HEAT DISTRIBUTER OR'PLATE.

Patented Oct. 20, 191 5:.

Application filed February 26, 1913. Serial No. 750,767.

To aZZ whom. it may concern Be it known that I, STUART B. ll 11.1: a, a citizen of the United States, residing at (,Ihicage, in the county of Cool; and ritatc of Illinois, have invented certain new and uscful Improvements iii a Heat Distri intcr o Plate, of which the following is a description.

My invention belongs to that general ci. of devices known as heat distributers or plates, and relates particularly to a device for use in cooking and preparing food, which food may be in suitable utensils, or may be placed upon the top of the plate, depending upon the article to be cooked, or it may be used for heating articles other than food. The device is particularly adapted to be used for baking purposes in which case cover may be placed over the same, the material to be baked being placed under the cover. When the device is so em ployed, food may be baked on the plate as satisfactorily as in an oven. F

The invention has among its objects the production oi a device of the kind described that is simple, convenient, durable, eliicient, and satisfactory, and that may be manufactured and sold at small cost.

To this end my invention consists in the novel construction, arrangement and com'lnnation of parts herein shown and described. and more particularly pointed out in the Claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure l is a top plan view of the device. Fig. 2 is a cross sectional Vii-3W oi the same. taken substantially on line 2, 2 of Fig. 1. Fig. 3 is a sectional View of a portion of a modified construction, and Fig. T isa top elevation oi the same.

Referring to the drawings, my preferred distributer consists of a substantially flat top plate 1,. which is provided with two or more series'oi' holes or openings 2 and 3, arranged substantially as shown. The holes are of any preferred size, and there may be as many as desired, or as the space will permit. The top plate may be provided with. ribs, or ridges 4i and 5, and when the distribute! is made of thin sheet metal, as shown in the drawings, the ribs or ridges may be formed by corrugating the plate. In the construction shown. the ribs extend proximate to the center of the plate, and a space is left as at 6, in which the name of any suitable manner, when tle the manufacturer may oe placed. The ribs are adapted to support and raise the cool; mg utensils slightly above the plate 1, an alFu tend. to strengthen or stillen the top plate.

Iii-ranged below the top plate. a plate T, which is formed as shown most clearly 1'" 1g. 2, or in an equivalent manner, and

in extended or flanged asgat 8 about the periphery. This plate may be said to be convex, or concaYo-convet, with the cone-arc s1 le toward the top plate, so as-to form a heating chamber between the two. The cXtended flat flange 8 bears against or contacts with the under inc? of the plate 1, the same being of sulliciont width to extend 'l ronrthe pe riphery ol'the top plate to a point between the opei'iings or holes 2 and lloles J are provided in the flange 8, the same being of 7 the same size and the one in number as the holes 2, so that when the two plate" are cured together the holes :2 and register.

The two plates may be sccuretl together in l none; I

constructed of sheet metal. top plate 1 flanged downw and thence turned inmu'r brace a flange 10 on the flanges 1,0 and 11. when are quite still or rigid. an; the plate over a burner or course, understood that the struction is shown, in wl plateili is provided with slots 16, and a plate cured below the plate 13, ll a same cxte from and being seen. l to or: u points between the ends of the low two plates may be seen 18, or their eipiivalent on the top plate similar struction. This .con. .u operation to the other cr. explanation of the operation sullice for both. Assumin tl l1 positioned over aliaiue. r. n passes up through the holes same being directed to the holes b vex face of the lower plate. an. within the heater by the l'lang s ll) A portion of the heat is co ducted oi.. the'lower plate 7, and heats the plate 1, the excess heat passing out through the holes In some cases a top or cover prer-siously nicotinned is not desirable. With it, however,

pies, cake, bread, biscuits, or meats, and the I like, may be baked in the same manner as if no an'oven, and toast may be made upon the plate, or fiat irons heated thereon. A pan or pot will serve as a cover for baking purposes, or a special cover may be provided for the purpose.

Having thus described my invention, it is obvious that Various immaterial modificati'ons may be made in the same Without deli parting from the spirit of my invention, hence I do not Wish to be un'clerstood as.

limiting myself to the exact form,construe 1- tion, arrangement, or combination of parts herein shown and described, or uses mentinned. a VJ hat I claim as new and desire by Letters Patent is:-

1. A portable heat distributenfw cookto secure ing utensils comprising. a top plate having radiating ribs extending from a point adjacent the center thereof to a point adjacent the periphery thereof and also having a series of openings arranged in'alternate relation with regard to said ribs adjacent the outer terminal thereof, a lower substantially semi-spherically-shaped plate secured at its upper edge to the under surface of the upper plate at a point beyond the ribs and soles, the lower plate being adapted to re-- ceive the direct action of the flame and separated from the upper plate by an unob-. structed space, the upper plate having a depending annular supporting flange and the upper ancl lower plates having an annular serles of reg stered holes at a point adgacent said; flange, substantially as and for the purpose described.

2. A portable heat distributing i'nember comprising an upper plate having a down-i wardly pro ecting edge flange extending therearo'und to constitute a support, a concave-convex lower plate, the lowermost central portion thereof being substantially parallel to the lower edge of saidfiang'e, and the upper outer edge being in Contact with. the upper plate adjacent the outer edge of the latter, the lower plate being separated thev upper-plate by an unobstructed space" and said lower plate being free fromopenings leading into said space, the upper-plate having a-series of openings communicating with said space between the plates, and an auxiliary series of openings therethrough. adjacent the outer edge thereof in communication with the space between the under surface" or the lower plate and the inner surfaee of said supporting flange.

I 3 A portable heat distributing member comprising an upper circular plate, having a downwardly projectingperipheralsupporting flange, said upper plate haying t-Wo concentrically arranged annular series of openings acljacent'said peripheral flange, a lower plate having a concave-convex central portion connecting with a fiat peripheralportion at the upper edge thereof the peripheral flange of the upper plate having'a bent portion overlying the lower edge of said supporting flange of the lower plate.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses. v
