This invention comprises an actuator for a mechanical counting device for recording and storing data. This actuator includes a weight having an eccentric center of mass which is freely pivotable in one plane within preset limits in response to an externally applied impulse force of a predetermined magnitude to apply a torque force within prescribed limits to a shaft which, upon rotation thereof under the influence of such torque force, actuates the counter mechanism to record a count. Means are provided to apply counter torque force of a constant predetermined magnitude to the shaft, so that the counter is actuated only in response to a resultant torque force of a predetermined magnitude generated by the impulse. Torque limiting means are also provided to permit operation of the counter within an impulse band or range greater than the band or range achievable without use of such torque limiting means. Author
