To all (on out it mag, concern.-

Be it known that I, Elnora FREUDENBICRG. a citizen of the German Empire, residing at Elberfeld, l3 Ronsdorferstrasse. (:erunrny. have invented certain new and useful Improvements in Single-Thread Lacc liraiding Machines, for which applications have been filed in Gern'iany, December 17th, 1912), under Serial Numbers K. 71.328 VII/25h and K. 71,329 VII/25b and April 9. 1920, under Ser.

Patent 533,369, and Min-ch 30, 1921, patent of addition 21.560 to the aforesaid Patent 553,369; Switzerland, March 31, 192i, Patents98.52$) and 99,719; Italy, March 30. 1921. Patent 197.257, and April (5, 1921, application 301/1369: Belgium, March 31. 1921, Patent 295.2621, and April 5, 1921, Patent 295,526, and of which the following is a specification.

This invention relates to lace braiding machines and more particularly to so called one thread lace braiding machines, comprising as many bobbin carriers as carrier drivers.

The invention relates further particularly to such machines whose drivers are each rotatable clockwise and counter-clockwise.

One feature of the invention consists therein that the race plate having intersecting race openings arranged on a curve shows for each opening a member leaving race way portions between itself and the plate and apart from these members rotatable and arrestable carriers adapted to guide when arrested. the carriers past the outer and inner points formed in the race way plate by the said intersecting race openings.

Another feature of the invention consists in arranging the drivers at equal levels in such a way that the moving drivers can pass stationary neighboring drivers. This is accomplished by providing the carriers with driven parts that are of such thickness that the guiding parts of the stationary drivers guide the carriers past the pointed sections of the track even though the guiding portions of the drivers recede from the track.

Another feature consists therein that from the rack wheels adapted to rotate the drivers each clockwise and counter-clockwise the rack wheel nearest to the driver and surrounding the driver shaft is arranged on a sleeve also surrounding the driver shaft and stationarily arranged in the machine.

Still another feature consists in limiting the motion of the coupling means in such a manner that the springs tending to return the coupling means against the pull of a jacquard apparatus are not able to move the coupling means beyond a certain rest position.

A constructional form of the invention is illustrated in the drawing,

Fig. 1 being a plan view of a track plate with the bottom drivers beneath it,

Fig. 2 is a section on the line A.B of Fig. 1,

Fig. 3 an elevation of two adjacent operating devices for the drivers looking in the direction of the arrow in Fig. 2, the external parts of the one driving device being broken away.

Fig. l is a perspective view of a part of the track plate with the drivers beneath it.

Referring to the drawing a a a at rep resent four successive drivers Whose axis are intersected by a circle If, These drivers are arranged at equal heights as will be seen in Fig. 3. The shape of the drivers is such that the rotating drivers a a can move past the stationary drivers a a without striking against their edges. The points (Z of the outer edge of the track are further away from the circle than the points a of the inner edge of the track. The result obtained by this arrangement is that, even though the drivers are arranged in a curve or circle 6 so that the outer sections of the symmetrical drivers 0 a are further apart than their inner sections, the drivers will nevertheless guide the carriers past the points of the pointed sections of the track in a proper manner with the aid of disks f attached to the foot end of, the carriers 0. It will be seen from Fig. 1 that the distance a; between the inner portions of the drivers a and a is shorter than the distance y between the outer portions of the same drivers. The guide members 7' are disposed on a different circle. 6 from that of the driversv cular in The starting and stopping of the drivers is accomplished in the following manner:

When a rod operated by ajacquard apparatus is pulled in ti c direction of one of the arrows shown in Fig. 2 the rod 9 is either raised or lowered. When the rod 9 is lowered the teeth oi the coupling member h are thrown into engagement with the clutch of the toothed Wheel 2'. The coupling member '/i is a ranged to move up and down but not to rotate on the sleeve is. Assuming that the toothed wheel 71 rotates clockwise. the driver a will be moved clockwise by the sleeve 7? when the coupling member h is thrown into gear with toothed wheel 2'. A disk Z is mounted on the sleeve so as to rotate with it. The disk Z has notches m into which a detent a, which may be rigidly fixed to the coupling fork 0, at times protrudes. When the rod 9 is moved the detent it leaves the notches and wipes over the top or bottom surface or" the disk Z. The upward movement of the rod 5/ coinpresses a spring 7) and another spring 9 mounted on the rod "opposite the said spring remains inactive. The retrograde movement of the rod in either direction is controlled by means oi pins 7* fixed to bars a and cross members i strike against the pins thuspositioning the coupling fork and its detent in a predetermined position preterably at the central portion of the rod. When the jacquard apparatus ceases to operate the coupling member is maintained in engagement with the particular clutch until the 'detent a appears above or below a notch m in the disk Z thereby snapping into ongagement with the notch by the expansion of one of the springs hence the coupling member will be thrown out of gear and the disk Z leaves the driver of, in its stationary position in which it acts as a guide member. The toothed wheel it turns to the left while the toothed wheel 2' turns to the right, so that when the rod 9 is pulled down cansin the coupling member h to engage with he driver a? will be rotated to the left. The toothed wheel, 2' is iournalled on a fixed sleeve or hollow shaft 4) in order to prevent the driver from being caused to execute undesired rotary motion by the constantly rotating toothed wheel 2'. The toothed wheel a may e supported by a supmember '20 n: (.b may be semi cirshape and attached to upright Tl'io drivers y also be enabled to pass each other b some or all of them being arranged "in different levels.

In such cases the drivers may be made broader and the disk 7 may be dispensed with. But in accordance with the invention the points oi? the pointed sections of the outer 'edge of the boibin track will then also have to be further iirom the circle 7 than the points 0? the inner edge of the said track.
