Definitions

  • rlhe present invention has reference to javelins and relates more particularly to a new javelin structure the main components of which have approximately the same modulus of elasticity.
  • rlhe present invention eectively obviates this disadvantage by using for the core of the javelin a material the elasticity of which is substantially the same as that of the mantle material.
  • rihe javelin comprises the mantle tube orl shaft a of a suitable wood, into whose interior is closely fitted the core of a material the elasticity coefficient of which is the same as, or at least closely approximates that of, the mantle material.
  • the front shaftend may conventionally be provided with a metal tip 0.
  • lf have found that the so-called Spanish reed (fi/rando (imam), rattan or' cane, is an eminently suitable material for this purpose.
  • the reed rod is decorticated and is then suitably cemented in place in the wooden mantle shaft.
  • Such reed material is light of A weight, is highly flexible, is cheap .and can readily be shaped to fit the mantle bore, and,
