ABSTRACT:
Digital control signals can be accepted and translated directly into low inertia, high torque intermittent rotary motion by this fast time response apparatus which comprises a low mass, rotatably mounted driving member, a source of driving torque such as a torque motor, a low rotary inertia torsion member which interconnects the driving member with the torque member to thereby apply torque to rotate the driving member, reciprocatably operated escapement means for controlling the rotation of the driving member, and a two-ended toggle linkage connected at one end in an operating relationship with the escapement means, and at the other end to a mechanism which supplies a reciprocating driving force. The toggle linkage has a normally flexible knee joint which can be selectively locked by electromechanical means to which the digital signals are supplied. When locked, the toggle linkage transmits a reciprocating driving force from one end, thereby triggering the escapement means so that the driving member is selectively, incrementally rotated under power from the torque motor through the torsion member.
