IGNITION PELLET.

Application led February 19, 1923. Serial No. 620,064.

To all whom t may concern: i s i Beit known that lt, YUYEMON KEDA, a

.subject of the Emperor of Japan, residing at Gardena, in the county of Los Angeles and State of California, have invented a new and useful Ignition Pellet, of which the following is a specification.

This. invention relates to ignition pellets, and has for itsl object the provision of an improved means for igniting combustible materials and for producing fire; the pellets being intended as a substitute for matches,

\ and consisting of a globular pellet of combustible material, dipped in and coatedw'ith pyrophoric ma-teriahand having an outer coating of an ignitible material. I

Heretofore, matches have consisted Aof a wooden splint, having one; end .coated with Some ignitible composition, suchA matches being held by the hand of the operator during ignition and combustion of the match. To obtain a vsubstitute which may be contained in a more limited space, or which may include a much larger number in a limited space, Ivhave designed an ignition pellet, comprising a globular combustible material coated with pyroplioric and ignitible materia-ls, and having a combustible capacity equivalent-to the ordinary mz-tch.

In the drawings, Figure 1 is a side View embodying my invention and showing the approximate size of the igniting pellet. Fig. 2 is an enlarged and sectionalview of the same. tional view of a pellet having only the pyrophoric coating capable of ignition by friction with a specially prepared surface. Fig.

4 is an 0enlarged and sectional view of a pellet in which the combustible material and the pyrophoric material are mixed; the

pellet being ignitible only with contact with a specially prepared surface. Fig. 5 is an enlarged and sectional view of a pellet having the central body portion composed 'of a mixture of the combustible material and pyrophoric material, and having an outerv coating of readily ignitible material.

In reference to the' materials herein, the combustible material includes any material 0r substance suitable for the main body or art of a match; the pyrophoric material esignates the material commonly used for the coating of safety matches; and the ignitible material designates the material used Fig. 3 is. an enlarged and secfor making the friction tips of ordinary matches.

Referring to'the drawings, the central and main portion 6, of the pellet consists of a combustible material, such as wood, felt, or compressed wicking or paper, and preferably prepared by soaking in a solution'of saltpetre and lime-water, and then dried. yThe inner coating 7 ignites by applica-tion of fire or friction with a special surface, as used on safety matches. The outer coating 8, consists of an easily ignitible material, such as applied to the tips of ordinary matches. or of a paste made from mealed powder, phosphorus, powdered glass, and alcohol.

The main body of the pelletabeing prepared in accordance herewith, will then burn for a period of time equivalent to the ordinary match; the saltpetre acting to maintain the combustion, while the limewater determines lthe rate of combustion. The inner coating, ignitible by friction with only a specially prepared surface. is employed only for safety pellets, while the outer coating will ignite upon contact with ordinary surfaces when frictionally applied thereto. For safety pellets, the outer .coating is omitted. Saltpetre and l-imewater impa-rt slow-burning properties. The outer coating is ignitible by va spark or friction, the inner coating by friction only.

an outer coating of readily ignitible matep rial thereon. I l

In testimonywhereof, I hereunto atlix my signature.
