Carroll; Walter M. Carroll - Web page: https://patentgrep.com/patent/US20140151616A1 ## CPC - H02G 1/04: for mounting or stretching - H02G: INSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINES ## Abstract A system is provided for installing a cable across a medium. The medium traversal system comprises troughs that are connected end to end by connecting bracket and pins. The troughs include opposing sides connected by a bottom surface that form an elongate channel for supporting the traversal and installation of a cable over a medium such as a roadway. The troughs are suspended from a messenger wire by a detachable rolling mechanism that is attached to the sides of the troughs. The troughs are removed by reversing the order of installation. During removal, a lasher is wound around the cable and messenger wire to secure the cable. ## Claims ### Claim 1 A medium traversal system comprising: (a) an elongate trough, said trough comprising opposing sides connected by a bottom surface and said sides extending upward from the bottom surface to an opposing top edge of each side, wherein said top edges define an elongate top opening of a channel along the length of the trough; (b) a rolling mechanism, said rolling mechanism having a roller, and said rolling mechanism is attached above and opposing the top opening of the trough and said rolling mechanism is detachable from the trough whereby the trough is connected to a messenger wire and suspended by arranging the messenger wire between the roller and the trough; (c) a plurality of the troughs are linked end to end and said troughs are suspended from the messenger wire whereby the troughs span across the medium and provide an aerial support for cable within the channel of the troughs. ### Claim 2 (depends on 1) The medium traversal system of claim 1, wherein the rolling mechanism comprises opposed apertures attached to the sides of the trough or integrated into the sides of the trough, and a removable roller pin retains the roller in spaced relation to the bottom surface of the trough by insertion of the roller pin through the roller and the apertures. ### Claim 3 (depends on 2) The medium traversal system of claim 2, wherein the rolling mechanism further includes a bracket connected to the sides of the trough and includes opposing retention arm members extending above the top edge of each side, and said opposed apertures are situated in the opposing retention arm members at a position above the top opening of the trough. ### Claim 4 (depends on 1) The medium traversal system of claim 1, further comprising a connecting bracket comprising on a first end of the trough a pair of opposing outwardly extending pins extending perpendicularly outward from each of the opposing sides of the trough, and, on a second end of the trough, the connecting bracket comprising a pair of opposing connecting arms extending longitudinally from each of the opposing sides of the trough and extending past the second end of the trough and having a pair of opposed apertures in the connecting arms for connection to the pair of opposing outwardly extending pins, whereby the plurality of troughs are linked end to end. ### Claim 5 A method for installing cable across a medium comprising the steps of: (a) providing a messenger wire spanning a medium and attached to a first pole and a second pole, (b) providing a first trough with a roller bracket on both a first end and second end, a hanger on both ends, and bracket pins on the second end, (c) providing a roller for installation on each roller bracket, (d) installing the first trough by hanging the first trough on the messenger wire by the hangers and then installing the rollers on the roller brackets, (e) providing a plurality of a second trough with a connecting bracket on a first end, a roller bracket and a hanger on a second end, and bracket pins the second end, (f) installing the second trough by hanging the second trough on the messenger wire by the hanger and connecting the connecting bracket of the second trough to the bracket pins of the first trough and then installing the roller provided for each roller bracket on the roller bracket of the second trough, (g) repeating the installing of the second trough until the medium is traversed by the plurality of troughs using the plurality of the second troughs by installing each additional second trough by hanging the second trough on the messenger wire by the hanger and connecting the connecting bracket of the second trough to the bracket pins of the previous installed second trough and then installing the roller provided for each roller bracket on the roller bracket of the additional second trough, (h) pulling a cable through the troughs to traverse the medium, (i) attaching a lasher around the cable and the first end of the first trough, and (j) removing the troughs from the messenger wire in the reverse order that they were installed while pulling the lasher across and winding the lasher around the cable and the messenger wire to secure the cable to the messenger wire.
