1837 Mason's Patent Model of a Loom Temple

Self-Adjusting Loom Temple Patent Model
Patent No. 291, issued July 22, 1837
Samuel P. Mason of Newport, Rhode Island
Temples are attachments on looms designed to keep the cloth at a uniform width during weaving. Self-acting temples required no adjustment as the cloth was woven, for they automatically adjusted their position. The greater speed obtained with power weaving made the use of self-acting temples a necessity.
The basic construction of Mason’s temples was similar to others of the period. The patented feature of his temple concerned the arrangement of the parts by which the jaws or forceps were forced open and released their hold on the cloth.
Mason patented other useful textile machinery. Notable were an 1830 speeder for roving cotton (a speeder is a machine used in cotton yarn spinning that inserts a twist to the yarn and winds it on the bobbin) and a cotton whipper (a machine that separates clumps of cotton) in 1834. James Montgomery, in his 1840 edition of “Cotton manufacture of the United States Contrasted with that of Great Britain,” wrote that he considered the whipper the best, cheapest, and simplest that he had seen in factory use over a span of thirty years.
