FIRELESS STOVE.

Application led February 19, 1920. Serial No. 359,828.

T 0 all whom it may concern:

Be it known that I, GEORGE A. TAYLOR, citizen of the United States, residing at Muncie, in the county of Delaware andState of Indiana, have invented certain new and useful Improvements in Fireless Stoves, of which the following isa specification.

This invention relates to improvements in fireless stoves of the type which consists of an outer case, and an inner case, with heat insulating material interposed; the con-'1 tainer so provided being intended to maintain the temperature of the article placed therein.

To provide a tireless stove by whichy the temperature of the material-s placed therein may be maintained, and in which the actual cooking of foods may be accomplished, are the objects of this invention, and it consists of the new construction, combination and 'arrangement of parts and the features of improvement, shown in the annexed drawings, and described in the present specification. The invention is defined in the appended claims.

The several parts of the invention are identified by suitable characters of reference applied thereto in the different views in the drawings, in which- Figure l is a perspective view of one of my improved tireless stoves, the two-well size.`

Figure 2 is a frontal view, portions thereof being broken away and one end of the device being shown in central longitudinal section.

Figure 3 is an end view of Figure l, the lid or closure plate of the stove beingat closed position. y

Figure Il is a top plan view of the stove, a portion on the top plate, and of the cover lids being broken away.

Figure 5 is an enlarged detail view of the vent device.

Figure 6 is a transverse vertical sectional view of the lid.

My present invention is embodied in the preferred form and construction shown. In the model illustrated, namely-the two well size, the body may be thirty inches in length, fourteen inches wide, and fifteen inches in height. This box shaped body comprises a sheet metal wall plate having the side portions A, A, and the end portions B and B. The top `plate C made of sheet metel, preferably aluminum, and provided with circular openings, has its edges secured to the top edges of the side plates A, A, and the end plates Band B. O designates the bottom plate. Each of the cylindrical wells D, made of sheet metal, preferably aluminum, has itsy rim secured. to the edge of the circular opening in the top plate C., Adapt-` ed to reside immediately in contact with the bottom lof the` well D is a sheet metal disk E. This disk may be made of steel or other metal and its function isto form a reinforcement for the bottom ofthe lwell cylinder. To avoid electro-chemical activity between the two metals, this disk is subjected to a coating of asphaltum or other electrical insulating compound.

The frame for the aforesaid sheet metal body consists of a combination of wooden strips F, G, and H, suitably connected together and adapted to(` brace and stien the sheet metal sides A and the end plates B.

In completing the assembly of the several parts constituting my improved tireless stove, the structure just described, is disposed at inverted position on the workers bench; cylindrical sleeves K of sheet metal are then disposed at position, the` rimsK1 of same being disposed at contact with the underside of the top plate C. The sheet metal disks E aredisposed at place in contact kwith the bottoms of the well cylinders D and D. It will be observed that the diameter of the sleeve K is sufliciently greater. than that of the well cylinder D that the space I is provided, and in which the non-A circulating air so contained, is the insulating medium. Additional insulation between the sleeve K and the wall plates, consists. of-a wrapping L made of a succession of layers of corrugated or cellular paper or composition, and which wrapping fills the space between the sleeves K and the wall plates, and being retentive of the air, constitutes effective insulation for the well cylinders. It is contemplated that cellular tissue of other material may be used, the object being to have an air space therein partitioned in such manner that any circulation of the airso confined, is prevented, and such air constitutes the main medium ofinsulation. The corner spaces of the body are then packed tightly with eXcelsior Mor other suitable resilient light packing material.

Immediately at contact with the disk E is placed a filling of fireproof material such as mineral wool N, and it insures proper insulindrical container inside and of diameter less than that of the tubular sleeve and having its upper rim opening through the said top plate, and a closure plate for the said opening.

2. A tireless stove, comprising a box shaped body, a top plate, an open sleeve extending from the bottom of the body to the top plate of the body, a metal plate to tit in and slightly above the bottom of the said sleeve, ireproo insulation between the said plate and the bottom plate of the body, heat insulating material surrounding the said sleeve, a container inside said sleeve and having its upper end opening through the top plate, said container being of a diameter less than the diameter of said sleeve and to'provide an air space between the container and the sleeve, and a closure lid for said container.

3. A iireless stove, comprising a box shaped body, a top plate, a tubular sleeve extended upwardly from the bottom plate to the undersurface of the top plate, the lower end of the sleeve being cone shaped, a sheet metal disk electrically insulated and of diameter to be wedged into tightened osition in the coneshaped portion of the tu Eular sleeve and slightly above the bottom of the tubular sleeve, a container of diameter less than that of the tubular sleeve, lireproof material between the disk and the bottom plate of-the body, layers of cellular insulating material between the sleeve and the walls 1 of the body, and packing between the cellular insulating material and the walls of the body.

4. A lireless stove, comprising a box shaped body, a top plate, an open sleeve extending from the bottom plate to the underside of the top plate oit' the body, a metal plate to fit in and slightly above t-he bottom of the said sleeve, ireproof insulation between the said metal plate and the bottom plate of the body, heat insulating material surrounding the said sleeve, a container inside said sleeve and having its upper end opening through the top plate, `said container being of diameter less than the di-` ameter of the said sleeve and to provide a f `a closure lid of hollow construction and hav-` ing a resilient bottom plate, stalling for the interior of the lid to maintain the bottom plate of the lid at normally bul ged position, and a clamping means to draw the lid to tightened engagement with. the top plate of the box so that the surface of the said top plate immediately surrounding the rim or mouth of the containeris sealed.

In testimony whereof I aliix my signature in the presence of two witnesses.
