Claims.

5 wood heater having means to automatically regulate the draft of the heater whereby the desired temperature can at all times be maintained in the brooder.

Another object of my invention is to provide an attachment of this character which can be readily applied to the ordinary down draft heater without altering the construction of the heater in any way and which has the same operation and advantage as a brooder having a specially constructed heater.

A further object of my invention is to provide an attachment of this character in which the automatic control of the damper is so positioned it will not be affected by the direct heat from the heater and in which the automatic control can be regulated to the desired temperature.

A still further object of my invention is to provide a simple, cheap and effective brooder attachment for wood heaters having certain details of structure and combination of parts hereinafter more fully described.

In the accompanying drawings:

Figure 1 is a side elevation of an ordinary down draft wood heater with my attachment applied, forming a complete automatically controlled brooder.

Figure 2 is a, top plan view of Figure 1.

Figure 3 is a vertical transverse sectional view taken on the line 33 of Figure 1.

Figure 4 is a vertical sectional view taken on the line 44 of Figure 3 at right angles to Figure 3 and looking in the direction of the arrow.

Figure 5 is a vertical sectional viewof a modified form of the down draft pipe.

Figure 6 is an enlarged perspective view of the base attaching means.

Referring now to the drawings:-

l represents the ordinarydown draft wood heater having the down draft pipe 2 extending upwardly close to the body of the heater to a point adjacent its upper end. These heaters are mounted on legs and the upper end of the body is provided with a cover 3 by means of which the wood is fed to the stove. The heater is also provided with the usual stove pipe 3' extending from the upper end, but this stove pipe could extend from the side of the heater. The upper end of the down draft 2 is provided with the ordinary hand operated shutter damper, as is well understood by those skilled in the art. My improved brooder attachment comprises a circular band 4 of flexible sheet metal provided with a series of openings 5 to allow the air to circulate under the body of the heater. This band is provided on its inner face with inwardly extending 5 lugs 6 adapted to be sprung into the socket from which the ordinary legs of the heater have been removed. By this structure it will be seen that the small chickens cannot get under the stove or crowd each other due to the fact that the same 10 is of a circular form. The hood 8, forming the top of the brooder, is composed of a conical circular ringhaving the opening 9 therein of a size to closely fit the outer wall of the body I of the heater and is supported by means of legs Ill so that its lower edge is supported a distance from the floor so that the chickens can readily pass under the same. In order that this hood may be readily slipped down over the heater, it is provided at one side with a cut away portion ll of a size slightly greater than the down draft pipe 2 and the thermostatic control damper carrying housing l2, as clearly shown in Figures 2 and 4. By this structure it will be seen that the hood 8 can be slipped down around the stove until the legs I0 rest upon the floor. 'In order to make a tight fit around the down draft pipe 2 and completely close the opening ll, after the hood has passed the automatic damper control housing I2, I provide two sheet metal plates l4 and I5 pivoted at l6 to the hood 8 and having their inner edges I1 and I8 arranged in an arc or circle to correspond with the body of the heater 1 In beyond these curved edges, the plates are provided with cut away 35 portions l9 and 20 adapted to correspond with the curve of the down draft pipe 2 and whereby the plates l4 and I5 are moved inwardly and a tight fit is made with the body of the stove and the down draft pipe to retain the heat under the hood. In order to hold the plates in the operative position, I provided buttons 2| and 22 which are adapted to be turned over the edges of the plates I4 and I5 to hold them in their operative position. 45

The ordinary wood heater of this type, as heretofore stated, is provided with a hand operated damper at the upper end of the down draft pipe. This damper is in the form of a cap efiect extending around the upper end of the down draft pipe and bolted thereto, which bolt extends over and secures the draft pipe to the body of the stove.

In converting this ordinary wood heater to a brooder. this cap is removed and a cap 23 is placed
