To allwliowtc'tmayconcerm; Y

Be it known that I, RALPHS Twoeoon,

Y .a citizen ofthe `UnitedStatesfresidinglat' Berkeley, in the county of Alameda and ff Stateof Californiaghave invented certain new anduseful Improvements in Household Furnaces, of'whichthefollowing is a. speci-1 ication., h y I My'inventionfrelates to the class of fur- Ylo naceswhich, .especially intended vfor heat- Ving buildings,` are appropriately termed household furnaces. I

1 One objectV of my .invention'is to provide afcoin'bination" hot-air and hot-water or 15 steam furnace,1thus making use of the advantages of both types of `heating` systems.Y Another object of 'my invention Y1s to pro-V vide,1 in such a'conibination furnace, means forfapportioning, at' will, the heat derived 20,. from the combustion of the fuel, between the air and water heating'portions ofthe furnace."`Still another Objectis tofprovide a i furnace `having the'g'reatestl possiblether- Vmal efficiency.

My` combination :well adaptedfor use-insuch buildings as hotels, vin whichthe parlors', dining rooms,

and other public rooms, which mustV be kept warm continuously, are heated by hot an' leddirectlyfrom. the furnace, while the morereniotebed room `are'heated :by steauiV or hot water controlled at will bythe occupants.- iInsuchbuildings also, the use of my furnace, a `constant supply of steam isv available in the kitchen, laundry, and other service rooms. My furnace may also be used in the saine manner for heating residences, the halls, parlors, etc. being heated by'hot air led directly fromthe furnace located beneath theserooms, and the more remote bed rooms being heated by steam or hot water. i Y

My furnace isso constructed that the hot aseous products of combustion may `be'used rst for heating ,theV water for the hotk water or Vsteam system,`a'nd then alarge4 portion ofthe heat remaining in the hot gases,

which' is ordinarily lost in al simple steainf furnace, Vmay be used, forheating then air furnace -is particularly now fully describe by 4reference to the'accompanying drawings, wherein-- Figf l `is apartly brokenfront elevation of my furnace.'V y

` Fig. 2 isa vertical taken on the line2--2 of Fig. V3. Y

Fig.` v3 is a transverse vertical section .removable side wall blocks. A

V jFig 7 is a plan view, of a portionV of the deiieetor wall .overlying vthe fire-box.

y VFig-f8 is a section ofthe same, taken on.y the line 8--8 of Fig. '7.

Fig. 9 is a perspective view of a portion of the damper con-trolling means. F igrlO is a' vertical section of the lire-box, taken on the line 10,-10 of Fig. 2. Fig. ll is a sectional detail showing th section of Vthe saine,l

broken sectional'plan of the Y arrangement of the waterldrurns when the furnace is adapted for-hot water rather than steam heating. 2 A

In the drawings,the reference'numeral 1 designates the .outer shell or casing of my furnace, which is preferably made of brick or other similar `material to prevent unnecessary radiation of heat.` W

Within the 'lower left-hand portion of the casing, as viewed inV Figs. Vl and 2, is a lire boX 2, constructed in any well known manner in accordance with Vthe type of .fuel which is to be used.` .'Abovethere boX is a flat horizontal bafflev or deflector wall 3, Figs. 2 and 3, preferably constructed of refractory-'tile or lire brick, each brick 4 beingprovided upon opposite'edges with semicircularundencnt recesses 5, as shown in Figs. Z and 8, so positioned that the two recessesof adjoining bricks form a cylindrical.

.recess for thel reception of the head of a bolt 6, these bolts passing through and being securedto horizontal supporting beams 7, Figs. 2` 3, 7 and 8.4 ,Thus when the bricks 4g are assembled, they form a.con tinuous refractory baille, thus protecting. the supporting beamsw andbolts 6 from the heat of the fire.-

The deflector wall 3 extends far enough toward the right, away from the fire-box 2,

of fa pressure controlled 'regulating device 48. Said regulatingdevice may be of any -welliknown form, and is connectedbyfa `pipefl9 with the steam drum V12'. These parts are so connected that any decrease in steam pressure will open jthe damper', thereby `increasing the rate of combustion of the rire, and Vice Versa.,

, in the operation pass damper 20, Fig.` 2, `is set ina vertical position, thereby closing` the by-pass V19,`all Vthe hot 'gaseous products o'i' combustion pass over the waterv coilsv 9', and then through the airheating lues 22. It more heat isl desired from the hot air system, thedamper is moved to vopen said.. by-pass 19 slightly,

thereby allowing some ofthe'hot gases to pass directly to the air heating lues 2 2. At

thesametime the automatic regulator 48 opens the damper further, to increase the fire and keep the temperature of the steam Vconstant. It' no steam is required, the damper 2O can be set to bypass all the hot gas'es to the air kheating lues 22, and the damper 35 regulated by hand.

LA furnace comprising a shell; a uelburning member in the shell; Y aV deflector wall for the products of combustion overly-` ing said fuel burning member; an air-heating member within the shell overlying said deilector wall and exposed to the heat of Vthe products of combustion passing V.around the end of the delector wall, in their course to their exit romgthe shell; a'water-heating member at ,one side of the-fuel burning member4 and exposed' to therrheat from the Y products, of combustion passingrunder the deflector wall; and a damper disposed to selectively include and exclude said water heating AmeinberV fromfthe course Vofthe v products of combustion.V Y

`2;' A i'urnaceV comprising a shell; va fuelburning member inthe shell; a detlector wall Vior the products of combustion overlying sa'id fuel burning member; an a1rheat1ng member within'thershell overlying said de- :v flector wall and exposed to the Vheat of the of my infime. if. web# products of combustionpassing around the end of the deflector walhin their course to their exit from fthe shell; a water-heating l member at one side of the fuel burning member and exposed to the heat from the products of combustion'passing under the de- 'flector wall; and a damper disposed toselectively include and exclude said watervheating member from theV course of the products 4of combustion, and 'proportion their volume between said airheating and water Vheating members.

3. A furnace comprising a shell; a l'uelburning member in the shell; a deflector wall for the products or' combustion, over.-

lying said fuel-burning member; an air heatingmemberwithin the shell overlying said derlector wall; and lues extending substantially horizontally through said air- Vheating member for receiving the products of combustion passing around the end of the deilector wall and conducting them through said lair heating member in their course to their exit from the shell.`

4f. A furnace comprising a shell; a 'fueh burning member in `the shell; a detlector wall for the products of combustion overside'of the fuel burning member and ex` l posed to the heat from the products of combustionpassing under the delector wall; and a damper disposed to selectively include and excludesaid water-heating member from the course of the products of combustion and proportion their volume between said airheating and water-heating members.

In testimonyV whereof l have signed my name to this specication.
