county of Worcester} State of Massachusetts,

haveiinvented certain new and useful Improvements 111 Automatic Filling-ReplenishngxLoomm QLWhlQlI-thfi fOllOWlDg is a full, clear, and exact specification.

Inaeertain type of automatic fillin -replemshmg'loom, .now 1n extensive an. increasinguse, when the filling on the fillingcarrier or'bobbin in the shuttle is v wo t'enoif or breaks the replenis g mechan sm' Operates automatical y to drive out of the shuttle the old or so-called s ent bobbin andreplaces it by a fresh one, t at is, ,by a

fillgF-carrier or bobbin having a full supply of mg. In addition to this the fresh or incoming filling must be directed automatically intothe delivery-eye of the shuttle, so that it will be wound off the bobbin and properly laidjin the 'shedas the shuttle makes its recipi'ocating -motions across the lay, the introduction' of the fillin to the eye of the shuttle "being technical y termed threadmgr A large percentage of failures to accomplish this introduction of the filling to the delivery-e e would not only render the 5 tioniwithout breaking 't automatic rep enishing feature valueless but cloth. f

The usual mode of threading is to draw the fillin thread down into a longitudinal passage 1n the shuttle by the motion of the latter across the lay after re lenishment, the return i'ck carrying the ing into the side de- 1Very-eye',-rcad for weaving and completely threading the s uttle. Much ingenuity has been expended in accom lishing this operahe fillin which is generally slack twisted and ten er and has =to' be manipulated with considerable care.

At the hopper or're lenishing side of the 100111 the .dlrection of t e pull of the filling when the shuttle is picked is not in line with the axis of the bobbin, but at a considerable angle thereto, and the thread is liable to catch-and break under the strain to which it is subjected by the ick. At times the "threadfails to enter t e thread-passage, or

does not remain init, at the end of the first pick, and in either case breakage is certain 'o '-;.the return pick, as will be man fest to in-the-art. These ob eetionable v Specification of Letters Patentv Application and nbmaryio, 190s. Berta! no. 415,160;

andanl'ioyin breakages are technically these faults none have been entirely succetssful, and probably no piece ofcloth is woven on an automatic loom of the type referred to which does not contain evidence of their existence, while the labor of the weaver isincreased by handling and putting extra bobbins into the filling-feeder or hopper.

In our present invention, which relates to automatic fillingreplenishing looms, our 'ob ject has been to so construct and arrange the operating parts that the mis-threads have been eliminated entirely, save in instances} v where the setting of the mechanism is wrong i or it is out of order. In accordance with our present invention, instead of depending on the movement of the shuttle across the lay to draw the new filling Y thread into the longitudinal passage in the shuttle we provide means on the shuttle which, by or through backward movement of the shuttle on the lay, assumes deliverable control of the filling thread before the shuttle is picked. H

By the term deliverable control we mean such control that the filling draws oil from the shuttle in such condition that it is' delivered properly to be laid in the shed, or in other words an effective or primary threading of the shuttle is attained. As a result when the pick occurs the filling draws on the bob-' bin substantially'in the line of the bobbin axis and is unbroken, eliminating breaking" strains and avoiding hopper misthreads'while at t e end of the first pick makes a so-called real mis-thread im ossible. That is, at the end of the first pic the filling willeither be in the thread passage and'in accurate posi:

tion to be immediatcl directed to the de livery-eye at the beginning of the second pick, thereby efiectin a complete or'fin'a! threading of the shutt maintained in deliverable condition and cannot .be broken on the return pick,

is insertedin the-boxed shuttle 12 at or Fig. 1, it being understood'that the fresh end or thread of filling-then leads from the tip of the bobbin alongthe top of the shuttle, as at 12 Fig.1, and under the edge of the plate 4 I The filling-end is then along the longitudinal axis of the bobbin, prolonged, but as the lay moves'back, the thread will be changed to lie at a considerable angle to the bobbin axis,

a portion of 'the' dotted lines to; ling having just? e; Fig. 2 is-a par-- a top plan view .as having moved backward,- but before the pick, the shuttle being. still in carrier 'unning shuttle with filling comprehends the l oonnected, and rotatable plates- 1', 2, (the vw rkhich forms endand herein the filling-carriers are. the feeder bytheusual transcontrolling means,

In automatically self-thread-iiig-shuttlesherev I tofore devised this movement of the shuttle across, thelay has been utilized to efiect cooperation between, the' filling and the threading device, so that on the return pick the-filling maybe directed to the delivery eye ofwthe shuttle.

I :Herein we utilize the backward movementof the lay to bring about an efiective threadingof the shuttle, that is, so that theQfilling will be delivered therefr'omto be'properly laid in the shed, "s accomplished while the shuttle is quiescent inthe shuttle-box prior to the'pick.

"The means which is caused to positively enage and assumedeliverable control of the filling thread by such backward movementof the lay is mounted on the shuttle butimmovably with relation thereto, as will appear, the rigid and inert structure of such means intent of the shuttle and replenishing means in a direction transverse. to the length of the being brought-into action by relative movej shuttle or in the general direction of lay movement; v

ocket is formed by the part 19 opposite the jof the 'shutt e-wood,' which part is downwardly and rearwardly inclined at 20 to lead to the open side delivery-eye 21 through which the filling draws when the shuttle is completely or finally threaded. v

making with the rear V-shaped and beyeled' entrance to the rear endof the thread passage 15, the front wall of 'the p'assagel' belng has the usual elongated alinement with the was of the filling carrier. S fThiswall at the forward end of the passage tates -gro0fve 18 which terminates at the front side d the head terminating a .125 the head 23 is down-' 'i -;-i or1ned by the back block, the latter screw 26. the beak, and a guide-pin 28 .dependsfrom the-horn, Fig. 7, terminating in an open loop' 29. The front side-of the head is down' turned at 30 to fit the front wall of the shuttle back of the part 19, forming with the side thereof a passage leading to the deliveryioeye. When afresh bobbin is inserted in the shuttle the descent of the bobbin carries the filling thread leading therefrom down be- I tween the op ositely inclined parts 14 and [5 so that will drop into the rear end of the thread passage, the thread bein' thus brought downbehind the beak 24, the general slope and direction of the wall 14 insuring this result.

part of the threading being held inplace by a 7 2b As'will be noted, the top of the head slopes iearward and is highest at itsend above the beak, Fig. 41, and the rear face 31 of the beak is quite sharply inclined fron'tward, see'Fig. 6, so that when the thread is ulled or tightened it will slide down such ace and under the tip or point of the beak, the'high part of the head at the beak insuring the positioning of the thread behind the beak as the bobbin is transferred. This ositioning'of the thread 36 12?? is shown as well as may be in Fig. 1, it

beingremembered that the thread leads outwardiunder the plate 4 and thence to the holdingdevice 5, th'e rheadLf As the'lay moves back after filling change the filling thread slides down the rear face 3] and underthe tip of the. beak, being momentarily depressed below the lip 17 and then drawing up-in front of the beak and over the lip into the groove 18, all prior to the pick and while the shuttle is quiescent in the shuttlebox.-- In-nnediatcly the thread passes under the beak and'up in front thereof the thread isv in: deliverable condition and the 4,5shuttle is effectively threaded, for as the shuttle is picked fronrthe box-10 the thread draws forward in the trough-like groove 18 and between the beak and the horn 27, as will be manifest, so that the filling is properly I laid in the shed. .The parts of the thread directing and controlling means are altogether rigid and immovable relatively to the shuttle, l obviously, I and while the beak is ready to engage and 955111116 posit ve and-deliverablecontrolof=the fres inning thread the-"carry ngo'utof .such lunctions are.

tween the shuttle path and the filling between the shuttle andthe held end of he filling having no effect whatever. on the 'return pick the filling is drawn up out of the groove 18 and over the part 19 of the shuttlebody and is drawn thence down between the rear face 20 and the part 30 of the threading block, sliding down along the born 27, around pin 28 and into the loop 29 as it is drawn through the delivery-eye 21 of the I shiittle. After the filling enters the loop 29 it is held therein by the structure of the loop, but as the shuttle and its thread directing de} vices are not claimed herein per se'furtherdetailed description is unnecessary. filling is introduced to the delivery-eye the shuttle is completely threaded, and the filling is thereafter delivered through the eye. Should the filling fail to be directed into the When the eye on the second pick after replenishment there would be no breakage, for tlie filling would still be under the controlof thejb eak and head and would be in deliverable condi tion, drawing over the top of the head as the shuttle is picked to the right. 'He nce no socalled real lids-threads can occur, due to the filling pulling off rearwardly'fronr the bobbin. f

The distance from the tip of the jfilliilgscar rier to the end-holder is qulte considerable at time of replenishment, and there is at times with some kinds of filling atendency the filling-end to curl or kink out ofits roper position behind the beak just prior to ackward movement of the lay. This can be readily overcome, however, by using when necessary a catcher or holder to engage the filling-end between the bobbin and the end-holder on the hopper, and we have shown such a catcher.

The elongated end of the stud 7 has fixedly secured to it the hub of a stationary, rearwardly extended arm 32, projecting above the lay path and having its rear end enlarged at 33 and provided with an open slot 34, Eig. 2, the extremity of the arm being shaped to present an upcurv ed finger 35 the lower edge of which leads-to the entrance of .the ,slot. At its rear edgethc slot is provided hook-like projections 36, twobeingshown below and one above the entrance to t-he slot, The filling-feeder or hopper moves forward after each transfer, to bring the next bobbin into transferring position, and. the filling-end leading from such bobbin is brought under and slidesalong the lower edge of the finger.

35 by the advance of the hopper, the filling end entering the slot 34 of the catching device. When this bobbin is transferred to the slruttle the iilling-end drops to the bottom of the slot 34-, bringing the thread as close to'the top of the shuttle as possible, the position of the slot relatively to the shuttle at the time Now as the lay moves back the filling-end Wlll be heldby the catcher, relatively near the beak on the. shuttle, see Figs. 1 and 3, but it will draw the thread down under the beak and up in front thereof into the groove 18 just as has been described, causing effective.

as in Fig. 3,'before Inasmuch as the catcher confines the filling thread quite near the beak any tendency of the filling to kink or curl out of proper position is overcome.

The general tendency of the filling-end as the lay moves back is to draw under the prothreadingof the shuttle,
