A'ITAGHlltIll-INTv FOR STOVES.

To all whom it may concern.

Be it known that I, CLARENCE A. NoTMAN, a citizen of the United States, residing at Alliance, in the countyA of Stark and State of Ohio, have invented a certain new andthe heat, and for distributing the same.

evenly, or substantially so, tively large area, whereby a large surface maybe heated by a single burner and the heat may be applied to a number of lutensils at the same time even though a single burner may be employed. I

OVBI a. Compara.-

Further objects of the invention are to' render the same simple and economical in construction and easy of application tothe stove proper.

In the accompanying drawings forming a part hereof, Figure l is-a perspective view showing my'invention applied to a stove of the vapor burner type; Fig. 2 is a perspective view on a smaller scale showing a portion of the radiating plate; Fig. 3 is a vertical longitudinal section through the stove shown in Fig. 1 illustrating the different parts in their proper arrangement with respect to the stove; and Fig. 4 is a perspective view of the heat-retainin and flame-directin or deflecting plate etached from the ot er arts of the stove.

In t e ordinary form of stove for burning fluid or vapor fuel, the burners are placed in the upper part of the stove andthe Hame is. unconfined, so that substantially no heat can be obtained therefrom unless the vessel to be heated be placed directly over the flame. In order, therefore, to maintain a number of yessels in heated condition, it is necessary7 to use a separate burner for each vesse which is, ofcourse, quite wasteful of fuel. By my invention, I am enabled to con-serve the heat and distribute the same over an eX- tended surface so that many vessels may be kept heated even though a single burner be employed and that burner turned very low, thereby accomplishing the same result with a small quantity of fuel that has heretofore required a much greater quantity thereof.

Taking up a more-specific description of my invention by reference to the accompaiiying drawings, in which the same reference character designates the same part throughout the several views, l represents a stove of any kind to which my invention may be applied. The stove itself, however,I forms no particular part of the present invention, it being understood that the invenl tion is applicable to stoves of almost any type and especially to those using fluid or vapor fuel. The stove shown in the .drawing is providedwith afuel supply pipe 2 which leads to any source of fuel supply. To the supply pipe 2, I attach inthe usual manner the burner pipes 3, which burner' pipes convey the fuel to the burners Il, each of which 4is attached to its respective burner pipe. The burners herein shown'are, so far as this invention is concerned, simply conventional, as I do not claim in the present invention any particular kind or style of burner. Above the stove plate or top 5 is located a metal plate or top proper 6, pref- .erably made of sheet inet-a1, which plate is spaced from the top face of the plate 5 by means of theside and end flanges 7 which,

in the instance shown, are made integral with the top plate, by `which arrangement a chamber is provided between the stove plate 5 and the cooking plate 6, which chamber is for the purpose of confining therein t-heair heated by the various burners 4.

For the purpose of directing the heat up- 1 wardly and through the open plates 8, I provide foreach burner a flange disk 9, which disks are seated or placed uponl the burner head l0, or are held in proper relation to .the burners in any other suitable manner.

. For the purpose of permitting-the air to pass upwardly and above the disks 9 for feeding the flame with the necessary amount of oxygen, said disks aie apertures 9, said apertures eing of sueient size to admit the necessary quantity of lair for combustion, the disks'being held b means of the tangs 11. The disks are pre rovided with erably cup'shaped, as shown, and-the coni cave faces of the disks upon their upper sides are so formed and located for better directing the flame upwardly, whereby the flame is properly guided and confined so that it. passes from the burner in-to direct contact with vthe cooking plate or `with t-he cooking utensil which may be placed in or over any aperture 13 in the cooking-plate.l

For the purpose of holding the plate 6 inpropervposition, I. attach to the flanges 7 thereon retaininu plates 12, which retaining plates may be of any desired form, extendingdownwardly so that their bottom or lower ends will extend beyond the lower edges of the flan es 7 in position to engage the outer edges of the stove plate 5. The to or cooking-plate 6 may be .provided wit any desired number of apertures 13, which apertures are for the purpose of receivin and holding cooking vessels-of any desired ind when it is desired to have'the lame of any given burner strike directly against the vessel. vIn the accompanying drawin s I have shown but a single aperture.

For tie purpose of closing theaperture 13, I .provide a'shutter-plate 14, whlch is pivotally attached to the top of the plate 6 in position to be swung over said aperture.

A burner to 'contact directly with the cooking `end lian It willbe understood that, bythe construction above described, I am enabled to heat thetop late 6 evenly whereby'a number of vse s` may be heated at the same time, and may permit the flame from any vessels `without materially decreasing the heat of the plate 6. It will also be underlstood that the top late 6 and the side and s 7 shou d be made of comparatively thm material; and, in order to prevent any sagging of the top plate, I may provide brace bars 15, which bars may be of the form shown. or of any other -suitable form, the only object of said bars be` to provide a sulicient-support for the top-p ate vso that it may carry the necessary weight without sag g.

While I ave shown a stove having a rectangular top plate, I do not desire to be confinedtov an particular sha e of such plate, asl it wil be understood t at the ob- ]ects of the invention may be carried into eect without regard to the form of the late. P As will .be understood, lefore a flame is 1i ted, the chamber below the cookingte is filled with cold air, which is a poor conductor of heat. That portion of the body of air in the chamber adjacent tothe flame will become heated, whereas those portions farther distant therefrom will remain cold or will heat very slowly unless some means be provided for directingv a current of heated 'airaway from the burner toward that desired to heat. For this purpose, I provide at suitable points, as in the flanges 7, a series of a 16, which may be closed either in w le or in by dampers 71 which are mounted on said a and are preferably ivoted thereto, as shown, If, therefore, the be lighted at the right hand burner, in

part ofthe cooking plate which it is 'with end of the cooking plate, the damper at or adjacent said end will be o cned, and the aperture 13 closed', either y the shutter plate 14 or by a cooking utensil. The air entering through the apertures 9 in the disk 9 of course becomes-heated by the flame and passes upwardly, displacing the air already in the chamber which passes outwardlyv through thevopen aperture 16, thereby creating a draft in the direction of said aper-f* ture and carrying the heatv from the' lflame in a direction to heat the desired part of the plate 6i Many changes in the specilic details of my invention may be made without departing from the principles thereof, and I desire itl to be understood that the following claims are not intended to be limited to such details any further than is rendered necessary by the specific terms employed, or by the prior lstate of the art( Having thus described my invention, I claim: y f
