Description

Patented Oct. 9, 1934 UNETE PATENT OFFECE George U. Grafi, Washington, D. C.
No Drawing. Application January 18, 1933, Serial No. 652,431
1 Claim.
(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) This invention relates to a pyrotechnic material for producing orange smoke and has for its object to provide a composition that will evolve an abundance of deeply colored smoke of i the color specified.
With the above and other objects in view, this invention consists in the construction, combination and arrangement of parts as will be described more fully hereinafter.
A composition well adapted to produce orange smoke is lead peroxide parts, potassium bichromate 35 parts, and magnesium 15 parts. The potassium bichroinate furnishes part of the oxygen necessary to burn the magnesium and stop i reduction of the lead peroxide at the red lead stage to impart the necessary redness and give a resultant orange smoke.
The substance specified gives off puiis of orange smoke that are particularly adapted for use in daylight fireworks and various daylight signaling devices, though the application of this invention is not limited to the purposes specified.
It is to be understood that the proportions specified for the several ingredients represent the preferred percentages for each combination but that strict adherence thereto is not essential, as good results are obtained even when they are varied within considerable limits.
The herein described invention may be manut5 factured and used by or for the Government of the United States for governmental purposes without the payment of any royalty thereon.
I claim:
A pyrotechnic composition for producing orange smoke, comprising lead peroxide 50 parts, potassium bichromate 35 parts, and magnesium 15 parts.
