INCUBATOR AND BROODING HOUSES 



This gives a house entirely free from inside posts and makes 

 possible a view of the whole interior from any part. The hover 

 floor is 3 feet wide (the width of the trench) and in the 3-foot 

 pens the hover top slides on cleats (F) 6 inches from the floor. 

 The top or cover is only 24 inches wide, which leaves 12 inches 

 of the sUghtly warm floor in front of the hover cmtain, making 

 a splendid resting place for the little chicks or ducklings which

they evidently enjoy. When first they are put in the hover they 

 are penned back nearly to this floor and the gentle warmth 

 helps them and keeps the floor free from dampness. The cover 

 being in two parts (A and B) and sliding freely on cleats (F) 

 may be readily abjusted so as to give ventilation at the back, 

 front or center of the hover, or all three, and the surplus heat 

 may escape in the same way. 



The hover floor is kept Httered with chaff or shavings and 

 when the pen is to be cleaned the hover top is removed, the 

 back board which sets between the cleats can be taken out and 

 the litter swept into the aisle and taken thence in barrels. When 

 the little chicks are to be changed from pen to pen, the back 

 boards are taken out and they are driven down the aisle from 

 one pen to another, which in the long end of the house are 4 

 feet wide and the hover 8 inches high, but are otherwise the same 

 as the short end. The illustration shows a hover closed, one 

 with the top partly cut away and one with the top off and the 

 back out, ready for cleaning. 



The hot air is admitted to the hovers through the upright 

 li-inch pipes seen in the lower floor. These pipes reach nearly 

 to the cover of the hover and the bottom ends just reach through 

 the board floor, being flush with the under side. Back of each 

 second hover (on the division post, so as to be out of the way), 

 is a 2 by 3 air box which reaches down under the 2 by 6 side 

 and permits the cold air to enter the trench. This gives a chance 

 for the warm air in the trench to rise through the short, upright 

 pipes under the hover and draw in cold air from the aisle, mak- 

 ing a perfect circulation. The warm air strikes the hover cover 

 and deflecting, makes, a perfectly warm box on all sides of the 

 little chick and yet exposes his body to no direct heat. The 

 variation allowed by the slide cover permits of ventilation and 

 the escape of surplus heat at the will of the operator. In very 

 hot nights the cover may be removed altogether. For the older 

 chicks no curtain is supplied for the hover front, and this ar- 

 rangement leaves the front entirely open in warm weather.

OVERHEAD PIPING SYSTEM 



This brooding house may be built exactly like the one con- 

 taining the underneath piping system described heretofore. 

 The only difference is the arrangement of the hot water pipes, 

 and the necessary difference in the construction of the brooderss. 



JO— SECTIONAL VIEW, SHOWING OVERHEAD HEATING SYSTEM 



In the accompanying illustration the overhead piping system 

 is used. The construction of the hovers is very simple. The 

 back is formed of 1-inch boards 12 inches wide and the divisions 

 between the brooders are made of the same size boards, in which 

 have been bored eight holes to receive the four flow and four 

 return pipes. A narrow board is let in to the division boards 

 2 feet 6 inches from the rear wall of the brooder. To this is 

 tacked the felt which hangs to the floor of the brooder and is 



slashed for the ac- 

 oommodjition of the 

 chicks in passing 

 to and fro. Over 

 the pipes are placed 

 foot-wide boards 

 and resting on the 

 edges of these are
