arms K, -which terminate in forks, in which fit the spars s ; tho reel is boarded between 

 the spars, as at T. Tho framework o of the two dye-becks is connected by the piece 

 T, which carries the bearings of the short shaft v, on which is keyed one of a pair of 



mitre wheels w w ; there are sliding catch boxes x x, on this shaft, which revolve 

 with it; there are corresponding catch boxes keyed on the ends of the shaft Q ; the 



connecting piece u carries also the pillar 

 p, which carries the bearings of the vertical 

 shafts T, and also of the horizontal shaft 

 z ; keyed on the shafts T and z are bevel 

 wheel a a, and at the bottom of shaft T, 

 the mitre wheel w. Permanent motion 

 being given to the shaft v v, by this gearing, 

 either of the reels can be put in motion or 

 stopped by the catch boxes x x, worked 

 by lever handles, in or out of the catch 

 boxes on the ends of the reels. In work- 

 ing the becks, two pieces are knotted end 

 to end, and each length passed over the 

 reel down between two of the studs N, 

 under the steam-pipe K, up behind the 

 diaphragm L, being then knotted together 

 so as to form an endless web, tho bulk of 

 which lies on the bottom of the beck. The 

 drawing shows a beck adapted for 15 

 lengths of 2 pieces each, or 30 pieces. 

 About 200 gallons of water are put in the 

 beck before the pieces are put in ; and, 

 after the pieces, the dye-stuff is added, the 

 reel sot in motion, and the steam gently 

 turned on; from the steam going in at 

 each end, tho beck is uniformly heated; 

 tho heat is then gradually raised to boil, 

 generally in about two hours, tho pieces 

 continually revolving with tho reel so as 

 to bring each portion successively into 

 the air, agitating the dyeing materials at the same time. 



This gradual heating of the dye-beck was a method arrived at by practice, and it
