Laterally engageable and releasable nut assembly for threaded shafts
First Claim
1. A laterally engagable and releasable nut assembly for a threaded shaft comprisinga nut member having a slot extending outwardly from a central portion thereof toward its perimeter, the inner end of said slot being threaded to match the threads of said shaft and the outer slot end terminating short of said perimeter;
- said slot having a width at least equal to the diameter of the shaft to permit the nut member to be laterally inserted into and removed from threaded engagement with the shaft;
a collar member mounted for rotation on said nut member, said collar member being rotatable in a path surrounding said shaft and traversing the outer portion of said slot, andcam means on said collar member responsive to said relative rotation of the members for confining said assembly in threaded engagement with said shaft.

Abstract
A nut assembly for threaded shafts capable of being quickly released from threaded engagement with a shaft, and then moved longitudinally to a selected position on and re-engaged with the shaft. The assembly is characterized by a pair of collar members respectively mounted for relative rotation about fixed parallel axes so as to provide an opening between opposing peripheral segments thereof for receiving the shaft. The inner periphery of one of the members is threaded at the opening and the inner periphery of the other member is provided with a cam surface responsive to said relative rotation for laterally pressing the shaft into threaded engagement with the opposing collar member.
