SPECIFICATION forming part of Letters Patent No. 609,152, dated August 16, 1898 Application filed A ril 80, 1897. Serial No. 634,562. (No model.) Patented in France September 9, 1893, No. 219,561, and in Germany January 22, 1894, No. 84,912.

To aZZ whom it may concern:

Be it known that I, FLORENT PIERRE LE- DREUX, of the city of Paris, France, haveinvented a Machine for Making Beaded Trimmings, (for which I have obtained Letters Patent in France for fifteen years, dated Sep tember 9, 1893, No. 219,561, and in Germany for fifteen years, dated January 22, 1894:, No. 84,912,) of which the following is a full, clear, and exact description.

This invention'relates to a machine for making a gimp Qrother trimming .in which beads are introduced in course of the operation of laying the threads constituting the trimming.

The invention also relates to the new trimming thus produced. The desired result is attained by the introduction into the fabric of a special thread, termed the f third or binding thread, having for its particular function to bind the bead-carryin g thread to the weft of the fabric by a sort of crochetstitch.

Reference is to be had to the accompanying drawings, wherein- Figure 1 is a front elevation, and Fig. 2 a cross-sectional elevation, of a machine embodying my invention. Figs. 3 and 4 show the mechanism for effecting the feeding of the beads to the points where the threads are bound into the fabric. Figs. 5 to 8 show the respective positions of the looper-needles and binding-threads for forming a loop, the said figures being on a larger scale than the preceding figures. Figs. 9 to 12 show the formation of the next following loop, and Fig.

may be employed, the bead-carrying threadsmay follow a more or less extended course or their feed movements may be interrupted according to the design which is to be produced, and the binding-threads which are looped by the needles in the ordinary way of making such trimmings may be of variable number proportionately to the width of the strip or galloon to be produced.

I will describe a machine for makinga gimp strip or galloon having a single weft with nine rows of beads in its width. Thenine binding or crochet threads a forming the loops tying together the other elements of the strip are drawn from bobbins counterweighted by weights at and mounted on a creel I) over a transverse guide-bar a, the

threads at thence passing down through a row of guide-holes in a guide-bar 0 (shown on a larger scale in Figs. 3 and 4,) and are temporarily attached to the take-up roller 0, frictionally driven from a second roller 0. The weft d, which in thisexample is a single cord or twist, is drawn from a bobbin cl and enters one of the guide-tubes 61 four parallel series of which are shown in Fig. 1. The beads f are strung on bead-carryin g warpthreads f',drawn from counterweighted spools in creel 1), these beads f resting, by reason of the inclination of the threads, against a double reed g g, (which acts as a bead-distributer,) between the dents of which reeds the threads pass into the work into which they are drawn by the take-up rollers c 0. Figs. 3 and at show the two toothed members of the double reed or bead-distributer in their different positions. They act as an escapement for the beads and distribute the same as follows: WVhen the upper member g is retracted, the beads rest on the lower member 9', as in Fig. 6, and when the upper member 9 comes forward again it separates the beads on the lower member from those which follow, so that when the lower member is retracted, as in Figs. 7 and 8, the beads which were retained by it will escape and slide down the beadcarrying threads untilthey meet the weft. Besides this backward, and forward motion of the two members of the reed they have a longitudinal movement similar to that of the weft, but of slightly less amplitude, by which means the warp-threads f, which carry the beads, are laid sinuously and will appear thus in the finished fabric. (See Fig. 13.)

Referring to Figs. 5 to 8, I will explain the operations of forming the trimming. At starting the needles 6 are raised. The guide a? is then shifted laterally to the right, while the needles remain stationary, so that the binding-threads a lie across the bead-carrying warp-threadsfl. The needles 6 then descend, taking the binding or crochet threads a into their hooks, the latches of which then close. At the same time the bead-distributer or double reed is operated to release a set of beads, which slide down to'the weft, and the needles form the binding or crochet threads a into loops, which encircle both the warp or bead threads and the weft, as shown in Figs. 7 and 8. The remaining operations are shown in Figs. 9 to 12. tubes 61 are now moved laterally to the left, so as to lay the weft d behind the binding or crochet threads a, which have been thus looped. As soon as the weft has been thus laid the needles rise, passing behind the shoot of weft, and the threads a are drawn backward by a second movement of the threadguide 0, to permit the next following loop to be formed therein. These two movements of the latch-needles e and their binding-threads a are effected simultaneously and then the needles descend again, drawing tight about the weft the loops of the binding-threads.

Then the needles, having inclosed their loops, are again lowered, the weft cl is laid in the opposite direction to the previous shoot. It will be observed that the weft d is only laid when the needles are lowered. wise be observed that the effect of this alternate lateral movement of the weft-laying tubes 01 is to lay the weft-threads sinuously, which effect shows in the finished fabric. Thus the tubes 01 and their operating mechanism constitute a means for laying a weftthread sinuously.

In the interlacing motions of the weftthreads 01 and the binding or crochet threads ct above described the introduction of the beads has been omitted for the sake of clearness. iVhile the needles 6 are completely lowered, the warp or bead threads f are behind the crochet or binding threads at, as shown in Fig. 8, but when the needles rise these binding or crochet threads recede at the same time as the warp or bead threads, Fig. 9, the ascending motion of the needles ceasing for a moment, while the guide effects its lateral motion, carrying the binding or crochet threads. During these movements of the needles and the lateral movement of the thread-guide the bead-threads, each with its bead, and the weft remain stationary. It is when the crossing of the binding-threads by the lateral motion of their guide has been effected that these threads are taken by the needles in their descending movement, thus forming a loop about both the bead or warp threads and the weft-threads, as above de- The weft-guide It will like-' scribed and as shown in Figs. 10, ll, and 12. The operation is thus continued, the needles are completely lowered, the weft is passed behind the threads, the following bead falls into position, and a new loop binds the whole, and so on, as above described. It will be observed that the needles form the thread a into crochet-stitches around the intersections of the weft and warp threads.

The invention is not limited to the mechanical organs shown; but it may be mentioned that to vary the designs produced by the beads suitable cams or other pattern mechanism are used to control or actuate the reeds g g or bead-distributer. To increase the number of beads introduced into the work by each thread, the distance between the two reeds g g is varied proportionally to the number of beads to be produced atone time, and to vary the design produced by the weft several wefts of cord, twist, or chenille may be used, passing each in its appropriate weft-laying tube 01 and being placed upon the bar and in the position determined by the nature of the design which it is desired to produce.

The above-described movements are derived from a shaft h, driven by means of a bevel-gear h 71 from a shaft 71 and geared by pinion 'L' with a wheel 1', keyed on a shaft 70, carrying cams 7o k 70 R of which the first four produce the alternate to-and-fro motion of the thread-guide bars 61 The same movement is imparted to the two reeds g g by cams Z Z and by springs attached to the thread-guide and reed-bars. The reedbars, besides their lateral motion, receive a backward-and-forward motion relatively to each other through connecting-rods from shaft m, which is actuated by cam m or other pattern mechanism, and an arm m the upper reed-bar 9 being actuated by'the connecting-rods m and the lower one 9 by the rods m from another shaft m actuated by lever 70 The needle-bar e is operated from shaft it through parts e 6 and e. The slotted arms of shaft m are also connected by bars a to the guide-bar a of the binding-threads in order to give it its backward and forward movements, the lateral movement of this bar being produced by connection 0 and cam 0.

What I claim, and desire to secure by Letters Patent, is g 1. As a new and useful article of manufacture, a substantially flat strip of trimming.
