(under the class definition) Device including a tool and tool-support assemblage which includes an element adapted to give sustaining effort to the tool and further adapted to yield without exceeding the elastic limit thereof and thereby allow the cutting edge of the tool to move relative to other portions of the assemblage; or including a tool, a portion of which is adapted to yield without exceeding the elastic limit thereof and thereby to allow the cutting edge of the tool to move relative to another portion of the tool.
(1) Note. By the definition of a tool-support*, any motion of the cutting edge relative thereto must be at a time when the tool is not in operation.
SEE OR SEARCH THIS CLASS, SUBCLASS:
124+, for a resilient means connected at one end thereof to a tool or a tool-support, which resilient means is adapted to store energy therein and to release that energy to drive the tool.
143, for yieldable means which may be resilient and is particularly adapted to absorb vibration transmitted from the tool.
154+, for a tool, including means to move that tool radially and including resilient means adapted to act in opposition to the moving means.
