An automatic tool transport mechanism for a machine tool having an operating axis, in which a tool is to be transferred between the operating axis of such a machine and the storage structure, with the tool being supplied to the operating station on such operating axis, or to such a storage structure on a storage axis thereof, at least a portion of which is spaced from such operating axis, and employing a transfer arm adapted to be mounted on a machine tool for movement in a predetermined path from a first position adjacent said operating axis to a second position adjacent said space portion of said storage axis, tool gripping means carried by said arm movable in a second predetermined path operative to correspondingly orient such tool gripping means and a tool carried thereby on either said operating axis when said arm is in said first position, or on said storage axis when said arm is in said second position, means being provided for selectively actuating said gripping means to and from tool-gripping and tool-releasing position when said gripping means is operatively disposed on either such an operating axis or such a storage axis, the movements of said transfer arm and gripping means preferably being effected mechanically in fixed predetermined sequence without the use of sensors and the like.
