HOT-AIR STOVE.

PBCEFCATGN forming part of Letters Patent No.328,809, dated October 20, 1885. Application filed December 29, 1884. Serial No. 151,437. (No model.)

To @ZZ whom it may concern:

Be it known that I, RICHARD A. REW, a citizen of the United States, residing at Pomeroy, in the county of Garfield, Vashington Territory, haveinvented certain new and useful Improvements in HotAir Stoves, of which the following is a description.

Figure lis asectional elevation through the center of my improved stove, taken so as to show the openings and passages. Fig. 2 is a plan of the top of the stove. Fig. 3 is a sec tion through the top of the stove on the line a: x in Fig. l. of my stove to alarge hall or room. Fig. is a plan view of the same.

My invention relates to that class of stove used for heating rooms in dwelling-houses; and it consists in the detailed construction hereinafter more fully described, whereby a supply of cold pure air is taken into the stove, warmed to any desired temperature, and discharged into the apartment to be heated separately from the supply of air taken into the stove to support combustion, and so that the 'impure gases contained in the apartment shall be drawn into the stove with the latter supply of air and discharged up the stove-pipe, and thus keep the apartment thoroughly ventilated and filled with pure air of an agreeable temperature.

I will now proceed to describe my invention with reference to the accompanying drawings, in which similar letters ofreferencewhere used. in the different iigures indicate correj, spending parts.

A is the stove, provided with legs a, on which it stands, ring-door a, and stove-pipe ai, for removing the products of combustion.

B is a pipe supplying air to the grate in the stove. This pipe is carried down nearly to the floor of the apartment. All the air required to support combustion in the stove must pass through this pipe.

C is a second pipe connected to the inner casing surrounding` the stove and extending to the outside of the building or some other part of the same,where a supply of cold pure air can always be obtained, and provided with the damper o underneath the stove (see Fig. 4) for regulating the supply.

Fig. 4 shows the application AD is a hollow distributing-chamber,divided by radial partitions into communicating-see tions E and F,whereof sections E have openings e in the bottom of the plate, which communicate with the space e, between the middle and inner casings ot' the stove, and openings g on the top side of the plate, the use of which will be explained more fully hereinafter. The sections F have openings f in the bottom of the plate, which communicate with the space f between the outer casing and the middle casing of the stove.

G is the cover-plate, having openings goorresponding with the openings e in the top of the distributing-chamber, which is fastened in the top of the stove, while the cover-plate G can be turned around, so as to cover the holes e in section F of the distributing-chamber, more or less, as required.

Vhen the holes g are closed by the coverplate, the action of the stove is as follows: Pure cold air enters through the pipe C and is partly heated in its upward passage through the space e surrounding the stove. It then passes through openings einto the sections E of the distributing-chamber. From thence it passes into the sections F, through openingsf, and downward through the space f, between the inner and outer casings,and is discharged into the apartment around the bottom of space which is suiiiciently low down to cause the warm air to fill the whole of the room. The heat can be regulated by turning the coverplate G, when the openings g coincide with the openings,insectionsFofthedistributing-chamber, the heated air passing upward through these openings instead of passing downward through the space f, as indicated by the arrows in the drawings. All the impure air in the apartment, which has been breathed and contains carbonicacid gas, naturally gravitates to the floor and is removed from thence by the pipe B which supplies the air required for combustion to the grate,and is discharged together with the products of combustion up the stove-pipe a2. Foul air is thus constantly being removed and its place supplied with pure air obtained through the pipe C and warmed in its passage through the casings of the stove.

IOO

Vhen the apartment to be heated is very large, as in the case of a school or other public building, I sometimes prefer t0 carry the pipe B beloW the ii'oor and connect other pipes to it, which rise above the loor againin the corners or other convenient parts of the room, so as to collect the foul air from several points. rEhese pipes may advantageously have their ends Where they come above the floor made with small perforations, so as to decrease the liability of their becoming stopped up. I also sometimes prefer to carry the pipe G beneath the floor, as shown in Figs. 4 and 5, subdividing it into smaller branch pipes when the room is very large. These branch pipes I attach to channels j in the Walls at the back of the mopboards and provide a series of small holes, j', in the mop-boards, communieating between the air in the room and the said channels, so that the supply of cold air may be taken from various points and atV a sufficient distance above the perforated openings of the pipes which collect the foul air from the iioor of the room and convey it by the pipe B to the grate of the stove.

Having thus described my invention, What I claim and desire to secure by Letters Patent,

l. The combination of the cold-air-supplypipe C, distributing-chamber D, divided into communicating sections by radial partitions, and the stove A, provided With inner and outer casings forming the spaces e and f, substantially as and for the purpose herein described.

2. The combination of the cold-air-supply pipe C, distributingchamber D, having communicating sections or compartments E F, provided with openings ef, and the coverplate G, provided with the openings g, registering With the openings e', together With the inner and outer casings, substantially as described and shown, and for the purpose set forth. e

3. The combination of the cold-air-supply pipe C, distributing-chamber D, cover-plate G, the pipe B, for removing foul air, and the stove A, provided with inner and outer casings forming the spaces e and f, substantially as described and shown, and for the purpose set forth.
