Description
the particles to LEONARD WALDO,
OF PLAINFIELD, NEW JERSEY, 'ASSIGNOR TO AMERICAN MAG- NESIUM CORPORATION, A CORPORATION on NEW YORK.
FLASH OR FLARE PRODUCT.
No Drawing.
To all whom it may concern:
Be it known that I, LEONARD VALDO, a citizen of the United States, and resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Fiash or Flare Products, of which the following is a speci fication.
This invention relates to flash or flare products for signaling and other purposes, having reference more especially to flash or flare powders composed of magnesium, or other combustible metal, either with or without the addition of an oxygen yielding material.
It has been proposedto mix or combine the powder with fibrous material, such as asbestos, or corded unspun wool impregnated with vegetable oil, for the purpose of separating the metallic particles and thus enabling the morethorough contact of oxygen therewith in order to promote combustion. Such admixture of the powder with fibrous material serves to separate the particles to some extent, but there is absent that thorough interstitial formation requisite and necessary to insure the efiicient exposure of the chemical action of the oxygen. Moreover the intermixed fibersdebase the powder in such a manner as to retard its combustion, and reduce the brilliancy and force of the flash or flare.
The object of my invention is to accomplish the requisite lnterstitial formation of agglomerated ignitible metallic particles without the addition of fibrous or other foreign substance; and to that end I reduce magnesium, or other combustible metal, to
thin shaVing-like particles of irregular curvature which are promiscuously intermixed either with or without the addition of a suit- I able oxidizing agent, as Wlll be hereinafter described and claimed.
In accordance with the principle of my invention I reduce magnesium, or similar combustible metal, to shaving-like or filamentous form and promiscuously intermix the attenuated particles, which are of irregular curvature, so as to produce therein a multiplicity of interstices that permit and insure the free distribution of oxygen throughout and in intimate association with the individualparticles. The thinness of these metallic particles, when they are heated in the presence of the freely distributed oxygen, promotes their quick ignition and Specification of Letters Patent.

Application fied December 22, 1916. Serial No. 138,361.
combustion whether the oxygen be furnished from the air or by any well-known oxidizing salt ordinarily used as an ingredient of flash powder or torch mixtures; such, for example, as peroxid of manganese, or perchlorate or chlorate of potassium.
An excellent flash or flare product embodying my invention consists of equal parts of filamentous magnesium and peroxid. of
manganese.
In the production of the shaving-like or filamentous particles they are severally sensibly curved thereby insuring adequate gaps or spaces between the opposed surfaces of the agglomerated material, and the individual particles are preferably not greater than 1/50 of an inch in thickness, nor 1/30 of an inch in width, nor 1/3 of an inch in length. The characteristic material being readily ignitible and combustible is pe culiarly suitable for use as or in the preparation of a flash or flare product as above mentioned,
In my experiments that the shaving-like or filamentous material above described can be economically produced by lightly pressing-a body of magneslum, or similar combustible metal, against a carborundum wEheel running at high speed,
approximately 4:,200 feet per minute; the periphery of the wheel rapidly tearing the attenuated particles from the impinging surface of the metal.
I claim 1. A pyrotechnic composition comprising, as an essential component thereof, particles of crooked, shaving-like structure composed of a light, readily combustible and easily ignitible metal. I
2. Apyrotechnic composition comprising, as an essential component thereof, particles of crooked, shaving-like structure composed of a light, readily combustible and easily ignitible metal, such particles having a maximum size not materially greater than 1/50 inch in thickness, 1/30 inch in width, and 1/3 inch in length.
4c. A pyrotechnic composition comprising,
as an essential component thereof, particles of crooked, shaving-like structure of metallic magnesium, such particles having a maxiof crooked, shaving-like structure of metallic magnesium, such particles having a maximum size not materially greater than 1/50 inch in thickness, 1/30 inch in Width, and
1/3 inch in length, together with a solid oxidizing agent,
Signed at New York, in the county and State of New York, this 21st day of Decemher, A. D'. 1916.
