Be it known that I, ROBERT W. DODGE, a v, citizen of the United States', residing at Kansas City, in the county of Jackson-and- State of Missouri, have invented a vnew and useful Heating Stove or Furnace,pof which thefol-. lowing is a specication. f i

. This invention relates to heating` ,stoves or furnaces, and has for its object to simplify and improve the construction of such devices and effect areduetion in thefoonsurnption of fuel and an increase in thev heatgenerated;` and the invention consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims fol-f lowing. f, V Y

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is avertical sectional side elevation of the device when employed as a heating-stove; Fig. 2 is a plan'viewwiththe dome removed.l Fig.43' is a transverse section on the line 53 3 of Fig. 1'. Fig. 4 is a plan view of the grate detached. Fig. 5 is a side elevation of they stove in the Y reverse position to that shown in Fig. 1 with-v inclosing vjacket or shell in vertical section as employed when device `is used asa furnace.- Fig. 6 is a transverse section on the Aline 5 5 of Fig. 1. Fig. 7 is asectional detail of the lower portion of the lower shell-section, illus-y trating more fully'the mechanism for rotating the fire receptacle and grate.

The improvement herein disclosed may be applied to any size of heating stoveor furnace,

and for the'purpose of illustration kitis shown applied to a heating-stove of` ordinary proporl tions having an .inclosingg lower vshell-sectionA 10, provided with the nre-receptacle'111 and' with a grate 12 and ash-pit 13 in the usual re lative locations.y The lower section 10 will preferably be of cast-iron andlwill .be surmounted with-an uppershell-section 14, preferably of sheet-steeland supported, asi-at 15,; upon the lower section and from which the MlditionalA smoke-exits 17 may be providedv t'o V.provideV for the discharge at different points or for ay plurality of discharge-nues, if required.;V The; upper edge of the lower section 10'isformed- With-an inwardlyextending annular ange La 18, in .which spaced sockets arearran'ged to' `receive hearing-halls` V19, upon whichan outwardlyextendingiiange 2O on theupper edge of theflre-receptaole llwrestsfsotllat the iirereceptacle may he rotated asrequired and with tlie'mnim'u'miof friction.: L

l l The annular lflange 21,-betweenthe ash-.pit

13 andthe space'surroundingthe fire-cham ,ben isv providedwith spaced sockets to receive Ebearing-balls 22, -upon whichmhef outer edge of the' grate 112 rests yto provide for the "easy` fand free rotation of the grate.

.The grate 12 is provided with anannular gear-rack 23, andthe Vfire-chamber 11 is like-1 wise provided with aA correspondingannular gear-rack 24 in' vertical alinementl above? and vspacedfrorn the rack 23, so'that. one gear-A Y wheel 525,-suitably mounted lfor rotation upon a shaft 26 within the shell 10, will engage both racks, as indicated in'Figfs. 1'and`7.

A -The grate 12 will be formed with a central..

aperture 55,- beneath which a grate-'section 50 is slidably supported by ways or guides 51,v so that .a relatively large opening may-be,

jformed in the gratie to providemeans for the removal ofthe larger clinkers and to assist in controllingthe `lourning fuel.

The gear-wheel-25 will be supported-inV suitable standards 27 and provided exteriorlyfof fthe casingwith means 28 for the'attachment@ of an' operating handle or wrench, and when thus arranged it will loe vobvious vthat the rotation ofthefhandlecwill cause vthe corresponding rotation of the lire-chamher'and grate inppposite directions.

Y, 'Between the annular gear 24 anddthe'outer Vwall of the lire-chamber any annular track 29 isformed, the track providinga surface upon which cams. 31 act WhenTOtated to bodily'. elevate the fire-chamber and provide means for the removal of clinkers,A ashes, `and other forei ,mmatter and obstructions.

210 as shown, through. which their n parts may yhe reached and the clinlers removedvwhen the fire-chamber is elevated. A v j Thedoor32 will he provided with draftslides. 33 ,opposite vthe aShpit, as shown in Figs'and?. 1 f" I i The elevating-cams 3l Y l To this end aflarge door 32 is provided in the section I l TOO will preferably vhe located at Yequidistant. points upon opposite.

sides of the shell and far enough from the gear 25 to avoid interference therewith and will be supplied with sockets to receive operating-cranks, as shown.

The upper shell 14 is surmounted by'anvaln'- l nular top member 34, centrally from which a Between the shell 14 and magazine 35 is dis-l posed an annular hot-air drum 37, leaving annular air-spaces 38 39, respectively, between the shell and drum and between the drum and magazine, as shown.

The top member 34 is provided with a plurality of spaced apertures 40, and covering these apertures is an annular damper-plate 41, having apertures 42, adapted to register with the apertures 40 in the cover member when the annular plate is rotated in one direction andcut off the apertures when rotated in the opposite direction, the plate thus forming a cut-,off or damper to regulate the -flow of the air from the drum. The plate 41 may be operated by any suitable means, such as by a handle 43, extending from one side, as shown.

Leading inwardly through the upper sectionv 14 are tapered air-feed pipes 49 50, disposed at opposite sides and with their contracted inner ends or 'nozzles 51 52 turned downwardly and discharging in opposite directions above the fire in the {ire-receptacle, as shown in Figs. 1 and 3. By this simple means a supply of fresh air will be introduced in the form of jets moving in opposite directions above the center of the fire in the firechamber, and thus su pplying fresh oxygen where most required and greatly accelerate the combustion and completing the consumption of any particles of combustible matter which may escape the re in the body of the fire-chamber.

The pipes 49 50, passing above the fire in the fire-chamber, are highly heated thereby, and consequently highly heat the air passing through them and discharge it in a very highly-heated state and in the best possible condition to produce therequisite supplemental and accelerated combustion.

The tapered pipes 49 50 are very important features of the invention and add materially to the value and effectiveness of the operation. The outer or intake ends of the feed-pipes 49 50 will preferably be provided with closing dampers or slides 53 54 to regulate the iow therethrough. u

provided with a plurality of apertures 56 to provide vents for the escape of gas arising from the fuel in the magazine, which thus enters the air-space 39 and is drawn from thence downward into the fire and there consumed and prevented fromescaping into the room.

This is a very important feature of the invention and overcomes a very serious objection to many forms of magazine-stoves, as in many of these stoves gas accumulates in the magazines, especially if the fuel runs low, and escapes into the room. With the arrangement herein disclosed, however, all such accumulations of gas are readily disposed of and consumed and are thus not only prevented from l escaping into the room, but add to the heatimparting qualities of the stove.

Leading into the closed lower end of the drum 37 are cold-air ducts 44 45, the ducts eX- tending downward through the flanges 18 and 21 and the bottom of the ash-pit and opening near the iioor beneath the stove, as shown. As many of these airfducts may be employed as required; but generally two will be sulficient, as shown, to secure the necessary uniform distribution.

Above the shell 14 is a dome or top 46, from which the nal discharge-nue 47 leads, as shown, and supported above this liue is a fan-wheel 48 in position to be rapidly rotated by the rising currents of air and distribute them uniformly in all directions.

The fan-wheel 48 will be increased or decreased in size with the increase or decrease in the size of the stove or furnace and may be formed with as many wings or blades as required. The fan-wheel will also serve as an indicator of the action of stove or furnace, disclosing by its speedv the volume of the hot air rising through the discharge 47, as the greater the heat the greater will be the volume of air passing through.

The discharge-flue 47 may be conducted to any required distance and in any required direction and may be conducted to other rooms, if required, to supply the heated air to any number of rooms; but wherever and to whatever distance the flue may be conducted the fan member will be placed opposite the final outlet. By this arrangement it will be obvious that the heat rising from the air-drum 37 will highly heat the air therein and cause it to escape through the apertures 40 42 and through the dome 46 and discharge-flue 47 .to rotate the current-indicatingV fan-wheel 48, and this upward discharge of hot air will induce an upward flow of the cooler air from near the ioor into Vthe drum, and so on continuously, thoroughly and uniformly distrib uting the heated air and producing a uniform and equable temperature throughout the room or rooms of the building.

When it is desired to shake the grate, a few rapid revolutions of the crank 28 will thor- Near its upper end the magazine 35 will be oughly accomplish this result by rotating both the grate and fire-receptacle or basket in respectively opposite directions, which will produce a doubly efficacious result, thereby thoroughly and rapidly precipitating the ash es and clinkers and other unconsumed matter. 1f clinkers accumulate, they can be readily IOO IIO

removed, as above notedfby rotating the cams 31, and thereby elevating the basket, leaving a gap between its loweredge and the grate through which the clinkers and other accumulations may be readily removed.

The nozzle-pipes 4:9 50 are an important adjunct to the device, as they supply the fresh oxygen at the exact point required to produce the best results and edect a complete combustion of the unconsumed particles of carbon and eifectually prevent the formation of smoke or the escape of combustible gases, so' that nothing but a small amount of incombustible gases escape by the lues 16 or 17. The outer portions may be of any fanciful shape or design and ornamented in any desired manner, parts being nickel-plated or otherwise ornamented or protected.

When employed as a furnace, an outer shell or hood 55 will be employed, as in Fig. e, and when this is done the dome will be dispensed with, as shown; but otherwise there will be no change in the stove. By this means the stove may be set up in the basement or furnace-room and the usual conductor-fines connected therewith, the large volume ofV heat being ample to supply the fines, as will be obvious. doors corresponding to and located opposite the. doors and other openings in the stove, so

that the presence of the hood or shell does not interfere with the ordinary operations of the stove, and the operating-handles 28 will likewise pass outwardly through the outer shell.

The stoves may be manufactured in any size or ofV any suitable material y and may be eni-v ployed in all localities where other makes of stoves or furnaces are adapted to be employed.

If required, a vent-opening covered by a movable closure 56 may be arranged in the section 14 of the casing. By this simple arrangement it will be noted the fire-receptacle and grate can be very easily and quickly removed for renewal or repairs or another form of grate or hre-receptacle may be substituted for the one in the shell when the quality or kind of fuel is'to be changed. Thus the stove may be quickly and easily changed to adapt it to hard or soft coal or to coarse or fine coal, as required.. Thus by furnishing duplicate grates of different "mesh the same stove may be employed for all the different kinds and sizes of fuel. This is an important advantage and adds materially to the value and efliciency of the device.

The lower shell-section 10, together with the grate, lire-receptacle, and the Lnoze or lower discharge end of the magazine, will preferably be of cast-iron, while the upper shell-section, dome, and upper portion of the magazine will preferably be of sheet-steel of suficient gage7 to withstand the heat and other strains to which it will be subjected. The device can thus be very durably constructed and all the parts disposed to uniformly The shell 55 will be provided withV resist the strains to which they will be subjected.

The dome 46 will preferably be arranged to swing laterally, as by a pin 52, to expose the damper il and fuel-inlet 36, as shown.
