An encyclopedia article on the loom, tracing its development from the basic warp-and-cloth-beam frame through bobbin, treadle, shuttle, draw, Jacquard and power looms. It explains the parts and operation of the hand loom and the simple power loom, and covers Kay's flying shuttle and drop box, Cartwright's power loom, the Northrop automatic loom, and the Jacquard attachment. Four line drawings illustrate the hand loom, power loom, Northrop loom and Jacquard mechanism, and a bibliography of weaving and loom-construction works ends the article.
