Tool storage magazine for a machine tool

摘要

A tool storage magazine of the type wherein a circulatable endless chain pivotably carries a plurality of tool storage sockets is provided with a cradle member adapted to carry thereon any of the tool sockets indexed to an exchange position and a mechanism for pivoting the cradle member between horizontal and vertical positions. The magazine is further provided with a locking mechanism which prevents a holding plunger of any tool socket indexed to the exchange position from being disengaged from a tool received in the tool socket until the cradle member is pivoted to the vicinity of the vertical position so that the dropping of a tool from an associated tool socket is reliably prevented during pivotal movement of the cradle member.
