BBOODER.

To al? whom it may concern.'

Be it known that I, JOHN FrMAcKAY, a

'citizen of the United States, residing at Bordentown, in the county of Burlington and State of New Jersey, have invented certain -new and useful Improvements in Broeders, of which the following is a specication, reference being had therein to the accompanying drawing.

This invention relates to broeders for raising incubator hatched chicksyand the principal'object of the invention is to1 produce a simple and efficient colony broeder suitable for use either indoors or in the open `and which will accommodate and safely care for a large number of chicks.

One-object of the invention is to simplify Vand improve thehea'ting apparatus, a coal stove or heater rbeing employed.`

A further objectof the invention is to simplify and improve the means whereby the heat is regulated.

A further object of the invention is to produce a coalvburning brooderheating apparatus to which fuel may be fed from the top without disturbing the broeder.

With these and other ends in view which will readily appear as the nature of the invention is better understood', the same consists in the improved construction and novel arrangement and combination of -parts which will be hereinafter fully described and particularly pointed out. in the claims.

- Iuthe accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood 'that nio limitation is necessarily made to the recise structural details therein exhibited, lint that changes, alterations and modifications ivithin the scope of the claims may be resorted to when desired.-

-In the drawingY Figure 1 is. a side elevation, partly in section, of a device constructedl in accordance with the invention'.

Fig. 2 is a top plan view of the same.

Corresponding parts in the several iigures are denoted =by like characters of reference.

'i The heater of the` improved brooder consists ofv a stove or furnace A of which 5 denotes thefire box 6 the grate, and 7 the ash pit for which a draft door 8 in provided, said door being hinged at its upper edge, as shown, so that it will naturally gravitate Application for reissue I Speclcation of Beissued Letters Patent.

to a closed position. The stove body, which has been 'shown as tapering upwardly, is provided at its upper end with a hopper B, the discharge opening of which, 9, is -adapted to constitute a seat for a valve or damper 10. II he hopper B, the upper portion of which flares beyond the stove body, is provided with a top plate 11 having an opening coveredby a lid 12 which is located directly above the discharge openinnr 9 of the hopper. The lid 12 is apertured for the passage of the stem 13 that extends upwardly from the valve or damper 10. `The Y top plate has an opening 14 which is located at one side thereof substantially in vertical alinement with the draft door 8; a valve orv damper 15 whereby said opening may be obstructed is hinged adjacent to the outer edge of the opening, said damper being provided with an outwardly extending arm 16. A fiue 17 for carrying olf the products of combustion is mounted ori the top plate 11.

Fulcrur'ned on a support 18 which rises from the top plate 11 is a lever 19, onev arm of which is connected with the4 valve stem 13 and with one end of a flexible element 20,

which latter is connected at its lower end i 19 carries a counterweight 21 for approxi-.

mately-balancing the valves.10, 15 and 8. The'parts are so arranged that'when the door or `valve 8 is wide open, the valve 15 will be seated, and the valve 1() will, likewise be wide openl to permit products of combustion to pass from the fire box to the exit due 17. As the valves Sand 10 move in the direction of their respective seats the check valve or damper 15 will gradually be unseated.

A thermostat 21 is supported on abracket 22 extending from the stove body, said thermostat including a rod 23 which is guided through an aperture 24 in a portion of the top plate 11 which overhangs the stove body. The rod Qis connected with the arm of the lever' 19 that carries the counter-weight 21 by means of an intermediatelever 26 fulcrumed on the upright 18 and a connecting member 28, said lever and connectingm'ember being introduced for the purpose of increasing the movementl of the lever. 19 relatively to that of the rod Q3, thereby rendering the operation of the device more efective.

The top plate 11 supports a downwardly flaring hood D which'for convenience may be composed of hingedly connected members 29, 30, one of which may, furthermore, be provided with a door 31 through which access may be conveniently had to the interior for the purpose of removing ashes 'from the ash pit 7 andthe like. A curtain 32 of flexible "material depends from the lower edge ofthe hood D and terminates a short distance above the ground so as to afford ample protection while not hinderingthe ingress and egressiof the chicks.

The operationand advantages of this invention will be readilyunderstood from the description taken in connection i foregoing with the drawings. Coal may be conveniently` fed to the stove by manipulating the lever 19 so as to raise the valve 10 to a nonobstructing position. 'and then sliding the `lid 12 upwardly upon the valve stem; the

fuel may then be introduced and will be guided over the downwardly inclined walls of the hofpper throulgh the aperture 9 and into the re box. he valves or dampers will be automatically operated to regulate thevdraft so as to maintain 'the temperature evenlyat a predetermined degree. The general construction is simple, inexpensive and thoroughly efficient for the purposey for which it is provided.

A thermometer 35 lis provided to enable the temperature within the hood to be ascertained, 4and in the hood is formedy a hole f 30 through which the thermometer may be viewed. l y y It will be seen that the htop plate covering the hopper extends laterally beyond the perimeter thereof all around the heater. This is a decidedly advantageous arrangement in a heater for abrooder, as it perf.`

mits a hoodiof simple truncated cone form like `that illustrated to be easily applied toand supported by the said plate, no particular fitting and shaping of the parts with reference to each other being necessary ,to secure practically air-tight joints when they areunited.` It will also `be observed that the rheans by which the draft controlling dampcrs 8 and 15, and trolled-the levers 19, 26, ete-fare supported by the said top plate, thusumaking a se `fcontained apparatus, or one supported by a single, base. The check draft opening 14 is' in thetop plate and hence exposed, so that when the damper ,15 is open the air taken in to cheek the draft" isdrawn lfrom the open,

temperature within the latter is notlowered I outside ainwhen the check dnmpenislopencd. Furthermore by making tlgie'hcater with anfopening in its top through i which fiielfmay bemfefl to the fire chamber, and applyingthe hood so that ii? surrounds the heater butfdoes not cover thetop, I am ducing the closure 10', are con` enabled to practically use a coal or other solid fuel burner as the heater for a brooder and to replenish the fire with fuel from time to time as occasion requires, without having to open the broeder chamber, with the incident disadvantage of the loss of heat and danger from the confined air being contaniinated by v It will be seen that the hood which surrounds the coal-burning stove or heater A, considering thcl plate 11 as the top of the hood, is closed in its upper portions, and thereby traps a body of air that becomes highly heated from contact with the walls of the fire chamber of the stove. The flaring, depending, walls of the hood operate to deflect the hot air from the upper portion of the chamber toward the floor, thereby causing a circulation within tlie'hood chamber and insuriii r that there shall be a mild the escaping gases of combustion.

heat maintaine just above lthe floor space and within `the contines of the broeder, where the chicks congregate. The dierences in temperature between the upper cont-ractcd portion of the chamber inclosedvby the hood, and -the `lower `expanded partsy thereof occupied by the chicks, are very great, the temperature of-the upper part being very high and subject to considerable fluctuations, according to the condition of the fire within the heater A and ofthe outsidey temperature, while that in the lower parts ofthe ybrooder chamber is much lower and is' morefuniform; and in this respecta broedeiheated by aistove burning solid fuel and arranged as shown in the drawwhere the more uniform temperature conditions are sought to be maintained by introiiito the brooder" chamber a con-v stantly renewed supply of heated air and products of combustion directly from the y lamp. It therefore becomes desirable in :in apparatus such as mine, to locate the ther"i mostat in the lower part of the brooder chamber Where the conditions approximatey those of the portion occupied by the Vchicks themselves. v.
