Patented May 12, 1908. Renewed Septeniber 25, 1907. Serial No; 39%,57'7.

To alt 'itlltl'ilt it may renew-11.:

Be it known that l. Jason .llrnnennu, a

citizen of the United States, residing at Pluhulelphia, m the county of Philadelphiavsnia. have invented uset'ul im n'ovements in o1" which the following is and ritate ot Pennsyl certain new and liraiding ldachmes, a 'specilication.

This invention relates to that class of braiding machines wherein two sets of tbreatl-supplying (ltYlt'telllP rotated in concentr annular paths and in opposite directions to each other, and wherein the threads ol' one set are directed over and under the threads of the other set in a manner to Client the braiding operation, such for example as that shown and described in .Letters Patent ol the l nited States No. (395,746 dated .ilarch its, 1902 to which reference may be had.

The object of this ii ivention is to provide machines of this character with means for introducing an additional thread or threads and directing the latter, by tixed guides, toward the braiding point, between the paths traversed by the th ads delivered from, the two sets of rotating thread-sit lplying de vices, whereby a braid having straight longitudinal threads ir .erwoven with the braided threads may be prmluced, as will be hereinafter fully described and claimed.

in the drawiiigs l igure 1 is a plan view of a portionot' a braiding machine provided with my invention. Fig. 2 is a vertical section thereof, as on the line 2 2 of Fig. 1. Fig. 3 is a similar section, as on the line 3-- 3 of Fig. 1, showing the parts moved to bring one oi the thread guiding devices to this line. Fig. 4 is a sectional development of a on which the upper bobbin carriers run, and adjuncts, line 4 d of Fi 2.

l is the bed plate oi the machine from which projects a. centrelly-arranged hollow tubular post Fitted to this post 5 is a freely rotatable wheel ti which carries a set oi threatl-supplying bobbins 7. The huh 8 ol' the wheel (3 is provided with a bevel gear wheel l) which. coacts with a similar wheel 10 on the driving shaft 11, by means ofwhich the wheel 6 is positively rotated. The wheel (lcarries a series of suitalily-arrangerl. guide devices l2 whieh direct the threads from the as seen bobbins 7 toward the braiding point 13, and, at the same time, raise and lower the said threads during their rotary travel.

In the present instance, the guide devices 12 comprise gear wheels 14 which are rotatably mounted on studs 15 proiecting from brackets 16 on the wheel 6. The wheels 14 are provided with arms 17 carrying thread guiding eyes 18, and they mesh with and are rotated by a lixed gear ring 19 supported by l. ra0l ets I20 projecting from a stationary frame 21 which is supported by the post 5 above the wheel 6. The threads 22 pass from the bobbins 7 through central perforas tions in the studs 15, and. then through the eyes 18 to the braiding pointlil; to the end that, as the wheel 6 is actuated, the gear wheels '14 will be rotated, and their rotating arms 17 will raise and lower the threads .22 during their onward travel, thereby causing the threads 22 to pass between and over and under the bobbins 28 and thus ell'ect the braiding operation, as is well known inv this art.

The stationary frame 2! is provided with a tlange 24- which supports an annular tract:- way 25 on which the upper bobbin or thread carriers 26 run in a direction reversely to the bobbins 7. The threads .37 l'rom bobbins 28 carried, by the carriers 26 are led direct to the braiding point 3. The carriers 26 are driven by a series of pinions 239 which are rotatably mounted on the flange 24 of the stationary frame 21 and which mesh with teeth 30 on the carriers 36, the pinions 29 being actuated by a gear the wheel 6.

By the t'oregoii'ig description it will be seen that the two sets of bobbins 7 and 3. are supported and rotated in annular paths and in opposite directions to each. other: and that the threads 22 from the bobbins 7 are direrted, by the guide devices l2.

thereby producing braid in the usual manner. Thus far the machine is of well known construction and needs no detailed dei-zcription herein.

I desire it to be understood that i do not mechanism above deis substantially the same as described in the patentherel to, as any suitable means limit mysell' to the scribed which that shown and inbel'ore rel'erriu ring .31 carried by.
