OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 236,324, dated January 4, 1881. Application filed November 11, 1880. (No model.)

T 0 all whom it may concern:

Be it known that I, SAMUEL GREER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in. Oil-Stoves; and I do hereby declare the following to be a full, 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, reference being had to the accompanying drawing, andlt'o letters or figures of reference marked thereon, which forms a part of this specification. Y

Myinvention relates to an improvement in oil-stoves; and it consists in an introduction and arrangment of parts to keep the oil cool in the reservoir and oil-cups, and to prevent air from entering therein. y

it consists, also, in casting the oil cup or cups and reservoir in one piece, wherebyleakage is avoided and asubstantial support formed that holds these parts firmly together, as will be fully described hereinafter.

The accompanying drawing represents a vertical section of my invention.

, The reservoir A occupies the central portion of the casting, extending from one side to the other, is circular at its ends, and narrowing between them. The top of the reservoir is on a level with the elevations f on top of the oil-cups B, which cups are connected with the reservoir by an enlarged portion, 6, of the casting. The top of the reservoir is fastened to the body by screws, and provided with an opening through which the oil is in troduced.

From the bottom of the reservoir A, through the enlarged portion 6 of the casting, holes forming tubes 0 are drilled in an oblique downward direction, passing into the cups B near the bottom of their vertical sides, and through these tubes the oil is supplied from the res- The tubes 0, being at the bottom of the reservoir, are kept filled as long as any oil remains in the reservoir, thereby precluding air from entering into the cups B.

Gold oil being continuously supplied from the reservoir, the temperature of the oil in the cups is but little varied by the ascending heat of the burners.

On top of the oil-cups B, and cast with them, are elevations f, reaching to a height equal with the top of the reservoir, and on them are soldered the brass burners g. The bottoms of the cups are separate from the casting, soldered to their places, and have in their centers small openings to admit a tool for extracting wicks that may accidentally have slipped down into a cup, or to remove other obnoxious substances. These openings are closed by soldered caps. There isalso a similar opening, 1, closed by a screw-cap, in the top of the reservoir A, in which a wire may be inserted to clean the tubes 0 in case they become clogged.

The reservoir and oil-cups are supported by the frame D; Standing'on the outer edge of the same frame are the drums E, in which are caps lb, of the usual form, for creating a current of air on top and around the burners, to assist or secure combustion. A sufficiently Wide space is left open between the drums and the oil-cups for the admission and free circulation of air to prevent the heat of the flames from affecting the temperature of the oil in the cups.

In the accompanying drawing and the foregoing specification a double stove-#4: 6., a stove with two oil-cups and corresponding burners-has been represented; but the same arrangement is applicable to stoves having one cup and burner by changing and adapt-- ing its-outward form.

The object of my invention has been to produce a perfectly safe oil-stove without the interposition of water or other appliances-an oil-stove that cannot leak or be easily broken; and experience supports me in the statement that success has been the result of my endeavors.

I am aware that a horizontal tube screwed in the reservoir and cup to connect them has been used, and that my invention contains l'entures similar to others that are well known. enlarged portion of the casting, substantially :0
