. A dictionary of arts, manufactures and mines : containing a clear exposition of their principles and practice. left hand a bundle offlax, lays it transversely across the frame, and strikes it smartly with repeated blows ofthe sword, pushing forwards continually new portions of the flax into the machine. She be-gins with the roots, turns next round the tips, then goes on through the length of the is frequently exposed twice to the brake, with a stove drying between the two ap-plications. The brake machines aflford a far preferable means of cleaning flax than the abovehand tools. The essential part of such a machine, consists in several deeply fluted roll-ers of wood or iron, whose teeth work into each other, and while they stretch out theflaxen stalks betwLxt them, they break the wood or boon, without doing that violenceto the harl which hand mechanisms are apt to do. The following may be regarded as FLAX. 491 one of the best constructions hitherto contrived for breaking flax. Fig. 415 is a viewof the right side of this machine. Fig. 416 the view from behind, where the broken416 415. flax issues from between the rollers. The frame is formed by the two side pillars orwalls a, a, which are mortised into the bottom b, b; and are firmly fixed to it bybraces. Two transverse rods d, d, secure the base, two others d d, the sides. Ineach of these a lateral arm e, is mortised in an oblique direction ; a cross bar /, unites both arms. Fig. 417 shows theinside of the left side of the frame,?with the subsidiary parts. The threerollers g, i, k, may be made of redbeech, with iron gudgeons, and flutedin their length, each of the flutes beingj5_thsof an inch broad, and y^pths large roller g, bears upon theright side, a handle h, which on beingturned, sets the whole train in side partitions a, a, are furnishedwith brasses in whose round holes I, g,fig. All, the gudgeons g work. Forthe extremities of the two smallerrollers, there are at n and e, slots
