Abstract
Apparatus for the precision cutting of lumber from logs by an attached chain saw, the apparatus comprising a frame, a rectilinear guide member mounted upon the frame, and a carriage mounted for longitudinal movement along the guide member. The carriage carries a chain saw adjustment control assembly which may be laterally set to precision cut slabs of a predetermined thickness from a log; which may be vertically set for cutting through logs of varying thickness; and which may be angulary set for greater cutting efficiency of the log. Log jacks and log dogs attached to the frame to prevent movement of the log relative to the frame may also be provided. The carriage may further be provided with a winch for pulling the cutting bar of the chain saw through the log.
Claims11
Lumber making apparatus for the cutting of wood by an attached chain saw comprising:
- a frame;
- a longitudinal guide member mounted on said frame;
- a carriage mounted on said guide member, said carriage adapted to travel to and fro on said guide member;
- and
- a chain saw adjustment control assembly mounted on said carriage, said control assembly including shaft means rotatably and laterally slidably received in said carriage, said shaft means including chain saw attachment means adjacent a terminal end thereof;
- first lock means operable to secure said shaft in a laterally selected position;
- and second lock means operable to secure said shaft in selected rotational position whereby the cutting bar of an attached chain saw may be rigidly secured at a preselected angulation and lateral position relative to said carriage.
Lumber making apparatus for the cutting of wood by an attached chain saw comprising:
- a frame having at least two standards;
- a rectilinear guide member horizontally mounted on said standards, said guide member including opposing planar surfaces;
- a carriage including a plurality of rollers firmly engaging the planar surfaces of said guide member for transporting said carriage longitudinally along said guide member;
- and
- a chain saw control assembly mounted on said carriage, said control assembly including a shaft journaled for rotational movement and lateral movement relative to said guide member in said carriage;
- and means for attaching a chain saw to said shaft;
- and means for locking said shaft in a preselected lateral and rotational angulation whereby an attached chain saw may be positioned laterally and to a desired depth and cutting angle relative to said guide member.
