Specification forming part of Letters Patent No. ilbl, dated August l, i876; application iiled April 10, 1ere.

To all ywhom yit may concern:

Be it known that I, ALBEN GULLIFonD, of Cleveland, in the county ot' Cuyahoga and Stute of Uhio, have invented certain new and useful Improvements in Stoves designed for employing coal-oil, Sac., for fuel; and I do hereby decla-re the following to be a full1 clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference heilig had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in stoves designed to employ coal-oil or the like as fuel.

In the drawing, Fig. 1 represents, in vertical section, the ditierent parts of my stove detached, and in the order ot' their adjustment from top to bottom. Figs. 2 and et represent plan views ofthe same. Fig. 3 represents, in vertical section, the said parts as adjusted and forming my stove complete.

My invention consists ofthe following parts and combinations, as hereinafter specified and claimed, wherein A is the oil-reservoir, rest ing either upon `legs or upon a ventilated rim, A', so as'to admit o t free admission and circulation of; air beneath it. Through the bottom of the reservoir A arepenings (t, and through the reservoir rises upward the tine a.

A wick-tube is located outside of the flue a', forming an annular air-space between them, which space is utilized for Ventilating purposes, and opens at its upper end by several mouths into the main tlue a. The wicking is inserted in its tube, and extends downward into the oil-reserveir A. Surrounding the wick-tube is another wall or wick-tube, C, rising to the height equal to or exceeding` the height of the reservoir A. This wall serves the double purpose ot' preventing the escape of oil from the reservoir A, and of providing an air-space between the oil and the wick-tube.

The parts just described are shown in Figs. l, 2, and 3 of the drawings, and constitute what may be termed the bottom section 7 of my stove.

Proceeding now to what may be termed the middle section, D D are two cylinders,

united at their base, and diverging from each other as they proceed upward. The inner cylinder D is provided with perforations d, whereby air is ad mit-ted tothe space between the two cylinders.

E E are lugs, crossing the space between the cylinders D D', for a purpose which will hereinafter appear more fully.

From the upper rim of the cylinder D projects a tlange, F, so constructed as to operate as a cover to the reservoir A.

The parts just enumerated and described constitute what may be termed the middle section77 of my stove.

Referring now to t-he upper section, G is a cylindrical extension, terminating in two similar and opposing cams. These cams, resting upon the lugs E E, will operate to raise or lowerthe superincumbent attachments as they Aare turned one way or the other.

From the upper rim of the cylinder G projects at an angle an annular perforated flange, G. This flange G', at its outer rim, is united with the crownplate H, whose center is pierced with an opening somewhat greater than the diameter of the flue a.

Between the perforated fla-nge G and the crown-plate H is a perforated partition, H', having acentra-l opening somewhat larger in diameter than the line a'. The outer rim ot` the partition H unites in connnon with the junction of the crown-plate H and perforated tlange G. The portion surrounding the central opening is so attached to the outer rim of the caurcylinder G as to permit a free circulation ot' air through and around it.

At or near the junction-ot' the perforated tlange G' and the crown-plate H may be provided one or more handles, hf, for turning the upper section ofthe stove.

l will now proceed to describe what l term my internal dctlector,77 which consists of structed of mica, glass, metal, or any suitable material. g

Operation: The reservoir A is lilled with the desired amount of oil, and the parts united, as shown in Fig. 3 of the drawings. The wick B, by the ordinary operation of capillary attraction, draws the oil to the upper exit of the wick-tube, where it is burned. Air is received through the perforated rim or base A', beneath the reservoir A, and is conducted through the flue a, and between its inner wall and the wick-tube, and also outside of said wick-tube, in such a manner as to amply support perfect combustion, and at the same time to keep the wick-tube sufeiently cool. The air passing up the flue inside the wick-tube meets the oonvex reector, and is projected upon the inner side of the llame, affording sufcicnt oxygen in that quarter, while the air admitted to the outside of the wick-tube acts partly to keep the wick-tube and oil-reservoir cool, and at the same time to afford oxygen to the outer surface of the flame. Additional oxygen, however, is received through the perforated flange G', and, being conducted through the perforated partition H', is so deected and directed by the crown-plate H as to act in such a manner upon the outer surface of the ame that, in combination with the action of the air upon the inner surface of the said flame, a perfect combustion is accomplished. By turning the upper section of thelstove, through its handles h, the cams upon the cylinder G, resting upon the lugs E, will operate to raise or lower the upper rim of the cylinder G, in such a manner as to impinge more or less upon the outer surface of the wick, and thereby increase or diminish the amount and intensity of the llame.

Although notan essential to perfect combustion, I prefer employing the chimney' K, which, aside from its operation as a flue, may act as a support for anything to be heated.

What I claim isl. In a eoal-oil stove, the combination with the reservoir, having a ventilated bottom and a central flue, a', of an outer wick-tube, the outer wall of which is cut away to allow the wicking to extend outward on the bottom of the oil-reservoir, substantially as and for the purpose set forth.

2. The combination of the cylinders D D', cover F, and reservoir A, substantially as shown.

3. The combination of the cylinders D D', lugs E, or their equivalent, and the cam-cylinder G, substantially as and for the purpose shown.

4. The combination, with the wick-tube, of the lugs E or their equivalent and the can1- cylinder G, substantially as and for the pur-l pose shown. y

5. The combination of the perforated flan ge G', perforated partition H', and crown-plate H, substantially as and for the purpose shown. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
