' ATO all whom i may Be it known that I, IosP l?EARsO1\T ROG-I ERS, ofy the cityof Toronto,in,the county of; York and Province of Ontario, Canada; have invented a certainf new and yuseful Oil-Canl and Lamp-Filler,.of which-the' following isa specification. .1 f f, I

Theobject of the invention is ,toprovide a` cheap, simple, clean, and effective device for filling lamps and other receptacles withoil by` means of air-pressure andinsuring a steady. flow of oil, which may bereadilyfchecked; so` as to prevent any overflow; and it'consists, e..`

lsentially, of an oil-can provided with an air` pump cylinder,in which is I tteda piston-head withy an air-valve, and means for jadmitting air to the lower part of the air-'pump cylinder below the piston-head, and a hollow'pis'ton-rod having an open upper end, also a flexible airtube, forming acommunic'ation between the interior of the can above the oil and the interior of the hollow piston-rodfabovethe upper surface of the can, the open upper end of, the piston-rod being closed byfthe linger when theI pump is being operated 'and while the oil is flowing-through the ejecting-pipe, the finger being removed when it isfdesired tocheck the fiow, as hereinafter more particularly described, and then definitely pointed outin the claims. l r l Figure l is a perspective view partially in section and broken'` away to expose the interior of the can. Fig. 2 isaperspective detail of the piston-head, the valve, andvalve-seat shown in-Fig. 1. Fig. 3 is a idetail showing the top of the oil-ejecting pipe, itsY mode of connection, the eccentric opening, and the waste-oil chamber. Y

Like letters of referencegf/indicate similar parts in the dierent figures.

In Fig. 1, A is'the bodygot1 the can. ware bosses formed thereon, andb isthe bail or the handle. V n .y l

B is a beveled rim wherebythe top of the can is preferably countersunk.

C is a screw-cap covering the hole through which the oil is poured into the can.

D is an'. oilejectingf pipe .which passes through anorice S, ,which is larger than the diameter of thepipe D, which latter is fitted fintothe upper end of the'oil-ejecting tube D',

the pipe D andejectingetube D forming, when tfitted together, an,oil'-ejecting pipe. (See Figs. .l and 3.

The'oriti'ce; S is eccentric with relation to the pipe' D, and s is a pin for keeping-thepipe in place; T is a waste-oil chamber formed by,` enlarging the top of the eject- `ing-tube D, andwhichis secured to the bottom of the top of thecan.

It isa groove or gutter formed in the top of the can for conveying waste oil through the eccentricorice S to the waste-oil chamber T.

By turning `the bent end of the ejectingpipe D the pin s may come under the wide end of the eccentric orifice S and the pipe D may be withdrawn from the ejecting-tube D', so as to allow the oil in the waste-oil chamber T to flow down ,the ejecting-tube D. f

d is the inlet to the oil-ejecting tube D vand is located near the bottom of the can,

.of the hollow piston-rod H. This stem F is made hollowjso as to admitpf instant relief of air-pressure inltheinterior of the can, so as to check; the new ,cfaoil when thenger is removed from., thej ,hollow piston-rod, as hereinafter vreferred to.,l Thislexible tube F is made suliiciently long to permit of one end Y thereof rising and falling with themotion of the hollow piston-rod H.

G ris an air-pump cylinder which v passes through and is soldered to thetop of the oilcan A. The upper portion above the surface of the can is screw-threaded, and thereon is screwed the cap g, through which the hollow piston-rod passes and is loosely fitted, so as to permit ot' the passage of the air to the interior of the cylinder.

The hollow piston-rod II is provided with a piston-head I and au air-valve L. This hollow pistou-rod is open at h. then the piston-rod is boing forced up and down in order to pump air into the upper part of the can the hole h is closed by the finger, which may be removed when it is desired to allow the compressed air to escape from the interior of the can, as hereinafter described, and thus to stop the iiow of oil.

O is the valve-stem which is tted to the valve L, and which is adapted to move in the airway N.

Fig. 2 shows a detail off the valve and piston-head, in which L is the air-valve, which is adapted to tit down on the seat M when the valve is closed. U is piston-packing, and v is a spring for pressing the packing against the side of the cylinder in the usual manner, and K is a iiangefor holding the packing. In this view, Fig. 2, the Valve is shown open, the face being raised from its seat, as on the downstroke of the piston, the air passing through to the interior of the hollow pistonrod from the bottom of the cylinder.

In Fig. 1 is seen the method by which the air is admitted to the bottom of the cylinder below the piston-head I, in which V is a pipe which communicates with the interior of the pump-cylinder G near its top and with an airchamber W. The top of this chamber is provided with orifices and valve L similar to those in the piston-head I, so that when the piston-head I is being raised the air is drawn through the pipe V to the airchamber vW and, raising the valve L from its seat and passing through the orificesF and the airway of the valve, enters the lower part of the air-chamber. IVhen the piston-head I descends, the valve L becomes closed, the valve L in the piston-head opens, and the air is forced into the interior of the hollow pistonrod, and thence, by means of the hollow stem F', the fiexible tube F, and air-inlet pipe E to the air-space over the oil Q within the can, the finger all this time remaining over the upper orifice h in the hollow piston-rod H, so as to prevent the escape of air. After several strokes of the hollow piston-rod II the air may be sufficiently compressed in the space lettered R to force the oil into the inlet d of the oil-ejecting tube D and into the oil-ejecting pipe D, and which will continue to fiow until the finger moves from the orifice h, when the air, escaping from the interior of the can, relieves the surface of the oil from pressure and thus stops the fiow of the oil.

Instead of having an open orifice at 7L there may be, of course, a small valve supplied,

which can be depressed by the finger when it is desired to permit the escape of the confined air in the can, and thus to check the flow of the oil. A

The air-pump cylinder G instead of being placed within the can may, of course, be attached `to the can outside thereof, when the same eilect will be produced, although itis more convenient to have it as indicated. The oil-ejecting pipe D is also rotatable, as mentioned, for the purpose of withdrawal, as well as to turn the bent spout over the top of the can when the can is not in use.

What I claim as my invention is l. In an' oil can and lamp filler, the combination of the gutter z5; eccentric openingS; oil ejecting pipe D; pin s; waste oil chamber T; and oil ejecting tube D; substantially as described and for the purpose specified.

2. In au oil can and lamp filler, the combination with the can A, of the air pump cylinder G; cap g; hollow piston rod Il; piston head I; air valve L; pipe V; air chamber IV; valve L; hollow stem F; flexible tube F; and air inlet pipe E, substantially as described and for the purpose specified.

3. I-n an oil can and lamp filler, the combination of the can A; air inlet pipe E; flexible tube F; hollow stem F hollow piston rod Il; gnttert; eccentric opening S; pin s; oil ejecting pipe D; waste oil chamber T; oil ejectiug tube D; screw cap C; air pump cylinder G; cap g; piston head I; air valve L; packing U; spring c; flange K; pipe V; air chamber W, and valve L', substantially as described and for the purpose specified.

4. In an oil-can and lamp-filler, the combination of an oil-can, an air-pump cylinder, a hollow piston-rod II communicating with said oil-can and working in said pump-cylinder and having a piston-head I and air-valve L, air-chamber WV and valve L', and a pipe V affording communication between said chamber W and the upper'part of the air-pump cylinder, whereby air is drawn through said pipe V, and by means of the piston-head I and valves L and L is forced through the hollow piston-rod II into the oil-can, substantially as described.

5. In an oil-can and lamp-filler, the combination of an oil can, a pump cylinder and a .hollow piston-rod, a fiexible air-passage between the interior of the can and the interior of said hollow piston-rod,means for pumping air through the piston-rod and flexible air passage so as to compress the air above the oil, and an oil ejectiug pipe, substantially as described and for the purpose specified.

6. In an oil-can and lamp filler, the combination of the can A, fiexible tube F, airpump cylinder G, hollow piston-rod Il, and means for pumping air through the flexible ICO IIO

interior of the can above the oil; and the oil to and open at the other, means for admitting air below the piston-head on the up stroke and a exible tube communicating with the hollow piston-rod and with the interior of the can above the oil, substantially as described.
