Description.

As seen in the accompanying drawings, the thread A is delivered from suitable spools over a rest bar or receiving member 8 of the herein-described carriage. The carriage consists of a skeleton frame having sides 9 spaced apart in parallel relation. The sides 9 are structurally united by crossbraces 10 and by tie rods 11 and 12. The rods 11 and 12, as shown best in Figs. 2 and 3 of the drawings, are each provided with a screw-thread operatively engaged by clamping nuts, 13 and 14, respectively, between which are clamped in service, reed-holders 15 and fingers 16, respectively. Both of these are laterally adjustable in opposite dil'GCtlOIlS: from each other. Said tie-rods are further provided with clamping nuts 17,

e which clamp rigidly the sides 9 to hold the same-in structural relation.

The thread A travels "over the carriage in the direction shown by the arrow a in Fig. 1' of the drawings. During its travel it is supported by the glass spreader bars 18 and 19, and rollers 20 and 21, the roller 21 being the delivering member of the device. Between the bars 18 and 19, the alternate threads are separated, one set of said threads passing below the bar 18 and above the bar 19, and the other set of threads passing above the bar 18 and below the bar 19. As shown best in Fig. 1 of the drawings, this forms what is known in the art as a cross. The cross is employed as the most efiiolent means for properly spacing the threads 1n their passage through the carriage for delivery over the roller 21 thereof.

It is found desirable in feeding the thread A to the reel from which it is re-wound to the loom drum, that .the width of the sections delivered by each operation of the carriage to the reel should have a predetermined compactness, and, further, that the edges of the sections being delivered should be prevented from thinning out, which would produce in the woven material what is known in the art as shiners. It is to prevent this that I use the guide fingers 16.

The fingers 16 are held on the tie rod 12 between the clamping nuts 14, said nuts frictionally engaging the end of the fingers with sufiicient force to prevent them being dragged by the thread A out of their upright active position. the nuts 14 is not sufficient, however, to prevent the tilting of the fingers 16 so that the ends thereof may be disposed below the plane of the thread A. This forms a convenient means for replacing any stray thread The engagement of i with a spread wider than the space between the fingers 16, which governs the delivery of the section of the thread being transferred to the reel. j 7

As seen best in Fig. 2 of the drawings, the

holders may be spread to accommodate reeds of different widths. To this end they are adjustable to'the proper places by simply running the adjacent nuts over, slidi the holders to the new position and again tightening the nuts. These reeds are of conventional construction and are produced in commerce to difi'erent widths. Heretofore the practice'has been to provide a carriage with a reed of maximum widthand when the section has been reduced, the center of the reed I alone has been employed. As a result of this practice, the center of the reed has had constant wear while the lateral portions have had relatively little wear. Consequently, the center of the reed is worn awaynecessitat- I ing the abandonment of the whole reed. This has proved of considerable loss to manufacturers. I

In the resent invention, where the holders 15 are a justa'ble and variable in their relative separation, a reed of a width correspondmg with the width of the section may be employed.- The result of this practice is that the reeds are worn evenly throughout their spread. As shown by the dotted lines in Fig. 1 of the drawings, the holders 15 and reed 22 carried'thereby may be rocked on the rod 11 to positions which facilitate the operations of crossing and knotting the threads.

By carrying the thread A in the-present invention above the rollers 20 and 21, the same is made accessible for manipulation by the operator. It also serves an additional and valued purpose in quickly detecting any broken threads which may result from the operation of the warping machinery. Also, any adhesion which would result in the twisting is quickly detected and readily corrected.
