Concluding installment of a serialized history of weaving in the journal Engineering (June 25, 1875), covering the early development of the power loom. It quotes Edmund Cartwright's patent specification in detail, including its warp and weft stop motions, take-up and let-off motions, temples, and warp dressing. It then covers William Radcliffe's dressing frame and his 1828 book, Horrocks's picking mechanism, and later inventions such as the Ewart pneumatic loom, barrel looms, Bowman and Woodcroft tappet motions, and the application of the Jacquard principle to power looms. It ends with a note that the series will go on to describe recent and approved machines.
