BOBBIN-STRIPPER FOR FIILING-REPLENISHING LOOMS.

Specification of Letters Patent. Patented Jan. 24, 1911.

I Application filed February 2, 1910. Serial No. 5413113.

duclien of novel and eifective means for stripping or unwinding the yarn from the bobbins discharged or ejected from the shuttle in a loom provided with filling replenishing mechanism, whereby the stripped yarn can be easily and quickly removed from time to time. i

' My invention is an improvement on the apparatus forming he subject matter of United States Patent No. 890,865 granted to F. V. Moore, June 16, 1908. In such patented apparatus the stripped yarn is collected on a receiving bobbin reniovably mounted on a rotatable spindle, and the yarn muss clings tightly thereto, sometimes mnlb ing. i hard to remove it, and as the smooth base surface of the receiving-bobbin will not catch the yarn from a discharged bobbin it is cuslmnury for the weaver to in-1t wind :1 layer of yarn upon lhe ruo-eirer. or the latter may be covered with cloth. \Yhcn covered with cloth the collected yarn mass clings so ti ghtly that it can only be removed by cutting. and if a layer of yarn is first wound upon the receiver the difficulty experienced in removing the yarn mass is not greatly diminished. In my present invention I orercome these objections by providing the rotatable spindle with a removable, tubular yarnreceiver of flexible material having a roughcued yarn-engaging surface, the receiver with lhefiyarn-mass thereon being readily slipped o the spindle, after which the receiver can be compressed or collapsed and drawn out of the yarn mass.

The novel features of my invention will be fully described in the snbjoined specification and particularly pointed out in the following claims.

Figure 1 is a front elevation of a portion of the filling replenishing side of an automatic loom with one embodiment of my in vention applied ihereto; Fig. 2 is a left hand side elevation of the bobbin stripper, with the driving means therefor indicated; Figyam-receiver, detached; Fig. 4 is an end VIQW of the yarn-receiver, compressed or the yarn-mass thereon.

In Fig. 1, 10 is the side frame of the loom, 11 is the l y, 1:? is a part of the megazine or battery for the reserve supply of bobbins, and 13 is a clearer cloth, mounted on the lay, all substantially as in the Moore patent referred to. On the loom side 10 below and in front. of the usual discharge chute or guide 14 I mount a bracket 15 which has a bearing 16 for :1 substantially horizontal shaft 17 extended through an opening in the loom-side and provided at its inner end with a pulley 18, while upon the outer end of the shaft is fixedly secured a conical spindle 19. The spindle is conveniently rotated by means of a belt or band 20 passed around the pulley 1S and driven from a pulley 21 on the main shaft 22 of the loom. Upon the spindle l9 1 removably mounta correspondingly tapered yarn-receiver R, Fig. 3, made of suitable flexible or compressible material and baring :1 roughened yarn-em gaging surface ll- This \'arn-recei\'er can be conveniently made of felt, heavy cloth, or other suitable material which will, when pushed onto the spindle l9 cling thereto, but which when removed may be readily collapsed or compressed by slightpressure.

The discharged bobbins B are ejected from the shuttle in such manner that the most of the ends of the yarn remaining upon such bobbins will engage the clearer cloth 13, holding the ends back, but the bobbin drops and carries the end across the yarnreceiver R, as shown in Figs. 1 and 2, and

the yarn-mass M, Fig. 4, is withdrawn from the soindle 19 and the receiver is compressed 3 is a perspective View of my improvfid remainder of the yarn upon the receiver as When a sufficient quantity of am has been collapsed to facilitate its withdrawal from r as the latter rotates its roughened surface R will catch the yarn and wind, it uponthe receiver.
