This patent was used on all of the Hendey Friction Shapers until 1915 when the reversing handle design was changed. This device allowed micrometric adjustment of the trip point of the reversing mechanism, allowing cuts to be made to a line. It did for the Friction Shaper what the adjusting screw on the Automatic Stop Rod did for the lathes. (This information courtesy of Hendeyman)


My invention relates to improvements in reversing mechanism of metal shaping and planing machines, its object being to provide what I term a micrometer adjustment, which is applied to the reversing lever for the purpose of adjusting the length of stroke of any shaper or planer which has a reversing lever.
