pp ca on e pr en o To all whom 'it may concern:

Be it known that I, FREDERIC W. MOORE, a citizen of' the United States, residing at `Millbury, in the county. of Worcester and State of Massachusetts, have invented a new and useful Bobbin-Stripper for Weft-Replenishin Looms, of which` the following is a speci cation. y

This invention relates to weft-replenishing looms. In order that mispicks may be avoided in weavin cloth, ractically everybobbin which is use is' disc arged from the shuttle with more or less yarn thereon. In order that the bobbins may be used over again, this yarn is usually removed by hand. The o eration of removing it, consists of grasping t e art of the bobbin on which the arn is hel and striking the small end ofthe obbin on a bench or other stationary surface. This not only takes time, and in a large mill results in some little expense for labor, butit results in injury to the bobbins. In many cases, moreover, the yarn cannot be removedv in this way on account of the corrugations on the bobbin, and it has to be cut therefrom. This obviously injures the bobbins.

The principal object of this invention is to provide a practical means whereby the yarn will be unwound from the bobbins as they are discharged from thel shuttle. This is accomplished by mounting in some convenient position, preferably on the end of the frame, a rotating bobbin-stripper adapted to engage the end of the yarn which usually hangs from the bobbin when the same is discharged.

This bobbin-stripper rotates and winds the arn u on itself, removing it from the bobhis is done partly when the bobbin lis falling, and is com letedafter the bobbin reaches the can or otlier receptacle into which it is discharged. In orderto assist, in this o eration and retard the end of the yarn' so t at it may be more surely engaged by the.

provision of means whereby thebobbin is temporarily held' in. proper osition for the stripper to act, instead of fa ling at once to the bottom of the can.

Reference is to be had to the accom anying drawings which illustrate preferred orms of the invention, and in which l Figure 1 is a fragmentary elevation of the en'd of an automatic loom showing one form of stripper therefor.

artly in section of the improved can fo'r the bobbin. Fig. 2 is an end elevation partly in section of a ortion of the stripper showing how lit may e driven from the main shaft, andFig. 3 is a side elevation of another form in which the invention can be constructed.

Only a few parts of the loom are illustrated as it is obvious that the invention may be applied to ractically all forms 'of weft-rep enishing ooms for use in the textile industry,

Fig. 1 shows a portion of the end'frame'l,

the lay 11, and a part of the magazine or battery 12. On the lay is mounted a clearer cloth 13, while on the frame is mounted a bracket 14 car ing a spindle 15. This spindle is provide witha pulley 16 which by Fig. 1a is a side view means of a rope or belt 17 is operated from I the pulley 18 on the main shaft 19, but it is to be understood that it can be turned in any desired way. y

The spindle Vis of a convenient size and shape for the rece tion of a bobbin 20. Thisl bobbin may be o the ordinary character, or it may be provided withsa surface of cloth or other material to adapt it more readily to hold the yarn as it' passes it, but obviouslyafter one layer of yarn is wound upon it, the yarn itself will perform this function.

In operation the b obbins 21 are discharged from t e shuttle over the lay in such a manner that most ofthe ends of the yarn whichV remain upon .them will engage the clearer cloth. Thisholds the'ends back so that there will be little danger of the. yarn failing to'engage the bobbin 20, but in any event most of the yarn engages this bobbin, and as lit is rotated at a considerable speed, one or two turns of yarn will be wound upon it before the fall of the bobbin 21 can draw thek yarn beyond it. After this has been accomplished, the continued rotation of the spindle will wind the remainder of the yarn from the bobbin 21 either before or after it falls into the rece tacle 22. n

The evice can be constructed in many ways as I am aware without departing from the scope of the invention as expressed in the claims. One ofthese forms is shown in Fig. 3, in which instead of placing a bobbin on the spindle l5, a roll 23 is mounted thereon. On a frame 24 which has slotted arms 25, a second roller 26 is mounted. This roller moves by gravity along the slots in said arms into contact with the roller 23, and when the end of the yarn from a bobbin hasy once passed between the rollers it will be kept there long enough to be wound on the roller 23. In either event the pulley 16 is preferably provided with a guide 27 for holding it in position.

When the roller 23 or the bobbin 20 is filled with yarn' it can 'be removed and rel cause it to turn or wind up the yarn thereon,

placed by another or stripped in any desired way. f

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 difliculties the invention `preferably is carried out with a can having 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 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. They are retained on the shelf long enough for the strippe'r to Wind up enough yarn to secure a firm hold'.

It is to .be observed thatl there is an unobstructed space between the battery or magazine and the can, whereby the bobbin may drop down without hitting any surface to except the clearer-cloth and the stripper, the

y functions of which have-been explained.

In order that the shelf may be turned up to permit the bobbins tobe removed it 1s hinged to the can. It is also shown as adjusted so that it may be placed at the proper distance below the stripper to act efficiently with different kinds of bobbins and yarn. This may be accomplished in any desired way. In the drawings the shelf 1s adjustably connected with the can by screws 31 and thumb nuts 32, the former passing through slots 33 in the wall of the can.

While I have illustrated and described a preferred form of the invention7 I am aware that many modifications may be made therein by a skilled mechanic lwithout departing from the scope of the invention as expressed in the claims.

Having thus described my invention what I do claim .isz-

1. The combination with al weft replenishing loom, of means mounted-on the frame thereof for stripping yarn from the bobbins as they are discharged from the shuttle, and
