214 Description of Messrs. Monteith and Co.'s 



of liquor according to the pattern of discharge. The stop- 

 cocks on the pipes and cisterns containing this liquor, are all 

 made of gkss. 



From the measure-cistern, the liquor is allowed to flow into 

 the hollows in the upper lead-plate, whence it descends on the. 

 cloth, and percolates through it, extracting in its passage, the 

 Turkey red dye. The liquor is finally conveyed into the waste 

 pipe, from a groove in the under block. As soon as the 

 chlorine liquor has passed through, water is admitted in a 

 similar manner, to wash away the chlorine ; otherwise on relax- 

 ing the pressure, the outline of the figure discharged, would 

 become ragged. The passage of the discharge liquor, as well 

 as of the water through the cloth, is occasionally aided by a 

 pneumatic apparatus, or blowing machine ; consisting of a large 

 gasometer, from which air subjected to a moderate pressure, 

 may be allowed to issue, and act in the direction of the liquids, 

 in the folds of the cloth. By an occasional twist of the air stop- 

 cock, the workman also can ensure the equal distribution of the 

 discharging liquor, over the whole excavations in the upper 

 plate. When the demand for goods is pressing, the air appa- 

 ratus is much employed, as it enables the workman to double 

 his product. 



The time requisite for completing the discharging process in 

 the first press, is sufficient to enable the other three Avorkmen to 

 put the remaining fifteen presses in play. The discharger pro- 

 ceeds now from press to press, admits the liquor, the air, and the 

 water ; and is followed at a proper interval by the assistants 

 who relax the press, move forwards another square of the cloth, 

 and then restore the pressure. AVhenever the sixteenth press 

 has been liquored, c^c, it is time to open the first press. In this 

 routine, about ten minutes are employed ; that is 224 handker- 

 chiefs (16 X 14) are discharged in ten minutes. The whole cloth 

 is drawn successively forward, to be successively treated in the 

 above method. 



When the cloth escapes from the press, it is passed between 

 two rollers in front ; from which it falls into a trough of water
