STOVE Filed June 23, 193C' Bil Patented July 12, 1932 JOSEPH A.. SIGNORE, OF LOS ANGELES, CALIFORNIA STOVE Application filed June 23,

This invention relates to a stove and more particularly pertains to a portable gas burning stove of the heater type which is especially adapted for use in rooms of dwelling 51 houses, apartment houses and the like.

An object of the invention is to provide a stove of the above character in which the body of the stove together with the burner portion thereof may be formed integrally of a plastic composition and whereby the stove body and the burner thereof may be formed unitarily by molding operation.

Another obj ect is to provide a composition stove with an integral burner which is adapted to be formed in sections and in which the sections may be readily assembled into a unitary structure with the sections so mounted and arranged that they may be readily re moved and replaced.

Another object is to provide a stove which can be produced at small cost, which is subject to but slight deterioration and is accordingly highly durable, and which is capable of producing a maximum of heat with a minimum of fuel consumption.

Another object is to provide a construction in gas burning stoves whereby a gas burner and a combustion chamber or lire box may be integrally formed of a clay composition thus dispensing with the use of metal for this purpose as now generally practiced, thereby avoiding the disadvantageous features incident to metallic combustion chambers and burners, and obtaining the superior qualities of clay. Y

Another object is to provide a simple and effective support for the fire box and burner.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed and illustrated by way of example in the accompanying drawing, in which Fig. 1 is a perspective view of a stove constructed in accordance with the invention;

Fig. 3 is avview of the stove as seen in transverse section on the line 3-3 of Fig. 1 in the direction indicated by the arrows;

Fig. 4 is a detail in section as seen on the line 44 of Fig. 1 sho-Wing the manner of uniting adjacent sections of the stove.

Referring to the drawing more specifically, A indicates generally the stove body which includes a bottom wall 5, end walls 6 and 7,'

a back wall 8, and a top wall 9, which walls may be formedinone piece, or may be built up of several sections as shown in Fig. 1. The stove thus formed has the front side thereof substantially open throughout thereby imparting to the stove the characteristics l common to portable heaters having an open fire-box or combustion chamber. l

In carrying out the present invention, the stove body has formed integrally therewith a burner B which extends longitudinally of the interior of the stove at the intersection of the bottom and back walls thereof; the burner embodying a bore 10 from which leads a se- 75 ries of burner orifices 11 and which bore is adapted to be placed in communication with a so-urce of gas and air supply through the usual connection C embodying a nipple 12 for I connection with a gas supply pipe and which connection C includes a valve 13 lfor controlling the feed of gas to the bore 10 and also includes an air supply and mixing chamber 14 interposedv between the valve 13 and th bore 10. Y

An important feature of the invention resides in forming the stove body and the burner of a molded plastic composition, such as a mixture of clay and asbestoslibers,which plastic composition after being molded is dried and baked as is commonin brick and tile manufacture. Where the stove is built up of sections, it is Vpreferably formed with an intermediate section D, and end sections E and F which latter include the end walls 6 and 7 respectively, and the contiguous margins of the adjacent sections are formed to interconnect by over-lapped or broken joints as indicated at 15 in Fig. 4.

Formed on the inner face of the back wall 8 is a series of channels 16 with ribs 17 extending therebetween and which channels and ribs serve as flame spreaders the ribs also act as radiants. The back wall 8 and the burner orices 11 are so relatively arranged that ames emitted from at least a portion of the burner orices will be directed upwardly toward the inner `face of the back wall 8.

Formed on the upper face of the bottom wall 5 immediately forward of the'burner B, is a basin 18 adapted to receive a quantity of water where it is desired to generate water vapors during operation of the heater.

The stove body is mounted on a base Gr including legs 19' and embodying a plate 20 on which the stove body seats having a series of upturned ears 21 formed with in-turned upper ends 22 adapted to effect engagement with the stove body.

As a means for securely clamping the stove body in place on the base G, a clamping band 23 is passed around the stove body to extend over the ears 21, the ends of which clamping'band are secured together by a screw 24 in such manner that the band may be drawn suiiiciently taut as to effect secure engagement between the stove body and its base. y

The clay stove body is thus engaged only at its base portion which permits the upper portion thereof to freely expand and contract under varying temperatures to which it is subjected, thus minimizing the possibility of its being fractured by reason of its being highly heated.

I claim:

1. A stove comprising a plurality of stove sections each comprising a bottom wall, a back wall, and Ya top wall of integral formation and certain of which sections include end walls; gas burner sections formed integral with said sections and including in each section a bore and burner orices leading from said bore; a hase, and means for collectively securing said stove sections in assembled relation on said base.

2. In a heating stove, a stove body comprising hardened plastic bottom, end, back and top walls formed integral with one any other, a hardened plastic enlargementformed adjacent the juncture of back and bottom Walls and extending approximately the full length Vand above the plane of said bottom wall,said enlargement having a bore and burner orifices leading from said bore, and means for connecting said bore with a fuel supply conduit.

3. In a heating stove, a stove body comprising hardened plastic bottom, end, back and top walls formed integral with one another, a hardened plasticl enlargement formed adjacent lthe juncture of back and bottom walls and extending approximately the full length and above'the plane of said bottom wall, said enlargement having Va bore and
