4 MODEL INCUBATORS AND BROODERS FOR 1909 



and time saver for those who are operating a number of Incubators, 

 as any number can be attached to the same source of supply. This 

 same attachment can be used with the Colony Brooders. It is sold 

 separate from the Incubators and Brooders, and can be applied to 

 many other makes beside the Model. 



The Model Patent Steam Heater. 



The IModel Patent Steam Heating System, new for 1908-9, for 

 large batteries of incubators is both a time and labor saver. The 

 first cost is greater than the ]\Iodel Automatic Filler, but it 

 cut out the filling of lamps, and there is only one central fire to 

 feed to offset trimming the lamps once a day; and the hard coal 

 fuel employed costs much less than coal oil. It is a fuel saver 

 on eight machines up, oil figured at 10 cents per gallon and hard 

 coal at $6.50 per ton, the ruling eastern prices. In other words, 

 it takes a certain amount of coal to keep the fire going whether the 

 heat is utilized or not. The amount of coal consumed in keeping the 

 heater . and eight incubators going does not cost quite as much at 

 $6.50 per ton as it would to run eight incubators with coal oil at 

 10 cents per gallon. Ten to twenty or more incubators could be 

 added to the system without increasing the coal consumption very 

 materially, so that any number added above eight would be heated 

 almost for nothing. This system can be attached to any machine 

 vAth my design of heater, either the Model or my earlier design, the 

 Cyphers, and some others. It not only heats the incubators, but can 

 be arranged to heat the incubating room in cold weather. It is a 

 valuable acquisition to any commercial poultry farm.
