Chain saw tree-felling apparatus

Claim 1

A tree-felling apparatus comprising in combination: a. an endless saw chain, b. a saw bar member disposed within the periphery of said endless chain and functioning as the main supporting member for said chain, c. a trackway for said endless saw chain disposed around the periphery of said saw bar member, d. means for intermittently driving said chain around said trackway, e. said saw bar member being pivotally mounted upon a support member that is in turn adapted to be pivotally connected to a wheeled vehicle so that the support member can be pivoted through a vertical arc and about a horizontal axis, f. said support member including a jaw member, g. means for moving said saw bar member through a limited arc about its pivotal mounting so that said saw bar member can move toward and away from said jaw member, h. said saw bar member having a leading edge and a trailing edge, the leading edge being disposed immediately behind the portion of the saw chain that is closest to said jaw member and the trailing edge being disposed directly rearwardly of said leading edge, e. the cross-sectional configuration of said saw bar member and any parts joined thereto in the area between said leading edge and said trailing edge being at least partially wedge-shaped, j. whereby, as said saw chain cuts into the trunk of a tree, and the saw bar member follows into the cut so made, the wedgeshaped cross-sectional configuration of said saw bar member will assist in the directional felling of the tree.
