Definitions

  • the present invention relates to springs for mechanical time fuses with clock work.
  • the tension springs heretofore used for the clock work of such fuses were commonly clock springs, that is to say, thin spirally wound steel strips rendered elastic by a hardenin g and tempering process.
  • Such springs which occasionally break even in constantly working clock works where they are carefully protected from severe shock, owing to the difficulty in hardening them uniformly, afford only slight security against breaking when used for the clock work of mechanical time fuses.
  • the causes of breakage reside in the peculiar strains to which the tension spring of the clock work of mechanical time fuses, are exposed.
  • the invention has for its purpose to provide mechanical time fuses with clock work, which are fully dependable.
  • This purpose is attained, according to the invention, by producing a spiral spring from hard drawn steel wire whose natural .elasticity is further increased by additional mechanical working in the cold state, such asby drawing, rolling or hammering, and furthermore in doing this, to change the section of the spring wire .from round to flat with the greater .dimension in the direction of the axis of the fuse and projectile, that is, perpendicular to the plane of spring coil.
  • Figure 1 shows the assembly of a mechanical time fuse with clock work as frequently produced of late
  • Fig. 2 shows on a large scale a part of the tension spring for the same
  • Fig. 3 1s a section on the line 33 of Fig. 2.
  • A designates the tension spring of the clock work which is arranged in the housing B.
  • the spring consists of a. wire of elongated round form in cross section, which is produced from round wire by drawing or rolling in the cold state and thereby simultaneously subjected to the working necessary for increasing its elasticity.
