MATCH-IGNITION MATERIAL.

No Drawing.

" BURN, a citizen of the United States, and

resident of Short Hills, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Match-Ignition Materials, of which the following is a specification.

I This invention concerns a match-ignition material designed more especially for use with or as an integral part of match re- V ficlent water added thereto to make a stiff ceptacles and the like. a

The material is in the form of a solid block or body comprising a composition of matter, which, when molded into shape and allowed to harden, provides and insures an ignition surface for matches ofdiiferent kinds,to wit,-those that may be struck on any ordinary rubbing surface and those that may be struck on specially-prepared chemical surfaceswhich said ignition surface 7' is characterized by its smoothness, permanence and efliciency under widely varying conditions of temperature and relative humidity.

Ignition material embodying my nvention does not melt or run when it is subjectedto great heat; and when such material is molded into or otherwise applied to a suitable fire-proof holder, base or marginal frame member, which covers and protects the edges and corners of the block, the material cannot be ignited by flame. During extremely high humidity, with relatively high or low temperature or fluctuations of temperature which subject the material alternately to the dew, point, the smoothness and ignition efliciency of the surface of the composition is unimpaired. The block can be immersed in water and cleansed without injuring its-smoothness or shape; the small amount of water the material may absorb when bemg washed drying out immediately after removing it from the water. Such material remains permanently Specification of Letters Patent. I

Patented Dec. 5, 1916.

Application filed April 6, 1915. Serial N 0. 19,552.

mentioned consists essentially, of resin, dextrin, antimony sulfid, plaster of Paris and amorphous phosphorus (or other allotropic form of phosphorus or compound of phosphorus), in certain proportions, the whole belng'intimately mixed together and sufpaste. The mixture is molded into any appropriate form and permitted to harden, the surface of the resulting block or body being smooth, since there is no abrasive material used therein.

The ingredients enterin into the compos 1t1on are combined in a out the proportlo'ns (by weight) stated, viz.

Resin. 4 parts. Dextrin 1 part. Plaster of Paris; 16 parts. Antimony sulfid 12 parts.

Amorphous phosphorus 16 parts.

These ingredients are thoroughly mixed and water is added thereto to make a stiff paste as above mentioned.

As above indicated instead of amorphous phosphorus, any other allotropic form of phosphorus 0r compound of phosphorus may be used as an ingredient of the mixture, without departing from the invention defined in the appended claim.

I claim The herein described match ignition material composed of resin, dextrin, plaster of Paris, antimonysulfid and amorphous phosphorus, combined in about the proportions specified.

Signed at New York in the State of New York this 5th day of April A. D. 1915.
