Definitions

  • This invention relates to clockworkv operated fuses for artillery projectiles of the type in whichv the release or"unlocking iof thei strikeris controlled by a rotary settingfmem her, the angular position of which can be set before .firing and which duringtlieflight of the projectile is driven by a clockwork having a power spring in a-direction' o'p'po-j site tothe one in which the setting is effected.
  • the apparatus made in accordance with my present lnvention preferably cons sts 1n;

  • Ehe crown piece 11 is in addition provided its center and cooperating witlrlthe drop. plug v e or iveighted pin'i) 4) to preventup to the m-olnent of firing any; .rotation. of the toothed crownin clockwise direotion,;that is to say for rendering impossible any accidental unlocking of the striker.
  • the hooki28 of the first form is replaced by apin 29 mounted freely in the frame ofthe clockwork.
  • This pin 29 is held in its operative position by a spring 31 and ing this position retains by its'endBOthe nose 24 of the lever 4; spaced from the crown.
  • the latter is v provided with an inclined plane 32-,against which the pawl 26 of the crown operates at the moment in whichitcomes: to registerwith the pin.
  • the internal border of the crown is progressively made thinner as at 33, so. as to constitute on theside ofthe notch an'in clined plane on which the nose of thislever slides.
