NON-EXPLOSIVE OIL-CAN.

SPECIFICATION forming part of Letters B'atent No. 644,831, dated March 6, 1900.

Application filed August 3, 1899. Serial No. 725,967. (No model.)

To all whom it may concern.-

Be it known that we, ELIZABETH SHADE and HARRY SHADE, citizens of' the United States of America,residin g at Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Non-Explosive Oil-Cans, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in oil-cans, and more particularly to that class known as non-explosive oil-cans.

The invention has for one object to provide novel means whereby the flame may be prevented entering the interior of the can, thereby obviating an explosion that would otherwise take place.

The invention has for its further object to construct an oil-can of this class that will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture.

The invention still further aims to construct an oil-can the outlet of which will be closed when the can is in its normal position.

With the aboveand other objects in view the invention finally consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail, refer once is had to the acoompanyingdrawings, forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the. several views, and in which- Figure 1 is a side elevation of a can, partly in vertical section, showing our improvement attached thereto. Fig. 2 is a top plan view of the same with the bail partly broken away. Fig. 3 is a perspective view of the gravity lever and valve attached thereto. Fig. 4 is a longitudinal sectional view taken on the line 4: 4 of Fig. 1

Referring to the drawings by reference-numerals, 1 represents the body of the oil-can. 2 represents the handle, rigidly secured thereto, and 3 the bail, which is of the ordinary and well-known construction,

4 represents the oil-inlet, said inlet being provided with a screw-threaded cap 5.

A hood 6 is arranged on the top of the can, and an outlet-spout 7 extends into the said hood. An outlet 8 is arranged in the top of the can, said outlet having an upwardly-extending pipe 9, which extends to a point in close proximity with the top of the hood 6. The said outlet is also provided with a gravityvalve 10, connected by means of a valve-stem 10 to a gravity-lever 11, which is pivotally secured at 12 to a lug 13, the latter being se cured to the under face of the top of the can. A trap 1-1 is formed-between the inner walls of the hood 6 and the outer walls of the pipe 9.

The operation of our improved oil-can is as follows: When the can is tilted to the required angle, the gravity-lever will operate the valve, releasing the same from its seat and allowing the oil to pass through the opening 8 and pipe 9 into the trap and thence through the outlet-spout 7 thereby filling the trap 14, as shown in Fig. l of the drawings.

In order to check the flame from entering the interior of the can, two safeguards are provided: first, the flame may be arrested by reason of the oil gathered in the trap 14:, and, further, by means of the gravity or check valve 10 closing the opening 8 leading into the body of the can from the pipe 9.

It will be readily understood from the foregoing description that an explosion of the can with our improvements attached thereto will be practically impossible, as such explosions are usually caused by reason of the flame entering the body of the can and igniting with the gas formed therein.

Particular attention is directed to the fact that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having thus fully described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, the combination with the can-body and the semi-oval-shaped hood mounted on the top thereof and forming a trap, of an outlet-spout secured in said hood and communicating with the interior thereof, a pipe arranged in a verti cal position within said hood and communicatoutlet of a semi-oval-shaped hood inclosing the said outlet and suitably connected to the top of the can-body, an outlet-spout secured in the wall of said hood with its inner end in close proximity to the top of the can, and a horizontally-extending gravity-lever having "its one end pivotally connected to the under face of the can-top and a valve secured near the other end of said lever for closing the oiloutlet from the can to the hood, substantially as set forth.

3. The combination with the body portion, of an oil-can provided with a flat top, having an oil-inlet and an oil-outlet, of a semi-ovalshaped hood on top of the can and inclosing the oil-outlet and forming a trap, a pipe mounted on top of the can within the hood and communicating with the oil-outlet, an outlet-spout secured in the Wall of the hood, a pivotally -supported gravity-lever, and a ball-valve carried by said gravity-lever and adapted to close the oil-outlet from the can to the hood when the can is in an upright position, substantially as set forth.

at. The combination with a can-body having a flat top provided with an outlet, of a semioval-shaped hood mounted on the top and inolosing said outlet and forming a trap, and a pivotally-supported gravity-lever carrying a valve adapted to normally close the said outlet, substantially as set forth.

5. In an oil-can, the combination with the can proper having a flat top provided with an outlet and a trap surrounding said outlet, of a gravity-lever pivotally supported at its one end from the under side of said flat top, and

a ball-valve secured to said lever and adapted to normally close said outlet, substantially as set forth.

6. In an oil-can, the combination with the body portion thereof having a flat top and an outlet arranged therein, of a vertical tube secured to the said top and surrounding said opening, a semi-oval-shaped hood of greater height than the said tube adapted to be socured to the said top and inclose the said tube,.said hood forming a trap, a dischargesp'out secured to the said hood, extending therein to close proximity to the said top, a valve adapted to close the said opening, a valve-stem secured to the said valve, and a gravity-lever suitably arranged within the said can-body and connected to the said valvestem, substantially as described.

7. In an oil-can, the combination with the body portion thereof having a flat top and an outlet arranged therein, of a vertical tube secured to the said top and surrounding said opening, a semi-oval-shaped hood of greater height than the said tube adapted to be secured to the said top and inclose the said tube, said hood forming a trap, a dischargespout secured to the said hood extending therein to close proximity to the said top, a valve adapted to close the said opening, a valve-stem secured to the said valve, a lug suitably secured to the inner face of said top, a gravity-lever pivotally connected at one end to the said lug and suitably connected at its opposite end to the said valve-stem, and a suitable inlet arranged in the said top, substantially as described.

In testimony whereof we affix our signatures in the presence or" two Witnesses.
