on the size configurations of the assembly components stub shaft 22 is provided on the opposite side of adapter 14 from the side providing closed bore 20 the coupling of stub shaft 22 with backstopping clutch 16 allows for the transfer of a braking force from clutch 16 to adapter 14 and shaft 12 to prevent rotation of shaft 12 in one direction as seen in fig2 backstopping clutch 16 includes an inner race 24 and an outer race 26 inner race 24 of clutch 16 rotates with driven shaft 12 through the coupling of inner race 24 to stub shaft 22 of adapter 14 the relative speed of rotation of inner race 24 may vary based on the relative size ratio of the diameter of stub shaft 22 to the diameter of driven shaft 12 inner race 24 is permitted to rotate in one given direction through its engagement with stub shaft 22 therefore the engaging rotation of driven shaft 12 with adapter 14 results in the simultaneous transferred rotation of inner race 24 referring to fig3 clutch 16 further provides a plurality of spring loaded plungers 36 disposed about the circumferential periphery of inner race 24 each of the spring loaded plungers 36 are engagingly coupled to a locking roller 38 the individual spring loading of locking rollers 38 provide constant force between locking rollers 38 and both the inner race and outer race 24 and 26 respectively locking rollers 38 engage a cylindrical groove 40 provided by outer race 26 the cylindrical groove 40 provided by outer race 26 reflects the circular exterior of roller 38 for receiving and providing a surface of engagement for each of the locking rollers.
