The American Magnetic was produced by the American Magnetic Sewing Machine Company of Ithaca, New York, ca.1853 - 1854. They were produced under patents issued to Thomas C. Thompson, Samuel J. Parker or Simon Coon. Some examples of the American Magnetic may be marked with the Howe name after Elias Howe brought up infringements of a patent issued to him in 1846.
