Application June 2, 195o, serial No. 165,723 vi-claims. (o1. v1ct- 38) This invention relates to new and useful vimprovements in ammunition. 1
An object of this invention is to provide an improved round of ammunitionwhich includes a normal casing with a projectile disposed therein, however the projectile is providedv with a rear end portion which accommodates a sleeve memthe charge being separated from the filler in the projectile by means of a heat resisting seal and being separated from the normal "charge by means of an inflammable seal which is arranged in an orifice formed at the rear end of the sleeve member.
Other objects and features of importance will become apparent in following the description of the illustrated form of the invention.
In the drawings:
Figure 1 is an elevational view of the device,`
portions being broken away in section to illustrate detail of constructiomand,
Figurez is an exploded perspective view of the projectile,` and other elements in the makeup thereof.
In carrying out'this invention there is provided a casing I9 with the neck l2 at the forward end thereof, the casing having a chargey of explosives i4 therein, the explosives being conventional in nature.
The projectile or jacket I6, disposed in the neck I2, is provided with a filler I8 of Alead or` the like, in the front end thereof. A sleeve member 29 is disposed in the rear end 22 of the projectile and the heat resisting alloysmetal seal 24 is disposed of the forward open end thereof to separate the secondary charge 26 of explosive material from the filler I8.
The rear end of the sleeve member 29 is crimped as at 28 to form an orice 39. The crimp 2S is so arranged as to form a Venturi shaped orifice and there is a seal 32 disposed therein.
The seal is made of a flammable material, as paper, cardboard or certain flammable plastics which may be chosen from known publications tabulating the properties thereof, as the publication Modern Plastics. The seal 32 forms a small housing to accommodate a part of the charge 26 and has a flared forward end 34 which Y is disposed in the orifice 39.
Accordingly. the outside surface of the anged end 34 bears against the inside surface of the crimped-material of the sleeve member thereby holding the seal assembled. l
The rear extremity 39 of is fiared inwardly in order to seat in the crimp 28 to thereby hold the sleeve member 20 assembled in the rear end portion 22.
In operation the ammunition is iired as is normal and expected. that is, by means of a gun of one type or another. The first occurrence the end portion 22 is the burning of the charge i4 to send the projectile flammable seal also ignites or transmits pressure to the vsecondary chargev 29 so that theV charge 26 may burn sequentialy to the firing of the main charge I4.
After the secondary charge 25 fires, the gases resulting from its combustion will be expanded ,4 through the orifice causing the .projectile IB leading end of said jacket, a hollow extension forming therear part of thev jacket disposed in i the open end of said shell casing, a sleeve member disposed in said extension, a secondary charge in said sleeve member and an inflammable seal at the rear end of said sleeve member separating said primary charge from said secondary charge, a crimp in the rear end of said sleeve member forming an orifice, said seal being hollow and receiving a part of said secondary charge, and said seal having a flared front end insaid orice and binding against said crimp to hold said seal in said extension.
2. In a projectile having' a rear hollow open end, a sleeve member received in the rear end of said projectile, a charge in said sleeve member, and an inflammable seal carried by the sleeve member at the rear end of the projectile and having a hollow -rear portion extending rearwardly from the rear end of said sleeve member and the rear end of said projectile and receiving a portion of said charge.
. 3. The combination of claim 2 wherein said sealv includes an outwardly flared forward end `positioned in the rear end of said sleeve member, 'and a crimp in the rear end of said sleeve member engaging said flared forward end and retaining the seal relative to the sleeve member.
4. The combination of claim 3 wherein said rear end of said projectile includes an internal flange at its rear extremity entering said crimp and retaining the sleeve member in said hollow rear end of said projectile.
