Patent ID: 6959530

Claim:
Apparatus comprising: a cutting knife with an aperture therein; a rotary member, the rotary member being disposed for rotation about a first axis, an opening is disposed in the rotary member; a knife adapter disposed in said opening, said knife adapter having an aperture therein; a pin disposed about a second axis, one end of the pin being operatively configured so that it will not pass through the aperture in the knife and the other end of the pin having a recess therein; said pin extending through the aperture in the knife and the aperture in the knife adapter, a retainer also being disposed over the other end of the pin to a first position thereof; and when the retainer is moved in a direction transverse to the axis of the pin to a second position of the retainer a first part of the retainer engages the recess in the pin and a second part of the retainer engages a ramped projection to hold the retainer from moving from the recess in the pin wherein the ramped projection is operatively attached to the knife adapter, whereby movement of the second part of the retainer over the ramped projection causes the second part of the retainer to move at least partially in the first parallel direction to the second axis when moved toward the second position thereof and then back in an opposite direction to the first parallel direction once the second part of the retainer is disposed completely over the projection.
