Abstract
Locking apparatus encloses and frees an end portion of a shaft for rotation at a first position of the apparatus relative to the shaft. The locking apparatus further encloses, engages, and prevents rotation of the shaft end portion at a second position of the apparatus relative to the shaft. Respective ends of the apparatus are oriented toward the shaft at the first and second positions. The first position of the locking apparatus permits rotation of the shaft and the second position prevents shaft rotation and related movement of associated implements.
