ABSTRACT:
A reel assembly apparatus for coaxial magnetic tape reels is provided in which both an inboard reel and an outboard reel may be reliably clamped to their respective drive spindles from the outboard side of the assembly apparatus with ease and convenience. For the purpose of clamping the inboard reel, an internal locking nut extends radially in the plane of the inboard reel from its drive spindle into threading engagement with a hub of the inboard reel. A linkage, extending axially through the outboard drive spindle, rotates in response to turning movement of a bail accessible to an operator. The locking nut, in response to the rotation of the linkage, (1) initially causes the inboard hub to rotate, relative to the inboard reel, a limited amount into a reel-clamping position, and (2) then causes an axial movement of the inboard hub. This latter movement drives the inboard reel axially, to clamp it against a radially extending member of the inboard drive spindle. A second locking nut, coupling a second bail to the outboard hub, serves similarly for clamping the outboard reel to its drive spindle. With the locking nuts in the planes of their respective reels, the reels can be positioned axially immediately adjacent each other, thereby conserving space for a compact design.
