Abstract

A through-hull fitting having a spherical socket into which an electrical transducer mounted within a ball can be adjusted to position the transducer in a vertically aligned axis.

Claims

1. A nautical transducer mounting device for through-hull mounting in the side walls of a hull of a vessel below water line comprising a cylinder having an outwardly extending flange at one end in which the flange is adapted to rest against outer wall of the hull and the cylinder is arranged to penetrate through the hull into the interior of the vessel, mounting means on the outer face of said cylinder locking said flange tightly against the wall of the hull of said vessel, said cylinder having an interior cavity terminating with a partial spherical edge, a ball having a diameter smaller than the side wall of the interior of said cylinder and substantially the same diameter as said spherical edge, a plug threadedly mounted on the interior wall of said cylinder having a spherical lower surface having substantially the same diameter as said ball engaging the upper surface of said ball, said ball containing an electrical apparatus, said plug being movable in a first position to allow said ball to be rotated to register the electrical apparatus in a predetermined registration and being movable to a second position in compression against said ball to lock said ball in said fixed predetermined registration.

2. An apparatus according to claim 1 and wherein the external surface of said flange is formed with a raised protuberance having an underface which is coextensive with said partial spherical edge.

3. A nautical transducer mounting device for through-hull mounting in the side walls of a hull of a vessel below water line comprising fitting means mounted through the side wall of said hull, a bore mounted in said fitting means, a spherical socket mounted within said bore, a ball mounted within sAid spherical socket and lock means operative with said spherical socket movable from a first position to allow said ball to rotate freely and to a second position to lock said ball in fixed alignment and an electrical transducer mounted rigidly within said ball, said transducer being of the type requiring a fixed registration relative to the body of water whereby said ball can be rotated when said lock means is in said first position to orientate said transducer to its predetermined alignment with respect to the water and thereafter said lock means is movable to the second position to lock said ball in said fixed alignment whereby said transducer is maintained in its predetermined water alignment.
