Abstract
Shear pins indirectly interconnecting breaker rings and shaft components of the rotor assembly of the apparatus are so located and mounted as to be readily replaceable when sheared by relative rotative movement between the components. Relative rotative movement of the components is detected and changes the operating condition of the drive motor and/or a signaling device associated with the apparatus.
