WILLIAM A. FAIRBURN, OF SHORT HILLS, NEW JERSEY, ASSIGNOR TO THE DIAMbND MATCH COMPANY. OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

TREATED MATGI-I-SPLINT AND PROCESS OF PRODUCING THE SAME.

No Drawing.

To all whom it may concern:

Be it known that I, l VILLiAM A. FAIR- BURN, a citizen of the United States, and. resident of Short Hills, in the county of Essex and State of New Jersey, have inverted certain new and useful Improvements in Treated llfatch-Splints and Processes of Producing the Same, of Whichthe following is a specification.

The object of this invention is to provide a simple, economical and eflicient process whereby flaming and non-glowing properti s are imparted to match splints; and to that end I grind a powdered anti-glowing substance into a heavy-bodied oleaginous substance and then incorporate the mixture with an unctuous inflammable material in the presence of heat. This mixture is preferably agitated, or kept in circulation, and the match splints are then dipped into the same and impregnated therewith.

In pmsuance of my invention, (which also embraces the impregnated splints) the preferred anti-glowing substance which I employ is boric acid, and the preferred oleaginous substance into whichit is intimately ground is a heavy-bodied petroleum product, such as petrolatum; the proportion being about, by weight, 2 parts of petrolatum to 1 part of boric acid.

The preferred inflammable material to which the mixture is added is melted paraffin wax, the proportion being about 9 parts of paraflin wax to 1 part of the petrolatumoric acid mixture. The mixture, being preferably agitated or kept in circulation, is maintained at a tempeiature of about 250 Fahn, and the match splints are dipped thereinto and then removed. Such splints are thus efl'ectually impregnated with the constituents of the mixture and as a result the splints possess the requisite inflammable and non-glowing properties; that is to say, the paraffin serves as a vehicle to transmit the flame from the match head to the splint and the boric acid renders the splint nonglowing after the flame has been extinguished.

I do not'limit my invention to the specific materials or proportions herein mentioned; but

Specification of Letters Patent.

Patented Jan. 1s, 1916.

Application filed June 12, 1913. Serial No. 774,314.

What I claim is- 1. A process of treating match splints to impart flaming and non-glowing properties ed paraffin wax at a temperature of about 250 Fahr., and dipping the splints thereinto.

3. A process of treating match-splints to impart flaming and non-glowing properties thereto, which consists in subjecting the splints to a bath'of melted paraflin uith which is incorporated an intimate mixture of petroiatum and an anti-glowing material.

4. A process of treating match splints to impart flaming and non-"lowing properties thereto, which consists in subjecting the splints to a bath of melted paraflin wax with which is incorporated a mixture comprising boric acid ground into petrolatum.

5. As a new article of manufacture. a match splint impregnated with a mixture containing a waxy, unctuous, inflammable material, a heayy-bodied, greasy oleagmous substance arifl 'a finely divided anti-glowing material.

6. As a new article of manufacture. a match splint impregnated with a mixture comprising paraflin wax, petrolatum and finely divided boric acid.
