Definitions

  • This invention relates to a projectile the func-- tioning of which does not give rise to the production, however slight,'of any splinters, or even to the expulsion externally of plugs or other ob- 5 turating devices.
  • the projectile of the present invention is therefore particularly adapted for use as a smoke-shell or signalling shell for firing practice. It affords, furthermore, the advantage of being recoverable with a view to subsequent use.
  • the projectile of the present invention is of the type comprising an interior cavity provided with an emission orifice closed by a plug or equivalent device adapted to be forced aside under the effeet of pressure produced inside said cavity by an appropriate charge, and is characterized by the feature that said plug is disposed in such a way as to remain in the projectile after its displacement.
  • Fig. 1 is a cross-section of the projectile; while Fig. 2 shows the valve in the open position.
  • the body I of the projectile is provided, preferably towards its rear extremity, with a perforation 2 (Fig. 2) closed by a valve 3 held in the closed position by crimping,
  • a retention device formed in the present example by a projection 3a of the body I, makes 5 it impossible for the valve to be forced inside the body, particularly under the action of the propulsion when the shot is fired.
  • the tightness of the joint between the valve and the body is obtained preferably with the aid 50 of thick copal varnish or an equivalent product.
  • a cavity 4 which is itself in communication with the exterior through one or more perforations 5, of variable inclination, made in the base of the shell.
  • a channel 9 is provided in the smoke-producing composition (for example hexachloroethane and calcium silicide, if desired with the addition of colouring matter) in which is disposed the ignition composition (hexachloroethane and alum minium, for example).
  • the channel 9 connects the valve 3 to a detonator H), which preferably has a fulminate base.
  • ballast the latter-consisting of kieselguhr, pitch or any 15 other appropriate material-is preferably disposed around the internal periphery of the shell at its region of maximum diameter.
  • the body I has at the front a tight cover I! into which is screwed the fuse I3. For storage in storehouses the fuse may be replaced by a tight plug.
  • the ignition composition in direct contact with the charge 8 it could also be placed in a combustible tube (of cardboard, celluloid, or the like) or else in a non-combustible perforated tube.
  • Said composition could also be disposed in a channel or in a tube situated eccentrically in the projectile: this channel could, moreover, be of a shape other than straight; such as helicoid, zig-zag, and so on.
  • a plurality of channels could be provided.
  • the shell If it is desired to use the shell as a tracer projectile, it is sufiicient to effect the ignition of the charge at the desired moment by means of an appropriate fuse.
  • the present invention is applicable to projectiles of any kind fired from smooth or rifled guns, to grenades of all kinds, to aircraft bombs, and so on.
  • a non-explosive projectile having a hollow body formed with at least one emission orifice, a stabilizing fin-carrier tail fixed in a hole provided in the base of the projectile in alignment with said emission orifice, a plug for hermetically closing said orifice, an expansible charge inside said hollow body, and means for expanding said charge when the projectile attains its target, the said plug being adapted to yield under the effect of pressure produced inside the said hollow body by the expansion of said charge and to move against said tail and abut thereon.
  • a non-explosive projectile having a hollow body formed with at least one emission orifice, a stabilizing fin-carrier tail fixed in a hole provided in the base of the projectile in alignment with said emission orifice, a plug for hermetically closing said orifice, an expansible charge inside said hollow body, and means for expanding said charge when the projectile attains its target, said plug being adapted to yield under the effect of pressure produced inside the said hollow body by the expansion of said charge and to move into opening position against said tail, and said body having at least one outlet channel in communication with said hole between the closing and opening positions of said plug 3.
  • a non-explosive projectile having a hollow body formed with at least one emission orifice, obturating means for hermetically closing said orifice, an expansible charge inside 'said hollow body.
  • a fuse to ignite said charge when the projectile attains its target
  • an ignition composition to transmit the defiagration from the fuse to said charge, said composition being provided in a channel connecting said fuse to said emission orifice
  • said obturating means being adapted to yield under the effect oi pressure produced inside the said hollow body by the expansion of said charge, and means to retain said obturating means entirely within said body after the yielding movement.
  • a non-explosive projectile having a hollow I body formed with a cavity of approximately ovoid form and with at least one emission orifice, obturating means for hermetically closing said orifice, an expansible charge inside said cavity, a charge of ballast surrounding said expansible charge in the region of greatest diameter of the cavity, means for expanding said expansible charge when the projectile attains its target, the said obturating means being adapted to yield under the eflect ofpressure produced inside the said cavity by the expansion of, the expansible charge, and means to retain said obturating means within said body after the yielding movement.
  • a non-explosive projectile having a body cavity with an emission orifice at its tail end, an expansible charge in the cavity and means for efl'ecting expansion of the same, said orifice comprising a passage having a shoulder adjacent the cavity, plug means normally seated against the shoulder and eiiective for hermetically closing said orifice and movable by the expanding charge away from said shoulder into a non-closing position, a stabilizing tail having a portion removably received in said passage to obstruct the same against escape of the plug means when the latter moves to non-closing position, said passage also including an escape channel which is closed oil?
