HEAT-DISTRIBUTING PLATE.

Application filed .Tune 28, 1923. Serial No. 648,326.

To all whom it may concern.'

Be it known that l, VILLIAM HANDLER, a citizen of the United States, residing at Jerseyville, in the county of Jersey and State of Illinois, have invented a new and useful Heat-Distributing Plate, of which the following is a specification.

This invention relates to a plate, which is adapted to be used for distributing heat from the flame *ofl an oil stove, or other source of heat, so that the same may be utilized in cleaning oil stove chimneys, whereby the` latter' will operate without smoking.

Many attempts have been made to devise an oil stove burner and chimney, which may be used without the formation of smoke or offensive odors, but nevertheless in all such constructions after the stove has been used for a time h-eavy oils, carbon, grease, and other byproducts of petroleum accumulate in the lower part of the chimney below the edge of the flame, where they are not subject to intensied heat, and are therefore heated only enough to cause the formation of offensive vapor or smoke.

It is the object of the present invention to provide a device which will be simple and inexpensive and may conveniently be used to facilitate the removal of such accumulations on the chimney, so that the same will operate as eflieiently as that of a new stove. By using my invention from time to time for the purpose stated, the oil stove will always be in a condition to work satisfactorily.

The structure of my invention and t-he principles embodied therein will best be understood from the following detailed description talenin connection with the accompanying drawing, which illustrates the invention in its preferred form, and the method of using the same.

In the drawing:

Figure 1 is a perspective view of a threeburner oil stove, with my invention being used thereon. I

Figure 2 is a detail view, partly in section, of the chimney being cleaned.

Figure 3 is an enlarged plan view of my invention with'port-ions broken away to illustrate the several layers thereof.

Figure 4- is a vertical section on the line ll--lr of Figure 3.

The oil stove 5, illustrated in Figure 17 has three burners G, 7 and 8, each provided with a chimneyf9 of the usual construction, having several normally concentric cylindrical walls 10, surrounding the central flue 11. In Figure 1, the chimney has been removed from Ithe position shown by dotted lines above the burner '7, and has been placed on the plate 12, which is constructed in accordance with my invention, and rests upon the grid 13.

The plate 12 is formed of upper and lower layers 14 and 15 stamped from thin sheet iron, or other suitable material, and the outer edge 16 of one of the plates ispreferably folded over the other, so as to form a smooth periphery. Immediately underneath the upper layer 14 is a layer 17 of Zinc, and between the latter and the lower layer 15 is a layer of asbestos 1S. These several layers are secured together at the edges preferably by rivets 19'. A handle 20 may be secured by one of the rivets. After these layers have been riveted together, a plurality of openings are punched therethrough to permit the flame from the burner beneath the plate to pass upwardly through the space between the walls 10. As shown in Figure 3, these openings preferably include a central opening 21, the shape of which is immaterial, and several series of concentric arcuate slots 22, the location of which will. be determined in accordance with the size and arrangement of the various passage ways through the chimney.

The use of Zine in a furnace for the production of vapor which will clean the soot from the flues is well known, and in the pressent invention I preferably use Zinc between the sheet iron layers 14 and 15, although this is not absolutely essential. rlhe layer of asbestos is preferably used underneath the zinc, t'o prevent the latter from melting and running.

When the plate 12 is placed on the grid 13, it causes the flames from the burner beneath to spread outwardly and to heat the entire plate. The hot flames will pass upwardly through the openings 21 and 22, and consequently a chimney placed above the plate 12 will be subjected to an intense heat especially at the bottom portion where the oil, soot, grease and the like have accumulated. These accumulations will all be burned olf in a few minutes, and the chimney will be as clean as when first bought.

As indicated in Figure 1, the preferred manner of using the invention is by placing it above the griddle oit one burner, while a chimney -from one of the other burners is cleaned. Thus, each chimney may in turn be cleaned from one of the other burners. lt will be understood, however, that the in i'ention may be utilized in other ways, the application of an intense heat to the plate l2 being the essential thing.

ln the foregoing description I have described specifically the preferred structure, by means of which this method of cleaning chimneys is carried out, but it is to be understood that various changes may be made in the structure thereof, as well as in the mannel' oi1 its application without departing from the principles ol' the invention as expressed in the appended claims.

That is claimed is:

l, A plate Jfor cleaning an oil stove chimney. Comprising two layers of sheet iron with a layer of asbestos and a superposed layer of Zinc between the layers of Sheet iron, the whole being suitably secured together, and having a series of openings therethrough including a. central opening, and a series ot arcuate slots arranged concentric to the central opening and of such radius that they will register with the respective ues of the. chimney when the latter rests centrally on the plate.

2. A plate for cleaning an oil stove chimney, comprising upper and lower metallic layers with a sheet of asbestos and a 'super`- posed sheet of Zinc between said metallic layers, all olf said layers having a series of openings therethrough which are so. disposed that when the chimney is placed centrally upon the plate they will register with the respective [lues through the chimney and permit the heat to pass therethrough.

ln testimony, that I claim the foregoing as my own, I have hereto alliXed my signature.

lVILLIAM HANDLER.
