9 a whom it Way i coime'm c itknown that wefEM'IL' BENTE and 1 PAUL STUIILMANN, CIt1ZeIIS Of the German 1 Empire, residing: at B armen, Germany, have i nvented certain new and "useful Improve ments in Lace Produced on the Single l hrcad Lace-Braiding *Machmey of which the following is i a specification.

Our invention relates to the production of laceyand more particularly to lace made on the single-thread braiding machine, and

v of which the groundwork consists avholly or in art of triangulari meshes.

ne object of our invention is to produce:- -laceof the statedcharacteristics in an eX-jeeptionallyreoonomio and-rapid-manner by I wforew'maybe produced on a small machine.

reason of the relatively small number-and the relatively short lengths-of the threadsrequired. Another object of this invention as to produce a lace of the character set forth which will resistto an eminent degree distortioning influences, to i which: the lace may i "be subjected in handling,'byreason ofthe threads being-firmly interlocked at the crossiing points'of the network.

-Vl ith these-and other objects. in "View our invention' comprises the: particular steps hereinafter fully desoribed and'set forth in the appended claims.

Towthe ground of thelaceanydesired patterns of the type producible on the singlethread lace-braiding machine, for example,

tufts, ispiders, leaflets or the like, maybe provided, thus rendering the 'new' laice particularly valuable.

Our :lace and 'the 1 process of making the same are fnllyset: forth .in the followingdescription, reference "being made to the annexed drawing, which illustrates, by way of example, two embodiments-of the lace, and in which Show Fig. 1 a part of a :laceprovided with a tively wide-meshed net consisting of diagonally arranged threads 1, 4, 7, 10, 13, 16 Acrossing one. another .at certain intervals. Said diagonal threads serve like the weft ofaWeb to connect thei longitudinal: strips or, Z), c; d, e and to lock them in'theircorrect distances. For thisrpurpose the diagonal 'threadsl, 1, 7,10,13, and 16 are at their crossing points braidedly connected to the said "longitudinalstrips by all crossing points A being -in'the example shown, embraced b'y aa pair of the longitudinal threads 2, 3, '5, 658, 9, 11,12 and 11,15. By this means a firmvlaoeaground is obtained, which on a glven -width contains only a oomparatively small. nun'iber-ofthreadsand which there- 'I lurthermore the quantity of thread-material *necessary for a. given length of the lace 'is "very small. -Finallyonly "part of thethreads usedw in forming the-new groundwork need to'be somewhat heavily tensioned, whereas the other partimay be rather lightly tension'ed. Gonsequentlythenew lace can =l e partly manufactured from; comparatively weak and therefore cheap threads. In Fig. :1. those threads which may be lightly tensionediarema'rkedybyufine strokes of the pen,

while the heavily 3 tensioned threads are marked by-bold strokes. As seen in Fig. 1 all' the diagonal threads are lightly tensioned, while most of the longitudinal strips consist of a pair of heavily tensioned threads. .The longitudinal strips may,however, be

" formedeaohof a heavily tensionedtln-ead andofa lightly tensionedthread' as is the "case with the strips 5 and d.

To the laced-ground described patterns ofiithe type prodnci ble by hand-work or on the-singlethread lace braiding machine only, for example, tufts, spiders, leaflets or the like may be applied. In the example shown in Fig. 1, a tuft B is worked into the lace. This tuft consists of four heavily tensioned threads 5, 8, 9 and 12 taken from the strips 6, 0, (Z, and of four lightly tensioned threads 1, 6, 11 and 16 taken partly from the strips I), (Z, partly from the wide-meshed net which connects the longitudinal strips. The said heavily tensioned threads 5, 8, 9, 12 are conducted right through in the longitudinal direction of the tuft and spaced apart in the transversal direction, while the lightly tensioned threads 1, 6, 11 and 16 run continuously to and fro in the transversal direction of the tuft B between said four heavily tensioned threads. Both groups of thread forming the tuft being thereby interlaced in a weblike manner, the lightly tensioned threads at the same time crossing one another in the space between each two adjacent threads 5, S, 9 and 12. Of course, instead of a tuft, a leaflet, that is some sort of tuft with pointed ends, or a spider or a similar pattern may also be applied to the lace ground.

Fig. 2 illustrates the formation of the new ground-work on the single-thread lacebraiding machine. The plates of the machine, shown in the left-hand part of that Figure are occupied by the bobbin-carriers 1, 2 3 4 5 6, 7 8 9 10 11 12 13, 14 15 and 16 one part of said carriers having bobbins with heavily tensioned threads on it, another part carrying bobbins with lightly tensioned threads. The former are marked by black points, the latter by small circles. The ways of the bobbin-carriers are shown in the right hand part of Fig. 2 by means of fine and bold strokes of the pen. In this part of the figure the spaces between the hori- Zontal auxiliary lines correspond to the plates, whereas the spaces between the vertical auxiliary lines correspond to one half revolution of the drivers. Those fine and bold strokes of the pen which run diag onally mean either movements of the respective bobbin-carriers on one and the same plate, i. e. twisting of threads, or transfers of the carriers from one plate to another, i. e. interchange of bobbins between adjacent plates. Finally, the strokes of the pen running co-dircctionally with the horizontal auxiliary lines mean arrest of the respective bobbin-carriers. As is evident from an inspection of Fig. 2 only a comparatively few stand-stills of the bobbin-carriers occur, therefore the work is rapid and economical.

In Fig. 3 an alternative form of our new lace-ground is illustrated. In this example, the diagonal threads 17, 20, 21, 24, 25, 28, 29 and 32 forming the wide-meshed net for connecting the longitudinal strips f, g, 72,, i are not only crossed within said strips, but are also (at B, B) crossed in the middle of the spaces between each pair of adjacent strips. By this means a lace may be produced which, although containing merely one and a half times as many threads as the lace shown in Fig. 1; is twice as broad as the latter. Consequently, when making the lace ground according to Fig. 3, the quantity of threads necessary for producing a lace of great width is still more reduced than with the ground-work of Fig. 1. The required braiding machine may also be a smaller one. Of course, to the laceground shown in Fig. 3 also tuft, leaflets, spiders or other patterns producible on the singlethread lace-braiding machine may be applied.

lVe wish to state that our invention not restricted to the examples shown and described. On the contrary many other embodiments may suggest themselves to those skilledin the art without departing from the spirit of our invention as pointed out in the following claims.

Claims:

1. A braided lace of the character set forth, having triangular meshes, which is composed of spaced warp pillars, each consisting of but two threads, twisted together, and a net work of rhombic meshes, consisting of single threads running diagonally across the warp pillars, said diagonal threads crossing each other within the warp pillars and being braidedly interlocked with the latter at the crossing points- 2. A braided lace having triangular and rhombic meshes which comprises spaced warp pillars, each pillar consisting of but two threads, twisted together, and a net work of rhombic meshes, consisting of single threads running diagonally across the warp pillars, said diagonal threads cross ing each other within the warp pillars and also in the spaces between the latter and braidedly interlocked with the warp threads at the respective crossing points.

In testimony whereof we aflix our signatures in presence of two witnesses.
