TIPPED LACING.

SPECIFICATION forming part of Letters Patent No. 586,771, dated July 20, 1897.

Application filed Tune 11, 1897. Serial NoA 640,304. (No model.)

Lacings, of which the following is a specification.

This invention has for its object the production of a novel tip for lacings; and it consists in the novel features of construction and relative arrangement of parts hereinafter fully described in the specification, clearly illustrated in the drawings, and particularly pointed out in the claims.

Reference is to be had to the accompanying one sheet of drawings, forming a part of this application, in which like characters indicate like parts wherever they occur.

Figure l represents a side view of the fibrous core with a stiffening-section placed upon it. Fig. 2 represents a view of said core and stiffening-section, together with a tubular former through which t-he core passes and on which the body of the lacing is woven, a portion of said body being also shown. Fig. 3 represents a side view of a portion of a tubular lacing as it appears when woven upon said core and stiffening-section and before it is united to said section by heat and pressure. Fig. 4E represents a view similar to Fig, 3, showing the woven body as it appears after being united to the stiifening-section by heat and pressure. Eig. 5 represent-s a View similar to Fig. 4, showing the united parts centrally severed. Fig. 5 represents a section on line 5 5 of Fig. 5. Fig. G represents a view similar to Fig. 2, the core being omitted. Fig. 7 represents a sectional view of one end of a lacing-body and its tip, made in accordance with my invention, without a core. Figs. 8 and 9 represent a modification of my invention hereinafter referred to. Fig. l0

represents a section on line 10 l0, Fig. 8. Fig. ll represents a section on line ll 1l, Fig. 9.

Referring to the drawings, in the embodiment of my invention therein shown and selected by me for the purpose of illustrating the same, and first to Figs. l to 5, inclusive,

which illustrate my invention as embodied in a lacing comprising a woven body and a brous core or cord inclosed therein, a repy"resents a woven tube which forms the body of the lacing, and l) represents a fibrous cord or core which extends through the body a.

c represents a tubular section of a material which is adapted to be softened by heat, to become rigid when cold, and to adhere closely to the iibers of the bodyan d core when pressed against the same in a softened condition. A suitable material for thc section c is celluloid, but any other suitable material or composition may be used, preferablya cheaper coniposition, such as that which is used for making molded hair-brush backs and other articles.

For the salie of convenience I will designate the section c as composed of a plastic material. The said section is preferably made in the form of a tube, which incloses a portion of the core Z).

In practice the core is prepared for incorporation into a series of lacings by having a series of the sections c strung upon it at distances apart corresponding to the desired length of the lacings to be produced. The core thus prepared and the body c are assembled in any convenient way, such as by weaving the body upon a tubular former ct, through which the core and the section c extend, as shown in Eig. 2, the tubular section c being thus interposed between the core and body.

After the assemblage of the core and body I apply heat and pressure by suitable means, such as by heated dies, at the point where the section c is located, the heat being sufficient to soften the section c and cause portions of its material under the pressure exerted to liow outwardly into the meshes of the body a and inwardly among the fibers of the core b, so that the parts of the core and body along which the section c extends are virtually saturated with the material of said section. lVhen the said material becomes cold, the parts saturated by it become exceedingly stiff. l

The lacings are completed by severing portions at about the middle of their length, as

indicated in Fig. 5. Each lacing has two compacted and stiffened ends or tips if, these tips taking the place of the metal tips ordinarily applied to the ends of shoe-lacings.

It will be seen that the body ce and core b are iirmly united by the plastic sections, so that there is no liability of independent endwise displacement of either part.

The core b may be omitted, as shown in Figs. 6 and 7, the body ct .being woven upon the plastic section, which in this case may be a solid rod instead of being tubular.

In Figs. 8, 9, l0, and 1l I show a lacing-body a2, which is woven as a fiat strip instead of a tube, the edges of the strip being folded or bent over the stiffening-sectiomas shown in Figs. 9 and ll, the parts being united by heat and pressure, as before.

It will be seen that in each embodiment of my invention shown and described the lacingbody is internally stiffened at its ends,-the internal stiffening being in contact with the inner surface of the woven body and interlocked with the meshes thereof by integral roots or tongues which proj ectoutwardly in to the interstices between said meshes. Hence there is a iirm and intimate union between the stiftening-sections and the body' along the entire extent of said sections. Therefore in case of breakage of any stiffening-section its parts will be held together by the inclosing portion of the body, said portion constituting an envelop which is integral with the body.

Having thus explained the nature of my in- Vention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim, and desire to secure by Letters Patent, is-

l. A lacing comprising a woven body, a fibrous cord within the said body, and plastic bonding and stiffening material interposed between the end portions of the core and body and united therewith, whereby the body and core are firmly united at their ends and the ends of the lacing are suitably stiffened.

2. A lacing comprising a woven body, a fibrous core within said body, and tubes of plastic material interposed between the end portions of the body and core and pressed into the fibers of both the body and core to unite their end portions and stiften the ends of the lacings.

The improved method hereinbefore described, of making tips on woven lacin gs, the same consisting in inclosing plastic sections in the end portions of a woven lacing-body and then interlocking said sections with said end portions by heat and pressure.

4. As an article of manufacture, a lacing comprisin g a woven body, and an end-stifener of plastic material placed within the end portion of said body and interloeked with the meshes of said end portion.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this Sth day of June, A. D. 1897.
