Definitions

  • Pyrotechnic devices exist, which are intended for practice purposes, such as hand grenades having a body which consists, like a practice signal cartridge, of powder, such as clay powder, which is surrounded by a waterproof, thin coveringsuch as plastic, and is provided with aspring-loaded cap which is secured on the grenade during non-use, and which cooperates with an igniting device consisting of a friction igniter, and is associated with legs or limbs acting as leaf springs.
  • grenades are so constructedthat, when the cap is placed on'the grenade body, the legs of the cap lie against the body and elastically clutch it, but only in such a manner that their elastic clutching force will be overcome by the force of a spring which, after a safety device has been removed, and after the hand of the thrower has released the legs in throwing the grenade, hurls the cap away from the body and operates thefriction igniter.
  • Such hand grenades have not proven entirely satisfactory in actual practice, especially because premature ignition can be produced by the premature release of the cap due to the great deformability of the body.
  • the subject of the present invention is pyrotechnic devices, such as hand grenades, for practice purposes, which are filled in a known manner with powders, colored liquids or the like, and are provided with a spring loaded, self-ejecting cap which cooperates with an igniting device characterized by a plurality of shell segments, preferably two half shells, articulated on the cap and held in assembled relation so as to form a shell by the safety pin, while 4 at the same time the shell segments are urged to an open or spread condition byspring means which, upon removal of the pin, become operative to spread the shell segments.
  • the shell segments are held in the proper assembled relation by guiding means provided on their sides and engaging one another.
  • the signal material is in a waterproof, thin container, preferably made of an elastic plastic such as'polyethylene, or of impregnated paper or fabric.
  • the igniter can be a tearing, percussion or friction igniter. All parts, with the exception of the cap ejecting spring and certain parts of the igniter, can be made of plastic.
  • the hand grenade accordingto the present invention is a solid body which does not differ in appearance from a standard hand grenade. Before throwing, it is armed in the customary manner, in that the throwing hand envelops the grenade body while the other hand pulls out the safety pin. As long as the shell segments or two half shells remain enveloped by the throwers hand, the igniter cannot be operated, i.e., the hand grenade canbe held in the hand for an un- Not until the grenade is thrown do the half shells fly apart under the effect of coil or leaf springs, the cap being drawn off of the grenade body under the influence of a helical spring, so that the igniter simultaneously goes into operation. Ignition is started at the moment the shells fly apart and is carried on through a delay charge, so that the actual explosion of the plastic body depends only on the burn ing time of the delay charge.
  • the invention provides a grenade including an outer casing, a throw-off cap mounted on one end of the casing, and means biasingthe cap, urging it off the casing.
  • This biasing means can be arranged so that it works axially of the casing, in the conventional manner for operation of a helical spring utilized with a throw-off cap.
  • the grenade includes a removable retainer means for holding the capmounted on the casing against the force of the biasing means.
  • the arms can be shell segments which together form a protective covering for the casing.
  • Spring means which work radially of the casing and urge the arms away from the casing are provided'
  • the spring means can be leaf springs connected to the throw-off cap.
  • the grenade also includes removable retainer means holding the arms, or shell segments, about the casing in opposition to the force ofthe radially acting springs.
  • a pin as is conventionally used on grenades, can serve as the means for restraining the cap against the pressure of the cap biasing means, and also as the means for restraining the force of the radially working springs.
  • shell segments are provided, they are preferably in abutting relation along axially extending edges thereof, and means are disposed along abutting portions of the segments for aligning the segments to provide a uniform protective covering for the casing.
  • FIG. 1 is an elevated view in cross-section of a device according to the invention.
  • FIG. 2 is taken along line 2-2 in FIG. 1.
  • 1 indicates the protective shell made up of two half shells 1a and 1b, 2 the hand grenade casing, 3 the filler, 4 the delay charge, 5 the explosive charge, 6 the plug, '7 the throw-off cap, 7a the leaf spreading springs, 8 the safety pin, 9 the pull ring, 16 the helical spring for ejecting the cap, 11 the tearing igniter, and .12 the fastening of the igniter tearing wire.
  • the leaf springs 7a can be integral with the cap 7 and need only extend about a portion of the circumference of the shell 3.
  • the half shells are hinged to the cap by. hinge connectiions 13.
  • the pin 8 clamps the shell halves 1 together and biases the leaf springs 7a 30 that, upon removal of the pin and release of a hand grip on the half shells 1, the leaf springs throw the half shells out from the grenade casing 2, while simultaneously the helical spring 10 thrusts the cap off the grenade body, so that the cap and half shells are thrown olf and the ignition is effected.
  • Half shell 1a is provided with step edges 14 along each of the axially extending boundaries thereof and half shell 1! is provided with tongues 15, which complement the step edges 14 of shell half It: so that suitable assembled relation of the shellhalves is obtained.
  • the half shells are provided in aligned relation so that together they form a uniform covering for the casing 2.
  • the pin 8 passes through fitting 16, which is mounted on the casing 2, and through the cap 7, so that it serves as a retainer for the cap. Further, pin 8 is in abutting relation with the extensions 17 of the half shells la and 1b, and thus the pin serves to restrain movement of the half shells in response to urging of the leaf springs 7a.
  • the fitting 16 can consist of two parts 16a and 16b which are screwed together or otherwise connected but it can also be made in one single piece.
  • the plug 6 is fastened in the casing 2 by means of a fixed press fit or a screw connection whilst the fitting 16 with its attachment 160 is held in plug 6 only by means of a light press fit or sliding fit so that when the casing 12 is ejected by the force of the helical spring it), the casing 2 together with plug 6 are disconnected from the remaining parts.
  • cap '7 and the leaf springs 7a in one piece from polypropylene by injection moulding. It is advisable to have the leaf springs 7a rectilinear and located in such a way that subtended leaf springs form an angle approximately of 75 to 90.
  • the half shells 8 preferably also made from polypropylene, had a wall thickness of 1 mm. in this case.
  • a hand grenade comprising:
  • (c) means biasing the cap, urging it off the casing
  • Hand grenade according to claim 1 and a fitting on said casing, the throw-off cap being mounted on the fitting, and extensions on said arms, a removable pin extending through said cap and said fitting serving as the first-mentioned retainer means, and abutting with said extensions serving as the second-mentioned retainer means.
  • a hand grenade comprising:
  • (0) means biasing the cap, urging it off the casing
  • Hand grenade according to claim 3 said shell segments being in abutting relation, and means disposed along abutting portions of the shell segments for aligning the segments to provide a uniform protective covering for the casing.
  • Hand grenade according to claim 4 said shell segments being in abutting relation, and means disposed along abutting portions of the shell segments for aligning the segments to provide a uniform protective covering for the casing.
  • a hand grenade comprising:
  • (e) means biasing the cap, urging it off the casing and working axially of the casing
