Definitions

  • a spraying canister for simulating the discharge of poison gases over terrain having a container to hold a mock gas with a detonator and a time-delay mechanism and a propellent and explosive charge to burst the container and spray out the contents thereof.
  • the invention relates to a spraying canister for simulating the discharge of poison gases over terrain, consisting of a container holding a training (or mock poison) gas, a detonator and time delay mechanism inserted into the lid of the container, a propellent charge for ejecting the spraying canister from a discharge cup, and an explosive chare for bursting the container and spraying out the contents.
  • Spraying canisters of this type are known. They are used, on the one hand, to simulate grenades, rockets and bombs filled with poison gas and, on the other hand, the gaseous medium used, which generally consists of a neutral fluid, has to be detected in the countryside which is achieved by contacting it with a dispersed powder to colour it and make it very clearly visible.
  • Spraying canisters of this kind essentially consist of a 3 training gas container made of sheet steel (fitted with a detonator, propellent charge and explosive charge),
  • the explosive charge only igniting and destroying the container, thus spraying out the contents, when the container has reached a given height above the ground.
  • the spraying canister container Because it is made of sheet steel the spraying canister container has sufiicient strength and stability on firing that there is no danger of the container exploding prematurely.
  • the object of the invention is to reduce or eliminate these disadvantages and drawbacks, and this is achieved by making the spraying canister container of a synthetic material which disintegrates into small parts which are not dangerous, the required stability of the canister during firing being provided by ribs thereon.
  • the discharging cup 1 is of a simple, cylindrical sheet steel holder, which is preferably, as shown, buried up to the upper rim in the earth.
  • the spraying canister complete with all detonating, propellent and explosive components is inserted into this holder.
  • the spraying canister essentially consists of a thinwalled container 2 having a one-piece, cylindrical shell 2a with a cap 2b fitted to it, and an insertable bottom 3, all made of a synthetic material capable, on explosion of the canister, of disintegration into small, harmless parts.
  • the shell 2a In the upper and lower regions of the shell 2a there are circumferential, riged reinforcing ribs 4 projecting radially outwards which not only increase the stability of the container, whilst keeping the same wall thickness, but also above all act as guide devices in the discharging cup and provide a seal between the container 2 and discharging cup 1.
  • the cap 2b formed integrally with the shell 2a has a diameter which is sufficiently larger than the reinforcing ribs 4 of the shell 2a, for the shoulder 5 connecting the cap 2b to the shell 2a to act as support resting with its lower edge on the rim of the discharging cup 1.
  • This shoulder 5 of the cap engaging over the rim of the discharging cup 1 has the particular advantage over the previous design thatso long as the spraying canister is held in the discharging cup-neither dirt nor rain can penetrate into the discharging cup 1.
  • the dimensions of the container from the shoulder 5 to the bottom edge of the base 3 can be so chosen in relation to the height of the discharging cup that the base of the container does not extend to the bottom of the discharging cup, so that the spraying canister 2 is suspended in the discharging cup 1 from its shoulder 5.
  • the base 3 is arranged to project a substantial amount inside of the container 2. Thin, but deep, radial ribs 3a give the base exceptional stability.
  • the base 3 has a doubled-back rim formed by edges 6 and 7 which fit tightly round the lower end of the shell 2a, the outer edge 7 having an inwardly directed hook 8 engaging in a recess 9 in the outer surface of the shell 2a.
  • the hooked edge expands slightly and snaps into the recess 9. This quick and eflicient fixing of the base 3 can be improved still further if both edges 6 and 7 are fixed to the shell 2a by a suitable adhesive.
  • the outer edge 7 corresponds in diameter to the reinforcing ribs 4 and therefore has the important function of being the guide and seal element closest to the propellent charge located in the base 3.
  • the base 3 is fitted with various attachments, e.g. with an attachment 10 for holding a propellent charge 10a, an attachment 11 for connecting to a detonator and delay tube 11a containing the detonating and delay system 11b and an attachment 12 for holding a capsule 12a containing an explosive charge 12b.
  • the detonating and delay system tube 11a projects upwards beyond the cap 2b and is fixed by a nut 13 which in turn mounts a detonator, e.g. a friction igniter 14 operated by a pull wire 14a.
  • the cap 2b also has a filling connection 15 closed by a cap 16.
  • a lid 10b which is about level with the lower edge of the container.
  • a threaded plug 17 having a central bore 17b which contains a delay mechanism 17a.
  • the spraying canister 2 as shown in the drawing is inserted into the discharging cup 1 ready for firing.
  • the ignition system of the friction igniter 14 reacts and transmits an ignition spark to the time fuse 11b.
  • the time of combustion of this fuse is such that troops can leave the zone of activity of the spraying canister without hurrying.
  • the time fuse 11b has burnt down to the base 3, it ignites the propellent charge 10a so that a high gas pressure builds up beneath the base 3 which projects and accelerates the spraying canister to a height of about 30 metres, depending on the position of the buried discharging cup.
  • the propellent charge 10a has also ignited the time fuse 17a in the central bore 17b.
  • the combustion time for the fuse 17a corresponds approximately to the flight duration of the spraying canister so that at the moment at which the canister reaches its maximum height, the fuse 17a detonates the explosive charge 12b which in turn bursts the container 2 and sprays its fluid contents over a wide area.
  • the container disintegrates into small parts which are not dangerous because of their small weight.
  • the gaseous contents consist of a neutral fluid with the special property that its presence can be detected in the countryside by colouring produced by a dispersed powder.
  • the flight duration, height of trajectory, time of explosion and scattering area diameter can be changed by altering the characteristics of the ignition time fuses 11b and 17a and the propellent and explosive charges 10a and 12b.
