Abstract:
1. A sawmill carriage for use on a sawmill base and with a saw head, comprising: a horizontal base having an assembly which provides planar horizontal movement when fitted onto a set of rails of a sawmill base; a vertical saw support having a horizontal base and extending vertically therefrom; a cross rail attached to a first vertical saw support; whereby the vertical saw support and the cross rail form a rigid frame; a rotate rod extending horizontally from said vertical saw support, said rotate rod being capable of axial rotation; at least one lift cable configured to raise or lower the saw head when said rotate rod is rotated; and a friction winch/brake assembly capable of frictionally imparting an adjustable resistance to the axial rotation of the rotate rod; said saw head being slidably affixed to said rigid frame and affixed to the lift cable such that rotation of the rotate rod displaces the saw head in a generally vertical direction.
