had put their attention to every other piece of machinery in the world 

 and left the incubator to speculators. 



Millions of weak chicks are put on the market each year that never 

 grow to maturity, all for want of correct incubation. An incubator 

 that has to be adjusted every day or twice a day, and then, in_spite of 

 attention, runs above or below 103, is a poor piece of mechanism in 

 this day and age of inventions. I felt sure that some day a machine 

 would be invented that would take care of the ventilation and moisture 

 problem and hold an even temperature, whether run in the cellar, in 

 the barn, in an open shed or out of doors. A cellar is a damp, foul 

 place for a human being to work in, and I wanted a machine that did 

 not require these expensive, even temperatured cellars and thick wall 

 houses. Poultrymen in the past have had to spend as much on the 

 house for their incubators as on the incubators themselves, and then 

 the ventilation was bad. 



Surely a reformation was needed along this line. 



A Wonderful Discovery 



While wrestling with this incubator problem a wonderful discovery 

 was made. This was that a regulator should be attached to the outside 

 of the machine as well as the inside, in order to anticipate any change 

 of temperature on the inside. This outside regulator works in con- 

 junction with the one on the inside and the two keep an absolutely 

 even temperature. 



You see, all the other inventors of incubators have been trying to 

 regulate their machines from the inside and anyone can see that it is 

 the outside temperature that causes variations. So I put my regulator 

 on the outside. The inside temperature of a machine does not change 

 as the outside temperature changes. If the machine is to be regulated 

 from a thermostat on the outside, then the temperature must vary 

 before the regulator can work. The inside of a machine is a poor place 

 for a thermostat, for it cannot work with accuracy. Anyone can see 

 that the inside temperature only changes with that outside. 



I also have a thermostat inside to take care of the animal heat that 

 arises from the eggs as incubation proceeds. This is connected with 

 the one on the outside and the two work in conjunction on the flame 

 at the lamp. If the outside temperature lowers the least the flame is 

 increased to take care of it. If the inside temperature tends to raise 

 from the animal heat the flame is lowered accordingly. Only juet so 

 much flame as is needed is used. The gates on the flame open and shut 

 with the variations of temperature and can never clog up as those 

 sleeve devices sometimes do. These gates tend to create a gas from 

 the oil so that the wick is not consumed and complete combustion and 

 a very hot flame are secured. So absolutely delicate is this regulating 

 device that when once set the thermometer can be taken out and the 

 hatch run through successfully. When the doors of the machine are 

 opened to turn the eggs the flame immediately comes up to take care 

 of this variation so that in a very few minutes after eggs are turned 

 the temperature is back to normal.
