To all whom it may concern:

Be it known that l, FREDERIC VVLLLARD Moons, a citizen of the United States, residing at Millbury, ily the count-y of Worcester and State of ll'l'assachusetts, have invented a new'and useful Yarn-Stripper for lVef't-lieplenishing Looms, of which the following is a specification.

This invention relates to weft-replenishbin when the same is discharged. This yarn-stripper rotates and winds the yarn upon itself, removing from the bobbin. This isdone partly during. the fall of the bobbin, and is completed after the bobbin which it is discharged. l'norder t'o assist in this operation and retard the end of the yarn so that it may be more surely engaged by the bobbin stripper, a clearer cloth is preferably mounted on the lay or in some other convenient position. If the yarn engages this cloth, the fibers of the cloth become entangled to a slight extent with the threads of the yarn and hold the same back so that it will insure the yarn engaging the bobbin-stripper long` enough to get wound thereon in one or two turns, so that the fall of the bobbin will not release the yarn fromthe stripper. Means are also provided whereby the bobbin is temporarily held in proper position for the stripper to act, instead of-falling at once to the bottom of the can.

The improvement is illustrated in the accom an in vdrawings in which Figure 1 is a fragmentary elevation of the end of a weft-replenishing loom showing` the stripper. Fig. 2, is a side view partly in section of the for the discharged bobbins. Fie'. 3 is an end elevation partly in sect-ion of:` a portion of the stripper showing how it may be driven from the main shaft.

i Only a few parts of the loom are illustrated as the invention may be applied to practically all forms of weft-replenishlng looms.

Fig. 1 shows a' portion of the end frame 10, the lay 11, and a part of the magazlneor battery 12. On the lay is mounted a clearer `clot-h 13, while on the frame is mounted a bracket 14 carrying a spindle 15. This spindle is provided with a pulle 16 which by means of a rope or belt 17 1s operated from the pulley 18 on the-main shaft 19. but, it can be rotated in any desired way. A removable roll 23 is mounted on the s indle 15. On a frame 24 which has slotte arms 25, a second roller 26 is mounted. This roller moves byJ gravity along the slots in said arms into contact with theroller 23, and when the end ot the yarn from a bobbin has once passed between the rollers it will be kept there long enough to be wound bn the roller 23. The pulley 16 is preferably provided with a guide 27 for holding it in position. When the roller 23 is filled with yarn it ycan be removed endwise and replaced by another or stripped in any desired way.

This yarn-stripper is of special utility in the case of fine yarns and those of smooth finish. During the fall of the bobbin past the rollers 23, 26, the yarn is caught between them, and. is unwound from the bobbin by the conjoint act-ion of the driven roller 23, and the loose roller 26, which is frictionally driven from the roller 23, and separates therefrom as the yarn accumulates. This accumulation of the yarn is permitted by the separate mounting of the two rollers due to the slots in the arms 25. One or both the rollers 23, and 26, may be covered with rough cloth to .more readily grasp the yarn trailing from the falling bobbin.

When the bobbins are discharged into a deep can, some of them pass the stripper in such' a way that the yarn is not caught by it, and when a shallow can is used it soon fills up. In order to avoid both diliiculties the stripper is used with a can like that shown in Letters Patent of the UnitedStates, No. 890,865, June 1'6, 1908. This can has a shelf 30 extending from `one side nearly to the other so that as the bobbins are discharged on the shelf they are in proper position for the trailing end of the yarn to be engaged by the stripper and when the yarn unwinds the bobbins roll to the edge of the shelf and drop off. 'lhey are retained on the shelf long enough for lthe stripper to Wind up enoughyarn to secure a firm hold.

It 1s to be observed that there is an unobstructed space between the shuttle and the can, whereby the bobbin may drop down vwithout hitting any surface tocause it to '.bobbins falling 4trom the shuttle Within reach of the rotating rollers of the yarn stripper, so that the trailing ends of the threads pass in position to be caught by the rotating rollers. In order that the shelf may be turned up to permit the bobbins to be removed it is hinged to the can. It is also shownas adj usted so that it may be placed at the proper distance below the stripper to act efciently with different kinds of bobbins and yarn. This may be accomplished in an desired way. In the drawings ably connected With the can by screws 31 and thumb nuts 32, the former passing through slots 33 in the wall of the can.

I claim:

shuttle, said the shelf 1s adjust.

1. A weft replenishing loom having a yarn-stripper for removing the yarn from the bobblns as they are discharged from the shuttle, pair of rotating rollers located in the path of the yarn of the discharged bobbins.

2. A weft replenishing loom having vyarn-stripper for removing the yarn from the bobblns as they are discharged from the shuttle said yarn-stripper consisting of a pair of rotating rollers located in the path of the yarn of the discharged bobbins, said rollers being separably mounted so as to permit the accumulation of arn thereon.

3. A weft-replenishing oom having a yarn-stripper'for removing the yarn from the bobbins as they are discharged from .the yarn-stripper consisting of a pair of rotating rollers located inthe path of the yarn of the discharged bobbins, one of said rollers bein driven andthe other roller being separa l supported and rotated by the driven ro ler.

In witness whereof, I have hereunto signed 'l my name in the presence oftwo subscribing witnesses.
