EQBEET B. FUL'I'GN, INDIAN HEAD,
EYRGTECEIIC COMEOSITIOQ'.
Specification of Letters Patent. Patented Dec. 313, 1921,
Ho Drawing. Application filed April 16, 1921. Serial No. 461,955.-
To all whom z't may comer /z: Iron powder -20 parts. Be it known that 1, ROBERT R. FULTON, (J ri xid 2-15 a citizen of the United States, residing at Indian Head, Maryland, have invented new and useful Improvements in Pyrotechnic Composition, of which the following is a specification.
This invention relates to pyrotechnic compositions particularly adapted to be used in igniting pipe or other pyrotechnic compositions which require a high temperature for ignition.
()ne of the objects of the present invention is the production of a non-gaseous ignition powder to be used in connection with, and as an ignition or starting powder for, pyrotechnic compositions, and the like which are themselves difiicult to ignite.
A further object of the invention is to provide a pyrotchnic mixture which Will ignite from the spit of a miners or safety fuse, or upon application of red heat to a very small area of the mixture,-ma king it unnecessary to raise the temperature of the entire mass to the point of ignition, before ignition takes place a mixture which is safe to handle and manipulate; which is practically non-gaseous; which burns quietly, giving a bright yellow heat, and-a very hot slag; and which will not deteriorate when v stored for long periods of time.
Other objects will be in part obvious and in part hereinafter pointed out.
The present invention preferably consists of a mixture of iron powder, powdered cupric oxid, and powdered magnesium metal.
In preparing the composition, I prefer to use the ingredients in about the following proportions, viz
Ironpowder 15 'Gupric oxid 5 Magnesium metal -3 Good results may be obtained, however, when the ingredients are varied within the following limits parts. 7
..Magnesium metal 0.5-3.5
wide limits by varying the percentage of magnesium and iron owder. The amount of heat liberated can e controlled by varying the amount of cupric oxid. The composition should be stored in dry, air-tight containers of glass or tin.
My composition ignites from the spit of a fuse, or the touch of a red hot wire; burns quietly with only a very slight evolution of gas, produc' a ve hi 11 tom and a hot sl zi It p d s sesse as in a 'gh de-' gree all the esired properties .of a pyrotechnic mixture to be used as an ignition powder for other pyrotechnic compositions and the like which require a high temperature for i nition.
What i claim is:
'1. A pyrotechnic composition of the character herein described containing iron powder, cupric oxid and magnesium metal.
2. A pyrotechnic composition of the character herein described containing iron powder, cupric oxidand magnesium metal, all in powdered form.
' 3. A pyrotechnic composition of the character set forth comprisin substantially fifteen parts of iron powder, five parts of cupric oxi'd and three parts of magnesium metal.
Signed at Indian Head, Maryland, this 25th day of March, 1921.
rature,
L ROBERTA R. FULTON.
