Abstract
A horizontal disc is supported on an arm on a portable saw mill carriage in a plane such that the disc is arranged to follow a horizontal saw kerf to provide vertical stabilization between a log and a carriage. Also a foot is mounted on an arm and is arranged to engage the face portion of a log to provide lateral stabilization. This arm is laterally adjustable for locating it according to the depth of cut. Furthermore, a hold-down wheel assembly is supported on a link which is urged downwardly to provide vertical stabilization between a log and the carriage.
Claims5
A saw mill comprising
- an elongated supporting frame,
- a carriage driven longitudinally along the frame,
- means supporting the frame in parallel relation to a log,
- power driven vertical and horizontal saws on the carriage for producing vertical and horizontal board cuts in a cutting movement along the log,
- a depth gauge and stabilizer on said carriage,
- a foot member on said depth gauge and stabilizer having a face surface,
- said face surface having an inclined leading edge portion facing the cutting direction of said saws,
- an arm integral with said foot member arranged to support said foot member on said carriage with its face surface in slidable engagement with a vertical surface of a log to control the depth of cut of horizontal saws on the carriage,
- gear means on said arm,
- operator control gear means meshing with said gear means on the arm for adjusting the latter laterally for varying the depth of cut of the horizontal saw blades,
- operator control shaft means operating said gear means on the arm for adjusting the latter laterally,
- said operator control shaft means comprising a capstan,
- a line wound on said capstan,
- a vertical gauge having depth indicating graduations thereon,
- a pointer slidably mounted on said gauge in association with said depth indicating graduations,
- sheath means supporting said line for connection between said capstan and said pointer for indicating to an operator the depth of cut of the saw blades,
- and a gauge wheel on said shaft having graduations which further indicate the depth of cut of said saw blades.
