Claim 1
Independent Claim
188 words
An adapter for converting flush mount installation of marine instruments and the like to surface mount installation, said adapter comprising: an adapter member (30) consisting of a sealing washer fabricated of a resilient material and of generally dish-shaped construction including a central frustoconical opening (32); a first annular, generally smooth end surface (38) inclined inwardly from an outer edge to an inner edge contiguous with said opening (32) for forming a generally smooth concave profile; a second annular, generally smooth end surface (34) disposed opposite from said first end surface (38) and being substantially flat from an outer edge to an inner edge; an annular generally smooth inclined connecting surface (36) having an inner edge joined with the outer edge of said second annular end surface (34), and an outer edge joined with the outer edge of said first annular end surface (38); said first annular end surface (38) and said annular connecting surface (36) converging outwardly of said adapter member (30) for forming a gradually tapered portion which decreases at a generally constant rate and has its apex at the outermost periphery of said adapter member (30).

An adapter for converting flush mount installation of marine instruments and the like to surface mount installation, said adapter comprising: an adapter member (30) consisting of a sealing washer fabricated of a resilient material and of generally dish-shaped construction including a central frustoconical opening (32); a first annular, generally smooth end surface (38) inclined inwardly from an outer edge to an inner edge contiguous with said opening (32) for forming a generally smooth concave profile; a second annular, generally smooth end surface (34) disposed opposite from said first end surface (38) and being substantially flat from an outer edge to an inner edge; an annular generally smooth inclined connecting surface (36) having an inner edge joined with the outer edge of said second annular end surface (34), and an outer edge joined with the outer edge of said first annular end surface (38); said first annular end surface (38) and said annular connecting surface (36) converging outwardly of said adapter member (30) for forming a gradually tapered portion which decreases at a generally constant rate and has its apex at the outermost periphery of said adapter member (30).
Claim 3
Dependent Claim
128 words
The adapter member as defined in claim 1 in combination with a mount housing (10) for attaching a sensing assembly (16) to an underwater portion of a hull (22') of a marine vessel; said mount housing (10) including a beveled end (14) for complementary mating engagement with said frusto-conical opening (32) and in planar alignment with said second annular, generally smooth and flat end surface (34); said mount housing (10) being generally cylindrical for being received in a cylindrical opening (24') which extends completely through said hull (22'); and means (26) for securing said mount housing (10) and said adapter member (30) to said hull (22') with said first smooth end surface (38) being flexed from its generally smooth concave profile into flush engagement with said hull (22').
