ABSTRACT:
The present invention relates to an apparatus that is adapted to be attached adjacent to a conventional grinding machine for sharpening circular saw blades, especially the type having laterally off set teeth. The sharpening attachment of the present invention basically comprises a connecting bracket, an elongated blade support member adjustably secured to said bracket and provided with a movable traveler that is adapted to be secured to a saw blade to be sharpened. The traveler is actuated back and forth so as to bring the saw blade into sharpening engagement and disengagement with a sharpening stone forming a part of said grinding machine. In the method utilized in the case of a circular saw blade having laterally off set teeth, when secured within the sharpening attachment, every other tooth would assume a lowermost position and these teeth are first sharpened. Then the blade is turned over and the other teeth are sharpened in a like manner. Particularly, the saw blade through the blade support member is moved back and forth into and out of engagement with the sharpening stone.
