Description

UNITEDSTATES PATENT OFFICE.
AMBROSE H. ROBEN'IHAL, 0! BROOKLYN, NEW YORK.
METHOD 0! SURFACE-TREATING CELLULOID AND THE LIKE.
No Drawing.
To all whom it may concern:
Be it known that I. AMnnosn H. Rosnx- THAL, a citizen of the United States,.resid1ng at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in the Methods of Surface-Treating Celluloid and the like. of which the following is a specification.
My invention consists in a method of treatingarticles having a smooth adhesive surface, such as celluloid. for the purpose of imparting iridescence or the appearance of mother of pearl thereto.
In. practising my invention I may treat such articles, as for example sheets of celluloid. or blocks or other shapes of celluloid for producing the desired appearance, or I may flow a sheet or coating of varnish or celluloid upon paper, wood or other material and treat such sheet or coating to surface the same. Objects treated according to my invention may be applied to'many uses, among which may be mentioned-toilet articles, calendars, fancy box coverings and 1mings, blotter covers and containers of all kinds.
Assuming it be desired to treat a sheet of celluloid to impart iridescenc-e or a mother of pearl appearance thereto,'according to my invention, I first rub upon the surface of the celluloid a combination of chlorid and bi muth. i. 0., I may use bichlorid or trichlorid of bismuth, and continue to rub until a characteristic pearl finish becomes apparent. The length of treatment will vary with the nature of the celluloid, and I preferably use a soft pad of felt or like material for rubbing.
After the treatment with bichlorid Olrtllchlorid of bismuth, the surface of the sheet so treated is coated with a thin layer of celluloid. and this is effected by passing Specification of Lcttersl'atcnt.
Patented Mar. 22, 1921.
Application filed April 1, 1920. Serial No. 370,592.
the sheet through a water bath on the top of which floats a body of 1i uid celluloid. The sheet is passed .fairly quickly through the bath and this treatment converts the pearl finish into ii mother of pearl appearance. When the article emerges'it is permitted to set. which requires but a brief time, and it is then ready for commercial use.
It will of course be understood that the method is the same whether a sheet of celluloid be treated. or whether an article which is merely entirely or partly covered with celluloid or varnish is treated.
I claim 1. The herein described method of imparting an iridescent or mother of pearl appearance to articles having a smooth adhesive surface. which consists in treating the surface of the article with a bismuth combination, and thereafter applying a coating of celluloid to the treated surface.
2. The herein described method of imparting an iridescent or mother of pearl. ap pearance to articles having a smooth adhesive surface. which consists in rubbing the surface of the article with a bismuth combination, and thereafter appl vi11; a coating of celluloid to the treated surface.
3. The herein described method of imparting an iridescent or mother of pearl appearance to articles having a smooth adhesive surface. which consists in rubbing the surface of the articles with bichlorid or trichlorid of bismuth, and thereafter passing the article through a water bath having li uid celluloid floating thereon.
n testimony whereof I have aflixed my signature in resence of two witnesses.
