ion relates to an improvement This invent in stoves.

The object of the invention is to provide a stove in the nature of a 'coal burning stove, or one for burning solid fuel, of an improved construction which will produce an even burnin of fuel within a fire-pot without the possibi 'ty of the coal caking and sealing up around the edges as it does in the ordinary form of coal stove. The invention is especially designed for use in connection with brooders, although it is not limited especially to this purpose.

The invention consists more especially in the construction of the stove and the many novel features involved and incorporated therein. A humidifying pan is provided upon the stove support and beneath the stove and is provided with openings on all four sides for better diffusion.

The shaker-grate is mounted on ball bearings to facilitate ease in operation thereof, and the construction of the grate allows the removal of clinkers merely by withdrawing the shaker and moving it relative to the grate. A preheated draft intake is arranged at the bottom of the stove to supply air and a draft thereto, and combined with this is a cold air regulator arran ed at the top of the stove d air thereto. A removable her and smoke-stack for forcing the cold air into the combustion area before its escape up the chimney.- This bafiie plate allows the a smoke to be discharged from the center of the stove instead of from its edge, as in the ordinary stoves ofthis character, which center outlet encoura es the fire to burn out in the center of the re-pot as well as the outside walls, giving a steady heat. The bafie plate is provided. with sloping back edges to allow the soot to slideout of the way of the passing smoke; l The interior of the fire-pot is corrugated and a plurality of vertical fins are formed on the exterior of this fire-pot, these fins and.

corrugations being parallel and corresponding to each other, so that the path of the circulating air is not affected, the air simply passing upward between and for the entire length of the fins in direct contact therewith, WhlCh fins form Vertical flues for directing the air in a circulating path up along the surface of the stove, preventing any heat eddies. Both sides of the flanges are equally effective.

When the vertical flanged fire-pot desires to expand, 1t is perfectly free to do so, and there are no lateral restraints tending to cause a cracking of the fire-pot, as might occur and often would if the fins were arranged circumferentially of the fire-pot. The fire-pot tapers from 1ts bottom to top, "and this taper, together w th the parallel interior corrugations and outside fins, prevents any sealing over on the lnslde of the stoveby the settling of the coal s. The walls arethus made thinner, which decreases the cost of manufacture, and hkewlse of shipping by reason of the lighter Weight of the stove, and on the other hand provides a greater radiation of heat by reason of the thinner walls.

The stove shown in Fi 1 is mounted upon a support 1 provided with upstanding lugs 2 upon which is seated the base 3 of the stove, as clearly shown in Fig. 1. The back lugs 2 are connected together by a stop 4 at the back edge of the support 1. A humidifying pan 5 is mounted upon the support 1, its backward movement being limited by a stop 4 extending across thebase, as shown in Fig. 1. This humidifying pan immediately beneath the stove,

and is I open 5is thus mounted loov v on all four sides thereof to supply humidity out portions 10, which are seated upon the ball bearings 8 for supporting the grate. This grate is provided with a central opening 11 and integral lugs 12 extending inwardly toward each other below the grate 9, as shown in Fig. 1, to receive and supporta shaker 13.

An integral depending lu 14 extends downwardly from the front edge of the grate 9 and when the shaker is in position upon the lugs 12, the lug 14 extends into a longitudinal slot 15 in order to limit sliding movement of the shaker in both directions. Both the grate and the shaker are provided with a plurality of small holes therethrough to allow the ashes to sift down from the body portion of the stove. In order to shake the grate, the shaker 13 is moved back and forth, which gives the grate an oscillatory movement upon the ball bearings 8, causing the ashes to sift down through the openings in the grate and shaker. The shaker 13 is slidably mounted on the lugs 12 and may be pulled out, its outward movement being limited' by the lug 14; to allow any clinkers or cinders to drop down through the central hole 11 in the grate 9 and through a notch 16 formed in the end of the shaker 13, as

. shown in Fig. 8, which notch registers with the central opening 11 to allow the clinkers or cinders to drop from the interior of the stove. This makes it unnecessary to cool off the stove or to remove the grate in order to extract clinkers which may get into 1t and oft-times hinder the successful operation of the stove.

A rib 17 extends upwardly from the base 3 and a fire-pot 18 fits within the rib 17 and 1s mounted upon an inturned'flange 19 carried by the base, which flange also supports the projections 6 which contain the ball bearings 8 for supporting the grate.

The interior of the fire-pot 18 is corrugated as at 19, as shown in Figs. 1 and 5, and extending parallel with these corrugations 19 are exterior fins 20, which extend vertically along and are integral with the fire-pot 18. These fins form vertical flues along the outside of the fire-pot. in order to direct the air upward along the stove and, in contact therewith and which produces the greatest possible radiation. The fire-pot is larger at the bottom than at the top with the general tapering to the latter so that the coal burns and settles down through the grate with no possibility of its caking or sealing up air-tight around the edges. This is also facilitated by the corrugated interior. It will be noted especially in Fig. 5 that the corrugations 19 which extend parallel with the fins'20 reduce the amount of material in the walls of the fire-pot to a minimum, thus decreasingv the cost of manufacture and likewise of shipping by the decrease in weight and material. These thinner walls also provide greater heat radiation. The thickness of the metal is substantially the same at all points, which lessens the tendency toward cracking of the firepot, due to unequal expansion of the metal. The construction of thisfire-pot is an important feature of this invention.

A head 21 is secured upon and supported by the fire-pot 18 and this head is provided with an inturned flange 22 upon which is seated a baflie plate 231 This baflie plate 23 is removable and seated between the lugs 24, which hold it in its proper position with the head 21. An upstanding flangs 25 co-oper-' ates with a depending flange 26 on the top 27, which is seated over the head 20 to divide the back portion of the top into-compartments, which communicate with the interior of the fire-pot over the front edge of the removable baiiie plate 23. A damper 28 is carried by brackets 29 for regulating the supply of air into the air chamber 30 on one side of the flanges 25 and 26. A smoke chamber 31 is provided on the opposite side of these flanges and is open at its top to allow the dis-" charge of smoke through a suitable pipe connected with the flange 32 formed upon the top 27. A flange 33 is also formed at the front side of the smoke chamber 31 in order to limit the communication of the smoke chamber with the interior of the fire-pot to the center thereof, so as to promote the natural draft through the center of the stove instead of only at its outer edges as in most stoves of this character. v

The feed door 34 is connected with the top 27 to allow the admission of fuel into the fire pot 18 and this doorextends entirely across the top 27 in order that a coal scuttle may be inserted thereinto, thus preventing spilling of any coal as it is admitted to or inserted into the stove as so often happens.

A preheated air intake tube 35 is secured to the side of the fire-pot 18 and communicates at its lower end withthe opening 36 into the base 3for preheating the air or draft through the tube 35 and this draft control 37 is automatically actuated by any suitable form of thermostatic device, designated generally by the numeral 38, as shown in Fig. 6, and is connected with the damper 28 by means of a flexible connecting wire 39, which simultaneously actuates the draft control and dam er, opening the one upon the closing of the ot er.

It will thus be seen that a coal stove is rovided of an improved construction, whic is especially designed for use in connection with chicken brooders, and by reason of its many superior and novel features, it is a great imtical corrugations formed in the interior surface thereof and having exterior vertical fins formed upon the outer surface thereof and parallel with the interior corrugations to provide the walls ofthe fire-pot of approximately uniform thickness and to form approximately vertical air flues about-the exterior ofthe fire-pot to increase the radiation of heat therefrom and to conduct the air into contact with approximately the entire exterior surface of the fire-pot.
