| XC-504 | 1855-03-22 | Reuben P. Benton | Toronto, ON Canada | Improvements in machinery for manufacturing waggon spokes and other articles irregular in their form |
US patent {10,662} was granted to R. P. Benton of Rochester, NY, for a “machine for dressing spokes”. It is likely that the Canadian and American patents cover the same machine, and that Mr. Benton was in reality a resident of the USA who pretended to reside in Toronto so he could obtain a Canadian patent (at the time, only Canadian residents could be granted patents.) XC patents are Canadian patents issued between 1824 and 1869.
