rURNAoE 1 Application filed October 20,' 1921. `Serial No. 509,024.

. naces or Stoves, offwhich the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to furnaces or stoves of that class of the magazine type 1n which a large quantity o f fuel'lmaybe yplaced to be l gradually burned and `thus obviate the ney 'cessity of continuously supplying the lfurnace or stove withv fuel.

The primary objectief my invention is to provide a heating apparatus, either in the form of a furnace' or a stove, wherein the smoke and gases are led in proximity to the iire or live coals ofv the furnace oru stove to' be consumed thereby and increase the heatvheat radiating surface and'retard,'to a cering efficiency of the furnace or stove. l

Another object of 'my invention is to pro-` vide a furnace or stove with a large heat radiating` drum constructed to afford a large' tain extent, the exhaust gases of the furnace have cold air `directed lagainst the heating orstove so that the same may be burned and thus prevent products'of-combustion from being carried off in the nal exhaust of the furnace or stove.

As a furnace, the heating apparatus may be located in a furnace casing o'r shell and drum of the apparatus. VAs a stove, the heating drum is exposed'to the atmosphere to heat surrounding air, 'and in either instance a maximum heat is? produced by reason of all products of `combustion being consumed. Vith a good grade of fuelA there is very little residue and with avr low grade of fuel the same is burned until its full caloric value is obtained. l

The construction of my heating apparatus will be hereinafter described and then claimed, and reference will now be had4 to the drawing, wherein Figure 1 is a vertical cross sectional view of the stove, partly in elevation, showing by dot and dash lines vthe outline of a portion of a furnace shell in which the stove may be located;

Fig. 2 is a side elevation of the stove partly broken away and partly in section; and

Fig. 3 is aplanof the stove, on a smaller scale.

In the drawi1ig,-tliereferencelnumeral 1` denotes a substantially rectangular base which provides an ash chamber '2 either for the furnace or stove, and the-frontdw'all of `the base has a conventional form of afshvdoor 3 provided with `a'-daniper 4.,' .Thetop of the-`r base has an opening 5 for a rocker ort-iltable grate 6 which may be actuated-froin the n .e5 y

Between theupper end'S of the fire 'box 7 and the base'i there is asubstantially semi'- circular heat 'radiatingfdrum composed Aof -angularlydisposed'A parallel wallsv 18 and 19,

the wall 18 being integral with the upper end 8 of the fire box 7 and the wall 19intel gral with the lowerend'thereof;` both of said walls having curved outer flanged edges 20" connected by stove bolts 2 1 or other fasten- The'walls 18 and 19 therefore` cooperate in providing a combustionr cham-v ber 22 that is substantially semi-circular in i ing means.

plan and disposed at an acute angle to the base of the stove, the drum structure being somewhat as a skirt about the greater part of the fire box. v

Mounted in the upper end of the chamber 22 is a seinicircular baille or deflector'23 which is suported by inwardly projecting arms 24; mounted between or suitably attached to the flanged edges 2O of the walls 18 and 19. The wall 1S, intermediate its ends, has an exhaust stack or flue 25, which may be provided with a conventional form of damper (not shown Any suitable damper or damper operating mechanism may form part oit the furnace or stove in order that the operation ot' the urnace or stove may be conveniently controlled, but such damper or damperoperating mechanism forms no part oit the present invention.y

When a fire is started in the lire box 7 the live coals or fuel will be at the lower end or" the chamber 22 and such live coals will be exposed in said chamber and at the lower end of the passage 17, so that the down draft of smoke and gases must impinge against such live coals and be burned, if not actually consumed by the live coals. The downdra'tt of smolreand gases serves to protect the wall 18, at its juncture with the upper end 8 of the tire box 7, from being burned out or subjected to suchheat as may distort the wall 18, and such smoke and gases as is not consumed by the live coals ascends in the chamber 22, but is retarded in its ascension or passage through the chamber by the b aille 23.

By reference to Figs. 1 or 2, it will be noted that the edges of the baille 23 are in proximity to the walls 18 and 19 and for practical purposes the space between the edges of the baffle 23 and the walls 18 and` 19 should not be greater in area than the cross sectional area of the flue '25, so that there will be at all times an exit for the smoke and gases. However, the baille 23 will maintain somewhat of a circulation ot smoke and gases in the chamber 22 so that all products of combustion will be brought into intimate relation to the live coals to be consumed thereby. .ln this manner an intense heat will be produced at the bottom oi" the chamber 22, and as the live coal and products ot combustion are'consumed the coal within v the dome or magazine of the stove will feed downwardly and supply the nre-box 7.

The heatingapparatus has been illustrated as a stove in Fig. 2 and its use as a turnacc is suggested by the dot and dash line inclosure of' Fig. 1, it being understood that the door trames of the stove will be extended to meet the furnace casing so that fuel may be placed in the stove and ashes removed therefrom.

l attach considerable importance to the shape ot the heat' radiating` -drum as it affords a large heated area with which cold air may contact and be heatedy thereby, and urthermore, that with the stove in full operation it is practically impossible for combustible matter to escape from the stove without being burned. All of this contribyutes to the high heating etliciency of the apparatus, and while in the drawing there is illustrated a structure which has been put into practice, nevertheless, l do not care to contine my invention to any details other than defined by the appended claims.

`What l claim is 1. A magazine stove comprising a fire box having a substantially semi-circular heating radiating drum ormedby parallel walls disposed at an angle to the vertical axis of the sto ve, said tire box having an upper cylindrical end supported by one of the walls of said drum, an exhaust .tlue for said drum, a cover mounted on the cylindrical end ot said lire box and provided with an air inlet opening, and a dome suspended in said cover andhaving a doorway at said cover so that fuel may be placed in said dome, said dome cooperating with said cover in providing a passage opening into said drum, and said drum hav- `ing openingscommunicating with said pass ao'e.

t32. A magazine stove as called for in claim 1, and a semi-circular de'flector in the extreme outer portion of said drum forming a baille, particularly at the exhaust flue of said drum.

3. A magazine stove as called for in claim 1, wherein the air inlet opening of said cover is formed by an air intake member extending from 'the front of' said cover to the back thereof. v

ln testimony whereof .l a'liix my signature in presence of two witnesses.
