Abstract
A method and apparatus is disclosed for permitting the passage of conduits through the hull of a boat without the creation of additional holes. A conduit-accommodating passageway is defined through the boat's scupper which bypasses the check valve that is associated with the scupper to prevent backflow. An annular body having a radially-extending conduit-accommodating passage communicating between its O.D. and its I.D. is positioned with respect to the scupper so that the fluid passing through the scupper and check valve passes through the generally annular body's I.D. while conduit passing through the radially-extending passage passes through the scupper but bypasses the check valve.
Claims16
For use with a boat having
- a deck,
- a hull generally circumscribing the deck;
- at least one scupper having an inlet positioned to accept the ingress of liquid from the deck, an outlet for discharging said liquid to the exterior of the boat, a conduit for carrying the liquid from the inlet to the outlet, and a check valve for permitting the carried liquid to flow in substantially one direction only,
- a conduit-passage ring for permitting mechanical and electrical connections to be made between the interior and exterior of the hull without breaching the hull and comprising:
- a generally annular body having a radially-extending, cable-accommodating passage communicating between its OD and its ID, said generally annular body being positioned with respect to the scupper so that the fluid passing through the scupper conduit passes through the generally annular body's ID while cable passing through the radially-extending passage bypasses the check valve.
A conduit bypass ring comprising a generally annular body formed about a central axis between interior and exterior surfaces, and adapted to be mounted between the fitting of a scupper and the body of a check valve so that the passageway circumscribed by its interior surface passes fluid from the scupper to the check valve, said annular body including a radially-extending, cable-accommodating passage communicating between its exterior and interior surfaces.
In combination:
- a scupper having a scupper conduit extending from an inlet end adapted for fluidic communication with the deck of a ship to an outlet end adapted for fluidic communication with the region exterior to the hull of a ship, said scupper further including a flanged and generally annular fitting adapted to be sealingly mounted on the exterior of the hull in generally co-axial alignment with the scupper conduit at the scupper outlet to secure the scupper conduit to the hull at the outlet;
- a check valve adapted to be mounted adjacent an end of the scupper conduit, said check valve including a flanged check valve body defining a fluid-conducting passageway, and means for permitting the substantial flow of fluid through said passageway towards the scupper outlet only, the check valve being adapted for mounting with its passageway co-axially aligned with the scupper conduit;
- an annular conduit-passage ring positioned between the scupper flange and the check valve flange in general co-axial alignment therewith, the ring including a radially extending passage that communicates between the exterior and interior of the ring to permit the passage of a conduit from the hull's exterior to enter the scupper conduit while bypassing the check valve.
For use with a boat having a scupper and a check valve associated with the scupper to prevent backflow through the scupper, apparatus for permitting the passage of one or more conduits through the hull of a boat without the creation of additional holes comprising:
- a body positioned with respect to the scupper and cooperative therewith to define a conduit-accommodating passageway through the scupper which bypasses the check valve.
