ABSTRACT:
A shaft attachment assembly for fastening a member to a shaft. The shaft has a receptacle end which includes an axial opening therein. A stud is provided for engagement with the receptacle end and has a body portion and a head portion. One of the stud and the receptacle end has surfaces forming a tapered cam surface terminating in a locking detent and the other of the stud and receptacle end has a transverse pin extending laterally therefrom. The member to be fastened to the shaft has an axial passageway therethrough positioned so that when the member is aligned with the receptacle end of the shaft, the passageway and the member will be aligned with the opening of the shaft. The body portion of the stud is extendable through the passageway and the member and the opening in the shaft to bring the pin into rotatable engagement with the cam surface. A resilient tension element is on the assembly to permit relative axial movement as the stud is rotated and the pin follows the cam surface to the locking detent thereby rigidly fastening the member to the stud. The resilient tension element also permits relative axial movement as the stud is rotated and the pin follows the cam slot from the locking detent to the disengaged position where the stud can be removed and the member and the shaft disengaged.
