This invention relates to heaters, and it more particularly relates to an improved heater of the reector type.

f An object of the invention is to provide a heater of this character having a perfect .circulation of air, profperly distributed around the burner thereo ysa .A still further object of the invention is to provide air ducts orperforations through the walls of the heater in such relation to the burner and to the heatdeeetors with the heater, as to provide, heated air properly distributed within vthe heater, so that the radiation will be equallized'around t-he heater. y

Gther objects and advantages `may be recited hereinafter' and in the claims.

In the accompanying drawings which4 form a part of this application, Figure 1.

is a perspective View of my improved heater, certain portions being broken away, so as to disclose the interior arrangement, and, Fig. 2 is a vertical sectional view through the frontand back walls of the heater embodyingmy improvement.

eferringmore particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, l provide a stove body com risinga metal casing or box consisting of side walls 5, rear wall or back 6, an upper front wa1l7, a vlower frontwall 8 yand a top 9. The stove body is provided with ordinary legs 10, whereby an' air space is provided thereunder.

j The front part of the heater is provided with an opening between the portions 7 and. extendin approximately entirely across the body o the heater. The heater is also provided with side linings 11 and a cor- I rugated reflector plate 12, preferably of' copper uof copper-placed sheet metal. The side linings may be secured to the body by any proper means. The reflector plate is preferably secured to the lower front portion 8, by rivets, bolts or the like 13,` being also secured, at its lateral edges, to the rear and lower edges of the side plates 11. Instead of the reiector plate being secured at its top to the rear wall 6, as in ordinary heaters of this character', an air passage 14 is. pro-v vided therebetween, so that air may pass from the air space under the heater, up-

kward through the air passage 14.` To the upper' 'portions of the sides 5 is secured a substantially horizontal deflector plate 15, being slightly inclined upwardly toward the rear wall, and being curved upwardly at its rear portion. A forwardly extending de'- fiector plate 16 is secured to the rear wall, curving forwardly therefrom, over the rear end of the first said deflector plate. p.

An air passage 17 is provided between the top 9 and the deflector plate 16, an air passage or draft opening 18 being provided between the deflector plates 15 and 16. y

A burner pipe 19, is supported by the side walls 5 in thewell known manner, lava tips or jets 2O being secured to the burner pipe and constituting a part of the gas burner,

said gas burner being adapted to connect' with a gas supply, through the medium of a connecting member 21, a valve 22 of ordinary construction being provided for regulating the flow of gas.

The upper front wall 7 extends below the level of the gas burner. When the gas is turned on and lighted, air enfers the heater through the. open front below the portion 7 and supplies oxygen to aid combustion of the gas. However, if no other source of air supply were provided, the combustion would be incomplete, as this air supply would have the effect of forcing the flame up against' the defiector plates 15 and 16, thereby excluding air from the upper portion of the flame, so that a part 0f the smoke or unconsumed products of combustion would be deposited upon the defiector plate, as soot, the other part of the smoke passing through the air passage 18 and out into the room being heated. This smoking and sootlng in heaters, of ordinary construction, is welll known to be very objectionable; and 1n or.4 der toovercome this objection, ,E provide aA series 'of apertures or perfor-ations 23,

through the side walls 5, said apertures being arranged in approximately horizontal .seriesabove the level of the burner. I also the heated air and products ofcombustion' may pass from the passage 17, when desired, and I may also provide the top portion of the heater witlroutlet apertures 27, above the de'lector plate 15, to auxiliate the passage of heated air from the heater, so that a considerable volume of air will be continually passing through the heater while in use.

The objects of the perforations, above the burner, are to completely surround the flame with air, so that complete combustion of the gas will result; and to temper the heat adjacent to the walls of the heater, so that unsightly discoloration ot" the walls, by excessive heat, is avoided. Moreover, by thus supplying a large quantity .oit moderately heated air, the objectionable feature of intensely heated air rising rapidly to the ceiling is avoided; the advantageous difference between the operation of my improved heater and of ordinary heaters, being quite obvious, since the. moderately heated air spreads through 'the inhabited portion of the room, tempering the cooler air in the room; while more intensely heated air above the heads of the inhabitants, does not mix or temper the lower strata of air in the room, nor does it perform any desirable function.

ln opera-tion, the burner being lighted, air enters through the main. front opening and through the perforations 9A, and together with the force of the from -the burner jet carries the flame in an approximately hori-A zontal direction toward the rear wall of the heater; whereupon, air passing upward through the passage' 1e and inward through the perfor-ations 25, supplies oxygen to the. terminus of the flame and directs 1t upwardlythrough the passage 18; and so the a-ir, from the several openings and perforations, after absorbing heat from the Haine, passes out through the several openings above the detlector plane.

lt will be seen that l have provided a heater ot this character which is fully capable ot attaining the foregoing objects, andA in a thoroughlypractical and eilicient manner.,

I do notilimit my invention to the exact details of construction, combination and arrangement of parts as herewith described and illustrated, but my invention may only be limited by a reasonable interpretation of the following claims.

What I claim is':

1. The combination in a gas stove, of a hollow body having side walls and a rear wall and a front wall, said front wall having a relatively large front opening therethrough, a horizontal gas burner supported by the side walls and being located nearthe front wall above said front opening and adapted to direct a flame rearwardly, 'a forward deflector plate joined onto the front 'wall above said front` opening and extendin rearwardly therefrom, said front wall being provided with a horizontally disposed series of apertures communicating with the interior portion of the stove below said deflect-or plate and above said burner for directing a. mitigated current of air between said detlector plate and said flame, saidA burner being spaced apart from said forward deflector plate to a suiiicient extent for preventing flame contact with said plate, and an inclined rear defleetor plate secured on the rear wall .and extending upward. and forward so as to overhang the forward deiiector plate and to provide a narrow passa e therebetween said side walls bein rovided with outlet openings above the rearwardly extending dei'lector plate and' infront of the forwardly extending deiector plate, and said rear wall being provided with perforations slightly below the rear deiiector plate, whereby an air `current is establisjhed between said plate andthe dame and products of combustion from the burner.
