at c. The ends 10 and 12 of the pipes a are 

 thrust or telescoped into their connecting 

 elbow 8 and their couplings 9, as shown in 

 Figures i, 3, and 5. All the horizontal pipes, 

 except the drip pipe b, which runs toward the 

 side wall of the silo B, are perforated on their 

 under side with holes about one-fourth of an 

 inch in diameter, and about six inches distant 

 from each other, as seen in Figures 3 and. 5; 

 the ends 10 of the pipes a are each held in 

 position by a small wooden peg or pin , as 

 shown in Figures f, 3, and 5. 



A T-coupling f is screwed on to the project- 

 ing end of the drip pipe b, and the vertical pipe 

 g is screwed into the upright branch of said 

 coupling f; the vertical pipe g affording an 

 outlet or means of escape from the silo for the 

 air and gases. The pipes a a, which extend 

 transversely across the centre of frame A, 

 from side to side, are screwed into the coup- 

 lings 9, 9 and z, the downward branch of the 

 latter coupling fitting loosely within the up- 

 turned end of the drip pipe b. The water, 

 juices, etc., from the forage, are drawn off 

 when desired through the drip pipe b, the outer 

 end of which is provided with a stopper k; 

 but a faucet may be employed instead of the 

 stopper, if preferred.
