ABSTRACT:
A hollow-cylindrical member, such as a reel, is releasably retained on a rotatable hub against forces tending to loosen the reel. To this end, a plurality of locking keys are inserted into corresponding axial slots in the reel at the inside thereof. These locking keys are first driven up corresponding ramps on the hub into engagement with the inside of the reel at corresponding slots. After such engagement, and during rotation of the hub and reel, the locking keys are continously biased or further urged into their corresponding slots in order to inhibit any looseness between the releasably retained reel and the rotating hub. By way of example, tape reels of large size and mass may thus be securely retained against strong inertial forces occasioned particularly during rapid reversals of the reel rotation as occurring, for instance, in modern instrumentation tape recording and data processing machines.
