The art of weaving, by hand and by power, with an introductory account of its rise and progress in ancient and modern times . rpose of changing or sheddingthe warps, but they are constructed so as to carry rollers, revolvingon certain bars, as their axles, and adjustable, longitudinally in theirsituation thereon ; which rollers act upon certain vertical levers, andthereby effect the shedding of the warps. But Mr. Clarkes flexible tappet rack, is formed by simply provi-ding a given number of bars or ribs of a certain length, accordingto the number of shafts or headles employed in the loom, or thewidth they occupy, and placing them at certain distances these bars are mounted, in any convenient manner, teeth,tappets, or studs, capable of being readily adjusted, as the differentpatterns or devices to be woven may require ; the whole are formedinto an endless flexible rack or band of tappets, by side bands, belts,or chains, hereafter more particularly detailed. In order that this invention may be more perfectly understood,two modes of applying the improvements are shown in the figures. Fig. 184. ^^ ^^,. FANCY WEAVING. 397 Fig. 184, is a front view of a power loom, representing the appli-cation of one description or arrangement of the improved endlessbelt or chain of tappets to a loom for weaving figured fustians ; andFig. 185, is a side elevation of the same. The ordinary framingor loom-sides, are shown at A A, supporting the warp roller B, fromwhence the warp threads C, proceed through the headles D, alsothrough the reed E, (see Fig. 184) of the vibrating lay F, () over the breast beam G, to the cloth roller H, as usual. Theordinary crank shaft of the loom is shown at I, from which motionis communicated to the improved mechanism, attached to the sideof the loom, and supported in a separate framing a a, as follows:— Fig. 185.
