Abstract
A radially displaceable coupling between a printing disc and the drive shaft of a printing machine. A bracket having a planar surface is secured to the drive shaft, the bracket having a planar face. Clamps are provided on one of the disc and bracket faces for engagement with the other of said disc and face. A resilient arm, including a zig-zag configured portion terminating in a blade having an inclined lateral surface, is formed on one of the disc and bracket and a recess is provided in the other of the disc and bracket for receiving the resilient arm to effect securement therein in a wedgelike engagement. A lateral surface borders the recess and coacts with the lateral blade surface. The lateral surfaces are convergent relatively coacting when the arm is engaged within the recess to prevent angular movement of the disc and to cause the disc to bear against the drive shaft at a location diametrically opposite to the location of the recess.
