To all whmn it flea/y concern:

Be it known that I, JEAN KAPPELER, mechanician, a citizen of the Swiss Republic, residing at Mellingen, Canton Aargau, Switzerland, have invented new and useful Improvements in Braiding-Machines, of which the following is a complete, clear, and exact specification.

The present invention refers to braidingmachines in which the bobbins are carried by means of rotating plates included in the heads of the machine.

One improvement relates to the bobbinguiding arrangement; and it consists in the use for the conducting of the bobbin of an automatic coupling by means of which the same can alternately be connected to one or other of the rotating plates, whereby the conditions for working the machine are much more favorable and sure. A reciprocal reversing of the bobbin-coupling in the manner necessary for the guiding of the bobbin according to the pattern required is brought about in the course of the movement of the bobbin by a pattern mechanism, (preferably including one or more changing-pins, which are arranged in the heads of the machine,) such mechanism allowing of changing the course of the bobbins acZ Zt'Mt am.

A further improvement consists in the use of a mechanical contrivance by which the tension of the bobbin-threads may be easily and v quickly regulated.

The annexed drawings illustrate a mode of carrying out the invention.

Figure 1 represents an elevation of a braiding-machine with my improvements applied thereto. Fig. 2 is an elevation, partly in section, and Fig. 3 a plan view, of two machineheads in combination with a single bobbincarrier without spool. Fig. 4 shows the bobbincarrier by itself with hollow spindle without spool, whereby the spindle is partially given in section. Figs. 5 to 15 refer to cletails hereinafter mentioned and are shown on a larger scale than the preceding figures. Among these Figs. 6, 10, 11, 12, 14, and 15 are horizontal sections taken, respectively, through the correspondingly-numbered dotted lines shown on Fig. 5, that shown in Fig. 1 1 being viewed from below. Fig. 16 serves for explaining the modes operand i of the bobbin arrangement.

A, Fig. 1, is the table or top plate of the machine abovewhich the bobbins B, supported on hollow spindles 6, move in a serpentine manner through the machine-heads, in whose centers there are fixed vertical rods C in order to produce a braid which is drawn off by the take-up roller D and wound onto the reel E. The bobbins are carried round by means of rotating plates F, arranged in the machine-heads, which receive the bobbin-carriers in notches provided at their circumferences, and which, with the supplementary plates F, (insuring the stability of the bobbins,) are fixed on sockets 0, turning on rods G, and caused to simultaneously revolve by means of toothed wheels (0 and the chain-gear OZ by means of a hand-crank (a.

The general action of this braiding-machine is sufficiently well known, and it is therefore not necessary to enter into further details respecting the same. For the braiding arrangement, properly speaking, which represents the essential part of the invention and conducts the bobbins in their requisite path, reference is made to Figs. 2 to 4 with detail views, with the observation that the description of details following only treats of one bobbin; but it applies equally to all bobbins of the machine.

Spindle I) of the bobbin-carrier fits in a case G, on which is arranged a ring or socket mem her 9, provided with two flanges which overlap the edges of one or other of the plates F (both of them at the point of contact) above and below when situated in the notches of the plates. The upper flange of this ring 7 has two oppositely-lying openings for the passage of two balls 71,, which have the function of temporarily coupling the rings 7 of the respective bobbin-carriers alternately with the one or other of the plates F. Every plate F is provided behind each notch with a ball hole or hollow f, while there is mounted above the ring g a rotatable slide 72/, turning round the case Gr, which at its lower side is cut out at 7L2, Figs. 5 and 14. These parts (ring 9 with balls it and rotatable slide 72/) form, in conjunction with the hollows f of the plates F, an automatic coupling in form of a doubleball fasteningbetween the bobbin-carrier and the plates, inasmuch as normally one of the balls it lies in a hollow f of the one plate F and by means of the rotatable slide 71 is prevented from rising, Fig. 5, while the other ball can reenter unhindered the corresponding cutting 72. of the slide when the bobbincarrier in the conducting-plate F comes into the reach of the plate next following and the free ball is made to run on its upper surface.

The rotatable slide it carries a curved engaging lever 2', Figs. 3, 15, and 16, which is pivoted at 2 and by means of which the slide 72' can be turned from one end position, in which it fastens one ball and releases the other. to the other end position, in which it by an opposite movement fastens the latter and releases the first. ments shall take place automatically, there are provided in the heads of the machine on plates K adjustable projections k, Figs. 2 and 3, which are at the same height as the curved lever 2' and which at each movement of the bobbin can produce the change in the one or other sense, according as the curved lever2' comes with one or the other end into the sphere of action of one or the other of the projections 72', as will be more fully explained hereinafter. In order to bring the curved lever 2' out of the reach of one of the projections K? into that of the other, there is provided a ring m of angular cross-section, Figs. 5 and 13, whose vertical side is engaged by the ends of the lever 22', Fig. 15, and which is guided to move in a straight line by means of two guiding-rails m, engaging two recesses in the case G, Figs. 5 and 12, and the displacement of the ring 222 into an eccentric position in the one or other direction results in the lever 2' being turned on its pivot, and one of its ends is brought nearer to the central axis of the case Gr and the other is removed from it, so that one end of said lever 2', which is represented in Fig. 15 in its center position, is removed so far from such middle axis that (as the bobbin is'moved past the proper point) it can engage one or the other projection Z9, and thus produce the angular displacement of the rotatable slide 72 The displacement of the ring 222 into eccentric position (which thus operated the coupling mechanism) is produced by means of a turnable controlling-collar O on the case G, (in Figs. 9, 10, and 11 represented separately) which is provided at its lower end with two flattened portions, Fig. 11, and fits between two pins 0 of the ring 272, Figs. 12 and 13, so that when the collar O is turned one or the other edge 0', Fig. 11, engages the corresponding pin 0 and pushes the same along, with the ring 272, sidewise, whereby the latter is guided in a straight line by means of the rails 222 and the lever2' is turned, as described. The collar O is held against upward movement by a collar 0, Figs. 4 and 5.

Outside of the controlling-collar O there is a stirrup P, which is adjustable on a vertically-movable rail 1) on the collar O and is adapted to be automatically brought into two different positions of height, the one in the sphere of action of changing-pins Q, which are centrally fixed in the heads of the machine, and the other out of the sphere of action of such pins. A spring Q, which is connected at one end to a projection on the rail p and at its In order that these move-- other end to a projection on the collar O, has a tendency to hold the rail p, with the stirrup P, in its highest position, in which the latter, by means of the upper end 1) of the rail 39, Figs. 5 and 9, lifts up a so-called disengager in form of a saddle-piece R, which is guided in its upward and downward movements by means of rod '1", lying in a vertical slot 2", Figs. 5 and 6, in the case G. This saddle-piece R, which is represented with its guiding-rod in Fig. 8 separately, has at its ends two beveled surfaces 2' and at its top a saddle r It has for its object to cooperate with a pattern-collar S, separately represented in Figs. 6 and 7. This collar has at its upper part a circular row of pins 8. by which means a turning movement step by step can be imparted to the collar, for which purpose (see Figs. 2 and 3) on one side of the righthand machine-head, at the same elevation as the circular pin-row s, a switch-pin S is provided, which at each revolution of the bobbin advances the pattern-collar S one pin .9 in this machine-head. It will be understood that the machine may have any suitable number of such switch-pins, which may be arranged upon several rods C, so as to cause the pattern-collar to be switched at different points on the bobbin course when the bobbin is running through all of the heads of the machine. The arrangement should be such that no one bobbin should interfere with the succeeding or preceding bobbin. On the lower end the pattern-collar S has at its circumference a circular row of openings 8. In some of these openings pins 8 are inserted, which are within the sphere of action of the saddle-piece B. When the collar S turns, one of the pins 8 engages one of the beveled surfaces '7 on the saddle-piece R and pushes the lattter down, (against the action of the spring q.) The pin is temporarily held fast in the saddle 2' and the rail p is depressed, thus placing the stirrup P of the controlling-collar O on a line with the changing-pin Q, so that the latter by engaging the stirrup P can turn the controlling-collar O, and thus by means of the ring m can bring the lever 2' into a position in which it is adapted (through the help of the projections to bring about an angular displacement of the slide 72, and through the described operation of the double-ball-coupling device of the bobbin-carrier to effect the passage of the same from one plate to another. This operation repeats itself as often as the saddle-piece R is pushed down by means of a pin a of the pattern-collar. When, however, at the turning of the pattern-collar S no pin 5' runs onto the saddle-piece, the latter is lifted and the stirrup P is withdrawn from the influence of the changing-pin Q. Therefore, according as the saddle-piece R is pressed down by means of a pin s of the collar S or not, there takes place a transference of the bobbin from one plate to the other, or the The collar S is formed with serrations s on its lower side, which are designed to engage a screw-stud r on the saddle-piece R, whereby to prevent too great a rotative movement of the collar as it is turned by the switch-pins S in case no pin 8 is in position to operate the stirrup P.

The working of the above-described arrangement is as follows: For this purpose let it be kept in mind that the bobbin-carrier proceeds successively through any two machine-heads, as shown in Fig. 3, in an approximately 8- like course. To explain this course of the bobbin-carrier more clearly, there are given several positions of its members in Fig. 16. Assume that the bobbin-carrier move from the point as, Fig. 3, of its course and be taken by the left plate F in the direction of the arrow Z. The ball 7b of the coupling lying next to the axis of this plate lies in the hollow f of the plate locked by the slide 7L, while the other ball lies free, Fig. 16, position After making an angle of about one hundred and twenty degrees the stirrup P, which by means of a pin .9 of the pattern-collar S, as seen at Fig. 4:, is held at the elevation of the changing-pins Q, pushes onto the changing-pin Q belonging to the left head, whereby the controlling-collar O is turned, Fig. 16, position II, and by means of the shifting of the ring m, brought about by the pins 0, reverses the position of the lever i out of the eccentric position indicated onFig. 16, 1'". into that of Fig. 3. In the further course of the bobbin movement the free unlocked ball/1. runs, so to speak, without friction on the plate F of the right-hand machine-head in Fig. 3 in order ultimately (when the bobbin arrives at the position indicated in Fig. 3) to fall into the hollow f of this plate. In the same moment the reversed lever pushes against the projection 7r of that head, Fig. 3, whereby the slide it is turned, locks the ball, which was until then free, and releases the other, Fig. 16, position III, so that the bobbin is uncoupled from the left plate, but is coupled. with the right one and is now carried farther on by the same. The lever 2', thereby carried along by the slide it, remains, as is evident, out of the reach of the projection 70, belonging to the left head, while the ring m still retains the previously-assigned eccentric position for the present, Fig. 16, position III. As soon, therefore, as the bobbin, now guided by means of the right plate, attains the position 2 Fig. 3, a pin 8 of the pattern-collar S touches the switch-pinS', Fig. 16, position 1V, so that the latter in the further progress advances the patterncollar S and again allows a pin .9 to engage the saddle-piece It while lowering the same. (It is assumed that two pins immediately follow each other on the pattern-collar.) The stirrup P thus remains in the lowest position and at last by engaging the changing-pin Q of the right machine-head an analogous process takes place, only that now the various parts are so operated that a disengagement of the bobbin-carrier from the right plate F and a coupling of the same with the left plate F takes place, and the bobbin, following the direction of the arrow Z, can again attain the point of departure. Starting from this point, the bobbin always takes the same course until a change in the switching takes place in the position y of the pattern-collar S. If this presents no pin 8 to the saddle-piece R, the saddle-piece it, along with the stirrup P, under tension of the spring 1 can ascend, which allows the stirrup P to pass above the changing-pin Q of the right machine-head. A reversal of the controlling-collar O and of the ring m, influencing the curved lever '17, does not take place, so that the latter maintains the position III. (Indicated inFig. 16.) The coupling of the bobbin-carrier with the right plate F is maintained, Fig. 16, position III, and the bobbin turns in a circle in the right machine-head, which continues until in the sequence of the switching of the patterncollar S a pin of the same again pushes,

down the saddle-piece R, and thereby again brings the stirrup P into the reach of the changing-pin Q of the right machine-head. According to the number of the pins s on the pattern-collar S and their respective arrangement the bobbin can be caused to move in periodically-returning sequences. For example, a course through both heads may be given to it, then a course through one head, and again a course through both heads, and afterward two courses through one head or one run through both heads, three runs through one head, and again a run through both heads, &c. These alterations are manifold and each of the same corresponds, as is evident, to a different braided pattern.

IVhat has here been said of two heads of the machine applies, evidently, to the whole series of them. Their number and arrangement depend upon the nature and design of the braid (or lace) to be obtained, as is the case in the known braiding-machines. It will therefore, for example, be possible to group a number of heads in a circle round a central head or arrange sidewise one or more additional heads with relation to a circular series of heads.

.In the braiding-machine represented in the drawings there is within the hollow bobbinspindle (see Figs. 2 and a) a pipe U, which carries at its upper part a tension-roller u and serves to keep taut the thread carried round it.

The pipe U isclosed at the bottom and contains a larger or smaller number of separate weights 0;, which by means of a side opening in the spindle b and another in the pipe U can be introduced or withdrawn from the same. A pin 10, which projects into a slot w of the spindle b, prevents the dropping out of the pipe U in case the thread breaks. It can be so far pushed back that it permits the taking of the pipe U out of the spindle 6 downward. This arrangement greatly simplifies the changing of the tension of the threads, as it is only necessary to insert less or more weights 9) into the pipe U.
