Application filed 1' une 13, 1916. Serial No. 108,531.

To all whom z't may concern.' j

Be it known that I, THEoDoRE Romans, a citizen of the United States, residin at Poplar, in the county of Sheridan and tate of Montana, have invented new and useful Improvements in Gil-Cans, of which the following is a specification.

This invention relates to oil cans of the forced feed type, and one of the objects of the invention is to provide means whereby the oil may be ejected from the can when the said can is sustained either in a vertical position, at an inclination or when the said can is inverted.

1n carrying out my invention I propose to construct an oil can wherein the handle provides the cylinder for the air pump and to arrange within the said can an auxiliary reservoir providing what may be termed a compression chamber receiving the air from the pump and having a port or ports communicating with the interior of the can proper, an outlet tube being arranged within the can and communicating with the 21S chamber, a valve spout being provided for the tube, the valve having a single port and which is normally retained in a closed position by spring pressed means having an operative member disposed in close proximity at to the handle, whereby the same may be easily actuated by the operator and also whereby a certain quantity of the oil will at all times be retained in the compression chamber regardless of the angle at which the can is held, tu so that even when the can is inverted oil may be dispensed therefro It is a further object of the invention to produce a device of this character which shall embody the desirable features of simau plicity, cheapness and thorough eciency.

With the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and fall- 415 in within the scope of the appended claim.

n the drawing:

Figure 1 is a side elevation of an oil can constructed in accordance with the present invention,

Fig. 2 is a central vertical longitudinal sectional view through the same,

Fig. 3 is a horizontal sectional view through the device taken in a plane above the compression chamber.

Fig. 4 is an enlarged detail sectional view approximately on the line 1-41 of Fig. 2,

Fig. 5 is an enlarged sectional view through the valve showing the same in its closed position, and

lig. 6 is a similar view showing the valve in lts open position. A 1n the drawing like reference characters designate corresponding parts throughout the several views, and the numeral 10 designates the can body that has its top provided with a filling opening closed by a removable cap 11,

The handle is indicated b the numeral 12 and comprises a c lindricaiI member within which is arrange a piston operated by a suitable rod 13 that rojects through the upper and open end o the tube 12. rlhe tube, at the upper end thereof, is connected to the can 10 by a bracket 14: and to the lower end of the said can by a pipe member 15 which provides the air inlet port for the can.

Arranged in the can, adjacent the bottom thereof is the compression chamber, indicated by the numeral 16. The com ression chamber includes a top 17 which is isposed angularly with relation to the straight bottom of the can, the said top portion 17 slanting from a suitable distance above the air inlet port 15 toward the opposite side and bottom of the can 10, and the top 17 of the compression chamberis provided with an angular side 18 which is connected with the bottom of the can but which, for the major portion thereof, is spaced away from the sides of the can so as to provide a passage for the oil in the can between the said can and the compression chamber 16. The numeral 19 designates the oilinlet portion which, it will be noted, is disposed below the air inlet portion 15, the pipe providing the said ihlet port communicating with the compression chamber 16. The sides of the compression chamber may be provided wlth one or more restricted apertures in the nature of bleed ports 20, whereby the air com pressed within the chamber 16 may find an exit to within the can 10.

The numeral 21 designates the outlet tube arranged between the compression chamber and top of the can 10, the said tube being disposed preferably diametrically opposite the handle 12, and the end thereof, extendl` ing through the top of the can, is provided with a valve casing 22 in which is arranged a valve 23 having a single port 24, and connected with this valve isa stem 25 which passes transversely over the top of the can ejected through the and has its free end supported by a bracket 26. The end of the rod 25 extending beyond the bracket 26 has arranged thereon a han dle 27 provided with an offset finger 28 that is adapted toxcontact with the stoplug 29 upon the bracket 26 and the numeral 30 designates a l spring which surrounds the stem 25- and has one of its ends secured to the bracket 26 and its opposite end secured to the stem whereb the valve 23 may be normally turned to ring the port 24 thereof transverse of the port in the valve casing and normally close the tube 21. The numeral 31 designates the outlet spout connected with the valve casing 22.

The operation of the device may be briefly described as follows: Suflicient oil will be allowed to pass through the port 19 from the can 10 to the compression chamber 16 and when the piston in the hollow handle is actuated to force a desired amount of air to within the compression chamber oil will be tube 21, port 24 of the valve 23 and through the outlet spout 32, when the operating member 27 is actuated to bring the port 24. into alinement with the ports or bores of the tube of the spout.

vWhen pressure upon the handle 27 is released, the spring 30 will, as stated, turn the valve toits operative position. By constructing the compression chamber w1th an angular top, it will be noted that even when the can is completely reversed, a sufficient quantity of oil will be maintained within the compression chamber to properly lubricate the parts of the machine when the valve is actuated.

From the above description, taken in connection with the accompanying drawing, the simplicity of the device, as well as the advantages thereof will, it is thought, be perectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what l claim is: The herein described forced feed oil can, includin a body having its handle in the nature o an air pump, a compression chamber within the body at the bottom thereof,

said chamber having an upper inclined wall which is round in plan, a flange secured to the periphery of the said wall and connected to the bottom of the receptacle and spaced from the sides of the said receptacle at all points except at thev reduced endof the chamber, said chamber having an entrance opening in a line with the bottom wa'll of the receptacle and having a pipe communication with the pump adjacent thetop of the chamber at the widened end thereof, said chamber, below the said pipe connection having bleed openings, and an outlet spout between the reduced end of the said chamber and the top of the can.

In testimony whereof I ailix my signature.
