To all whom it may concem:

Be it known that I, MELVIN L. STONE, of. Lowell, in

the county of Middlesex and State of Massachusetts,

have invented certain new and useful Improvements in Weft-Carriers for Automatic- Weft-Replenishing Looms, of which the following is a specification.

In modern automatic weft replenishing looms (such as the well-knownNortlu'op loom, which is sufi'lcieritly shown in United States Patent vNo. 529,940, Nov. 27, 1894) reserve. weft-carriers are supported in a suitable magazine, hopper or battery carried by the loorn, and

are transferred one by\one into the running shuttle 4 whenever the conditionof the weft renders replenishnie'nt' expedient or necessary. In such. looms" the automatic threading of the shuttle is-essentialjand this has heretofore been accomplished by the weav er securing the ends of the threads to. a suitableweft stud or holder by hand at the same time thatthe weft-carriers are placed in the battery. The usual battery of the Northrop loom is a rotary one and 'this weft stud or,

holder has been arranged .so as to rotate with the bat- ,tery, As a consequenceof this attachment' of the ends of the threads, when'a weft-carrier istransferred from the battery into the running shuttle the thread reels off-from the inserted'weft-carrier and the shuttle is antomatically threaded, as fully set forth in numerous I patents such as the Northrop-patent No. 454,810,.lune

23, 1 891. This usual way of securing the -ends of the weft-carrier's demands it shall be done at the loom itself and it also frcjuently results in misthreading when a -fresh weit-carrier is inserted into the shuttle,

owing to the carelessness of the weaver in leading the endloi the thre'adfrorn the weft-carrier in the battery to the weft-end holder along the pfre'scribed'and proper -In a. companion application -for-' Letters Patent of the United States filed April'l, 1904, Serial Number 201,059, 1 have set forth all improvement in automatic weft replenishing loomswhereby the duty of attention to the filling orweft has been taken away from the weaver and may be attended to away from the 100mand outside of the weave room.

a detachable magazine This improvement comprises of large capacity which may be filled with fresh carriers outside of the weave room and the magazine so filled need not be supplied to; the loom only at infrequent any convenient time and place, and the thread oi each weft-carrier is secured at its end to the attached weftend holder. The detachable magazine is filled with the welt-carriers with their attached weft-end holders, and the magazine is then placed upon the loom. At

the proper time in the operation of the loom the weftend holder is automatically removed from its weft.-'

carrier carrying the end of the thread with it which then un'reels [ron'i the carrier, thereby leaving the weft-carrier in condition to be transferred to the running shuttle, while 'theweft end holdcr'with the attached thread is maintained in a definite and pre-- I scribed place relative to the loom so that the danger of misthreading is minimized.

l The weft-carriers with the readily attachable and dcta'chable weft-end holders constitute the subject-matter :ofthe present application and certain embodiments of this improvement are illustrated in drawings, in which- Figure] is a plan view of aweft-carricr with a readily attachableand detachable welt-end holder appliedthereto. Fig. 2 is a longitudinal section of one endof the weft-carrier and the attached weft-end holder. Fig. .3 is a longitudinal section of the weft-end holder detached. Fig. 4 and Fig. 5 are opposite end views of the weft-end holder detached. Fig. this a cross-section I of the weft-end holder in a plane indicated by the line 66 in Fig. 4. Fig. 7 is a longitudinal section of a ing drawings is a wooden bobbin A which at its head or t the accompanying butt has peripheral rings a,. a, which enable it to' begrasped or held by'bobbin-holding jaws in the shuttle, as in the United States'patent of N orthrop, No. 454,807

.lune 23, 1891'. The weft-'carrierat its tip end is equipped with a readily attachable and detachable; I

weft-hmfholder B. This holder is provided with a I to fit over and outside the tip and of the weft-carrier, as

clearly shown in the drawings. This manner of detachably securing the Welt-end holder to the tip of the-- bobbin insurcs the maintenance oi the weft-end holder in place, and at'tho same time permits the weft-end holder to be easily attached to and detached from the bobbin. At its periphery the weft-end holder is pro vided with an open threading slot cl, preferably beveled at both mouths, as clearly shown in Figsl and 6.

yond the outer end of this threading-slot the wcitond holder has a stud e beveled on its inner face Where it joins the body of the weft-end holder, so as to form an annular groovo f. When the magazine is to be filled with Weft-carriers, one oi those we in place on each of the weft-carriers, end the end of the I thread is then passed through the threading slot (land is wrapped sever-Ll times around the outer stud 0, within the beveled groovef into which the thread sinks and is gripped sutliciently to nmintuin the thread securely ifl'plillt'lu The Wcibczu'riers thus equipped are then placed in the mnglihine and during the filling of the IllilflltZlllO, its transfer to thelooni and the grmter portion of the time which the hohhins occupy while on the loo'in, thescd (-tnchahle weft-end hold ers are main 1 All] ed in plfice Without any possibility ol coming off from the \VPft eurriers accidentally or otherwise, and Without {tllV possible oi wortnnitv for the thread to become i ll v detached from its weft-end holder.

As set forth in the accompanying and companion ap-- plication, at the appropriate time in the operation of the looni, the weft-end hold cr is automatically removed from the weft-carrier While still holding on to the end 01 the thread, so that the Weft-carrier freed ot the wei'tchannels when being fed anmmetically along in the loom on the way to the shuttle A modified wel'tmmrier and Weft-end holder isillnstinted in Fig. 7. in this case the l'(iht?il(l holdeirhas itsshzinkl) fitting within theonterciuloi the Weitwrnrrier A, which is provided with rifni etul bushing 24 to rccei e it.

The weft-end holdei' is provided at its outer end with s tapered elastic plug 26 of rubber, which furnishes beveled notches 27 on opposit 0 sides for the reception on d holding-for the end of the thread. Thisinodifiedcmmstruction is useful when the detachable magazine is employed in connection with the usual rotary battery of the Norhrop loom as set forth in my companion zipplica tion.

The form of the welt-carrier an d of the weft-end holder cam he modified rind changed in many other ways without depztrtingfrom the spirit of the present; inyenf t'ion.

It willbenoted thzitthis invention involves a newmethod of securing a weft-end. Instead of the old method of securing the welt-end to a permanent port of the loom, as in the Northrop loom, in accordance with the present method, the Weltcnd is secured to the detaehnhle wettend holder on the weft-carrier.

I claim as my invention .1. A weft'rzirrlcr for an :iutemiitic' weft replenishing loon having a detachable Weir-end holder.

A weft-carrier for an automatic weft-replenishing loom having at its tip and a detachable weft-end holder. '3. A we'ft-ca'rier for an automatic weftircplenlshing loom having a detachable weft-end holder provided with means for holding the end of a thread.

--t. A weft-carrier for an automatic wcft-replenlshing loom having at one end provisions for securing it to a' shuttle when automatically inserted therein, and having at its other end :1 detachable Weft-end holder.

A wcft-ein'rier foFun automatic weft rcplenishing loom having a weft-end holder to which the end of the thread on the carrier isfnst ene'd'f in witness whereof, I have hereunto signed my uinn'e in the presence of two suhs ibingwitnesses.
