Machine for manufacturing wooden troughs

Samuel T. Field |
Worcester, MA |
According to the 1873 "Subject-matter index of patents for inventions issued by the United States Patent Office", this patent was granted an extension.
According to an article in the 1859-08-13 Scientific American, "The inventor has the machine in use, and makes a great number of all its various productions, and those persons who feel interested in the invention can obtain any further information upon addressing Messrs. Holt, Field & Bros., Worcester, Mass." This is not exactly a smoking gun that Holt, Field & Bros. was manufacturing this machine, but the fact that the patent was extended makes it likely that someone was manufacturing it. |
