The art of weaving, by hand and by power, with an introductory account of its rise and progress in ancient and modern times . ached, will beseen a series of small holes, and it is by connecting the rod I, to anyone of these holes, either nearer or further from tiie fulcrum of thebell-crank lever H H, that the amount of vibration of the take-uplever J, is determined, and either greater or less amount of warpyarn is delivered from the beam after each vibration of the lay, ac-cording to the nature of the fabric to be woven. From the foregoing explanation, any practical power loom weaverwill have no difficulty in comprehending the improvement. Figs. 165, 166, 167 and 168, represent an improved power loomfor weaving light textures, invented by Araassa Stone, an extremelyingenious mechanic of Johnstone, Rhode Island. By means of thisimprovement, whenever, from the accidental breaking or non-delivery of the weft, the striking up of the reed meets with little orno resistance, the delivery of the warp, and also the taking-up ofthe cloth, is suspended, although the general evolutions of the loomcontinue. Fiff. 165. Z^. Fig. 165, is a side view of the loom, with the novel parts at-tached, and in working order; Fig. 166, is a profile representationof the same, showing particularly the novel parts; Fig. 167, is avertical section, taken through the loom at right angles to Fig. 165, PLAIN WEAVING. 357 in the line looking toward the cloth beam; Fig. 168, is a verticalsection, also at right angles to Fig. 165, in the line looking in theopposite direction, that is, toward the warp beam; and No. 30,Fig. 167, is a horizontal view of a portion of the lay of the loom,taken at that end where the improved parts are connected ; therespective letters of reference pointing out the same parts in all thefigures. The yarn beam A, is mounted on the side framing of the loomin the usual way. From this beam the warp threads pass overa whip roller B, above, and thence through the headles C, C,and ree
