AUGUST R. LEWIS, OF KENT, WASHINGTON.

BROODER.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed September 4, 1907. Serial No. 391,310.

To all whom it may concern:

Be it known that I, AUGUST It. Lrzwis, a citizen of the United States, residing at Kent, in the county of King and State of Washington, have invented certain new and useful Improvements in Broeders, of which the following` is a specification, reference being had therein to the accompanying drawings.

This invention relates to broeders; and its object is the provision of a device Which will be of inexpensive and durable construction, which may be readily adjusted to accommodate young chickens of various sizes, and which will require but little attention on the part of the operator.

lith the foregoing ends in view the invention consists in the novel construction, adaptation and combination of parts as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a broeder embodying my invention; Fig. 2 is a longitudinal vertical section of the same, but with the hinged cover portion of the casing and the doors shown in an open condition; and Fig. 3 is a cross sectional view taken through 3 3 of Fig. 1.

The broeder proper is comprised of a casing, or box, having a bottom 5, sides 6, a front end 7, a back end 8 and a to 9. In the front end is an opening 7 provi ed with a hinged door 7". Said top is formed with an opening adjacent to each of its ends whereby access may be had to the interior of the casing and are provided With closures which are hinged to a transverse bar-.member 9 of the top. The closure for the opening 10, which is adjacent to the back end of the casing, is made of two parts 11 and 12, of which the rearmost one is the smaller and is provided with a pane of glass 12. The closure 13 for the other opening is also provided With a glass pane 13 Which is considerably larger than the pane of the closure 12 in order to admit the li ht to a greater degree toward the head en of the apparatus.

Within the casing is a Hoor 14 adapted to be adjustably sup orted at various heights and which may be conveniently done by props 15 which are hinged to the casing-bottom and have their free ends tiltably raised or lowered by lines 16 which are attached thereto and about a rotatable rod 17, as illustrated in Figs. 2 and 3. This rod is journaled in the side members of the casing and has an enlarged extremity 17 protruding outwardly from one of such sides and whereby the turning of the rod is effected. This extremity is provided with peripheral notches 17 for engagement with a pawlbolt 18 for securing the rod against rotation and thus maintain the floor, which is supported upon the props, at any adjusted height.

Just below the casing top are transverse poles 19 and 2() which are respectively disposed to be in proximity of the door 7 and below the top bar-member 9', and have ends, such as 20, extended outside of the casing for turning the same in order to raise or lower the curtains 19 and 20 which are rolled about the respective poles. Positioned within the casin and immediately below the closure part 11 1s a tank 21 formed with straight side Walls 22, a fiat cover-plate 23, desirably of metal, and a curved bottom 24, formed of a flexible sheet of rubber or equivalent material.

25 is a boiler of any appropriate size or shape, but preferably of the type illustrated and comprising an outer cylindrical shell 26 and an inner truncoidal shell 26 arran ed concentric with each other and affor ing therebetween a space 27 for the heating water which is supplied through an opening 26 having a cap 28.

A pipe 29 makes communication between the top of the boiler water-space and the top of the tank and similar connection is made between the bottoms of these elements by a pipe 30, and by such an arrangement a circulation of water is created in the heating system, as indicated by darts in Fig. 3, when heat is generated by the boiler. The pipes in passing through the casing are supported thereby and in turn sustain the boiler and, ordinarly, the tank by rigidly connecting the adjacent side wall of the latter with the pipes and extending one of the pipes, as 29, to be socketed within a recess 22 1n the remote wall. Pipe 29, adjacent its outer end is formed on its top with an opening 29', by means of which the Water passing through pipe 29, from the boiler escapes into the tank.

In broeders of uncommonly large size, resort may be had to suitable supports supplementary to the pipes, as above explained; however, it is advantageous to extend one of the pipes as shown in order that the intake and delivery of the water will occur at opposite sides of the tank and cause a cross current therein. The water is heated by a suitable heat generator, such as a lamp 3l having its chimney extended into the chamber 32 of the boiler and from this chamber the smoke or other con'ibustion gases are led away by a tubular conduit extending to within a short distance of the front end of the casing and thence through and terminating beyond the further side of the latter'.

There the conduit enters the casing an annular space is provided, indicated by 34 in Fig. 1, to furnish a delivery passage for a hot-air tube 35 which surrounds the conduit and reaching from within a short distance of the boiler to its entry to the casing provides thereby a duct for a supply of heated air to the brooder. The smoke conduit imparts heat to the current of air entering said duct and which is ample to maintain the compartment intermediate curtains 19' and 20 at a suitable temperature. Vent holes 36 are provided in the back end of the casing to allow of the escape of the foul gases emanating from the brooder-occupants.

37 represents an under cover of wool or leecy fabric for the tank bottom to protect the young poultry from coming in direct contact with the relatively hot tank and presenting a comfortable surface to nestle against.

In operation, the boiler is first filled, through the opening QG", with water at a boiling temperature, the lamp is then lighted and all of the casing closures shut. Then the brooder becomes heated to a suitable temperature, the chickens are introduced by raising the hinged part 12. Should the floor be found to be improperly adjusted to accommodate the chickens, it may be raised or lowered, as desired, by manipulating the rod 17.

It is found that extremely young broods will, as a rule, remain within the compartment to the rear of the curtain 20 and may be inspected through the glazed closure 12. As the chickens grow, they will pass into the cooler and better lighted compartment at the other side of this curtain and thence, when the external temperature permits, through the opening 7 to the outside. The temperature within the brooder is controlled throughV regulating the lamp and also the openin of the door 7 and the closures in the casing top.

The invention is well adapted for the pur poses for which designed, requiring but little attention, and its action is not subject to rapid changes in the surrounding temperature. The interior of the brooder is accessiv ble for cleaning and its occupants are at all times capable of being inspected.

What I claim is,-

1. In a broeder, the combination of a tank positioned interiorly of the brooder-casing, a boiler' positioned outside of the casing, pipe connections between the upper and lower' portions of the tank with corresjiionding parts of the boiler, a lamp for generating heat Within the boiler, a conduit leading from said lamp through the casing, and a tube surrounding said conduit and spaced therefrom having one end extending in the casing and the other end open to th 1 atmosphere.

2. In a brooder, a casing, a tank adjacent one end thereof, a central partition in said casing, means to heat water in said tank, a` conduit having connection with said heating means and extending across the opposite end of said casing, on the interior thereof to provide heat for the latter, and an air pipe surrounding1 said conduit and spaced therefrom, said air pipe having its outer end located on the exterior of the casing and being open and disposed adjacent said heating means and having its inner end leading into said casing, said conduit heating the air during the passage of the same through said air pipe into said casing.
