Abstract A wire pulling apparatus for use in pulling multi-cable wire through a conduit by means of a mechanical or manual pulling force. The conduit is provided at its entrance opening with a bushing including a matrix of grating elements to conform the wire cables to a predetermined pattern. A first reference for the pattern is established by encasing the wire cables at their leading ends in a basket-like device to which is attached a pulling cable leading through the conduit to the pulling element of the apparatus. The grating elements are rotatably inserted through radial holes provided in the bushing and are held in place by bending or threadably attaching nuts at the periphery of the bushing. Generally vertically oriented grating elements define notches for holding generally horizontally oriented grating elements. Furthermore, the bushing is provided with a smooth lip for preventing destructive contact with the wire cables.

Claim 1
Independent Claim
177 words
A pulling apparatus for multi-cable wire for use with a pulling element to pull said wire through a conduit comprising a basket attached to said multi-cable wire at its leading end to provide a first reference for a pattern for said wire cables, a pulling cable through said conduit affixed at one of its ends to said basket and affixed at the other of its ends to said pulling element and a substantially cylindrical bushing defining a bushing opening and including grating elements at said opening to provide a second reference for said pattern, wherein said bushing further defines radial grating holes, said grating elements leading through said grating holes and establishing a matrix of cable openings at said bushing opening, wherein supporting means for said grating elements are provided of said grating holes and said grating elements are slightly undersized with respect to said grating holes to enable rotation of at least one of said grating elements as said wire cables are pulled thereover to prevent highly frictional contact between said grating elements and said cables.
Claim 2
Dependent Claim
