<p>A log clamping apparatus for use in holding half round or stay logs in a cutting operation. The apparatus comprises a rectangular bar rotatable about a rotational axis parallel to the major axis of the bar. The bar has at least one fixed toothed element and one moveable toothed element extending from one narrow side of the bar. The toothed elements face each other and are adapted to extend into axial grooves in the log. Shafts are connected on opposite wide sides of the bar and are each connected to toothed dogs. The shafts are rotated by drive means to pivot the dogs to further clamp the log.</p> |
