Abstract
A magazine (10) for a machine tool (not shown) comprises a number of links (12) joined together by pins (14) to form a closed chain (16). A socket (32) is formed in each link for receiving a tool (34) to position the tool center line (36) midway between and in parallel relation with, the axes (40) of the two pins (14) which join the link to adjacent links in the chain (16). A frame (18) supports the chain (16) and received tools (34) for movement along a path of travel to selectively position the tools, the path including sections (26) of little or no curvature, and sections (28, 30) of substantial curvature. To maintain tool movement precisely along the path of travel, and thus prevent contact between tools in adjacent links (12) when the adjacent links travel around a section (28, 30) of substantial curvature, guide bearings (54) are joined to the links and constrained to move along a channel (56) which is in parallel relation with the desired chain path of travel.
