, in 1836 and devised a loom for the manufacture of fancy cotton goods, receiving a patent on 23 November 1837 (U.S. Patent 491). In this loom one part of the warp was depressed while the other was lifted, instead of allowing one part to remain stationary, thus securing more room for the passage of the shuttle. Another feature of it was an endless loop pattern chain, which, with its peculiar apparatus, operated the warp. This allowed many more pattern sequences and made them much easier to change. Crompton went back to England in 1838, and, after patenting his loom there, returned with his family to this country in 1839.
