OIL CAN.

Application filed June 15,

The invention relates to improvements in oil cans and particularly to an oil can equipped with a pumping attachment and an object of the invention is to provide an attachment which can be attached as aunit to the can'body and can readily be removed for inspection or repair purposes.

A further object oi the invention is to provide a pump which will pump oil with the can body in any position between the upright and, approximately a horizontal one.

A further object of the invention is to provide a pump which will not require priming and which has the valves thereof entirely.

free of springs when working and which draws oil and. discharges oilon the same pump stroke. l

A further object is to provide an 011 can and pump which will not leak.

A further object of the invention is to provide a pump embodying a piston and arranged such that there is oil at all tunes on both sides oi? the'piston, thereby assuring a well lubricated piston.

lVith the above more important objects in view, the invention consists essentially in the arrangement and construction of parts here inatter more particularly described, reference being had to the accompanying draw. ing, in which Fig. 1 is a side view of the complete oil can. r r

sectional view at 55' In the drawing like characters of refer ence indicate corresponding parts in the several figures.

The can body 1 is the ordinary type be ingprovided with a removable filling plug 2, an interiorly screw threaded neck 3 and a handle 4, the handle being shaped to provide a convenient finger grip.

The pump cylinder 5 is oi a predetermined length and has the upper end thereof screw threaded as indicated. at 6 and it is provided therebelow with a stationary collar 7. The cylinder carries the discharge spout 8 which tapers towards its upper end and has the upper end thereof curved as shown. It will,

be observed that the lower end of the spout attached to the cylinder in a location above the collar and that it is offset to clear a 010- W sure rap 9 screw threading ontothe upper end oil thecylinder. A coupling nut 10 is rotatably mounted. on the cylinder above the collar and is exteriorly screw threaded to enter the neck.

The lower end of the cylinder is contit-acted to provide a seat 11 for a ball valve 12 and the valve is prevented from rising further than desired in any suitable manner, such as by indenting the sides of the cylinder above the valve as indicated at 13. To the lower end of the seat, I secure an inclined tube 14: which is adapted when the parts are placed within the can body to take a position inone oi the lower corners ofthe can.

A piston rod 15 is provided and this has thelower end thereof secured to a cross bar 16 permanently attachedto the upper end of a hollow cylindrical head 17, it being observed that oil can flow through the openings 18 and 19 appearing at the sides of the cross bar. The lower-end of the head is interiorly screw threaded to receive the upper end of a screw threaded sleeve 20, the sleeve being providedwith an interior valve seat 21 and with an exterior piston 22 in the form of. an. annular disc permanently fastened to the sleeve. A ball valve 23 is housed within the headiand normally. engages the latter seat and a leather washer 24 forming a gasket is caught between the piston and the lower end of the head.

The upperend of the plunger rod is contracted to provide a stud 25 which passes through the cap aforesaid and within the cap I locate a metal disc 26 and, between the disc and the top of thecap I insert a leather 'washer 27. A bail bar 28 straddles the cap and is mounted on the stud and is held in place by a small washer 29 and the riveted head of the stud. A disc or stop 30 is secured to the piston rod and a coiled compression spring 31 is inserted on the rod between thelatter disc and the disc 26.

The upper end of the cylinder carries a lug 32 at the side remote from the spout and this lug is provided with a pivot pin 33 which attaches the inner forked end of a thumb lever 34 to the lug. The forked ends of the thumb lever are connected pivotally by pins 35 to the downwardly extending ends of the bail bar. The outer end of the thumb lever is provided with a' convenient thumb piece v 36 and the thumb lever overlies the upper to that the-spout finally takes a posit-ion at the opposite side'of the ody from the handle at which time the thumb lever is directly overlyingth handle and is in an up position, being held up by the down pressure of the spring. which is at this time in compression and is actually holding the lower end of the sleeve tightly against the ball valve 12 and holding such valve tightly seated.

' When itis desired to discharge oil from '20 ,the pump, one only rcqu'ires to press down the outer end; of the thumb lever and obviously the oil previously admitted into the upper end of the cylinder past the valve 23 will be discharged by the piston through 25. the spout. At this time also, the suction of the piston causes oil to pass into the lower end ofthe cylinder past the ball valve 12.

[Here it is to be noted that at this time the lower valve is entirely free of the action of the spring which is being compressed by the up movement of the plunger.- Upon the release of the thumb lever, the spring acts to force down. the plunger, the lower valve 12 seating and the upper-valve 23 opening to 15 permit theoil to pass into the upper end of the cylinder.

The pressure of the spring isutilized'also to hold the'washer in the cap tightly pressed against the plunger rod so that there is no leakage at this point and it also operates to hold thesleeve firmly seated on the ball valve 12 when the pump is not in use, with the result that this-pump never re' 'uires priming.

'Theupper part of the han le is designed to limit the down movement of the outer end of the thumb lever so that the piston rod and hail bar cannot become locked man up position.- I might also. point out that when the device is in use the valves are entirely free of e piston is always well lubricated as when the pump is wor ing there is oil on both sides of it.

' What I claim as my invention is 1. The combination with a can body provided with a handle, of a cylinder passing downwardly into the can body and extending beyond the top of the can, a discharge spout carried by the upper end of the cylinder, a lower downwardly seating normally closed ball valve in the lower end of the cylinder, a cap. closing the upper end of the cylinder, a piston rod extending slidably through the cap and into the cylinder, a hollow head secured to the lower end of the rod, a sleeve extending downwardly from the head and providing an internal valve seat therein, a piston carried by the sleeve and operating slidably in the cylinder, :1 stop member suredto the rod, a compression spring mounted on the rod and interposed between the ca and the stop member, said spring normally holding the lower end of the sleeve s rin s or other pressure devices and that t seated on the valve, 0, ball valve housed within the head and normally engaging the internal seat thereof, a bail bar straddling the cap and attached to the upper end of the piston rod and a forked thumb lever pivotally secured to the upper end of the cylinder and overlyingthe handle and having the forked ends thereof pivotally attached to the ends of the bail bar.

2. The combination with a cylinder and a cap on the upper end of the cylinder, of a piston rod extending through the cap, a hail bar connected to the upper cnd of the rod and straddling the cap, rod lifting means pivotally connected to the cylinder and the bail bar, a Washer within the cap, a disc underlying the washer, a stop secured to the piston rod and a compressitm spring encircling the iston rod between the disc and the stop antFcontinuously pressing the disc against the washer.

Signed at Winnipeg this 14th day of May, 1926.
