Part 2 of E. A. Posselt's survey of weaving machinery, published in Philadelphia in 1901 as a supplement to Part I, covering devices that appeared after the first volume. It describes and illustrates, mostly from patents, shedding mechanisms (dobbies, Knowles and Crompton harness motions, leno and selvage motions), shuttle changers and boxes, Northrop automatic loom parts, narrow ware looms, let-off and take-up, stop motions, picking, shuttles, temples, Jacquard and card-cutting machinery, reed tools, winding, quilling, warping and slashing machines, and thread cutters. The text is technical mechanical description keyed to line drawings, aimed at mill managers, designers and students. It contains no weaving drafts.
