Abstract: A portable sawmill is provided in which a rigid straight channel support is placed on a floor or on the ground with one end slightly elevated. A pair of longitudinally spaced log supports are mounted in the channel piece at a distance corresponding to the length of a log to be placed thereon. A carriage with rollers is mounted to ride along the upturned edges of the channel piece and is adapted to roll by gravity from the elevated end of the channel piece to the lower end. The carriage includes a bandsaw driven by a low horse power motor and is equipped with a release mechanism for automatically disengaging the drive between the motor and the saw at the end of a cutting stroke. A jacking mechanism and adjustable shelves on the log supports are included for raising the log to a new height after each cut.

Abstract: A portable sawmill includes a log supporting mechanism for holding a substantially horizontal log. A chain saw with a substantially horizontal effective cutting edge at least as long as the log is supported at only one end by a saw mounting assembly with the cutting edge generally parallel to the axis of the log. The saw mounting assembly is adapted for lateral movement relative to the log, as well as upward and downward movement, so that the saw can be positioned beneath a portion of the log and moved upwardly through the log to cut wood slabs. The saw is pivoted to the saw mounting assembly so that the angle between the effective cutting edge and the axis of the log can be adjusted to produce elongated wood fibers during cutting. A pivoting mechanism is provided for rotating the log between cuts so that slabs tapered from one side to the other can be cut.

Abstract: Apparatus for accurately cutting logs and large timbers at selected angles with a chain saw is disclosed. The invention includes a base framework which works in combination with a support table. The base framework includes vertical rods mounted to the base framework. The bar of the chain saw is secured to guides which slide up and down on the rods. The chain saw and base framework combination are pivotally secured to the support table such that the chain saw blade can be positioned at various angles with respect to the log or other material being cut. Once the angle has been selected, the chain saw and base framework combination are secured to the support table such that the angle at which the logs are cut will remain constant as the saw is operated. One embodiment includes means for counter balancing the chain saw weight to aid in operation of the saw.
