To all whom it may concern: Be it known that I, Fnnnnnie W. Moonn, Lt 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 \Vcftr- Replenishing Looms, of which the following is a s ecifieation.

his invention relates to weft-replenish ing looms. In order that inispieke may be avoided in weaving cloth, practically every b bbin which is used is discharged from-the shuttle with more or less yarn thereon. in order that the lJUblJltlS may be used over ifiaeinythis yarn. is usually ren'iovul l.)y"haud.

0 operation of removing it, eonsists o1- grasping the part of the bobbin on which the yarn is held and strllnng 'tl'iesinall end of the bobbin on a bench or other stationary Surface. This not only takes time. and in a5 are discharged from the shuttle. This is aecoinplishecl by mounting in some ronrenient position, preferably on the end of the frame, a rotating bobbin-stripper adapted to engage the end of the yarn whirl: usually hangs from the bobbin when the same is disohargged. '.l"his 'bobbin-stri per rotates and Winds the yarn upon iteell, remoi'iire it from the bobbin. This is done partly when the bobbin is Falling, and is romplet dafter the bobbin rem-hos the ran or other rooeplarliinto whieh it in dim-hargwl. in order to as in this operation and retard the end ol' vthe'yarn (-10 that it may be more ann-ly rugagmhby tho. bobbin slripp m'. a olearrr elolh Hi n'e'lorably mounted on too lay or H!

Another feature of this invention la thev provision of means whereby the bobbin is temporarily held in proper position for the stripper to net, instead of falling at once to the bottom of the can. i l V ltelereuee is to beh'ad to the iii-companying drawings which illustrate preferred forum of the ii'ivontiou, and in whieh- Figure l is a fragnuintaev elevation of the end of an automatic loom showing one term of strippertherefor.

This spindh-v is provided with a pH Ivy ill Wllll'll by means at a. rope or belt I? is operated l'rou'i the pulley IS on the, main shaft lb, but it is to be understood that it can be turned in any desired 'a v.

'lhe spindle is of a convenient size and.

shape for the rot-option of a bobbin 20. This bobbin may be of the ordinary (diameter or in any event; most of the yarn engages his bobbin, and as it 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 the yarn beyond it. After this has been accomplished, the contlnued rotation of the spindle will wind the rememder of the am from the bobbin 21 either before or :1 er it falls intothe receptacle 22.

The device can be constructed in many ways as I am aware without departing from the scope of the invention as expressed n the claims. One of these forms is shown n Fig. 3, in which instead of placing a bobbin on the spindle 15, a roll 23 is mountedthereon. On a frame 24 which has slotted arms 25, a second roller 26 is mounted. TlllS 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 has once assedbetween'the rollers it will be kept t ere long enough to be wound on the roller 23. In either event the pulley 16 is referably provided with aguide 27 for ho din it in position.

When t e roller 23 or the bobbin is filled with yarn it can be removed and replaced by another or stripped in any desired a'hen the bobbins are discharged into a dee can, some of them pass the stripper in sue 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 to permit the bobbins to be removed it ishingcd to the can. It is also shown as adjusted so that it may be placed at the proper distance below the stripper to act efiiciontly with different kinds of bobbins and yarn. This may be accomplished in any desired way. In the drawings the shelf is 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 invention, I am aware that many modifications may be made therein by a skilled mechanic, without departin from the scope of the invention as expressed in theclaims.
