Abstract:

An attachment for a rotary rasping surface scarifying tool has a base member affixable on a rotary scraping tool and provided with a recess receiving a rotary blade of the tool in such a manner that the teeth of the blade are partially covered and partially exposed when the base member is resting on a surface of the base member which is substantially parallel to the rotary plane of the blade. A sloped surface of the base member causes a portion of the teeth of the blade to be exposed and permits the tool to be tilted so as to bring the rotating blade into engagement with a surface to be worked, while a guard is pivotally mounted on the base member in such a manner as to cover the exposed portion of the blade whenever the base member is resting on the level, inoperative position of the attachment.
