Description:

"My invention relates to a peculiar manner of dressing, setting, and swaging the teeth of a band-saw for dividing staves or other curved pieces of wood from a block or bolt lengthwise of the grain, the teeth being constructed somewhat like the bit and face of a plow-plane, grooving their way through the wood in a similar manner." The teeth are set towards the inside of the intended curve, and are swaged so that the cutting edge is slightly forward of the plane of the blade. Other than the swaged tooth-edge, the front face of the blade is parallel to the rear edge of the blade. This construction limits the rate at which the blade can feed.
