ABSTRACT:
A planing machine is provided with a height retention mechanism for a cutter carriage, and includes a machine base, a plurality of upstanding posts, moving means, and a sector plate. The posts extend upward from the machine base. The cutter carriage is disposed above the machine base, and has opposite end portions mounted movably on the upstanding posts for sliding movement of the cutter carriage along the upstanding posts. The sector plate is mounted rotatably on the machine base about a horizontal axis, and has a stepped top face formed with a plurality of steps, which are at different elevations relative to the machine base. A regulating rod extends downward from the cutter carriage above the stepped top face. The sector plate is rotatable about the horizontal axis to align the regulating rod with a selected one of the steps and to enable the regulating rod to contact the selected one of the steps and stop further movement of the cutter carriage toward the machine base, thereby retaining the cutter carriage at a desired height relative to the machine base.
