In this deisign a keyway is cut into the blade extending from the center bore. The disperser blade is sandwiched between a pair of taper plates, which are also keyed.

COMBINATION KEYWAY and PIN HOLES: Unique to Hockmeyer, this design is typically used with machines over 60 HP and dispersion blades over 18" diameter, the bore and keyway is supplemented by the addition of 2 or more pin holes.
