CORDED BRAID Filed Oct. l0, 1927 Att nrnegs Patented Mar. 15, 1932 UNETED STATES PATENT; oFFicEi MAX KRISSIEI, OF WYOMISSING, PENNSYLVANIA, ASSIGNOR TO TEXTILE MACHINE WORKS, OF WYOMISSING, PENNSYLVANA, A OORIORATON OF PENNSYLVANIA CORDED BRAID Application led October 10, 192'?. Serial Ne. 225,320.

This invention relates to an improved braid and a machine adapted particularly for producing the same; the complete invention involving the interweaving of simultaneously produced flat and tubular braidings, with a portion of the width of the fiat braiding extending ciametrically of the tubular braiding and interwoven with the latter at spacedapart intersections of the two braidings; as

io fullv described in connection with the accompanying drawings, the novel features being clearly defined in the subj oined claims.

Fig. 1 is a side view, and Fig. 2 a cross-sectional view, indicating a particular integrally 15 formed braid embodying my invention; and Fig. 3 is a diagrammatic view showing the novel arrangement of carrier courses provided in a braiding machine of otherwise ordinary construction, to enable the production io of such novel braid.

A composite braid, similar in a general way to that indicated in Figs. 1 and 2, has heretofore been produced by securing to opposite sides of an ordinary flat braid, as by means of iti sewing, separately made cordbraidings which provide the cord effect particularly desired on opposite sides of the edge portion of the flat braid shown. Effort has also been made to produce such cord effect in an integral construction, by interweaving with the flat braid transverse looping threads arranged to fold around and secure to the sides of the flat braid, suitable longitudinal filler threads, so as to provide a reenforcing longi- 3' tudinal rib on each side of the braid; such integral construction being readily produced upon a known type of braiding machine having a transverse carrier course adapt-ed to N., carry such looping threads across the path of the usual flat-braiding carriers. I have found however that a cord effect having the functional characteristics of the composite braid referred to and which are practically ,1 required in such braid, cannot be provided by such an integral formation of the side reenforcing as is above referred to; and my invention therefore consists in providing for` an actual braided-cord effect integral with the main flat braid, and for satisfactorily producing such an integral structure continuously and rapidly.

To this end I provide for simultaneously producing a flat braid 10, extending the full width of the fabric, and a tubular braid 11 iavmg :i portion 10a of the flat braid extending uiametrally through it so as to be intersectcd by the crossing wall of the tubular braid at two points 13 and 14 respectively, spaced-apart to correspond with the diameter of the tubular braid; the interbraided threads which form the tubular braid, crossing the fiat braid and being interwoven therewith at each of said spaced- apart intersections 13 and 14; and the side portions of the tubular braid which overlie the respective sides of the dianietral fiat-braid portion, forming in connection with said flat-braid portion 10a, twin tubular reenforcements 11a, 11b on opposite sides of the flat braid. To give desired vcord eiiect to these tubularly braided reenforcements on each side of the flat braid, any desired number or size of longitudinal fillers are provided, within each tubular reenforcement as indicated at 15, 15, and also at each circlecenter of the braiding courses as indicated at 16, 16, as desired.

My improved machine for making the improved braid above described, is of ordinary and well known construction excepting as to the special carrier courses provided, and the diagrammatic showing in Fig. 3 therefore simply indicates these carrier courses without unnecessary showing of known detail. The course for the fiat braiding carriers is indicated by the full lines a, while the courses for the tubular braiding carriers are indicated by iight dotted lines and heavier dotted lines b and c respectively; these courses b and c intersecting on the side braiding circles 20-21 and :2Q- 23, but the. carriers in course Z) passing under the race circles 24-25 and race circles .Q6-27, while the carriers in course c pass over said race circles so that all the carriers on courses b and c cross the fiat-braiding course a and interweave with the flat braid forming the top edge of the latter as indicated at 13, and also at a point 14 spaced-apart two race-circles therefrom. Thus the tubular braiding effected on the courses b and c, provides twin filler spaces on the sides of the diametral dividing port-ion 10a of the fiat braid formed; between which portion and the braided side walls of the tubular braiding, desired longitudinal fillers 15 may be introduced so as to form substantial cord reenforcements of desired body and firmness.

In my integrally formed corded braid described, the reenforcing portions provided on the sides of the intersecting flat braiding by the tubular braiding, are strong and syminetrical in formation and effectively protected by braided fabric. The preferred construction specifically set forth may be modified Within the scope of the invention as defined in the claims.

That l claim is:

l. An integrally formed reenforeed braid comprising tubular-braided and flat-braided portions, the latter extending dialnetrically through the former as a partition therein and being interwoven therewith at the spaced-apart intersections.

2. An integrally formed reenforced braid comprising tubular-braided and flat-braided portions, the latter extending diametrally through the former as a partition therein and being interwoven therewith at the spacedapart intersections, and each of the overlying tubular-braided portions being provided with fillers to form cord reenforcements on opposite sides of the partitioning flat-braided portion.

ln testimony whereof I aflix my signature.

MAX KRISSIEP.
