To all whom t may concern:

Be it known that l, WILLIAM D. FRAZER, a citizen of the United States, residing at Dain, in the county of Nicholas and State of West Virginia, have invented certain new tus, and more particularly to a stove or heater of such construction that a number i of stoves may be connected together so that the products of combustion from one st ove will pass into the next succeeding stove and so on to the point of final discharge, each stove being adapted, however, to be used separately from the other stoves.

The primary object ofthe invention is to 'construct a stove of the character described which may have a fire built in it and be used in the ordinary or usual manner, but.

that the products of combustion from a stove on the floor below may be passed through it either directly or by a circuitous course.

A further object of the invention is to provide a stove of the construction described with an entirely rotatable grate, this grate carrying a back wall which may be rotated either -to the front of the fire space or charnber or to the rear thereoff Still another object of the invention is to provide means whereby'fresh air may be taken into the ash pit beneath the grate and the products ofcombustion carried directly up out through a flue, whereby products of combustion from a stove below may be directed either beneath the grate of the firstnamed stove and then directly out through the flue, or beneath thev grate and by `a circuitous course around a heating chamber and out through the flue, or whereby the products may be directed upward at the back of the stove without passing through the grate thereof and so out through the flue. J

Other objects of myinvention are to im? prove on the detailed construction of stoves of this character whereby they may be cheaply made and readily installed.

My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical longitudinal section of a stove constructed 1n accordance with my invention; Fig. 2 is a vertical section on the line 2-2 of Fig. 1; Fig. 3 a horizontal section on the line 3*?) of Fig. 1; Fig. is a section on the line ele-4 of Fig. 1;) Fig. 5 is a diagrammatic view showing how my improved stoves are arranged in houses; Fig. 6 is a vertical sectional view on the same line as Fig. 2 but showing a water reservoir disposed within the heating chamber 27.

I will first describe one of my improved stovesas illustrated in Figs. 1 to 4. rlhis stove consists of the body 2'which is preferably of sheet iron and preferably elliptical in plan. This body is formed with the top 3 and the bottom 4. The front of the body has the usual fire door 5, and disposed around the body just below the fire door is the main frame casting 6 which has preferf ably an upwardly extending flange 7 whereby it is rivetedto the body 2 or otherwise attached thereto. This main frame casting, as shown in Fig. 3, is cut away at its forward end' to provide a grate opening 8 and at its rear end to provide a draft opening 9 and atv its middle as at 10, there beinga Sheet metal plate 11 fitted over this opening 10 so as to lighten the weight of the casting as y much as possible. The middle of the casting 1s supported upon a transversely extending arch wall 12 which Iis bolted or otherwise attached to the side of the body, the casting 6 having downwardly extending flanges 13 engaging over the upper edge of the arched f wall and assisting it in holding it in place.

It will be noted that the casting 6 constitutes a. septum' dividing the upper portion of the stove from the lower portion. Rotatably mounted in the grate opening 8v is the grate 14 which may be of any suitable form but which is preferably a .rotatable grate formed uponits lower face with the annular rack 15.

This rack is engaged by a vgear wheel 16 carried upon a short shaft 17 whichextendsout at the front of the main casting and to which a crank is adapted to be applied. De-

tachably mounted upon this rotatable grate is the semi-cylindrical back wall 18 having the form of half of a iire pot. Mounted in the opening 9 is a damper 19 which is pivotally supported in any suitable manner and is preferably mounted upon a pintle 20. which eXtendslout through the side wall of the body so that the damper may be rotated either to an open or a closed position.

' stove on the lower floor.

v wall 18 extends upward approximately to` the top of the heating chamber 27 and thatA The bottom 4 of the stove is formed with an opening 21 and depending from the'bottom ofthe stove around this opening is -the flue section 22 which is adapted to be connected to a flue section extending from a Disposed in this flue section 22 is a damper 23 whereby passage through thisv Hue section may bey controlled, this damper being mounted upon a pintle 24 which extends out to the front ofA the stove and is-provided with a handle 25 whereby it may be manipulated and the damper closed or opened or otherwise regulated. Disposed in theft'op 3 of the stove andin vertical alinement with the flue sec-- tion 22 is a 'lue section 26 which is adapted to be connected-with a lue leading up to a stove on the floor ,above or to the chimney of the house.

Disposed within the body 2 and extending transversely across it is a heating chamber 27 which preferably opens at the sides of the stove and is provided with suitable doors. This heating chamber may be either yused, for cooking or for the Aheating of water. Thus it may be used either as am oven or as a water back, as desired. Extending downward from the top 3 to the top wall of the chamber 27 is a vertical wall or' partitionl 28 formed with an opening 29, passage through which is controlled by a damper 30. .It will be seen that the back when the back wall 18 is in its rearward position it is spaced a relatively slight amount lf)rom7the front wall vof the heating cham- In Fig. 5 I show how a plurality of stoves, each disposed on one floor of thev house, may be connected to each other so that the products of combustion from a lower stove will pass upward and through an upper stove. vThe several stoves are desiganated respectively 2, 2b and 2. The flue connectlng the several stove's is designated 31,

and the final discharge flue is 'designated 32. In practical use any one LorV more of the stoves may be`fired. When. the fire is built in any one of the stoves its fire pot wall 18 is turned to the rearward position and a damper 33 in the door of the ash pit below7 the grate 15 may be opened to permit thelowed to pass up through the flue section 22 and -will then be deflected into the ash pit and pass up through the grate. The damper l30 is of course openedso as to allow the 4 products of combustion to pass from the fire space up the flue 26. If it is not desired to draw vair from the stove below, the damper -22 is closed. The stove will then act in all no fire in any of the upper stoves and it is not desired that the products of combustion from the lower stove shall be used to heat the upper lo'ors of the house, then the dampers 23 of the7 stoves are opened, the dampers 19 of the upper stoves are opened, and the dampers 30 of the upper stove are closed. Under these circumstances the products of combustion will pass directly up from the lower stoves through the rear portion of the .upper stoves and out through the Iinal discharge flue. If on the other hand itis desired to utilize the heat escaping from the lower stove 'in the upper stove the damper 12 of the upper stoves is .closed and the products ofl combustion from lthe lower stoves are directed laterally into the ash pit or boxbeneath the' grate, then up through the grate and then out through the iue 26 by way of the opening 27. If it is desired to utilize this heat for the purpose of heating the cha'mber 27 then the damper 30 in the upper stove is closed andthe heat as a consequence will pass up over the back Wall or fire pot wall'18 anddown in front of the chamber 27, then along the bottom of the chamber vand then up and out through the flue section 26. Thus the heat is caused to take a circuitous course and heat the contents of the chamber 27. It will of course be understood that heat from a lower stove may also be passed into an upper stove when there is a fire burning in theupper stove and that this heat may be directed either up through the rear portion of the upper stove or up through the re in the upper stove.

It will be obvious that by rotating the grate 14 the back wall 18 may be carried 'around toward the front of the stove,`.thus

tending to prevent the radiation of heat from the front of the stove' but providing for the passage of heat upward through the opening 9 and around on all sides of the heating chamber 27. When turned in the position shown` in Fig. 1, however, this fire back permits the building of a fire upon the grates 14 and acts to radiate the heat outward and forward.

My improved stove construction provides means whereby heat which would be other- -wise wasted may be conserved, and I have found in actual practice that Yunder most circumstances enough heat will be secured from a lower stove or stoves to heat the upper floors of a house. Furthermore, itwill I be obvious that a stove may be so controlled as to apply this heat to the best advantage and that the stove may carry its own fire `but heated by heat passing upward from a stove below orutilize both the 'heat of its i own re and the escaping heat of the stove below. The chamber 27 may be usedffor baking purposes or as a means of water heating, it being obvious that a water heater may be inserted within this `chamber and operatively connected to the pipes of the house. A'water heater itself may be disposed in place of this chamber, in other words, a structure composed of water coils, and I regard this as entirely within the purpose of my invention. I have illustrated in dotted lines a series of water coils disposed in the space occupied by the. chamber 27,

and in Fig. 6 I have illustrated Ja water resbelow and so eventually'into the cellar or other collecting place for ashes into which the opening 21 of the lowermost stove will discharge. This may be readily accomplished with the stove illustrated in Fig. 1 by opening the dampers 23 and 20 of the lower stoves and opening the damper 23 of the uppermost stove and then pushing the ashes collected in the ash pit back under the 'supporting arch or bridge 12 to the opening 21. By this means there will be no necessity of collecting ashes from the stoves on the upper floors of a house, but all the ashes may be gathered from the stove .on the lower floor or from an ash pit in the cellar.

Having thus described the invention, what is claimed is: l

1. A stove of thel character described having a fuel supporting grate, an outlet flue section in its bottom and an inlet flue sectionY in the top rearward of the grate and in ap- .proximate alinement whereby products of combustion from another heating appliance may be passed upward through the rear ofthe stove, means for controllably admitting fresh air beneath the grate, a heating chamber disposed rearward of the grate, and means for directing. all products of combustion entering through the inlet flue either directly upward through the stove rearward of the heating chamber, forward, beneath and through the grate and over the heat-ing chamber and to the outlet flue, orI upward through the grate, then downward and rearward beneath the heating chamber and then upward through the outlet flue.
