  • Patent number: 8836529
    Abstract: A chain saw hazard warning light and method for using same. A pair of oppositely-directed light sources emit light beams throughout a chain shot hazard warning zone through rectilinear, slotted openings at opposite ends of a housing. The light beams turn on, if and only if, the cutting chain is rotating about the chain guide bar; alternatively, initiation of rotation of the cutting chain is delayed to permit the light beams to turn on some time prior thereto. The zone is defined by first and second pairs of planes that diverge in opposite directions from the chain guide bar, said planes being disposed at equal, acute angles (most preferably 15°) to, and on opposite sides of, a plane that includes the chain guide bar.

  • Patent number: 4090540
    Abstract: A framework mounted on a tractor has separate vertically adjustable feet to support it from the ground at a desired angle of tilt so that a circular saw, slidable on the frame and driven from the tractor, can be moved downwardly and forwardly to sever a tree along a slanting plane below ground level. The frame has a member engageable with a side of the tree to resist the tendency of the frame to move laterally due to reaction from the cutting load on the saw. A hydraulic motor advances the saw while the tractor remains stationary.

  • Patent number: 4058038
    Abstract: An apparatus capable of detaching from a body of a material such as hay a portion thereof which then can be transported to a desired location. A prime mover such as a tractor carries at one of its ends, for example, a frame which supports a cutting structure capable of cutting into a body of a material such as hay in such a way as to carry out a slicing action while cutting into the body, so as to detach from the body a portion thereof which then can be transported to a desired location.

  • Patent number: 4044979
    Abstract: Hedge trimming apparatus including a substantially horizontal platform pivotable along one edge of a base to level the apparatus relative to a hedge to be trimmed. Wheels and a handle are connected to the base to form a movable carriage for the apparatus. A vertically adjustable column on the platform and a horizontally adjustable shaft mounted on the column are provided to mount a bracket for retaining an electric hedge trimmer on the apparatus, whose position can be adjusted relative to the hedge by adjusting the position of the column and shaft, once the platform is levelled.

  • Patent number: 3931676
    Abstract: A portable power saw apparatus is disclosed having an endless saw chain driven about a bow bar by an internal combustion engine. The apparatus includes a pair of transversely spaced legs respectively secured to the chain guide adjacent the outer end thereof and extending downwardly therefrom. The legs provide a ground-engageable abutment to support the outer end portion of the chain guide and saw chain, and they also define a size guage determinative of the largest diameter object acceptable between the legs for severance by the saw chain. Skid means secured to the handle structure of the apparatus is oriented at substantially the same elevation as the legs and forms a ground-engageable means therewith to support the saw apparatus in a generally horizontal orientation in certain operating modes.
