This invention relates to improvements' in gelatin compositions, which may be used for lining receptacles, or for making capsules or containers or for similar uses.

5 An object of the invention is to provide a composition of organic matter which is relatively inexpensive, and which is comparative ly sott, flexible, and resistant to the corroding action of a variety of chemical compounds.

A further object is to provide a container otorganic matter which is sufficiently rigid at ordinary temperatures, to be safely handled, which is not brittle but which is de structible at higher temperatures, and which will not have a detrimental reaction upon, and accordingly will not spoil the contents of the container.

A further object is to provide a container of organic matter and a closure made of or coated with, the same material, which will prevent loss of its contents by leakage, etc.

A further `object is to provide a container for asphyxiating, or tear7 gas chemicals the loaded container to be used in a cartridge, and capable of being discharged when fired in a pistol, the container and contents being ejected by propellant powder in the cartridge, the material ot the container being ot com- 0 paratively soft gelatinous organic matter, and which is shredded or destroyed by the firing of the cartridge, the parts of the container being incapable of injuring anyone when the cartridge is red at close range and parts ot the container strike the person intended as the target.

A further object is to provide a container for chemicals to be used in cartridges and the like, the container being made of a corrosion resisting gelatinous substance that is comparatively soft and readily destroyed or shredded by the iring7 of the cartridge in a pistol.

A further object is to provide a composition of organic matter for containers to be used for asphyxiating gas chemicals, the composition being capable of resisting softening in humid atmospheres, and in hot weather, or when carried on the person.

Other objects of the invention will appear to those skilled in this art.

In the accompanying drawing- Fig. l represents a vertical section of a conventionaltype of container, with an inside i container.

Fig. 4 represents a vertical section of a conventional typeV of metal or fibrous container, coated inside and over the edgesof the opening with the gelatin corrosion resisting composition, and a perforated metal cover just above, the cover also being coated wit the composition;

Fig. 5 is a duplicate of Fig. 4 with the cover inserted, but not sealed;

Fig. 6 represents a vertical section of a metal container, coated inside with the gelatin corrosion resisting composition, and having a cover made of the composition, as in Figs. l and 2. rllhis type of cartridge may be used instead of that shown in Fig. 7.

Fig. 7 represents a vertical section of a cartridge containing a gelatin composition shell iilled with asphyxiating gas chemicals, and also a propellant powder charge, and a primer; and

Fig. 8 is a vertical `sect-ion of a gelatinous composition container, with an outside fitting cover, instead of an inside fitting cover.

Gelatinous capsules as heretofore made, have not been practicable for use as containers for asphyxiating gas chemicals; the containers were `too brittle for the service required, and had the property of softening in humid atmospheres and in hot weather, or in heated surroundings. A container to be practicable for this specialservice requires composition into the body of the chemicals.-

The corrosion resisting gelatin composition of this invention is preferably made as fol" lows Weigh out oneV hundred 'and` fifty" (150) grams of high grade gelatin, for example No. -X' sheet gelatin and placein -a glasser enameled vessel of aboutusix quarts capacity which hasbeen about three-quarters filled with Water ora water solvent at F.

(24 Let the sheet gelatin soakuntil it has taken up about one and one-half times its weight of water, about two hundred `and twenty-five (225) grams, (the time required is about 38 minutes). lf desired, the wat-er may contain some glycerine. Place the water soaked gelatin' in a suitable heater, for eX- ample an electrically heated glueepot, and turn on the current. When the gelatin has melted, and is of a uniform consistency, add about fifty (50) Vgrams of glycerine and stir thoroughly. The mixed mass should be maintained at about 17()o F. (76.7o (l), andy if it becomes too viscous, a small amount of water at 75 F. may be added, (cold water should not be added). Only one heating of the gelatin massshould be made. lf desired, suitable non-reacting colors may be dissolved in the melted mass, to produce capsules of different colors, in order that particular compositions may be placed in special .containers. Or the gelatin mass used for the caps may alone be colored.. .The caps or closures may if desired be made from an inferior grade of gelatin, such as a good grade of glue. rl `he gelatin mass should preferably be used in a room at from 7 5 to 80 F., with very little drafts and with a relative humidity of 40%-55%. For different substances, the quantity of glycerine added may vary from about nine percent to thirty-five percent, and of water, from fifty percent to about one hundred and fifty percent, of the weight of the gelatin used.

Afterthe mass has been prepared as above described, it is formed into capsules'l, and caps 2, Fig. 1, byprocesses well known in the art, the caps are perforated at 3, with a needle, which may be vheated if desired to avoid any cracking of the material. rIhe thickness of the walls on the drawing is eX- aggerate'd for purposes of illustration.

rlhe capsules and caps are now carefully cleaned of all foreign matter. The followingv method of cleaning has been found to be sets.

satisfactory. All surfaces which will be in contact with the Ychemicals to Vbe placed inthe containers are rubbed-with a cloth saturated with carbon tetrachloride, particular care is taken to clean both sides of the caps, and the inside of the capsules at least as far down as Y the caps extend.

rEhe, bodies of the capsules 1 are now placed pr'oXimately eighty percent (80%) of their 'upright in suitable trays, and filled to apcapacity with one ofthe asphyXiating-gas is' preferably justrbelow the flush edges of thecapsule. v.The filledcapsule with the cap lin 'place is nowsealed, Fig. 3, by applying a quantity of the melted gelatin mass 11, Yas `for example by pouring on top of, and around the' joint, at the edges of the capsule,V and over the perforation. Any bubbles arising should be wiped olf before the gelatin seal After the capsules have been sealed, they should be allowed tostand for about thirty minutes, after which they may,if desired, be painted on the outside at 12 with the same sealing material.

position.V Tliefcontaineris closed and sealed as described in connection with Fig. 3.

In Fig. 7, a chargedland sealed gelatinous capsule, 15, containing a charge of asphyX- iating gas chemicals 16, is placed in a cartridgeshell 17, the latter containing the propellant powder charge 18, and al usual primer 19. Vhen the cartridge is fired at aperson from a pistol, the gelatinous composition of the capsule 15 is either destroyed, or is shredded into small fragments which are soft, and will not injure a lperson should thek gelatinous fragments hit the victim in the face; the chemicals 16 will, however, be converted into a mass of gaseous asphyXiating fumes which are projected as a blast andV will overcome the victim, rendering his capture easy,

and without doing permanentV physical in- Jury In Fig. 8, the cap 20 fits tightly on the outside of the capsule 21, and after. vfilling, may

Vbe sealed by first applying a thick coat 'of the This outside paint-4 ing may extend from the top down to a point Y loo Y' molten gelatinous composition as a paint to the inside edge of the cap, and then quickly applying the cap; the molten gelatinous mass cementing the cap to the body of the capsule, after which the hole 22 in the top of the cap is also sealed as described above. v

The filled and sealed capsules, shown in Fig. 3, may be safely handled, will withstand a reasonable amount of rough treatment, and if desired, may be packed and shipped betore inserting in the cart-ridges as shown in Fig. 7.
