160 AN" EGG FARM. 



or nearly level, position, as shown at A, Fig. 73. There 

 is wire netting from x to w and from w to v, which 

 gives light and air, and also permits the feed to drop 

 through when the cylinder is jarred slightly while the 

 box is at the half tilt. The portions of the box at u, v, 

 w, and y are boarded, and to put litter in the box or 



take it out, make v and the 

 wire strip next it in the form 

 of a door, to be hinged to 

 the board, w. The tilt box 

 is supported upon and rota- 

 ted by an axle, 4, of iron 

 pipe, which rests on joists, 

 these being about two feet

ing, so as to give the box 



room to tilt. A row of tilt boxes, each for a separate 

 flock, may be attached to one continuous axle, and all 

 tilted simultaneously, a row of feed cylinders being sus- 

 pended above them to correspond. 



If, for the sake of economy or convenience, a wooden 

 axle is preferred, the tilt boxes may be nailed to a sawed 

 stick 3x3 or 4x4, or larger, according to the number of 

 tilt boxes it is to turn, the stick being rounded where it 

 rests on the joists ; or a straight pole from the forest 

 may be substituted, Fig. 74, and clamped to the box by 

 bolts, #,#, passing through pieces of hard wood, a and c. 

 Clamps consisting of single blocks of wood and two 

 bolts, Fig. 98, may be used to attach small (chick size) 

 tilt boxes to iron axles. The feed cylinder and tilt box 

 are useful for adult birds and for chicks reared artifi- 

 cially in brooders, the size being according to the size 

 of the birds. 



Various other mechanical movements designed for 

 mixing grain and litter together have been tested, but 

 none has been found as satisfactory as the tilt box. A
