Definitions

  • This invention relates to a communications cable which is provided with a fabric sleeve installed on the cable at the factory or in the field just before the cable is installed into a conduit.
  • a fabric sleeve installed on the cable at the factory or in the field just before the cable is installed into a conduit.
  • an apparatus to be introduced into a conduit made in accordance with the present invention includes a cable having a length and a pliant sleeve positioned around the cable for substantially the entire length.
  • the present invention also relates to a method of introducing a longitudinally extending cable into a conduit which includes the steps of wrapping a pliant material around substantially the entire length of the cable and thereafter introducing the wrapped cable into the conduit.
  • Fig. 1 is a schematic view showing the manner in which a conventional cable is wrapped with a fabric sleeve and inserted in to conduit.
  • Fig. 2 is an end view of a fabric sleeve made in accordance with the present invention.
  • Fig. 3 is a fragmentary top plan view of the sleeve of Fig. 2.
  • Fig. 4 is a sectional view of a cable and sleeve of the present invention showing the sleeve of Figs. 2 and 3 wrapped around the cable.
  • Fig. 5 is an end view of an alternative version of a fabric sleeve made in accordance with the present invention.
  • Fig. 6 is a fragmentary top plan view of the sleeve of Fig. 5.
  • Fig. 7 is a sectional view of a cable and sleeve of the present invention showing the sleeve of Figs. 5 and 6 wrapped around the cable.
  • Fig. 8 is an end view of another alternative version of a fabric sleeve made in accordance with the present invention.
  • Fig. 9 is a sectional view of a cable and a sleeve of Fig. 8 wrapped around the cable.
  • Cable 11 is a conventional item and, as such, typically includes a plurality of conductive wires encapsulated within a plastic jacket.
  • Sleeve 12 may be made of a pliant material such as the fabric described in U.S. Patent No. 6,421 ,485, and can be in the form of a longitudinally extending sheet 13 of material having a fastening system formed on opposed edges thereof.
  • Such a system could be glue or some other adhesive, or it could be the VELCRO® hook and loop fastening system shown.
  • one edge on one side of sheet 13 may be provided with a hook connector 14 and the opposed edge on the other side of sheet 13 may be provided with the companion loop connector 15.
  • the width of the sheet between the connectors 14 and 15 generally corresponds to the circumference of cable 11 such that when sleeve 12 is positioned on cable 11 , as shown in Fig. 4, connectors 14 and 15 may engage each other to tightly hold sleeve 12 on cable 1 1.
  • FIG. 7 An alternative cable and sleeve assembly is shown in Fig. 7 and generally indicated by the numeral 20.
  • the conventional cable 11 is shown as receiving a spring-loaded sleeve of fabric or thin plastic material generally indicated by the numeral 21 which is formed of a sheet 22 having opposed edges 23 and 24. As shown, edge 24 circumferentially overlaps a portion of sheet 22 to provide a tight grip on cable 11.
  • Fig. 9 Another alternative cable and sleeve assembly is shown in Fig. 9 and generally indicated by the numeral 30.
  • the conventional cable 11 is shown as receiving a fabric sleeve generally indicated by the numeral 31.
  • sleeve 31 may be formed of a pliant or fabric material and provided in the form of a longitudinally extending sheet 32. As best shown in Fig. 8, one side of sheet 32 can be provided with an adhesive 33.
  • the width of sheet 32 generally corresponds to the circumference of cable 1 1 such that when sheet
  • the cable sleeve assemblies 10, 20, or 30 may be manufactured and assembled at the factory and shipped on rolls to the underground conduit construction site. Typically, such rolls could have two thousand or more feet of assemblies 10, 20, or 30 thereon to be played out and inserted into an underground conduit by conventional systems.
  • a sleeve 12 or 21 could be applied to the cable 11 in the field as schematically shown in Fig. 1.
  • a roll 40 of cable 1 1 and a roll 41 of a sleeve 12 or 21 are provided at the site for installation into a conduit.
  • the cable 11 and sleeve 12 in the condition shown in Figs. 2, 3 or 8 or the sleeve 21 in the condition shown in Figs. 5 and 6, are fed to a device 43.
  • device 43 is a folder which wraps sleeve 12 or 31 around cable 11 as they simultaneously pass through device 42 to form assembly 10.
  • device 42 can be a spreader which opens sleeve 21 so that the cable 1 1 may pass between edges 23 and 24. The spreader then releases sleeve 21 to allow sleeve 21 to snap back to its original condition and now forming assembly 20.
  • the resulting cable and sleeve assembly 10, 20 or 30 may then be pulled into a conduit by a conventional rope or pull tape or may be provided to a conventional cable pushing/blowing machine 43 which includes tractor-like devices 44 to grip assembly 10 or 20 and push it into and through a conduit (not shown) to the right in Fig. 1.
  • the pushing movement of devices 44 can be assisted by the blowing of air into the conduit as is known in the art.
  • assemblies 10, 20 or 30 By wrapping a cable with a pliable material which has less friction than the jacket of a cable, assemblies 10, 20 or 30 can be more easily installed into a conduit which does not have an innerduct therein. As a result, the cost of the innerduct is saved. On the other hand, if the conduit does have an innerduct already positioned therein, the cable sleeve assemblies 10, 20 or 30 are also more easily inserted into a compartment of the innerduct.
  • a cable sleeve assembly 10, 20 or 30 manufactured and used as described herein accomplishes the objects of the invention and otherwise substantially improves the art.
