Cotton weaving: its development, principles, and practice . e it. Hence therehave been invented as aids to this end quite a number ofmechanical stokers of more or less merit. These, how-ever, have not been in the main labour improvementsupon the human manual stoker. They greatly lightenedthe oppressiveness of the stokers labour in relieving him 372 COTTON WEAVING. from direct exposure to the glare and heat of the furnace,and dispensed with the requirement of skill on his part inthe distribution of coal upon the fire. He had only tofeed the hoppers of the stokers, and if he could throw thecoal into them it could not go wrong. The iron arms ofthe stoker did the distribution. Something, however, remained yet to be the furnace could be fed mechanically, why could notthe hoppers ? The inventor again, in the person of Wrigley, the principal manager of the extensivemills of Messrs. Fielden Brothers, Limited, Todmordcn,said they could be, and forthwith proceeded to show how,by the invention of his automatic stoker feeder. The. Fig. 189.—Mechanical Stoker Feeder Conveyor Worm. accompanying illustration, fig. 188, represents a series ofboilers fitted with mechanical stokers, and the mechanicalstoker feeder. Instead of tipping the coal, as usual,into and upon the floor of the fire-hole in frontof the boilers, a series of large hoppers are arrangedin front of them for the reception of the coal, and intothese it is tipped from carts or waggons as the casemay be. The hoppers have vents at the bottom anddischarge into a channel in the floor. In this channel isfitted a large conveyor worm, a short length of which isshown in fig. 189, the revolution of which carries the coalto the end of the fire-hole, delivering it into a small hole,whence it is lifted by an endless chain of buckets formingthe elevator. These discharge it into the longitudinal CONSTRUCTION OF A WEAVING ESTABLISHMENT. 373 half-tube extending along the front of the boilers over thehoppers
