Abstract:
The invention is a portable band sawmill which is able to make bi-directional horizontal cuts, as well as vertical cuts. A special carriage with a U-shaped inner member pivotally connecting two band saw wheel support members makes this possible. The wheel support members of the saw blade carriage are pivotally connected at one end to traveler assemblies which are, in turn, movably connected to vertical members of a generally rectangular, vertical sub-frame. The sub-frame spans the width of, and is, in turn, movably connected at two or more points, at least one on each side, to a generally rectangular horizontal main-frame. The horizontal main-frame supports a log to be cut. The vertical sub-frame is moved back and forth on the main-frame to provide horizontal cuts. The saw blade carriage is moved up and down on the vertical sub-frame by the traveler assemblies to provide horizontal cuts at different heights, and/or vertical cuts. The saw blade carriage, which supports the band saw, can rotate 0. degree. -180. degree.
