Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
A cable joint box for enclosing the connection of the ends of a pair of cables, said cable joint box comprising: a. a tubular enclosure open at each end; b. a pair of end members adapted to close the respective ends of said tubular enclosure, said end members including an opening to permit a cable to pass therethrough; c. means to interconnect said end members to position the same at a predetermined spacing; d. tightening means carried by said end members and engageable therewith for axial movement relative thereto, said tightening means engageable with said tubular enclosure; e. annular sealing means positioned between said tightening means and an end of said tubular member, whereby said sealing means is compressed to provide a fluid-tight seal between said tubular member, said tightening means, and said end member when said tightening means is moved axially toward the end of said tubular enclosure; and f. each of said end members including means to secure the respective cables thereto.
Claim 2
Dependent Claim
164 words
A cable joint box for enclosing the connection of the ends of a pair of cables, said cable joint box comprising: a. a tubular enclosure open at each end; b. a pair of end members adapted to close the respective ends of said tubular enclosure, said end members including an opening to permit a cable to pass therethrough; c. means to interconnect said end members to position the same at a predetermined spacing; d. tightening means carried by said end members and engageable therewith for axial movement relative thereto, said tightening means engageable with said tubular enclosure; e. annular sealing means positioned between said tightening means and an end of said tubular member, whereby said sealing means is compressed to provide a fluid-tight seal between said tubular member, said tightening means, and said end member when said tightening means is moved axially toward the end of said tubular enclosure; and f. each of said end members including means to secure the respective cables thereto.
Claim 3
Dependent Claim
28 words
The cable joint box of claim 1 wherein said means to interconnect said end members include a plurality of crossbars extending between and connected to said end members.
Claim 4
Dependent Claim
