Heated Colony Brooder-House as the result of a long test. It has been 

 found to be better than the ten or twelve other types of burners used 

 because it gives a cone-shaped blaze that is directed up into the radiator 

 where it is needed instead of being sent out in jets at right angles to the 

 burner. It gives more complete combustion than the cap type of burner 

 and is capable of a wider range of temperature, that is, it can be turned 

 very low for use in mild weather; or will give a flame sufficiently large 

 to maintain the proper temperature under the hover when it is 10° to 

 15° below zero outside. Burners with more than one control valve are 

 to be avoided. Among the burners tested there were a number which 

 had two or three wheel valves and in addition to these a needle control 

 valve. This type of burner is undesirable because it is too complicated 

 for the busy poultryman, is likely to get clogged and upon trial does not 

 prove to be so satisfactory as the burner with only one needle control 

 valve. Fig. 71, shows seven representative types of burners tested, six 

 of which were found to be unsatisfactory. 



Fig. 70 illustrates the two principal types of burners. No. 2 is the 

 Dangler burner and gives a pointed, cone-shaped flame very much like 

 a Bunson burner; No. i is the Omaha* burner. It is a cap burner and 

 sends the flame out in small jets at right angles to it. It was found that 

 a great deal of heat was wasted because it was not directed upward into 

 the radiator. 



Fig. 62 represents the heater. (BB) is the burner box, which slides 

 under the house through the rear runner, working on the principle of a 

 table drawer. (Fig. 'J2)-^ (S) is the stem, which telescopes over the 

 collar on the burner box and conducts the heat up into the radiator (R), 

 where it circulates upward and over the diaphragm (see Plate I), and 

 out of the vent pipe (V. P.). (C. G.) is the chick guard which fits in 

 the hole made in the floor of the house. (Fig. 63.) This prevents the 

 chicks from coming in contact with the stem (S) and serves as a passage 

 for bringing the warmed, fresh air into the hover, f

 existing patent as far as we know. Any person or manufacturer is free, so farao 

 we are concerned, to use these plans but must assume all risk of litigation on 

 account of alleged infringements. 



This system of brooding by the use of gasoline-heated colony houses is given 

 free to the public with the request that credit shall be given by manufacturers 

 by placing the following statement on all heaters which they make.
