MACHINE FOR INSERTING THREADS INTO WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 549,737, dated November 12, 1895.

Application filed April 15, 1895.4 Serial No. 545,813. (No model.) I

To @ZZ whom it ymay concern: l

Be it known that I, EDMUND MORRIS, a citizen of the United States, residing at Michigan Oity, in the county of La Porte and State of Indiana, have invented certain new and useful Improvements in Machines for Inserting Threads into Woven Fabrics, of which the following i's a specification.

My invention relates particularly to ma-I chines for inserting threads or strands of canel diagonally into previously-formed open-mesh cane fabric composed of warp .and weft threads arranged in pairs. Such fabric with two sets of diagonal threads interwoven and arranged at right angles to each other is commonly used in the manufacture of the backs and seats of chairs and settees. Two types of machines have heretofore been Icommonly employed for this purpose: first, those employing a crossing-needle which is rotated and at the same time passed diagonally across the fabric, over the warps and under the wefts,l so as to open a diagonal channel from edge to edge of the fabric for the shaft of the needle, into which channel a cane-thread is drawn when the needle is retracted; second, those employing dies or separators which act upon' the warp and weft threads in the fabric to bend them, and thus open a diagonal passage through which anon-rotary needle is reciprocated to lay an additional diagonal thread,

My Patents Nos. 534,343 and 534,344, dated February 19, 1895, show machines for inserting diagonal threads into cane-cloth differing from the two types of machines above nientioned; but as those machines have not been extensively used, they need be only thus referred to.

The machine forming the subject-matter of my present invention differs, essentially, in its mode of operation, as well as in its construction, from any of the machines above mentioned, and more nearly resembles in operation the old and more natural method of inserting the diagonal threads by hand.

I employ devices which pull each strand successively through each of the meshes in a diagonal row across the previously-formed fabric, over the warps and under the wefts, without bending or abrading the warps and wefts or putting themA under tension or in threads woven in the usual manner is led from a supply-roll at the rear end of the machine, over suitable guides and between devices for inserting the diagonal threads, to a take-up roll which is actuated to wind the completed fabric asA it is step by step advanced by the feeding devices. On each side of the horizontal plane of the fabric I arrangeja series of devices which I call pullers, that engage with threads supplied to them by threaders and interweave them with the warp and weft threads by pulling the additional threads over the warps and under the wefts and through the meshes in a diagonal direction across the fabric as it is step by step advanced. The pullers are in the form of hooks with pivoted jaws or latches that open and close at intervals to receive and release the threads, and the threaders are constructed to so manipulate the threads as to move them at proper times into the path of the hooks and effect their engagement therewith when the latches are open. The thread to be woven diagonally is drawn through a guide by a diagonally-arranged picker that lays the thread in a clamp called a pincher,

which as it closes severs the thread into proper lengths, and additional clamping devices are also employed for holding the diagonal threads after having been released by the pincher. While thus clamped, the threads are seized by the threaders and presented to the pullers that interweave them with the cloth, the free end of each thread growing shorterand shorter until it is finally entirely interwoven.

The accompanying drawings show my improvements embodied in lthe best way now known to me. Some of said improvements may, however, be used without the others IOO and in machines differing to some extent in their details of construction from that herein shown. Unless otherwise indieatefhthe parts are of usual approved construction. That end of the machine at which the take-up roll is arranged I call the front, the opposite the rear. That side of the machine to the right of one facing the front I call the right, the opposite the left Figure 1 shows a longitudinal section on the line 1 1 of Fig. 2 through a machine embodying my improvements.

Fig. .'30 shows a front elevation of the same. Fig. 31 is a detail view showing particularly the position of the thread when the threaders and pullers are in the position shown in Figs. 29 and 30.

The main frame for supporting all of the mechanism employed is shown as consisting of two upright similarly-formed parallel castings A A on opposite sides of the machine, iirmly connected together at their rear ends by plates c a and a bar a2 and at their front ends connected by a plate a3 and bar afl. The castings are formed, as shown in Fig. 1, with projections which extend upwardly above the pla-ne of the plates a CL3, each side casting being provided on its inner side with. a groove or raceway extending vertically from top to bottom of the frame and constituting guides for the transverse bars that carry the pullers, as will be hereinafter explained.

The main drivingshaft B carries a bell;- pulley l), extends transversely across the machine, and is journaled in bearings in the lower portion of the side castings AA. A spur-wheel b on the left-hand end of the main shaft B gears with a cog con the short shaft C, the cog c in turn gearing with a cog (l on a shaft D, which extends transversely across the machine and is journaled in bearings in the lower portion thereof. On the right-hand end of the shaft D there is an other cog d', which meshes with a cog c on a short shaft C. These shafts thus geared together are provided with means for actuating the mechanism hereinafter described for effecting the various operations incident to inserting additional threads into the fabric fed through the machine.

The open-mesh cane-cloth X, composed of warps a: and wefts 11;', arranged in pairs, as usual, is supplied from a roller E at the rear end of the machine, and it is led upwardly therefrom over supporl ing guide'rollcrs F F, and thence downwardly to a take-up roller G. The roller E is mounted on a square shaft e, supported at its left-hand end by the projecting tip of a short shaft c, journaled in a bracket c2 of the main frame, and at its right- IOC IIO

hand end by the projecting tip of the short shaft e3, j ournaled in a bracket e7, projecting rearwardly from the main frame.

In order to produce a suitable tension on the roll of cane-cloth, I secure to the shaft e an arm e4, which engages with a pin e5, projecting from an arm e on the shaft e3, at the outer end of which is a disk e8, which is rigidly secured to the shaft and has frictional contact with the smooth side of a ratchetwheel e9, loosely mounted on the shaft and engaged by a pawl e111, pivoted on a pin e11, fixed to the main frame. The pressure between the disk es and ratchet e may be regulated by a headed screw @12, adjustable in the end of the shaft c3. The guide-roller Fis mounted in bearings on two standards j', secured to the horizontal plate a, and the guide-roller F/ is mounted in bearings in standards f2, mounted on the plate as at the front end of the machine.

The take-up roll Gis mounted upon a square shaft g, supported upon projecting tips formed on the ends of a driving-shaft g and an opposite shaft g2. Upon that portion of the shaft g which is outside of the main frame I secure a friction-disk g3 and arrange alongside of it a ratchet-wheel g4. An arm g8 on the shaft g is provided with a pin gg, engaging with an arm g10 on the shaft g. The ratchet is revolved at intervals by means of a pawl g,pivoted to the upper end of a lever G2, rigidly secured to the shaft G'. This shaft is oscillated, as will be hereinafter described, and effects the rotation of the roller G step by step. The reverse movement of the roller G is prevented by a detent g7.

rlhe cloth is fed forward step by step by means of devices which alternately clamp and release the cloth and which have a longitudinal movement back and forth. On the crossplate a3 is mounted a frame-plate H, which is adapted to move back and forth longitudinally of the machine between guide-plates 7i. The plate H has secured to it at its rear end a transverse bar H', which extends laterally in both directions from the rear end of the plate I-I, and at opposite ends has upwardly-extending standards 7L', that are formed with guides for the upper and lower clamp-bars H2 H3, one of which is arranged above the cloth X and the other arranged below it. The lower clampbar H3 is pivotally connected on its lower side with two eccentric -straps h2, that extend around eccentrics h3 on a horizontal shaft h4, mounted in bearings in the lower endsof the uprights 7l. An arm h5 is rigidly secured to the shaft 7b4 and is connected bya rod 7L"` with the end of a lever 717, pivoted on the shaft GC rIhe lever h1 carries a roller 71.8, that enters a cam-groove 71,9 in a cam H9, mounted on the shaft D. As the shaft rotates, the lever 72,7 is

oscillated and an up-and-down movement is' given to the lower clamp-bar H3. The upper clamp-bar is normally stationary-that is, it is not reciprocated up and down, as is the lower clamp-bar-but it may be adj usted by means of cams 7L1-0 on a shaft H1, mounted in bearings in the uprights 7L above the clamp-bars. The shaft H4 is provided with a handle H5,by means of which the cams 7i10 may be turned to depress the upper clamp-bar, which, as shown, is provided with arms H6, through which the shaft H4 extends and which extend over the top of the cams 7z10 and bear upon them, the arrangement being such that by turning or adjusting the handle H5 the upper clamp-bar may be raised or lowered, as desired, and held in any adjusted position.

The frame-plate H is slotted longitudinally to permit the passage of the vertically-extending arm 71,11 of a bell-crank lever H1, which is loosely mounted on a shaft H3, that extends across the machine and is j ournaled in bearings in the frame thereof. The lower rearwardly-projecting portion of the bell-crank lever is slotted at 7i12 and is adjustably connected with a rod 7i13, the lower end of which is connected at 7L14 with a lever 7L15, rigidly secured to the shaft G. This lever 7L15 carries a roller 7L16, working in a cam H10 on the shaft D. On the front end of the plate H is secured a short standard 7L11,to which is pivotally connected an arm '7118, the rear end of which is provided with a laterally-projecting arm carrying a roller 7t19, extending into a curved slot h2o in the upper end of the bellcrank lever above the frame-plate H. As the bell-crank lever is oscillated by means of its connections with the lever 7%15, an oscillating back-and-forth movement is given to the plate H and consequently to the clamp-bars, the arrangement being such that the forward movement is effected after the clamp-bars are compressed upon the fabric X. Vhen the bars have reached the limit of their forward movement, the lower clamp-bar is lowered, thus releasing its grasp upon the fabric, and when the clamp-bars retreat the fabric is loose between them. At the end of the backward movement of the clamp-bars the devices are operated to again compress the clamps upon the fabric, so that on their forward movement they may draw the fabric forward another step.

`In order to vary the longitudinal or backand-forth movement of the clamp-bars while the machine is in operation to adjust the feed, I secure an arm 7121 to the shaft Hs and connect the arm b21 by a link h22 with the arm 71,18. On the outer end of the shaft H8, I secure an upright lever H11, provided with a detent 71,23, engaging a curved rack 7W, projecting from the frame of the machine. By this arrangement the shaft H8 may be turned in either direction and held, and by means of the link 7i,22 adjust the position of the roller 7i19 in the slot 712, thus varying the throw of the frame which carries the clamp-bars.

The mechanism for clamping and feeding forward the fabric is nicely adjusted and cooperates with the take-up mechanism, so that the fabric as fast as fed forward is wound up on the roller G, but is not pulled forward past the clamps by this roller.

It will be understood that it is of grea-t im portance that the step-by-step forward movement of the fabric should be accurately adjusted in order that the fabric may be fed one mesh at a time to receive the devices for inserting diagonal threads into them and in such manner that these devices will not abut against or abrade the warp and weft threads which bound the meshes. The feed mechanism which I have just described does the work accurately and may be nicely adjusted by the adjusting devices above referred to.

In order to prevent sidewise movement of the fabric, I provide two or more toothed wheels I, mounted on a shaft I', extending across the machine above the fabric and j ournaled in bearings in the side castings. These wheels I are free to revolve about the shaft l', and their lengthwise movement on the shaft is prevented by collars t on opposite sides of the wheels. The teeth t" of the wheels are accurately shaped and spaced so that they shall pass through the meshes of the fabric, the wheels being rotated bv the fabric itself as it is advanced.

The additional thread Y to be inserted is fed from any suitable source of su ppl y through a guide J, provided with a short springpressed pin j, from which a short end of the thread always projects. The guide J is arranged in line with a diagonally-arranged picker J', which may be of usual construction. As shown, it is constructed and operated as follows: A dovetailed slide-bar j', mounted on a standard' ji, rising from the frame-plate u., supportsa picker-block ji, carrying a horizontally-arranged rod j", at one end of which are secured spring-jaws j, operated by a block j() between them. The block j is secured to arodjf, adapted to reciprocate in the hollow rodj4 to move the block past the inwardly-curved portions js of the jaws into the enlarged portions ,7'9 thereof, thus quickly opening the jaws and allowing them to at once close. The rodj is operated at the end of the forward movement of the picker and also at the end of its backward movement by pins jm j, that project upwardly from the slide-bar] and alternately engage with a downwardly-projecting lugjl2 on the end of the rod jl. A reciprocating motion is imparted to the picker by a link jm, connected by a ball-and-socket jointjl* with the pickerblock, and in like manner connected at its opposite end to the end of an oscillating' lever j, secured to an upright shaft jl, which carries an arm j, connected by a link j18 with an eccentric-strapjl, encircling an eccentric )'20 on the main driving-shaft B. After the picker has moved forward and engaged with a thread at the guide J it retreats and lays the thread below the jaw 7c of a pincher K, which when it descends clamps the thread upon a block iV, and also moves it against a knife or cutter 7e', that sevei's the thread to be interwoven in the fabric from the remaining portion thereof. The jaw 7c is pivoted to a bracket k2, projecting from a frame-plate K', mounted on a cross-bar K5, and is operated by a rod K2, extendingdownwardly, embracing the driving-shaft B, and carrying a roller 7a, entering a groove in a cam K3 on the driving-shaft. A bar K onv the front edge of the plate K' under the fabric is employed to prevent the diagonal thread from twisting when acted on by the lower threader-plate. The additional thread to be interwoven is held by the pincher until taken by the devices which interweave it with the fabric, and which l will now proceed to describe.

A bar L, which I call the puller-carryin g bar, extends transversely across the machine above the fabric and is secu red to blocks L', mounted to move vertically in the guides or raeeways l, hereinbefore referred to. A similar puller-carrying bar L2 extends across the machine below the fabric X, and is likewise provided with guide-blocks L, which are adapted to reciprocate vertically in the raceways t. Upright rods l' are secured to the guide-blocks L' and L, rigidly connect them together, and cause them to reciprocate simu ltaneously in the same direction when they are actuated.

In order to give a vertical reciprocating movement to the puller-carryiilg bars, I secure to the short shafts C C' arms Z2, which are adapted to rotate around with the shafts, and which are joined at Z4 to pitman-rods L4, connected to the upper blocks L'. The arrangement is such that the puller-carrying bars L L2 are moved vertically toward and from the fabric X in such manner as to alternately pass the pnllers, hereinafter described, in opposite directions through the meshes of the fabric. The pullers are shown in detail in Fig. i. The upper pnllers M are arranged in a transverse row across the plane of the fabric X in the puller-carrying bar L. rlhe pullers of the upper row or series are all of the same size and construction and have their lower ends m in the same horizontal plane. As shown in Fig. 4, each puller is formed with a square or rectangular shank nt', secured at its upper end to the miller-carrying bar L and at its lower end /nl/ tapered. On one side the lower end of the puller is cut away to receive a pi voted jaw m2, the point or lower end of which is tapered to correspoiul with the tapered end of the body of the puller. The lower end of the puller is also provided with a recess m" to receive the thread to be interwoven in the fabric, and the lower surface of the recess is rounded to form a seat nl. for the thread. rlhe jaw m2 is provided with an arm mx, which extends over the top of the seat m1 when the jaw is closed and prevents the thread from escaping at that time. The jaw is connected at m5 with. a rod on", which extends vertically through a groove or recess in the shank of the puller and is connected at its upper end with a cross-bar 111.7. By reciprocating the bar m7 vertically the jaw mil may be opened and closed.

All of the pull- IOO IIO

ISO

ers in the upper series are constructed in this way, and all of their Vrods m6 are connected with the cross-bar m7. This bar is carried by arms m8, mounted on a shaft m9, that is in turn mounted in brackets m10, projecting rearwardly from the puller-carryin g bar L. The cross-bar m7 carries a. stud fm, which projects into a groove in a cam m12, mounted on a shaft m13, projecting rearwardly from the puller-carrying bar L. rlhis shaft also carries a ratchet-wheel m14, which when it is actuated causes the cam to be turned to reciprocate the rods m6 at proper times, and thus open and close the jaws of the pullers. The ratchet-wheel m14 is operated by a springpawl m15, pivoted on a rod mi, projecting from the main frame. This pawl is so located as to operate the jaws to both open and close them while the hooked ends of the pullers are beneath the fabric and before they return through the meshes thereof. The lower set of pullers is similarly constructed and similarly operated, the operating-pawl m17 being mounted on a bar m18 below the plane of the fabric and being constructed to actuate the ratchet of the operating-cam to open and close the lower series of hooks N after they have been projected through the meshes of the cloth and while they are on the upper side thereof.

The jaws of the upper series of pullers M open toward the right of the machine, while the jaws of the lower pullers N open toward the rear. Each puller in the lower series is arranged directly under a puller in the upper series and the number of pullers in each series corresponds with the number of pairs of warps in the fabric over which the additional threads are to be drawn.

Each additional thread to be interwoven in the fabric is supplied by the picker to a device which l call the first threader,"7 which presents it to the iirst puller of the lower series of pullers and it is in turn fed to the other pullers by other independently-operated threaders arranged on opposite sides of the fabric.

The threaders on the upper side of the fabric are all mounted on'a plate O, secured to and projecting forwardly from a bar o, having a dovetailed connection with a correspondingly-formed groove 0 in a bar 02, arranged transversely across the machine at its rear end and bolted to the side castings A A. A reciprocating transverse movement is given to `the bar o and to the plate O, carried therebyJ by a bell-crank lever O2, which is slotted at o3 to receive a pin o4, carried by the bar o. The lever O2 is pivoted on a bracket o5, proj ectin g from the bar o2, and is connected by a link o with the upper end of a lever 0T, pivoted on a cross-shaft O,and connected by a link oS with the upper end of a lever o, pivoted on a cross-shaft 010 and carrying on its lower end a roller o, working ina groove o12 in a cam O3 on the main driving-shaft B. By

this mechanism a transverse movement is given to the threader-carrying plate O and the Athreaders carried thereby, and these threaders also have an independent transverse movement and also a longitudinal movement, as will be hereinafter described.

The threader-plates P P, are mounted on the plate O and are held in engagement therewith by abolt p, which extends through holes p2 in the threader-plates, and carries at its upper end a spring-cap p4. The upper plate P is slotted at p5, and through these slots eX- tend pins p6, secured to the lower plate P',

thus permitting the upper plate to have a somewhat greater transverse movement on the plate O than the lower plate. A spring p7, secured to the top of the bolt p and to the upper threader-plate P, pulls this plate to the left, but permits the plate P to have the transverse movement independently of the plate P', above referred to. A lug p, projecting downwardly from an arm on the plate P, is

adapted to strike against the edge of the plate O, and thereby limit the transverse movement to the left of the upper threader-plate.

To the front end of the bell-crank lever O2 is pivotally connected a link 013, in turn connected to a pin o, projecting upwardly from the lower plate P through a slot p8 in the upper plate P. By this mechanism the threaders, in addition to being moved transversely by the plate O, are also given an independent transverse movement over the plate. A longitudinal movement over the plate O is imparted to the threader-plates by the parallel rods Q, connected at their front ends to lugs q, projecting upwardly from the plate P, and connected at their rear ends to arms q', projecting downwardly from an oscillating shaft Q, mounted in standards q2 on the bar 02. A curved arm Q3, extending rearwardly and downwardly from the shaft Q, is connected bya link g4 with the upper end of a lever Q2, pivoted on the shaft O and connected by a link g5 with a lever Q3, pivoted on the shaft o10 and. carrying on its lower end a roller QG, working in a groove in a cam Q4 on the main driving-shaft B. The plates P P are connected in the manner above described by pins p6, secured to the lower plate, and the transverse slots p5 in the upper plate,so that they move together longitudinally of the machine, having no independent movement in this direction, the diameter of the pins p6 being approximately equal to the width of the slots p5, and the connections between the rods Q and the threader-plates are loose enough to allow the latter to move transversely, as before described.

Below the fabric is another threader, which moves independentlyof the upper threaders. A plate R, secured to a bar r, supports another plate R, that is adapted to reciprocate longitudinally of the machine on the plate R and transversely with said plate The bar 'r has a dovetailed sliding connection with a slide-bar R2, arranged transversely below the fabric and bolted to the frame-castings A A'.

A pin 9" on the bar `r extends through a slot r2 in the cross-bar R2 into the slotted end of a bell-crank lever R3, )ivoted to a bracket r3 on the slide-bar R2, its opposite end being connected by a link r4 with the upper end of a lever R4, pivoted on the shaft O' and connected by a link r with a lever R5 on the shaft 01", and carrying at its lower end a roller fr, working in a groove rT in a cam R on the main driving-shaft B.

The plate R is reciprocated longitudinally on the plate R by means of links frs, pivotally connected to lugs r, projecting downwardly from the plate R, and at their rear ends connected to arms rw, projecting from a shaft r, mounted in suitable bearings below the bar R2. The shaft fr is connected by an arm and pin yr12 with the slotted end of a lever RT, mounted on the shaft om and carrying at its lower end a roller r1, working in a groove fr in a cam R8 on the main driving-shaft B. The pla-te R is connected to the plate R by pins extending through slots which guide it as it is moved back and forth.

All of the cams for operating the threaders are, it will be observed, mounted on the main driving-shaft, and the connections are such as to cause the threaders to move harmoniously and to co-operate with the pullers to insert the diagonal threads in the fabric. The lower threader-plate R at its front edge is formed with a transverse series of holes S, corresponding in number to the number of pullers in each row. The holes a-re of suliicient size to allow the pullers to reciprocate through them while carrying threads.

Each plate P Il has at its front end a series of forwardly-projecting teeth T, separated by recesses or spaces f, the sides of the front ends of the teeth being cut away to form curved fingers t. The recesses 011 the teeth of the upper plate are on the left-hand side thereof. Those on the teeth of the lower plate are formed on the opposite side, so that when the plates are in one position (see Fig. 2 or Fig. 23) the fingers shall overlap and form oblong' narrowopenings, but when in another position form between them wide nearly-circular openings, as shown in Fig. 19, large enough to permit the pullers to reciprocate through them. lVhen the fingers overlap, each pair may be projected forward without danger of having the pullers come in contact with them, and the oblong openings are such as to hold the free ends of the threads out of the path of the pullers to the right of them.

The device U,which Icall the iirst threader, is mounted on the plate O and is adapted to reciprocatelongitudinallythereon. lt has a dovetailcd rib n, fitting a correspondinglyformed groove u in the top of the plate O, and is provided with two jaws U U2, the rib n being formed on the lower jaw, and this jaw has only a back-and-forth movement on the plate O. The upper jaw is pivoted to the lower jaw at n2, and a spring ui in rear of the pivot normally closes the jaws. The inner faces of the jaws are inclined or beveled at u ui, so as to form an inclined opening between them when the jaws are closed, as indicated in Fig. 22. This space or opening is of such size as to hold the diagonal thread in. such manner as to prevent it from twistin or turning, but permit the thread to be withdrawn from between the jaws when operated upon by a puller, and the diagonal arrangement of the opening holds the thread out of the path of the open jaws of the pullerto the right of the thread. A curved pinV n projects downwardly from the upper jaw into a recess in the lower jaw in front of the pivot u2 and prevents the thread from passing too far back in the jaws, being so located as to hold the thread at the proper time in such a position as to cause the first puller of the lower series of pullers to engage with the thread and pull it downwardly over a pair of warps at the left-hand edge of the fabric. A reciprocating longitudinal movement is given to the first threader by a level' U3, pivoted to a bracket a7 on the cross-bar o2 behind the upper threader-plates. The lever is connected with the plate l by a pin 'u8 on the plate extending through a slot at u" in the lever, and at its slotted forward end it is connected with the rear end of the lower jaw U2 of the iirst threader by a pin nl", which extends through the slot in the lever. The lever U3 being arranged diagonally with reference to the transverse movement of the threaderplates P P and their supporting-plate 0 and the lever being connected with the threaderplate P and with the first threader by a slotand-pin connection, a short back-and-forth movement will be given to the lirst threader when the threader-plates move transversely on the supporting-plate O and a greater longitudinal movement will be given to the first threader when the supporting-plate O is moved transversely. The connections between the first threader and its operating-le ver and between. this lever and the threaderplates are such as to permit the threaderplates to move transversely without giving a transverse movement to the iirst threader, which, however, is moved transversely with the supporting-plate O.

The jaws of the iirst threader U are narrow and can be reciprocated back and forth between adjacent pullers, the arrangement being such that the jaws are always closed when the iirst threader is moved forward; but when the first threader is moved tothe left and is drawn rearwardly by the lever U" the upwardly-projecting rear end u of the upper jaw rides under the inclined under surface u of a bracket U, secured to the transverse bar o2. lVhen the first threader is thus moved to the left and to the rear and its jaws are opened, the picker is moved forward through its jaws and is operated to grasp the end of the diagonal thread Y to be inserted, which thread at this time projects a short distance from the guide J, the jaws of the picker being opened IOO lIO

and closed, as hereinbefore described, at this time to grasp the end of the thread and to draw it diagonally across the fabric as the picker is retracted. After the picker has receded the first threader is shifted, the jaws closed, and the thread Y is held between them, and when thus held is presented to the first puller of the lower series of pullers. After the thread has thus been laid in the first threader the pincher K is operated to grasp the end of the thread Y, at the same time operating the knife or cutter k to sever a strand of proper length. The pincher is constructed to hold thethread Y while it is being operated upon by the first puller in the lower series of pullers; but after it is thus operated upon by j the puller the fabric is fed forward and other devices are employed for holding the said thread, and also other threads immediately succeeding it, while they are being partially interwoven and until they are held tightly enough to prevent them from being pulled through the fabric in the wrong direction.

As y will be more clearly hereinafter described, the pullers operate upon the threads Y to pull them over the warps and under the wefts through the meshes of the fabric while it is being fed forward, so that these threads are woven in a diagonal direction entirely across the cloth, growing shorter and shorter until they are entirely interwoven. To do this it is necessary that the threads at their left-hand ends shall not be pulled through the meshes; but they must be held positively. After the threads have been partially interwoven they will be sufficiently held by being vtied to the fabric itself; but at first they must be held by devices especially constructed for that purpose.

rlhe pincher K, as above described, holds the thread while it is being operated upon by the first puller in the lower series of pullers. In order to hold ther threads after the cloth has been fed forward step by step a distance corresponding to one or more meshes, l employ a clamp V, consisting, primarily, of a base-plate 1; and a j aw u, pivoted to a standard /02 on the base-plate and having at its rear end a tongue c5, adapted to pass between the tines of the bifurcated front end of the pincher. The plate U is adapted to reciprocate longitudinally in guide-plates r3 on the plate K',

' and is operated by a link V', connected with Vthe upper clamp-bar of the feed mechanism in such manner that the clamp V is moved back and forth coincidently with and to the same extent as the feed mechanism. The upper member o of the clamp is opened and closed by a rod V2, pivoted to a lug Q24 on the rear end of the jaw u and connected at its front end with an arm o6 on the shaft h4 of the feed mechanism, the arrangement being such that the jaw u is opened and closed coincidently with the opening and closing of the clamp-bars.

While the threads Y are being inserted through the first few meshes of the fabricl j them.

they will be grasped by the clamp V and held at their left-hand ends and until they have been partially interwoven. Afterward the threads pass the clamps, and other threads drawn bythe picker and severed by the cutter are held for a short time in the clamp for a similar purpose.

All the mechanism has thus been fully described and the operation of some of the parts has been indicated.

The feedingforward of the fabric into which the additional threads are to be inserted has been fully described and is easily understood. As the fabric is thus fed forward step by step, the picker is reciprocated across the top of the fabric to draw threads Y across the upper threader-plates. The picker as it moves forward passes through the open jaws of the first threader and through or past the open pincher K, the clamp V being withdrawn from the path of the picker and the first threader being in the position indicated in Figs. 17 and 21. lVhen the picker has receded, the pincher descends, operates the cutter, and in connection with the block XV grasps the thread Y near its severed end and holds it while being drawn through the fabric by the iirst puller in the lower series of pullers.

Referring now to the diagrams Figs. 19 to 31, inclusive, I will describe in detail the operation of weaving the additional threads into the cloth. For convenience reference is first made toFig. 21, wherein the first threader is shown in its retracted position open and the thread Y is assumed to have been just laid by the picker. The threader-plates P P are moved to the right and retracted, and the fingers t t are overlapped and are arranged behind the plane of the pullers, and the threads are held up in an inclined direction, as indicated in Fig. 22. This figure also indicates some of the lower pullers as just rising to pass through the cloth. After they have passed through the cloth the rst threader and the threader-plates P P are projected forward to lay the threads in the jaws of the lower pullers, as indicated in Figs. 23 and 24, which then descend, the pincher K grasping the thread Y, which passes through the first threader. The lower pullers as they were projected upwardly passed through the holes S in the lower threader-plate R', and on their descent, of course, returned through these holes, drawing the diagonal threads with Figs. 25 and 2G show how the threads are drawn downwardly through the holes S in the lower threader-plate by the pullers N. As soon as the threads are thus drawn through the holes S, the fabric is fed forward one step and the plate R is moved backwardly under the plate R, the plates R and R at the same time being moved to the right, as indicated in Fig. 27, the threads being held between the front edges of the plates R R, as indicated in Fig. 31. This will carry the threads to the right of the vertical planes of the corresponding pullers of the upper set. The up- IOO IIO

per threaders are then moved from the position shown in Fig. 23 to the position shown in Fig. 1S), the plate l being moved relatively to the plate l, so that the iin gers spread apart and form openings through which the upper pullers may pass. At the same time a slight backward movement is given to the first threader, as well as to thek threader-plates. lVhen the threaders are in this position, the upper pullers descend in the manner indicated in Fig. 2S. After theyhave thus descended to the position shown in Fig. the plates R R are moved to the left, as indicated in Fig. 2S), causin the threads to be moved into the open jaws of the upper' pnllers. Then the jaws are closed by the mechanismheretofore described, and the upper pullers rise through the openin between the fingers, as indicated in Figs. 1S) and 20. After they have thus risen and have drawn the diagonal threads under the wefts the first threader and upper threaders are moved into the position shown in Fig. 2l., when a new thread is laid by the picker in the jaws of the open first threader. 'ihen the lower set of pullers is projected upwardly through the cloth and then the first threader and the threader-plates l) l are projected forwardly, as indicated in Fig. 23, laying the diagonal threads in the jaws of the lower pullers N, which pull them over the warps and down through the lower threader in the inannerheretofore indicated. The operation continues in the same way, the first thread introduced being supplied by the first threader to the first puller of the lower series of pullers. This draws it down through a mesh and over the first pair of warps at the edge of the fabric. The fabric is then fed forward and the lower threader transfers the thread to the first puller of the upper series of pullers,which draws it under the weft and up through the next mesh. The thread is then taken from the first puller of the upper series bythe threaderplates and is transferred to the second puller of the lower series, and in like manner the thread is supplied by a threader to a puller of one series and then from the puller of that series to a puller of the other series, until it is entirelyinterwoven, while the cloth is being fed forward. The threaders and pullers are so arranged as to prevent the threads from twisting or turning, their glazed sides always being uppermost. The bar K on the front of the plate K/ co-operates with the lower threaders, as indicated in Fig. 3l, to prevent the twisting of the threads. The clamp V is during these operations actuated correspondingly with the actuation of the feed-clamps to hold the threads while being pulled through the first few meshes in the manner before indicated.

At first the operation of interweaving the diagonal threads is slow. I do not mean by this that the parts do not operate rapidly; but l mean that each thread is necessarily moved back and forth a number of times through the meshes of the cloth, over the warps and under the wefts, before it is interwoven; but the operation grows faster and faster, as after a while a number of threads are operated upon corresponding with the nun'iber of warps in the fabric, and in a fabric which has ten warp-threads or ten pairs of warps ten additional threads are drawn over the ten warps and under the we fts at cach operation of the machine, thus in effect interweav in g a single thread entirely across the fabric at one operation of the mechanism and as a result giving the machine a capacity for great speed.

The drawings show the machine organized to insert one set of diagonal threads. To insert the other set, the fabric may be reversed or turned over and run through the machine and operated upon in precisely the same way as it was operated to insert the first set of diagonals.
