BROODER STOVE.

Application filed. August 29, 1925. Serial No. 53,310.

The present invention relates to improvement in broeder stoves and its particular object isto provide a stove ot simple construction in which a large heating surface is produced through direct contact with the products ot combustion and in which fresh air comes in contact with the other side of the heating surface and is discharged into the space provided for the growing chicks without coming in Contact with the products ot combustion. A further object ot the invention is to insure perfect circulation of air whereby fresh air is continually drawn into the heating chamber and discharged into the 7 space toward the burners to provide a charge that is preheated and insures rapid and smokeless combustion. i

It is further proposed in the present invention to provide a stove which may be readily taken apart and reassembled due to structural features of the same.

Further objects and advantages of my device will appear as the specification proceeds.

The preferred form ot my invention is illustrated in the accompanying drawing which shows a vertical central section throughmy stove.

While I have shown only the preferred form of my device, it should be understood that changes or modications may be made within the scope of the claims without departing from the spirit of the invention.

Referring to the drawing in detail it will be noted that a tube 1 is inserted in a hole 2 in the floor 3 and held in place by means of a flanged collar 4. A plate 6 is telescoped over the upper end of the tube which plate is supported by means of a. rusto-conical wall 7 in spaced relation to the floor 3 and so as to allow the tube 1 to project above the same. A tlange Son the plate leaves aspace between the flange and the upper end of the tube in which is accommodated a seoond tube 9 in axial alignment with the first tube while a fiange ll disposed near the rim of the plate 6 allows a cylindrical wall 12 to be centered relative to the plate and to be held in concentric relation relative to the tube 9.y The Jfrusto-conical wall 7 is perforated as shown at 13 so as to allow air to pass therethrough from the outside and the plate 6 is also perforated as shown at 14 to allow the said air to rise toward the burnrounds the spreader and is similar in form but somewhat larger in dimensions so as to be spaced from the spreader and to allow products of combustion to pass along the bottom of the spreader outwardly to turn around the edge and move centerwise along the wall toward the top and to be discharged into the stack 23. The bottom 24 ot the shell is formed with a central hole 26 somewhat smaller than the wall 12 so as to allow the bottom 24 to rest on the latter while a concentric ring 27 allows the shell to be centered relative to the cylinder 12. The spreader and the shell are held in properly spaced relation by means of spacing elements 31.

The whole device is surmounted by the conical root 13 supported in spaced relation relativeto the shell by means .of spacing elements 32 resting on smalllugs 33 projecting olutyardly from the bottom plate 24 of the sie Short pieces of pipe 34 connect the inside of the spreader with the outside ot the shell so as to allow heated air to escape trom the interior of the spreader' toward the root 18 without coming in contact with the products of combustion passing between the spreader and the shell.

The operation of my stove may be readily understood from the foregoing description.

-When the burners 15 are lit air is drawn through the perforations 413 oit the trustoconical wall 7 and the pertorations 1st of the. plate 6 to support combustion. The products of combustion rise between the tube 9 and the cylinder 12 until they strike the bottom of the spreader 16. They are then deflected to assume radial direction while in intimate contact with the spreader until they reach the edge of the bottom plate whereupon they again move centerwise in intimate Contact with the spreader and finally escape through the chimney 23.

The heating of the spreader causes air to rise therein and new air to be drawn in from below the lioor 3 through the tubes 1 and 9. This new air is heated while rising,` through the two tubes and absorbs additional units while within the spreader 16 whereupon it is discharged through the pipes 34: into the space below the roof 1S whence it is deflected downwardly and discharged into the space immediately surrounding the stove and occupied by the chicks. This heated air again is drawn upon by the burner in the manner previously described so that constant circulation is kept up and the chicks are provided with a. continuous supply o1c fresh and heated air.

Haring; described m3.' invention what I claim isz l. ln a broeder stove,` a vertical tube, a spreader having a tlal bottoni and a conical top communicating with the upper end ot the lube` a burner surrounding the latter, means surrounding the burner and the spreader allowing air to enter below the burner a nd guidingA the products ot combustion. around the spreader in intimate contact therewith tor discharge above lhc spreader and means allowing air entering through the tube into the spreader to escape through the top thereof without coming in contact with the products ol combustion.

2. In a brooder stove, a vertical tube, a spreader having a flat bottom and a conica top communicating with the upper end ot' the tube, a burner surrounding the latter, means surrounding the burner and the spreader allowing air to enter below the burner and guiding the products ot combus* tion around the spreader in intimate contact therewith for discharge above the spreader and means allowing air entering' through the tube into the spreader to escape through the lop thereof without coming in contact with the products oil? combustion, in combination with a root guiding the heated atmospheric air downwardly.

In a broeder stove, a vertical tube, a spreader having a tlat bottom and a conical lop communicatingrwilli the upper end ot' the tube, a burner surrounding the latter, a shell surrounding the burner and the spreader allowing air lo enter below the burner and guiding the products oli combustion around the spreader in intimate contact therewith for discharge above the spreader and pipes passing through the wall o'tl the spreader' and the shell allowing air entering through the tube into the .spreader to escape tlierc-llnougrh without coming:r in Contact with the products ot combustion.

il. lu a brooder stove, a vertical tube, a spreader having a llat bottoni and a conical lop communicating with the upper end of the tube, a burner surrounding the latter, a hell surrounding the burner and the V3prea-der allowing air to enter below the burner and `guidiirc`- the products ol combustion around the spreai er in intimate contact therewith 'tor discharging' above the spreader and pipes passing' through the wall ot the spreader and the shell allowing air enleriuggj through the tube inlo the spreader to ery-apc there-through without coming:Y in contact with the products olI combustion in coiniiination with a root guiding the heated air downwardly. i

ln a lwoo-ler Flore, a raised lloor, a vertical lulze extending` thereinto and fastened relative thereto, a perforated plate surrounding the tube, a lrusto-conical perforated wall supporting the plate in spaced relation to the tube, a second lube telescoped on thc hrst tube and resting on the plate, a cylinl ical element resting on the rini olf the te in spaced relation to the second tube a burner above the plate between the second tube and the cylindrical element.
