  • Automatic release mechanism for a tether
    Patent number: 4126850
    Abstract: Warning lights are releasably secured, by means of clamps, along the length of a cable employed as a tether for a balloon. The cable passes through a relatively stationary, conically shaped cam at the base of the cable. As the balloon is winched back to earth, a cam follower on each clamp is forced into engagement with the cam, causing the jaws of the clamp to open and the clamp and its indicator automatically to be released from the cable.
