Abstract: A ball and socket coupling that avoids threaded tightening-components instead has telescoped components that are bonded together. Such a coupling has a hollow seat-formed link, a counterpart hollow ball-formed link, and a socket-forming collar. Both the links have fitting extensions. The ball-formed link has a spherical bulb at one end as the seat-formed link has a conforming, spherically-widening seat surface at one end. The socket-forming collar has a centrally apertured web with a conforming spherically-narrowing socket surface at one end of an axially elongated sleeve. The coupling is adapted to be assembled and bonded into solid rigidity by workers in the field with the spherical bulb bonded to and clamped between the seat-formed link's spherically-widening seat surface and the collar's spherically-narrowing socket surface. In addition, the collar's elongated sleeve is bonded internally to the seat-an outer sidewall of the seat-formed link's seat-formed end.

Abstract: An apparatus and method for forming wire bundles from a plurality of wire or cable is provided. A plurality of wires are withdrawn from a rack configured to easily receive and retain a wire spool axial. A driven pulling spool, preferably configured for quick-release coupling to a front loader or other vehicle, is used to pull a cable or bundle along a desired path. Pulling is facilitated by rollers, preferably configured to reduce pulling tension, intermediate endless track tuggers and/or sheaves configured to facilitate coupling to trays or scaffolding. Jacks are described for positioning or holding cables. Preferably rollers or sheaves may be positioned to guide cables along a path above the cable tray or other ultimate position.

Abstract: An apparatus and method for forming wire bundles from a plurality of wire or cable is provided. A plurality of wires are withdrawn from a rack and simultaneously measured by a linear counter. The wires are cut at various positions to provide a bundle having beginning and ending points for the bundle as desired. A driven pulling spool is used to guide the bundle along a desired path. The pulling rope is preferably attached to the bundle by an inflatable bladder. Rollers for guiding the cable include flared end flanges with diameters equal to the shaft diameter of the roller. Clips for holding the rollers to a cable tray provide for ease of repositioning cables.
