Definitions
- This invention relates to a new priming compound for use with explosive cartridges and the like.
- This new compound has been tested in various cartridges, with a variety of makes of smokeless powder, and has been found to give a higher and less variable velocity to the projectile than the priming compounds hitherto employed.

Description
UNITED STATES PATENT OFFICE.
MAURICE R. sworn, or ALTON, ILLINOIS.
1,073,941. No Drawing.
To all whom it may concern:
Be it known that I, MAURICE R. Sworn, a citizen of the United States, and a resident of Alton, in the county of Madison and State of Illinois, have invented a new and Improved Priming Composition and Method of Preparing the Same, of which the following is a full, clear, and exact description.
This invention relates to a new priming compound for use with explosive cartridges and the like. This new compound has been tested in various cartridges, with a variety of makes of smokeless powder, and has been found to give a higher and less variable velocity to the projectile than the priming compounds hitherto employed. It possesses the further advantage over the latter that there is practically no erosion of the gun barrel when using my primer made as hereinafter described. It has proved sufiiciently sensitive to explode quickly in weak spring guns, and is less dangerous to handle than mercury fulminate. The ignition is quick and the flame hot and penetrating.
The following is a description of the process by which I prepare the new priming compound: I first prepare a gelatinous mass compounded of gun cotton or pyroxylin and amorphous phosphorus, in the following proportions: Gun cotton parts; amorphous phosphorus 20 parts. As solvent in this operation I may use either acetone, or, in case so-called soluble cotton is employed, I may use a mixture of ether and alcohol in the proportion of two parts to one part. After this mass has become thoroughly dry, I pulverize it and mix it with the following Specification of Letters Patent.
Application filed April 23, 1913. Serial No. 763,071.
Patented Sept. 23, 191E ingredients in the proportions stated: Gu cotton-phosphorus compound 25 parts, pt tassium chlorate 87.5 parts, antimony sulfi 37 .5 parts.
The resulting body is a priming com pound possessing the advantages hereinba fore pointed out.
Vhile the proportions indicated abov have been found the most suitable for ger eral purposes, I do not limit myself to thee proportions, but may employ the ingredf ents stated in quantities varying within ce1 tain limits from those given.
Having thus described my invention, who I claim as new and desire to secure by Let ters Patent is:
1. A process of producing a priming corr position, which consists in preparing a mix ture of gun cotton and amorphous phos phorus, allowing the said mass to dry, pow dering the same, and mixing therewith p( tassium chlorate and antimony sulfid.
2. A priming composition containing gu cotton and amorphous phosphorus, potas sium chlorate and antimony sulfid.
3. A priming composition containing th following ingredients in substantially th proportions stated; Gun cotton 20 parts amorphous p horus 5 parts; potassiui we 37.5 par s; antimony sulfid 37.
parts.
In testimony whereof I have signed m name to this specification in the presence c two subscribing witnesses.
. MAURICE R. SVVOPE.
