Abstract:
1. A nut assembly for cooperative operation with an externally threaded shaft having a first diameter and a first, central axis, said nut assembly comprising: a. a first bushing having a first, through bore of second diameter, so as to be larger than said first diameter and having a second, central axis, and at least two slots formed therethrough; b. a second bushing located at least partially inside said first bushing and having a second, through bore of third diameter, so as to be larger than said first diameter and having a third, central axis, said first and second bores configured to have the shaft extend therethrough with said first, second and third axes coaxial; c. at least two, physically separate sections each having a first surface portion formed with thread portions configured to be mateable with the thread of said shaft; d. means for pivotally attaching said sections to said first bushing, wherein each of said sections is positioned within a respective one of said slots and is moveable about said pivotally attaching means between first and second positions within the respective one of said slots, and wherein said surface portion of each of said sections is configured to be spaced radially outwardly from said shaft, and in threaded engagement with said shaft, respectively; and e. each of said sections having a second surface portion cooperable with a third surface portion of said second bushing for movement of said sections between said first and second positions thereof in response to relative axial movement of said first and second bushings.
