  • Patent number: 5511315
    Abstract: An attachment for a chain saw is provided for adapting the saw blade to cut small diameter branches without weakening the saw blade holder or causing undesired kickback or jamming. The attachment comprises a pair of L-shaped cutting bars attached on both sides of the saw blade holder and spaced sufficiently apart to accommodate the width of the cutting chain. The cutting bars comprise a support portion and an angle portion, the support portion positioned approximately midway along the length of the saw blade holder and extending along a line parallel to the longitudinal axis of the saw blade holder. The angle portion of the cutting bars projects beyond the lower edge of the blade, and forms a wedge shaped angle or bight between the saw blade attachment and the cutting chain.
