Abstract:
1. A brush and tree limb clearing double chain saw arrangement comprising: two chain saw bars connected at one end to a central hub, each chain saw bar extending in substantially opposite end to end directions away from said hub to approximately double the swath able to be cut by said arrangement; a pair of aligned chain sprockets on said hub mounted side by side on an output shaft driven by a common drive motor mounted to said hub; each sprocket engaged by a respective saw chain recirculated around an associated chain saw bar and sprocket, with one of the saw chain portions when traveling on an upper side of an associated chain saw bar moving towards an associated sprocket and the other saw chain portions when traveling along an upper side of said associated chain saw bar moving away from an associated socket so that both of said chains travel along their respective chain saw bars' upper sides in the same direction; a series of elongated brush and limb capture pieces attached to each of said chain saw bars to project out laterally past said upper side of both of said saw chains, angled back towards the direction from which both of said saw chains move on said a respective chain saw bar upper sides, said capture pieces tending to capture brush or limbs and draw the same against a respective saw chain for cutting therewith when said upper sides of said chain saws are moved broadside into said brush and limbs.
