ABSTRACT:
A reel hub latch for use in holding rotating devices, such as a reel of tape, rigidly and concentrically to a rotating shaft, in which a seating surface is provided for the reel on the outside surface of a first or hub portion of the device. There is an annular channel in the outer surface of the hub in which is provided a ring of deformable material, which has two parallel faces perpendicular to the axis of the ring. These two surfaces are provided with shallow narrow ridges molded into the material which are equally spaced around the circumference of the ring. The walls of the annular channel are likewise provided with an equal plurality of shallow narrow grooves in the parallel facing walls of the channel. A segmented disk is provided in the hub to extrude the deformable material outwardly with the movement of the handle, and to withdraw the ring material into the channel when the handle is moved in the reverse direction. The purpose of the ridges and grooves is to insure that the ring of deformable material does not rotate around the axis of the hub when there is a high torque between the rotating hub and the tape reel.
