Abstract
A device is disclosed to make slits through the bark of a log with a chain saw. The chain saw has a blade with a chain which runs over its extreme free end which is preferably semicircular in shape. Rotatable guide rollers are mounted on both sides of the extreme end of the blade and are preferably coaxial with the semicircular end. The lateral surfaces of the guide rollers face each other and guide rollers in operation hold the chain of the chain saw in contact with a log to be cut for cutting slits of a given depth through its bark.
Claims20
A kit for making slits in logs, said kit for installation on a chain saw, a blade of said chain saw having a chain for movement along said blade at least at a first end of said blade opposite a motor of said chain saw, said kit, when assembled on said chain saw, for being disposed, in operation of said chain saw, at said first end, and guiding said chain at said first end, whereby in operation, said saw with said kit installed thereon is for slitting at least a bark layer of a round log, said kit comprising:
- two separate mountable means each consisting of a sole member, each sole member having a substantially circular portion and each sole member being directly mountable, one on each side of and abutting said saw blade;
- said two sole members for being mounted substantially opposite one another on opposite sides of and in proximity of said first end of said saw blade, whereby said two sole members each make contact with a round log when said two sole members are mounted on said saw blade and when said chain saw is in operation, at least when said saw is being moved therealong for making a lengthwise cut therein.
