PROCESS OF MAKING A NONMETALLIC LACE Application filed April 5, 1928. Serlal'll't). 630,134.

To all whom it may concern I Be it knownv that; 1", Chat. A. MArsoN, a citizen of the United States, and resident of Lynnfield, in the county of Essex and State 5 of Massachusetts, have invented an Improvement in Process of Making a Nonmetallic Lace Tip, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention is a novel, and improved tipped lace made by a novel process, and consists in the treatment of the lace end or part to be tipped, by moldable material, such as is employed in the making of a so called fabrictip and then treating, .compresing orotherwise molding and forming the treated portion to simulate a metallic tipped lace.

In the art of tipping laces, particularly shoe laces, corset laces, and other lacings for use in clothing, it has heretofore been cu's tomary to apply ametal blankabout the end or portion of the lace intended to be tipped,

25 or to treat the lace by impregnating or otherwise applying a suitable substance, composition orthe like, which when dried, set or hardened, would stiffen-the lace sufficiently to constitute a rigid or tipped portion.

In my development of the art of lace tipping, I have devised novel and efficient tipping machines, such for example as that shown by my prior and copending applica tions Ser. Nos. 379,734, filed May 8, 1920; 592,814, filed October 6,1922; 610,142, filed January 2, 1923; and I have also devised novel methods, as well as material'for use in lace tipping, preferably such as is shown in my copending applications Ser. Nos. 474,253, filed June 1,1921; and 610,141, filed January 2, 1923. I find that it. is possible and feasible to utilize non-metallic. material for lace ti ping, which will result in a completed article of manufacture substantially similar in ap earance to certain metallic tipped laces. urthermore, by means of my machines and processes, I can produce such a non-metallic lace tip much more economi- Cally at great speed in production, and very simply and most efiiciently with a high degree of uniformity in the resulting product resembling metallic corrugated lace t1pp1ug. Furthermore, such resulting article, v1z., a

'laceof usua non-metallic corrugated lace tip, is more satisfactory in use anddesirability from the wearers standpoint. I believe that my invention and process, whereby a non-metallic lace tip, particularly a corrugated non-metallic lace tip, can thus be made to resemble a metallic lace tip, and even a corrugated metallic lace tip, is a distinct novelty in this art, and I wish to claim these features ad y.

Referring to the accompanying drawings illustrating my improved type of non-metallic tipped laceand showing the preferred process of making same, 7

F ig; 1 is a fragmentary plan view of a portion of'a lace to be tipped;

Fig. 2 is a view of the lacing after the non-metallic materialis applied;

Fig. 3 illustrates the completed lace; A

Fig. 4 is a cross-sectional view on the line 44ofFig.3;and

Fig. 5 is a cross-sectional view on the line 55ofFig.3.

While I have hereinillustrated a single end or end portion of a lace, and the tipping material applied thereto, it will be understood that I can, and preferably will, pro duce the presenttipped lace by making same in a machine, s uch for example as that shown in my application Ser; No. 592,814, wherein a double lengthpfa lace to be tipped ;i. e i a length suflicient for two end tips ;Y'i's treated and molded simultaneously, this double length being severed or cut to form the two end tips of the lace. It is, however; possible and feasible to produce the present tipped lace by other machines and processes or the like. Furthermore in' the attached drawings I have illustrated the present in: vention as applied to a tubular braided form although it is feasible to produce my non-metallic tipped lace from flat braid used in manufacturing tipped lacing if desired.

As shown in Fig. 1, the lacing 1 is of suitable size and desired color, of tubular form, is supplied and may be drawn from a roll, asillustrated in my said prior patents, a predetermined portion of.

the lacing being treated as indicated in Fig. 2, with a mass of moldable material. Preferably this moldable mater al s applied to the lacing in a partially l1qu1d or mobile state, being in proper form to adhere to the and customary commercial and preferably plied to lacing, preferably to impregnate the fibers of the lacing, and to constitute a suitable mass, which when dry or set, will retain its final form. This material, if of celluloid or of'a composition, such for example as eration.

Heretofore such molding operation on fabric tipped laces has been effected by means of a plain compressing die. The resulting product, however, would not resemble a metallic tipped lace. In my present invention, therefore, I subjected the treated lac-e portion to a corrugated die. which will result in producingan equivalent corrugated structure on the treated lace end, thus simulating almost exactly and with even greater uniformity than is possible in metallic tipped work, a metallic type of lace tip. It will be appreciated. that in the application of metallic blanks to lace tips, it is frequently necessary and indeed customary to form one or more corrugations on the metal, or indentations or the like, which tend to grip or clamp the metal more firmly into the lace material. Thus the public are quite familiar with the corrugated metal tipped lace, and in my present process I simulate this corrugated metal tipped lace, but by making a non-metallic tipped lace. As shown in Fig. 3, the resulting molded fabric tipped or non metallic tipped material, produces a series of corrugations or convolutions, having alternate convexed portions 3 and concave sections at. This extra compression given to the treated end in the formation of the corrugated tip, produces a high degree of compression and presents a finished surface very closely approximating in gloss and finish, a metallic tip of similar contour.

My corrugated non-metallic tipped lace claimed herein is also the subject-matter of my design application. Ser. No. D5437, filed March 12, 1923.

My invention is further described and defined in the form of claim as follows:

The process of making a non-metallic tipped lacing, having a corrugated contour, which consists in applying to a predetermined portion of the lacing, moldable material in plastic form, and thereafter molding said treated portion into corrugated form.

In testimony whereof, I have signed my name to this specification.

CARL A. MATSON.
