ABSTRACT:
A release mechanism for use with an underwater exploration device such as one used to release ballast from an ocean bottom seismograph which includes primary and secondary release actuating devices. Ballast weights are secured to the seismograph by cables which themselves are secured by levers held immobile by a removable pin. The pin can be removed by the primary release actuating device, a rotary solenoid with linkage arms which produces a linear stroke, or by the secondary release actuating device, a coil spring held in compression by means of an electroplatable wire around and under the head of the pin, or both, allowing the levers to pivot releasing the cables and ballast weight. The mechanical advantage of the levers is utilized to allow a relatively heavy ballast weight to be held while requiring a much smaller force to remove the pin allowing its release.
