Abstract
Abstract A cable fitting for ship bulkheads which can be installed after the cable is already in place and testing of the cable connections completed. All parts of the fitting are split diametrically and fitted around the cable from the outside. A housing has a base which is secured to the bulkhead. The cable extends through adjacent circular and frustoconical openings in the housings. A frustoconical compression gland is mounted in the frustoconical opening in the housing. A nut is tightened on the housing to compress the gland inwardly into engagement with the cable. A loosely mounted washer in the nut prevents twisting of the gland. Sealing means are provided in all portions of the fitting.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
246 words
A cable fitting for the bulkhead of a ship or the like comprising a housing, said housing being divided into two sections, fastening means for securing said sections together, said housing having a base, fastening means for removably attaching said base to the bulkhead, said housing having an externally screw-threaded projection, said housing having a cable receiving opening extending therethrough, said cable receiving opening including a frustoconical opening disposed substantially within said projection, a resilient compression gland mounted within said frustoconical opening, said compression gland being divided into two sections, the outer diameter of said compression gland being formed complementarily to said frustoconical opening, the inner diameter of said compression gland having a cable receiving opening, a nut adapted to be screw threadedly mounted on said projection, said nut being divided into two sections, fastening means for removably securing said sections together, said nut having a portion thereof overlying one end of said compression gland, said nut adapted to be tightened on said projection to compress said compression gland longitudinally within said frustoconical opening to reduce the inner diameter of said compression gland into engagement with the periphery of a cable extending through said cable receiving opening, all of the parts of said fitting being split substantially diametrically into two substantially equal and complementary sections, said base having a substantially flat portion adapted to abut against the bulkhead, and split sealing means having overlapped ends disposed between said flat portion of said base and the bulkhead.
Claim 2
Dependent Claim
246 words
A cable fitting for the bulkhead of a ship or the like comprising a housing, said housing being divided into two sections, fastening means for securing said sections together, said housing having a base, fastening means for removably attaching said base to the bulkhead, said housing having an externally screw-threaded projection, said housing having a cable receiving opening extending therethrough, said cable receiving opening including a frustoconical opening disposed substantially within said projection, a resilient compression gland mounted within said frustoconical opening, said compression gland being divided into two sections, the outer diameter of said compression gland being formed complementarily to said frustoconical opening, the inner diameter of said compression gland having a cable receiving opening, a nut adapted to be screw threadedly mounted on said projection, said nut being divided into two sections, fastening means for removably securing said sections together, said nut having a portion thereof overlying one end of said compression gland, said nut adapted to be tightened on said projection to compress said compression gland longitudinally within said frustoconical opening to reduce the inner diameter of said compression gland into engagement with the periphery of a cable extending through said cable receiving opening, all of the parts of said fitting being split substantially diametrically into two substantially equal and complementary sections, said base having a substantially flat portion adapted to abut against the bulkhead, and split sealing means having overlapped ends disposed between said flat portion of said base and the bulkhead.
Claim 3
Dependent Claim
92 words
The structure described in claim 1, said sealing means between said base and bulkhead comprising an annular recess extending around the entire periphery of said flat portion of said base, and a diametrically split seal mounted in said recess, said split seal comprising two complementarily formed semicircular sections, the opposite ends of each of said split seals having substantially half the thickness of the remainder thereof, said ends overlapping each other, each of said ends having a projection and a recess adapted to engage the projection of the other of said sections.
Claim 4
Dependent Claim
71 words
The structure described in claim 1, and a pair of substantially L-shaped recesses formed in the abutting faces of said housing sections, and a pair of complementarily formed resilient seal strips mounted in said recesses, one end of each of said seal strips making sealing engagement with the periphery of said compression gland and the other end thereof making sealing engagement with the sealing means disposed between said base and bulkhead.
Claim 5
Dependent Claim
71 words
The structure described in claim 3, and a compression ring disposed between said nut and said compression gland, said nut having an annular recess in which said compression ring is mounted, said ring being heLd within said recess when the sections of said nut are secured together, said ring having a thickness slightly less than the depth of said recess, whereby said nut is free to rotate without rotating said ring.
Claim 6
Dependent Claim
36 words
The structure described in claim 1, the sections of said compression gland having transversely directed abutting faces, and means integrally formed on said faces for interengagement and alignment of said sections with respect to each other.
Claim 7
Dependent Claim
34 words
The structure described in claim 5, said interengaging means comprising an outwardly projecting pin and a spaced inwardly directed recess formed on each of said abutting faces, said pins removably fitting into said recesses.
