To all whom it may concern:

lie it known that l. I'Ivmnn'r S. Woon, a t-itizen of the United States, residing at llopedole. in the county of Worcester and State of Massnehumttta, have invented an lmpmvement in l illing-Repleuishiug lloppent. of which the following dtmeriptton, m eonneetion with the accompanying drawings. in a s n-.eiliention, like letters on the trawin representing like parts.

The Invention to be hereinafter deserihet relates to tlllin replenishing lomuo, and more particular y to the filling carrier supplving menus employed therein Montana and purposea of the present invention are 'to provide an improved character of lllling eorrier supplying means, wherein the lllling earriere and the filling ends leading from oueh carriers may be pnua-rly eoutrolled. all as will more fully hereinafter appear in connection with the turom mnyiug drawings showing one form of means for earryiug vthe invention into prnetieal etl'eet.

In the tll'|t\\'ilt|ltt2-l"it{tll1 l is u. eentrnl aeetlouul view of one form of filling replenirtltittg tueelmniatu aml ita asmwiated partn emtualying 't'ttllltes of. the present invent ion: Fig. 2 ia top vien"lmllt'ing into the filling earrier mpplyiug menus or hopper; and Fig. 3 is a neetiottul view of the hopper. substantially on the line ;l--tl, Fig. .2.

The loom frame 1, the braeket 2 aecut'ed thereto hy auitable means, much as the bolts 8, the web 4, the stud shaft. 5 carried by said bracket, the transferrer arm ti mounted on the stud nhnft- 5, the a ring 7 for norumlly maintaining the trans errer arm 6 in raised position, the arm 8 to whieh the lateh carrier 0 is pivoted at 10, the luteh ll to be engaged at times by the banter on the lay the controller 12 oarried b the transverne a left 13 and engag ng the in 14 of the latch earrier to tosttion it or eoaction with the hunter w ten the filling is to be changed, may all be of any usual or well known construetion, or as fully set forth in detail in the engaging ace 18, may be as described in said prior application, and as they form no essengi'ior application, Serial No. 510,240, tiled I tiul part of the present invention, furthet detat description will be unnecessary. A! set forth in said a plieation, the transform amt 6 is provid with a pin 19 adapted when depressed to engage t ie arm 20 of I filling carrier positioner, normally held as in Fig. l by a spring 2!, and move the other portion 22 of said positioner over the filling carrier 23 next to be brought to transferring position, the said portion 22 of said posttioner being flexibly jointed at 24; and, when the transferrer art n 'is raised, as described in said application, to permit the spring 21- to act and cause the positionar tc move or force the ttlllu carrier neatto be transferred to transferr n3 position. As the end 22 of the poeitioner moves to engage the filling carrier next to be brought to transferrin position, it may sometimes happen that t to filling carrierwill retreat be ore the moving end 22 of the positioner. so that said end may not ride over and engage the filling carrier 28 on its rear portion. In such event, obviously, no fillingcarrier would be brought to transferring position when the transfe ee! returns from making a transfer. This action in more liable to occur when the hopper in nearly empty. To meetthis condition the present invention contemplates means for preventing back or retreating movement of the filling carrier next to be moved to transferring position, one form of whieh in heat indicated in Fir. l, whereimon the inner n'tion of the wal 25 of the hopper 26, is armed a shoulder or stop 27, ref; erably so disposed that when the end of the positioner rises to enga back of the next filling earrier in t ho par, .tht shoulder or atop 27 will prevent ekward or retreating movement of the filling car. rier. 'lhia shoulder or stop 27 ms be thetmsed to engage any au'itab a part 0 the carrier next to be unwed to tranaferrin tion. but in the present and profane: ortu ol'.the invention it is located to engage near the head end of the filli carrier, and is preferably formed as a ed part of the topper wall, though this may be otherwise if tesired. The hopper- 20 is preferablyformed of greater dimension from front to rear at its upper portion, to the end that titling carriers ma tbetnselevs in more than a single ortn staggered relation in said upper portion of the the filling ends lca in riera may be at its lower portion, the hopper is contracted to cause the filling carriers to move into single line formation as they approach transerring position. in the present embodiment cf the invention the hopper preferably comsnses the end portions 29 and forming a irecting channel-way for the carriers, said end portions being connected at the rear by a plate 31. At one end the hopper has a slot or openin 82 for the mar iage of the tilling ends whic i may be I to some point exterior of the hopper orpo a suitable take-u device to take up the al ck in the filling en a as the carrient more toward transferring positiop. In the form of opper shown the end porttomi- 29 imd'lit), re )referably-of cast metal having at r and ower web portions 88 and 34, but. 0 vionsly this characteristic of the hopper may be changed within the true scope of the present invention.

wlnp to the vibrations of the hopper caused iy the movin pmfs of the loom, from the carriers in the hopper throu h t in slot or opening 32 to a ta o-up or ot ier device are liable to become injured or weakened by the pounding or ru hing action thereon between the ti!) portion of the carrier and the metal wall 0 t to hopper, so that the filling ends are liable to break at this weakened )oint when any strain is placed thereon, as or instance when the carrier is transferred to the shuttle, or when the ahuttle is picked. 'l'he tilling ends extend in a downward and outward direction from the filling carriers eithci' to a take-up or other device, and, in the absence of any means to maintain proper tension ,on the fillin ends, tli'ose ends leading from the upper ling carriers are liable to become entangled with the tips of filling carriers below, so that such entangled filling end betaunes broken when the filhn carrier with which it is entangled is trans errcd to the shuttle. This may happen even where a take-up is used to act upon several of the filling ends for the purpose of taking up the slack as the carriers move toward transferposition, because more slack will occur ring in he ends leading from the upper carriers in' the hopper than from the can-icrs lower down in the hopper and non uently more nearly in horizontalrelation with the takeup. With these facts in mind the resent invention contemplates a control of tie filling ends themselves, regardless of whether they pass to a take-upor to a fixed int exterior of the hopper, to the end tha not only may they be protected from the pounding or rubbing action which is liable to weaken them and be held from entan 'lement with the tips of filling carriers be ow, but unwinding of the filling from the carprevented even where the filling ends are under the action of a take-up. One form of a eimnle expedient to these ends is shown by Figs. 2 and 3 of the draw mg, wherein the inner surface of the wall of the hopper adjacent the tip )ol'tions ofthe filling carriers 36 is provi ed with a" lining 37 of felt or other suitable yieldin v or fibrous material. The lining 37 is re erebly secured to the inner surface 0 the hopper b means of an adhesive, thoughany suits le means ma be employed, and is extended to a point su ciently remote from the end slot 32 to provide-a yielding cushion for the tip portions of the filling carriers, as indicated in Fig. 2' the construction being such that the filling ends 35, should the t between the tips of the carriers anti tii: lined wall of the hop )er adjacent thereto, will not be subject to the injurious pounding aml rubbing efiect, hereinbefore indicated. The lining 37 also preferably extends to or slightly over the slot 32 so that the filling, in passing from tho carriem to the take-up or other device, is held from sagging even thou h it becomes slack, the fibrous nature of tie lining acting as a holding or tension means, and the construction being such that tho filling ends leading from the upper carriers cannot become entangled with the tips of filling carriers below or the filling ends be unwound from the carriers by the action of 'the takenp, It will thus be seen that the lining 37 arts to control the filling ends, prevents them from becoming injured or weakened, holds or maintains a 'filhn end from dropping down ahead of the Ft lin carrier from which it extends, and provues a tension means to prevent unwinding of the filling from the carriers, a characteristic of special im mt'tatlt'o where a take-up is culploved, nu wil be obvious to tho.-e a illed in the art. At the lower portion the back wall of the hopper preferably curves inward, as at 38.

lg. 3, and is provided with it I'll) 39 over which the lining of felt or other yielding material extends to support the tip portions of the filling carriers and prevent such portions getting under the edge'of the front wall of the hopper. as they move toward transferring po-ition.

Rotation of the filling carriers in the hoph r is obviously objectionable, becausc'therceither too much slack is produced in the fi lin ends leading therefrom, or such filhn endsiieco the carriers and bro en. Experiment and practical experience has shown that when the base portions of filling carriers have an me wound u n the tip portions 0 its extended area or line of contact with the adjacent wall of the hopper, much rotation of thefllling carriers occurs, due t9 the loom vibration, but where such contact is reduced, less rotation is observable. With this fact in mind the present invention contemplates forming thc-inner surfaces of the, hOHPQl he fi mg walls adjacent the base portion of t carriers in such manner that onlv a single point of contact will oceur between the lat-e portton of a carrier am] said wall. In the present form of the invention the elnl portion 29 of the hopper is provided with a lhlnge 40. the inner surfaee 41 of which is tlared outwardl the construction heing sueh that. when a filling carrier having the usual metal rin on its base portion is re ting against llll surl'ure ll.onl v the emhnost ring 42 will he in-eontaet with the inner urface of hllltl wall. l.ilu-wi.-e the inner surface 43 of the haelt wall 11 is inclined or gl'mn't'tl as shown. and terminates with a head or tlan e 45. the construction heing such that only tlie end ring on the base of the filling carri r will t. ttaet with the surface 13.
