To @ZZ whom t may concern.-

Be it known that I, KARL NECKER, a sub- Ject of the King of Prussia and German Ernperor, and a resident of Berlin, in the Kingdom of Prussia. and German Empire, have lnvented certain new and useful Improvements in Machines for Sewing Beads to Fabrics, of which the following is a specification.

My lnvention hasl reference to a machine for sewing beads to fabrics, by attaching the beads drawn on to an overstitch thread, to the braid, or cord,fand then sewing the two together by means of a quilting stitch.

In order that the invention may be fully understood I will proceed to describe itwith reference to the accompanying drawings, in which similar letters are used to denote similar parts.

Figure lis the representation of an ordinary quilting stitch. Fig. 2 is the representation of a combined quilting and over stitch: F1g. 3 represents a braid with beads sewed on. FigA. to 1l are detail views showing the dlfferent stages in sewing the beads on the braid. Fig. 12 is a schematic front view of the machine. Fig. 13 is a front View of the machine. Fig. 14 is a plan of the same, the cover being omitted. Fig. l5 represents the actuating mechanism of the bead-thread-carrier. Figs. 16 to 18 are detail views. ,n

a is the braid or cord, b the needle thread, c, the shuttle thread and d the over stitch thread. As can be seen from Fig. 3, the beading thread is not laid over the braid, as heretofore, alternately, as an empty, and as a full thread, that is, at one time with beads and the next without, but is always used with beads drawn on. This is made possible by the following invention which comprises, first, a thread-carrier bringing the beading thread across the braid as may be necessary for ultimately sewing with the quilting stitch; second, a bead-holder which keeps the necessary beads arranged ready foreach row across the braid; third, a bead distributer which, at the right moment, guides the beads to the thread-carrier, and fourth; a bead-pusher which pushes the beads on that may have remained on the thread.

It is immaterial whether the above four devices be attached to' a longitudinal or a circular shuttle-machine.

In Figs. 4 to 1l are shown the various phases in the production of the beaded trimming.

The braid a lies on a disk A and a little to piercing the braid a. The thread-carrier e seizes the beading thread d on the right and carries it on the left over the-braid a.. Below the thread-carrier, are three beads on the Y thread, while the bead distributer f, f incloses three others. g is the bead-holder. Now,while the needle is piercing -the braid a (Fig. 5), the thread-carrier e, which hasv meanwhile passed over to the left, sinks, the lower part of the distributer f opens and three beads held by it fall on the top-of the thread-carrier e. The holder, g during these movements, keeps the beads on the right ready for the next stitch. The thread-carrier e now sinks farther (Fig. 6) and slightly forward so that it forms a loop on the left side through which the needle can pass. The holder g remains in its position, While the upper part of the distributer opens, so that a fresh supply of beads can be advanced. The l needle (Fig. 7) by piercing farther forms a loop through which the shuttle s with shuttle thread c can be driven. Meanwhile, threadcarrier e has left the loop and consequently the beading thread also, allowing the three beads to the left to slip down to the edge of the braid. The holder g has now receded, having released the beads held back, which are at once brought to the top of the braid a. The distributer f, f is now closed.` The needle now goes back and draws, in the well known manner, the shuttle thread into the braid, and the loop of the overstitch beading thread d is fast to the left side. (Fig. 8.) The thread-carrier e. seizes the same above the three beads on the left, passes with it to the right, and the bead holder g is again advanced, securing the beads in their position.

lThe needle has finally quite receded (Fig. 9),

thread-carrier e has sunk to the right and the formation of the loop of the beading-thread d commences after the under part of the distributer has left the three beads slip onto the thread-carrier e. After the thread-carrier e (Fig. 10) has completed the loop by downward and forward-motion (the disk A has in the meantime advanced one stitch) the IOO ciente needle again pierces through the braid, while the beadholder y still assures the position of the three beads on the left. The lower part f of the distributer has now closed, the upper part f opened and three fresh beads pass into the distributer. Finally, (Fig. 1l) threadcai'rier cleaves the loop on the right side free. The three beads resting on the top of said thread-carrier slip down to the right edge of the braid a, the holder g recedes and the tension on the beading thread not only draws the right thread up, but also brings the three beads, until then on the left of g, onto the surface of the braid a. The whole operation now commences again. (Fig. 4.)

It is clear from the description that the thread-carrier e makes a to and fro motion transversely over the braid a and an up and down motion and iinally a forward and back motion vertically. The holder g must likewise make a backward and forward motion horizontally. The distributer f, f must open at the top and at the ybottom alternately and close again. There is also the bead pusher for pushing the beads down which have ref mained on the thread from any cause whatever. This bead pusher has also an up and down motion.

Figs. l2 and 13, show a mechanism chosen for carrying out the above operations, Fig. 12 giving a schematic front view showing the advance of the beading thread and the winding off of the finished braid'. In the framing B is a cain seated on the driving spindle, for actuating the thread-carrier` e, the distributer f, f', bead-holder g and beadpusher` 'i'. The braid ci proceeds from the roller c provided with a brake device and is brought into the disk A from under the tension roller C. The groove on the disk for the reception of the braid is naturally chosen according to the width of the saine. The roller D, also provided with a brake device, contains the beading thread d, which is led over a spring roller D', and passes the distributer ff', bead-pusher i and thread-carrier e, when it is gripped by the lastnamed holder g, when the holder g holds it and comes into contact with the braid a, at m, in order to be sewed onto the same. The finished product passes off the disk A, to the winding roller E, being conducted thereto by the lower roller E', upper rollers E2 and E3; the tension roller E4 keeping the band taut. According to the greater or lesser contiguity of the rows of beads, is the disk A more or less advanced. Fig. 13 is a front View of the complete machine; Fig. 14, a plan of the same with the cover removed and with the omission of a few well-known details. Figs. 15 to 18 are details.

The movement of the thread-carriereis effected by the triple cam K, K' and K (Figs.

and on the other hand (K is a worm-disk bearing on pivot n) bears in the lever arm rotating at o, said arm being actuated by I and so giving the thread-carrier e, a to and fro motion transversely over the braid. The spring G tends to keep the arm Z close to K. The holder g is pushed downward and forward (Fig. 14) in the direction of the middle plane of disk A by means of the worm disk Z3.

The distributer (Figs. 13 to 18) consists of two shears f,f lying one over the other, the parts of which, rotating at r, are kept closed by the pressure of spring t. When their rear parts u u are pressed apart by the pusher 'v the parts j' or f' open. The lower part f bears in the fixed arm w', whilethe upper part f is attached to the slightly yielding iron w on fixed arm w. The iron w can be drawn on or removed from w by means of the micrometer screw y. By this means, one can regulate the space between f and f according to the number of beads required foreach row. The forward and backward motion of pushers i; and 'v' for the opening ofthe parts and f', is eected by two eccentrics Z, Z (Figs. 14v and 16.) o

The bead pusher i (Figs. 13 and 14) receives its up and down motion from the cam Z4.

It has still to be mentioned that the sewing needle receives its to and fro motion from the grooved cam F, (Fig. 14), while the shuttle s is driven by another such cam G. When a vertical motion of the shuttle is chosen as shown in the drawings. The choice of shuttle and its movements is immaterial. The machine can also be used with other ornamental threads, such as silks, chenille, dsc. For this purpose, the thread-carrier e is retained for holding the thread, while .the distributerf, f', holder g, and pusher i, are removed.

Having now described my invention, I declare that what I claim, and desire to secure by Letters Patent of the United States, is
