Abstract: A tool for the quick and easy installation and tensioning of track assemblies on skid steer loaders is arranged to properly and positively align and draw the free ends of the track together and hold the track ends in proper, aligned condition squared relative to each other for installation of the track link members and tensioning adjustment of the track as may be desired for proper operation of the vehicle. Additionally, this tool can be used to dismount the track by removing the pressure from the pivot bolts, allowing the operator to easily remove the bolts and then gently let the ends of the tracks apart.

Abstract: A vise includes a screw rod extended through an adjustable and a fixed jaw. The adjustable jaw is internally provided with a cam sleeve having a centered cam-shaped bore and two opposite arms outward projected therefrom. The cam-shaped bore is slightly larger than an outer diameter of the screw rod, and provided at one lateral surface with a small length of screw threads. When the screw rod is turned clockwise, it brings the cam sleeve to rotate at the same time while moves in the cam-shaped bore to mesh with the screw threads in the bore, causing the cam sleeve to axially move along the screw rod and finely shifts the adjustable jaw relative to the fixed jaw. And, when the screw rod is turned counterclockwise, it disengages from the screw threads in the cam-shaped bore, allowing the cam sleeve to freely and quickly move along the screw rod.

Abstract: 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 vise is preferably used in conjunction with another identical vise to hold skis securely to a table top or other flat surface while the skis are `tuned` or otherwise worked upon. The skis may be clamped in any desired position, and irrespective of the widths of the skis, the skis may be clamped in position and unclamped with unprecedented ease and speed. A novel, quick-release mechanism is provided on the vise which serves to lock movable jaws of the ski vise relative to each other so as to negate longitudinal travel relative to each other except by rotation of a rod which is at least partially threaded to provide a screw-clamping action.

Each clamp has a fixed and a movable jaw and the two clamps are mountable on the base plate for either a standard 45.degree. cut or for a 30.degree. or 22-1/2.degree. cut in some instances. Guideways for the two clamps or vises are provided on the base plate for coaction with a pivoted clamp adjusting lever and links which interconnect the lever with the clamps so that they may be adjusted bodily in unison and oppositely along linear paths to assure perfect alignment of the mitered ends of molding sections or other work prior to joining by means of nails or glue. Realignment of the joint is also possible if slippage of parts should occur during nailing. It is unnecessary to unclamp the work sections or loosen the movable clamp jaws to effect proper alignment or realignment of the work.
