Description:
Abstract:

The object of the invention is to provide a new and improved friction driving device for shaping, planing, and other machines requiring a reciprocating movement of the head bed-plate, bed, or the like, the device being arranged in such a manner as to insure rotation of the driving-shaft in either direction without shock or jar when changing from one motion to another and without danger of injury to the working parts.

This patent is an improvement to the Manville/Ballard patents used on the Friction Shapers and Planers. The surface of the Friction is grooved and a different type of friction arm (spoke) is used. The original Friction drawing is dated February 22, 1895, which would indicate that the prototype (or sample as Hendey called it) would have been operating and under test sometime during 1895. Since the patent was filed on December 20, 1897, it is fair to assume that the basic design was refined during the 1895-1897 period. This Friction Drive design was used on all Friction Shapers until the last one was built on June 15,1920 (a 15 inch model). (This information courtesy of Hendeyman)
