ABSTRACT:
An undersea release apparatus for positively releasing a connecting link from an underwater device, the apparatus comprising a latching mechanism on the device for latching the connecting link to the device in a latched condition, and for unlatching the connecting link to be free of the device in an unlatched condition. A driving mechanism positively moves the latching mechanism to its unlatched condition. The driving mechanism drives a rotatable cam which retains a pelican hook at a fixed latched position, and positively drives the pelican hook from the latched position to an unlatched position. The apparatus is also provided with an arming function, whereby the rotatable cam is rotated in a direction opposite to that which is effective to unlatch the connecting link, whereby the pelican hook is pivoted back to its first or latched position in which the pelican hook relatches with the connecting link.
