' To all whom t may concern:

Be it known that I, Louis S. BURBANK, a citizen of the United States, and a resident of Ludlow, in the county of Hampden and State of Massachusetts, have invented an Improvement in Automatic Filling- Changing Looms, of which.A the following removed by replacing the exhausted shuttle with another shuttle. Y

ln order that the principle of the invention may be readily understood, I have disclosed a single embodiment thereof Vin the accompanying drawings, wherein- Figure 1 is a front elevation of the right hand end of a loom constructed in accordance with my invention;

Fig. 2 is an end elevation thereof;

Fig. 3 is an enlarged end elevation of the take-up mechanism;

F ig. 4f is a plan View of the right hand end of the loom;

Fig. 5 is a front elevation of the construction shown in Fig. 4;

Fig. 6 is a detail showing a portion of the feeler mechanism; i

Fig'. 7 is a vertical section of the construction shown in Fig. 6;

Fig. 8 .is an end elevation of the mechanisln shown in-Fig. 4; n

Fig. 9 is.v a front elevation, partially in vertical section, of the lay and parts adjacent thereto;

Figs. 10 and 11 are vertical sections respectively on the lines 10-10 and 11-11 of Fig. 9;

Fig. 12 is an end elevation partially in vertical section of the lower portion of the loom;

Fig. 13 is a plan View of the construction shown in Fig. 12;

Fig. 14 is a front elevation, partially in vertical section, of the construction shown in Fig. 12;

Fig. 15 is a view similar to Fig. 14, but of a portion only of the mechanism shown therein and illustrating the parts differently positioned;

Fig. 16 is a View similar t0 Fig. 12, but

upon a larger Vscale and showing only a part of the mechanism'shown in the latter figure;

Fig. 17 is a detail in plan and longitudinal section of a portionv of the feeler mechanism vadapted to `a bobbinless or coreless filling package in the shuttle;

Fig. 18 is a diagram illustrating the throw of the shuttle under different conditions; and

Fig. 19 is an end elevation of the lower part of the loom, but showing a modified l construction.

The loom of my invention may be used in various relations and for weaving various kinds of material. It is, however, so far as the disclosed embodimentl is concerned, particularly adapted for weaving jute-and other coarse and heavy fibers in the manufacture of gunny bagging.

In carrying out my invention the filling may be replenished in any suitable manner,

.but preferably by .replacing the exhausted shuttle with a refilled shuttle. The filling supply may be in any suitable form or package, but in that type of loom to which I have particularly applied my invention, the filling supply is in the form of a bobbinless cop or package of yarn coiled into a gener ally cylindrical mass having preferably more or less tapering ends, and forced into the shuttle which may 'be of large size.

In an ordinary loom there is a brief time in the lay stroke when both boxes may be emptied of the shuttle and still not interfere with the picking or dagger actions of the loom, and the loom will run on uninterruptedly if the shuttle be restored to its original place at or before the expiration of such time. The limits of the period referred to are the passing of the frogs by the daggers on the forward stroke of the lay and the beginning of the picking action on the following back stroke of the lay.

If the filling motion be suspended for one pick or if there be no filling motion on the loom, the empty shuttle may be removed from its box during the period referred to and a refilled shuttle may be inserted in the opposite box. Such reflledshuttle may be put into the opposite box by sending it into the shed or without passing it through the shed provided the action of the filling motion be suspended temporarily and the takeup mechanism be similarly suspended.

The disclosed embodiment of my invention is based upon this general principle of l i2, vand the connecting rode 4r1 AS Shown moet clearly in Figs.

in carrying out my invention, l" incieralaly provide a so-called transiter red l lneriaontally mennted in suitable bearings generally indicated at i9 in the framing ci tire leorn and adapted to receive lootli axial movement and a rotative movement at tlie time when tlie transfer or elia-nge of shuttles is te ce eiiectede is in ne vviee particularly to t'ne dra/vvtlie leem are represented e iront e ranlr tliereei at 5 lli and l5, tlie transfer rod l is provided with a laraclret iiaving rolls 2i, 2l mounted thereon and suitably spaced for the reception oi a lever arm 22 mounted upon a slaat-t 23 andadapted made :tast with respec tliereto, so tliat in the rocking movement oi tire said sliait, axial movement may loe imparted to the transfer red i8. The sliatt 23 is constantly recited but the lever arm 22 is only periodically made iast with said rock slia'i't and hence only periedically,-and that in the event of breakage or suloetantial or complete exhaustion of tire @lling-is axial or rotative movement imparted 4to tine traneer red le.,

Fast upon said rock shaft 23 is an arm 2li provided with a roll 25 adapted te enter agroove in tlie cam 26 upon the cani (i, vvliereby a constant rocking inovenient ie iinparted te said slia't 23.,

Since tlie bracket- 27 is fast ngen said sliait, the interengageinent ci the toetli 3f. and notcli 39 will temporarily render alle lever arm 22 :fast upon the sliait 23, and hence sail lever anni `@vill partake of the rocking movement-ei said shaft and thereby at suoli times impart axial or longitudinal movement to the transfer rod i8.

in accordance vvitli my invention, l provide ineens under the control o' the feeler mechanism, and also, ii desired and as herein shown, under the control ofi the iilling "fork, vvliereby tlie parte are temporarily connected vand axial movement is imparted to said transfer rod i8., Y

While this result may 'be eectedin any suitable manner, liliave in the Ipresent eina bodiinent ci tlie invention shown tl'ie described movements ci the transfer rod 18 as controlled by a eeler 33, which ie adapted te enter an opening 3e in the iront Wall of the shuttle loon and to feel through an opening in the shuttle for the -illing 36 therein. ln the' disclosed embodiment of my invention, such filling is Wound in a coil or general cylindrical package, lout Without a core, and is' forced or packed into the cavity 37 of the shuttle, such cavity generally having concaved or taperedends, as indicated at 38 in llig. 17. The yarn is built up in nested conical layers into a coreless package, the tips oi the said-layers pointing to the right in Fig. 17, andthe yarn feeds 0Hj niet reni the lett hand end of the shuttle, viewing said gure, and the ieeler makes its indicating. movement -past the base of a conical layer near the tip of the package. Such yarn package may be held in placel in the shuttle merely by friction or if desired by a strip 38 secured to the shuttle or in rlChe filling is gradually Withdrawn from the shuttle beginning from the left hand end thereof, viewing Fig. 17, and the ieeler 33 in feeling vier the filling is prevented from entering the Shuttle until the iilling has been exhausted to a predetermined extent and substantially to the extent indicated in said figure. When the filling has been exhausted to the extent there indicated, the feeler is permitted to enter past the edge or shoulder 39 of the remaining lling and therefore is permitted to maire a relatively prolonged movement -inte tlie shuttle past seid edge or shoulder lll 39, This permits more certain inovenient I of the parts controlled by saidfeeler. S0`

far as I am aware, I am the first to employ a coreless package in the shuttle and to employ a feeler to enter the shuttle and feel for such package and to act upon such indication. As previously stated, however, my invention in all aspects thereof is not limited to the -employment of such a type of feeler, nor to a shuttle having a coreless package, although I obtain marked advantagesin the use thereof. 'Ihe feeler may be of any suitable type, and my invention is not limited to that form or character of feeler herein shown. In accordance with myv invention, the feeler feels for the receding or basal ed e of the filling package preferabl at or su stantially at the inner surface o the wall of the shuttle, and when the edge or basal por'- tion is found or felt, then the feeler moves inwardly in effecting replenishment or functioning. Such inward movement is preferably a relatively great one, but my invention is not limited to such relatively great movement, inasmuch as so farV as I am aware, I am the first to effect replenishment of a shuttle carrying a coreless package where the feeler feels for the basal or edge portion of the package. My invention is not limited to a construction wherein the feeler moves or functionsl when theprecise or actual edge or base of a layer is reached or felt, because the feeler may function just before the precise edge is reached as by crowding inward boss .40 upon a sleeve 41 loosely mounted upon a pinv or stud 42 and secured in such position by a set screw 43. The said pin or stud 42 is mounted in any convenient position upon the lay of the loom and preferably as indicated in Fig. 9. Between the pin or stud 42 and the outer sleeve 41 is an inner sleeve 44 also loose upon said pin or stud and having extending therefrom a lng 45 ,having therein an opening 46 into which takes the hooked end 47 of a link or wire 48, the opposite or inner end of which is pivotally connected at 49 to the upper arm 50 of a lever 51 pivoted at 52 upon a stud extending from the loom frame. The lower arm 53 of said lever 51 is pivotally connected to a so-called equalizer rod 54, which is connected substantially midlength thereof to a link 55, itself pivotally connected at 56 to a bell crank lever 57 pivoted at 58 upon lines in Fig. 16, and also a cam 80.

a stud projecting from a bracket '59 upon the loom frame. The arm 60 of said bell crank lever 57 is suitably connected to the upper end of a so-called feeler rod 61 here shown as having nuts 62 between which'is received the end of said arm 60. The said feeler rod 61 extends downwardlyv as indicated in Figs. 14, 16, etc., and is guidedin an arm or lbracket 63 fast upon the rocker shaft 10 of the lay sword. If desired, the lower end of said feeler rod 61 may pass through an opening in a lug or projection 64 laterally extending from said arm or bracket 63 and into proximity to the upper end of an adjustable stop 65 upon a bracket 66 suitably supported upon the looror other base.

Viewing Figs. 9, 16, 17, etc., it will .be evident that as the lay moves backward, rocking about the shaft 10 thereof, the feeler rod 461 moving with the lay Will engage the top of the adjustable stop 65 and during the further movement of the lay will be lifted by reason of such lengagement with the adjustable stop 65 and hence will through the described connections shown F ig. 9, move the feeler 33 out of or away from the shuttle. The movement of the feeler rod' 61' without entry of the feeler into the. shuttle is permitted because of the inner and outer sockets 41, 4-4 by which the feeler is supported. 95 Said sockets have ears 67, 68 indicated most clearly in Fig. 6 and connected by a coil spring 69.

As shown most clearly in Fig. .16, the feeler rod 61 passes through an opening 70 100 in a pawl 71 mounted upon a stud 7 2 upon the loom frame. Between said pawl and the upper end of the bracket 63 is a coil spring 64 tending constantly to depress sald feeler rod 61 and below said pawl 71 is a 105 collar 73 to hold the pawl into proper position. The downward movement of the feeler rod 61 permits the tooth 74 of said pawl lto engage one of the teeth 7 5 upon a ratchet 76 frictionally held upon a stud or short 110 shaft 77 as most clearly indicated in Fig.

12. In order to hold said ratchet frictionally and to revent over movement thereof, I have hereln represented a friction clamp 78 as embracing and frictionally holding 115 the stud or short shaft 77. As most clearly indicated in Fig. 14, the shaft 7 7 is provided not only with the ratchet 76 but with an adjacent ratchet 78, a cam 79 indicated in full 20 When the lay'moves forward and the filling is in the shuttle, the feeler strikes the filling and this Contact lifts the finger 71 before its point 74 passes the ratchet tooth 7 5, and thus avoids a transfer. This is the 125 normal action of the feeler. If however there be no filling in the shuttle, the feeler enters the shuttle and consequently affects the lowering of the rod 61 a little, thereby delaying the lifting of the finger 71 suHi- 130 ciently to ellovv its 'point to engage the seid reteliet tooth 75 and thus eeuse e. treneter. The nger 271 lifts some time on the forward stroke of the is lifted by the illing it is lifted betere it reaches the tooth 75, but it' it is lifted eiter the eeler has entered shuttle it strike the tooth 75 end turns the ratchet, thus initiating the ratchet action.

lt will loe-understood from the foregoing that the eeler is forced positively out the shuttle when the ley rocks beokvverd and the rod d1 strilesthe conteet 65. Then when the ley roclrs oriverd the rod til drops of its own Weight or it be assisted by the spring Se. its it deesse it brings? the i'eeler into the shuttle et the proper Jinfie, controlled by theA adjustment of the stop 65. Then if the eeler strikes the filling the result is that hereinbesore describeda may `be steted that the spring 69 yields when the eelerv is positively orced out or the si uttle ege-inst the iieeler action hereinbetore described, by the contest ot the 15e with the lez-teli 154i".x lbet is to eey, eiter the eeler hes done its Worlr must be pushed out ot the shuttle to ellovv the to pess out of the box in trensierrniG The engagement of the pevflp 1 'with e tooth ot the retehet 76 eects e. partiel turning of the letter and permits the end of en operating pevvl 81 to' engage e tooth olli the adj ecent ratchet end also permits the tooth or extremity oic the holding pavvl 82 to engege with e tooth ci tbe rst-@het 76 end prevent beclr movement thereof. The rotation et the ratchet 'IS and consequently or' the short shalt 7'? effects e movement of partiel rotetion or the cam du, end brings the seme beneath end into engagement with e downvverd projection 83 upon e pevvl del shown most clearly Fig. 15 and which' es indicated in Figs. 12 end 111 extends benen-th the lower end of e pin 85. The pin 85 is guided in the bracket 27 end et its upper end takes under the pivoted latch 29 and li'lts the seme into enge-gement vvith the tooth 31, thereby through the previously described connections rendering the lever erm 22 periodically fest with the constantly rocking sheit 23, end thus imparts longitudinal movement or the transfer rod.

Referring rst to the eeler rod 61 end to the timing of the movements thereof end oi: the related parte, l point out that in the preferable operation of parts end es disclosed herein, when the ley is beck (that is, sway' from the Weaver) the bottoni end of the eeler rod 61 comes in contact with the adjustable stop 65 e little before the shuttle has lett the shuttle box end forces the eeler out of the shuttle, so that when the ley is clear bach', the eeler is clear out of the shuttle, Conversely when the ley stette orvverd (on the strolre tvliioli brings ir shuttle,

e. the one nest following), the 'eeler starts invverd end is timed by the adjustable Stop to the shuttle just eter the arriva-l et the seme. The eeler moving in ell the time, however, touelies the illing in the shuttle eter which its urther inward movenient is errested by this eontect. Consequently the ringer 71, shown most clearly` in Figs, 1, 2 end 16, eennot descend ier enough to its point "Z'lf with the ratchet tooth Pw5, hence no transfer occurs., Should, however, the ifeeler go into the shuttle, e transfer would taire pleee, When the feeler striltes the lling in the shuttle, this etlects e lifting or' the eelerrod @1l-away from the adjustable stop 65 et the time olf no transfor. fit the tune of transfer, however, the eeler rod d1 is still lifted, though a little e" er, but this lifting is eiiected by the linger 1 in conte-ct with the retehet '275.

ln this or in any other suiteble ine-nner, the Jieeler controls the movement of the transfer rod which es herein described efrects the transfer of the new shuttle and the reception ot the discarded shuttle.

l have stated that the movement of the eeler rod 61 mey be edected either by the ieeler or by the iilling iorlr. ln Figs. 9,

and 11, l have indicated one form of ineens whereby the lling fork will also be ceusel to operate the eeler rod 61 in the event oi breakage of the lling. For that purpose l have herein represented the illing toria et 86 es pivoted et 87 in the usuel menner end having rigid therewith e leterelly err-tending lug 87 connected by e link 88 with the erm 89 of e bell crank lever 90, the lovver erm 91 whereof is connected es indiceted in Fig. 110 to the rod 54C. 'lhe said rod 5ft, as previously stated, is connected by the equalizer link to the eeler rod 61. Thus throueh the described connection, either the lling fork or the eeler may be employed to initiete the shuttle transfer.

lt is usually importent that during shuttle transfer, the take-up should be suspended. For that purpose l have provided the cem 79 heretofore described end which, es indicated most clearly in Fig. 16, engages and rocks e lever 92 pivoted et 93 and et its lower end connected by e. link 9e to e lever 95 pivoted et 96 and having at its upper end a. shield QTedepted to be interposed beneeth the take-up pevvl 98 shown most clearly in Fig. 3.

Any suitable take-up mechanism may of course be employed. Herein for the purpose l have provided e take-up roll 99 driven from a. roll 100, the gear'wheel 101 of Which is driven bye pinion 102 upon the short shaft 96. Fest upon'said shaft' 96 is e ratchet 103 with which engages the psv/'l 98, thereby to drive the seme and to rotetethe talee-up. rlllie teilte-up pevvl 98 is mounted upon en 1021, to which is reageer pivotally connected a link 105 operated from the loom in any usual manner, not herein necessary to explain. By interposing in the described manner the shield 97 beneath the pawl 98, the take-up' is temporarily suspended. The ratchet 103 is held from backward'movement by the pawl 106.

1n the manner described, or in any other suitable manner longitudinal movement is impartedto the transfer rod 18. 1n order to impart a movement of rotation thereto', 1 may employ any suitable means but preferably I mount on said rod as most clearly indicated in Fig. 8, an arm 107 having thereona roll 108 adapted to take against a spiral or other suitably shaped cam 109 upon the under side of the breast beam. .The shape of saidv cam is such that the axial movement of said transfer rod causes a corresponding movement of the roll 108 along the cam 109, and the latter imparts a suitable movement of partial rotation to the said transfer rod. The return movement of the transfer rod 18 is effected through the coiled spring 110 interposed between the frame of the lay and the bracket 111 fast upon the said transfer rod.

Fast upon and upwardly extending from the transfer rod 18 are the arms 111, 112 each having a hub 113 secured to the transfer rod by set screw 114. rThe upper ends of said arms 111, 112 are providedwith longitudinally extending sleeves 115 wherein is mounted for axial or sliding movement a guide rod 116 which as most clearly shown in Fig. 4. is provided with a keyway 117 to prevent rotative movement thereof. On the outer end of said rod 116 is a picker member 118 by which the new or replenishing shuttle 17is thrown into or over the shed and thence into the opposite box of the loom. 4Return movement is imparted tothe rod 116 by a coiled spring 119 shown most clearly'in Fig. 4." i

Secured to the arms 111 and 112 and inwardly extending therefrom are arms or lugs-which carry a receptacle, box or shelf adapted not only to .support the new orreplenishing'shuttle but also the exhausted shuttle. While any suitable means may be provided for the purpose 1 have herein represented as secured to said lugs an auxiliary or transfer box 121 having a front wall 122 and a rear wall 123 between which said new shuttle is received. 1 have herein indicated the. said box 121 as occupying an inclined relation in a substantially horizontal plane, thereby permitting the replenishing shuttle to be thrown into or above the shed at such an inclination that it nds its way into the opposite box and without interfering with the outcoming or discharged shuttle 16. The said transfer box 121 is provided with a laterally extending fin or shelf 124, of such form that when the transfer box 121 is moved into the position shown in Fig. 4, said 1in or shelf 124 will receive thereon the discharged shuttle 16. The said 1in or shelf 124 is provided at its inner end with a box-like member 125 having therein an impact member 126 for the shuttle 16. r1`he said discarded shuttle 16 may readily be removed by hand from the said iin or shelf, but 1 prefer to have the recoil of spring 110 throw it out.

The construction and relation of parts are such that the filling feeler will be out of the shuttle at the time of s uttle flight or when the lay is back of the center and will be in feelingl position during the rest of the time.-

rlhe amount of filling to be held in reserve in order to complete the-pick will depend upon the nature of the fabric being woven; Inasmuch as 'the mechanism herein shown operates quickly enough to function upon the immediate lay stroke, ll prefer when weaving gunny fabrics to place the feeler on the same so I side of the loom from which the empty f shuttle is expelled, and then allow the shuttle to be completely exhausted before transfer, or I may reserve one full pick according to the nature of the fabric.

I provide means to prevent the feeler from acting or functioning when the shuttle is on the opposite side of the loom from that at which the feeler is located or otherwise the feeler would act in the absence vof a shuttle, and by moving downward the feeler rod 6-1 would cause the replenishin mechanism to function. r1`herefor,e I prov1de what 1 term an alternating mechanism to prevent the functioning` of the feelerl when the shuttle is not in the box at that side of the loom. While for this purpose 1 may provide any suitable means, l have in Fig. 12 represented the camshaft 6 'as having thereon a cam 127 adapted to Vact upon the end 128 of a Vlever arm 129 pivoted at 130 upon a standl ardy or bracket 131. Rigidwith the'lever arm-129 is a downwardly extending arm indicated in dotted lines at 132 in Fig. 12, and havingI an enlargement 133 adapted to engage the lower end 134 of a lever-arm 135 rigid with the operating pawl 81, shown most clearly in Fig. 16. The action of said cam 127 therefore is to hold the feeler from functioning whenever the shuttle is not in the box at the right hand side of the loom, by preventing-.the operating pawl 74 (Fig. 16) from imparting rotative movement to the cams 79 and 80.

1n Fig. 19,. 'have'shown a slightly modied form of my invention.

ine-ieri the number of teeth and size and shape thereof and the lposition of the cams, l am enabled to match the pick on any ordinary shade, since the yempty shuttle can be sent back and forth and the cam mechanism may be sent for transfer Where the original shed opens. ln the case of odd shades, l may supply enough teeth to double the cycle, thus bringing the shuttle back to the battery end of an evennumber, stopping the take-up in the meanwhile and starting in the nevi7 shuttle on the original pick.

Certain features of Amy invention are adapted to a loom wherein the filling is carried u on a bobbin in the shuttle or other That is, although.

suitab e core or support. l have disclosedand preferably employ a coreless package composed-of nested cones, past the base of one-of which the feeler finally moves invv its indicating movement, my invention is not restricted thereto so-far as many features of the invention are concerned.

`With respect tothe transfer rod 18 and the box 121, it is pintedout that the recovery of said rod and boxwill in practice develop a motion suiicient to eject the exhausted shuttle into a receptacle, and therefore will reduce the tension required by the weaver. 4

rThe rod 116 does not in the ordinary sense serve to pick the shuttle out, but together with the spring 119 serves as' a yielding motion to delay the time of the shuttles departure from its transfer box, so that the lay will have more time to open its shed in order that the shuttle may enter therein.

That is to say, the new shuttle would be pickedout from its transfer box if the rod 116 and the spring 119 were omitted, but it would leave the same at the same time that the outcoming shuttle leaves the shuttle box of the loom which is "ntentionally on the fiat shed. rlhe spring 19, therefore, serves to delay slightly the introduction of the new shuttle. j I

Within the broad 'scope and purpose of my invention, ,l may instead of employing a spare shuttle, employ a battery to support.

lling carriers of any suitable type and construction, or l may employ a battery to support a plurality of shuttles. llt will be understood from the foregoing description that if there be no shuttle in the transfer box or in the battery to replace the outcoming or discharged shuttle, the loom will at once stop on the dagger action. flhe loom will automatically stop either from the 4exhausted shuttle o'r from ya broken weft thread because either of them will call for a transfer. lf l employ a battery tosupport shuttles or weft carriers, l will employ a suitable thread holder, the thread extending from each shuttle or filling carrier to some part of the battery or loom, so as to start the Shuttle filling action. Such thread holder is preferably in the form of a clamp located either at the top end of thearm 112 as shown in Fig. 5, or it may be located near the opposite selvage of the cloth in case the new shuttle does not enter the shed half way across. ln such latter case, yarn would be saved. The purpose -of employing a clamp is to allow the thread to draw out therefrom as the cloth feeds along.

So far as l am aware, I am the first to provide a jute or similar heavy weft' loom having a coreless package in the running shuttle, with means to effect replenishment of the filling, and desire to claim the same broadly. While in the disclosed embodiment of my invention, I have illustrated replenishment by supplying a new shuttle, I may le'ect replenishment by inserting a new filling package into the running shuttle. l may, however, feel for the filling on a regular bobbin.

While l have herein disclosed means for supplying a new shuttle and means for discharging the exhausted shuttle, it is to 'be Having thus described one illustrative4 embodiment of my invention, I desire it to be understood that although specific terms are employed, they are usedin a generic and descriptive sense and not for purposes of limitation, the scope of the inventionbeing set forth in the following claims.

Claims:

1. A weft replenishjng, loom having a support for a spare shuttle at one side ofthe loom, means to pick that spare shuttle from its support across the loom,thereby bringing itinto play, and means to discharge the exhausted shuttle in a direction longitudinally of the lay and of the shuttle from the shuttle box atl that side of the loom where the spa-re shuttle is supported andto receive the said discharge exhausted shuttle at said side of the loom where the spare shuttle is supported, whereby the exhausted shuttle 3. A weft .replenishing loom having at l one side thereof a transfer box, means to move said box into a substantially horishuttle, supplemental picker means to discharge the exhausted shuttle into said receiving means therefor, and means controlled by the condition of the filling to govern 'the action of said supplemental picker means.

20. A weft replenishing loom having a lshuttle to receive a coreless package of lilling, means exterior to said package to hold the diminishing filling package in position in the shuttle until substantial exhaustion, and means mounted exteriorly of the shuttle to feel for and to contact with said filling in the shuttle.

2l. A weft replenishing loom having a shuttle adapted to contain a coreless package of illing and means periodically to enter past the outer surface of said shuttle and 'to feel for and to Contact with said coreless package of lling therein and means rendered operative by engagement of said feeling means with the normally positioned tip end of said coreless package. A

22. A weft replenishing loom having a shuttle to receive a coreless package of filling and a feeler mounted exteriorly of the shuttle and adapted periodically to contact with said' lling and to move past the edge or shoulder of the said filling package when vthe same has been exhausted to a prede- -enter substantially past the shuttle wall only when the filling hasbecome substantially exhausted.

24. A weft replenishing loom having a shuttle to receive a coreless package of lling, means governed thereby to supply new filling to the loom when said coreless package of filling is exhausted to a predetermined extent, said shuttle having provisions whereby the filling package is engaged externally l and thereby the diminishing portion is'held in position until the governing means to supply new filling functions,4 and coperating actuating means positioned to enter'substantially past the shuttle wall only when the filling has become substantially exhausted.

25. A weft replenishing loom having a shuttle adapted to contain a coreless package of filling, a feeler adapted intermittently to contact with said filling and means whereby said feeler makes a relatively great inward movement past the edge or shoulder of the remaining filling in said shuttle.v

26. A weft replenishing loom having a shuttle adapted to contain a coreless package of filling, a feeler adapted intermittently to contact with said filling, means whereby said feeler makes a relatively great inward movement past the edge or shoulder of the remaining filling in said shuttle and means governed by said relatively great feeler movement to introduce new illing into the. loom.

27. A weft replenishing loom having a shuttle adapted to contain a coreless package of filling, a feeler adapted intermittently to contact with said filling, means whereby said 'feeler makes a relatively great inward movement past the edge or shoulder of the remaining lling in said shuttle and means governed by said relatively great feeler movement to introduce the replenishing shuttle into the loom.
