Vintage Machinery entry for Woodbury Patent Planing-Machine Co.
Description:
This was an extension of patent CA-3,433 for an additional 5 years. The extension was filed for by the deceased inventor's executors, and the whole thing was a scheme to extort royalties for a very old idea, the planer pressure-bar. See the VintageMachinery.org entry on Joseph P. Woodbury for more information.
