Portable band saw saw mill apparatus
First Claim
1. A portable bandsaw sawmill apparatus comprising an elongated frame, a track extending horizontally along only one side of the frame, a carriage including a support structure, first means for movably mounting the carriage on the track for horizontal movement therealong, a bandsaw having at least two wheels and a bandsaw blade entrained on the wheels, the bandsaw blade comprising a continuous band having transversely extending teeth, the frame including means for supporting a log, means for moving the carriage along the track, second means which cooperates with said support structure for mounting the bandsaw on the carriage so that said bandsaw extends cantilevered therefrom and maintaining a portion of the bandsaw blade which cuts the log in a plane substantially parallel to the frame supporting the log.

Abstract
A portable saw mill apparatus includes a frame carrying supporting wheels, outriggers and a trailer hitch. A horizontal, unitized tubular track is secured to the frame and a carriage is moveable along said track. Mounted on the carriage is a horizontal, cantilevered band saw which is moveable vertically. Logs are received on support members secured to the frame, and the band saw is moved longitudinally of the frame to make successive cuts of the saw. Lowering of the band saw between successive passes provides for spacing of the cuts of the log. A single lever control enables the operator to positively engage or brake the band saw, and also to control the engine throttle.

- 1. A portable bandsaw sawmill apparatus comprising an elongated frame, a track extending horizontally along only one side of the frame, a carriage including a support structure, first means for movably mounting the carriage on the track for horizontal movement therealong, a bandsaw having at least two wheels and a bandsaw blade entrained on the wheels, the bandsaw blade comprising a continuous band having transversely extending teeth, the frame including means for supporting a log, means for moving the carriage along the track, second means which cooperates with said support structure for mounting the bandsaw on the carriage so that said bandsaw extends cantilevered therefrom and maintaining a portion of the bandsaw blade which cuts the log in a plane substantially parallel to the frame supporting the log.
- 10. A portable bandsaw sawmill apparatus comprising an elongated frame including means for supporting a log in a plane, a single rail extending horizontally along one side of the frame and the log, a carriage including a support structure, a bandsaw having a pair of wheels with a bandsaw blade entrained thereon, the bandsaw blade comprising a continuous band having transversely extending teeth, means which cooperates with said support structure for mounting the bandsaw to the carriage so that said bandsaw extend cantilevered therefrom, means for mounting the carriage only on the single rail for horizontal movement therealong, and means for moving the carriage horizontally along the single rail, the bandsaw extending cantilevered over the frame from the carriage such that a portion of the bandsaw blade which cuts the log moves transversely through the log in a plane parallel to the plane in which the frame supports the log as the carriage moves along the single rail.
- 15. A portable bandsaw sawmill comprising an elongated frame for supporting a log in a plane, track means extending along one side of the frame, a carriage, means for mounting the carriage on the track means for movement therealong, a bandsaw having at least two wheels and a bandsaw blade entrained on the wheels, the bandsaw blade comprising a continuous band having transversely extending teeth, means for moving the carriage along the track, means for mounting the bandsaw on the carriage to maintain a portion of the bandsaw blade which cuts the log in a plane over the frame supporting the log, the mounting means for the bandsaw and carriage being constructed such that the bandsaw is cantilevered outwardly over the log and movably supported in such cantilevered fashion only on said track means.
