An intermittent motion transmitting and timing system for actuating an uplock latch device or the like to provide for high speed, timed power transmission at maximum load requirements. An inverse geneva drive mechanism is coupled between a rotational input drive and a rotatable output drive. A drive train between the input drive and the inverse geneva drive mechanism includes at least a pair of meshed elliptical gears for maximizing output torque for a given input torque. A drive train between the inverse geneva drive mechanism and the rotatable output includes a regular geneva drive mechanism and a shift mechanism. The inverse geneva drive mechanism, the regular geneva drive mechanism and the shift mechanism are coupled in timed relationship by an odometer device whereby the rotatable output is moved at its maximum load when the inverse geneva drive mechanism delivers maximum torque, and whereby the shift mechanism is actuated by the regular geneva drive mechanism when the inverse geneva drive mechanism is at a dwell condition.
