Description: |
| Francis T. Chambers - patent attorney
My present invention relates to the mechanisms which control the feed or tool and work presenting movements of planing-machines, and it is especially adapted for use with, metal-planing machines, in which the tool is driven by being attached to a carriage that is situated upon, guided by, and moved to and fro along the bed of the machine while the work is held stationary beneath it. The chief object of my said invention is to provide in the mechanism which automatically transmits feed motions to the tool-holding part of such a planing-machine's carriage an improved motional clutch operative to vibrate the main driving-shaft of such planer's feed mechanism in the manner of a rock-shaft, said shaft being further limited in the motions thus imparted to it to a definite angular throw by means of abutting devices ancillary to the clutch aforesaid. Further objects are to contrive said improved clutch mechanism in such manner that it may be actuated in direct connection with the to and fro movements of the planer's carriage along its bed, to associate the mechanism controlling the reciprocations of such a planer's carriage with mechanism secured to the bed of the planer and adapted to impart movement to the planer's feed mechanism upon the reciprocation of the carriage aforesaid by a direct and simple gearing, and by this means to supplement and give mutual support to parts which would otherwise have to be considerably heavier, together with such further objects as will be apparent from this specification taken as a whole.
