The diverging the warp, as and for the purposes set forth dotted lines in this ligure represent ashed 1, in Kuetts patent, No. 653,249,0f July 10, 1900, formed in the top lift of the main or ground and the selvage-weft thread is controlled by warp shed, at, say, the inner edge 25, by rais- 10o 5o tension and take-up devices, as also set forth ing at this edge certain of the warps (which in said patent. It is in this combination of I term tai'fetawarps) above the groundwarps in the top lift for the purpose of receivv ing the loop of selvage-weft. The bottom lift of the main or ground warp shed is omitted from this figure. Fig. 8 is a side view of the same parts in the position they occupy in Fig. '6. Fig. 9 is a side elevation of a detail illustratve of the guide in which the horizontal needle-carrying bar is supported and reciprocates. Figs. 10, 1l, 12 are views of a modi- 'fication hereinafter referred to.

The batteri 2 is the batten of an ordinary silk power shuttle-loom. The reed 3, Figs. 7, 8, is set between the main part 2 of the batten and its lower portion 26 in the usual way.

The warps are arranged as if ordinary twin fabrics were in questionthat is to say, several dents in the middle of the reed are left empty, so as to form a line of division between the two set-s of warps. These warpsthe ground-warps-are of course all operated at the same time to form the shed, and the ground-shuttle which carries the ground-weft passes at each movement from the outer edge of one set of warps to and beyond the outer edge of the other set of warps, just as usual in weaving this class'of fabrics, and by this shuttle the exterior opposite selvages of the twin fabrics are formed, as will be understood without further explanation.

The taffeta-warps for the selvage-sheds 1 are threaded through four heddles instead of two in order to form alternately at each of the interior opposite edges 25 27 of the twin fabrics a shed 1 in the upperlift of the groundwarp shed-that is to say, at one beat up to form the shed 1 in the edge 25 and at the next succeedingr beat up to form the shed 1 in the edge 27, and so on. This shed 1 may be obtained in various ways, preferably by setting the harness-eyes for the taffeta-warps of the top lift of this auxiliary shed higher than those for the ground-warps in the top lift of the ground-warp shed.

Along the lower edge of the upper portion of the batten is formed alongitudinal rabbet 4, Fig. 9to receive the legs of guide-brackets 5, which are secured therein by screws. Each bracket contains a pivoted antifrictionroller 6, and the long reciprocating bar 7 passes through the guide-brackets 5 and is supported on said rollers 6. This bar carries the horizontal needle or needles for laying the selvage-weft. The bar 7, preferably of steel, is perforated with holes about two millimeters in diameter and six millimeters apart.

T-shaped supports 8, preferably of copper, are fixed to the bar by screw-studs 9, which pass through slots in the horizontal arm of the support and holes in the bar and have small n uts screwed onto their screw-threaded end to firmly clamp the supports to the bar. The slots formed in the horizontal arms of the T-shaped support are about twelve millimeters long, and as the holes in the bar are spaced only six millimeters apart the supports can be applied to and secured to the bar at any point throughout its length, because 2 'fodere g some portion of each slot must also be opposite to some hole in the bar.

A needle-carrier 10, made of copper, iron, aluminium', or other suitable material, is adjustably xed to the vertical stein of the T- shaped support 8 by a set-screw 11, which passes through a slot in said vertical stem into a threaded hole in the needle-carrier.

The needle-carrier 10 at its lower end is curved toward the reed (see Figs. 7 and 8) and has formed in this end a tubular passage to receive the horizontal needle 12, which is secured in place therein by a set-screw 13. This needle is a'stiff steel needle about one millimeter in diameter. Itis fixed by its center to the carrier, so that it protrudes from each side thereof, and each of its ends is slightly pointed and has an eye to receive a thread, and is so located that it will be in a plane exactly between the two lifts of the auxiliary shed 1 when the latter is open.

rlhe length of the needle varies with the size of the selvage it is desired to weave. On an average each of its ends in length should exceed by about twelve millimeters the width of the auxiliary shed.

Each end of the needle takes its own weftthread. These threads are marked 14 and 15, respectively. Each thread is-conducted from its spool to the needle and on its way to the latter passes to and through a tension and take-up apparatus. For this purpose I prefer to make use of the tension and takeup apparatus described and illustrated in the Kuett patent, No. 653,249, hereinbefore mentioned; but any other known or suitable devices for the purpose can be employed.

The horizontal needle is so located that it will enter and lay a loop of weft-thread in the interior opposite edges 25 27 of the twin fabrics alternately-that is to say, so that at one beat up of the batten one of its ends will lay a loop of the weft-thread 14 in the auxiliary shed 1 in the edge 25 and at the next succeeding beat up the other of its ends will lay a loop of the weft-thread 15 in the auxiliary shed 1 in the edge 27, and so on. The reciprocatory movement of the needle for this purpose is derived from the longitudinal sliding bar to which it is attached, said bar being actuated to thus move by a suitable powerdriven cam and connections. Mechanism of this .kind is well known and in common use and requires no illustration here.

Upon the upper portion of the batten is mounted the vertically-reciprocable frame which carries the vertical needles, which are designed to retain and hold the loops of selvage-weft deposited in the edges 25 27 until they are beaten np. This frame, which may be of any suitable construction, consists in this instance of two longitudinal bars 19, bound together by end-connecting plates 18, which are mounted and adapted to slide up and down on standards 16, secured by their feet or bases 17 to the top of the batten. The bars 19 are separated from each other by a IIO lspace of about three millimeters, forming a longitudinal slot in which the carriers of the vertical needles can be adjustably secured. These needle-carriers 21' (whose construction is fully shown in Figs. 1, 7, and 8) are fixed to the vertically-reciprocating frame by small bolts 20, which pass through the carriers and the slot between the bars 19 and are held in place by nuts on their screw-threaded ends.

Each needle-carrier is approximately E- shaped in side elevation. To its middle limb is pivoted the cube-shaped counterweight 22, through which passes the vertical needle 23, said needle being secured in place therein by a suitable set-screw. The top and bottom horizontal limbs of the E-shaped carrier are slotted for the passage of the needle which projects into them. rlhese slots, which serve as needle-guides, are indicated by dotted lines in Figs. 7 and 8. The slot in the upper limb is closed at both ends. The slot in the lower limb is open at the end next to the batten and is also made a little flaring, so that the vertical needle may readily move out from and return back into the slot as it swings on its pivot to and from the reed 3, a light spiral spring 24 being used to reinforce the action of the counterweight 22 in tending to return the needle to its normal vertical position.

The needle 23 is a long very flexible needle about twelve millimeters in length and tapered for about olie-half of that length.

A vertical needle is needed for each one of the two interior opposite selvages of the twin fabrics, and each is so located that its pointl will be directly above the inner extremity of its selvage.

In case it is required to weave ribbons having much narrower selvages than herein illustrated it may not be possible to bring the needles 23 near enough together if each has its own carrier. In such case I may employ a single carrier with a hinged counterweight 22 of sufficient size to permit the two needles to be mounted in it. These needles reciprocate up and down with the frame on which they aremount-ed. lVhentheydescend,theyserve to retain the loop of additional selvage- weft 14 or 15 until the beat up of the hatten, after which they rise, leaving the weft-loop in the fabric, and are ready for a fresh descent. 'lhe frame which carries these needles can be actuated by any of the numerous and wellknown devices for that purpose employed in needle-looms and too well known to those skilled in the art to require illustration or description here.

The horizontal bar 7, to which the horizontal needles 12, which lay the selvage-weft, are attached, is given six successive different movements necessary for effecting the workviz., first, about thirty millimeters from right to left, (see Figs. 1, 2;) second, about thirty millimeters from left to right, (see Figs. 2, 3;) third, about seventy millimeters from right to left, (see Figs. 3, 4;) fourth, about thirty millimeters from left to right, (see Figs. 4, 5;)

fifth, about thirty millimeters from right to left, (see Figs. 5, 6;) sixth, about seventy millimeters from left to right, (see Figs. 6, 1.) These six movements take place during two complete beats of the lay or batten, and they should be so timed that movements 1, 2, 4, and 5 take place at the moment of raising the warps and movements 3 and 6 at the moment of lowering immediately after the beat of the reed.

The operation is as follows: Suppose the horizontal needle 12 has just nished its sixth movement and is in the position shown in Fig. 1 with its end which carries the auxiliary weft-thread 14 several millimeters from the right-hand edge of the warps of selvage 25. The vertical needles 23 are in their raised position. A shed is opened in the warps of the twin fabrics, the shed being of the usual height for the body of the fabrics and for the selvage 27 of the right-hand fabric, but having an additional lift for the threads of the innerselvage 25 of the left-hand fabric, so as to form the auxiliary shed 1, Fig. 7. The shuttle, carrying the ground-weft 28, is rnow thrown through the ground-shed, and simultaneously the horizontal needle makes its first movement from right to left, Figs. 1 and 2. At the same time the batten 2 commences its forward movement and the vertical needles 23 commence their descent. By the time the batten has completed one-fourth of its forward movement the horizontal needle has completed its second movement from left to right, Figs. 2, 3, and remains in this position until the beat up; but the vertical needle 23 before this second movement of the horizontal needle has descended far enough to engage the weft-thread 14, so that said thread is left in loop form in the auxiliary shed 1 and is there held by the vertical needle until after the lowering of thewarps and the beat up. As the batten advances the vertical needle meets the fell of the fabric before the reed, and it consequently turns upon its 'pivot toward the reed, as indicated in Fig. 3, still, however, maintaining its engagement with the loop of weft 14 until the beat up, (see Fig. 3,) after which it rises and quits the loop. At this moment and before a fresh lift has been given to the warps the horizontal needle 12 is caused to complete its third movement, from right to left, Figs. 3, 4, which brings it into a position in which its right-hand end carrying the auxiliary-weft thread 15 is several millimeters from the left-hand edge of the warps of the inner selvage 27 of the right-hand fab-` ric. An auxiliary shed 1 is now formed in this selvage,'as indicated diagrammatically in Fig. 4, while the selvage 25 this time is shed in one with the body 'of the twin fabric and has no auxiliary shed 1. The groundshuttle is thrown through the main shed, and simultaneously the fourth movement of the horizontal needle 12, from left to right, Figs. 4, 5, takes place, thus carrying the auxiliary weft 15 through the shed 1 of selvage 27.

At the same time the batten again moves forward, and the vertical needle 23 descends until it engages the thread 15, and then the fifth movement of the needle 12, from right to left, Figs. 5, 6, takes place. The thread 15, however, is retained in the shed l of selvage 27 in loop form by the Vertical needle which opcrates as hereinbefore described and quits the loop only when the beat up takes place. It then rises, and the sixth movement of the horizontal needle, from left to right, occurs, I

Figs. 6, 1, which brings the horizontal needle 12 back into position to again lay a loop of weft 14 in selvage 25. Thus each one of the selvages 25 27 is truly edged every second beat up, and no thread can unravel. The ground or shuttle weft 28 aids in keeping the supplemental or selvage- weft threads 14 and 15 firmly in the selvages 25 and 27, and if the apparatus is well regulated and the work performed with proper care the loops are concealed in the fabric and are invisible. The twin fabric thus obtained is divided after dyeing and dressing, the cut'ends of the ground-weft threads 28 are singed, and the fabric appears to be really edged by the supplemental threads and does not unravel. Besides taffeta-selvages Gros de Tours selvages may be made, or imitation pearled or other ribbon selvages can be produced.

I may use the devices hereinbefore described for obtaining other eects in weaving than selvages-as, for example, I can superimpose bands upon the body of a fabric by properly positioning the verticaland horizontal needles with reference to the same-and I desire to be understood as including this within my claims, and unless these bands are placed very close together a single horizontal needle can be used for each band, and it can be made to lay a loop of supplementary weft at each beat up of the ground-weft. This modification is shown diagrammatically in Figs. l0, ll, 12, in which is represented the sequence of operations required to place two bands upon the body of a fabric, the bands being woven at the same time with the body of the fabric. The auxiliary sheds 30 are formed in the same way as the selvage-sheds l, hereinbefore referred to. They are, however, located not at the edges of the body of the fabric, but between the edges. The auxiliary-weft threads (corresponding to the selvage-weft threads 14 15) are shown at 3l. rPhe horizontal needles are shown at 32. Each one of course will have associated with it a vertical loop-retaining needle; but it has been deemed unnecessary to represent the latter. The needles 32 are single needles and at each pick they make one complete reciprocation, so as to lay a' loop of auxiliary weft for each pick, which is beaten up at the same time with the ground-weft 28. In Fig. 10 thencedles are shown as about to enter the auxiliary sheds, in Fig. 11 as having passed thro ugh the sheds to the far end of the stroke, and in Fig. 12 they are represented as having withdrawn therefrom to the position shown in Fig. 1, and the loops deposited by them are represented as having been beaten up With the body fabric. This sequence of movement takes place at each beat up of the reed, with the effect of superimposing bands upon the body fabric.

This invention is not limited to the use of any particular shuttle-loom, nor to the employment of any particular number or arrangement of needles, nor to the particular position of the needles, for the saine results can be obtained by locating the reciprocating vertical needles point upward below the reed.

The apparatus hereinbefore described and illustrated has been designed more particularly with a view to its adaptation and convenient application to existingshuttle-looms; but novel looms working with shuttles and needles in accordance with myinvention may be designed.

Having now described my invention and the manner in which the same is or may be carried into effect; I state in conclusion that I do not confine myself to the structural details hereinbefore described in illustration of my invention, for manifestly the same can be widely varied without departure therefrom; but

What I claim as new, and desire to secure by Letters Patent, is as follows:

l. In a shuttle-loom, and in combination with the means for weaving the body fabric, provisions for forming upon one of the lifts of the main or ground shed an auxiliary or supplemental shed, a needle mounted on and movable lengthwise of the lay and adapted to insert an auxiliary-weft thread into said supplemental shed,and a weft-loop retainingneedle also mounted on the lay and reciprocating thereon in a path transverse to that of the weft-inserting needle and adapted to yield toward the reed and the edge of the warp, substantially as and for the purposes hereinbefore set forth.

2. In a combined shuttle and needle-loom substantially as described, the combination with the batten and the reed, of a doubleended horizontal weft-inserting needle adapted to receive an independent weft-thread at each end, said needle being mounted on and reciprocating lengthwise of the batten, and flexible oscillating weft-loop retaining-needles mounted on the lay and reciprocable thereon in a path transverse to that of the doubleended vhorizontal needle, substantially as and for the purposes hereinbefore set forth. f

In testimony whereof I have signed this specilication'in the presence of two subscribing witnesses.
