Device for setting circle saws

Abstract

A setting apparatus for circular saws is described in which an elongated channel iron base is employed to carry both the setting device and the cooperating means. The channel iron base is of sufficient length to accomodate an open-end slidable box, said box supporting a fixed saw holding arbor; said slidable box being movable on said elongated channel iron base, and also longitudinally adjustable to position the peripheral edge of a circle saw of any size in proper relation to the edge of the anvil. The anvil is located at the right end of channel iron base and said slidable box being releasably lockable to the channel iron base at any point desired. The right end of the elongated channel iron base is provided with two angle iron plates, welded or bolted in place, and positioned with sufficient width to accept a stress-proof metal bar arm equipped with a one-fourth inch tool bit as the striking element. The metal bar arm and the metal angle plates are bored to receive a bolt pivotally supporting said bar arm. The extreme right end of elongated channel iron base has an elongated slot in which an eccentric throw is supported. The eccentric throw is drilled and threaded through it's center to receive a short threaded shaft on which it rocks, said shaft being equipped with a hex nut to receive the end of lever which actuates the eccentric throw, forcing the metal bar arm carrying the striking element to pressure each tooth as presented with sufficient force to uniformly and precisely set each tooth, and falling away of it's own weight when the operator releases the lever. The channel iron base carrying the setting apparatus and slidable box is releasably lockable to any work bench and is portable.
