GAS HEATER FOR FUR/NACRE., STOVES, 0R APARTMENTS.

Application iled September 13, 1922. Serial No. 537,339.

To all whom t may concern.'

Be it known that l, THEODOR E. KREU'rzER, a citizen of Germany (having resided in the United States one year last past), and having declared my intention of becoming a citizen thereof, residing in the city and county of Philadelphia, State of Penns lvania, have invented a new and useful Gyas Heater for Furnaces, Stoves, or Apartments, of which the following is a specification.

My invention consists of a device embodying a burner adapted to burn effectively commingled inflammable gas and air, the device being appliable in a furnace, stove or elsewhere, the construction of the device being such that the heat is generated in a largel vo u me and of high temperature and adapted to be directed from the furnace, etc., into an apartment or apartments, the device obviating the use of coal, wood or other fuel, and the expense thereof, while also avoiding the usual attention to a furnace and the-care of its ashes. v

The invention is satisfactorily illustrated in the accompanying drawing, but the irnvportant instrumentalities thereof may be varied, and So it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents. a to or plan view partly broken away of a gas urner embodying my invention.

Figure 2 represents a partial side elevation and a vertical section thereof.

Figure 3 represents a side elevation thereof on a reduced scalej showing also the outlines of a furnace-in which the heater may be placed.

Figure t represents a section of a portion online t-d Figure 2.

Similar numerals of reference indicate corresponding parts in the gures. Referring to the drawings 1 Adesignates the base of the burner, the same being a `hollow body ofmetal or other suitable material composed of the bottom plate 2 in the Acentral portion of which is ,theA4` air Hue', 39 the. wall of `which forms the er periheral rim 4l which rises from said plate 2. isi'ng-'from the outer periphery of said plate is the exterior rim 5,4 said plate 2 and said inner and outer rims t and 5 'thus forming an annulue.

0n plate Gwhich is rested on the rims t and 5 and secured to the bottom plate 2 by 4the bolts or screws 7 which pass through said plates and are provided with tightening nuts 8.

lin the centre of said plate 6 is the opening 9 which is in communication with the Hue 3. Connected with the side of the rim 5 is the top of the .ibase 1 is the covering H the gas supplying pipe 10 in the length of l .plied with commingled gas and air from the interior of the base 1 as is evident.

Above the base is the plate 1 3 of metal or other suitable material and above the latter is the plate 14 of metal or other suitable marial, said plates being horizontally arranged separated from. each other and from said base, and are securedn position by the bolts or screws 15 which -pass through ears 16 on the plate 13, ears 17 on the plate 14, and ears 18 on the base, and tightened in position by nuts 19 whereby the plates 13 and 14C are held elevated firmly above thebase.

ln the plate 13 are the series of vertical perforations or fines 20 and in the plate 1t c are the series of vertical ports, openings or dues 21 the parts being staggered in the two plates and! are designed to allow the products of combustion and air to pass upwardly through the same and traverse the undersides of said plates respectively in zigzag direction from the sets of orts in the plate 13 to the sets of ports in the plate let and thus eectiv'ely heating said plates 1t and 13. f l v 4 lln the outer peripheral wall 5 of the body are the outlet ports 22 which lead from. the

interior of the body and allow the commingled gas and air to escape therefrom at the outer periphery of the body and to be consumed .with that of the burners 12.

In the inner peripheral wall t of the body are the ports 23 which lead from the interior of the body and allow the coled and as to escape therefrom at the inner perip ery of the body and to be consumed with that at the burners 12.

'It will be seen that owing to the large voluines of gas andl air supplied through the burners 12 and by the two courses respectively at the exterior and centrally of the body due to the ducts 22 and 23 when the gas is ignited at the burners, the products of combustion are impacted against the plates 13 and 1d and passed through the perforations of said plates thus intensifying the heat of the latter and as large volumes of air are furthermore supplied to the burning gas and air the resultant heat is of a large volume and of high temperature and so a rfect combustion is produced, the same ein inodorous in its nature, thus obviating ,in apartments the objectionable smell or odor heretofore created in other l gas heated devices of the class.

As the covering plate 6 is a separate mem- `ber from the base it leaves the latter comparatively cool and so keeps the gas and air pipe 10 correspondingly cool. 'll`he perforations in the plates 13 and 1d allow the products of combustion to pass through them. This assisted by additional air which also .enters said perforations increases the heat of said combustion thus greatly raising the temperature of said heat as it leaves the device and also consuming the fumes of the combustion whereby said fumes are destro ed.

'l e air intake 11 consists of a slotted valve plate 2d stationarily connected with the gas supply pipe 10 and a slotted valve plate 25 rotatively mounted on the neck 26 and placed against the outer side of said plate 2d, so t at. .by rotating said plate 25 the slots of the two plates may be placed in and out of register so as to adjust the amount of air admitted through the plate 24 and entering the pipe 10, or to cut it od from Athe latter when so required.

The body of the device and its connected appurtenances will be supported in the furnace, stove, etc., in any suitable manner.

Having thus described my invention what ll claim as new and desire to secure by lietters Patent, is

1. lin a gas heater, a hollow base coinprising a ottoin plate having centrally therein a vertical peripheral rim forming a ilue, and aii exterior rim and a covering plate resting on said rims and secured to said bottom plate, said covering plate havin centrally therein a flue coincident with said ue of the Fbase and being provided with gas burner grices, said base havin connected with 1t a g supply pipe, orated pates elevated a ve said cove g late,

lt-like members connected with sai base and rising therefrom and connected with said elevated plates, and tightenin nuts adaptin said plates to be supporte sep'- arately roin each other and from said base.

2. lln a gas heater, a hollow base comprising a bottom plate having centrally therein', m

'the base and being provided with gas burner orilices, said base having connected with it a gas supply pipe, perforated plates elevated above said covering plate, said elevated perforated plates having ears peripherall thereon, bolt-like members in said ears, andy tightening nuts on said members contiguous to said ears ada ted to connect said elevated perforated plates with said base and support the former separate from each other and from said base.

3. ln a gas heater, a body adapted to receive inainniable gas, the saine being of the form of an annulus having outer and inner peripheral walls, a supply member for commingled gas and air connected with said body, a gas burner on said body, a plurality of perforated plates sustained above said burners, means passed through said plates and through the base of the body for supporting said plates in spaced relation, said ody having therethrou `h an air flue formed by the inner perip eral wall of said body, said wall of said due having therein gas outlet ducts if ing from around the upper edge of the body, and the outer peripheral wall of said body having therein gas outlet ducts le il l g from around the upper edge of said body toA said lburner.

4. ln a gas heater, a body adapted to receive inammable gas, the same being of the form of an annulus having outer and inner peripheral walls, a gas supply pipe connected with the outer peripheral wall thereof, the inner wall thereof forming through the bodfy an air flue, and 'a closing plate on the top of said body separate therefrom and restin on the top of the inner walls of said y and retained in position on said body, said plate having therein an air passage which is in communication with said air flue, a plurality of separated plates above the closing plate, all of said platee havine peripheral ears coincidentall arrang and bolts passed through sai ears and holding au of said plates in speed relation.
