| Abstract
This invention relates to a greatly simplified tool storage and changing mechanism for a machine tool. To accomplish this, a plurality of cutting tools are disposed in a radial array relative to a tool receiving operator. Each tool is carried at the outer end of a single pivotal support with each respective support being individually pivotal to insert a tool carried thereby into the tool operator. After insertion by a single movement of its associated support, securing means are actuated to releasably secure the inserted tool to the operator for performing a desired machining operation. The inserted tool can be returned to a parked or storage position by simply releasing the securing means and pivoting the associated tool support outwardly for returning the tool carried thereby to stored position. In other words, each tool support is pivotal in one direction for inserting a tool into the operator, and is pivotal in open direction for inserting a tool into the operator, and is pivotal in the opposite direction for returning that tool to a radially disposed storage position.
