Description
Ul ll lEB) JOSEPH P.
BENNETT, OF DULUTH,
ra s M'INNESOTA.
Be it lrnown that l, Josnrn P. BENNETT, a citizen of the Unlted States, resldnw at Duluth, in the county of St. Louis and state of Minnesota, have invented new and useful Improvements in Processes for impregnating lzlatch-Splints, of which the following is a specification.
My invention relates to an improved proc ess for impregnating match splints for the purpose of rendering the splints nonglowing after the matches have been used.
It has become common practice to dust upon the splints, while in a match making machine of the ordinary continuous type, a fine powder such as ammonium phosphate, tor the purpose of preventing the dangerous after-glow when the matches are used. Means for accomplishing this purpose are described in Patent No. 1,326,633, granted to me on the 30th day of December, 1919.
The object of my present invention is to increase the efiiciency of the impregnating process by securing a more uniform coating and deeper penetration of the fibers of the splints by the glow-deterring material.
The usual methods now in practice are dependent for their success upon the adhesion to the surface of the splint of the fine dry powder which is applied thereto. I have found that the uniformity and efficiency of impregnation is much increased by my present process which consists in subjecting the match splints to a cloud of fine powder and then melting and dissolving the adhering powder by the application of steam.
To this end I first pass the splints through a cloud of fine powder, such as ammonium phosphate, which may be done by the means Specification of Letters latent.
IPatented Mar. 29, 1921.
Application filed February 26, 1920. Serial No. 361,545.
pomted out in my patent .above mentioned, and I then expose the splints so dusted to the action of steam, preferably in an inclosed receptacle, whereby the powder is melted and dissolved and the surfaces of the fibers and interstices between the same are thoroughly impregnated with the chemical forming the powder, after which the splints are removed from the steam and immersed in parafin.
The steaming of the powdered splints, in conpmctlon with the other steps above described, results in the economical production of better and safer matches than those produced by the methods of manufacture heretofore practised.
l laving described my invention, what I claim as new and desire to protect by Letters Patent is:
1. The method of treating match splints which consists in first dusting the splints with a glow deterring, impregnating powder, and then steaming the splints to melt and dissolve the powder in the pores and upon the surface of the splints.
2. The method of treating match splints by first dusting the same with a dry, soluble powder adapted to prevent after-glow, then steaming the splints, and finally dipping the same in parafiin.
3. The method of treating match splints which consists in first dusting the same with a dry soluble powder adapted to prevent after-glow and then steaming the splints to dissolve the powder thereon.
In testimony whereof I have hereunto signed my name to this specification.
JOSEPH P. BENNETT.
