Description

Patented June 21, 1932 UNITED STATES PATENT OFFICE f JULIUS KAHN, OI" JERSEY CITY, NEW JERSEY, ASSIGNOR TO DO POINT VISCOLOID COM- IPANY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE BABBETTE Application filed January 30, 1931. Serial No. 512,836.

This invention relates to holding devices, and more particularly to holding devices for the hair in the character of barrettes. While not restricted theretothe invention has more particular application to barrettes decorated with cellulose ester plastic, for example pyroxylin plastic.

In the field of pyroxylin plastic articles it is necessary, in a large class of these articles such as barrettes and similar items of adornment, to produce them in such manner that although they embody in their construction an assembly of a metallic body and plastic decorativematerial therefor, they may be produced at a minimum cost, and consequently sold at a minimum price. I have provided a barrette in which plastic decorative material is combined with a metallic body in such manner that the article may be satisfactorily produced at low cost, the resulting article being eficient and rugged.

7 One object of the invention is to provide a holding device having the desirable characteristics above mentioned. To this end and also to improve generallyupon devices of the I claimed.

Without restricting the invention thereto the same is described by reference to the em bodiments thereof illustrated in the accompanying drawing. In the drawing Fig.

1 is a side view of a barrette embodying the invention; Fig, 2 is a cross sectional view taken on substantially the line 2-2 of Fig. 1; and Figs. 3, 4 and 5 are cross sectional views of slightly modified forms of the invention.

Referrmg now in detail to the drawing, the barrette comprises a body'designated generally as 1 and composed of the back 2 and the tongue 3, the body being, preferably, of spring metal with the tongue given a ermanent bias toward pressing against the ack 2. Carried upon the exterior face of the back 2 is a body of decorative plastic 4, this plastic embodying its decorative features in an suitable way as by its coloring, or by inclu ing metallic particles therein or stuck thereto, and so on. Wrapped about the plast1c -vided variously colored metallic body 4 and the back 2 is an envelope of transparent plastic 5, the envelope serving to per- -manently attach the decorative body to the back while not interfering with the exposure of the body 4 to view. As will be understood by those skilled in the pyroxylin plastic art the envelope 5 may be tightly rolled about the back 2 and the body 4 while the sheet or stri 5f plastic forming the envelope is warme to give it a temporary flexibility, whereupon, upon cooling, the envelope remains permanently set in its wrapped form and tightly and permanently assembles and holds together the back 2 and the body 4. If desired, of course, a suitable cement, e. g. a pyroxylin cement, may be used between any or all of the arts of the assembly.

T e detailed character of the assemb! may, of course, be widely varied. Thus, as illustrated in Fig. 2, the envelope ma be in the character of a strip or sheet which although it hooks under the back 2 does not completely envelop it; or, as illustrated in Fig. 3 the envelope may be in the characterofa previously-made tube into which the'back 2 and the body 4 are slipped while the envelope is'warm and stretched slightly, whereupon, upon cooling the tube shrinks upon the back and body. Also the back 2 and the body 4 may be of any desired cross sectional configuration provided they present a sufiicient area for contact with the envelope 5. Thus, as

illustrated in- Fig. 4 the body 4 may be of a' contact being obtained along the sides 'andbottom of the

members

2 and 4. Many other variations embodying the invention will ofcourse, suggest themselves to those skille in the art. 5 v

In making the decorative body 4 of the barrette decorative plastic of any suitable composition, e. g. parts by weight p roxylin 23.6, camphor 8, urea .1, pigment ely diakes). 1., residual solvent (alcohol) .3 is made up in any of the usual ways of making pyroxylin plastic stock and is cut to suitable dimensions for the purpose. The transparent material for the envelope .5 may be similarl prepared, e X-- cept that, obviously, it sho d not contain sufiicientpigment (if any) to materially detract from its transparency, although it may Y be dyed any suitable 00101 if desired. The block of stock 4, and the sheet (or tube) of stock 5 having been thus prepared they may be assembled with the metal member, as previously mentioned. Although the member which has, for definiteness, been particularl described as of metal, it will be plain that 1t may be of other spring material, as indeed, pyroxylin plastic having a suitable resiliency and permanent set. Furthermore, it will be, seen that certain of the advantages ofthe invention may be obtained even though the envelope 5 is not transparent. For example, a construction in accordance with the invention may be used to build up a back of proper thickness for a barrette from a proper acking with a body of plastic carried thereon.

I claim:

1. A barrette comprising a cooperating tongue and back, a body of decorative material carried upon said back, and an envelope of transparent materiaLover-lying said decorative material and engaging said back to hold said decorative material upon said back.

2. A barrette comprising a cooperating tongue and back, a body of decorative pyroxylin plastic carried upon said back and extending substantially throughout the length thereof, and an envelope of transparent pyroxylin plastic over-lying said decorative material throughout substantially the length thereof and under-lying said back, to'hold said decorative plastic upon said back.

3, A decorated barrette comprising, a metal barrette proper presenting a tongue and a. back, a decoration for said barrette proper in the form of a strip of cellulosic plastic carrying a decorative material therein as an element of the composition thereof, said stri lying along said back on the exterior thereo and an envelope of transparent cellulosic plastic enveloping said strip and-back to hold said decoration assembled upon said back while ex osing said decoration to view.

testimony whereof, I aflix my signature.
