The art of weaving, by hand and by power, with an introductory account of its rise and progress in ancient and modern times . eshaft with the wheel H, which drives the wheel I; on the sameaxis with the wheel I, is the drum J, which drives the yarn beamF. The drum J, on which the yarn beam rests, and by which it ismoved, is exactly one yard in circumference, and upon one endof its axis, there is a screw working into small geared wheels con-nected with an index, which indicates the revolutions of the drumduring the warping of each beam, from which the length of yarnon each beam is ascertained, and the attendant is paid accordingly.The axis of the yarn beam rests on two slots of the framing at K, and is pressed down upon the drum J, by the stirrup L L, which isalso weighted down by the cross lever M. From the top of the 334 THE ART OF WEAVIXG. stiiTup L, an arm N extends to the guide reed E. so that as theyarn fills on the beam F, it gradually rises, and the arm N pressesup the guide reed with the same gradual motion, so as to keep italways in a proper position in relation to the increasing diameter of Fig. 151.. the yarn beam: O, Fig. 151, is a strap attached to the weight P, and which winds round a small shaft, on the end of w^hich theratchet wheel Q, is made fast. When the beam is sufficiently full, the strap O is wound up by means of a wrench attached to theratchet wheel, which thereby lifts the weight P, the lever M andstirrup L, until the hook on the axis of the yarn beam at K, is sofar relieved as to be pressed back: the full beam is then removed, and an empty one put in its place—the stirrup is brought forwardtill the hook is above the axis of the beam—the catch of theratchet wheel is lifted—the strap unwound—and the machine isthen ready to warp another beam. WARPING. 335 From the foregoing description, it will be seen that this warpingmachine differs very little from those used in Gr«at Britain. It ishowever in every respect as simple and efficient, besid
