BROUDEB.

Application filed January 12, was. Serial no. mazes.

To all whom it may concern:

Be it known that 1, JOHN S. MACKENZIE,

a citizen of the United States, residing at Delaware, in the county of Delaware and State of Ohio, have invented certain new and useful Improvements in Brooders, of which the following is a specification.

The present invention is directed to improvements in brooders, and has for its 0 primary object to provide a brooder so constructed that it can be placed in a room or the like, the heat therefrom keeping the room at the desired temperature, and at the same time permitting the chicks to congregate under the heat deflecting canopy at points desired for individual chicks. It is a well known fact that strong chicks require less heat than theweaker ones, thereby by the presence of the heat deflecting canopy the weaker chicks can remain thereunder while the stronger ones may seek cooler areas. I

A further object of the invention is to provide a brooder having a novel form of heater being so constructed that the heat will be deflected in such manner as to be trapped evenly under the canopy and directed downwardly upon the backs of the chicks under the canopy.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of: construction, combinations of elements and arrangements of parts, and hereinafter to be fully described and pointed out in the appended claim.

In the accompanying drawing:

Figure 1 is a side elevation of the heater, the canopy being shown in section, and

Figure 2 is a vertical central sectional view, on enlarged scale, of the heater and canopy.

The brooder comprises abase 1 in which is supported the oil font 2 of the associated burner 3, which maybe of any approved wick type, the wick being adjustable through the medium of the rod 4, as is usual.

The base 1 has hingedly connected thereto, as at 5, a burner chamber 6, to the upper end of which is secured the lower end of the conical wall 7, to the upper edge of which is secured the lower edge of the conical wall 8, said walls providing .a heating chamber 9. Located in this chamber are annularly spaced brackets 10 to which are secured the periphery of the inverted conical heat deflector 11, the brackets being of such size as to hold the periphery of the deflector spaced from the meeting ends of the walls '7 and 8 formed in the chamber 9, whereby an annular heat passage 12 is provided. The vertex of the wall 8 is provided with a heat outlet opening 13, and associated therewith is a chimney 14: to permit the defiectedheat to escape into the room in which the brooder is located.

The canopy 15 is formed from galvanized sheet metal and is of conical formation, and has its vertex provided with an opening 16 for detachably engaging the chimney 1% so that said canopy can be conveniently lifted from the burner when desired. I

The canopy is lined with asbestos sheets 17 which are retained in place by the lining 18 of sheet tin. Fixed interiorly of the canopy is a plurality of cleats 19 which are adapted to rest upon the wall 8 and hold the canopy spaced therefrom to provide a heat retaining chamber 20. To permit the canopy to be conveniently handled the same is provided with a pair of handles 21, and

further with a swinging door 22 which normally closes the hand opening 23, said hand opening serving to permit access to be had to the wick controlling rod 4 so that the. A

burner can be conveniently regulated without stopping to remove the canopy.

From the foregoing description it will be apparent that the heat from the burner will be deflected by the deflector 11 consequently evenly heating the walls 7 and 8, the heat radiated therefrom being deflected by the canopy downwardly and upon the backs of the chicks immediately thereunder. Owing to the presence of the chamber 20 heat re vide a relatively large heating chamber, an inverted conical reflector supported in the heating chamber and having its periphery spaced from the sides thereof, a heating element located in the base for furnishing heat to the heatingchamber, a canopy removably supported by and spaced from the heating chamber and confining the same to provide a heat retaining chamber above the heating chamber, the lower end of said canopy be 10 ing disposed below the heating chamber.

In testimony whereof I afiix mysignature.

JOHN S. MACKENZIE.
