An electrical pulse generator responsive to chuck drive motor shaft rotation feeds pulses to a revolution indicator which also receives an alternating current input signal whose frequency corresponds to the line frequency of the electrical source which feeds the chuck drive motor. A decrease in shaft rotation speed and a variance between the frequency of the pulses from the pulse generator and the frequency of the alternating current source to the motor results in de-energization of a control co...

A power transmission apparatus is disclosed in which a power output shaft is connected to both a manual input means and a power input means. Means are provided to automatically disengage the power input upon actuation of the manual input. Alternative embodiments disclose means to prevent rotation of the manual input handle during engagement of the power input means.
