Looivr non WEAVING WHEREIN THE wnrfrs ARE nnawn FROM sTATIoNARY SUPPLIES.

Application filed May 4, 1925, Serial No. 27,883, and in Great Britain May 5, 1924.

This invention relates to the-mechanism for operating the weft threads lin looms for weaving wherein the wefts are drawn from stationary supplies and such mechanism is specially applicable. for use with the invention set forth in our prior British Patent No. 168,444 dated J une 14, 1920, but it must be understood that the present invention is also applicable for use with other classes of looms for weaving wherein the wefts are drawn from stationary supplies.

The present invention will be described as applicable to the machine set forth in our prior patent, and will be fully understood from the following description aided by the annexed drawings.

Figure l is a side elevation of a portion of a loom frame with two of our reciprocating rods or tubes carrying weft threads and also showing cooperative selvedge shuttles and their carrier, the reciprocatory rods or tubes being in the starting position for applying the weft threads across the fabric.

Figure 2 is a plan of the two reciprocating rods or tubes and the cooperating shuttles and their carrier shown in Figure l.

Figure 3 is a side elevation of a selvedge shuttle and its carrier.

Figure 4 is a plan with a portion of the carrier broken away to show the selvedge shuttles.

7We employ singly or in multiple, as required, rods or tubes or pairs of multiples of pairs of lods or tubes (in the drawings we show a pair 28, 28) positioned parallel and each or each pair or the whole are connected at or near the outer end to a device comprising a sleeve A or carriage slidable upon a bar or bars orl track or tracks 52, to prevent revolution, such device A or devices being reciprocated by any desired mechamsm.

At the inner end of each rod 28 we pivot, in rule joint fashion, an arm B havingan eye or roller 3l or other means for carrying a weft thread 29. lThe warp threads are shown at P.

Each weft thread is run from a reel 34, constituting a stationary weft supply, over rollers C, 1 one of which, C1 is capable of being bralred to apply tension to the thread, and then around a roller or rollers D or eyes on the rod 28 to the eye or roller 31 in the arm B and connected with the material E from which, for example, a door mat is being made.

Each shuttle 36 is formed with a curved nose piece F and with extension pieces G at top and H, H at bottom and each shuttle is also curved on one side, and such shuttles 36 are positioned in a casing J having an opening N along the top froinfront torear and also having an openin in front thereof'between the shuttles and t e recesses K, L, L, to permit the arm B to pass between the shuttles. The recesses K, L, L, correspond in shape to the projections, G, H, H, and are so constructed that the shuttles 36 are loosely held therein, the projections Gr, H, H preventing displacement of the shuttle when a weft thread 29 is passing round it and each shuttle 36 carries a thread which is drawn from the non-curved end 43, such threads forming a special warp or selvedge thread.

Near the nose ends of the shuttles 36 are positioned twopivoted spring controlled gates M, M which are primarily intended to divert the threads on to the outside of the shuttles 36 on the return journey of the rod 28, after the arms B of the rods 28 in their forward journey have acted upon same and pushed them o en and the springs have returned them to t eir normal position.

In operation and after the warp threads P are crossed in the usual manner before applying the weft' threads, the rod or rods 28 is or are projected across the fabric E, carrying with Vit or them the weft threads 29 in the form of loops and then the pivoted arms B pass through the opening N and strike the gates M, M open them and pass by them, carrying with them the weft threads 29 the gates M, M closing under action of the springs and on the return journey the arms B will become straightened or nearly straightened out with the rods 28 and the weft threads 29 will be pulled up against the gates M, M which are preferably curved or angled, and the threads will ride over same and pass over the noses F and around the shuttles 36 and under the pmjections` H, H which loosely fit the holes L in the shuttle carrier, such action carrying th(l loops of the weft threads around their respective special warp or selvedge thread or threads drawn from the shuttle or shuttle 36 whereby the weft threads are retained at the selvedges of the fabric remote from the weft supply. After the return movement oft the rod or rods 28, the usual action ofthe Warp threads takes place. A repeat moveA ment of the rods then occurs. lil/what We do claim as our-invention and desireto secure by Letters Patent is 1- l. lln looms wherein the wefts are drawn from stationary supplies, mechanism for operating the weft thread connarising reciprocatory member, a track for guiding said member, and an arm hinged to said member to carry the weft thread, in combination with a selvedge shuttle for the weft thread, a casing 'for the shuttle having holes therein, the shuttle having a spring-controlled gate at its nose end and having projections eX- tending into said holes in the casing, said reciprocatory member acting on the springcontrolled gate to open and pass the same and 'carry the weft thread beyond it. during the outward journey and draw the weft thread loop around the selvedge shuttle and a selvedg'e thread drawn therefrom during the return journey of said member.

2. In looms wherein the Wets are drawn from stationary supplies, mechanism 'for operating the wett thread comprising a reeiprocatory member having a Weit carrying arm pivoted thereon, in combination with a shuttle, and a gatecooperative therewith, the gate being located in the path of said armY whereby it will be deiieeted thereby When vsaid member is advanced, and the gate being movable, after said arm has passed it, into a position to deflect the Weit thread around the shuttle during return. movement of said member. Y

In testimony whereof We have hereunto set our hands.
