BRAIDING-MAQHINE Application filed March 20, 1909.

Specification of Letters Patent.

Patented Dec. 27, 1910,

Serial No. 484,61()A T o all whom it may concern:

Be it known that l, Gts'rAv iNGnNnaHL, a citizen ot the United States, and a re.==i dent ot Vyomissng. in the county of Berks and State oit Pennsylvania, have invented certain new and useful Improvements in liraMing-Machines, o't` which the following,I is a specification.

My invention relates to braiding machines, and-my object is to provide for producing braids having alternate plain-braided and diamond-braided stripes in a more simple and economical manner thanheretoiore.

' To this end my invention consistsin providing a special carrier drive-gear for connecting,` series of ordinary drive gearsin a carrier course, which special gear is adapte Al to automatically change the grouping of the carriers in passing them from one series to an adjoininr series for producing alternately the plain and diamond weaves; as

-t'ully described in connection with the ac' comjianying drawing and specifically pointed out in the claims.

In plain braiding, as is well understood, the threads are vpassed over two under two, while in diamond braiding they are passed over one under -one"; the required grouping` of the carriers upon the horns of the drive-gears for plain braiding being one full and one empty,while for diamond braiding it is two full and two empty. lleretoforebraids havingr alternately arranged plain and diamond stripes have been commonly produced upon .so-Called llereules machines in which drive-gears having six carrier-engaging horns each are employed; such a 1nachine,'when suitably arranged, permitting 0f the proper grouping' for the purpose, of a reduced number oi carriers employed. The mairi'objcct of my invention is to enable an ordinary plain braiding machine having four-horn drivegears to be so used, and with a Jfull set of carriers; thereby greatly increasing.: the speed and economy of production as well as utilizing: for the purpose a simpler and cheaper machine.

Figure l` indicates a simple form of plainand-diamond stripe-braid such as my invention provides tor produeiinf. Fig.' 2 1s a diagrammatic view ot' a carrier course embodying my invention, the changed grouping:r of the ez'n'riers upon the specially connected adjoining series of gears beine; indicated. Figs. 3 and et are detail views of one lorm ol my connecting drive gea-r; and Figs. 5 and (i are similar views of another and freue ally preferable form. Fie'. 7 is a similar view to Fig. 2 indicating afslightly modified arrangement of the course.

Fig. Zindicates a carrier coursecomprisinfr five-horn 'terminal drive-gears a and b at the respective ends, andintervening series of .drive-gears c c and rl fl adjoining the respective terminals a and b, a central series e e e c connected with the adjoining series c c and d ci by my specially formed drive-gears f t' hereafter particularly described. All of the drivegears c Z e and f have like meshing gears, as indicated at q Figs. 8 and 4, and like carrier-engagingr rims divided. as shown, into quarter-sec'. tions provided with carrier-engaging horns; the special drive-gears f however differing from the ordinary gears c (i e, in having one ofA the four horns with which the aI carrier clearance-way m adapted to perlmit a free quarter movement of each of said drive-gears f without engaging the carrier just previously delivered to such clearanceway. In orderthat said special gears f may be conveniently substituted on an ordinary plain braider, for-the usual tour-horn gears, as c CZ e, it may be formed as shown in Figs. 3 and 4, in separate parts fastened together hy bolts a; the four-horn gear W'hich'is to be employed for all plain hraidinp,r being in such case similarlyv made so that the required change'either way can be readily effected by'substituting one gear for the other. A preferable form of this connecting ,gear however, usable for allplain braiding when desired, as well as for regrouping. the carriers to automatically change the weave as described, is indicated in Figs. 5 and 6: the horn-section which is removed to provide'the clearance-way m, beingl in this construction formed. as indicated at c,`0n a separate part o ot the drive-gear, which part as shown is arranged to slide vertically in a suitable guide-way p therefor, so as to be readily adjusted'into operative or inoperative position on the gear.

By referring to the carrier arrangement indicated, in Fig. 2 the etl'ect produced by employingl my special drivegears 7' will be readily understoodr The successive carrier- 5 filled or solid circles therein, it will be seen that, .starting on terminal L and continuing on the adjacent series of ordinary gears c 0 and special gear We have the required arrangement for plain braiding,-na1nely 1 l0 full, 2 empty, 3 full, 4 empty, 5 full, 6 empty,

7 full, 8 empty. It will be noticed however that the carrier at 7 full, which has moved to this position on the clearance-way m of the special gear j' by its own momentum, Will remain at rest in this clearance-way while the gear f makes a further quarter-turn to get into .engagement with it; and that during such further quarter-turn 5 full Will be moved into position 6 so as to place two fulls in succession; While at the same time the point 7 of gear f Will be moved on empty after 8 empty; which action upon successive carriers passing gear f results in the required arrangement for diamond braiding upon the series of gears namely 9 and 10 full, 11 and 1Q empty, 13 and 14; full, 15 and 16 empty, 17 and 18 full. In like manner the carriers are automatically regrouped in .passing the second special gear f so as to again effect plain braiding upon the series of gears el; While in the reverse travel, from right to lett, the same changes are similarly effected in passing the gears f, with the desired result of producing a plain-and-dia- `mond braid having plain edges and a dia- -mond center stripe as indicated in FiO. 1.

Obviously any desired number, arrangement, and width of the stripe etfec'ts may be produced by varying the number and ar- 40irangement of the gears in well known manner. In the slightly modified arrangement indicated in Fig. 5 for instance, provision is made for weaving a diamond-edge ointhe braid product in connection with an adjoining plain stripe.

`By means of my improvement it will be seen that an ordinary plain braider can be readily adapted to produce plain-and-diamond stripe braids with the same speed and economy as plain braids are produced, the full number of carriers which the gears are capable of carrying being employed in either case and With the same speed of travel.

IVhat I claim is: 1. A braiding machine having a carrier course comprising separated series of' like drive-gears having equally spaced carrier-` engaging horns, and a similar connecting drive-gear having one of its horns removed to form a carrier clearance-way whereby the grouping of the carriers is varied in passing them from one series to the other to change the weave.

2. A braiding machine having a carrier course comprising separated series of like drive-gears having four equally spaced carrier-engaging horns, and a similar connecting drive-gear having one ofvits horns removed to form a carrier clearance-Way whereby the grouping of the carriers is varied in passing them from one series to the other to change the Weave.`

8. A braiding machine drive-gear having a carrier-engaging rim equally divided into horn sections one of which is shaped to form a carrier-clearanee-Way adapted to disengage and set back certain of the passing carriers.

et. A braiding machine drive-gear having a carrier-engaging rim provided with carrier-engaging horns on each of three quartersections thereof and With a carrier clearanceway on the remaining quarter-section adapt- GUSTAV DINGENDAHL.
