ESTA M. PIERCE, OF BOWLING GIR EEN, OHIO, ASSIGNOR TO THE BOWLING GREEN POUL TRY SUPPLY COMPANY, OF BOWLING GREEN, OHIO, A CORPORATION OF OHIO- cnrox BROODER.

Application filed June 27, 1927. Serial No 201,849.

This invention relates to chick brooders, and an object of this invention is to produce a new and improved brooder equipped with temperature controlled regulating means for maintaining the temperature at a predetermined degree within the brooder chamber,

and for providing adequate ventilation to eliminate the liability of foul and impure air within the chamber, thereby to enhance the healthy condition of the chicks. Other objects and advantages will hereinafter appear.

The invention is shown by way of illustration in the accompanying drawings, in which:

Fig. 1 is a diagrammatic view showing the brooder chamber and the means for maintaining the temperature within the chamber substantially constant Fig. 2 is a transverse section on the line-2-2 of Fig. 1 Fig. 3 is a front view in elevation of a portion of a chick receivin section and Fi 4 is aers ective view of one of the compartments or drawers for the chicks.

The illustrated embodiment of the invention comprises a brooder chamber 1 in which is positioned the chick-receiving section 2.

The sections are made up of tiers of trays or compartments 3 to recelve the chicks, each tray having wire mesh sides 4 and bottom 5.-

a0 Disposed beneath each tray 3 is a pan 6 to receive the droppings or refuse matter. As the detail construction of the sections forms no part of the present invention, further description is deemed unnecessary;

tions are electrically driven fans 7 supported by a suitable cage 8 suspended from the top wall of the compartment by supports 9. The motor for operating the fans 7 may be of the selective speed type and manually controlled by an operating lever 10. As shown in Fig. 2, any number of fans 7 may be employed to maintain adequate circulation and ventilation inside the chamber. The fans are preferably positioned intermediate the separate chick receiving sections so that an indirect draft is afiorded within the chamber and to prevent a direct draft on the chicks.

Extending transversely across the u per portion of the chamber 1 and disposed a ove the fans 7 is a series of heating coils 11 which may be supplied with steam vapor from a furnace 12, the inlet from the inlet duct 13 for the coils 11 leading from the upper. portion Disposed above and at one side of the sec- 7 11 areheated, the damper 16'may be opened so that warm pure air may be supplied to the. inside of the chamber.

Spaced from each inlet vent 15 is an air outlet vent 17 for foul or impure air, and, as shown, this vent is above. a chick-receiving section. It is to be understood that a set of air inlet and outlet vents may be provided for each chick-receiving section. Within the outlet pipe 17 is a damper 18 having an arm 19 for operating the same.

Mounted on the side wall of the chamber 1 is a thermostat 21 which operates at predetermined temperature limits to energize ,a motor 23 to which it is connected by wires 22. The motor 23 has arms 24 and 25 extending in opposite directions, and each time the motor is energized the arms 24 and 25'are moved through an arc of 180.

The arm 24 is connected by a cable 26 which is guided by suitable sheaves to a weighted arm 19 of the damper 18, the arm 19 extending in an opposite direction from the arm 24. The other arm 25 of the motor 23 is connected 4 by a cable 27 also guided by suitable sheaves to a Weighted arm. 20 of the damper 16, the arm 20 extending in a direction opposite from the arm 25. I

Also leading from the arm 25 is a cable 30 suitably guided by sheaves, and this cable is connected to the outer end of a weighted le- .ver arm 29. The arm 29 is connected to a valve 28 which controls the passage of steam through the inlet duct 13. Normally, the valve 28 is held open by the weighted lever 29.

When the thermostat 21 operates to energize the motor 23, it is apparent that the ampers 16 and 18 are concomitantly opened to allow the fan 7 to draw in fresh air through the vent 15 and expel foul air from the chamber through the vent 17. The arm 19 is lifts ed by the cable 26, but the cable 27 is slacked to permit the welghted arm 20 to turn the I damper 16 to open position.- At the same time that the dampers 16 and 18 are opened is controlled by a vaporstat 40 connected by a the cable 30 is released to permit the weighted arm 29 to close the valve 28, thereby shutting ofi the steam supply to the coils 11.

- After the chamber 1 has become sufliciently cool, the thermostat 21 again energizes the moton 23. The cable 26 is thereby slacked to allow the weighted arm 19 to turn the damper 18 to closed position, and the cable 27 is lifted to move the damper 16 to closed position.

It is manifest that the'temperature Within the chick chamber 1 is maintained substantially constant, and the foulgair is expelled constantly by permanent valves and that the interior of the chamber isfilled with pure warm air at all times. Because of the position of the fans 7 there is no liability of a direct draft on the chicks, and the inlet and outlet vents are so arranged that the most eflicient ventilation is maintained.

For automatically controlling the operation of the furnace 12, the usual check gate 31 is hingedly connected to the outlet pipe 32 of the furnace and the usual upwardly swinging ate 33 is mounted on the lower door 34 of the urnace. The gate 33 is connected by a cable 35 to an arm 36 of an electric motor 37, and the check 31 is connected by a cable 38 to an arm 39 of the motor 37, these cables being guided by suitable sheaves in the usual manner. The arms 36 and 39 extend in opposite directions and the motor 37 operates similar to motor 23 above described. The motor 37 tube 41 to the steam chamber of the furnace, and is also connected by leads 42 to the motor 37.

I The vaporstat 40 of well known construction, energizes the motor 37 at predetermined periods to provide uniform operation of the furnace. When there is suflicient vapor in the steam chamber, the gate 33 is ielosed and the gate 31 is opened, but should the steam fall below the requirements, the gate 33 is automatically opened and the gate 31 is closed to enable the furnace to operate more intensely.

While I have shown and described one embodiment of the invention, it is to be understood that numerous changes-in details of construction, arrangement and operation may be effected without departing from the spirit of the invention, especially as defined in the appended claims.

What I claim as new and desire to secure by LettersPatent is 1. A brooder having a closed chamber, air

inlet and outlet vents for said chamber, a fan in the region of said inlet vent for drawing air into said chamber and maintaining circalation therein, heating meansadjacent said inlet vent, means controlling the operation of said heating means, valves controlling said vents, and means common'to said valves and said cont-rolling means for automatically operating the same in accordance with the temperature conditions within the chamber.
