PATENT OFFICE .mm E. carbon, Farmville, conn., animar a YThe Trumbull Electric Manufacturing Cornpany, Plainville, Conn., a corporation of Con-v necticut Application November 15, 1934. Serial No. 753,093
SCIaiml.
My invention relates particularly to devices and apparatus for the care of chickens.
The main object is to provide a brooder which is safe and healthy for the chicks. I have especially sought to provide a construction in which there will be a warm air circulation automatically controlled as to temperature, free from drafts and entirely iree from any danger of suilocation due to open llame heating.
vOne object is to provide va construction which is simple and inexpensive and yet eifective.
' A special object is to provide a construction the parts of which can be made up and sold in compact units to be erected by the purchaser.
l5 Another object is to provide a heater unit adapted for use as a part of a brooder, the remaining parts to be erectedlby the purchaser with ordinary boards.
The preferred brooder construction includes a heater unit which forms the back of the housing for the chickens. The sides of the housing and the roof may be formed of ordinary boards. The heater unit includes a resistance heater wire and lamps together with athermostatic control for the resistance heater and is so constructed as to ensure proper circulation of the warm air.
The root of the brooder is hinged to the heater unit and adjustable so that it can be raised at its outer end as the chickens grow. Fig. lis a perspective view of a brooder construction embodying my invention. V
Figs. 2 and 3 are perspective views of a heater unit viewed from the inner side and the outer side respectively.
Fig. 4 is a view of the inside of the heater unit, parts being shown in section.
Fig. 5 is a cross section of the heater unit on the plane of the line 5-5 of Fig. 4.
Fi'g. 6 is a horizontal section on the plane of the line 6-8 of Fig. 4.
Fig. 7 is a side and sectional view oi the brooder showing the hinged roof or top and its support.
In the preferred form of apparatus the heater unit has a box or casing formed of sheet metal with a back plate I0, a front plate II, a bottom plate I2, a top plate I3 and end plates Il all united in any suitable manner. This box is provided with upright partitions I5, I5 secured to the front of the back plate Il and which reinforce the front and back plates and divide the box into a central main chamber or compartment It and end chambers I1.
The front plate and back plate are preferably u separable so as to permit access to the interior and the end plates are formed as flanges o! the iront plate.
The back plate has a number of inlet open# ings Il for letting cold air into the central chamber near the bottom and the front plate has 5 outlet passages Il for warm air near the top.
The end chambers have air inlet passages 2l in the front plate near the bottom and outlet air passages 2I near the top of the back plate.
The heating is effected partly by a resistance l0 element 22 located in the center chamberbetween the level of the air inlets il and the outlets Il and partly by one or more electric lamps 23 and 2l located in the upper part of the box. These heater elements are suitably supported prefer- 1l ably by an insulating plate Ill on the back plate oi the box and the lamp sockets are arranged in line with openings 23 so that the lamp bulbs may be inserted through the front plate and so that the lights will shine into the brooder and m thus attract the chicks. The sockets for the lamps 23 and 23' are so connected or wired into the circuit that lamp 23 will burn continuously Vto attract the birds while lamp 23' is in circuit with the heater so as to indicate when the heater 25 circuit is on and to go out when the heater circuit is automatically interrupted and thus indicate the condition of the circuit.
'Ihe temperature is regulated by the action of a thermostaticdisc 24' and a connected switch 25 30 in circuit with the resistance element 22, the parts being designed and adjusted to maintain the desired temperature;
The housing for thebirds is formed by the heater unit just described together with the side boards 26, 26, the top or roof 21 and the curtain 2l. The side boards may be secured to the end flanges Il of the heater unit by screws 32 and the roof may be hinged at 28 to the upper edge of the heater unit or may be pivoted to the sides 40 2l of the housing.
The side boards are provided with a number of openings 3|! for receiving a cross bar 3| upon which rests the outer edge of the rooi 21. The .roof can be readily raised for inspection and cleaning. By adjusting the height of the supporting bar 3i the opening for the birds to enter and leave can be varied and the outer end of the cover may be adjusted to suit the size or height of the growing chicks.
The heater unit may be-provided with a suitable attachment plug 32 and cord for convenience in installing the device whenever desired.
When the brooder is in use the outside or cold air enters the heater chamber through the u '2l to the outlets 2i.
2 openings Il and rises past the heater wire 22 and through the outlets I into the housing. 'Ihe warm air striking against the inclined roof 21 is deilected downward away from the heater unit and. of course, some oi it escapes from beneath the curtain 29. The warm air circulatesA in the housing and some oi' it escapes from the openings 2l into the end chambers i'l of the heater unit and thence out through the openings 2i. 'Ihe heatfrom the central chamber tends to expand the air in the end chambers, and thus creates a flow of air from the inlets The air in the brooder is thus kept circulating slowly and kept at the desired temperature suitable for the protection of the chicks. Y
- It will be seen that this construction provides a very cheap heater unit which is portable andv may be set up or moved anywhere, or when not in use may be taken apart and stored away in a very small space. The unit is complete in itself in that it carries all of the electrical fittings' and 4means for directing the flow of the heated air and for properly Ventilating the interior of the brooder section without cold drafts.
Obviously this construction lends itself to a wide range of dimensions as the thermostatic switch is adjustable thus permitting the brooder proper .to be comparatively Wide or it may be of narrower dimensions where space will not permit the larger dimensions. This feature also allows for adjustment of the'brooder proper to the number of chicks which it is desired to brood. A
' commercial size of brooder may be adjusted and a arranged to brood from 50 to 150 chicks. Again 'inlet openings near the bottom, the wall of the unit between the inside of the brooder and the heater having outlet openings near the top where- "by` outside air is caused to rise, pass oven-the "hater, and lberlischarged into the brooder" adjacent the top, and a temperature responsive control mechanism for the heater located in' the brooder but carried by the unit, the rof' of said brooder being pivotally secured to the tgp of sai'd unit, and the walls of said brooder being provided with means for adjusting the height of the portion of the roof remote from saidfpivotal mounting.
2. A portable heating and Ventilating unit adapted to be detachably secured to the top and side walls for a brooder and including spaced top, bottom. side and end walls, an electrical heater mounted between the walls of said unit, the front and back walls of the unit being provided with Ventilating openings arranged to cause outside air to enter between the walls, rise and pass over the electric heater and be discharged into the brooderadjacent the top, at least a portion of said electric heater including a socket secured in the space between the front and back walls and an electric lamp bulb mounted in said socket and located at least partially within said unit to assist in heating the air within the unit, said lamp bulb being readily visible and accessible through a wall of the unit, and 4a thermostat mounted on the outside of 'the front of the unit, said thermostat being connected with at least a portion of said electric heater for controlling the same in response to the temperature of the air within the brooder.
