Description:
This patent made the early Hendey Planers and Shapers a commercial success and was the one that David Ballard improved upon. (Patent #310,774) (This information courtesy of Hendeyman)

Abstract:

I do hereby declare that the following is a full, clear, and exact description friction-clutches; and it consists of an elastic reverse-lever working a friction-clutch on the main shaft of a planer or other machine depending on reversed motion, between two driving-pulleys, with corresponding friction-bearings running in opposite directions. The object of my invention is to secure safety against breaking parts of the machine by the failure of the friction-clutch to leave the driving pulley and to secure prompt action in the engagement of the clutch with the reverse-pulley, thereby avoiding the stoppage of the machinery when it is to be reversed.
