HEATING STOVE.

Application filed November 23, 1921. Serial No. 517,204.

To all whom it may concern.

Be it known that we, EMANUEL B. ADLER and JEROME Annnn, citizens 01"" the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania,

have invented certain new and useful lm-' provements in Heating Stoves, of which the following is a specification.

This invention is for improvement in stoves, and particularl gas stoves oi the type having an open front designed to emanate radiant heat.

Stoves of this general type are well known, and are in extensive use at this time. As now generally made, they comprise a back wall made or a thick mass of lire clay in the front, and at the bottom of which, are a'plurality of burners. In front of the back well, and arranged over each burner, is a mantle in the form of a vertical cylinder which is made up of two semi-circular parts, cemented or otherwise secured together. The rear part has a solid wall from which project a plurality oi integral points arranged to be heated from the burner and become incandescent. The front section has anopen grille otornamental design, through which the flame from the burner and incandescent parts of the back wall are visible, and through which heat may radlate.

both sections are made from some retractory earthy material, and are very fragile, so that they cannot be handled or shipped without great loss through breakage. Furtherm0re,they are expensive "to make and assemble. The back wall of the stove, being termed of a heavy mass oi fire clay, absorbs and retains a largeamount of heat.

The present invention has for its principal objects to provide an improved stove which may be more cheaply and easily made, and in which the mantles can be produced of metal rather than refractory material, and are formed as a" unit rather than as a series oi individual cylinders, as heretofore used.

These and other objects are attained by the novel construction and arrangement; of parts'hereinafter more fully described in connection with the accompanying drawing, in which:

Fig. 1 is a front elevation of the stove;

Fig.2 is a vertical transverse section on 7 line llll of Fig. 1;

Fig. 3 is a horizontal section on line lill lllT-Of-Fig. 1;

Fig. a is a front elevation showing a part of the stove removed;

Fig. 5 is a perspective view of a portion of the stove showing a sheet metal plate which is used to provide points adapted to be heated to incandescence;

6 shows in perspective the manner in which the plate shown in Eig. 5 is used;

Fig. 7 shows in perspective a modification.

In the drawing, A indicates a single casting which forms the main part of the stove structure. The casting provides a back wall 5.. forwardly extending sides 6, legs 7, vertical cover plate 8, and a horizontal base 9 joining the top of cover portion 8 and the base of the back wall 5. The back wall 5 has a forwardly extending portion lO-along the top thereof, which portion in turn has a rearwardly inclined coping 11. The front face of the back wall 5 is preferably pro vided with a series of vertically extending spaced apart ribs 12. Between the ribs, the back wall is preferably'iormed with a plurality of holes therethrough arranged according to a predetermined design. In base portion 9 is a series of holes 14, one hole being positioned centrally between each pair of ribs andonly a short distance in front of the back wall.;llear legs 15 may also be cast integrally with the piece A.

Disposed beneath the base 9 is aburner tube 16 (ii-"the shapeshown, at one end of which is a miner 17, and on the topof which are a plurality of burner jets 18, one jet for each opening 14.

The front cover plate for the front of the stove comprises a single casting B. This casting is approximately as long and as high as the vertical back wall 5, the front surface of which it substantially covers. It is preferably in the form of a plurality of integral, vertical, semi-circular columns 20 having an ornamental grille therein. Between the semi-circular parts and projecting inwardly, are ribs -21 adapted to register w th a seat upon ribs 12 on the back wall. The cover plate B is held against the back wall in any suitable way, as by bolts passing through it and the back wall. The bolts are indicated 22. This construct on provides in effect a series or" separate vertically extending hollow columns or flues having a burner jet disposed centrally of the bottom of each column, the fronts of the columns being open.

sponding to the 'wall. The ends of the points will project but a slight distance lnto the hollow columns,

and beingformed of relatively thin sheet metal may quickly be heated to inc ndescence.

This arrangement is cheaper and better than casting small projections on the back wall because of the difficulty of flowing the cast metal into such fine recesses when casting them, although it may be done, as indicated in Fig, 7, in which 5 is a back wall having integral points 24 cast thereon. Furthermore, after being used one or two seasons, the points may burn off, and by providing replaceable sheets, a new sheet can be easily substituted when the points are burned.

' The back Wall, front cover member, and projections areall coated with a fireproof white paint, which will add to the appeai 'ance of the stove, giving it th a ipearanre of being; formed of a heat resistant earth, the coating also serving to increase the radiation and reflection of lightand heat, and to protect the parts from .b'urn'i 11g and oxidization. i

A sheet metal casing 25 may be provided forenclosing the back. This adds to the appearance of the stove and provides a fine at the rear of the back wall where cold air, entering at the bottom, will rise and contact witli the back wall and be heated, missing out'the perforated top.

The forwardly extending top portion '10 serves to throw the heat outwardly, while portion 11 is providedprimarily for ornamental purposes to partially close the top of thestove and give it a finished appcarance.

stove constructed as herein (l61flillb6tl can be produced commerci ly', cheaply and easily. The cast iron front cover can be made much re cheaply than the cl L earthy main -s heretofore ,used, and the same degree of care in usingit is not neces sary. There are but few parts, and are readily accessible.

Various changes in the details of mustruction and arrangement are within the contemplation of our invention.
