Wood planing machine that permits motor-driven height adjustment of a cutter carriage

摘要

In a wood planing machine having rotatable screw rods and a cutter carriage with threaded members that engage the screw rods, a gear mounting seat is slidable along a drive shaft that is parallel to and that is rotatable with the screw rods. Upper and lower driven gears are mounted on the gear mounting seat and are capable of selective engagement with a drive gear on a drive axle of a motor-driven rotary cutter on the cutter carriage. The arrangement as such permits motor-driven height adjustment of the cutter carriage.
