Abstract
Abstract A saw apparatus having an arbor assembly and coacting actuating means, the assembly comprising a plurality of saws secured to the adjacent ends of telescopic shafts of progressively inward increasing length supported by and having slidable connection with a longer rotatable axle by common driving means. Preferably, the slidable connection includes coacting keys and keyways extending longitudinally of the drive means, shafts and axle with adjacent keyways being relatively staggered and spaced progressively outward toward the saws. The actuating means may include pressure fluid cylinders, having piston rods projecting toward the saws and attached to the opposite adjacent ends of the saw shafts with the cylinders and rods of the longer shafts being movable with the reciprocation of the rods and cylinders of the intermediate shafts and the piston rod of the shortest shaft, and thrust members for movably supporting said cylinders of said longer saw shafts and all of said piston rods as well as permitting relative reciprocation of the latter cylinders.
