Definitions

  • Patented ug. 2l, 1923 Patented ug. 2l, 1923.
  • the invention relates t'o wire ropesv and has for its main object to p'rovide'a rope which will be 'practically immune from elongation under stress.
  • the rope according to the invention comprises a pluralityv of parallel laid wires of any desired Vsection which are mechanically compressed vtogether and are then held together by a. serving of metallic tape wound on hot and under tension, the tape beingheated during application as by passing an electric current therethrough, or by other suitable heating means.
  • the rope may be composed of separate wires, or of a single wire wound to form a plurality of convolutions and joined at the ends, the convolutions being,l lthen closed together and bound by" the tape intermediate of the ends so that loops are formed at the extremities.
  • Fig. l shows a length of rope partly in longitudinal section and partly in elevation.
  • Fig. 2 is a cross section on the line 2 2 of Fig. l.
  • Fig. 3 shows in longitudinal section a rope formed of a single wire wound to form a plurality of convolutions and having loops at the ends, and
  • a designates the several parallel wires forming the core of the rope over which is wound on hot the serving ZJ the latn ter being preferably of stepped section as shown best in Fig. 4, each convolution of the metallic tape overlapping the preceding convolution. To allow for expansion and contraction, a small clearance is provided during the winding as shown at c.
  • the metallic tape b is wound on hot, the .heating being preferably effected :by causing an electric current to pass through it, and it is applied under tension in order to bind the compacted Wires as tightly as possible before the cooling down of the metallic tape completes the process by contraction.
  • the metallic tape Z) also forms a watertight 'casing 'for the vwires d' in addi'- ltion tofitsbindinggaction.' Y
  • portions 7c icl thusproc'luced are then bound together bythe metallic tape inthe manner' above ,describad,l the winding terminating i such wdistfafnv'ce fronrthfe'erfds as to leave' loops spliceis effected' by means of split come rcamped togeter by 'bleigw grip' the rope 'and the ends of the metallic' Atape b.
  • the latter is bell mouthed as shown at It, and a seal is produced by brazing or filling the bell mouth with a suitable medium suchA as white metal.
  • a rope comprising a core consisting of flattened convolutions of metal wire and a metal ribbon shrunk in spirals round said convolutions.
  • a rope comprising a core consisting of parallel metal wires and a metal ribbon shrunk in partly overlapping spirals round said parallel metal wires.
  • a rope comprising a core consisting of Y flattened convolutions of metal wire, said convolutions lying parallel 4to and adjacent one another except at their ends forming loops, and a metal ribbon shrunk in spirals round said parallel portions o-f said convolutions of said convolutions, flexible wires wound round the portions of said convolu tions forming said loops, and clamps surl rounding the junction of said loops so cov- Y ered with said parallel portions of said convolutions so covered.
  • a rope comprising a core: consisting of continuous Hattened convolutions of metal Wire, said convolutions lying parallel to and adjacent one another except at their ends forming loops, a metal ribbon shrunk in ⁇ partly overlapping spirals round said par- Y preventing entry of YWater between saidr clamps and the surfaces surrounded thereby.
