Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
176 words
Apparatus for securing swage sleeves upon a wire rope having a splice thereon configured to form a sling at the end of such wire rope, said apparatus comprising: a supporting structure; means movably mounted on said supporting structure for securing and capturing a swage sleeve, said securing and capturing means being configured to permit the passage of an end of wire rope therethrough such that such end of such wire rope may be passed through such swage sleeve to be spliced and formed into a sling loop; means positioned on said supporting structure for clamping a portion of such wire rope on the other side of said securing and capturing means from such wire rope sling loop; and means for automatically forcibly moving said securing and capturing means, and such swage sleeve contained therein, in a direction away from said clamping means and toward such sling loop on such end of the wire rope for forcing the spliced portion into such swage sleeve such that a stronger splice is realized when such swage sleeve is swaged.
Claim 2
Dependent Claim
176 words
Apparatus for securing swage sleeves upon a wire rope having a splice thereon configured to form a sling at the end of such wire rope, said apparatus comprising: a supporting structure; means movably mounted on said supporting structure for securing and capturing a swage sleeve, said securing and capturing means being configured to permit the passage of an end of wire rope therethrough such that such end of such wire rope may be passed through such swage sleeve to be spliced and formed into a sling loop; means positioned on said supporting structure for clamping a portion of such wire rope on the other side of said securing and capturing means from such wire rope sling loop; and means for automatically forcibly moving said securing and capturing means, and such swage sleeve contained therein, in a direction away from said clamping means and toward such sling loop on such end of the wire rope for forcing the spliced portion into such swage sleeve such that a stronger splice is realized when such swage sleeve is swaged.
Claim 3
Dependent Claim
72 words
The apparatus according to claim 1 in which said securing and capturing means is movable from a first position, in which the swage sleeve contained therein is in a frictionally fitted status with the splice of such sling loop on such wire rope, to a second position in which the swage sleeve contained therein is forced onto such splice with sufficient force to wholly contain such splice thereby forming a stronger splice.
Claim 4
Dependent Claim
51 words
The apparatus according to claim 1 in which said securing and capturing means is further configured including means formed as a portion thereof which channels the spliced portion of such wire rope, along with its loose and ragged ends into said securing and capturing means and, subsequently, into such swage sleeve.
Claim 5
Dependent Claim
70 words
The apparatus according to claim 1 in which said securing and capturing means is configured generally as a coffin, having a bottom portion and a top portion hinged thereto, both said bottom and top portions having substantially equal shapes such that at least a portion of the interior of said securing and capturing means is complementary shaped relative to such swage sleeve when said top and bottom portions are joined.
Claim 6
Dependent Claim
119 words
The apparatus according to claim 1 in which said securing and capturing means is configured generally as a coffin, having a bottom portion and a top portion hinged thereto, both said bottom and top portions having substantially equal shapes such that at least a portion of the interior of said securing and capturing means is complementary shaped relative to such swage sleeve when said top and bottom portions are jointed, said securing and capturing means having stops located therein for preventing substantial movement of such swage sleeve within said securing and capturing means when the latter is in either its opened state, and said top and bottom portions are hinged away from each other, or in their closed state.
Claim 7
Dependent Claim
39 words
The apparatus according to claim 5 in which said securing and capturing means further includes releasable locking means for locking both said top and bottom portions together with a swage sleeve therein prior to actuation of said moving means.
Claim 8
Dependent Claim
22 words
The apparatus according to claim 1 in which said means for automatically forcibly moving said securing and capturing means is pneumatically actuated.
Claim 9
Dependent Claim
14 words
The apparatus according to claim 1 in which said clamping means is pneumatically actuated.
Claim 10
Independent Claim
143 words
A method of automatically securing swage sleeves on wire rope sling splices, said method comprising: fitting a swage sleeve within a holder complementarily configured relative to the swage sleeve; threading the end of a wire rope, intended to be spliced into a sling, into the holder and through the swage sleeve contained therein; forming the wire rope end into a spliced sling; clamping the wire rope at a point on the opposite side of the holder from the spliced sling; automatically moving the holder, and the swage sleeve contained therein, in a direction away from the point at which the wire rope is clamped and toward the splice formed on the sling, thereby forcing the swage sleeve onto the splice of the wire rope; and releasing the swage sleeve from the holder and unclamping the wire rope in preparation for a swaging operation.
Claim 11
Independent Claim
143 words
