To all whom it lmay concern:

Be it known that l, FRANCIS S. BARZEE, a citizen of the United States, residing at Everethin the county of Snohomish, State of 1Washington, have invented certain new and useful Improvements in Incubators; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rl"'his invention relates to new and useful improvements in incubators and in its broad conception7 comprises a tank for circulating hot water and disposed in proximity to the egg tray and an air chamber surrounding the tank and opening into the interior of the brooder.

ln connection with a brooder of the above general type the invention aims as a primary object to provide a novel Ventilating system, automatic in its action whereby an adequate supply of warm fresh air and evenness of temperature is assured.

The invention aims as a further object to provide a novel construction, combination and arrangement of parts the details of which will appear in the course of the following description, in which reference is had to the accompanying` drawings forming a part of this specification, like characters of reference designating similar parts throughout the several views wherein- Figure 1 is a front elevation of an incubator constructed in accordance with the present invention. Fig. 2 is a central longitudinal vert'cal section thereof. Fig. 3 is a horizontal section thereof illustrating the construction of the water tank and the relation of the supply and drainage pipe. Fig. eL. is a vertical section taken centrally at right angles to Fig. 2.

In the accompanying drawings the numeral 5 designates the supporting legs and the numeral 6 designates generally the broeder supported thereon. The latter comprises a box formed with a bottom 7 and vertical outer wall sections 8, uponwhich is supported the top wall or lid 9. Imposed upon the bottom 7 are central wall sections 10 of less depth than the outer sections and disposed in similar arrangement but in spaced parallel relation. The sections 10 support at their upper ends a metallic top plate 11 and a dead air chamber 12, packed with heat insulating material 13 occurs con- Ijointly between the several wall sections 8 and 10 and the top plate 11 and the top or lid 9. A third inner series of wall sections 14 are supported upon the bottom 7 within the contines of the sections 10. The sections 14- are of less depth than the sections 10 and are arranged similarly thereto in spaced parallel relation. The spaced relation between the various sections 8, 10 and 14 is maintained by cleats 15 imposed upon the bottom 7 and arranged between the several series of wall sections. Hthin the confines of the sections lit are parallel cleats 16 which support a floor 17 spaced away from the bottom 10, heat insulating packing 18 being interposed between the bottom 17 and the floor 7.

The front wall sections of the various series above described are suitably constructed with registering op-enings to permit of the insertion and replacement of an upper egg tray 19 and a lower nursery drawer 20 having front panels 21 and 22 of glass. The side sections 14%. are of course constructed to support the tray 19 and drawer 20. lThe tray 19 is formed in its bottom with openings 19a through which air circulates to the nursery drawer 20. Said tray 19 is arranged below the upper edges of the sections 14e, in order that the latter may support in spaced relation to said tray, a water tank 23, the vertical walls of which form substantial continuations of the sections 14 and in such relation, together with said sections, coact with the sections 10 and the top plate 11 to afford a continuous warm air circulating chamber 24. provided with draft openings 25, equipped with suitable ventilating closures 26, the openings being formed in the rear wall sections 8 and 10. The sections 14e likewise support slightly below the tank 23 and spaced therefrom, a distributing plate 23a having a central draft opening 23h. The chamber 24 coniniunicates with the space 27 occurring between the tray 19 and the tank 23 by means of openings 28 formed in the sections 14.-. An open ended ventilator pipe 29 passes centrally through the tank 23, the top plate 11 and the top or lid 9, the pipe 29 registering with the opening 23b and communicating by means of said opening with the chamber 27. The projecting upper of the pipe 29 is closed by a damper plate 30 carried by the thermostatic arm 31, the latter being mounted upon a bracket 32, supported on the top or lid 9.

end

Water is fed into the tanli 23 from LPlmP or elevated source of supply by means of a ne'ction by niea'i'is of a Ty union 37 with lati erally extending* pipes 358 similarin arrangement to the pipes A moisture pan 39, surrounding the pipe 29 is imposed upon the top' of the tank'28 and' a feed tube or pipe L10 leads into thel said pan. The latter is designed to' contain Water for" thefpurp'ose' of st i'ppl'yii'ig moisture to the heated circulating air.

In use, when the temperature rises above a predetermined limit the plate 30 rises and air entering through the openings Q5, circu' lates through the chamber 9A, passing through thek openings 2S and chamber 27, ont, together with' poisonous gases', through the pipe 29. The ventilation lis thus automatic and the hot Water, continuously circulating' through the' tank assures of the evenness of the tem'peraturei AInasmuch as the Water@enters'adj'acen't,the bottom at one side o'f the tank and discharges from points adjacent the bottoni at the opposite side of said tank', the discharging Water be! 'lng cooler than the entering Water-,the heat will rise and hence the air 1n the upper" part of the chamber' 24' is Warmer than the air inthe chamber 27, the air descending v and passing into saidA chamber being moditied by the cool air entering through the openings 25.

The invention is simple "in its structure v and details, inexpensive to manufacture andv practical and elicient in use.

From the foregoing" description it Will be seen that simple and etlicient means are provided vfor accomplishing the advantages of the' invention but,l While the achievements l1`erei`n`- shown and described are Well adapted to serve the functions set forth it is obvious that any minor cl'i'anges may be' made in the proportion, shape and' arrangement of the several parts Without departing` from the scope' of the i1'rvention as designated in the appended claim;

W'hat is claimed is In an incubator, a casing, vertical wallsrising from bottom of said casing' and removed distance from thesidesof thelatter, andj containing opposed openings, a Water tank mounted upon said vert-ical Walls, andr
