BRAID FOR BINDING.

SPECIFICATION forming part of Letters Patent No. 363,627, dated May 24, 1887.

Application filed June 13,1885. Serial No. 168,571. (Specimens) Patented in France August 11. 1883, No. 156,896; in England Maylll, 1884, No. 1,93 and in Germany May28,1884, No. 31,006.

To all whom it may concern:

Be it known that I, MARIE HYAOINTHIE FOUILLET-CHEVANCE, a citizen of the French Republic, and a resident of Neauphle-le-Chateau, Seine-ct-Oise, France, have invented certain Improvements in Braids for Binding, (on which invention Letters Patent have been granted in France August 11, 1883, No. 156,996; in England May 19, 1884, No. 7,988,

10 and in Germany May 28, 1884, No. 31,006,) of

which the following is a specification.

My invention relates to an improved braid for binding the edges of fabrics, and especially the fabrics of garments; and the object of my I5 invention is to provide, as an improved article of manufacture, a flat braid with a permanent longitudinal fold parallel with its edges, whereby the braid may be the more easily applied to the edge of the fabric to be bound than can the ordinary braid, and whereby a better and neater finish may be produced in the binding than can be produced with braid as ordinarily made and applied.

My braid is substantially a flat web with a 5 selvage at each edge and a third selvage along the line of the longitudinal fold on the outer face of the web or braid. This latter selvage is formed in the braiding of the fabric or web on the machine, and it serves to form a finish at the bound edge when the braid is applied to the fabric, as well as to determine or form the fold in the web during its manufacture.

In the drawings, which serve to illustrate my invention, Figure 1 is a perspective view mp resenting a piece of my improved braid as it comes from the machine with the permanent fold formed therein. Fig. 2 is a cross-secti0n of my improved braid as it appears Whenflattened out. Fig. 3 is a perspective view rep 4 resenting my improved braid as applied to the fabric to be bound. Fig. 4 is an enlarged diagram, designed to illustrate the formation of the selvage at the fold in the manufacture of the braid.

a or represent the two wings or plies of the web forming the braid, separated by the selvage 1), formed on one face of the web along the line of the fold and parallel with the two selvages c c at the respective edges of the web.

In Fig. 3 (Z (Z are the two thicknesses or plies of fabric to be bound, and 6 represents a single row of stitching along the edges of the braid, whereby it is attached. here the longitudinal fold is in the center of the web, as herein shown, a single row of stitching will serve to attach the braid.

In the manufacture of my braid I employ a machine very similar to that in common use, the dislecarriers for thespindles being the same as those commonly e'mployedthat is to say, the terminal carriers each having five notches for the spindles and the other carriers four notches-except that at a point midway between the terminal carriers I substitute a three notched carrier for the usual four-notched carrier, and exterior to this latter I place a carrier with seven notches. The purpose of this change of construction is to cause such a movement of the spindles in their travel from one end of the series of carriers to the other as will produce the selvage b.

The diagram Fig. 4 is designed to illustrate the movements of a spindle in its travel from one end of the series of carriers to the other end, and back again to the starting point. In this diagram 1 1 represent the course of the spindle carrying a thread as it moves to the right. \Vhen it reaches the proper point in the web, it entcrsthe eXtcriorly-arranged carrier with seven notches, and is carried around exterior to the web, forming the loop a", which ultimately becomes the selvagc b. 2 2 repre sent the course of the spindle on its return, moving to the left. On its return it doesnot enter the seven-notched carrier, but is trans ferred by the three-notched carrier at y to the carrier of the regular series at the left. This formation of the selvage I) imparts a folded form to the web, as seen in Fig. 1, for reasons that will be obvious.

A machine capable of making this braid is fully described in my pending application, Serial No. 218,685, filed November 12, 1886.

The-advantages of my braid are, first, that it has the form permanently impressed on it in the manufacture that it should have when applied; second, that it may be applied more readil y and smoothly than ordinary braid, and

with very little skill; and, third, that it gives to the fabric or garment bound afinished edge thinner and handsonier than can be produced with the ordinary braid. The longitudinal fol% need not be in the center of the braid or We I am aware that triradiate webs or fabrics have long been braided or woven, and to these I make no claim. My braid is not triradiate, and a Web or fabric of this kind would not serve the purpose for which my braid is designed.

Having thus described my invention, I claim- 7 As an improved article of manufacture, a binding-braid having a permanent longitudinal fold parallel to its selvage edges, and having a selvage, I), along the line of said fold on the outer face of the braid, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
