Fig. 23shows the connections of the fences to the radial wings to form pens or yards for the animals, in communication with the stock receiving chambers.

Referring to the drawings by reference characters, the numeral 1 designates a sheet metal casing having a central tubular part 1 of a size adapted to slip over and receive a heating stove such as customarily used, which, being well known, is only conventionally illustrated.

Extending radially outward from the cylindrical portion 1 are a plurality of radial hollow partition and radiator members or wings 1 the hollow interiors B of which communicate with the stove chamber A and receive heated air therefrom.

The tubular portion 1 of the casing :forming the stove chamber A may be of any de sired shape such as cylindrical and may include arc shaped wall sections, but preferably, and as shown, the tubular portion 1: ispolygonal in shape and includes flat wall sections 1 alternating with open spaces l which communicate with the radial partition members or wings I p The radial partition members or wings flare outwardly at their outer ends. and form between them and the central tubular portion 1, stock enclosing chambers C which have restricted entrances thereto as indicated at d which are intended to be of such size that the young of the stock (for example small pigs) can find entrancetolthe stock chambers C while the full grown animals will be excluded therefrom.

Preferably, the casing is formed by readily attachable and detachable sections simple in design and few in number. Aplurality of stock chamber sections F are provided, each comprising a piece of sheet metal bent to form the back wall portion F which also forms the wall of the stove chamber A, and the adjoining flaring side wall portions F (Figs. 5 and 6). The stock chamber sections F are readily and detachably connected by stove bolts G or the like to radial wing de' tachable sheet metal sections H (Figs. 7 to 11), comprising the outer wall portion H and top portion H The sections F and H each are rovided with bottom or base flanges J to enable them to be secured to the floor. The outer wall portion H of the radial wing preferably constitutes a section separate from the top portion H and secured thereto by stove bolts G.

The connection between the sections F and H is established by providing an upstanding edge flange on the top section H and connecting this flange to the overlapping top edge of the section F by means of the stove bolts passing therethrough, as shown in Fig. 3. This upstanding flange on the top section H serves also to removably connect it with the top of the outer wall section H of the radial wing H in a similar manner by stove bolts G or the like.

The front edges of sections F join the side edges of the outer wall portions H by overlapping as shown in Fig. 4 and being secured by stove bolts.

so In the embodiment shown, there are five stock chamber sections F and five radial wing sections H (including top and outer wall sections H and H), which together make up the entire brooder casing, the radial wings being open from top to bottom at their inner ends Where they communicate with the stove chamber A. It will be understood that the number of radial wings may be varied by in creasing or decreasing without departing from the scope of the invention. Five wings provide a desirable arrangement, although a tactical embodiment may be produced havmg only three wings.

ie rods or braces K are preferably provided connecting the top of each radial wing with the adjoining one in order to give the brooder strength.

In the central outer wall of each section H and adjacent the bottom thereof are provided one or more cold air inlet apertures 'L, preferably two as shown. Further holes may ifdesired be provided in the angular-1y achommg outer wall portions, but are preterably shown.

The air enters through these apertures L and passes through the'radial wing into the stove chamber and is heated by the stove from which chamber itmay recirculate into the radial Wings again and heat side walls of the wings which are the side walls of the stock chambers and thus heat the chambers by radiation.

The inner wall F of each stock chamber section F is preferably provided according confined to the central outer wall, as

to the invention with an opening M providing direct communication between the stove chamber A and the stock chambers C. A portion of the air entering through the ports L and heated by the stove, passes directly from the stove chamber A to the stock chambers through the opening M. The opening BI is preferably located at a point nearer to the bottom of the wall F than to its top, so that the young stock will receive the full benefit of the heated air, which of course rises after being delivered to the stock chaniber.

A fixed or hinged deflector N is disposed above the opening M and serves to deflect the hot air in a downward direction toward the bottom of the stock chamber. This opening M permits the warm air to pass directly into the stock chamber from the heated .central chamber and does not interfere with the circulation of the hot air through the several radial wings. The deflector N and opening M may be formed by merely cutting a half circle or more in the sheet metal of the wall F and bending it out. This forms a per-- manent opening with a fixed deflector as shown in Figs. 3, 4, 5, 6, and 12. The fixed deflector may also be provided by securing a separate piece of sheet metal N at the top of the hole M by means of rivets or bolts 0 as shown in igs. 13 and 14. A further way of mounting the deflector is shown in Figs. 15 and 16, in which the deflector N is hinged above the opening M as shown at P and is held open by a wire or chain It having an end hooked over the top edge of wall F .By this arrangement, the direct-communication from the heating chamber to the stock chambers may be closed if and as desired.

Referring to Fig. 3, the arrows shoW the cold air entering the radial wing through the openings L and passing through the lower part of the radial wing and circulating through the heating chamber A and around the heating unit or stove. Some of the hot air passes back through the upper portion of theradial wing and heats the walls thereof being the walls of the stock enclosing cl1ambers and some of the hot ,air passes directly through the openings M into the stock chamher. This takes place in each radial wing and in each stock chamber as will be apparent. The arrows show the circulation of the air in a general way.

, Each radial wing may be provided, if desired, with an opening in the upper or top surface thereof as shown at S, which is provided with a closure member S and through which when opened more or less by regulation of the closure member, hot air may escape into the building in which the brooder is housed. This may be desired to enhance circulation or to provide heat to the room in which the brooder is housed, in addition to that passing out of the stock chambers.

The central chamber A is provided with a top closure indicated at a which is of general annular or ring form having a central opening 0 for the passage of a smoke pipe from the stove. The top closure member a is of a size to overlie and be supported bv the top of the tubular portion 1 of the brooder as shown at Z).

The closure member a' comprises a flat circular sheet of metal formed in two parts by being split diametrically and is hinged at 7 to be swung open when it is desired to refuel the stove. .The two halves preferably overlap slightly and the hinge f is formed by sim ply passing a bolt through the two halves at one end of the split. At the other end of the split, holes 9 may be provided in the overlapping section adapted to be aligned and to be held together by a suitable pin it passed through the holes, as shown in Fig. 3.

Fig. 19 shows the sheet metal cover a opened a short distance through its diameter. Then the cover a is opened, fuel may be fed into the store through the fuel feed door in the stove which is so disposed in the upper part of the stove as conventionally shown that it can be provided with fuel directly into the fire-box throu 'h the top of the heated chamber A. It will be apparent that for this purpose the split cover disc a may be opened fully so that the entire central portion of the heated chamber is uncovered, and may be closed to completely cover the said central port-ion of heated chamber A.

An oil burner may be used in place of the coal stove in which case the cover a as shown in Fig 20 will be provided with an opening is for the vent or smoke pipe of the burner and an opening is for supplying oil to the burner.

The back vertical wall portion F of the stock receiving section adjacent the ash pit of tie stove, where a coal stove is used, is provided near its lower endwith an openingh/ 3 adjacentthe ashpit for ash removal. Referring to Figs. 3, 17, and 18, this opening M has a closure member or door T. The door T is slidably mounted for vertical sliding movement with respect to the opening M to open or close the same. On either side of the opening guide plates T are secured to provide guide grooves T between them and the wall bounding the opening, for slidably receiving the door T. The door T is bent outward at its lower end to provide a deflector T so that when it is opened, the hot air will pass and be deflected into this stock chamber as it does into the others. Normally, the door T is not completely closed, but is left open or raised partially so that the hot air may pass into the stock chamber, although it may be closed entirely if desired. In removing ashes, the

door may be raised to provide adequate opening for this purpose. The door T proper is wider than the deflector T so that the sides can slip behind the plates and slide into the slots or grooves T and the deflector can move up and down between the guide plates T as the door ismoved. The ashes are read ily removed by an attendant who gets into the stock compartments, the compartments being intended to be large enough to accomplish this.

Fences U forming radial continuations of the radial wings are centrallv oinedthereto as shown in Fig. 23 and together with a generally circular or peripheral surrounding fence V form separate pens or yards W, with which the stock compartments communicate through openings (5, as shown.

The whole device including the heater, the brooder casing with its radial wings and stock chambers, and the pens or yards may be enclosed in a shelter house which as it forms no part of the present invention, is not shown herein. It will be apparent that instead of the surrounding fence V, the walls of the enclosing building may serve the same purpose.

As shown particularly in Figs. 21 and 22 a horizontal bathe plate X is preferably mounted in each radial wing under which it is intended that the cold or unheated air shall pass through the lower part of the radial wing in entering heated chamber A, and over which the heated air may re-circulate in the upper part of the radial wing. The baflie plate is not restrictive in this connection, since it terminates short of the outer end of the radial wing as shown at Y which of course permits commingling of the cold and heated air. The purpose of the baffle is to tend to direct in a general way the unheated air into contact with the heater and then in part back into the radial wing to heat the stock chamber walls. The baflle as shown is loosely supported near one end upon a rod X across the opening 1 and near the oppo site end uponpins or bolts X The bafile or partition X is disposed nearer to the bottom of the radial wing than to its top.
