| 50 | Portable sawbuck | US303304 | 1989-01-30 | US4913425A | 1990-04-03 | Gerald R. Anderson |
| A portable sawbuck is disclosed that uses three plates to form both a clamp and a vice. The center plate acts a both a clamp plate and a vice plate. The clamp portion can be attached to trees or any other vertical wood post. Four carriage bolts secure the clamp to the tree or post. The vice extends from the opposite side of the clamp and consists of a yoke and the third plate, which rides on the yoke. A threaded rod, which is welded to the third plate and crank are used to operate the vice. Logs are placed in the vice and are rested on the yoke as the vice is tightened. Once secure, the log can be cut on either end, working toward the sawbuck. Logs can be cut to within inches of the sawbuck. A series of spikes are welded or otherwise attached to the plates to further secure the logs to the vice and the clamp to the tree or post. The spikes also reduce the turning moment placed on the sawbuck as logs are cut. The vice portion can also be used without the clamp by clamping the yoke to sawhorses using " U" clamps. The device is intended to be made in kit form for easy shipping and can be readily disassembled for storage. | ||||||
