Application filed July 28,

In the artificial hatching of chickens a brooder is an essential adjunct and it is of vital importance that a device of this nature maintain an even temperature and insure a supply of fresh airwithout subjecting the chicks to air drafts which is detrimental.

The invention further aims to provide a brooder which admits of ready inspection of the brood and the admission of light and "which may be easily kept clean.

While the drawings illustrate a preferred embodiment of the invention, it is to be understood that in adapting the means tomeet specific needs and requirements the design may be varied and such other changes in the minor-details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and 'the-inerits thereof, reference is to be had to the followingdescription and the drawings hereto attached, in which,

Figure 1 is a perspective view of a brooder embodying the invention, provided with a roof when intended for out-door use.

Figure 2 is a vertical transverse section of the brooder, on the line 2--2 of Figure 3, looking rearward, as indicated by the arrows, the roof being omitted, and

Figure 3 is a vertical, central longitudinal sectional view of the brooder, the roof being omitted.

Corresponding and like parts are referred to in the followingdescription and designated in the several views ofthe drawings by like reference characters.

The brooder comprises similar upper and lower chambers 1 and 2 which, inthe preferable construction, are formed from sheet metal. These chambers 1 and 2 are of like dimensions and are placed one upon the other and are hingedly connected, as indicated at 3, whereby the upper chamber 1 may be raised when required. her 2 is preferably open at the bottom and top and is provided in its back Wall with an opening to which is fitted a door 4, the same being hinged at itstop to normally maintain a closed position. A lamp 5 is located in the chamber 2 and is removable through the opening closed by means of the door 4. The part 2 constitutes the heatlng chamber in contradistinction to the part 1 which forms the brood chamber.

The lower cham- 1926. Serial No. 125,499.

The brood chamber 1 is closed by a bottom 6 which is preferably of sheet metal and in the center of which'isformed an opening 7 A top 8 extends over the chamber l'andis tends from the top thereof through the top 8. The hot air andgases from the lamp5 pass from the heating chamber 2 through the opening 7 into the drum 11, thence through the vent pipe 12 into the atmosphere. it plate 13 connected to the bottom 6 and spaced therefrom acts as a spreader and the hot air and gases striking the lower side of the plate 13 are deflected laterally in all directions and pass around the outer edges of the plate,-thence along the top side of the plate 13 and out through the opening 7. In this manner the bottom 6 of the brood chamber 1 is heated throughout its extent. Bolts 14 connect the spreader plate 13 to the bottom 6 and spacers mounted upon the bolts 14 maintain the plate 13 a fixed distance from the bottom 6. A bed 16 of sand or other suitable granular material is placed upon the bottom 6 to any desired depth and this bed surrounds the lower portion of the.

drum 11 andoperates to uniformly distribute the heat. At state-d intervals the top portion of the bed 16 may be removed and if desired may be replaced by alike amount of fresh material. In this way the brooder 1S rendered sanitary and may be easily kept clean.

When the brooder is located out doors it is provided with a roof 17 to shed rain and to attord-protection. The roof 17 is provided with depending straps 18 adapted to engage loops 19 upon the outer side of the brood chamber, pins 20 passing through the parts to retain the roof in place. Obviously, when the brooder is located indoors the roof 17 is not necessary and is dispensed with. A runway 21 extends from the bottom of the brood chamber 1 to the ground and is provided upon its top side with cleats or lags to enable the chicks'to obtain a sure footing'both when leaving and entering the brooder. A door 22 closes an opening in the lower portion of the front of the brood chamber and is hinged at the top to normally maintain a closed position and is free without hindrance-Q The brooder may be used'with equal advantage .in-doors or out-doors but when arranged in the open, it isessential that the roof 17 may be employed. The brood chamher is maintainedatthe required temperature by proper-adjustment of thelamp 5, said temperature beingascertained in'the usual -wayby means of a thermometer, not shown, associated with the device. [Access chicks may enter or leave the brood chamber to the lamp..5 is readilylhad through the openingclosed by the door 4. iThebrood maybe inspected byopening the top 8 and when sunshine is to be admitted into the brood chamber the-top ,&may be propped open -as will be readily understood; The drum 11 may be connected to the bottom 6 in vany preferred way, asby beingsoldered thereto. The brood'chambermaybe readily cleaned by opening the top8 and swinging said chamber upon-the hinges 73 whereby to discharge the material forming the bed 16. -H.aving thus describedthe invention, we claim:

A broodercomprising separable upper and lower chambers a heater in the lower chamber, the upper chamber having a bottom which extends over and closes the top of the lower chamber and saidbottom havto swing inwardly and outwardly so that the ing a centrally disposed opening, a plate attached to the bottom of the upper chamber and spaced therefrom,-=and terminatingatits edges a short distance from the enclosing Walls of the lower chamber and a drum supported upon thebottom of the upper chamer in line with the opening therein and having a vent pipe extendingfrom the top ghereof throught-he top of the-upper cham- 2. A broodercomprising separablevupper and lower chambers, the upper chamber having a bottom extending over and closing. the top ofzthelower chamber, and formed with anropenl-ng, aheater 1n the lowerrcha-mber,

grannlarbed placed upon the. bottom ofthe upper chamber and a drum having its lower end passing through the .sa1d granular1bed and supported upon the bottom of theupper chamber in line with theopening therein and having awentpipe extendingtherefrom through V the top of-the chamber.

In testimony whereof we aflix our signa- V ,tures.
