STATIONABY YARN GUIDE FR WEAVING LOOIS..

i Application kled November I 1925, Serial No. 68,079, and in rance November 20, 1924. i

The ob'ject 4of the present invention is a yarn guide for weaving looms byvwhlch I automatically v.produce loops consisting of one or more warp threads, and into' which a woof thread is automatically inserted-.either by mechanical means or by hand, bythe use of a shuttle,a simple hook or any other suitable device. Y

Yarn guides such as contemplated by the present invention may be used in various vtypes 'of fabric looms, and are particularly adapted to looms ofthe construction disclosed in my co-pending patent application` Serial Number 68,080.

In comparison with known yarn guides, I obtain the advantage of' holding the two threads, warp and woof in an approved manner until the final loop or knot is completely formed, and also of guiding the latter' out ofthe yarn guide and alon the latter until it reaches the previously ormed loops or knots. Due to the special shape of my said yarn guide, rit will rotect the war against the devices used or inserting t e woof through the latter, since itis constructed so as to comprise an outlet channel', almost closed,which oifers passage only to the Woofl thread when the loop orv knot is Abeing formed.

The said invention is shown in the appended drawings which are given by way of example.

Fig. -1 is a side View of the yarn guide.

Fig. 2 a front view, and Fig. 3 av plan 5 view.

Figs. 4 to 13 showl`vthe various stages of the formation of a'lfoop. Fig. 14. shows a yarn ide in which two warp threads are place l, Figs. 15 to 17 show anotherv method of making a loop. L Figs. 18 to 23 show the rows of loo s or knots obtained with the said yarn gui e. Fig. 24 shows a second constructional form of a yarn guide. i a

/ As observed in the drawings, the arn guide consists of a metal plate l whose ront part has a shape which is suitable for the a work to be performed; 2 is an aperture forv the insertion of 'the shuttle and the placing of the Woof thread 3. The horizontaljpart I 4 of said aperture serves to close the space above the woof thread so that `it .cannot leave its proper part, and itfalso serves to protect the warp thread ,or` threads 5.' In

loop is completely formed; 8 and 9 are eyes for the insertion of thev warp 5, and the number of'such eyes is optional. In Fig. 1 1t w1ll be noted that the distance between Athe eye 8 and the end 10 of the yarn guide somewhat exceeds the distance between the eye 8 and the point 11, so that when a loop 1s completed and is brought-to the pointll, to allow the formation of another loop, it will be prevented fromjamming against the rear part l2 of the yarn guide and chiefly at 11.. But this arrangement is not essential, and the front part of the yarn guide can be so disposed that the distance between 8 and l0 is the same as between 8 and 11.. But in this event care must be taken, during the formation of the loop, that it be pushed .beyond the point 10 'so that the distance In the yarn guide (Fig. 4) is threaded a warp thread 5 leading'v from a roll of warp thread, a bobbin or the like which holds the same; it is unwound automatically or` by means of a drawing roller, as the loop is formed.

The warp thread is inserted first into the eye 9, passes to the other side .of the guide, and then rises and passes through the e e 8, thus returning to the front in order to orm the loop. v f I v In Fig. `5 it is observed that the loop has been formed and that it has a'triangular shape.v When the warp thread is in this.v

position, the Woof thread' 3 .is inserted through the middle of the loop', and as above stated by means of a shuttle or a hook, and either by hand or by mechanical means.

The end/,14.` of the warp thread is now caused to move by suitable means whereby it .oscillates about .the curved lpart of the uide. The radius of this part. increases rom the point 10 onward taking thepoint 15 asa' centre. v l

In Fi 6, the loop formed by the warp thread c oses uponthe woofv thread 3. i

In Fig. 7, thegloop is completely closed upon the Woof thread, and the latter has through position 12the positionlshown in outside the yarn guide.

moved forward upon the inclined part '6 ot the guide.

Flg. 8 shows the loop formed', it has now -rentered the output slot 7 and the woot` thread slides onA the edge 16 so as to obtain the pov sition of Fig. 9 andthence the 4position of Fig. 10. The loop is now finished and is During the formation and the movement of the loop, the warp thread unwinds from its bobbin by a suiificient length to allow the loop to leave the position of F ig. 10 and to take the' position of Fig. 11. ln Figs.' 8, 9 and 10, it is .further noted that the preceding loop runs very close to the curve of the guide comprised between the points 18 and 10. 'llo push the woot thread 13 forward or out of the guide,

'l preferably employ a reed which'is actuated by suitable means;

Fig.v 11 shows the warp thread which after having .formed the loop will now' return to the rear and will assume-after passing Fig. 13 which corresponds to that of Fig. 5. All the movements for ormingthe loop are now completed and a new loop maynow be formed.

Fig. 14 shows a yarn guide into which there are inserted two warp threads 5, one.

on either side; `ll thus obtain by thesame movements and with a single yarn guide two loops or two torsions at the same time around the woof thread, one to the right and the other to the left.

With my said device l am enabled to move the warp thread 5 in the direction opposite the side at which it was threaded. so that ll vobtain loops whose torsion is contrary to what the yarn guide will a'ord inta regulary manner. rlhis operation can be edected by hand or by,A means of a needle adapted to move the yarn, or by like means..

Flg. 16 shows a second position of the yarn f thus moved, and Fig. 17 shows the position in which the-warp has formed its triangular loop for the insertion of the Woof 3.

By this latter method lt am enabled tov `.interlace between the already-formed regu-l lar loops, the loops whose torsions have the opposite directionarelatively to the other d loops, thus producing a fabric having a varied appearance. v Figs. 18 and 19 show loops which have been regularly formed, i. e. according to y Figs. 4'to'ff'13, and Figs. 20 and 21 showl their position when completed.

Fig. 22 shows the loops -obtainedrby .the

Leraar? theftension which is given them; these loopsl may be mingled one at a time or by regular or irregular groups. l

Fig. 2t shows a second form of yarn guide in which the partabove Nthe aperture and slot is eliminated; the said guide devices may be' juxtaposed in suitable number 'according to the width of the fabric to be produced.

ll claim:

2. A stationary yarn guide in which warp and wett threads are to be looped together, comprising a body portion havingrspaced 'eyes designed to have a warp thread threaded eyes designed to have a warp thread threaded therethrough, said body portion. having an angular aperture the upper wall of said aperture being straight and the lower wall inclined', and said body portion having a straight guide slot communicating with said aperture. l 1 d d. A stationary yarn guide in which warp and weft threads are to be looped together,
