mounted with a -winch reel, which is always placed behind every dye-beck. After 

 wincing in this, the pieces are fastened together again, and put through the washing 

 machine two or three times ; they then are ready for the subsequent operations. 



Another method of dyeing is now adopted by several printers, termed spiral-dyeing. 

 In this process 30 to 40 pieces are left stitched together, entered into the dye-beck at 

 one end, and caused to revolve spirally through the liquor and over the wince from 

 end to end of the beck ; the end which was entered first is now passed through a porce- 

 lain eye, brought back across the face of the beck, and knotted to the last end of the 

 eet of pieces, after passing through another eye which directs the cloth into the dye 

 beck again. The process is now continuous, and the pieces constantly moving from 

 end to end and back again, pass through all parts of the dye-beck, and are all sub- 

 jected to the same heat. It is said that much greater uniformity of dye is obtained 

 by this method. Figs. 378 and 379 show the spiral or endless dye-beck of Mather 

 and Platt A, cast-iron dye-beck; B, fixings for carrying wince ; c, winces; D, cloth 

 being dyed ; E, spur wheels, and catch boxes, &c., for driving ; F, driving shaft ; o, 

 handles and tappet shafts for putting in motion or stopping the wince ; H, steam- 

 valve ; r, steam-pipes ; x, perforated steam-pipe passing through the beck ; i,, mid- 

 feather ; H, peg-rail for keeping the pieces from entangling. Messrs. Mather and

Platt have recently introduced a double-cased dye-beck, for which they claim the 

 following advantages : 



1st. Having neither internal steam-pipe, nor midfeather, there is no possibility of 

 tearing or damaging the goods in the process of dyeing. 2nd. As no steam is ad- 

 mitted to the dyeing solution, its strength is maintained uniform, and, in fact, rather 

 increased to the end of the operation. 3rd. Perfect freedom from stains is insured. 

 4. The work is more regular, and effected at less cost of material than with becks, to
