The claim is for a wheel secured to a vertically journalled shaft, and a series of radial buckets inclined from the vertical at substantially an angle of forty-five degrees, and secured lo the rim, in combina- tion with a frame surrounding the buckets, a cover therefor provided with a series of openings, each extend- ing over two or more buckets, and a curved conductor BOLTON COMBINATION MOVEABLE SAW STRETCHER AND SHEAR. The fine tensioning of band saws being so essential to the best results in their operation, it stands to reason that a good machine for this purpose is indispensable. The Bolton 12-inch combination movable saw stretcher and shear, No. 5, herewith illustrated, is manufactured by Messrs
