Tenterhook Willow with Box Feed and Dust Cage.—In orderto render the working of the machine independent of the carebestowed by the attendant, tenterhook willows are often fittedwith an automatic feed, one type of which, the box feed, isshown in Fig. 214. Here the wool, thrown in through themouth of the box at a, falls on to the lattice creeper, b, and isled to the ascending toothed creeper, c, which carries a portionof the material upwards, the excess being doffed by a swingingcomb, d, leaving a constant quantity to be carried forward inthe teeth of the creeper, from whence it is removed by thedoffing roller, e, and delivered on to the lattice creeper,/, whichfeeds it to the willow. Another novelty in this machine is theprovision of a dust cage, g, which catches the wool thrownonward by the drum, h, and in slowly revolving compressesit into a light fleece, in which form it is taken over by the

Bothvery short fibres and dust are drawn out and removed bythe action of an exhaust fan connected with the inside of thedust cage. This last-named appliance is also advantageousin the case of blending different kinds of wool and woolsubstitutes in the willow, in which event, in the absence ofa dust cage, the different constituents would settle down atdistances from the outlet aperture corresponding to theirvarious densities, and thus partly nullify the work done bythe machine. V.—Oiling the Wool. Although the wool is loosened to a considerable degree bythe operation of willowing, especially in the tenterhook willow,the object in view—the separation and isolation of the indi-vidual fibres—is not yet accomplished. This task is carriedout by the carding machine with its energetic working parts,which naturally exert a more decided effect on the wool hairs.Owing, however, to the scaly surface of the very
