  • Patent number: 5107665
    Abstract: A spatial guide adapted to be affixed to a gasoline-powered line trimmer (also called a string trimmer) to serve as a stand-off device, such that the cutting head of the trimmer cannot come any closer to an obstacle than is permitted by the length of a rigid arm. A rigid block of material having a central bore is configured to be attached to the trimmer's tube near the cutting head. The rigid arm attaches to the block of material, preferably by use of the same fasteners that hold the block to the tube. A slot in the arm permits selective adjustment of the distance by which the arm protrudes in a cantilevered manner from the block and hence from the tube. A large roller is mounted at the distal end of the rigid arm and serves to foster sliding and/or rolling movement between the arm and any obstacle adjacent which vegetation is to be cut--as the cutting head is manually moved past the obstacle.

  • Patent number: 5048778
    Abstract: An apparatus for holding a trash bag. The apparatus includes base structure having an opening therethrough for allowing the body portion of the trash bag to extend therethrough and having a lip adjacent the opening for allowing the opened end of the body portion of the trash bag to be folded there over; and funnel structure having an opened first end for being positioned within the hollow body portion of the trash bag and within the opening of the base structure and having an opened second end. The funnel structure has a passageway extending between the first and second ends thereof for allowing trash inserted into the second end to pass therethrough into the hollow body portion of the trash bag. The cross-sectional area of the passageway at the second end of the funnel structure is larger than the cross-sectional area of the passageway at the first end of the funnel structure and larger than the cross-sectional area of the opened end of the body portion of the trash bag.
