ROBERT CARL RAI-IM, OF WYOMISSING, PENNSYLVANIA, ASSIGNOR T0 TEXTILE MACHINE WORKS, OF WYOMISSING, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA.

BRAIDING-MACHINE.

To all whom t 'may concern:

Be it known that I, ROBERT CARL RAHM, a citizen of the United `States, residing at Vyoinissing, in the county\ of Berks and State of Pennsylvania, have invented certainl new and useful Improvements in Braiding-Machines, of which the following is a specification.

My invention relates to machines suchas are commonly employed for producing braided fabrics and consists in an improved construction comprising a circularly grouped series of carrier courses which respectively overlap each other, upon which several series of carriers are operated, as fully described in connection withythe accompanying drawings, the novel featres being specifically pointed out in the clairns.Y`

Figure 1 is a plan view indicating the main portion of a machine of the braiding typein which my invention is enibodied'r-in preferred `form; the normal courses of the.`l several series of carriers being shown. Figs.

2 and 3 are corresponding diagrammatic views indicating certain variations in tlie travel lof the carriers upon'the several courses as determined by operation of the switch mechanism provided. Fig. 4 indi- Cates a piece of fabric of varying cross-sec tion producible upon my improved niachine. Fi'gs. 5 and 6 are enlarged crosssections on the lines 5-5 and G-G respectively of Fig. L1. Figs. 7 to 10 inclusive are diagrammatic views indicating how the relation of the stripes is varied.

The machine indicated in the drawings is a square stripe-braider, adapted to normally produce a fabric which is square in crosssection as indicated in Fig. 5; such braid being-provided, when desired, with a central filler or warp, as is indicated at 2 in Fig. 5, though this filler may be omitted particularly in the special braiding of varied cross-section indicated in Figs. 4, 5, and 6.

The machine is provided with four similar ,carrier courses, marked respectively a b c and cl, arranged in a linked Iseries around a central plate-.portion which is provided wi,th,fan opening 5 adapted to serve as a /filler or-warp passage-way. Each of these Specification of Letters Patent.

Application filed August 8, 1914. Serial No. 855,751.

courses intersects two adjacent courses of the circularly arranged series of courses, `at points 6 7, 6 7, and extends into them so as to form what I term overlapping portions 8 of. the courses; each of said overlapping portions embracing, as indicated, two linking racejcircles, 101, 10a, of the respective intersecting courses, which circles may be out out of said courses by carrier-switchlng means when desired.

hEach of the courses i b c and d is provided with a series of carriers, marked respectively el b1 c1 and d1, which traverse their own courses only (Fig. 1) to produce a product of. square section such as indicated in Fig. 5; all of the carriers however being cooperatively driven as usual by a train of carrier drive gears 10, 10a. The gears 10 are so marked to distinguish them as being located within the overlapping portions of the courses, and also as being provided with warp-thread openings 11, through which warp-threads adapted to serve as linking connections may be passed; it beipg understood however that all of the gears may advantageously be provided with such openings so as to permit of employing filling warps when desired. The separate series of carriers operating upon adjacent courses are respectively carried around such warp threads at 10", 10 when the separate products of the different series of carriers are to be linked together in tubular form as indicated in Fig. 5; while warp threads at other points may be utilized when the normal course of the carriers is changed, as hereinafter described.

In making a product of square section as indicated in Figs. 1 and 5. the several series of carriers e b1 c1 fl thus produce stripes forming the four walls of the fabric, upon their respective courses a, c and (l, while the warp threads which pass through the drive gears 10n serve to link together said walls at the four corners. To provide for giving greater body or strength to the fabric, a filler or core warp may be supplied through the central passageway 5, around which filler the several series of carriers forming the inclosing walls will operate; additional liller or warp threads bemachine.

ing introduced it desired, through any or all ci the drive By employing different yarns upon the several series of carriers, the stripes forming the u'alls ot a tuhularly-ormed product. such as has been described, may be attractively Yvaried in color or appearance as desired. My invention however provides for also varying the form or cross-section of the fabric produced; this being accomplished hy diverting the carriers temporarily from their normal courses so as to produce ditferent determined ellects, as will novv he described` 1illhen the carriers al on course a, reach the point of intersection 6 with the adjacent course b, provision is made for diverting them, hy means ot a switch 1.5 as indicated, from their normal course a extending across into course b; so that instead of traveling around the Warp threads extending through the openings in drive gears l()a of the. overlapping portions 8, the;v will travel (see Fig. 3) on the course 7) an equal distance., to the point of intersection 7, Where another switch 20 is provided to return them to their normal course a. The connecting warp threads at 1()a between courses a'. end b, being thus cut out, a dat instead of tuhularly formed product will result. ther warps may he introduced to give desired Jforni to the edging stripes of the flat fabric.

As shown in the drawing, similar divert-- ing switches l5, and returning switches 20, are provided `at all the intersections 6 and 7 oi, the overlapping courses; a double returning svfitch 202* being convenientlyv used at the common center of thel circularly arranged series of courses, which switch is provided with acentral opening forming the filler passage-way 5. Crdinary switchoperating means are provided as indicated for automatically setting these' switches required to produce. determined effects.

It will 'he ree-.dily understood that either tubularly-fornied or flat stripe fabrics ot uniforn'i cross-section throughout may thus be readily produced as desired. ln addition to this however a changing product of varied cross-section at different portions of its length such as indicated in Figs. e, 5, and (i, may be produced on in v improved is accomplished, by intermittently exchanging the travel of the carriers as indicated in Figs. l, and 3; the product being tubularly formed or liat according as the cr iers are made to traverse the courses as indicated in Fig. l, or as indicated in Figs. Q or 3; and the edging stripes or beads of the fiat sections being varied ecco, ng t e carriers diverted Yetvreen cours-s end or rnl c. or c a', or i and f This mechas more specifically indicated by the diagrammatic vieu's Figs. 7 to 10, from which it will be seen that ii3 dillerently colored yarns are employed on theseveral series ot carriers these will successively appear on the. edging stripes or heads ol' the different flat sect-ions so as to produce variegated effects. The carriers on each course may travel in one direct-ion only, thus merely7 t-urninfr the carrier threads around the linking warp threads without crossing them as in ordinary braiding operations. i

The particular construction shown may obviously be readily modified without departing from my invention; as for instance by changing the number of tuhularly linked courses employed, or the numbers of carriers employed in the different courses.
