1 '0 all whom it may concern: I

Be it known that we, EMIL BENTE and PAUL STUHLMANN, citizens of the German Empire, residing at Barmen, Germany, have invented certain new and useful Improvements in Laces with Net or Tulle-Like Groundwork, of which the following is a specification.

This invention relates to the production of lace with tulle-like ground work. The object of the invention is to make the manufacture more simple, rapid and economical and to obtain with a very small number of threads a pleasant looking and firmly braid ed lace which retains its design and will resist distortion. With this and other objects in view, the present method of producing lace with tulle-like ground work consists in warp-like spaced pillars of but two threads, each pillar consisting of a lightly tensioned thread and a second more heavily tensioned thread, both twisted together, to form the pillar, and in connecting said spaced pillars by reciprocatively interchanging the lighter tensioned threads of the pillars soas to form pairs of transversal bars, and by crossing each transversa-l bar over the other so as to interlock with the heavier tensioned threads of the warp-pillars.

In the modification of this method the transversal bars are crossed over each other at different places the crossing points being located in the warp-pillars proper, and the other crossing points being in the space between twoadjacent pillars.

On making our new lace on the singlethread lace braiding machine the bobbincarriers of the latter are almost continuously in motion; especially during the producing of the ground-work only a few bobbin-carriers are to be arrested for short intervals, the working is therefore rapid and economical. Furthermore our new lace requires only a small quantity of threads; and as even the tension of those threads which are somewhat more heavily tensioned than others, is :still rather slight, the newv lace can be manufactured from'compa'ratively weak and consequently cheap thread material.

We now proceed to more fully explain our new lace and the process of making the same, reference being made to I the annexed drawing illustrating by way of example two show In Fig. 1 a scale;

ASSIGNORS TO MAX piece of lace on a greatly enlarged v Fig. 2 the ways of thebobbins in rodticg mg the lace illustrated in Fig. 1 onthe sin- Fig. 3 a piece of a second lace, also on a greatly enlarged scale In the example shown in Fig. 1, the

ground-work of the lace iscomposed of-a series of warp-like longitudinal strips 1 to 8, each strip being formed by twisting to 'gether a slightly tensioned thread a and a somewhat more heavily tensioned thread. 6. 1

For clearness the slightly tensioned threads" are marked by fine strokes of the pen, the

heavily tensioned threads, on the contrary, by bold strokes. The strips or pillars 1 to 8 are connected by means of weftliketrans versal staves orbars a, which are formed by interchanging the slightly tensioned threads a, a of two adjacent longitudinal strips and simultaneously crossing said threads; To

lockthe stave-s or spokes in their correct po sitions, the crossing points of the interchanged threads a, a are embraced by the heavily tensioned thread 6 of one of the two adjacent strips'and therebydra n into (the respective longitudinal strip. pair of threads a, a at the place of exchange Thus each resembles a loop formed by one thread-only,

but in fact' eachstave or spoke consists of two threads." From this a great durability of the lace results. Should any of the threads forming a stave orspoke 6 break, the longitudinal strips are 'st illmaintained in their correct distance by the aid of the re- I maining thread. In consequence of the fact that every following exchange of the slightly tensioned threads takes placebetween another pair oflongitudinal. strips than the proceeding one, the threads '66, a have a stepped run alternately in the one diagonal direction and in the other from one edge 'of the lace to the opposite edge and vice versa. Therefore, all threads a,a extend notfonly over the entirelength, but also over the en tire width of the lace, as a result of which the firmness and durability of the lace is once more considerably increased.

To make the ground-work illustrated in Fig. 1 on the single-thread lace-braiding machine, the bobbin-carriers a b are ar- (ill - slightly tensioned thread a which is ranged on the plates of the machine in such a. manner that each carrler a carrying a bobbin with heavily tensioned thread is followed by a carrier b having a bobbin with slightly tensioned thread on it. See lefthand part of Fig. 2 in which the first named bobbin carriers are marked by black points, the last named, on the contrary, by small circles. The ways of the bobbin-carriers are shown in the right-hand part of Fig. 2, wherein the spaces between the straight horizontal auxiliary lines correspond to the plat Whereas the spaces between the straight Vertical auxiliary lines each correspond to one half revolution of the drivers. The diagonal fine, and bold strokes of th pen illustrate the movements of the. respective bobbin-carriers on one and the, same plate or their transfer from. one plate to another, while the horizontal line and bold s r ke mean @t s tihs of th respec bobbin-carriers. As is evident from an in: sp ecti'on of Fig. 2, the bobbin carriers, are almost continuously in motion only during the interchange of the slightly tensioned threads v between adj acent longitudinal strips some those bobbin-carriers carrying a bobbin heavily. tensioned thread are rr t d o a or ms.

Of course, also to this lace spiders, tufts, leaf-like figures and other patterns usual in the hand-made lace and producible on the single-thread lacebraid; ing machine may be applied.

Finally the lace shown in Fig. 3 is provided with strengthened edges. These, edgesare formed by a continuous interchangeof the threads a, a between the longitudinal strips 1'. and 2 and 7' and 8 respectively, and by crossing said threads in the space be; tween the adjacent strips, while the latter are simultaneously drawn togetherso tightly as, to; resemble in thefinishe'd fabric a com;- mon' longitudinal strip. At the same time, there may, be produced some sort-of pi -cots at the edges of the lace by leading some of the slightly tensioned threads a, a out from the marginal strips and back into the latter so as to, form the loops m, m.

We wish it to be stated that our inyention is not limited to theexampleszshow-n: on the drawings, for many other embodiments may suggest themselves to those skilled in the art, without departing from the spirit of the invention as pointedout in. the fol lowing claims.
