Figure 4 is a verticalfsectional View `on the line 1.---lof Figure 3. Y e F'gure is an end elevational vieWVof several'decks of. brooderswith the endwalls 75 v or grill'sbrolren a\vay,and Witlrlparts shown insection. i 4 i 1 Figure 6 is adetail perspectiveview of one'of 1. the chick trays or "removable ioors and certain ofits corelatedparts.` f i Figure 7 is affragmentary detail vertical `Figure 8 is a detail` perspective vievv of one of: the end Walls `or grill assemblies7 showing the parts inseparatedconditionl Referring to the drawings by reference y characters,the numeral `10` designates my improved compartment?\` broeder in its en- "tirety,` \vhicl`1 includes a plurality of broeder `sections ll arranged in deck or tierforlnation, that is, one upon. the other, and which broeder sections are supported upon an ele` vated base l2 from "which rise vertical posts 13 tculi'vhich the Walls of the broeder com partmentsware conne`cted-` In vievv offthek fact thateachone of thebrooderfcompart? ments is identical in constructiomI will only describe the construction `offene colnpalt` mentfwhich Will suffice for `the othe'rs.' y y V Each brood-er compartment l"llincludes grill side walls 14, each of which is provided with an upper feed grillrportion 15 constructed of a plurality of spaced ver- -tical bars and a lower babychick feed grill portion 1G which is in the form of spaced circular openings. The numeral 17 desi0'- nates end grill sections, each of which 1s provided with a central panel section 18 and an upper feed grill section 19 on opposite sides thereof beneath which are provided baby chick feed grill sections 20. The feed grill sections 19 are formed of a plurality of spaced vertical bars similar tothe portion 15 of the side walls, while the lower baby chick feed sections 20 constitute spaced eireular openings. The grill wall sections of one compartment are connected to the same walls of the next adjacent compartment by any suitable means but in the drawings I have illustrated dowell connections between these parts. By this construction, l produce a brooder of the knock-down or collapsible type to facilitate the compactvshipping of the structure and the erection of the same by any one unskilled in the art.
Associated with the side and end grill sections are visors 21, each of which coinprises a rectangular shaped frame 22 which supports a translucent panel 23. This panel 23 is provided with a screen 24 embedded in a glass body and which glass may be formed by spraying liquid glass upon the screen so that the same is received by the in terstices of the screen. Also, the translucent paneljmay be made of Cel-O-Glass, as set forth in U. S. Letters Patent No. 1,580,- 287. This glass from which the panel is formed may be of any desired color, such as blue, whichwill produce a subdued antiglare ultra-violet ray when light is passed therethrough for a purpose to be presently explained. Although,I have described the visor as being constructed of glass, the same may be made of other translucent material, and also,`the colors may be, red, amber, green, purple or the like if desired. Eyes 25 are carried by the top of the visor frame 22 adjacent the ends thereof and which engage hooks 26 mounted on the posts 13. By this hook and eye construction, the panels or visors'are removably supported in position, and have pivotal movement in order that the angularity of the visors may be varied or adjusted to regulate the ventilation within the brooder compartments. For adjustably supporting the Visors, I provide arms 27 which are pivoted to the post 13 by a thumb screw 28 and which screw when tightened is suiiicient to support the arm 27 inl an adjusted position. Extending inwardlyffrom the free end of each arm is a pin 29 disposed in the path of movement of the visor and on which the ends of the visor frame rest.
Extending inwardly from the end panels 18 are cleats 30 which support a pair of deflecting hovers 31, each hover constituting a semi-circular shaped member 32 and which pair are arranged centrally of the brooder compartment and extend lengthwise thereof. Housed within the hovers 31 are hot water heating pipes 33, which pipes are respectively connected to a hot water feed pipe 34 connected with a hot water furnace and with a return water pipe 35, which pipe is also connected with a hot water furnace to accommodate for the return iiow of the hot water after passage through the heating pipes 33. The 3ipes-34 and 35 rise vertically at one end of the brooder and the leadin branchesy are Arespectively connected tothe pipes Control valves 36 are provided with each branch pipe to regulate the heat of each compartment.Y It might be mentioned however that the hovers 31 are ele# {vated with respect to the bottom of each compartment to permit chicks to pass therebeneath, or to hover thereunder.
Supported by each of the end grill sections 17 are spaced horizontally disposed cleats 87 and 38, the said cleats extending inwardly from opposite ends of the end grill sections as best seen in Figure 8 of the drawings. The cleats 37 slidably support foraminated tray sections 39 which are constructed of a frame 40 in which a wire screen 41 is mounted. The outer end of each tray 39 is providedwith a feed pan seat 42 which extends beyond the side grill section when the tray section is in a fully inserted position for supporting feed trays 43, while the inner end of each tray frame is formed with a kerf 43 for receiving and supporting a vertical removablel partition 44. The height of the partition 44 is such as to permit the said partition to pass under the hovers or heat deflectors 31 so that when the tray sections are in fully inserted position as shown in Figure 5 of the drawings, the said partition serves to divide each brooder unit into two separate compartment-s, each compartment being provided with three substantially open sides. However, should it be desired tothrow the two separate compartments into a single compartment, the fioor trays 40 may be removed and reinserted with the partitions 44 separated therefrom.
It will therefore be seen that the chicks may be segregated in each brooder section, or if` desired, they may be given the free Arun of the entire section, merely by the use of the removable partition walls 44. By
reference to Figure 5 of the drawings, it will be noted that one of the slidable tray sections is in a partially pulled out position so that the partition 44 is disposed adjacent the outer edge of one of the heat deflectors 81 to shut off or regulate the heat` therefrom to the major portion of the compartment, or to prevent the chicks from hovering beneath the heat deflectors 31 when the temperature i zo " theirheads through the bars of the grill sections 19, or through the openings in the lower chick feed grills 20,`

of a room is suiiicient for the comfort of Slidably supported upon the" cleats 38l are dropping pans f `45 which are l insertible through opposite sides of the broeder com pertinent, and which pans are disposed directly beneath the foraminated floors or tray sections 39 for the purpose ofvcatching the droppings of thechiclrs `vv'hieh pass through the openings in the? screen ll. By this ar.-
i rangement, the droppings are notfcollec'ted upon the floor onjwhich the chicks aresup-v ported, but filth is collected uponthe drop-` ping pans which may be `removed when desired by `merely shdingthem from beneath the floor sectionsifor cleaning purposes.
Brackets le extend outward `from the end.
grill sections 17 and support Water' pans 47 which Water is accessible to `the chicks Within the compartments by the extending of From `the foregoing description, it Will be seenthat I have provided `a chick brooder which embodies la number of improvements i in broeder construction, chiefly among which v `4L() penses Withthe usual practice' of providing a` humidifier for the ventilating air.` Furisthe use of the ultra-violet ray producing -visors which permits `the ultra-violet rays of light topass into thechiclrcompartments With all their health giving properties, and which light rays produce a soft li which is inducive of the `health andy grovvthof the l baby chicks. Although blue or violet color raysliaveproven more beneficial than others,
` various other colored rays `may beproduced suchas red,`amber,`V green, purple and. the like. As stated, `the visors may be adjusted as their angularity to regulate the admission of natural air intothenbrooder Which disthermore, all the parts are removablefor permitting cleaning and disinfeeting `of the `same Which permits the maintenance ofthe broeder in a sanitary condition at all times.
The side` grill sectionsl 'are each provided With a door for facilitating access to `the interior of each compartment, but such door is only used for the purpose of insert-` ing and removing the chicks from theicompertinents, as the trays and drop pans are all slidable through the sidesof the broeder without reaching into the compartment.
