Abstract
Abstract A hollow conical line-pulling carrier which is connected with the line being pulled by a connection on the interior of the carrier spaced upwardly from the base of the cone for pulling a messenger line through electrical conduit. The conical portion is made of extremely light-weight plastic, permitting it to be either blown through the conduit or sucked therethrough. Because the connection to the cone is spaced upwardly from the base, it permits the base of the cone to adjust to debris, imperfections, or water in the conduit without having the cone collapse and thus permit the messenger line to continue to be pulled through the conduit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A carrier for pulling a messenger line through conduit comprising a single, unitary, lightweight, flexible, plastic cone whose base is approximately the same diameter as the interior of the conduit being traversed, a plurality of flexible strands, each of said strands being attached at one of its ends to, and each of said strands extending inwardly directly from, the interior of said cone only at a location essentially parallel to the base of said cone and spaced between said base and the apex of said cone, said strands being equi-spaced around the interior of said cone, the other end of each of said strands being joined together and attached to means to which a messenger line may be attached.
Claim 2
Dependent Claim
119 words
A carrier for pulling a messenger line through conduit comprising a single, unitary, lightweight, flexible, plastic cone whose base is approximately the same diameter as the interior of the conduit being traversed, a plurality of flexible strands, each of said strands being attached at one of its ends to, and each of said strands extending inwardly directly from, the interior of said cone only at a location essentially parallel to the base of said cone and spaced between said base and the apex of said cone, said strands being equi-spaced around the interior of said cone, the other end of each of said strands being joined together and attached to means to which a messenger line may be attached.
Claim 3
Dependent Claim
35 words
The carrier of claim 1 wherein the end of each of said strands which is attached to the interior of said cone is attached closer to said base than to the apex of said cone.
Claim 4
Dependent Claim
19 words
The carrier of claim 1 wherein the means to which a messenger line may be attached comprises a ring.
Claim 5
Dependent Claim
127 words
A carrier for pulling a messenger line through conduit comprising a single, unitary, lightweight, flexible, plastic cone whose base is approximately the same diameter as the interior of the conduit being traversed, a flexible conical-shaped member having slots equi-spaced by elements extending along the surface of said conical-shaped member in a direction from said base toward said apex of said conical member, the base of said conical-shaped member being attached to the interior of said cone only at a location essentially parallel to the base of said cone and spaced between said base and the apex of said cone, the elements being equi-spaced around the interior of said cone, the apex of said conical-shaped member being attached to means to which a messenger line may be attached.
Claim 6
Dependent Claim
127 words
A carrier for pulling a messenger line through conduit comprising a single, unitary, lightweight, flexible, plastic cone whose base is approximately the same diameter as the interior of the conduit being traversed, a flexible conical-shaped member having slots equi-spaced by elements extending along the surface of said conical-shaped member in a direction from said base toward said apex of said conical member, the base of said conical-shaped member being attached to the interior of said cone only at a location essentially parallel to the base of said cone and spaced between said base and the apex of said cone, the elements being equi-spaced around the interior of said cone, the apex of said conical-shaped member being attached to means to which a messenger line may be attached.
Claim 7
Dependent Claim
19 words
The carrier of claim 4 wherein the means to which a messenger line may be attached comprises a ring.
Claim 8
Dependent Claim
17 words
The carrier of claim 4 wherein said elements are strands separating open spaces in said conical-shaped member.
