HEATING-STOVE.

Application filed July 14,

T 0 all whom it may concern Be it known that I, RowLnY RonINsoN, a citizen of the United States, and a resident of Camas, in the county of Clark and the State of VVashing-ton, have invented a new and useful Improvement in Irleatingfitoves, of which the following is a specification.

My invention relates to improvements in stoves such as are used for heating air, either as a stove to be located in the room to be heated or as a so-called hot-air furnace such as are used for heating air which is later circulated t0 the room or rooms where needed. The object of my improvement is to 111- crease the effectiveness of the heating surface of the stove and so improve its efficiency.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a stove or heater constructed in accordance with my invention;

Fig. 2 is a longitudinal vertical sectional view thereof;

Fig. 3 is an enlarged fragmentary vertical sectional view through one of the radiation drums or casings;

In these drawings, I have illustrated a combinated cook stove and heating stove, and in this construction I have embodied a longitudinally extending, hollow body 10, from one end of which there extends upward a casing or drum 11, within which is disposed a grate 12 and an ash pan 13, the grate 12 being at the bottom of the fire pct 14. The front wall 15 of this casing or drum is provided with an opening to the fire pot and an opening to the ash pit from which the ash pan may be withdrawn, these openings being closed respectively by a door 16 and by the end 17 of the ash pan. A damper 18 is disposed below the grate 12 whereby air may be admitted to the grate. The top of the drum 11 is formed with openings closed by stove lids 19. Extending upward from the body 10 at a plurality of spaced distances and opening at the lower ends into the body 10 and practically forming part thereof are the radiation drums 20. Extending upward from the bottom of the body 10 and into each radiation drum and spaced from the side walls thereof are the baflie plates or webs 21 so disposed that they cause the hot gases and products of combustion passing from the fire box to pass up ward into each of the radiation drums sue Specification of Letters Patent.

cessively and then downward into the body and then into the next radiation drum. The end wall of the stove is provided with the large outwardly projecting collar 22 whereby a pipe may be connected to the stove.

It will be noted that the fire pot 14 is spaced from the outer wall of the drum 11 so as to leave a passageway l1 leading into the body below the ash pit and that from thence the products of combustion pass along successively through the several chambers or radiation drums 20 until they pass out through the flue collar 22.

While I have illustrated two drums 20 and one drum 11., I do not wish to be limited to the number of drums 20 which may be used, as the number of these drums is limited by the size of the stove and the heat desired. Neither do I wish to be limited to the positioning of the heating drum 11 at one end of the stove, though this is preferable. It will be seen that the partitions or baffles 21 and the fire pot 1a are so arranged as to cause the products of combustion to take a circuitous course in passing through the stove so that a large part of the heat is radiated into the room from the several drums 20 before the products of combustion pass out through the flue. It is further to be noted that by arranging the drums 20 in spaced relation to each other, spaces 20 are left between the several drums 11 and 20, by which the air in the room is brought in close contiguity with the heated drums. Of course, the draft is to be regulated in the usual manner by the damper 18 and by a damper in the stove pipe (not shown).

While I have illustrated this device as forming a combined cook stove and heating stove, yet I do not wish to be limited to this, though I regard it as preferable, as a stove to be used entirely for heating might be constructed upon the same principal or it may be used as a so-called hot air furnace.

In order to provide means whereby the draft may be increased while starting a fire, I have illustrated the baffles 21 as being vertically movable from a position on the floor of the stove to a raised position from the floor so that the products of combustion may pass directly from the heating drum 11 to the flue. This permits one or more of these bafiies to be raised to thereby control the draft when the fire is started. It also permits these bafiies to be raised so as to permit the body to be cleaned out. To this end, I

mount each baflie in its corresponding radiation drum between inwardly projecting lugs or other guides 23 which may be riveted to the end walls of each radiation chamber, and I attach to each baffie plate an upwardly extending rod 24: extending out through the top of the radiation chamber and having a handle whereby the battle may be raised or lowered. Preferably these rods 24 extend out through tubular guides 25 attached to the upper face of the radiation chamber, which guides may have asbestos packing therein to prevent the escape of combustion gases and these guides carry means, as for instance an ordinary'latching device, 26 embodying a clamp by which the rods 2% may beheld in any adjusted position. Of course,

I do not wish to belimited to the details 01- being formed with a plurality of upwardly extending, radiation drums opening into the body and spaced fronreach other whereby air may-pass between the drums, and bafile partitions extending upward from the bot torn oi the body into said radiation drums and nearly to the upper ends thereof whereby to cause the products of combustion to pass successively through the several drums, said bailles being vertically shil'table independently of each other.

2. A heating stove or furnace comprising a body formed with a plurality of outwardly extending radiation drums opening into the body and spaced from each other whereby air may pass between and around the drums, the body having an inlet at one end and an outlet at the other end, and bafile partitions extending from the outer wall o1" the body into said radiation drums nearly to the outer ends thereoi, whereby to. cause the products of combustion to pass successively through the several drums, said'ballie partitions being longitudinally shiftable Within the drums in each other.
