Definitions

  • the accuracy of the aim will be detrimentally aiected as the path oi the harpoon or like projectile is reduced and will vary considerably when a hard or tightly twisted line is used.
  • the position of the cable in the centre of the strand is ensured by one or more layers or servings of yarn laid around the cable and enclosed in a wrapping of ribbon or yarn, the said layer or layers of yarn being thereby attached to the cable in such a manner that .the cable cannot break through the layer enclosing the same, and hencethedanserotabreakintheconductoris
  • the fore-runner oreliminated the rope may be twisted quite loosely whereby a greater range and a greater accuracy of aim is obtained.
  • the diameter of the rope may be reduced considerably as compared with fore-runners 5 provided with electric cable as hitherto used, where a large diameter was necessary in order to obtain a thick hemp covering for securing the cable inside the same. This reduction of the diameter also tends to increase the range and the 10 accuracy of aim.
  • said ribbons or yarns for enclosing the layer or layers of yarn and the cable may be of cotton, hemp, jute, impregnated paper or other suitable material and may be laid so close that 15 the windings or turns are in contact or overlap each other, or a space may be left between the individual windings or turns.
  • Figure 1 shows a piece of a fore-runner with three strands and an electric cable inside each of the strands. An end of one of the strands is unwound in order to show the disposition of the cable therein. 25
  • Figure 2 shows a section o! this fore-runner.
  • I is the electric cable around which a yarn layer or serving 3 is laid. Around the same is next wound a textile ribbon 2 which holds together the cable and the yarn layer 3.
  • the ribbon 30 in the example shown is wound in the same direction as the yarn layer 3, but it may also be wound in the opposite direction.
  • yarn may be used instead of ribbon for winding around the cable and yarn'layer, and 35 this ribbon or yarn may be arranged around two or more layers of yarn laid next to the cable.
  • a harpoon line comprising one or more strands, at least one of said strands comprising a water- 40 prooi insulated electric conductor, a plurality of yarns wound helically to form a layer about said insulated conductor, a wrapping, surrounding said insulated conductor and-said layer of yarns, and a plurality of yarns helically wound about said l conductor, said rst yarn layer and said wrapplus.
