SELVAGE-FORMING- MECHANISM FOR SHORT-WEFT LOOMS.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed March 7, 1904. Serial N 0. 196,822.

To all whom it may concern:

Be it known that I, FREDRIOK E. ARROU- QUIER, a citizen of the United States, residing at Westbrook, county of Cumberland, State of Maine, have invented an Improvement in Selvage Forming Mechanism for Short- Weft-Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to mechanism for forming what is known as the figure 8 selvage in looms for weaving fabrics wherein the weft is inserted in separate weft lengths, as for example in the formation of straw matting. In a prior application Serial No. 175,417, filed October 2, 1903, by me, I showed and described a mechanism for forming such a selvage automatically or by machinery. The present invention while producing the same product as that of my prior application does it in a different and simpler way. The mechanism of the present invention involves the use of rotating parts, and its action upon the straw is more gentle and yet is certain.

I have illustrated only such portions of a loom as are immediately connected with the selvage mechanism. This selvage mechanism is adapted for use in connection with any form of loom which feeds the weft in separate weft lengths. I do not desire, therefore, to be limited to the particular construction of loom.

In the drawings, Figure 1 represents a side elevation of a portion of a loom side and parts connected therewith; Fig. 2 represents in enlarged detail and partially in crosssection a portion of the breast-beam and lay with parts embodying my invention attached thereto; Fig. 3 represents in enlarged detail and in front elevation partly broken away one end of the lay with parts embodying my invention attached thereto; Fig. 3 represents in rear elevation a portion of the same mechanism shown in Fig. 3; Figslt, 5 and 6 represent in front elevation theweft end turner; F 7 and 8 illustrate in.perspective two positions of the tying plunger; 9 illustrates in perspective the weft end turner; Fig. 10 illustrates somewhat diagrammatically the selvage formed by means of this invention. Fig. 11 is a perspective view of the warp-guide and the end-turner showing the weft in the act of being turned.

Referring to Fig. 1, A represents one loom side in which is mounted the end of the shaft 0 carrying the warp-beam C and the ends of the rods 0 0 over which the warps pass, as shown at a, b, to the breast-beam c,- the end of the cam shaft A by means of the cams shown and the pitman A giving the proper movement to the lay-sword A carrying the lay A and the reed A*; the end of the cam shaft B carrying the cams B, B, for giving movement to the mechanism of this invention; the end of the tiebeam 104 carrying a bracket 108 upon which are pivoted levers operated by the cams B, B, hereinafter described. The mechanism for forming the shed is not illustrated except that the heddles are indicated and may be of any usual form. In Fig. 1 the shed is shown by means of the warps a, o, as open. The selvage cord 2 is shown as drawn from a spool or bobbin 2, through a tension device a around rods 0 and thence into the shed. By this independent mounting of the selvage cord I find that the tension can be better regulated and the cord better controlled, but I do not restrict myself to any particular means for holding or controlling the selvage cord prior to its passage into the shed. In looms of this character the weft lengths are usually fed alternately from opposite sides of the looms and but one end of each weft length is turned over or interlocked with the warps in some way to form the selvage. For this reason I have shown my invention as applied to both sides of the looms, but since its construction is the same on both sides it will be necessary to describe but one.

It is of course understood that by suitably timing the operation of the selvage mechanism it may operate upon the end of every other weft or any other desired repetition, but I have found that the best results are obtained by forming the figure 8 on alternate wefts on each side of the loom, as shown in Fig. 10 of the drawing.

While I have herein shown the mechanism for forming the selvage as mounted part upon the lay and part upon the breast-beam, I do not desire to limit myself to this position. of the parts, since any other position ;in which they would be able to secure their respective functions would be equally within the scope of my invention. I have also shown the mechanism arranged to turn the end of the weft up around the selvage cord and leave the loose end pointing in an upward direction, but it is obvious that this might be directly reversed and the selvage woven in the opposite direction. This would require but an obvious repositioning and retiming of the parts within the scope of my invention.

The mechanism for forming the selvage herein shown consists of two parts each having distinct operations to perform. In this respect my present invention resembles that shown and described in my prior application Serial No. 175,417, and I use the same terms end turner and tying plunger to describe these parts, although their construction, operation and functions differ considerably from those of my prior application. The end turner of the present invention is designed by a rotary motion to turn back the end of the weft around the selvage cord and down around the adjacent warp and then carry it outwardly under the said warp and selvage cord, and retain it in position for the action of the tying plunger. The tying plunger then passes down between the selvage and warp cord, catches the turnedover weft end and brings it up out between the warp and selvage cord so as to form the figure 8.

I will describe first the operation of the end turner. The function of this device is to turn the end of the weft, as above stated, and bring it into the position shown in Figs. 5 and 7 of the drawing. The end turner (J is shown as of cylindrical form provided on its exterior with gear teeth 0 and on its front edge with an eye 0 It is journaled over a correspondingly cylindrical warp guide B, which warp guide is fastened to the lay or reed or other similar portion of the loom, as by screws It with its face It projecting substantially into the plane of the reed. The face R of the warp guide R is provided with at least two warp guiding slots B one of which guides the selvage cord .2, and the other of which guides the adjacent warp Z) used in the formation of the selvage. It is of course obvious that the selvage might include, if desired, additional warps, but the drawing illustrates the preferred form. The end turner is rotated by means of the engagement of a reciprocating rack-bar O sliding in a suitable way 0, in the lay- The rack-bar 0 may be operated in one direction by a spring 0 and is operated in the other direction from the cam B, through the lever 0 and the connecting rod 0", an additional spring 0 being provided for holding the lever O in contact with the cam B. The cam-shaft B carrying the cams B, B, is arranged to rotate in a direction opposite to the cam-shaft A and when the selvage is formed on alternate ends of the wefts, as herein illustrated, the

shaft B has one rotation to every two rotations of the shaft A The weft is fed into the shed with the lay in its backward position through the funnel S by means of the feed rolls T, and is cut off to proper length all by means not necessary here to describe. WVhile the weft is being fed into position the end turner at the side of the loom upon. which the end of the weft is to be turned is in the position shown in Figs. 3 and 4 of the drawings, so that the weft passes through the eye 0 while at the other side of the loom if the weft is not to be turned the end turner is in the position shown in Fig. 6 with its eye 0* above and out of the path of the weft. Upon the forward motion of the lay the cam B acts to turn the end turner from the position shown in Fig. 4 to the position shown in Fig. 5, carrying the end of the weft back over the selvage cord, down around the adjacent warp, and leaving the end projecting out under both the selvage cord and the warp, as in Figs. 5 and 7 and in this position the lay beats up. Meanwhile the end turner at the other side of the loom if the end of the weft is not to be there turned remains in the position shown in Fig. 6. As the lay returns from the beat up the tying plunger hereinafter to be described operates to pull up the turned end of the weft between the warp and the selvage, as shown in Fig. 8, and immediately thereafter the end turner if the next weft is not to have its end turned thereby, passes back to the position shown in Fig. 6, and remains in this position while a corresponding series of operations takes place at the opposite side of the loom. I'Vhile I have thus described a particular way of operating the end turner I do not desire to be limited to the particular mechanism, or to the particular shape or construction or mode of operation of any of the parts described. I believe I am the first to make the figure 8 selvage automatically or by machinery, and outside of what is shown in my prior application Serial No. 17 5,417 I do not desire to be limited or restricted in any way. The feature of the present invention is the provision of mechanism by which the end of the weft is carried entirely around the selvage cord and the adjacent warp, and held with its end projecting under both so that the tying plunger can pass between the selvage cord and the warp and draw the weft end up therethrough. It is obvious that this may be effected by various forms of mechanism, other than that shown and described.

I will now refer to the operation of the tying plunger. This is shown as a hookshaped device P, with a barb I at its end, and pivoted at P upon the breast-beam. It is shown as operated in one direction by a spring P and in the opposite direction by a rod 1? connecting it with a lever (concealed in the lever O in Fig. 1) operated by the cam B. The operation of this device is very simple. When the jog p in the cam B rides over the operating lever the spring P throws the tying plunger down. At this time the lay is just returning from beat up with the weft held by the end turner in the position shown in full lines in Fig. 5 of the drawing. The cam B then acts to return the tying plunger P to the position shown in Fig.2, the barb P drawing the weft end up between the selvage cord and warp, as shown in Fig. 8. WVhile I have thus de scribed the particular form of mechanism for the tying plunger, it is obvious that it may be constructed and operated in various ways, and at various times. The only function of the device is after the weft has been placed in the position shown in Fig. 5 at a predetermined time to pass down between the selvage cord and warp, catch the weft end and draw it up between the selvage cord and warp, and save as restricted by the disclosure of my prior application Serial No. 175,417, I do not desire to limit myself in any way to the construction or the opera tion of the parts shown herein.

In the following claims I have for convenience used the terms up, down, upward, downward, over, under, etc., in connection with the movements of the mechanism with respect to the shed, but it is to be understood that these terms are relative only for the mechanism is equally adapted to be placed in a position opposite that shown with respect to the shed and to operate accordingly in a reverse manner. Also when I have used the term eye in connection with the end turner I do not desire to be limited to a closed aperture in the end turner through which the weft is passed, since it is obvious that the effective portion of the eye is only the wall which acts against the weft to turn its end around.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is
