' SHUTTLE-CLEARING MEANS FOR F-ILLlNG-REPLENISHIN G Looms.

Patented Feb. 13, 1906.

To allwhom it may concern.-

Be it known that I, JONAS NORTHROP, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Shuttle-Clearing Means for Filling- Replenishing Looms, of which the following description, inconnection with the accompanying drawings, is a specification, like characro ters on the drawingsrepresenting like parts. I This invention relates to automatic looms of the type wherein the running filling is .replenished from time to time by inserting au tomatically a fresh fillin carrier into .the running shuttle and simlfi aneously ejecting therefrom the filling-carrier from which the filling is more or less exhausted. When the filling-carrier is ejected, it drops from the shuttle and pulls the old filling end through the shuttle-eye, and to clear the shuttle and prevent fouling of the fresh filling and. also to prevent the end from being carried back by the shuttle into the cloth it is necessary that the old filling end be drawn completely out of 2 5 the shuttle. This trailing filling end will always be present when the loom is provided with means to cause filling replenishment before complete exhaustion of the running filling, such so-called feeler-looms being also provided with means to part the old fillin between .the cloth and the shuttle upon filfing replenishment. Such a filling end will also be present when the running filling breaks at somedistance from the shuttle-eye, 3 5 and in either of the cases mentioned it tends to cause trouble if'it is not completely drawn out from the shuttle when the filling ,is relenished. Means to part the old filling have ,lggeen provided, as in United States Patents 0 0s. 641,792 and 677,096, and in patent to Marcoux, No. 766,151, dated July 26, 1904, means is provided to engage the old filling end between the shuttle and the ejected filling-carrier to clear the filling end from the 5 shuttle. J

My present invention has for its'object the production of novel and efiective means applicable to automatic looms of the type here: inbefore referred to to engage the old filling end between the shuttle and the ejected filling-carrier and effect in a very perfect man ner the drawing out of such filling end from the shuttle.

I have herein shown my invention applied to a loom of the Northrop type (such as shown in United States Patent No. 529,940,

for instance) and equipped with filling-exhaustion-indicating mechanism, which is substantially that shown in patent to Wood, No. 789,473, dated May 9,1905, though, aswill appear, my invention is not restricted to that particular form of filling-exhaustion-indicating mechanism. So, too, itwill be manifest that my present invention isapplicable to an automatic filling-replenishing loom not of the feeler type. i

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims. j

Figure 1 is a top plan View, centrally broken out, of a sufficient portion of anautomatic filling-replenishing loom to be under stood with one embodiment of my invention applied thereto, a portion of the replenishing mechanism being omitted. Fig. 2 is a righthand side elevation of the loom, showing the replenishing mechanism and the means for clearing the shuttle of the old filling end, the

filling-feeder, the lay, the shuttle, and the replenishing shuttle-box being shown in section. Fig. 3 is an enlarged detail, partly in plan and partly on the line 34, Fig. 2, showing the replenishing shuttle-box and the clearing means, the latter being shown in its normal quiescent condition. Fig. 4 is a similar View, but showing the clearing means as set and ready to operate to engage the old filling end. below the shuttle and above the ejected filling-carrier. Fig. 5 is an enlarged detail, in rear elevation, of the clearing means when in its normal condition.

Referring to Figs. 1 and 2, the fillingfeeder F to hold the reserve filling-carriers b, the transferrer f, mounted to rock on the fixed stud f to remove the filling-carriers one by one and transfer them to the shuttle S,"(of the automatically self-.threading type) the controlling rock-shaft d, the lay A cut away at A, Fig. 2, below the replenishing shuttlebox B slotted in its bottom at .10 to permit the discharge of a filling-carrier ejected from the shuttle at the time of filling replenishment, maybe and are of well-known construction and operation. The notcheddog m carried by the downturned extension i foot 8 is so loca f of the transferrer to coo crate with the hunter 0 onthe lay when filling replenishment is to be effected, the yoke y y fulcrumed at y and having a lug y, cooperating with the jaw-like arm (1 fast on the controlling rock-shaft d, the spring S connected with said arm, and the cam-slot y onthe yoke-arm y", cooperating with a lateral lug m connected with the dog M15, may be and are substantially as shown in United States patent to Stim son, No. 718,587, dated J anuary 13,1903. erein I have shown the yokearm y"- as forming a shuttle-feeler and provided with means (indicated at P, Fig. 2) to art the old filling end between the cloth and the shuttle when replenishment takesplace, as in Patent No. 641,792, hereinbeforere ferred to, The arm f 2, for the tip support is as shown in said Patent No. 7 18,587 the arm being rigidly secured to the stud f,

. and,'as will appear hereinafter, the means for cooperating with the old filling end is mounted on said arm. The lower end of the extension f 3 is bifurcated, as usual, and the ear 'm on the block m enters between the branches, the notched dog m being secured to the block in usual manner; but herein 1 have mounted the ear to rock on a pin 1, passed through the bifurcated end of, the extension f said rod being held rigidly in place by a set-screw 2. Said rod is bent downward at 3 and then laterally toward the right at 4, as best shown in Figs. 3 and 4, and'the part 4 having pivotally connected with it one endof a link 5. A depending bracket or support 6 is bolted rigidly at 7 to the tip-supporting arm f, (see Fig. 2,) the lower endof the bracket being enlarged to form a substantially horizontal foot 8, having an inwardlyextended lateral guide portion 9, provided with a hole 10 (see dotted lines, Figs. 3 and 4,) through which the link 5 slides loosely and by which it is s ported and guided. The te jd't at when the lay beats up the cutaway portion A will receive the foot anda diagonal outturned lateral extension 11, which forms one of the fillin endholding members, it being longitudinal y grooved or recessed at 12, Fig. 5, on its rear face and rovided at its inner end with an ear 13 beow the foot 8. A grooved non-metallic lining 14, of wood or other suitable material, is set into the recess 12 (see Fig. 3) to cooperate with the movable clearer member in holding the old filling end. The movable clearer member is shown as an elongated arm 15, conveniently made of stout wire slightly bent at its free end at 1 6 and at its opposite end.

fixedly secured in a hub 17, fulcrumed on a pin 18, set into the foot 8 and the car 13, a s ring 19, coiled around the lower portion of tile hub, being fixed at one end to the ear and at its other end to the hub, as shown in Fig. 5, the winding of the s it tends normally to ho d "sitely to arrow 24,

ring being such that the clearer member" 15 in the grooved lining 14 of the fixed mdm ber 11. (See Figs. 2, 3, and 5.) The hub 17 18 provided with a cam-hook 20, the inner face of the hook being cam-shaped, as at21,

and cooperating with the downturned rear end 22 of the link 5, the latter being slightly bent adjacent said end to clear the corner of the foot 8. While the loom is running prop erly the filling-end-clearing means remains quiescent in the position shown in Figs. 2 and 3, the downturned end 22 of the link5 resting easily in the inner end of the cam-hook 20. When lillin replenishment is called for, the rock-shaft is turned in the direction of the arrow 23, Fig. 2, lifting arm d and effecting rearward movement of the shuttle-feeler y and .operatively ositioning the parting de vice P, the cam-sibt y of the branch g at the same time cooperating with the lug 'm to swing the dog m u ward into the path of the hunter C The ay beats up, the hunter and dog engage, and as the lay completes its forward stroke the dog is pushed forward, rocking the transferrerf and its extensionf and a fresh filling-carrier is inserted in the shuttle, while the filling-carrier previously held in the shuttle is ejected through the bottom of the replenishing shuttle-box and is discharged into any suitable rece 'tacle. The old filling has in the meantime een parted between the cloth and-the shuttle by the parting device P, and the ejected fillin -carricr drops fully forward in the position shown in Fig. 4, the. arted filling end leading from the ejected lling-carrier to the shuttle. When the extension f was swung forward by the cooperation of the dog and bunter, the rod 1 was moved forward in unison therewith, drawing the link 5 forward in the direction of arrow 24, Fig. 3, and at the instant the fresh filling-carrier was inserted inthe shuttle and the old one ejected the link had beenmoved to the osition shown in Fig. 4, the end 22 of the lin acting upon and wiping over the cam-face 21 of the hook '20 to swing the clearer member 15 in a lateral path in the direction indicated by the dotted directionline 25, Fig. 3 but owing to the quickness of movement of the clearer member it had assumed the-position shown in Fig. 4 and had been set or operatively positioned before the ejected filling-carrier had crossed the lateral path ofgr'rovement of the member 15, the setting of said member acting against the force of the sprin 19 and increasing itstension. Change'of filfing having been efiected, the lay begins to move back as the transferrer f rises out of the shuttle in well-known manner and the extension f 3 moves-toward therear, of the loom, moving the link 5 oppo- Fig. 3, and the cam-face of from the shuttle while the ay is the hook 20 permits the spring 19 to quickly swing the clearer member 15 from the position shown in 4 back to that shown n Fi 3, so that said member swings behind the ol fillin end, between the shuttle and the ejected fi ling-carrier, and then carries such filling end forward to and against the fixed member 11. The return or engaging sweep of the clearer member "is indicated by the dotted direction-line 26in Fig. 4, the member 15 being lon enough to engage and carry forward the ol filling end, which is positively held between the members 11 and 15 as the latter comes to rest in the grooved lining 14:.

- bers, and'thereby being held that its loose extremity must e pulled out of the shuttle-eye and the shuttle cleared; If for any reason the clearance is not completed as the lay moves back, it will be completed as the shuttle is shot from the box B the filling endbeing held by the clearing means as the I shuttle is thrown.

The curved or bent end 16 of the clearer member 15 serves to revent accidental disengagement of the fil ing end should it slide toward the outer end of said member as the latter is swinging around on its fixed fulcrum.

So far as concerns mere breakage of filling my present invention is operative on a nonfeeler loom, as will be manifest, for Whenever the filling breaks far enough away from the .shuttle to leave a long filling end it will be cleared from the shuttle, no means beingnecessary in such case to part the filling between the cloth and the shuttle upon filling replenishment. When my invention ,is used on a feeler-lOom, however, the parting means is necessary, for it will beremembered that, in such a loom filling replenishment is called for and its operation effected by or through the feeling or filling-exhaustion indicating mechanism. In both cases the filling-replenishing mechanism is controlled as to the time of its operation by or through the controlling rock-shaft (1.

Referring to Fig. 1, the filling-exhaustionindication mechanism is shown at the lefthand side thereof, the feeler '5 having the head i to intermittingly engage the filling in the shuttle when the latter is in the left-hand shuttle-box B, the shuttle-engaging bunter i on the member i" and the transmitter i to governthe position ofthe latch (i being substantially as shown in Patent No. 789,47 3

referredto and operating as therein set forth,

ed and movable clearer mempositively, so

the latth (i being ivotally connected with the u turned arm fast on therock-shaft d. nasmuch as the function of the fillingexhaustion-indicatin mechanism is to cause the operation of t e filling-replenishing mechanism before complete exhaustion of the filling in the running shuttle, any other suitable form of exhaustion-indicating mechanism may be employed instead of that herein shown, so far as my present invention is concerned. H
