AnoLr Birnen, or :BEanIn-onnnsnennwnrnn, GERMANY- BRAIDING on rnarrrive 'MACHNE Application led September 21', 1925,Seria1 No. 57,787, and in Germany .October 13, 1924.

rlhis invention relates to braiding machines in which ytwo ,groups of spools revolve with equal velocities but in `opposite directions round the braiding centre, and s the threads coming from one of spools, are beaten by slides moved radially in relation to the airis of the machine., the said slides being provided with threadguides, between the spools of the other group. The essential feature fof Ythe invention consists in the fact that each slide has a driving lever which is moved by means of a stationary ring provided with controlling surfaces.

llVith 'this construction lof the machine it is possible to attain a high velocity in the mot-ion of the slides without the angle of inclination of the controlling surfaces be Y coming too great, and in this way `causing 2U shocks tothe gearing. The high slide velocity enables the angular velocity of the groups of spools to be increased thereby in creasing the output. At the same time the `lhread is protected from damage because between the state of restand the maximum velocity of the thread there Vis a graduated transition. L

in the accompanying' `drawings the invcntion is illustrated by way vof example.

Figure l is a partial sectional eleva-tion of the machine.

Figure 2 is a partial plan.

. Figure 3 shows a partial sectional elevation on an enlarged scale.

et is `a vertical partial sect-ion through another form of the machine.

Fig. 5 is a horizontal section corresponding to Fig. i.

The machine consists of a stationary foot u in which is journalle-d a hollow shaft t) which'encloses a stationary hollow axle c. On the hollow shaft b is mounted a second hollow shaft d. rlhe two shafts b and cl are driven in the same direction by means of bevel wheels e, f and g, respectively from a driving shaft z'.

The bevel wheel g receives its motion from the bevel wheel f through the medium of a pair of spur wheels le, Z which are in the ratio of 1:3.

At the upper end of the hollow shaft (Z is arranged a disc m and at the upper end of the shaft Z) is arranged a` disc n. The disc fm is rigidly connected with a. further disc 55 o. The disc 0 is provided with guides y) and K g for segmental slides r. These slides r are provided on the underside with teeth and in these teeth there :engage radially arranged .toothed wheels Vs which on the othery side mesh with a toothed rim constructed on the disc The disc fo `further, comprises guides for radially Jdirected slides fw. These are in the shapel of a channel fopen at the bottom and are drivenby ymeans of levers 'v and rlink rods The levers o are pivoted on blocks .e which project radially outwards on the d-i-sc o. The levers carry a projection e provided with a Yroller y. The roller is pressed by the action of a spring 2 against `a stationary fri-ng 3 the inner edge-fof which is provided with cani surfaces 4:. Said ring is removably arranged `upon columns 1'3", so that it rcan be exchanged a ring with other cam surfaces for the purpose of producing sev-eral designs. p

f llili-thin the stationary .ring 3 second stationary ring 3 maybe arranged. The ring 3 has cani surfaces il Ion its enteredge .corresponding to v:the cani surfaces 4 of the ring so that a groove vformed for the rollers .y lof the levers rv. The spring 2 is omitted.

Both the rings 3 and 3l may be formed in one 4piece as shown i-n Fig. 4l.

The radial slides u carry tubes 5 which serve as guides for the threads/7 coming from the spools 6. The spools 6 are supported kolii-the underside of the discs m by means of the `blocks 8, Y

The segmental slides r carry upright `spools 9. The threads l()v delivered by these spools and the threads 7 run towards the Vbraiding centre, not shown, at the upper The' end of the stationary hollowaxlle c. method of working of the machine is as follows:

By lmeans of the driving shaft i the two discs m and n are set in rotation, the disc n having twice the angular 4velocity of the disc m. Consequently the toothed rim t on the disc n can set in rotation the toothed wheels s and'hence the segmental slides move round the aXis of the machine in their guides y) and g, which revolve with the disc m, in the opposite direction to the discs m and fn. Consequently the spools 6 and the spools 9 revolve round the axis of the machine with the same velocity but in opposite directions. The thread-guide 5`is displaced inwards by means of the cam surfaces 4 and of the lever o from the position shown in Figure 3 as soon as two spools 9 have traveled past it. l't remains in this position (Figure l to the f guides on said slides, said radially moved slides being adapted to beat the threads co1n-v ing from one of said groups of spools between the spools oli' the other of said groups, a drivfing lever for moving each of said radially moved slides, a stationary ring, surrounding the body of the machine, and cam surfaces 'on said ring for 'actuating Vsaid driving levers.
