Patent 301/1213; Holland, March 24, 1921,k

Patent 11,255; Belgium, March 31, 1921, Patent 295,263; Czechoslovakia, March 29, 1921, application P. 2307/21), of which the following is a specification. Y

This invention Y relates to la-ce braiding machines of the kind in which there is one bobbin for each driver, i. e. to so-called single thread lace braiding machines.

The invention deals with the longknown problem of producing machines whose carriers are arranged to turn to the right and l left and whose drivers are arranged in a circle or similarly. This problem is solved by associating special guide members with the arrangement that renders it possible to turn the drivers to the right or left. These guide members are-made to move into and away from the carrier track and when they are moved in they .prevent the carriers from leaving the driver on which they are to travel. The specic manner of accomplishing this in accordance with the invention consists in certain guide members which, in conjunction lwith the neighbouring drivers, form circular tracks, being moved out of the planes of the feet of the carriers when the carrier drivers are brought into engagement with the driving gear by `which they are rotated vto the right or left. The said guide members for two neighbouring drivers may be combined in one piece and the edges ot the guiding portions of the guide members and of thefeet of the carriers may be bevelled.

Arrangements are also made by which the i coupling members which give rise to right hand or left hand motion can only be thrown out 'of gear at the moment the particular driver has completed the desired rotation even though the jacquard mechanism may have previously ceased to exert its pull. The coupling of the driver with the various rotating driving wheels may be effected in one and the same direction by means of jacquard apparatus, and the guide member may be arranged to be indirectly moved out of thetrack of the carriers whenever one of the two jacquard pulls operates.

Another feature of the invention consists in one of the driving wheels for operating the driver being mounted on a special sleeve which prevents the driving wheel from imparting undesired rotation to the driver. The sleeves may be attached lto small standards which also have parts that maintain the coupling in its position of engagement until the driver has reached its proper vposition.

A constructional form of the invention is. shown'in the drawing in which Fig. 1 isa section through a driver associated with itsv coupling and holding devices and adapted to be rotated to the right and left.

F'ig. 2 is a sidey view of Fig. 1 observed in the direction of the arrow.

Fig.v 3 is a plan view of the track plate.

Fig. 4 is an elevation of the assembled machine with all its accessories. i

Fig. 5 is a plan view of the machine according to Fig. 4 showing the direction of movement of the driving wheels.

Figs. 6 and 7 show diiierent ways of ,driving ythe toothed wheels arranged to be brought into gear with the drivers.

Fig. 8 is a perspective view of a movable guide member.

Y The drivers 1 of the machine are located in the track plate 2 and have recesses each of which has two driving edges 3. 'Each driver 1 is rigidly connected or integral with a sleeve 4 associated with coupling members 5 and 6 adapted to move up and down on the sleeve whilst being prevented from r0- tating around the same., To this end the sleeve 4 is made with corners as shown in Fig. 3. The coupling member 5 is adapted to engage with the clutch of the toothed wheel 7 and the coupling member 6 is arev CITI wheel 8 so that the driver 1 is rotated in different directions according as the coupling member 5 or 6 is thrown into gear with its corresponding toothed wheel 7 or 8 respectively.

The coupling member 5 (Figs. 1 and is in 'engagement with a forli E) which has a sleeve-shaped portion 92l that is lined by a screw to the ro( l() so that, on a downward pull being exerted on this rod by means ot the jacquard apparatus, the coupling inembcr is inoved'by the torl; i) into engagement with the toothed wheel 7. After the tori; i has travelled downward a certain distance its sleeve strikes against the lateral projection 11 ot a sleeve 12 which is adapted to move up and down and has a plate 13 (Fig. with an upwardly extending` proj ection 14s. This projection 1l is adapted to enter into the notches 17 in a disk 15 lined by screws 16 1) to the driver 1. lllhen the projection 1l enters a notch 1l' the driver 1 is prevented from executing an undesired rotary movement aio'und .its axis.

The sleeve 12 is arranged to move up and down on the rods 18 and 10.

Arranged at the right ot Fig. 1 is a standard 19? provided with projections 2O and 21 that protrude into recesses and 23 in the coupling members 5 and (l respectively, and which permit or downward niovement of the ,coupling members and (i when the said recesses are located above the projections 20 and 21.

By the pull exerted by means of the jacquard apparatus on the rod the coupling nieinber 5 is lirst movedl down until the prejection has passed through the recess or notch 2O in the upper annular ridge ot the coupling member and then the sleeve 9a ot the tori; strikes against the located projection 11 of the sleeve 1:2 and at the saine time the teeth ot the coupling member 5 come into enga-gement with the clutch ot the toothed wheel 7` and the upwardly extending projection 14 leaves the cavity 1i' and the guide member 13 moves out ot' the path ot the toot 33 ot the carrier.

i'lhen the pull exerted by means oi? the jacquard apparatus ceases the coupling member 5 is retained in its position of engagement by the projection 2O until one ot the notches :22 appears beneath the said projection, when the spring 24 will be able to push the rod 10 with the arm 9, and theretore the coupling` member 5 upwards.

The rod 10 is provided with a pin 25 to enable it to be operated by the spring The `lateral projection or arm 11 ot" the sleeve 1Q and the plate 13 with the projection 111 are pushed upwards by a spring 26 when the pull exerted by the jacquard apparatus ceases.

The engagement oit the coupling member 6 with its correspondingl clutch is eitected by a forked arm 28 projecting` trom a sleeve 2T lined by a screw' to the rod 18. llfhen a pull exerted on the rod 18 by means ot the jacquard apparatus the part 12 is moved downward by a collar 99 after the projection 21 has passed through the notch in the upper annular ridge ot the coupling member (i. At the saine time the projection 1st is moved downward so as to leave the corresponding recess 17 in the disk 15.

When the puil exerted by means ot the jacrpiared apparatus ceases the paits 2i, 21% and the coupling meniber 6 are moved upward by a spring 30 and restored to their normal positions as soon as the notch l appears beneath the projection 21. 1n this case also the part 12 is restored to its normal position by the spring 25.

As will be seen from Fig. 1 the toothed wheel 'l is arranged on a sleeve 51 supported b v the pillar 1S). By this arrangement the toothed wheel i' is prevented troni imparting undesired rotary motion to the driver which might happen it' the toothed wheel T were directly journalled onthe pillar.

in addition to the upwardly extending projections 1d the parts 13, Fig. rave curved portions 32 which, in conjunction with their neighboring disk, torni a coniplete circular track when the plate 153 is in its raised position. lt is thus seen that when the plate 13 is drawn down the carriers are enabled to rotate upon the driver corresgondinp` to the said .downwardly niovef. plate whilst their access t0 the neighbouring driver is prevented by the cnrved portions 32 ot the neighbouring plates on account ot these curved portions still being in their rained positions. rhe curved parts 32 arel preferably bevelled so that the carriers will, it necessary, slide oil' these parts when the plate 123 is raised and move in between two neighboring plates 13. rlfhe toot Fig. il, ot the carrier may be made conical tov the same purpose.

In Fig. 4, 34 is a belt pulley by which the machine is driven. rThis pulley rotates a gear wheel 5) which drivrs a large toothed wheel 36 by which toothed wheels 37D, SlT are rotated. The toothed wheel 37 tansniits its motion to a set et lower wheels (Figs. 5 and whilst the toothed Wheel 37* imparts its motion to a set ot upper wheels T (Figs. 5 and 7). By this means the upper wheels ot' each driver are rotated in the opposite direction to the wheels ot the lower di ivers.
