To allwhom it irbag concern.-

Be it known that I, ROBERT BURGESS, a citizen of the United.- States, and a resident of New Bedford, county of Bristol, Stateof Massachusetts, have invented an Improvement in Looms and Filling-Carriers Therefor, of

o which tnefollowing description, in connec-- tionwith the-accompanying drawings, is a specification, like characters on the drawings representingli-ke parts.

Looms provided with plenishin g mechanism comprise two classesviz., the one wherein breakage of the filling and weaving out of filling from the shuttle is detected by} the filling-fork and a fresh supply of filling is automatically inserted in the shuttle after a loss of from one-to three picks in the cloth, the other class wherein filling-replenishing is automatically effected I tent by or through the agency of afeeler to with no loss of picks upon exhaustion of the filling in the shuttle to a predetermined exfeel the filling in the shuttle. My present invention partakes of some of the characteristics of both classes, as it isemplcyed in con} nection with a 100m ofithe first above-mentioned ,class', but with means whereby when the filling'has been exhausted to a'predetermined extent, a fresh supply will be provided automatically after a loss of from one toth ree picks, but without the employment of afeeler to feel the filling in the shuttle. The absence of filling in the. shed'is discovered by the usual filling-fork in well-known, manner and filling change is efiect-ed; buta practically empty filling-carrier is ejected instead of one which is in condition to continue weaving, as

is frequently the case with the so-called The fillihg-carrierfeeler class of looms. or bobbin ieordinarily wound so that the last portion to weave oltyand which of course is the first portion wound thereupon in the spinning operation, will come off in a bunch, and considerable time and care are necessary to pick it out from the cloth, in which it forms a detect.

it will be provided with automatic filling-replenishing mechanism it is'very essential to obviate the tendency of the last portionof-the yarn on the liliing-carrier to come oft in a bunch curl. as it i;-' tcrmsid, as the weaver isse s automatic filhng-re-z manifest that in a plain loom is effected, and ,as ,a consequence many devention provides means for hotbnly-prevent ing-the'so-ealled curl from being drawn off 2 the filling-carrier and woven into the cloth, but it alsoprovides' for efieeting a'ehange'o ff filling in a non-feeler loom when the sl1uttle-. 6o

filling is exhausted jto'a predeterminedextent. f

The novel features oi my invention-willfbe hereinafter described, and particularly point: ed out in the following clailhs.

' Figure lisatop orplan view, centrally br'oke'niout, of a non-feeler loom provided with automatic filling-replenishing nechan-- ism with one embodimentjof my invention applied'Jthereto. Fig. 2 is'anenlarged plan view of a shuttle anda filling-supply therein embodying apportion ofmyI'invention,'and 3 ;is a side elevation of the filling-carrier or bobbin with the initial or preliminary winding of filling thereupon. 1 p

The general structure of' he loom shown in Fig. l is of Weil -known and usual character, andthe filling-replenishing mechanism, comprisingessentially, the rotatable feeder'jF for-fire filling-carriers; the transferrer f, by or through which the filling-barriers are transferred singly from the feederto the self-threading sh uttle'S, and the controlling reek-shaft d, having anarmtd? fastthereon, .may becut No. 529,940, dated November'27, 1894.

' The filling-fork m,-mounted'on the slide mflis engaged by the weft-hammer W if the filling is absent fromthe shed, and the slide is moved outward in well-known manner to 0 engage and swing the arm d and rock the: shaft d.

The filling-carrier or bobbin comprises a barrel Ct, having its base or head g provided with a plurality of metallic rings e to be en- 5 gaged by the holding-jaws h of the shuttle S, Figs. 1 and 2, in well-known manner, an annular space e being formed between two ad 'ja-cent-rings e.

Ordinarily the yarn the fillingcarrier atb, Figs. 2 and 3, at the .beginning of the operation, at which point a considerable number of turns arewound;

substantially as shown in United States.lat-

is spun or wound upon rco and it is some of theseturns'which are liable to come 01f in abunch or curl and be woven into the'cloth. In order to'overcome this difficulty, I cause the yarn after a few turns aroundthe barrel atb to wind downward to:

wardthe head of the filling-carriegas at c,

and I- then form what I. term' an anchor. winding by taking. so veralturns of the yarn.

about the head'in one of the annular recesses ex, the anchor-winding being shown. clearly at d, Figs. 2 and 3, after which the yarn is wound. upon .thebarrel in the ordinary way.

.will be noticed that the filling traversed from the anchobwinding to the service-winding is after.; When thefilling. is Wound oifgduring 'cause,-as will bemanifest, the holding-jaws of the shuttle grasp-the head of the fillingcarrier and prevent'the yarn from unwinding, so'that it must of necessity part. 3 Thus none of the winding at b or the curl will be drawn ofifroin the filling-carrier, and detec- .,tion of the absence of fillingby the fillingin theshuttle.

to a predeterminedextent and with a very small percentage of waste,for very little filling is involved in the winding at b c and the anchor-winding, which "I- have so designated because it serves to anchor the curl-upon the .iilling-carrier and also determines the breakin the-manner described by manipulating the ing-point of the filling. The yarn is wound ring-rail of the spinningfr'ame at the proper time Ito givelthe desired result. Instead'of permitting-the anchor-winding to effect thebreakageof the filling at the-proper time, as has been described, it will be manifest that preciselythe same results will be obtained, so far as time of filling change and reten- -tion ofthe curl upon the fillingcarrierareconcerned, by breaking the filling where itis exposed and accessible between the anchor and service windings-viz., at 3 4 'the weaver or attendant breaking the-fillingthereat as he puts each filling-carrier in the feeder of the replenishing mechanism. The

loose end of filling-thread thus left and. the

small number ofv turns of the filling imme- I diately preceding it will not make a bunch,

,.'as the turns are not wound'tightly one upon the other, as is the case in the formation of the curl.

Either automatic or manual severing of the filling can therefore be elfected Windingdown on the mule-spindle belowthe the filling when exhausted to apredetermined dentally before .the. servicerwinding' is exhausted; In the use'of cop-filling the same system can be .used by carrying the anchor- .7 79 regular traverse. This would be broken in the dofiing-or left exposed, 'so that-wh'en the cop was puton the cop-skewer for usein theloo1nhopper it could be broken-there by hand.-

6. A filling-carrier. having an annular recess in its head, and havinga filling mass having at or near its inner end auanchor-winding in said recess and a main or service winding upon the barrel of the. carrier, the filling traversed from one to theother winding being externally accessible.
