<p>This invention attaches to a sawmill carriage, enabling an operator to turn a log carried by the sawmill carriage without having to return the sawmill carriage to a fixed location. The invention includes a log turning hook with positioning guide bar that slides vertically with respect to, and pivots with, a cylinder. As the turning hook with positioning guide bar is lifting the log, the weight of the log is forcing the hook with positioning guide bar to pivot, which rotates the log ninety degrees into position for the next saw cut.</p> |
