A short 1847 Scientific American article on a new power check loom invented by Mr. Peacock, agent of Ida Mills in Troy, New York, reprinted from the Mechanics' Mirror. It traces the progress from two-shuttle to three- and four-shuttle looms, including Mr. Neal's revolving shuttle box, and describes Peacock's adjustable single pattern wheel with movable pins that can produce any gingham pattern from two to 220 picks. It stresses the importance of color arrangement and balance in gingham weaving.
