  • Automatic marker buoy release mechanism
    Patent number: 4721486
    Abstract: A marker buoy releasing mechanism for marking the location of a sunken boat includes an air tight housing having a differential pressure switch mounted therein for sensing the pressure within the housing and externally thereof. When the differential pressure sensed by the switch increases to a predetermined value, indicative of sinking of the boat, the switch will close to complete the electric circuit between a battery and an electrically operated device. When electric power is coupled through the differential pressure switch to the electrically operated device, it will be operated to actuate an inflating mechanism which supplies compressed gas to an inflatable marker buoy which floats to the surface of the water on the end of a tethering line.
