lwwmw Earrg 527M132 PERRY S. MARTIN.'OF BROADWAY, VIRGINIA.

BROODER.

Application filed August 30, 1913.

T all whom it may concern Be it known that I, PERRY S. MARTIN, of Broadway, in the county of Rockingham and State of Virginia, have invented certain new and useful Improvements in Brooders,

whereof the following is a specification, reference being had to the accompanying drawin s.

lhe invention relates more particularly to that type'of brooders wherein the heat is deflected downwardly onto the floor or surface where the chicks are hovered. To this end the heater is provided with a cylindrical magazine'which forms an upward extension thereof of appropriate height and to the top of this upward extension an annular deflector is attached surroundingthe feed opening at the top of the magazine. A further object of the invention is to provide a brooder of the above type wherein the heated combustion gases may be passed in and about the radiator and the heat therefrom deflected downwardly onto 'the hover A further object of the invention is to provide a device of the above character with a thermostatically controlled device for regulating the draft of the heater.

These and other objects will in part be obvious, and will in part be hereinafter more fully described.

In the drawings which show by way of illustration, one embodiment of the invention, Figure I, is a plan View of a brooder embodying my improvements. Fig. II, is a vertical sectional view on the line II, II, of Fig. I. Fig. III, is a horizontal sectional view through the radiator, also showing the thermostat for controlling the draft. Fig. IV, is a detail on the section line IV, IV, of Fig. III.

The invention consists broadly in providing a heater which is preferably of the coal burning type, which is so constructed that the combustion gases may be caused to pass in and about a radiating chamber before be ing passed'to the chimneyflue; A damper is located so as to control the'd raft of said flue and this damper is connected to a thermostat so that it may be automatically positioned to maintain a.uniforn1 temperature underneath-the brooder. In order to the better maintain circulation of air be neath the deflector, the chamber is so l o Specification of Letters Patent.

catedthat the draft for the flue is derived altogether from within the deflector. This deflector is a conical annulus. The heater is provided with a magazine which forms a cylindrical upward extension to or near the top of which the deflector is attached. It is preferably formed of galvanized iron so as to more efficiently deflect the heat from the radiator downwardly upon the hover floor.

Referring more in detail to the drawings, I have shown a heater which is provided with a fuel chamber 1, having a grate 2, of the usual character. Coal or other fuel is supplied to this chamber 1, by a magazine 3, which is closed at the top by a detachable cover at. This magazine is cylindrical in shape with feed opening at the top, and in addition to extending downwardly within the combustion chamber 5, to proper proximity to the fuel chamber, extends upwardly above the combustion chamber a considerable distance. -The combustion chamber 5, above the fuel chamber, is connected by an opening 6, to a radiating chamber 7. The radiating chamber 7 is formed with a cross partition8, so that the fuel gases leading througl i the opening 6, into the radiating chamber are caused to pass about said chamber in the direction of the arrows in through an opening 9. Thisopening 9, leads to a fine 10, which is connected to the main chimney flue 11. The magazine 3 also supports a cone-shaped deflector 12, which finds attachment at or near the'top of the magazine, which maybe provided with an annular corrugation near its upper end, as shown in Fig. II, for the purpose of the better supporting the deflector. This deflector 12, is larger than the radiator so as to form a passage 13, between the deflector and the radiator. The lower end of the deflector is provided with a strengthening rib 14. The flue 11, passes up through the deflector, as is clearly shown-in Fig. II.

The opening 9, leading from the radiator chamber to'the flue 10,'is controlled by a. damper 15. This damper 15, is'adjustably attached to a lever 16, fulcrumed at17, to a supporting frame'18. The lever 16, is conneeted at 19, to a'diaphragm thermostat. The frame 18, is supported by the radiator, which, in turn, is attached to the heater. The lower wallofigthefiue 10,-is provided From the above construction it will be apparent that the heated. combustion from the fuel chamber will pass through the opening (3, entirely around the radiator and out through the opening J. From thence the fuel gasses pass through the flue l0, to the chimney line 11. The damper 15, therefore, directly controls the draft of the heater, as it controls the passage J. This damper is controlled by the thermostat, which is positioned well down toward the fioor of the hover, and, therefore, said thermostat will automatically shift the dainper so as to control the draft and keep the temperature of the air underneath the deflector substantially uniform. By adjusting the collar 21, the temperature maintained underneath the dcllector may be varicd.

By my improved construction, wherein a coal burning heater is used, very little care is necessary, as the supply of fuel located in the magazine will gradually feed the fire, thus producing for a long period an even heat.- The deflector is provided with a door 23, which may be raised to facilitate access to the heater for operating the grate-when desired. The deflector 12, is preferably formed of galvanized iron, or some other suitable metal wherein 'the inner surface thereof may be of light color so as to more efiiciently deflect the heat downwardly onto the hover floor.

It is customary to attach a curtain to the periphery of a deflector or hood such as is employedwith my heater, but in my construction this may lie to a considerable extent, if not entirely, done away with mving to the downward radiation of heat from the radiating chamber 7, which renders the space beneath the deflector sulliciently warm. At the same time, the position of the opening 20, through which air is drawn into the flue 11, is such as to insure the proper amount of fresh air beneath the deflector.

It is obvious that minor changes in the details of construction and the arrangen'ient of parts may be made without departing from the spirit of the invention, as set forth in the appended claims.

Having thus described my invention, I claim:
