Definitions

  • the object of the present invention is to increase the safety with which hand grenades can be manipulated by providing them with an igniting plug, the striker of which is liberated by a catch lever or an equivalent member only after the latter has effected a movement of fairly large amplitude, say for example a quarter of a turn, without this displacement influencing in any way 25 the degree of tension of the striker spring.
  • This displacement will be produced either under the effect of a removal or by a ballistic action, for example, under the action of inertia, centrifugal force, etc.
  • the tail of the striker is gripped in a sliding cover or cap engaged by the catch lever and applied her- 50 metically upon the upper face of the igniting plug by the striker spring.
  • Figure 2 is a partial front view thereof.
  • Figure 3 is a plan view with an oblique section through the catch lever. 5 ,As in the known hand grenades, the body I of the plug is screwed upon the body of the hand grenade and comprises the exploder holder 2, carrying the priming cap 3, the relay 4 and the detonator 5.
  • the striker 6 having a spherical head and a. conical shaped part I which bears upon a correspondingly shaped wall of a chamber II' formed in a cover or cap Il mounted upon the body with the interposition of 5 a joint I2.
  • the conical tail 7 is gripped between the edge 9 of the body I and the edge In of the chamber II of the cover or cap II.
  • the spring 8 seated on an annular shoulder in the hollow of the body I exerts a pressure upon the striker I which also has the eflect of pressing the cover or cap I I tightly against the upper face of the body I and of urging it at the same time to slide towards the left.
  • the cover I I is locked in the cooked position by a catch lever I! which encloses the cover, and has upon each of its lateral faces a beak or hook I8 adapted to engage a lug I9 rigid with the cover or cap II ( Figure 3).
  • the line aa joining the points of contact a of the hook l8 with the lugs I9 constitutes the pivoting axis of the lever ll.
  • the body I is provided externally with a circular surface 20 having its centre on the line aa ( Figure 3) and forming a track for a roller 2
  • aa Figure 3
  • a pin I6 locks the lever I1 in known manner in order to permit the grenade to be handled with safety.
  • may be mounted on'the body I of the ,plug,while the circular surface 20 will be provided upon or in the catch lever l1.
  • a spring pressed striker mounted in said plug body and having a conical upper part'gripped in its cocked position in the said chamber between an edge of said cover'within said chamber and an 7 the spring 8, and permits the striker 6 also to re- 7 spond to the pressure of the spring 8 and fire the primer 3.
  • a catch member locked on the plug body by a safety pin, and adapted to enclose with its upper part the sliding cover, said catch member having notches cooperating with lugs providedon said sliding cover to hold the catch member in the cocked position, a. circular surface formed externally on the plug body and constituting a track, and a revoluble member carried by the catch member engaged by said track.
  • An ignition plug for hand grenades comprising a body member having an ignition chamber open at one end and containing a priming cap, an annular ledge adjacent said opening, a hollow cap covering said opening and provided with a bevelled edge near its center, a striker having an enlarged head and a cone-shaped tail adapted to engage between said bevelled edge of the cap and said ledge in asse'mbledposition, a double acting spring inserted between said ledge and said striker head, whereby said striker isheld in cocked posi-
