Vintage Machinery entry for William Woodworth
Description:
This reissue includes a hold-down roll (a predecessor to the pressure bar) that was not in the original patent. It is widely believed that the Woodworth patent syndicate bribed officials, including members of Congress, to push this illegal expansion of the patent through both the Patent Office and the courts. Woodworth was deceased when this reissued was granted; his son, William W. Woodworth of Hyde Park, NY, was the administrator. See the "Vintage Machinery" web page on William Woodworth for more information.
