  • Patent number: 5054278
    Abstract: Enhancement of the operability of a long-handled tool by mounting a wheel on an axle with a plurality of sleeves, which can at least partially encompass the axle; the sleeves are displaced from one another and are connected to sleeves on the handle of the tool; the connectors can be variably positioned with respect to the axle, which can be stabilized by a supplemental weight and include opposed and rotationally mounted wheels; in operating the tool with increased efficiency, the wheel is raised to control the operation of the tool at the end of the handle opposite the position where force is applied.

  • Patent number: 5017080
    Abstract: A hand truck for lifting and transporting objects. The truck includes an elongated frame attached to a wheel assembly. A carriage is mounted on the frame to travel the length of the frame. The carriage includes a load bed that extends across the frame, and at least one protrusion located below the load bed that extends above the load bed. A seizing arm is pivotally attached to the carriage above the load body and has a seizing arm with a grip point directed toward the load body. The seizing arm has a stem that extends beyond the pivot point attachment opposite the seizing arm body. A winch with cable are attached to the top of the frame. The free end of the cable is attached to the seizing arm stem. Retracting the cable causes the seizing arm to pivot so the grip point is forced against as object located on the carriage. The force of the seizing arm is sufficient to secure the object between the grip point and the carriage.

  • Patent number: 4637769
    Abstract: A carrier for lifting and transporting a log. The carrier includes a wheeled frame, a hook, and a load stabilizer. The hook has, at one end, a hinged attachment to the frame, and, at the other end, both a point for gripping one side of the log and a point for prodding logs into position. The load stabilizer is movably attached to the frame. After a log is initially gripped between the hook and the frame, the stabilizer is moved into a position in which the stabilizer applies a force to the log to hold the log against the hook and thereby prevent the hook from losing its grip on the log.
