Abstract
A stern light or distress signaling transmitter is continuously electrically activated at any height above the hull of a boat and when not in use may be retracted and stored in a chamber below the deck in the hull. A motor driven drive cord is wound around a takeup reel and includes a pair of electrical connectors embedded therein which are in electrical contact with a power source through a pair of ring conductors mounted on a plate rotatable with the takeup reel. When the light is retracted it is flush with the top surface of the deck.
Claims11
A retractable signaling means in combination comprising, a body having an outer wall and an interior chamber, a signaling unit mounted in said interior chamber and having
- telescopic sections movable upwardly through said outer
- wall between raised and lowered positions, a signaling
- means mounted on the upper end of the uppermost telescopic
- section,
- a drive cord positioned in and extending along the axial center of said telescopic sections extending from the uppermost section to said interior chamber where it is coiled on a takeup reel, said cord including at least one electrical conductor connected at one end to said signaling transmitter and at the other end to a terminal ring mounted on said reel to rotate therewith, said drive cord having sufficient stiffness and strength to act in compression and tension to push said telescopic sections upwardly to said raised position and pull said telescopic sections down to said lowered position upon operation of said takeup reel,
- an electrical source including at least one stationary electrical conductor in electrical contact with said terminal ring whereby said signaling means and electrical source are adapted to be continuously electrically interconnected between and during retracted and raised positions of said telescopic sections, and
- said electrical source electrical conductor being in electrical contact with said terminal ring through a brush in electrical contact with said terminal ring.

A retractable signaling means in combination comprising, a body having an outer wall and an interior chamber,
- a signaling unit mounted in said interior chamber and having at least one tube section movable upwardly through said outer wall between raised and lowered positions, a signaling means mounted on the upper end of the tube,
- a drive cord positioned in and extending along the axial center of said tube extending from the upper most section of the tube to said interior chamber where it is coiled on a takeup reel, said cord including at least one electrical conductor connected at one end to said signaling means and at the other end to a terminal ring mounted on said reel to rotate therewith, said drive cord having sufficient stiffness and strength to act in compression and tension to push said at least one tube section upwardly to said raised position and pull said at least one tube section down to said lowered position upon operation of said takeup reel,
- an electrical source including a stationary electrical conductor in electrical contact with said terminal ring whereby said signaling transmitter and electrical source are adapted to be continuously electrically interconnected between and during retracted and raised positions of said at least one tube section and
- said electrical source electrical conductor being in electrical contact with said terminal ring through a brush means in electrical contact with terminal ring.
