Abstract
A horizontal power band saw having a frame fabricated of rigid weldments (as opposed to castings) thereby to appreciably lower the cost of the band saw. A system is disclosed for accurately pivotally mounting the saw head on the saw bed, for adjusting the pivotal axis of the head parallel to the bed, and for positively holding the head in desired relation with the bed so as to enable the head to be repeatedly and accurately raised and lowered while the blade of the saw is held in a plane generally perpendicular to the bed. The saw blade is tensioned in such a manner that a desired tension load can be accurately applied to the blade and so that the tension load on the blade can be accurately read out. Also disclosed is the provision of guides for holding the blade in a desired cutting orientation with the guides including guide rollers, thrust bearings, and carbide blade guide inserts wherein the rollers, bearings, and inserts may be readily and accurately adjusted so as to accurately guide and hold saw blades of varying thicknesses. Further the band saw includes a quick-acting vise enabling the saw operator to quickly release a work piece and to positively grip the work piece in an…
