ens-HEATER.

To all whom t may concern.' f

Be it known that I, GEORGE E. SHARPE, a citizen of the United States, residing at Steubenville, Lin the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Gras-Heaters, of which the following is a specification.

This invention relates to gas heaters, and has for its object the provision of an ineX pensive device which may be set inan open lire-place or used at any point in a room as a stove andin which the" fumes and currents risingy from the gas yburner will be caused tocirculate `in a path which willreturn them to a point immediately adjacent and above the burner where they? will be mingled with the flame and, consequently,

all particlespof carbon and similar matter consumed with an'economical iiowof gas.

The invention also seeks to improve the yconstruction of the heater to the end that the parts of the same may be readilyassembled and the device as a whole given an `ornamental* appearance,` the odors ordinarily `attendant upon the use of gas'heaters being overcome and the air within the room quickly raised to the desired temperature.

A further object of the invention is to provide a structure which may be connected A to a flue to carry off the products of combustion andto alsoprovidemeans whereby the mantel willbeproteoted whennthe device is locatedl ina fire-place. y n The invention is fully illustrated in the accompanying drawings and consists in certain novel features which will be rst fully described and then more particularly pointed out in the claims following the description. In the drawings: Figure l is a front ele vation, partly broken away, of a'heater embodying my present improvements; Fig. V2 is a vertical section of the same taken on the line 2--2 of Fig. l; Fig. 3 is a detail perspective view of a -portion of the shield which is interposed between the water'box or pan and the burner; and Fig. 4 is a detached perspective view of a portion of the upper damper orupper hood protector.

`Inl carrying outmy invention, I employ a housing l which is preferably of sheet metal and is cfa size to lit within a livreplace, as will bereadilyl understood, the said housing being of any desired dimensions and comprising a back, sides and a top, as will Specication of Letters Patent.A Y Patented Sept. 28, 1915.

be readily understood. I also employ Va front, which may be of any preferredvdesign,- and is preferably of cast metalv so as to possess the Vnecessary strength and durability. f

In the drawings, I have shown the front' as comprising an upper'section 2 having a hood 3 projecting forwardly and down-y wardly and secured to the top of the houslng by suitable bolts inserted through the iangey t of the housing and the section 2 of f rfi-an srarns rarfnnr orrren.

the front, as will be readily understood."

Belowfthe saidrtop section 2 are side mem-4 bers 5 which yare secured by suitable bolts to side iianges 6 of the housing, and rbetween the said side Vmembers 5 below the hood SisV isecured a screen or grille 6 which, in the illustrated form, comprises Va plate having vertical slots 7 and also provided with a downwardly and outwardly projecting hood 8 below the said slots. Between the lower ends of the side members 5, I secure thelower screen or grille 9 which, in the present drawings, is/shown as Vsimilar in appearance and constructionto the upper screen or grille 6 but which may, of course, be of any other de-` sign which may provide openings through which cold air may pass into the housing;v

The space between the hood 8 Aand the screen or Vgrille 9 .is open, as clearly shown in the drawings, and within the housing,A

back of the said open space, is a deflector`n plate 10 which is preferably constructed of sheet metal for the sake of economy and lightness and is provided with side iianges, indicated 4at '11, through which suitable bolts are inserted to secure the same to the sides of the housing. The front face of this delector plate is covered with asbestos, as

shown at 12, and near the lower end of the said plate is a passage 13 for heated cur-` rents, which passage may be a single slot extending across the width of the plate or a series of alined short slots or perforations. The upper end of the deflector plate is secured to an inner hood 14 which is suitably:

shaped to t within and constitute a lining for the` hood 8 and also provide a chamber 15, in which the heat may collect before p passing through Aa vertical flue or a series of fiues 16j into a drum 17 which islocated back of the upper end or edge of the screenA or grille 6. The drum 17 is supported by the upper ends of the fines 16 and is preferably constructed of sheet metal plates hav- 'y k'ing theiry meeting'edges interlocked in any desired mannerfas indicated at v18,V the said interlocking edges being brazedv or otherwise intimately connected so that tight joints will be provided. A short flue 19 leads from the back of the drum 17 through the back plate ofthe housing l, and this flue may be corinectedwithachimney or other conduit* to carry off the products/of combustion, if,

- desired. It is not necessary, however, to so -vconnectithis flue, and-ordinarily l close the outer end thereof byvlacap 2U. HIn rear 0f thel flues 16, I provide longer flues' 2 1 whichy openv at their upper ends into the druin 17 and extend downwardly from the said drumV f. in rear of the deflector plate and have H theirlowery ends opening into the boxor handle Inayjproject Vthrough the grille v921 lor may beotherwise conveniently located.

will be readily understoodthat the heated gas currents flowing from the box 22 will vbe turned upwardly by this lipv 25 so that instead of flowing across the burner 23 they will risevtherefrom and be fed directly into the flame.

A panter water boX 27 is secured the rear side of the grille 9 at the upper edge y [which bolts may be inserted tov secure it to the sidesof the housing between Athe same andthe ends of the water boX, the ends of the said shield being suitably shaped to fit Y closely to the sides of the deflector plate and vto the ends of the pan, as will be readilyv understood. The said shield isfalsopro.- videdwitha depending flange 30 which enters the waterl box, as shown clearly in Fig. 2, and thereby covers therear VVwall of the same.A Copper plates 311nay. also be placed Yagainst the sideportions of the deflector so as to cover the same and thereby add to. the ornamental heater. i c y The" upper grille vG "is so Vshaped or arranged as to provide anr open space 32be-v tween its'upper edge and the loweredge of the hood 3 throughwhich the heated air may vescape into 4the room above the Adrum 17,Y and to protect the mantelwhen the device is located VVVinY (a, fireplace If-provide Vthe shield or damper 33 which consists of av fiat sheet metalp'plate` slidably supported upon guides 34 secured tofthe sides ofthe housing l near1 the 4upper end thereof, the platev 33V being' provided with longitudinal flanges or ribs 35 at its ends to fit over the saidpguides 34, as shown in .Fi-g. 1.V It will also be noted@C from said-,figure that the` grille 6 Vispro-A vided. with small notches 3 6 at its ends to facilitate the entrance of the damper lorVv shield into position, andthe front edge of Y the said shield is turned upwardly,.as shown appearance of vthe at 37, and equipped with-,a handle 3 8 so thatit may be readily manipulatedand will be limited in itsinward movement by vtheisaid upeturned rflange engaging the Vfront facey of the lowerl edger ofl thev hood 3. To.V guardA againsty buckling of the said plate 33 at the ends of the same, I provide the keeper guides l 39 .which consistuof sheet metal Vplates secured tothe sides of thephousing and hav ing. their lower ends projected inwardlyy to extend over `theends ofthe damper plate, as clearly'shown.r l i f t-is thought the-use and advantages of may improved device will be readily under stood from the4 foregoing description takenA in connection with the accompany-ing dirawmanner and the flame willsextend", upwardly in front of the dellector plate, as is evident.4

.Theheat thrownout directly by thel flame will'be reflected .intol the4 room through the open space between the lower grille and the ilower hood, while the fumes of the-gasl willr pass upy through theflues 16 into the drum 17. ,From the drum 17, the gas fumes and ings.y Thegas is ignited in the*V ordinary the, productsK4 of `combustion wfil-lvdescendU through the iues 21 into the `box 22 and thence escape through the opening or open-vr ings 13 to the space above theburner.v The heat.Y from the flame will, of course, create an upward flow of air currents,and the lip 25 will prevent the currents from the box 22r passing across the burnerV and. will turn. the same upwardly thereby` actingrin conjunction with the natural suction created by the fla-me. The currents from the Haine will' thus be given circulation from the Y burner andback to the saine so that the odorfgiving particles will be consumedand a small supply ofgas will serve to. quickly n bring the temperature of the room to the desired degree. will pass through the lower grille or screen under the detiector plate Vand then rise within the housing around the flues 16 and 21 and the drum 17 and finally escape through the upper screen and over the upper edge of the same. If the heater be located in a lire-place, the shield or damper 33 may be drawn forward so that it will extend out beyond the hood 3 and will. thus serve to prevent the heated air from iiowing directly over the front face of the said hood 3 and against the mantel. They will be, moreover, thrown out into the room and toward the fioor of the same so that the room will be quickly heated.

it will be readily noted that the device effects two counter-circulations, the air of the room being caused to rise back of the deiiector plate and around the fines and drum and then escaping into the room from the upper portion of the heater, while the products of combustion and theA gaseous currents will be caused to rise through the iues 16 and the drum and then descend through the iues 21 and return to a point above the burner. rlhe drum and the flues, as well as the box 22 being constructed of sheet metal, will be quickly heated so that the fresh air currents rising around the samet will be quickly raised in temperature. rllhe drum 17 is, of course, spaced from the back of the housing so as to facilitate the circulation of the fresh air currents, `and it will be noted that the drum, the fines', the lower box 22, together with the defiector plate and the inner hood and heat chamber 15, will form one rigid structure so that the parts may be readily assembled when setting up the apparatus.

The provision of the water boxor pan 27 provides for the supply of a vapor above the burner to replenish rthe consumed particles in the gaseous currents, and the shield y28 between the pan and the burner will prevent the liooding of the burner when the supply of water is being replenished and will also impart an ornamental appearance to the device which will perceptibly increase its attractiveness. Moreover, this shield 28 and the side plates 21 beingof burnished copper will serve as rei ectors to throw heat out into the room and as the shield rests directly onV the burner close to the openings therein, it will become heated and, consequently, aid in the vaporization of the water in the box 27.

The cold air from the room Hector plate having an opening therethrough near its lower end, a heat chamber at the upperend of said plate in advance of the same, a drum above and spaced from said heatchamber and in direct communication therewith, a box on the back of said plate covering the opening therein, lues back of the deflector plate connecting said box with the drum, and a burnerin advance of the deflector plate adjacent the opening therein.

2. In a heater, the combination of a deflector plate having an opening therethrough near its lower end, a drum above` the deiector plate in communication with the space on front of said plate, a box on the back of the plate covering the opening therethrough and in communication with the drum, a guard carried by said deiiector plate and offset therefrom to project over they opening therethrough, and a burner below and 1n advance of said guard.

3. In a heater, the combination of a housing, a hood projecting froin the front end of said housing, a grille across the front of said housing below said hood, heating mem.

bers supported within the housing in rear of said grille and below said hood andY spaced from the housing, and a damper slid.- ably supported by said housing below the top of the same and at the lower edge of the Said hood.

4t. The combination of a housing, a hood ksecured to and projecting from the upper end of said housing, heating members supported within the housing below the said hood, guides upon the side walls of the housing, a slide mounted on said guides and proj ecting under and forward of the said hood, and keepers on the side walls of the housing adjacent and above said guides.l

5. rhe combination of a housing, a hood on the front of the housing at the upper end of the same, heating members within the ioo housing below and spaced from the hood, Y

and a movable shield interposed between the hood and the heating members and arranged to be extended in front of the hood.
