Application filed June 11, 1920.- Serial No. 388,371

To all whom it may concern:

Be it known that I, Tniio'conn J. hfTI-GCHEL- .nnirrn, a citizen of the United States residing at Cleveland, in the county of (luyahoga and State of Ohio, have invented a certain new and useful lmprovcn'ient in.1,;l3urner Constructions, of which the following isa full, clear, and exact description.

This invention relates to a burner construction which is so constructed that the application of heat incident to burning a fluid fuel, beneath a receptacle being heated, is made directly to the receptacle and not through any considerable air space between the burner and receptacle, as is the case with usual types of burners.

The invention further contemplates a construction which can be employed with combination coal and gas ranges ot'a type wherein the anchor plate of the range serves as a common top plate whether gas or coal be used as a source of heat, the burners being a permanent structure in the range. I

Reference should be had to the accompanying drawings forming a part of this specification in which Fig. 1 is;a front elevation of a portion in section of the range embodying the present invention: Fig. 2 is in part a top plan and sectional view showing a portion of the range; Fig.8 is a top plan view of a burner; i l. is a sectional elevation showing a burner and cooperating plate.

Referring to the drawing, 1 indicates a suitable standard having legs upon which the body of the range proper is supported. At 2 there is .indicated an elevated or upright portion provided with doors 3 and 4 behind which are located respectively an oven and a broiler compartment.

Located centrally of the range or otherwise positioned, and depended wardly, is a fire box construction 5 which is provided with a usual lining 6. grate bars indicated in dotted lines at 7 and adoor 8, all of which are of usual construction. i

The top plate of the range is indicated at 9 and beneath the top plate there is a lower plate such as indicated at 10 and the space between the top plate 9 and 10 is closed in so as to provide a chamber which is in open communication with the fire box.

down- The rear wall of the chamber 11 is provided with openings such as indicatedat 12, whichopeningscommunicate with afliie passageway within a housing member 13.

no or more of these openings may be con+ trolled by a damper. l

The anchor plate 9 is provided with two openings, which openings are occupied by the removable plates 1 1 and 15. Each of the removable plates is-provided, with oneor more openings such as indicated at 16 in Figs. 1 and 4. I ithin the chamber 11 and b611821t11 -tl18 removable plate is located .a burner istruc ture which is generally indicated at 17. This burner structure as shown in Fig. comprises an endless hollow tube 18 which is connected with a supply pipe at 19. In the present instance the burner is annular in form corresponding with the opening 16 in the plate 14.

The burner structure with lugs such as 20 which the burner is directly attached to the removable plate such as the plate 14. p

The burner is located so as to lie just beneath the plate 14: and. extending around the edge of the opening in the plate. The tubular body of the burner is drilled with a plurality of holes as indicated at 21 each of the holes being located adjacent one side of the top of the burner anjd'the angleof the holes is such that the flame incident tomay be provided burning gaseous fuel is directed toward the center ot the openingl6inqtheplate 14:.

It will be noted that the flame from the burner is practicallylocated directly be-- neath the plate 14 and the flame directly contacts with the receptacle which may be placed over the opening 16. The distance between thetop of the plate 14 and. the holes 21in the burner is but arveryshort distance so that the flame and the hot gasesof combustion pass through a very limited air space in the application of heat. This results in a more direct application of heat and less wastage thanis the case where in the usual type of gas range the burner is located 2 or 3 inches below the top surface of the top plate of the stove and because of this distance a considerable amount of heat is'lost Due to the fact that in the present burner the holes are directed inwardly the flame shoots toward the center of the opening in the plate 14: and hence will substantially with the gas header 22.

said opening, means for supporting The burners being located directly be neath the top plate of the range may remain in the chamber 11 even though the burners are not in use but the heat supplied by the burning of fuel in the fire box 5.

lVhen solid fuel is used, the openings in the top of the plates let and 15 are closed by means of a cover member indicated at 23, which fits in each of the openings 16. Each cover is provided with a depending flange 24 which extends inside of the burner structure and so protects the holes in the burner from becoming filled or clogged with coal dust or ash dust when a solid fuel fire is used.

As will be understood, the pipes which connect the various burners with the gas header 22 are provided with the usual valve and air mixer construction such. as indicated at se Having described my invention, I claim 1. The combination with a top plate of a range, which top plate has an opening therein, of a burner comprising an endless tubular body corresponding in form with the said opening, means for supporting said burner directly beneath said plate and close thereto, said burner body having holes thercin which are positioned to direct a flame toward the center of the opening in the said plate.

2. The combination with a top plate ofa range, which top plate has an opening therein, of a burner comprising an endless tubu lar body corresponding in form with the said burner directly beneath said plate and close thereto, said body having holes therein, which holes are adjacent the edge of the opening in the plate and positioned to direct a flame toward the center of the flame in the plate. 1

3. The combination with the top plate of a range, which top plate has an opening therein, a removable plate" in said opening, said plate having an opening therein, a burner comprising an endless tubular body corresponding in form with the said opening, means for supporting the said burner from the removable plate directly beneath said plate and close thereto, said body having holes therein, which holes are adjacent the edge of the opening in the removable plate and positioned to direct a flame toward the center of the said opening.

4. The combination with the top plate of a range which top plate has an'opening therein, of a burner comprising an endless tubular body corresponding in form with the said opening, means for supporting the said burner directly beneath said plate and close thereto, said body having holes therein which are positioned to direct a flame toward the center of said opening and a cover adapted to .fit in the opening of the plate, said cover having a depending flange which extends inside of the burner body.

5. A range comprising atop plate, saidtop plate having an opening therein, means enclosing a chamber beneath said plate, a tire box which is in open communication with said chamber, a burner comprising an endless tubular body, means for permanently supporting the burner within the said chamber beneath the edge of the opening in said plate and close to the plate.

6. A range comprising a top plate, said top plate having an opening therein, means enclosing a chamber beneath said plate, a fire box which is in open communication with said chamber, a burner comprising an endless tubular body, means for permanently supporting the burner within the said chant ber beneath the edge of the opening in said plate and close to the plate, a cover adapted to close the opening in the said top plate, said cover being provided with a depending flange which extends within the body of the burner.

In testimony whereof I hereunto aflix my signature.

THEODORE J. MIGCHELBRINK.
