Description:
Loom Heddles Patent Model
Patent No. 1,498, issued on February 26, 1840
John Thorp and William G. Angell of Providence, Rhode Island
These heddles, both wire and twine, were exhibited in the Patent Office in a round wooden frame. In the patent specification, Thorp and Angell described the dimensions of heddles for use on a common power loom. A chain of the heddles was formed by taking two pieces of wire or twine and tying them with a common square knot, “which will unite them in the same way and manner that a lady ties her apron strings or a child his shoestrings.” The placement of the knots resulted in the formation of the eyes of the heddles, which raise and lower warp threads in weaving cloth.
Thorp and Angell did not include a patent drawing with the specification. The 1841 Journal of the Franklin Institute remarked of this omission: “We must suppose . . . that the description, although to us somewhat obscure, would be clear to a professional weaver.”
