difficult to unclamp the'outer wheel without also
disturbing the clamping means for the inner
wheel. This is for the reason that the threads
of the outer clamping member are of greater
radius than those for the inner clamping mem
ber and, consequently, the eifective frictional
resistance to the turning of the outer member on~
the inner member is greater than the resistance

It is the object of the invention to provide
means for preventing the loosening of the clamp 35 by the member G. This member does not inter
