(under subclass 72) Device including a tool, tool-supporting structure, provision to secure the tool in a position to perform a cutting operation of the class type, and means to cause the securing provision to become ineffective so that the tool can move relative to the tool-supporting structure and relative to the work into an inoperative position; wherein the means to cause the securing provision to become ineffective includes a surface adapted to contact the work and thereby cause the means to function.

(1) Note. The securing provision of this subclass includes a moving means as well as a means to permit movement of the tool.
