By 1922 the Structo Manufacturing Company (founded in 1912) was manufacturing two all-metal looms painted in black and blue enamel. One wove a 4" wide cloth and the other 8" wide. The looms were marketing to people convalescing "to produce much art work" and to "Little Sister and Big Sister too."
The looms came complete with an instruction manual, pattern charts, warp, four shuttles, a draw-in hook and a wrench. Some of the parts of the frames of the metal looms were directly evolved from some of the Structo building sets.
Well-know weaver Mary Meigs Atwater wrote the "Manual of Instructions for Structo Artcraft Looms Numbers 240, 420, 600" in 1930. She also hand-drafted at least 23 weaving patterns for use on the various models of Structo Looms.
By 1932 Structo had filed six new loom patents, including the steel hexagonal warp beam and the pre-filled warp spools. "We perfected this year a method of supplying warp on individual spools for use on these looms which simplifies their use and we shop thousands to our loom users throughout the country."
Ten different models were offered for sale by Structo in 1941. But World War II was to have a huge impact on Structo. Following the company's sale to another company, the loom life was bought by Dick Blick Art Supplies of Galesburg, Illinois in 1972. Dick Blick sold looms through it's catalog through 1978 and still retains the rights to their manufacture.
