INCUBATOR AND BROODING HOUSES 



MODERN INCUBATOR HOUSES 



DETAILS AND PLANS OF INCUBATOR HOUSE THAT IS MODEL OF CONVENIENCE- 

 SAVING TIME OF OPERATOR— MATERIALS REQUIRED FOR INCUBATOR HOUSE— THE 

 INCUBATOR CELLAR — SMALL INCUBATOR HOUSE — HOW CONSTRUCTED, ETC. 



While any piece oj machinery nuill perform its destined mjork for 

 a time under sudden senjere changes of temperature, exposed to damp- 

 ness and inclement iveather, still anything made of nvood and metal 

 is necessarily perishable and it sho'ws good sense for us to operate any 

 machine under the most Ja'vorable conditions possible. To obtain the 

 best results 'with an incubator, 'we should place it in the best location 

 possible. 



E'veryone cannot build an incubator cellar for one or tnvo machines, 

 but each can use common sense in locating the machines in a 'well 'ven- 

 tilated cellar room, and 'with the aid of a thermometer keep the sur- 

 rounding temperature from 'varying many degrees. Do not put the 

 machines in the attic in the summer nor in an unheated out-house in 

 the dead of 'winter. 



You may get an excellent hatch under the most ad'verse condition, 

 but you are unfair to the machine and its manufacturer. — Editor. 



HILE many illustrations of incubator cellars or 

 houses have been published from time to time, 

 we do not recall that any plans have ever been 

 offered which showed a dark room for testing 



The incubator house shown in accompanying 

 plans, was designed by Dr. P. T, Woods, and a 

 house of this pattern is now in successful 

 operation at the Millville Poultry Farm. 



On aU plants where a considerable number of machines 

 are run, the testing of eggs becomes an item of considerable 

 labor and consumes a large amount of time. If this testing has 

 to be done at night, it lengthens the hours for the poultryman 

 so much that during the hatching season he loses a great deal 

 of much needed rest, whereas if some means are provided for 

 testing the eggs during the day, there are usually odd moments 



when the work can be done without interference with the reg- 

 ular routine of the plant. It was for this purpose of saving night 

 work on the poultry farm that the incubator house with dark 

 room was devised. This house, or more properly, half-cellar, 

 is a frame building built above a brick foundation, a slight ex- 

 cavation being made and a 2 feet 6 inch or 3 feet brick wall 

 built, against which the earth is banked up on the outside and 

 on which the sills of the frame building are laid. 



The sills are laid in cement to make a tight joint. The sides of 

 the building are sheathed with rabbeted pine boards laid length- 

 wise on both sides of the studs. The lower board reaches be- 

 low the sill and laps over brick work to avoid draughts. 



The roof is of rough boards laid on rafters which are placed 

 2 feet apart and is covered with a good quality of shingles. 



These rafters and frame are afforded additional support 

 by tie beams, as indicated in plan. (lU. 18.) 



The nine windows of the building are all double windows, 

 the outer windows being hinged at the top, the inner ones 

 hinged at the bottom, so that they may be opened as shown 

 in plan (111. 18). The space beneath the roof is not ceiled in,, 

 the portion between the rafters and tie beams being left open 

 so that the air from the windows may be deflected up against 

 the roof. In such a building the windows may be left open on 

 both sides of the building, affording excellent ventilation and 

 at the same time not permitting any direct draught to blow 

 upon the machines. The large door in the end of the building 

 is provided with double doors, the inner one having ventilating 

 holes as shown in 111. 18. The house is 59 feet long by 21 feet 

 wide and 7 feet 6 inches from the floor to eaves, inside measure- 

 ment. The floor is made of cement or hard packed gravel. 



The dark room is 6 by 8 feet and is ceiled up with matched 

 boards to the rafters. It is provided with a wide door, which 

 for purposes of ventilation is best made of a stout frame cov- 

 ered with burlap or bran sacking. In one end of the room.
