The log saw clamp of the present invention includes a brace and at least one jaw connected to an actuation member. While the clamp can be arranged in any number of orientations, the preferred embodiment has two jaws supporting the logs from below, a brace restraining logs within the clamp from above, and an actuation member on either end of the brace. The diameter of the log receiving area in the clamp can be adjusted by moving the actuation members. Preferably, linear movement of the actuation members causes the jaws to rotate and the brace to translate, thereby increasing or decreasing the diameter of the log receiving area. The jaws rotate about a pivot point and are preferably connected to the actuation member via respective jaw mounts. The actuation members are preferably moved with a turn wheel and gear assembly. The turn wheel lets the machine operator adjust the diameter of the clamp a safe distance from the sawing operation. In operation of the preferred embodiments, the clamp is set to a desired position and can apply a constant pressure (if desired) upon a log in the clamp. The brace can be spring loaded to be responsive to slight differences in log diameters. The jaws can have a specialized connection feature to enable quick substitution of the jaws for differently-sized logs. The clamp is preferably substantially rigid, making the clamp more durable and allowing the clamp to apply relatively high clamping forces if desired. |
