Abstract
Abstract The disclosed termination appliance for a load bearing cable or the like is particularly suited to extraordinarily high load applications. The appliance comprises a first egg-shaped protuberance defining member secured to the cable by helically preformed elements wrapped in tightly encircling relation about the member and extending in gripping relation along the cable in opposite directions therefrom. A second member of a conforming contour is applied in overlying relation to the first member and a second set of helically preformed elements are applied in encircling overlying and gripping relation to the second member and the first set of helical elements to further enlarge the protuberance. The described sub-assembly is situated within a housing having contoured sidewalls for conformably seating the enlarged protuberance and a narrowed aperture for passing the cable. The concentric protuberance structures cooperate to share the load on the cable. Other features are disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
220 words
A termination appliance for a load bearing cable or the like, comprising: first protuberance means comprising a first member applied about said cable and a first set of helically preformed elements of a predetermined internal diameter and pitch length wrapped in tightly encircling relation about said member and extending along said cable for respective predetermined distances in either direction therefrom for securing said first member to said cable so as to form a protuberance on said cablE in the region of said first member; second protuberance means comprising a second member composed of a plurality of sections applied in overlying relation of said first member and a second set of helically preformed elements of a predetermined internal diameter and pitch length wrapped in tightly encircling relation about said second member in overlying relation to said first set of helically preformed elements and extending along said cable for respective predetermined distances in either direction therefrom for securing said second member to said first set of rods so as to further enlarge said first protuberance; and housing means for seating said enlarged protuberance with said first and second protuberance means adapted for sharing the load on said load bearing cable, said housing means having an aperture of a diameter intermediate that of said cable and said enlarged protuberance for passing said cable.
Claim 2
Dependent Claim
220 words
A termination appliance for a load bearing cable or the like, comprising: first protuberance means comprising a first member applied about said cable and a first set of helically preformed elements of a predetermined internal diameter and pitch length wrapped in tightly encircling relation about said member and extending along said cable for respective predetermined distances in either direction therefrom for securing said first member to said cable so as to form a protuberance on said cablE in the region of said first member; second protuberance means comprising a second member composed of a plurality of sections applied in overlying relation of said first member and a second set of helically preformed elements of a predetermined internal diameter and pitch length wrapped in tightly encircling relation about said second member in overlying relation to said first set of helically preformed elements and extending along said cable for respective predetermined distances in either direction therefrom for securing said second member to said first set of rods so as to further enlarge said first protuberance; and housing means for seating said enlarged protuberance with said first and second protuberance means adapted for sharing the load on said load bearing cable, said housing means having an aperture of a diameter intermediate that of said cable and said enlarged protuberance for passing said cable.
Claim 3
Dependent Claim
59 words
The termination appliance of claim 1 in which said first member is of an internal diameter for freely passing said cable and in which said second member is composed of a pair of mating sections for only partially encompassing said first protuberance so that pressure on said second member is translated to said first set of helically preformed elements.
Claim 4
Dependent Claim
39 words
The termination appliance of claim 2 in which said first set of helically preformed elements extend in opposite directions from said first member by respective distances at least equal to those of said second set of helically preformed elements.
Claim 5
Dependent Claim
24 words
The termination appliance of claim 3 in which said first and second sets of helically preformed elements are of an opposite hand of lay.
Claim 6
Dependent Claim
22 words
The termination appliance of claim 4 in which said second member extends along said cable a greater distance than said first member.
Claim 7
Dependent Claim
55 words
The termination appliance of claim 5 in which said first member includes a cylindrical aperture corresponding to the diameter of said cable and is of an ellipsoidal exterior contour and in which said second member is of a generally ellipsoidal interior contour for conforming to said protuberance and is further of an ellipsoidal outer contour.
Claim 8
Dependent Claim
46 words
The termination appliance of claim 6 in which said housing means includes an open receiving end of a diameter exceeding the maximum diameter of said enlarged protuberance, a restraining end having sidewalls for seating said protuberance and a housing passageway interconnecting said receiving and restraining ends.
Claim 9
Dependent Claim
41 words
The termination appliance of claim 7 and further including retainer means received within said housing means passage in threaded engagement with said housing and in conforming engagement with that portion of said enlarged protuberance opposite said restraining end of said housing.
Claim 10
Dependent Claim
23 words
The termination appliance of claim 8 and further including a clevis member threadably connectable to said housing means at said open receiving end.
Claim 11
Dependent Claim
37 words
The termination appliance of claim 1 in which said housing means comprises a pair of mating half-sections cooperatively defining a contoured receiving portion for conformably seating said enlarged protuberance and having an aperture for passing said cable.
Claim 12
Dependent Claim
26 words
The termination appliance of claim 1 in which said first set of helical elements is of a like hand of lay as that of said cable.
Claim 13
Dependent Claim
26 words
The termination appliance of claim 1 in which said cable and said first and second sets of helical elements are of a like hand of lay.
