircling the rod D and occupying the space between the frame G and the valve-seat C, said spring being of greater tension than the spring 6, and is designed to exert a downward pressure upon the piston. The rod D also passes through the frame and serves to effect an easy movement to the piston F, as well as to retain the coilspring H against displacement.

Upon the piston F, and between the same and the frame G, is disposed a valve I, normally held upon its seat by a coil'spring 'i, encircling the rod D and disposed between the valve and the frame Gr.

For effecting the operation of the valves I provide means which I will now proceed to describe.

J designates a rod, which projects from near the bottom of the can up through the spout to the piston F, to which it is secured, said rod'being bifurcated at its upper secured end to permit of the play of the rod D therebetween. The rod J is pivoted at its lower end to one end of a lever L, the latter being pivoted at about its center to a standard Z, projecting from the bottom of the can. To the free end of the lever is pivoted the lower end of a rod M, which projects upwardly and through a perforation m, provided therefor in the can. The exterior portion of this rod is bent down and over the handle a where it is provided with a thumb-piece m.

The operation and advantages of my invenleased, the spring H returns the piston F to its normal position, during which movement the valve E is held to its seat, while the valve 1 is raised to permit the oil to enter the space between the valves, when the operation may be repeated.

I claim as my invention- 1. The combination, with an oil-can provided witha spout projecting therefrom, of a stationary valve-seat carrying a valve, a sliding piston carrying a valve and working upon a centrally-disposed guide-rod, springs ing the valves and piston to their normal positions, all of said mechanism being contained within the spout, and means for operembracing the latter and adapted for return-- 2. The combination, with an oil-can provided with a spout projecting therefrom, of a stationary valve-seat disposed in said spout and carrying a valve, a centrally-disposed station ary guide-rod proj ectin g inwardly through said valve-seat and valve, a sliding piston working on said rod and within the spout and carrying a valve, an oil-chamber being formed between the valve-seat and piston, and means for operating the piston to eject the oil from said chamber, substantially as set forth.

3. The combination, with an oil-can provided with a spout projecting therefrom, of a stationary valve-seat disposed within the spout and provided with a valve, a stationary partition above the said seat, a sliding piston working in the spout and upon a guide-rod, said piston being provided with a valve and with an arched frame inclosing the latter,

springs for returning the valves and piston to their normal positions, and means for oper-' ating the piston, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
