Referring to the drawings, let A indicate the bed-plate of a loom; U, the driving-shaft; R, the pattern mechanism; G, the spindles; z, the finished fabric, and Z the take-off therefor.

As is well known, in the usual braiding-machines or looms having circular fran1es First. The threads are wound on bobbins arranged vertically upon tubular spindles, on issuing from which the threads are united at the center of the frame, forming, together, a more or less sharp cone.

Secondly. The spindles are subject to interrupted movements in circular guideways communicating with each other at their points of contact. 1

Thirdly. The movements of the spindles are obtained by means of disks having at their peripheries two or four diametrically opposite notches and revolvingconcentrically with the guideways and in contrary directions in pairs. The arrangement with two diametrically opposite notches will alone be considered here.

Fourthly. During a semirevolut-ion of the disks the spindles are only subject to the motion of the disks turning in the same direction, by which they are moved pasteach other for producing the crossings of threads, and they are then moved by the disks turningin the other direction for crossing their threads with those of the next spindles, so that half the spindles move around the frameone way and the rest the other way. On the completion of this semirevolution-that is to say, when all the spindles are arranged in line at the points of contact of the disksthey leave the first disk and follow for another semirevolution the motion of the disks traveling in the contrary direction, so that by this means the direction of the crossings of the threads is changed at each semirevolution.

Fifthly. The guidance of the spindles at the crossing-points of the guideways is obtained in most frames by means of articulated switches which open those guideways through which the spindles are to pass and simultaneously close the others.

Sixthly. The movements of the switches are alternating and in the opposite direction for two consecutive semirevolutions of the disks.

The resultingbraid in such machines has of course been of exact regularity in the crossings of its threads.

Referring now to Figs. 1 to 3 inclusive, I will describe the nature of the fabric I desire to produce. Ifa plaited band and a strip of lace be compared, it will be seen that there is considerable analogy in the modes of interlacement of the threads constituting the same, and it may be said that a piece of lace is a plait of which a certain number of interlacements have been suppressed according to a method adapted to each design of lace, as

shown at Figs. 1, 1 2, 2 3, and 3 of the drawings,which show, to an exaggerated scale, Figs. 1 and 2,1ace fabrics; Fig. 3, aportion of woven fabric, and Figs. 1, 2 and 3 the diagramsin which the thicklines indicate the order of the crossings of the threads, while the fine lines show those which are suppressed.

The order of crossing of the threads is well characterized by the fact that there are only produced at the same time crossings in the same directionthat is to say, that the whole of the threads being supposed to be divided into groups of two threads at the first line of the diagrams, all the threads passing from left to right pass below the threads passing from right to left in each group. At the second line the same process takes place, but in the reverse sense-that is to say, it is the threads passing from right to left which pass underneath those passing from left to right and the order of grouping of the threads is reversed. On examining Figs. 1 and 2 it will be seen, in effect, that a thread situated below the position 0 for example, is the lefthand thread of the group which it forms with the thread situated below the position 02 for the first line of crossings, and that for the second line the thread below the position a is the right-hand thread of the group which it forms with the thread below the position b. At the third line the process is the same as at the first line, and at the fourth the same as at the second, and so on. The result of these reversals at each line of crossings is to produce interlacin gs of which each thread passes alternately above and below those which it meets, whether for forming a plait or an element of lace.

From what has been said it will be seen that for producing lace or a like fabric it will suffice to prevent certain crossings of the threads, or, what is the same thing, to produce in any suitable order only a certain number of the crossings which would constitute a plait if they were entirely carried out.

It may happen that all the threads or only some of them effect more crossings in one direction than in the opposite direction. This would have for result to increase or decrease the degree of torsion of the threads. In order to remedy this inconvenience, the bobbinspindles must be prevented from turning on their own axis. The interlacings of the threads being obtained they must be tightened one against the other, as in any woven fabric, and the lace must be fed forward as it is produced.

I have invented means whereby a machine operating on the principle of a circular loom or braiding-machine can be utilized for making lace and other textiles of varying weave, providing means whereby the spindles can be controlled to obtain any desired variation or irregularity of the crossings of the threads, and whereby pattern mechanism can be employed to automatically control the operation of such machines.

IIO

1 will now proceed to describe, with reference to Figs. 4 to 35 of the accompanying drawings, how I realize the practical carrying out of the method of manufacture by means of the lace-frame invented by me. The general arrangement of the machine is the same as that of frames used for the manufacture of plaits or braid. It is composed of a foundation-plate A, resting on feet on which are fixed tubular axes a, arranged according to a suitable division for forming a circle, or, more correctly, a regular polygon. On each of the axes a is mounted a carrying-disk or flanged sleeve B, formed in one with a toothed wheel 0, situated below. All the toothed wheels 0 gear with each other. They are driven by one, or preferably by four, toothed wheels 0 C, Fig. 5. The sleeve-disks B are of such a diameter as to nearly touch each other. They are each provided with two semicircular notches b b, diametrically opposite each other and so arranged that the notches of two contiguous plates when passing through the points of contact form a circular hole as regular as possible. At the upper end of the axes a and'slightly above the disk B are fixed disks D, which do not. touch tangentially,as the disks B, butleave between them a space more or less equal to the diameter of the circular holes formed by the notches of two contiguous disks, as shown at Fig. 7. These disks D are surmounted by cross-heads E, Fig. 7, having in plan'a lozengeshaped appearance the large axis of which is about equal in length to the diameter of the disks D. The disks D and the cross-heads E are rigidly connected together by shoulders c, the thickness of which determines the distance between them. (See Figs. 17, 21, and 22.) In the same plane as the disks D and supported by columns Z from the plate A are placed two rings F F of the same thickness as the disks D and formed, the one internally and the other externally, with curved profiles concentric with the said disks D and so as to leave between them and the disks the same space asthat which exists between two contiguous disks. There are consequently formed sharp projections w 00, projecting toward the points of contact of the disks B. The one-half of these projections-namely,

those marked oc-are considerably blunted,

so that facing one sharp projection 50 of the internal ring F there is a blunt point 00 of the outer ring F, and vice versa. The circular spaces existing around the disks D are the paths or guideways, which serve to direct the spindles G, of which the foot H, Figs. 7 and 8, forms the characteristic part, the upper part being indifierently made of the one or the other of the arrangements ordinarily employed for facilitating a suitable unwinding of the threads and to give them always the same tension in the various positions which they may occupy in the machine. The feet H are formed of a cylindrical stem d, Fig. 8, carrying at about the middle of its length two large flanges e c. terminates at the upper end in the thick part II for carrying the tubular spindle G and a diamond-shaped flange f, carrying at each end a small stud g g. If the stems d of the feet be introduced into the circular paths,

the flanges e of the feet will embrace the disks D and the rings F F, which will prevent them from moving up or down, and the lower part of the stem (1 will penetrate into the semicircular notches b of the disks B, so as to receive therefrom the circular motion which is imparted to them in a continuous manner. The whole of the spindles thus set in motion will form a plait by the interlacings of the threads which result from such motion; but, as has been previously'stated, all the spindles must not circulate simultaneously for producing a fabric constitutinglace of any kind. A certain number of the spindles must consequently be prevented in a suitable order from being acted upon by the disks,or,which is the same thing, only those spindles must be submitted to the action of the disks which are required to circulate for producing a particular design of lace. 'For this purpose there are arranged below the blunted projections :10 plates I, mounted on stems 72, which are vertically movable and are guided on the one hand by the rings F F and on the other hand by the foundation-plate A, through which-they pass.

Helical springs 7; (see Figs. 6 and 8) raise these plates I and maintain them in a raised position when the downward-pulling action of the pulls J ceases.

For'preventing all oscillating motion of the plates I they are maintained by stems 1 fixed below-at the edges of the rings F F and which penetrate into grooves formed at one of the ends of the plates. At their other extremity, toward the point of contact of the disks and on their upper faces, the plates I carry a sort of ribj, having an internal profile of a very open V shape and the sides of which are parallel to the sides of the blunted projections 21; of the rings F F. These ribs pass sulficiently under the disks B to cause the lower extremity of the stem (1 of the foot of the spindle to come in contact therewith if they are raised and to slide along the sides of the This stem 61' V-rib, as on inclined planes. This sliding has the effect of disengaging the stems (Z from the notches b of the disks B and to bring them to rest in a sort of resting-place formed by the hollow space between the blunted edges of the rings and the bottom of the V-ribsj. (See Fig. 15.) The said spindles remain at rest as long as the plates I are not lowered.

The lowering of the plates I not only has for its object to free the stopped spindles, but also to force them to leave their resting-place at a suitable moment for rentering the notches of the disks B. This result is obtained by a system composed of two parallel bars is Z, connected together by a link m, Figs. 8, 12, 13, 17, 25, and 26, and arranged to slide between a disk B and its toothed Wheel 0. The lower bars carry a stud n, and the upper bars are flush with the back part of the notches of the disks B, so that if they are drawn out beyond the disks B, which cover them, they can project beyond the disk as an extension to the wall of the notch and will in their rotary motion reach the stems d of the feet, Fig. 13, and thus oblige them to recommence their motion in the manner shown in Fig. 39. For withdrawing from the disks B the bars 70 Z the movable plates I carry on their under faces and at their lateral extremities two ribsj, constitutinga cam, so arranged that if they are lowered their outer extremities force the studs 12 of the lower bars 7.: to slide on their profile, and thus cause the bars Zto pass outward in order to seize, in their rotary motion with the disks, the feet of the spindle-carriers which are required to be set in motion again. It is to be observed that for setting in motion a stopped spindle the lowering of a plate I acts simultaneously upon a system of bars l0 Z of each of the disks B, situated at the right hand and left hand of the resting-place. This simultaneous action has for its result to cause the two forces to act together for imparting to the foot (1 the direction which it has to follow for passing through the point of contact of the disks B, as at Figs. 13 and 89.

When the bars of the two contiguous disks are nearly touching each other behind the foot which they push, the cams j cease to draw the said bars outward. These cams are so arranged as to allow the said bars to reenter under the action of their respective thrusts against the like bars of the adjacent disk as they strike each other while pushing out a spindle. They then stay in until again pulled out by the plate I, which occurs so long as a plate is down. Each plate I is held down until a spindle is to be stopped.

It is to be remarked that the lowering of the plates I therefore not only has to be effected for setting in motion a stopped spindle, but also for preventing the stoppage of the spindles when they should continue in motion. In this case the movable bars 70 Zof the disks operate as above described, and instead of having to set in motion again a stopped spindle they operate, together with the notches b of the disk B, to insure its continued movement at the moment when it passes through the resting-place. \Vhile the plate I is down, the bars are drawn out by it as they pass and pushed in as they strike each other. When the plate is up, they are pushed in as they approach it by their cams o striking the edge of the plate, and thus are prevented from grasping a spindle when it is stopped on a plate.

From what has been said it will be seen that each system of movable bars is brought back under its disk at the moment of its passage through the points of contact of the disks and that it will only be made to issue again by the lowering of the plate I. I have, however, foreseen that it might issue without this lowering of the plates by an accidental cause--such, for example, as the action of a shock resulting from the sudden stopping of the entire machine. It is necessary in this case that the bars should be forced to reenter before coming in contact with the foot of the spindle when at rest, which they could not carry with them, because it is retained by the upper rib of the plate I. This is effected by a boss with incline 0 on the rigid connection in, between the bars, Fig. 12, situated below the upper bar Z, and consequently situated in the same horizontal plane as the upper ribj of the plates I, (see Figs. 8, 12, 13, 25, and 26,) which rib pushes away at the required time this boss 0 and the bars k Z, to which it is connected, as shown at Figs. 8, 12, and 39.

The guidance of the feet at into one path or the other at the moment of arriving at the points of communication is determined by the position occupied by the directing-switches K, Fig. 7, closing the one path and opening the other. These switches K are situated above the sharp projections an of the rings F F, opposite the resting-places j, and in the plane of the cross-heads E E, which serve as abutments to them. They are pivoted at the middle of their length and their position is changed at each semirotation of the disks B. At the same time that they open and close the path for the feet they operate, together with the slotted levers L,cross-h eads E,and the external inclines of the pieces M, to prevent the spindles from turning on their own axes in acting successively upon the studs g, fixed at the extremities and below the oblong flanges f of the feet. The pieces M are mounted on plates fixed to the top of the rings F F, above the flanges e of the spindles. (See Figs. 8 and 30 to 33.) For understanding the working of these several parts it must be borne in mind, first, that they are all situated in the same horizontal plane; secondly, that the cross-heads E and pieces M are fixed, leaving between them and the rings F F a space sufficient for the free passage of the upper flanges e of the feet; thirdly, that the switches K receive a to-and-fro motion which they communicate to the levers L through the medium of the links N.

Assuming a spindle to be stopped in its resting-place j, one of the studs g is maintained between the two pieces M M, Figs. 7, 36, and 57, and the other stud g is advanced toward the switch K, which can oscillate in front of it without touching it. At the moment when the spindle should be set in motion the switch is at rest and the right-hand path, for example, is open. When leaving the resting-place, the foot has its rear stud maintained for a certain length of time between the pieces M M. When it leaves these,the front stud can come in contact with the side of the directing-switch, or the rear stud can possibly come in contact with the cross-head E on the left hand, the foot being capable of oscillating between these two extreme positions. When the'foot is sufficiently advanced toward the switch for the rear stud to be necessarily in contact therewith, the front stud engages in the channel formed by the lateral part of the switch and the extremity of the piece M, which faces it, and afterward it engages in the slot 19 of the lever L. It will now be seen that if at this moment the switch begins to move in the direction of the arrow it will transmit its movement to the slotted lever L, which then assumes a position in which it allows the stud which it has held to leave it and to slide on the incline of the piece M, it being under stood that during this movement of the switch the central stem of thefoot is carried in the path by the notch 19 of the actuating-disk B. The spindle has thus been held in its entire motion in a position about parallel to that which it occupied at its point of departure, and the torsion of the thread will not have experienced any alteration.

All the internal and external switches on a frame operate simultaneously. It is sufficient to actuate a certain number of them, which communicate their motion to the others by means of links 0, pivoted to the extremities of the switches. For actuating the first they are mounted on the ends of a vertical axis P, Figs. 7, 8, and 14, passing through the rings F F and taking into the foundation-plate A. Immediately above this plate A the axis car ries an arm q, Fig. 8, which has a small roller below the toothed wheels 0 of the disks B.

This roller is pushed alternately from one side.

to the other by means of cams Q Q, (see Figs. 37 and 39,) each mounted on one of two ad-- jacent axes a and turning with and fixed below the toothed wheels 0. certain dwell is arranged between each movement, as shown at Fig. 14. A complete motion of the switches is obtained by a complete rotation of the cams Q, and consequently of the disks B. The other switches which receive the movement of the first by means of the links 0 are mounted on axes a, fixed on the rings F F.

It has been stated above that it is necessary to lower the plates I for effecting the putting in motion of the spindles or for the continuation of their motion, that this lowering is obtained by means of the pulls J that for producing the desired order of the interlacings of the threads it is necessary to put in motion those of the spindles whose threads are to cross and to arrest those whose threads should not cross. It will be seen that the two adjacent spindles, which are to be passed around each other by one disk, must be released and arrested at the same time in the construction shown and that if one of these isto pass that on its opposite side it must be held out for a half-revolution of the disk, so the switch can reverse, when it andthe one it is then to pass must be released. It results from this that as a plate I, carrying a restingplace of the outer ring, for example, must be lowered at the same time as one of its neighboring plates to the right and to the left alternately of the inner ring F, all the stems h of the plates I have two pulls J, connected with two levers 8 side by side and independent of each other, Figs. Land 8. One of these levers 8 serves to form the grouping of the stoppages considered relatively to its righthand neighbor, and the other lever s with its left-hand neighbor, as shown at Figs 4 and 5. The levers 8 form by their extremities s a face more or less serrated, the outer extremity of each lever -that is, the end under the machinebeing situated under the axis of the gear-wheel O for moving the disk B above the end of the lever for the posts h adjacent to such disk in each instance. The gears G are represented in the diagram by their pitched lines. The diagram shows in plan, Fig. 5, the two cords J for each post 71. connected each totwo levers .3, separate and independent the one from the other, and two cords J rising from the end of each lever s, the one of these cords coming to the one post h, situated at the inner side of the gears, and the other cord J coming to the next post h, situated at the outer side of the circle of gears 0. Only one of the levers s is shown in Fig. 4. These levers sare of unequal length, but they are all pivoted in such a manner as to have the same proportion of leverage, so that the extremity to which the pulls are connected having a determined motion the other extremity 5* has the same amount of motion for all the levers. lever s is connected by a wire t to an elbowlever u, the vertical arm of which is actuated by the rollers 12 of the endless j acquard-chain R, as shown at Figs. 10 and 11. This chain travels over a driving-drum g. It will be understood that the position of the rollers of this counter causes, when the chain travels, the descent of the pulls J, and consequently of the plates I, which have to effect the putting in motion of the spindles that have to work.-

The lace is formed as a tube, being formed upon a mandrel 2, Figs. 4 and 9. Supple mental threads 2 serve to unite the selvage or top and bottom edges of the lace for giving it a tubular form, this connecting-thread being afterward removed to allow the lace to be flattened out. These connecting-threads are shown dotted in Fig. 9. Each has aspindie and is controlled just as described for the other threads. These threads 2 may be con trolled by the pattern mechanism to cross first with the adjacent threads on one side, then with each other, and then with those on the other side, or they may be interlaced with the adjacent threads or any of them in any desired or suitable manner for fastening the edgesof the lace together temporarily.

The tightening of the lace produced'at X This extremity 3* of each is effected by means of beaters 7), divided into two groups and operating alternately in order that the lace may never be let go of and in order that the crossing of the threads that has been effected cannot come undone again. The heaters b are all pivoted on the upper end of a post 1, and every second beater is connected bya link 2 to a rising collar 8, while the intervening heaters are connected by links 4 to a rising collar 5, as seen in Fig. 4. The collar 3 has a neck surrounding the post 1, which neck is lettered 6, and the collar 5 has a neck 7 surrounding the neck 6. The collars are oppositely reciprocated vertically by a groove-cam 8, mounted on and rotating with the central shaft X, the collar 3 having a downwardly projecting arm 0, carrying a roller 10, engaging the groove in the cam, and the collar 5having a like arm 11 andlike roller 12 diametrically opposite the arm 9. As the cam revolves the rollers ride up and down in the groove, thus alternately raising and lowering each collar. The motion of each collar is transmitted to its series of beaters through its links. Thus half the heaters are swinging toward the anvil or mandrel while the other half are moving away therefrom. As the manufacture of the lace proceeds it advances on the mandrel z, fixed at its lower end upon the stem Y, placed at the center of the circular opening formed by the heaters I). The mandrel is first circular at the base and is gradually flattened until at the upper end at 2' it assumes the shape of a blade, over which the lace is drawn. For insuring the travel the flattened mandrel z is held between two rough carrier-cylinders c 0 which cause sufficient friction for insuring the regular travel of the lace. This issues at Z and is coiled upon a drum in the ordinary manner. Fig. 9 represents in its actualnature a piece of lace surrounding the mandrel on which it is formed, whereas Figs. 1, 2, and 3 represent in a very exaggerated scale some elements of the same lace. Fig. 1, for example, represents four tresses of threads of four threads each, connected the one tress to the other tress at points and more or less interwoven. The same thing is represented on the right in Fig. 9, with the difference that the tresses are represented by single straight lines crossing at their point of junction.

The machine receives its motion by means of a pulley T on the main shaft U, to which it is connected by a clutch. The shaft U transmits the motion through bevel-pinions (Z d to a horizontal shaft V, which actuates the parallel shaft V, Fig. 5, through the medium of the shaft V and pinions c e e c. The shaft V actuates at its middle the cen tral vertical axis X, which operates the beaters. The shafts V V impart motion through the pinions ff f f"f f"f f to the four toothed wheels 0, which actuate the wheels 0 of the disks B. The shaft V has at its one end aworm g, which actuates a worm-wheel g fixed on the shaft h of the counter y.

It will be seen that my invention provides improvements in the method of and in apparatus for manufacturing lace and other fabrics which can be advantageously availed of, and it will be understood that the invention is not limited to the particular details of construction, arrangement, or character of the apparatus, nor to the precise combination of features hereinbefore set forth as constituting the preferred form of my invention, but that it can be availed of in whole or in part, according to such modifications of construction, arrangement, or combination for such purposes and in connection with such suitable apparatus as circumstances or the judgment of those skilled in the art may dictate without departing from the spirit of the invention.

It will be seen that my invention provides means whereby a loom of the class known as braiding-machines (in which there are two circuitous guideways crossing each other at successive points, spindles traveling in opposite directions therein, and continuously-operating driving mechanism propelling the spindles) can be used to manufacture fabrics in which there is not a continuous regularity of crossings of the threads and in which these crossings can be varied automatically from time to time to produce the desired pattern or changes in the grouping and crossing of the threads. It will be understood that this is accomplished by the means I provide for disengaging or freeing certain of the spindles from the driving mechanism, so that while the crossing of other threads proceeds the threads of these spindles are not crossed. The plates I serve as the arresting mechanism by the engagement of their flangej with the spindles. By operating this mechanism from a pattern mechanism any desired pattern can be produced. I also provide means for insuring the restoration of inactive spindles to engagement with the driving mechanism. The barsl it, operated by the flanges j, are employed for this mechanism. Thus by arresting any group of spindles the loom can continue to twist the threads of the other, and by arresting and releasing spindles according to the position of the switches the direction of travel of the spindles can be controlled, so that, if desired, two adjacent spindles can be caused to travel continuously around the same driving-disk for twisting their threads on each other for a certain time, and then they can be separated and each pass to an adjacent disk for twisting with other spindles. For example, should the pulls J be If these spindles were held IIO out of the disk for a half-revolution, the switches would by that time have reversed in position, so that upon releasing the spindles and letting them again engage with thedisk they would be carried aroundwith each other ahalf-revolution. If they are to make another twist, they should be arrested at the end of this movement and held out for another halfrevolution to enable the switches to again reach the position for guiding them again around the disk. If they are to be separated, so that each shall engage another spindle, they would not be arrested at the end of the half-revolution, but would be carried past the switches, which, having reversed during the half-revolution, would direct them to the adjacent disks respectively. With the construction shown, therefore, it will be seen that the spindles are controlled by arresting or re leasing them, according to the position of the switches. It will also be seen that any desired grouping of the spindles can be accomplished and that any desired pattern can be produced.
