A 19th-century encyclopedia article explaining how looms are built and used. It covers the warp and weft, the loom's essential parts, heddles, the shed, the fly-shuttle and batten, drop-boxes, let-off and take-up motions, and the temple. It then moves to plain weave, twill, double cloth and satin, the Jacquard machine with its punched-card chain, ribbon weaving, and velvet and pile weaving. It is illustrated with numbered engravings (Figs. 2896-2940) and a few small design-paper drafts.
