OWEN TAYLOR AND CHARLES C, TAYLOR, or HUNTINGTON, wrisr VIRGINIA.

RADIANT BACK.

Application filed October 2, 1923. Serial No. 666,118.

To @ZZ whom t may concern.'

Be it known that we, OWEN TAYLOR and CHARLES C. TAYLOR, citizens of the United States, residing at Huntington, in the county of Cabell and State of lVest Virginia, have invented certain new and useful Improvements in Radiant Backs; .and we 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.

The object of the present invention is the provision of a radiant back for furnaces, ranges and other heaters for cooking or other required purposes, which may be molded easily of any suitable material, such as re clay or metal and which may be produced at a relatively low cost.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application:

Figure 1 is an elevational view, partly in section, of a gas stove having the oven and burners provided with radiant backs embodying the invention,

Figure 2 is a detail Asectional view on the line 2-2 of Figure l,

Figure 3 is a front view of a radiant elenient, l

Figure 4 is a sectional View of the radiant element on the line l-i of Figure 3,

Figure 5 is a sectional view on the liuc 5-5 of Figure 3,

'Figure 6 is a top view of a radiant ele ment,

Figure 7 is a detail sectional view on the line 7--7 of Figure l showing the parts on a larger scale,

Figure 8 is an elevational view of a radiant element forming part of a circular back, and

Figure 9 is a view similar' to Figure nated in the several views of the drawings by like reference characters. f

The cook stove illustrated' has vradiant backs applied to the baking and warming ovenand to the burnersl for heating uten-V sils for cookingand other purposes. ovens have the radiant backs applied to opposite sides wherebyto equalizevthe heatv and the burners have circular backs associated therewith. `The radiant backs whether straight, circular-or curvedl comprise ele- The ments substantially asy illustrated.k Theele.- 1 ments comprising the straight back have ltheir edges straight, as indicated most clearf ly in VFigure 2. The elements comprising the circular or curved back have their edges inclined, as indicated most clearly in Fig! ure l7, to admit of the elements ywhen arranged assuming a circular or curved outline. f

The radiant elements vare preferably of sectional formation to admit of their ready molding. The elements are elongated and when assembled occupy a vertical position with the edges of adjacentelements in contact. Each` element comprises a` rear section l and a front section 2, the :sectionsy being jointed to prevent displacement. The rear section 1 is hollow and .the space is closed at the top and open at the bottom as indicated most clearly in Figure 4f. The back wall of the space is formed with a series of concavities, as indicated most clearly at 3 in Figure 1i. The ridges or crests separating the depressions have points l extending forwardly therefrom to assist materially in radiating the heat. The vertical edge portions of the sides are grooved as indicated at 5 to receive tongues 6 adjacent the edges of the front section Zandthese meshing tongues and grooves provide joints to maintain the sections land 2 in proper position.

The front section mayy be` straight, Vas shownmost clearly in Figures 5 and 6, or curved as illustrated in Figure 9, but in each instance it is of open or latticed formation to provide an escape for ythe heat which is radiated by the corrugated or luted backs and the points projecting therefrom. As shown clearly in Figures 3 and S'the front sections comprise aplurality of cross bars 7 which result in the formation of L,diamondshaped openings 8 and opposed triangular' shaped openings 9, ,The crest orf" ridges Ico and the points et are disposed opposite the major aXis of a diamond-shaped opening 8 whereby to securea maximum discharge for the radiant and deflected heat.

As indicated in Figure 7, the radiant elements are of rsector formation and of such relative size as to occupy and forni a circular outline when assembled. The radiant elements may be molded of fire clay or other suitable material.

. Having thus described the invention, what we claim is l. A radiant back comprising upstanding segments forming an endless ligure', each segment having a front portion and a back portion in separableA relation and radial side walls, the adjacent side walls being in Contact with each other, an interlitting means between the side walls and both portions of each segment whereby the saine cannot accidentally turn relatively' to each other when assembled.

2. A radiant back comprising upstanding segments formingfan endless ligure, each segment having a front portion and a back portion in separable relation and radial 'side walls, the adjacent side walls being in contacty with'each other, an'interlitting means between the side walls and both portions OI" each segment whereby the same cannot accidentally turn relatively to each other when assembled, the front portion adjacent concavities having transverse rowsv of forwardly extending points. Y

In testimony whereof we a'HiX our signatures. Y
