Description: |
Francis T. Chambers - patent attorney
My invention relates to feed-clutches used for feeding the tools in machines such as planers, and it is especially, although not exclusively, adapted for use with planing-machines in which the tool is carried on a carriage-which moves to an fro upon the bed of the machine while the work is held stationary beneath it. The object of my invention is to provide an improved frictional feed-clutch which will rotate the main driving-shaft of the feed mechanism alternately in opposite directions, releasing it promptly at the proper times and relieving the driving pressure of the clutch.
