  • Patent number: 6609547
    Abstract: The log splitter of the present invention is interchangeably mounted to a skid loader in the same manner as conventional attachments, wherein the skid loader longitudinal axis and log splitter longitudinal axis are perpendicular. The log splitter has a mounting frame, a H-beam connected to the mounting frame, and a piston assembly and blade connected to the H-beam. The mounting frame has a top lip and a bottom flange. The skid loader has an attacher that engages the top lip and bottom flange of the mounting frame. The skid loader may supply power to the log splitter, so that the piston assembly pushes the head towards the blade. A user controls the orientation of the attacher, and hence the log splitter. The log splitter can pick a log off the ground, the skid loader can move while holding a log, and the log splitter can split a log over a receptacle.

  • Patent number: 6607016
    Abstract: A jig having a guide block and a repositionable clamp for use with a saw for hand cutting tails and pins on the ends of boards to form a dovetail joint. The guide block has four planar sides that are joined to form a substantially square tube, the ends of which define guide faces that form an oblique angle with any plane orthogonal to the planar side of the guide block. A pair of magnets within the body of the guide block, each covered by a low friction pad firmly engage the saw and keep it in contact with the guide faces throughout the cutting operation. The guide block also has two orthogonal wing surfaces for positioning the guide block against a face of a board to orient the guide faces either: (a) square to the end of the board and at an angle to its faces, or (b) square to its faces and at an angle to the end of the board. The repositionable clamp is secured to the guide block for clamping it to the board in either of the two alternative positions.

  • Patent number: 6604562
    Abstract: A tree pusher for safely felling trees. The tree pusher controls and determines the direction in which the tree falls, using a base, a frame, a detachable head which engages the tree trunk, and an extendable screw-type trailer jack that is repairable/replaceable during operation and capable of bearing the weight of a large tree, for urging the frame and the head against the trunk of the tree. For use on uneven ground, the tree pusher is provided with a base extension. A chain is used to connect the base of the tree pusher to the trunk of the tree, to prevent movement of the base when the jack is activated. The tree pusher can be readily moved to the job site, and can be used on any type of terrain, including hard surfaces, and for any type of tree, including trees with rotten wood.

  • Patent number: 6595252
    Abstract: A method of producing the floor-bridging units, which increases production rate of the floor-bridging units. First rough lumber beams are fed through a planer, which planes the lumber to the required consistent size tolerance. The planed lumber is transferred to a cut-off saw to cut the legs. The legs are transferred to a dado machine and a dado slot is cut into the lumber. The legs are transferred to a joining station to form the X member, where the dado slots are joined into a dado joint by gluing and stapling the joint. The X member is transferred to a trimming station to be trimmed. At the same time flanges are being made by cutting sheet lumber in strips and then into rectangles to form the flanges. The flanges are transferred to a nailing jig, while glue is applied to the trimmed ends of the legs of the X members. The X members with the applied glue are transferred to the nailing jig.
