BROODER.

SPECIFICATION forming part of Letters Patent No. 442,007, dated December 2, 1890.

Original application filed July 13, 1889, Serial No. 317,481. Divided `and this application filed June 30, 1890, Serial No. 357,301. (No model.)

To @ZZ whom t may concern:

Be it known that I, GEORGE Il. BISHOP, a citizen of the United States, residing at Northport, in the county of Suffolk and State of New York, have invented certain new and useful Improvements in Broeders, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specilication.

This application is a division of my original application, Serial No. 317,481, filed July 13, 1339, for improvements in incubators.

My invention relates to improvements in brooders, or socalled artificial mothers, for rearing young fowls or chicks; and the objects of the invention are to provide a brooder of a simple construction, wherein the air may be continually circulated and maintained at or about a uniform temperature.

In the accompanying drawings, illustrating an embodiment of my invention, Figure 1 is a sectional View of my improved broeder, taken on a vertical plane through the center of the apparatus; and Fig. 2 is a horizontal sectional view of the same.

Referring to the drawings, in which like numbers of reference designate like parts, S designates the brooding-chamber, the walls of which are double, with a considerable space 9 between them. y This space 9 may be packed with a suitable non-conductor of heat, or may be left as an airspace to act as a heat-retaining jacket for the chamber to prevent the rapid radiation of heat therefrom. One side of the chamber is provided with a door 10, through which access may be gained to any part of the interior of the chamber.

The air is introduced iut-o the upper part ot' the chamber 8 through means ot' pipes 11 11, shown, preferably, as four in number, and located one near each corner and running from the outside of the bottom of the chamber vertically through space 9 to nearthe top, thence extending horizontally into the center ofthe chamber, where they open into a common dischargepipc 12. The induction-pipe 12 is arranged vertically, and has a closed bottom and an open top or mouth, which empties almost directly against the upper side of the chamber. The air is led from the chamber S by means of a set of outflow-pipes 13 13, that run radially from the centrallydisposed eduction-pipe 14, provided with deflector 15, and set down through the inner wall of the chamber. The outflow-pipes 13 13 are arranged within the space 9 and extend horizontally from the eduction-pipe 11- one to each corn er of the chamberthence u pwardly to the top of the chamber and hori` zontally inwardly to the center of the top side thereof, where they open into a tlue 1G, that is set down through the outer wall of the chamber, and is provided with a defiector 17 for checking the outflow of the air, in order t0 produce a sluggish movement thereof through the chamber and avoid strong drafts. The air is heated to the desired degree as it is introduced into the chamber by means of a hotwater tank 18, which is disposed horizontally in the upper part of the chamber, so that the air, almost immediately upon entering the chamber, may be passed over the radiating-surface of the tank, and thus warmed before passing down to the lower part of the chamber to the broeder-cage.

The tank 18 is made of a suitable metal, and is connected by the circulating-pipes 33 3a 35 with the water-heater 19, which supplies the Water thereto, and is heated by a lamp 36, set on a bracket Li1.

No claim is here made to the hot-water tank 1S, the heater 19, and the lamp 36, though the same are my inventions.

Near the bottom of the chamber S is located the brooder-cage 52, having the sides and top thereof formed of suitable open-work.

'In the construction shown the cage consists in a door 49,suitablyclevated and supported above the bottom of the chamber with side walls 53, made, for instance, of gauze-work. The top of this cage is covered by an openwork screen, comprising the gauze 47 set in a frame 50, which is supported loosely on blocks 51. From the gauze 17 are hung the broeder-strips 4S, which may be placed as close together as desirable, so as to present a suitably dense mass. These strips are pref- IOO erably made of flannel, though any suitable materia-.l may be used, and are designed to `take the place of the feathers of the natural mother hen. The broeder is so situated that the Warm air in passing from the heater 18 to the dischargeflue 14 will circulate freely through and about the broeder-cage, so as to supply in a uniform manner the heated fresh air to the chicks. If desired, evaporationpans may be used With the brooder vfor the purpose of moistening the air.

The discharge-pipe 12 and the inner ends of the air-pipes 11, being located near the top of the chamber immediately above the heating device 18, these parts will be heated to such a degree as to cause the lower ends of the pipe 11 to suck in the fresh air and empty it in the upper part of the chamber, thereby insuring a good circulation of the air.

Havingthus described my improvements in brooders, what I claim as my invention, and desire to secure by Letters Patent, is-.-

1. A broeder-cage consisting in the combination, with the floor 49 and the side Walls of the cage, of a gauze top 47, the strips 48, made of fabric or like material doubled upon itself and hung over the strands of the gauze 47, with the free ends thereof depending into the cage, substantially as and for the purpose set forth.

2. In a broeder, the combination, with a chanrberS, provided witha heating device for warming the air therein,of abrooder-cage 52, locatedtnear the bottom of the chamber and having its floor 49 elevated above the floor thereof, and a space between the sides of the cage and the sides of the chamber, the said cage being provided With aperforated or openwork top 47, having strips of fabric 4S orlike material hun gtherefroimasystem of in flowai rpipes 1 l,extending from theeXterior of the bottom of the said chamber and vertically to near the top thereof, then horizontally inwardly to near the center of the top of the chamber, where they empty, a set of outflow-pipes 13, extending from about the cent-er of the bottom of said chamber at a point between the floor of the same and'the broeder-cage to the exterior' of said chamber at the top thereof, substantially as and for the purpose set forth.

In a brooder, the combination, with a chamber S, having a heating device for Warnr ing the air therein, of a broeder-cage 52, located near the `bottom of the said chamber, with its door 49 elevated above the bottom thereof, and-having a space between its sides empty, the eduction- pipes 14 and 16, located,`

respectively, at the bottom and top of said chamber, the one opening into the chamber and the other opening to the exterior thereof,

a set of imiow air-pipes 13, extending around the sides of the chamber and connecting the said pipes 14 and 16, for discharging the air from the chamber, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand, this 19th day of June, 1890, in the presence of the two subscribing witnesses.

G. I1. BISHOP. Witnesses:
