Definitions

  • the grenade according to the present invention, satisfies these main requirements in conditions of extreme simplicity of working and low cost of manufacture.
  • the grenade is provided with a striker such as indispensable for operating the detonating device, which striker may be removed from or fitted to the grenade in an instant.
  • a means for pulling consisting of a tape that, only on'reaching its full stretch, releases the safety catch of'the detonating device, and does so not wholly but in part, leaving it ready to release itself and cause the explosion when the grenade strikes the target;
  • the third condition is fulfilled by the fact that afterthe safety-catch has been partly released, the detonating device is left in such a position as to convert the grenade into a percussion bomb.
  • the fourth condition is satisfied in as much as the position of the detonating device in an unexploded grenade is ascertainable by mere visual examination.
  • the bomber retains a part in the shape of a tape, which causes the safetycatch' of the grenade to fall; according to the other, this releasing part separates from the grenade of itself during the flight of the latter through the air.
  • Fig. 1 is a section through AB of Fig. 3.
  • Figs. 2 and 2 are details, in section, of the form of construction shown in Fig. 1.
  • Fig. 3 is a general view of the grenade seen from the side on which the firing device lies, which latter is shown in front View.
  • Fig. 4 shows the firing device in a variant form of construction from that shown in the three last figures.
  • the grenade forming the subject of the invention is composed of a spherical body 20, inside which are arranged the explosive charge and grape-shot as well as the detonating device and the mechanism actuating the same.
  • the detonating device consists of a cartridge 21 arranged inside a tube 22 and provided with a detonator 23 suitable for being struck by a striker 24 provided at the opposite end of the tube 22.
  • This striker consists of a member that is fitted to the body of the grenade by a screwor bayonet-joint enabling it to be withdrawn or fitted instantly; for example, at the moment of use, and of being removed during transport, thus constituting a first and absolutely efiective safeguard.
  • the cartridge lies in a position of rest, against the pressure of a spring 25, which projects it against the striker, thus causing the explosion; and is held in that position by the firing mechanism which, until released, prevents the cartridge from being displaced.
  • the spherical cap 1 has a hole in the centre to take screw 2, the end of which penetrates into the firing lever 3. This lever, close to the end in which is inserted the screw 2, is bored to take the pin 4 which is pressed downward by the spring 5; the upper end of pin 4 penetrates into the opening 6 bored in the part 7, whilst the lower end 8 rests on a box 9 containing the tape 10 that operates the mechanism. This tape is folded and not wound.
  • the tape 10 (Figs.
  • the tape 2 and 2* either passes split in two through two holes provided in the cap 1 and forms a knot and a ring for the bomber to use if required for throwing the grenade whilst retaining the tape and the cap inhis hand; or else the tape may be arranged, as shown the drawing, to pass through the cap and be fastened when the grenade is to be used; at very short distances, thebomber may draw out the tape until a mark appears on it very near its inner endan arrangement that may be of use in the case of hand-to-hahd or close fighting.
  • the screw 2 holds the cap 1 fixed against the outersurface of the grenade. It also holds the firing lever B and the pin 4 in a fixed position and absolutely prevents the'accidental firing of the grenade, this being one of the characteristics of the invention.
  • a leather washer 11 is provided, forming a close joint, and preventing water or other fiuids from penetrating into the grenade.
  • the screw 2 is unscrewed and the grenade is either thrown in the manner last described, so that the cap exerts a pull upon the tape 10, or the cap and the tape are retained in the hand by means of the loop forming the end of thetape, as shown in Figure 2.
  • the tape unfolds from inside the box 9 and, on becoming tensioned, it exerts a pull on this box, to the bottom of which it is knotted at 12, with the result that the box is pulled out from inside the grenade.
  • it is given a semicircular shape.
  • box 9 is arranged in the body of the grenade and at the top has an opening underneath the end 8 of pin 4. Over that opening is fitted a plate 17 having a groove 18 through which passes the tape, the inner end of which is secured to the part of the plate lying between its edge and the said groove. It will be readily understood that plate 17 stops any downward movement of the pin 4 under the action of spring 5 as long asth'e tape is not fully unfolded, but that the tape, on becoming fully unfolded, exerts a pull on the plate 17, displacing it and allowing the pin 4 to drop under the action of spring 5.
  • the ring for sustaining the grenade is replaced by a plug 13 the inner bore of which is square down to certain depth, to enable the plug to be screwed into the grenade with a key, after which the bore is round, as shown at 14; the object of this shape of plug is the following.
  • On two faces of the square-bored part are provided grooves 15, and at the bottom of the said part a notch 16.
  • the bomber is provided with a belt studded throughout its length with stout pegs (which are not shown) which fit into the bore of the plug in the grenade so that two knobs provided on each peg enter into the grooves 15; thus a mere turn of the grenade is sufficient to snap it on to the peg, the knobs of which fit into the lower notch 16.
  • This simple bayonet-socket enables a large number of grenades to be rapidly carried and also rapidly and easily handled by each bomber.
  • a grenade without changing the firing mechanism, can be cylindrical or of any other shape.
  • a hand grenade comprising a body to contain an explosive material, a cartridge movable in the body and having a detonator, means to guide the cartridge, a spring to move the cartridge, a striker engageable by the detonator of the cartridge when the latter is moved by the spring, a firing lever in the 'body, a removable cap on one side of the body, and a screw'carried by the cap securing the same to the body and engageable with the lever to 'hold the latter in the required .position to prevent movement of the cartridge while the cap is in place, and "to release the lever when the cap is removed.
  • Ahand grenade comprising a body to contain an explosive material, a cartridge movable in the body and having a detonator, means to guide the cartridge, a spring to move the car-; tridge, a striker engageable by the detonator of the cartridge when the latter is moved by the spring, a firing lever in the body, a removable 1 cap on one side of the body, and a screw carried by the cap securing the same to the body and engageable with the lever to hold the latter 'in the required position to prevent movement of the cartridge while the cap is in place, and to release the lever when the cap is removed, additional means to hold the lever 'in cartridge detaining position and releasing means for the additional lever holding means and including .a tape arranged in the body and connected to the cap and active, after the grenade is thrown, to release the additional-holding means.
