machine cylinder ; B, the roll of white cloth, and cloth passing through tho machine, 

 and hot room, and being plaited down ; c, tho blanket ; D, the roll of groy cloth, and 

 grey cloth passing twice through the printing-machine, and then through the wetting 

 machine ; E, a wooden roller working in a water trough ; F, water trough, with a 

 stream of water kept running through it ; o, shell upon which the grey cloth is wound 

 after passing through the water ; H, gallery above the machine where the printed cloth 

 is plaited down ; i, platform for putting up the grey rolls. Mr. Furnival of Haslingden 

 has introduced a machine for washing India-rubber blankets: fig. 355 is a longitudinal 

 section, 356 a plan, 357 is a sido elevation, and 358 a cross section. A, an iron cistern 

 containing water, and forming tho framework of the machine ; B, circular brushes, 

 with a pulley keyed on the end of each ; these brushes are turned by a strap from tho

main driving-shaft c, through the carrier pulley D, bya strap as shown in the dotted 

 line B, so that the brushes may revolve in opposite directions ; F are squeezing rollers 

 of brass or wood, also turned by a strap from the driving-shaft c. Clean water is 

 supplied to the machine by being spirted upon the blanket before entering between 

 the squeezing rollers F. The blanket on leaving the printing-machine charged with 

 waste colour, enters into the machine and is passed through, as shown by the lino o, 

 under and over the adjustable guide-rollers o, and is brought into contact with the 

 revolving brushes, and leaves the machine by the squeezing rollers F ; it is then dried, 

 and returns again to the printing-machine. 



The thickening of mordants and colours is a subject of very great importance to 

 the printer. It is obvious that a mere solution of salts or colouring matters, such as 

 used in dyeing, cannot be used in printing a pattern ; capillary attraction speedily 

 causes such a solution to spread beyond the limits of the pattern, and nothing but
