ABSTRACT:
An apparatus for mounting a hollow cylindrical member, such as a magnetic tape reel hub, has an arbor and a chuck longitudinally slidable on such arbor. The chuck includes an expansible device for releasably retaining the hollow cylindrical member and a pair of tensioning members having meshing threads and being coupled to the expansible device for releasably retaining the hollow cylindrical member. A driving member assembly having a pair of driving members with meshing threads for varying the position of the chuck along the arbor is coupled to the arbor and chuck for adjusting the position of the chuck to an axial dimension of the hollow cylindrical member. The tensioning members of the chuck may be arrestable relative to each other to inhibit unintended loosening of the chuck from a retained hollow cylindrical member.
