Abstract
A portable, lightweight, reciprocating saw for topping trees and the like has a frame with a clamp for attaching the frame to a tree. The frame has a pair of interconnected sprockets, one attached through a shaft to a detachable, portable power drill, and the other attached at its periphery to a curved blade. As the second sprocket is rotated, the saw blade reciprocates. The reciprocating saw blade is held against a tree top or branch by means of a biased blade guide adapted to move along a guide rail disposed perpendicularly of the frame in one plane and of the tree in the other plane for essentially automated, non-manual operation of the saw.
Claims7
An apparatus for topping trees, comprising in combination:
- frame means having a horizontal and vertical elongate frame member attached together at the respective end perpendicularly of each other;
- a power source detachably mounted on said frame means for providing rotationally directed power;
- drive means attached to said frame means and said power source for receiving said rotational power and translating it into reciprocally directed power;
- elongate saw blade means having a serrated side and a non-serrated side and being attached to said drive means at one end, so that said blade means can be reciprocated;
- blade guide means slidingly attached to said blade means along the non-serrated side of the blade means;
- biasing means attached to said blade guide means and said frame means for applying pressure to said blade guide means and transmitting that pressure against the non-serrated side of said blade means;
- and
- securing means for attaching said frame means to a tree.
