  • Patent number: 5467532
    Abstract: A hedge trimmer aid including a reference indicator similar to a bubble level wherein an included air bubble is replaced by a small sphere of lower density than a surrounding fluid provides a true horizontal reference, an adjustable pointer with magnifier which is manually set to a particular angular disposition substantially equivalent to the desired angle of the finished trim, and a frame which couples the pointer and the horizontal reference indicators and furthermore affixes the hedge trimmer aid to the static housing portion of a hedge trimmer in clear view of an operator. In use, the angular disposition desired for the hedge is selected and set by rotating the adjustable pointer to a fixed marking disposed upon the surface of a hemispherical bubble level. The hedge trimmer is then manually rotated about a horizontally disposed axis until the colored sphere within the level and a magnifying sight disposed upon the adjustable pointer are in alignment.
