To all/whom# may concern.'

Be itknown that I, HANS LIEN, a citizen of the United States, residing at Brock; ton, in the county of Roosevelt and State ofMontana, have invented certain new and useful Improvements in Oil-Cansgiand I do hereby declare the following to be a f ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved oil can; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and dened in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Figure 1 is a view of the improved oil can in central vertical section, with some parts broken away; and

Fig. 2 is a fragmentary bottom plan view.

The body 3 of the oil can, with the excepvtion of its bottom, is spun or otherwise formed from sheet metal and the disk-likel bottom 4 thereof, which is removable, has screw threaded engagement with a relatively wide cast rim 5. In the upper face of the rim 5, at the outer edge thereof, is an annular groove 6, into which extends the lower edge of the body 3 which is soldered or otherwise secured thereto. Formed with the rim 5, is an inturned flange 7 having on its under face a gasket 8, against which the bottom 4 impinges to afford an oil tight joint. Integrally formed with the under face of the bottom 4 is a finger hold 9, inthe form of a rib, by which said bottom may be screwed into the rim 5 or unscrewed therefrom. While the drawings show the bottom 4 and rim 5 to be of cast metal, they of course may be pressed from sheet metal, or otherwise formed.

In the contracted top of the body 3 is a filling opening 10 normally closed by a screw cap 11. Axially located in the body 3 is a cylindrical pump chamber 12, the upper end of which is closed by a cast head 13, which extends through the top of said body, is rigidly secured thereto, and supports the lower end of said chamber above the bottom 4. The lower end of the pump chamber 12 is closed by a flanged head 14 which ts within said chamber `and is soldered or otherwise secured thereto.

A curved spout 15 is detachably secured to the body of the oil can by a collar 16 hav-l ing screw threaded engagement with .the headV 13. This collar 16 has an inturned flange 17 which overlaps a flange 18 on the spout 15 and a gasket 19 is interposed between the head 13 and flange 18. By screwing the collar 16 onto the head 13, its flange 17 acting on the flange 18, detachably connects the spout 15 to the body 3 and coinpresses the gasket 19 between the head 13 and flange 18 to form an oil tight joint between the spout and can.

The pump chamber 12 has an oblique pump cylinder 20 which extends through the wall of the body 3 and its outer end is closed by a screw cap 2 1. A piston 22 is mounted in the'pump cylinder 2O and is yieldingly lifted into. its uppermost position by a coiled spring 23 interposed between said piston and the opposite wall of the pump chamber 12. Secured to the piston 22 is a stem 24 which loosely works through the cap 21 and has, on its outer end, a finger piece 25 by which said piston may be operated. In the lower head 14 of the pump chamber 12 is an intake post 26, normally closed by a check valve 27 and in the upper head 13 of said chamber is an outlet port 28, normally closed by a check valve 29. Each check valve 27 and 29 is provided with a stem 30 which is guided by a bracket 31 on the respective head of the pump chamber. Coiled springs 32, compressed between each check valve 27 and 29 and its respective bracket 31, yieldingly hold said valves closed. Attached to the oil can is a hand piece'33, in convenient relation to the finger piece 25.

The check valve 27 is arranged to be opened to fill the pump chamber 12 with oil from the oil can, under the suction stroke of the piston 22 and remain closed under the compression stroke thereof. The check valve 29 is arranged for reverse action in respect to the check valve 27 and opens under the compression stroke of the piston 22,

Vto permit a discharge of oil from the pump -chamber 12 into the spout 15, under the compression stroke of the piston 22 and said check valve remains closed under the suction stroke thereof.

From the above description it is evident that oil from the improved can is discharged through its spout, under this action of Vthe piston, irrespective of the position of the oil can in respect to the part to be oiled. Access may be had to the oil can through the removable bottom 4 for the inspection of the valve 27 or other parts. By unscrewing the collar 16 from the head 13, access may be had to the valve 29. The `detachable spout l5 can be readily replaced, when worn out or broken, b a newone.

What claim is An oil can having a discharge spout, a cylindrical pump chamber suspended within the oil can from the top thereof, and having an intermediate lateral pump cylinder cX- tending through the oil can, a piston mount` ed in the pump cylinder and having an op` erating stem, a spring compressed between the wall of the pump chamber and the piston, two ports in opposite ends of the pump chamber leading, the one from the oil can to said chamber and the other from said chamber to the discharge spout, a check valve nor- I-IANS LIENv Witnesses OLE H.
