Abstract
Abstract A cable lock and seal device which comprises a flexible cable and an enclosure fixedly secured to one end of the cable. A passage extends through the enclosure and is proportioned slidably to receive the distal end portion of the cable therethrough. A wedge element and a disk-shaped jam element are sealed within the enclosure, the wedge element including a ramp surface disposed at a small angle with respect to the passage and laterally spaced apart therefrom. The jam element is frictionally engaged between the ramp surface and cable portion whereby, movement of the cable through the passage in one direction causes movement of the jam element laterally away therefrom and movement of the cable in a direction opposite the aforementioned direction causes movement of the jam element laterally toward the cable to thereby jam the cable between the passage walls and the jam element so as to prevent further movement thereof in that direction.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
227 words
A cable lock and seal device comprising a flexible cable, an enclosure fixedly secured to one end of said cable, said enclosure including inner and outer shells, said inner shell having parallel spaced-apart side walls and part-cylindrical end walls, the top and bottom ends thereof being open, said outer shell including parallel spaced-apart side and end walls and open top and bottom ends, said inner shell being slidably received in said outer shell and having the end walls thereof extending outwardly from the top and bottom ends of said inner shell, said part-cylindrical walls and said outer shell defining therebetween first and second passages, respectively, said cable end being clamped in said second passage, said first passage being proportioned to slidably receive the distal portion of said cable therethrough, a wedge element and a disk-shaped jam element sealed within said enclosure, said wedge element including a ramp surface disposed at a small angle with respect to said second passage and laterally spaced apart therefrom, said jam element being frictionally engaged between said surface and said portion, whereby, movement of said portion through said first passage in one direction causes movement of said jam element laterally away therefrom and movement of said portion in the direction opposite said one direction causes movement of said disk laterally toward said portion to thereby jam Said portion within said first passage.
Claim 2
Dependent Claim
227 words
A cable lock and seal device comprising a flexible cable, an enclosure fixedly secured to one end of said cable, said enclosure including inner and outer shells, said inner shell having parallel spaced-apart side walls and part-cylindrical end walls, the top and bottom ends thereof being open, said outer shell including parallel spaced-apart side and end walls and open top and bottom ends, said inner shell being slidably received in said outer shell and having the end walls thereof extending outwardly from the top and bottom ends of said inner shell, said part-cylindrical walls and said outer shell defining therebetween first and second passages, respectively, said cable end being clamped in said second passage, said first passage being proportioned to slidably receive the distal portion of said cable therethrough, a wedge element and a disk-shaped jam element sealed within said enclosure, said wedge element including a ramp surface disposed at a small angle with respect to said second passage and laterally spaced apart therefrom, said jam element being frictionally engaged between said surface and said portion, whereby, movement of said portion through said first passage in one direction causes movement of said jam element laterally away therefrom and movement of said portion in the direction opposite said one direction causes movement of said disk laterally toward said portion to thereby jam Said portion within said first passage.
Claim 3
Dependent Claim
23 words
The device of claim 1 wherein said surface is generally flat and laterally serrated, said jam member having a cylindrical, laterally serrated surface.
Claim 4
Dependent Claim
15 words
The device of claim 1 wherein said cable is braided and has an irregular surface.
Claim 5
Dependent Claim
24 words
The device of claim 3 wherein said small angle is equal to or less than 10* with respect to the axis of said passage.
Claim 6
Dependent Claim
36 words
The device of claim 4 wherein said first passage includes a wall disposed diametrically opposite said jam element, said wall having an indentation thereon extending inwardly of said passage, said portion engaging and being deformed thereby.
Claim 7
Dependent Claim
91 words
The device of claim 5 where said wedge element is received within said inner shell adjacent said second passage and extends between said end walls of said outer shell, said wedge element further including a pair of flanges adjacent the opposite ends thereof, respectively, said flanges abuttingly engaging said end walls, and a passage wall disposed in generally parallel, spaced-apart relationship to said semi-cylindrical wall adjacent said second passage, said passage wall having a tooth means thereon extending inwardly of said second passage for deforming and clampingly engaging said cable end.
