Application filed March 9. 1918.

To all whom it may concern:

Be it known that I, LOUIS V. ARONSON, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Matches, of which the following is a specification.

This invention relates to matches, and more particularly to a type having certain characteristics which render them particularly desirable for outdoor use, as stated in my Patent 592,227.

One of the objects of the present invention is to provide a match of the above general character which will have a relatively long steady period of combustion. Another object is to provide a match which may be easily ignited by friction on any surface, either dry or damp, and possess qualities of persistent combustibility, that is one which will continue to burn even in a high gale ofwind. A further object is to provide a match which will be waterproof or unaffected by moisture. A further object is to provide a match free from poisonous and objectionable fumes and which, after the period of combustion, will immediately go out without leaving any hot or glowing end. A further object is to provide a match of the above general character which may be safely handled and easily and inexpensively manufactured.

A further object is to provide a match which will not give off sparks when ignited, thereby making it safer to handle around explosives.

Other objects will be in part obvious fromv the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the memhers and in the relative proportionin and disposition thereof, all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same b the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as part of this disclosure, and wherein is showndiagrammaticaliy an enlarged longitudinal sectional View of the match.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Serial No. 221,478.

A match of the above character is preferably made from a stick tipped with a composition of certain potassium salts, phosphorus and lamp black, with a suitable binder, and provided with a waterproof coating. I preferably use one part of potassium chlorate and two parts of potassium nitrate. mixed with substantially sixty parts of amorphous phosphorus and sixty parts of lamp black. The potassium chlorate which may be considered as having a relatively high oxygen content, and the potassium nitrate having a slightly lower oxygen content, may be varled within reasonable limits, as may be desired, as one in a way counteracts the other when combined in the presence of lam black and phosphorus, to provide a relative y slow burning fuse, or match, as distinguished from a more nearly explosive combustion. The lamp black which forms a base has the peculiar characteristic of being relatively non-combustible, and after the potassium salts and phosphorus have burned out, the lamp black, which protects the wood upon which the combustible material is mounted. will absorb the heat, thus allowing the flame to die out suddenly without leaving a dangerous glowing or hot end.

The above-referred to ingredients are mixed in the presence of any desired amount of water and twenty parts of dextrin to form a paste of the desired consistency. whereby when the stick is dipped into the paste the combustible composition will adhere thereto in the desired amount.

In the accompanying drawing, 2 denotes the body of the match which is preferably formed of wood, while 3 indicates the combustible composition above referred to.

It will be noted that this composition extends along the body 2 such a distance as to insure a steady even flame for a period of two to five seconds. as may be desired. The period of combustion however may be varied somewhat by changing the proportion of potassium salts. as well as by the length of the body-portion which is covered by the composition. After the combustible material 3 has set. the match is then preferably provided with an easily ignitible material 4: as shown in my prior patent and treated with any suitable waterproofing solution 5, such for example as shellac or a cellulose solution.

match constructed in the above manner and with the herein stated ingredients is particularly adapted for outdoor use and not only forms an important item of the equipment of soldiers engaged in trench warfare for lighting the fuses of bombs and hand grenades in windy and damp weather, but is also of great value to sailors, hunters and campers who live outdoors, frequently requiring the use of matches under conditions in which ordinary matches.

cannot be used.

It is believed that from the above it will be seen that the present invention provides a match of simple and practical construction adapted to accomplish, among others, all of the objects and advantages herein set forth.

The nature of the compound employed by me is such that it adds to the facility with which the match may be ignited. It is also of such a nature that the head of the match as a whole will crumble and not ignite under pressure applied longitudinally of the head.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A match of the character described consisting of a stem provided with a head ignitible by friction, having the properties of persistent combustibility, said head being madeof a composition including a I relatively small per cent. of oxygen carrying potassium salts mixed with a much larger per cent. and substantially equal parts of phosphorus and lamp black in the presence of a suitable binder.

2. A match of the character described consisting of a stem provided with a head ignitibleby friction, having the properties of persistent combustibility, said head being made of a small per cent. of oxygen carrying potassium salts with a relatively large per cent. of phosphorus mixed with a substantially equal part of non-glowing material.

3. A match of the character described consisting of a stem provided with a head ignitible by friction and consisting of a small per cent. of oxygen carrying potassium salts with a relatively large per cent. of phosphorus mixed with a substantially equal part of non-glowing material, said parts being mixed with a suitable binder and covered with a waterproofing composition.

4. A match of the character described consisting of a stem provided with a head ignitible by friction, said head consisting of a mixture of one part of potassium chlorate, two parts potassium nitrate, sixty parts each of lamp black and phosphorus and twenty parts of dextrin, and all covered with a suitable waterproofing composition.

In testimony whereof I aflix my signature.

Louis v. ARONSON.
