can'rnmen run rmnms Application filed April 23, 1931. Serial No. 582,864.

It has been ascertained through test that this chemical or any of its substitutes willdecompose or deteriorate so as to be useless within a few months time unless the cartridge shell or container is lined with glass, and it is an object of this invention to provide a capsule or envelope for the chemical which will be instantly destroyed as an entirety by the explosion of the shell in the gun, thereby avoiding the decomposition or deterioration of the chemical within the shell of the cartridge in any such time or to materially The invention consists in the novel con-' struction and combinations of parts as set forth in the appended claim.

In the accompanying drawing illustrating the invention:

Figure 1 is a central longitudinal section of the invention.

Figure 2 shows in perspective detail view tgellchemical container and the cartridge s e Figure 3 is a cross section of the chemical container.

Figure 4 is a detail fragmentary view of one end of the chemical container 1n section.

In this drawing the numeral 1 designates an ordinary cartridge shell such as may be bought in the open market, and having the usual percussion cap 2.

The tear gas chemical 3 before being placed in the cartridge shell is placed within a container, envelop or ca sule 4 made of any suitable thin material of equal thinness throughout which will be atomized disintegrated or burned up at the moment 0 I discharge of the small amount of black or smokeless powder 5 placed in the shell in rear of the chemical envelop as a propellant and to generate sufiicient heat in its explosion to immediately dedisc arge ofthe chemical from the cartridge,

the latter being intended for use in the tear gas gun of the co-pending application of applicant. At the time of such discharge the chemical is of course dispersed forwardly over a wide area and particularl towards the object at which the gun is aime The chemical is placed in the envelop preferably by machinery or afilling device of some kind before the envelop is placed in the primed shell, thereby avoiding hazard to the workman filling the envelops. V

The envelo being sealed air tight, prevents the chemical rom coming in contact with the metal of the shell, which is one of the usual causes of deterioration. j

Among the materials of which the envelop may be made are cellulose, or rubber composition, impregnated paper, etc.

The sealing of the chemical within the container or envelop 4 may be done in any suitable manner, such for lnstance as by the use of a top disk 6 of the same material as that of the container, sealed around the mar with cellulose acetate, parafiine or seahng wax.

I claim In a tear gas cartridge, having a primed shell, a propellant and heat eneratin filling for the inner end portion 0 said she and a. substantially complete filling for the entire outer end portion of said shell consisting of a tear gas chemical and an envelope entirely surrounding said chemical and composed of such readily combustible material of such extreme thinness throughout that it will be immediately consumed as an entirety at the moment of the explosion of the shell in the whereof I aflix my signature.

stroy the chemical envelop atthe time of the I
