SPECIFICATION forming part of Letters Patent No. 278,669, dated Application T at whom it may concern:

Be it knownthat we, EUGENE RAFER and EDMOND RAFER, both-citizens of the Republic of France, and residents of Saint-Ohamond, I France, have invented certain Improvements in Braiding-Machines for the Manufacture of Braid, Stay-Laces, &c., (for which we have obtained French PatentNo. 118,155, April 28, 1877; German Patent No.12,319, J uly16, 1880; British PatentNo. 2,510, May.26, 1880, and Italian Patent No.- 11,264, May 27, 1882,) of which the following is a specification.

Our invention relates to a braiding-machine in which a series of rotating carriers are com- I 5 bined withtraveling bobbinholders traversed by said carriers and automatically transferred from one carrier to another; and the main object of our invention is. to so construct a braiding-machine of this characterthat the bobbinholders will be transferred from one carrier to anotherwith the least possible shock, noise, or friction, and without liability of the threads breaking. This object we attain as more fully described hereinafter.

In'the accompanyingdrawings, Figure 1 is a sectionalplan view or diagram of sufficient of abraiding-machine to illustrate our inven tion, the carriers 1 and the gearwl1eels being omitted and the notched disks shown in dot- 0 ted lines. Fig. .2 is a vertical section of one of the rotating carriers for the bobbiirholders, drawn to a smaller scalethan Fig. 1.

mounted on a fixed circular base or plate, B, to which are secured as many stationary vertical spindles I) and fixed cams G O and O C asthere are rotary carriers H for the bobbinholders, 't'our being shown in the present in stance. Eaeh'earrier H consists of'a hollow spindle mounted and free to turn on the fixed 5 5 spindle D, and having notched guidingdisks m m, and a pinion,'N, Fig. 2, gearing into a similar pinion on the adjoining carrier, whereby motion is transmitted from one tothe other, rotary motion being imparted to any one of tlie pinions, in the first instance, by suitable gearing from a driving-shaft, N, as indicated by dotted lines, for instance, in Fig. 1.

To bearings in the disk m and pinion if of each carrier are adapted vertical gripper-bars A, Figs. 3'' and 3 five being shown on each of the end or return. carriers H, Fig. 2, and four on each ofthe intermediate carriers. Each gri1:)per -bar A carries a pair of gripping-claws, G, and has at its. lower end a cranked portion, M, adaptedto the groove in the fixed cam O, (or O.) Each disk m m has as many semicylindrical notches 0, Fig. 2', in its edge there are gripper-barsA, and in'nnediately adjacent thereto for the purposeof receiving the 75 stemsf of the bobbin-carriers F, Figs. 2 and 4", which are temporarily held in the said notches by the claws G of the corresponding gripper-bar A. The carriers are so timed in their movements that the notches in the disks of adjoining carriers always come opposite each other, Fig. 1. Each holder F carries a bobbin or spool, F, of yarn or thread, and there are as many bobbin-holders as there are tobe strands of thread in the braid to be made, nine of these holders being shown in Fig. 1, Each of the intermediate cams, C C, has i only a single cam-groove to control (through the cranks M) the opening and closing of the ,four gripper-claws in each revolution, while the end or return carriers are somewhat larger, and each has five gripper-bars and five notches o in each disk m, (m,) with a cam, 0, having double grooves E E and switches, Figs. 3, j 4, and 4, to keep each of the gripper-claws of 5 that carrier closed during one revolution. and 7 open during the next. For this purpose each cam O isprovided with two switches, P P,

pivoted at p and 1), respectively, on the line of the dividing'rib between the two grooves E and E, Fig. 4f.

Supposing the carrier to be traveling in the direction of the arrow, Fig. 4", and M to represent the crank of one of the five gripperbars, the switches being in the position shown, thecrank M will be guided into the inner groove, E, by the switch P, and as it passes on will throw the said switch to the position indicated by dotted lines, and the four succeeding crank-pins will so act on the switch P that by the time this crank M gets around the groove E to the position shown the switch P will be in the position indicated by dotted lines, so that the said crank-pin will on this succeeding revolution be transferred to and travel in the outer groove, E. \Vhen the crank V of'a gripper-bar A is traveling in the outer groove its claws G are in the .closedeposition to hold the stem f of a bobbin-holder, F, in the notches 0 of the carrier-disks m or, while when the crank M is traveling in the inner groove, E, the claws G are open to release the bobbin-holder. The switches P P are of such a length that the crank-pin of one gripper-bar comes into contact with one end of a switch just as the preceding crank-pin is about to leave the other end, and thus rebounding of either switch into the wrong position is prevented. I

Supposing the parts to be in their several positions indicated in Fig. 1 and the several carriers H rotating in the directions of their arrows, we will explain the path taken by one of the bobbin-holders F, with its bobbin and thread to form the braid, with the other threads simultaneously traversed in a similar manner:

Beginning with a holder F at the position 5, the saidholder being held by the gripper-claws '(lto the rotating carrier No. 1, the carrier 1 will traverse the holder untilit comes into line with notches 0 in the disks of carrier No. 2, when the cam of carrier No. 1 will have so operated the crank of that gripper-bar that its claws will release the holder F, while at the same moment the gripper-rod A on carrierNo. 2, immediately opposite, will have been closed on the said holder to clasp it to the rotating carrier No. 2, which will traverse it in the direction of the arrow. (See position 6.) Vhen this holder comes into notches in the disks m m of carrier No. 3 the grippeirclaws of No. 2 will open and release the holder, while at the same moment gripperj aws on No. 3 will close and clasp the holder to No. 3 carrier and traverse it in the direction of its arrow, as indicated at positions 7 and 8, all. the way round until it comes to the position 9, when the crank ofthe gripper-rod A will be transferred from the outer cam-groove, E, to the inner groove, E, Fig. 4', so as to open the claws and release Itis then carriedpartially around to No. 1 and transferred to the latter, and partly around No. 1 (see position 10) to No. 4, (see position 11,) and, owing to the double cam 0, carried round No. 4 carrier back to No. 1, thence to No. 2 and No. 3, as before, all the other-eight holders F being at the same time traversed in and out in a similar manner. By these means the bobbin-holders are traversed and transferred from one carrier to another without shockor noise, and without breakage of 1 threads.

It will be observed, on reference to Fig. 1, that in each of the intermediate carriers (Nos. 1 and 2) two diametrically-opposite grippers havetheir claws facing in one direction with reference to the rotation of the carrier, while the other two have their clawsfacing in the reverse direction, and also the two diametrically-opposite grippers of one pair have their cranks M about at right angles to their claws, while the two grippers of the other pair have their cranks nearly in line with the claws. The reason for these differences in the set of the grippers is that one pair transfers the bobbin-holders in one direction while the other pair transfers them in the opposite direction. Thus'the two grippers of No. 1, which have their cranks at right angles to their claws, transfer the bobbin-holders from the carrier No. 2 to the carrier No. 4, while the other pair are for transferring the holders from No. 4 to No. 2 again.

I Instead of using pivoted switches P P on the double cams C G, we may make use of the stationary switch-cam illustrated in Figs. 5 and 6. It will be seen, on reference to these figures, that thedividing-rib between the grooves E E is cut away at z z, and at this point is inserted a stud, a1, projecting slightly above the bottom of the groove, and having two curved channels, 1' 0', cut in its surface crossing each other, and each opening on one end into the inner groove, E, and at the other end into the outer groove, E. To these grooves is adapted a traveling shoe, 5', Figs. 5, 6, 7, and 8, having on its under side a rib adapted to enter the cross-channels r r" to guide the shoe, in its rotary motion, from the inner groove to the outer groove, and from the outer to theinner one, as will be readily understood. This shoe has a recess in its upper face for the reception of the crank M of the gripper-bar, which is thus operated as before described.

We claim as our invention- 1. The combination of the rotary carriers hav ing notched disks for the bobbin-holders, with a series of cranked gripper rods, A, mounted in said, carriers, and stationary grooved cams adapted to operate said gripp er-rods, substantially as set forth.
