ABSTRACT:
A pair of slightly axially spaced and aligned upwardly opening generally semi-cylindrical lower jaws are provided together with an inverted downwardly opening generally semi-cylindrical upper jaw. One arc end portion of the upper jaw is mounted between one pair of corresponding arc ends of the lower jaws for swinging of the upper jaw between a closed position coacting with the lower jaws to define a generally horizontal cylindrical passage and a raised position with the other arc end of the upper jaw swung upwardly and the upper jaw opening in a generally horizontal direction with the upper jaw gravity biased toward the raised position. The aforementioned one arc end of the upper jaw includes abutment structure projecting into the area bound by the lower jaw when the upper jaw is in the raised position and engageable by a tree trunk lowered into the lower jaws to cam the upper jaw downwardly over the tree trunk. The other arc end of the upper jaw, when the latter is in the closed position, is snugly received between the other ends of the lower jaws to limit lateral deflection of the upper jaw other arc end and the jaws include opposite axial end tree trunk limb stripping edges.
