Stock for holding the cutters in rotary planing-machines.

Ivers Gibbs |
Worcester, MA |
Extended 7 years, and reissued shortly after the extension kicked in.
Innovation is primarily the fact that the stock is hollow. The reissue clarified that the shape of the stock is designed to minimize air resistance. This patent cutter arm was seen in an 1869 catalog from R. Ball & Co., which makes it very likely that it was also manufactured by that company's predecessor, Ball & Williams (active 1858 to 1865). It seems as likely as not that R. Ball & Co.'s successor, Witherby, Rugg & Richardson, also manufactured this arm but we do not have confirmation. |
