Definitions

  • the present specification relates to a patent of invention referring to improvements in smoke-producing shells for riot control, the evident purpose of which is to be used in a way similar to the conventional "smoke cans", and which can be hand-thrown or being shot by a firearm provided with a big mouth within which a shell can be introduced without the need of carrying out any modification on the shell itself, and irrespective of being introduced into the firearm big mouth in a position either upside up or upside down.
  • This invention applies to the industry for the manufacture of armaments and ancillary material.
  • the smoke-producing shells for riot control are manufactured at present of a metal material, and they are activated after being thrown by the corresponding firearms of the police officials, so that said smoke cans, when on the ground, release a gas provoking the dispersal of that group of persons to be purposely dispersed.
  • the French Patent of Invention No. 2,280,876 presents an ejecting fumigenic charge for shells, this invention referring to an object to be used in an exclusively military manner.
  • shells As known, the most asked for shells are those only and exclusively used for military purposes, and they are provided with a fumigenic or explosive charge, and their case containing a fumigenic and stable charge is manufactured of cast iron, a material which, as known by any expert in the art, is forbidden for civilian purposes.
  • this fumigenic or smoke-producing can is made starting from the incorporation into it of a powder charge, and, consequently, this charge is explosive and dangerous, its application being only and exclusively to military purposes.
  • the above-mentioned invention is configured as a monoblock case having, for being operated, a ring similar to those conventionally used in hand grenades.
  • This fumigenic grenade covered by the US patent of invention is to be only and exclusively used as a military arm, of special application to the infantry corps, and it is so configured that it allows to be used in marshy or flooded areas, owing to the fact that it has an external waterproof receiver, and relying on a firing gear which can be hand operated or being actuated by a gas direct impact or by inertial recoil forces.
  • the US Patent of Invention No. 388,942 shows a method of providing a watertight closing for fluids between a thin wall pipe and a piston, which refers to a missile for correcting military shots.
  • It is configured as a fumigenic cartridge for monitoring adapted shots so that when effecting its ejection, it acts as a propelling element of a smoke-producing or similar reagent, at a determined altitude on the air, which determines an easy monitoring of the shot, and, consequently, a correction of same in case of error.
  • the most suitable invention must not contain any type of explosive and, at the same time, can operate irrespective of the fact that the shell could be introduced into the big mouth in a position either upside up or upside down, not requiring any kind of modification to be stored.
  • the improvements in smoke-producing shells for riot control as proposed by the invention constitute, per se, an evident novelty in the industrial field into which they incorporate, since starting from same, it is possible to have an element capable of extensively surpass other similar elements existing in the market, allowing it to be thrown via any firearm fitted with an adequate big mouth, and being divided into three or more fragments on the aire, each of which will fall on the ground emitting a thick smoke cloud, and the exothermic chemical reaction simultaneously produced will consume each of the fragments, scarcely resting residues of same.
  • the improvements in smoke-producing shells for riot control as proposed by the invention are constituted starting from a body capable of being splitted in two or three minutes, without remaining any type of metallic rests, with a flameless combustion, not having any kind of edges, and consequently without any risk for the physical integrity of persons, and creating simultaneously three smoke sources enhancing its spreading power and tripling the neutralizable zone.
  • the invention is constituted starting from a light metallic casing adopting a cylindrical shape, and being fitted with a fastened cover, capable of being separated from the body if an inner pressure acts on same, a part carrying an inertia fuse and a capsule initiating the shell being screwed in the cover.
  • the casing of the three drilled cylinders is configured starting from a metal having a low melting point, and a separator has been provided between the cylinder and the light metallic cover, the function of this separator is to fix the cylinders within the casing and consequently to create a low pressure chamber capable of absorbing the gases originated by the combustion of the initiating strip, until the strip fulfills its specificmputation of initiation of the mixture of the three cylinders.
  • the rigid initiating strip is located, which is covered with a pyrotechnic mixture having an easy initiation and being capable of creating, in its combustion, the necessary thermic energy to initiate the fumigenic or tear-producing mixture of the three cylinders.
  • the object of the invention is complemented with a layer of plastic material, which is screwed in the part carrying the fuse, and adjusted, at its lower side, to the shell, the specific purpose of which is to protect the shell.
  • the lower side of the shell is fitted with a rubber disc, the function of which is to protect the shell in transit and when it is shot, forming an - assembly having a metal disc avoiding the shell to be perforated by the fire dart and the gases emitted by the firearm with which it is shot.
  • This two disc assembly is joined to the lower side of the shell by means of a plastic part into which the metal casing is tightly inserted.
  • the only figure shows a view of the object of the invention related to improvements in smoke-producing shells for riot control, seen in a sectional view.
  • the cover (2) is screwed in a part (3) carrying an inertia fuse, and, also, a capsule initiating (4) the shell.
  • the cylinder (5) casing is made of a low melting point metal, and a separator (8) is located between the cylinders (5) and the casing cover (2); this separator (8) secures the cylinders within the light metallic casing (1), and, consequently, creates a low pressure chamber (15) capable of absorbing the gases emitted by the combustion of the initiating strip (6), until this latter carries out it's task of initiating the mixture of the three cylinders (5)
  • the rigid initiating strip (6) is located, which is covered of a pyrotechnic mixture, of easy initiation, and being capable of creating, in its combustion, the necessary thermic energy to initiate the fumigenic or tear-producing mixture of the three cylinders.
  • the shell is completed with a plastic cover (7), screwed in the part carrying the fuse (3); and adjusted, at its lower side, to the shell body, the function of which is exclusively to protect the fuse (3).
  • the shell is fitted with a rubber disc (9), which protects it in transit when it is shot.
  • a metal disc (10) avoiding the shell to be perforated by the fire dart and the gases emitted by the firearm with which the shell is shot.
  • the two disc assembly that is to say, the rubber disc (9) and the metal disc (10), is joined to the lower side of the shell by means of a plastic part (11) in which the metallic casing is - tightly inserted (1).
  • this initiating strip (6) is not instantaneous owing to requirements with regard to thermic characteristics and the absence of a mechanical wave demanded in it, to initiate the mixture of the cylinders (5) contained by the shell.
  • Said cylinders (5) fall on the ground already initiated, emitting a fire dart and a thick smoke cloud via one of the orifices drilled at their bases, and when the reaction is progressed and the smoke emission is finished, the cylinder has disappeared leaving only a small residue on the place where it fell.
