Recent Patents. To STEPHEN WILSON, of Streatham, in the County of Surrey, Esq. in consequence of his own Discoveries, and Communications made to him by Foreigners residing Abroad) for certain Improvements in Machinery for Weaving and Winding. [Sealed 31st May, 1823.] THE first subject of this patent, (viz.) the machinery for weaving, is an improvement upon the very ingenious French loom for producing figured goods, described in our second volume, page 95, under the title of Francis Lambert's patent for "mounting and producing, and also removing, preserving, and replacing the figure in weaving, &c.," and which invention is further detailed under the patent of Stephen Wilson, page 255, of the same volume, for" certain improvements in machinery for weaving, &c." By referring to these inventions, it will be seen, that a series of pasteboards pierced with holes, to answer the draft of a certain devised pattern, are successively brought against the ends of a series of horizontal needles, for the purpose of shifting these needles, and thereby causing certain of the rods connected to the necking of the harness to be removed from the lifting bars, so as to vary the parts of the warp or chain threads raised at every throw of the shuttle, and by that means to produce the desired pattern or figure in the loom. The present invention is a considerable improvement and simplification of the above plan, as by this new arrangement, the lifting bars heretofore employed in raising the warp, and also the guide needles, are altogether dispensed with. Plate I, fig. 1, represents the machine in perspective; it is intended to be placed upon the top of the loom, and the lines a a are a series of cords connected at bottom to what is called the necking of the harness, by which the warp threads are drawn up; b b, are the lifting rods, severally hooked to these respective cords; c, is called the axe carré, a revolving box pierced on each side with a series of holes corresponding in number and position to the top ends of the rods bb. An enlarged representation of a portion of the rods, hooks, and their appendages, is shewn in fig. 2. These rods and cords pass through small holes in the several guide plates, d, e, f, g, which answer the purpose of what is called the comber board in other figure looms; e is a frame holding two thin metal plates, laid upon each other in close contact; these plates are both of them pierced with a series of oval holes corresponding. Upon each of the rods b b two small beads are soldered, the holes in the plates e being sufficiently large to permit the upper beads to pass through; but in order to prevent this during the general movements of the apparatus, the |
