摘要：A battery powered signaling device for the rescue of overboard swimmers isarranged in an elongated container in which reciprocal sliding batteries are used asballast for the erection of the signaling elements above the water line; and further, upondeployed erection gravity supplemented by minor force of a conducting compressiblespring that is always in contact with the uppermost positive battery terminalautomatically forces the batteries downward to close an electric circuit by makingcontact between the negative casing of the bottommost battery and conductors leadingto activate the signaling subsystem which is a lighting source in a preferred embodiment.When aboard ship, stowage of the signaling device in an inverted orientation permitsgravity forces to slide the batteries downward to compress the conducting spring andopen the electrical circuit by breaking contact between the battery negative case and thereturn conductors thereby automatically extinguishing the signal in a wide range of rolland pitch motions of the ship. An end cap, sealed against entry of water, is removable toallow withdrawal of the battery magazine for servicing as required.
