SPECIFICATION forming part of Letters Patent No. 718,576, dated January 13, 1903.

Application filed February 3, 1902. Serial No. 92,424. (No model.)

, I the supply in the shuttle, the latter is provided with a fresh supply of filling by suitable replenishing mechanism automatically actuated. Such looms require means for effecting automatically such cooperation of the zo fresh filling-thread and the 'shuttle' as will enable the thread to be properly delivered from the shuttle as the same is shot back and forth through the shed, such means being comprehensively termed automatic selfthreading means. Means for performing such function and carried by the shuttle are in very extended use and operate successfully, the operation, however, being dependent largely, if. not Wholly, upon the position 3o of the filling-thread between the filling-supply in the shuttle and the replenishiug mechl anism when the shuttle makes its first shot after replenishment, andthis shot and the following return-shot are necessary to effect the complete threading of the shuttle. If the filling-thread is not in the proper position on the first shot, the second shot cannot effect the threading of the shuttle, a misthread resulting, with filling breakage, and a new fill- 4o ing-supply must be inserted in the shuttle. This causes lossof picks, and provision must be made forarresting take-up and letting back more or less according to the number of picks lost to prevent thin places in the cloth and the product of the loom is reduced.

In another application, Serial No. 92,423, filed by me and pending concurrently herewith, l have shown novel means for positively insuring the proper delivery of the filling 5o from the shuttle after filling replenishment, the cooperation of the filling-thread and the delivery means being effected positively and surely at the instant of replenishment, the thread being so confined as to draw off substantially in axial alinement with the fillingsupply, and in such application the subsequent introduction of the filling-thread into the delivery eye of the shuttle is through the movementV ot' the latter then automatically accomplished. That invention absolutely prevents misthreads, and the delivery of the filling is not at all dependent upon the complete so-called threading of the shuttle.

My present invention also has for its object the production of means for preventing misthreads and for positively and surely effecting deliverable coperation of the fillingthread aud the shuttle at the time of replenishment; but by the construction forming the subject of this application I completely 7o thread the shuttle while it is at rest and practically simultaneously with filling-replenishment, the term threading7 being here used in its usual sense as indicating the insertion of the filling-thread in the delivery-eye of the shuttle, preferably located in its side.

The various novel features of my invention will be hereinafter described, and particularly pointed out in the following claims.

Figure l is a front elevation of a portion of a loom equipped with automatic filling-re- -plenishing mechanism of the type shown in United States Patent No. 529,940 and with one embodiment of my present invention applied thereto. Fig. 2 is a part-sectional view 85 thereof on the irregular line 2 2, Fig. 1,1ooking toward the left, the parts being shown in normal posit-ion. Fig. 3 is a similar view of a portion only of the mechanism shown in Fig. 2, but with such parts in the position assumed at the instant the fresh supply of filling has been inserted in the shuttle, the fresh filling-thread having been brought into the delivery-eye of the shuttle. Fig. 4 is a top or plan View of the replenishing end of the lay 95 with the shuttle-box thereon and the shuttle boxed, showing in plan the means for eecting the threading of the shuttle before the latter is picked. Fig. 5 is an inner side elevation of the opener for the thread-retaining lid on the shuttle and the thread-inserter, to be hereinafter described. Fig. 6 is an enlarged top or plan view of the delivery end of the shuttle with the threading means thereon. Fig. 7 is a side elevation thereof, showing the delivery-eye of the shuttle. Fig. Sis a transverse section on the line 8 8, Fig. 6, looking toward the right. Fig. 9 isa similar section on the line 9 9, Fig. 6; Fig. 10 is a similar view taken through the retaining-lid on the line 10 10, Fig. 6. Fig. 11 is a like view but showing the lid raised to permit insertion of the filling-thread into the delivery-eye. Fig. 12 is a side elevation of the threading means detached from the shuttle viewed from the delivery side. Fig. 13 is an opposite side elevation of said means; and Fig. 14 is a plan view of said means and the retaining-lid, the latter having been moved away to show more clearly the other portion of the thread-delivering means, which is mounted on the shuttle and on which the lid is movably mounted.

Referring to Figs. 1 to 3, the loom-frame A, lay A3, having the bottom of one of its shuttleboxes, as BX, slotted to permit passage therethrough of an ejected fillingcarrier, the bunter C2 on the lay, and the breast-beam A40 are and may be of usual or Well-known construction. The filling-replenishing mechanism and the means for intermittingly rotating the filling-feeder F, forming a part thereof, are and may be substantially as in United States Patent No. 664,790, dated December 25, 1900. The filling-carriers or supplies b of filling are removed one by one from the feeder by the transferrerf", mounted to rock on a stud f, secured lo the stand A7, a downturned tip-engaging device 22 being secured to the end of a lateral arm 2l, secured to the transferrer. As in said Patent No. 664,790, a rock-shaft CZ is held in normal position by a spring d3, attached at one end to a rocker-arm dx, which controls the movement of a swinging shuttle-feeler yX, having a branch y2. This branch, acting against a lug m14 on the carrier 'm13 of the notched dog m15, holds the latter out of the path of the bunter C2, as in Figs. 1 and 2, the carrier m13 being secured to a rocker-stud m12, mounted in the depending end f3 of the transferrer, a spring mx, Fig. 1, tending always to turn the rocker-stud, and thereby move the dog into the bunter-path. When the rock-shaft d is turned in the direction of arrow 15, Fig. 2, as it will be upon such a change in the condition of the filling as hereinbefore referred to, the dog m15 will be engaged by the bunter C2 on the beat-up ot' the lay and the replenishing mechanism will be operated in well-known manner, the shuttle being properly boxed. In Fig. 3 the parts are in the position assumed when the fresh filling-carrier is in the shuttle S, provided with suitable holding means, as jaws s', Fig. 4, to engage and hold the head of the filling-carrier.

Referring to Fig. 1, a disk b2, having a holding-stud b3, is secured to the outer end of the feeder F to rotate therewith, the filling end t being led from the tip of each filling-supply in the feeder, over the edge of disk b2, and then to the stud b3 to hold such end when replenishment of filling takes place. For a reason to be referred to, however, the filling end is not led in a direct line from the feeder to the disk b2; but, as shown in Fig. 1, it is slanted or so set that its point of engagement with the disk b2 will be in advance angularly of the filling-supply from which it is led, the feeder rotating in direction of arrow 16, Fig. 2. The front wall bx of the shuttle-box B is lnade somewhat shorter than usual at its outer end to expose the side delivery-eye s2 of the shuttle when the latter is properly boxed, and the front of the lay is notched, as at a3, Figs. 1 and 4, at the outer side of an upturned actuator c, fixed on the lay, for purposes to be described. The hub f2 of the transferrer is partly embraced by the segmental end y25 of a bracket 26, the shape of which is best shown in Fig. 1, extended laterally toward the outer end of the fixed stud f, which is herein made longerthan usual, the outer end of the bracket forming a segmental seat 27 for the circular hub 28 of an arm 29, said hub being mounted to rock on the studf and adjustably secured to the seat 27 by a set-screw 30, passed through a slot 31 in said seat. Aset-screw 32, passed through a slot 33 in the inner end 25 of the bracket into the hub f2, adjustably secures the bracket to said hub, and by such connection the arm 29 will rock in unison with the transferrer and about the same fulcrum f. The arm 29 is located opposite the outer end of the shuttle-box BX, as best shown in Fig. 4, and its top 34 is widened to form a firm support for a lid-opener, shown as a piece of stiff metal 35, having its rear end reduced and downturned, as at 36, for a purpose to be described, said lid-opene1` being adjustably secured on the arm 29 by a suitable bolt 37, passed through longitudinal and overlapping slots 3S 39 in the opener and top of the arm 29, respectively. The said arm, has also a depending ear 40, (see Fig. 5,) provided on its rear edge with a notch 41 to receive the lateral stop-lug 42 on a rocker 43, shown as fulcrumed at 44 on the ear 40 and having a depending laterally-extended lug 45, movable into the path of the actuator a4 when a change of filling is effected, as will be described. The rocker 43 has adjustably secured to it, as by a bolt 46, the thread-inserter, a casting of peculiar shape and best shown in Figs. 1, 2, and 5. The body 47 of the inserter is longitudinally slotted at 48 to receive the bolt 46, and the rear end of the body is bent to form a gooseneck 49, the downturned bill 50 of the gooseneck being also bent outwardly, asin Figs. 1 and 4. The downturned hook thus formed by the gooseneck and its bill is'adapted to hook over the filling end between the outer end of the filling-feeder F and the disk b2 as the corresponding filling-carrier is transferred from the feeder to the shuttle, and after the transferrerf has been depressed by cooperation of the bunter C2 and dog m15 the IOO IIO

actuator d4 Will by the completion of the forward movement of the lay engage the offset lug 45 and rock the gooseneck about the center 44 into the position shown in Fig. 3, a spring 51, attached to the lid-opener and thread-inserter, normally maintaining the gooseneck in the position shown in Figs. 2 and 5, with the stop-lug 42 in the notch 41. It will be remembered, however, that the movement of the gooseneck will at first be in unison with the movement of the transferrer f and about a common fulcrum f during the exceedingly short portion of time which elapses between the engagement of the bunter C2 and the notcheddog and the subsequent engagement of the actuator '21.4 with the lug 45, so that the complete movement of the gooseneck from normal position to the position shown in Fig. 3 is compound. -The first part of its movement brings the gooseneck into engagement with the filling end t, and the Iinal part of such movement positively inserts the filling end in the thread-passage and delivery-eye of the shuttle, such passage and eye having been previously opened by or through the action of the downturned end 36 of the lid-opener 3 5, as will be described.

In Fig. 4 the lid-opener is shown as having opened the lid of the threading means onV the shuttle,andvthe filling end or thread t is shown as having been inserted by the gooseneck into the thread-passage and delivery-eye,the notch o3 in the front of the lay permitting the final movement of the thread-inserter. As soon as the pressure of' the actuator d4 upon the lug 45 is removed, as by the backward movement of the lay, the spring 51 instantly operates to swing the thread-inserter upward on its fulcrum 44 into the relative position shown in Fig. 5, and thereafter as the transferrer f resumes its normal position the lid-opener and thread-inserter will be moved bodily therewith back into their normal positions (shown in Fig. 2) and entirely out of the way of the filling-thread as the threaded shuttle is shot from the shuttle-box BX. In order that the thread-inserter may engage the lilling-thread, as has been described, it is necessary to set the filling end ahead of the disk b2, as shown in Fig. 1 and hereinbefore referred to, as otherwise the thread-inserter could not catch the thread to insert it upon movement of the inserter into operative position.

The construction ofthe threading or threaddelivering means ou the shuttle will now be described, having reference more particularly v to Figs. 6 to 14, inclusive.

The body of the shuttle S is provided with an upright edge S5 at its rear,v while the upright and beveled front wall has preferably secured to it a friction-pad S6, of felt or other suitable tension-producing material, the friction-pad and upright edge S5 forming,with the shelf s4,a reentrant opening in the side of the shuttle, constituting a species of vestibule, as it were, for the delivery-eye s2. The threading-block is preferably made as' a casting and comprises a base 60, having a depending threadedstud 61 to pass through a hole in the bottom of the shuttle and to receive a retaining-nut 62, which enters the countersunk end of the hole s7in the shuttle,as shown in Fig. 10. An additional securing device comprises a transverse bolt 63,passed through the shuttle from side to side and through a hole 64 in the base 60.

Referring to Fig. 14, the base has a diagonal thread passage or groove 65, which, as shown in Fig. 6, has its inner end substantially opposite and in front of the tip of the filling-carrier, in axial alinement therewith, while its outer end s2` constitutes the lower part of the delivery-eye and opens out upon the shelfs4. At its front end the base has an upturned transverse ear 66 and at its rear end a second ear 67, said ears supporting a pin 68, on which is fulcrumed the lid to be described. The ear 66 is upwardly and forwardly extended, as at 69, presenting astop-shoulder 70, while the ear 67 is upwardly extended and convexed, as at 71, to form one side of a iiaring mouth for the passage 65, the opposite side of the mouth or entrance being formed by the inner end of the outwardly beveled or flared front wall 72 of thethread-passage, said front wall having a recess or pocket 73 therein. The front upright edge of the said wall is rearwardly beveled, as at 74, and inside such beveled edge the wall has an upright recess 75, the lower end of which is just above and immediately in front of the eye s2, Fig. 14. A movable lid member 76 has a longitudinal rib 77 on its top along its rear edge and two depending ears 78 79 on its under side, (see Fig. 13,) the fulcrum-pin 68 passing through the ears to thereby pivotally support the member 76, the ears thereof entering between the upturned ears 66 67 on the base. The edge of the member -76 is transversely convexed, and the ear 78 is extended forward, as at 80, to constitute the lid proper for the eye s2, said lid being adapted to enter the groove under normal conditions (see Fig. 10) and contact with the bottom thereof to thus positively close the open top or entrance to the said eye, a spring 312, Figs. 10 and 13, acting upon the lid member 76 back of its fulcrum to retain it in the position IOO IIO

lid S0 the member 76 is cut away to present a shoulder S3, which butts against the upright shoulder when the lid is in normal position to thereby close the space between the lid and the convex front face of the ,extension 69 and prevent the thread from being caught. At its rear end the member 76 is shaped to form a downturned guard S4, which normally spans the inner end of the passage 65 and enters the recess 73 in its front wall, the rear edge of the guard being concaved, as at 85.

Referring to Fig. 6, it will be seen that when the parts are in normal condition the passage 65 is covered by the lid member 76 from the rear edge of the guard S4 to the delivery-eye s2, the latter being shut by the lid 80, as described, and if the thread has been inserted in the eye while open it cannot thereafter escape and is positively retained therein. The convex upper and front surfaces of the guard 84 and member 76 act to direct the thread thereover and down into the thread-passage back of the eye, and when the thread is drawn beneath the point of the guard the latter prevents it from throwing or twisting out of the entrance end of the passage. A transverse slot S6 in the rear end of the base GO receives a piece S7 of felt or other suitable friction material to act upon the thread asit is drawn through the passage to the delivery-eye.

Referring to Figs. 7 and l2, the front wall of the passage 65 has a depending prong SS, which enters the shuttlewood and bears against the upright rear Wall $5 of the vestibule to present a smooth surface for the thread to pass over during its delivery when the shuttle is thrown from left to right. So long as the loom continues to run under proper operative conditions the parts mou nted on the shuttle will remain in the relative p0- sitions shown in Figs. 6 to l0, but when filling replenishing is necessary a rapid change is effected. Vhen the transferrerf' is moved to insert a fresh supply of llingin the shuttle, the lid-opener 35 is moved until its tip 36 engages the top of the member 76 against the rib 77 behind the fulcrum, and as the llingsupply enters the shuttle the lid-openei1 will tilt the member 76into the position shown in Fig. ll against the action of the spring S12 to thereby open the delivery-eye s2 of the shuttle. At the same time the transferrer movement has brought the thread-inserter into operative position, so that the gooseneck 49 hooks over the fresh filling-thread just outside the shuttle and near the delivery-eye. Then as the lay completes its forward movement the actuator a4 hits the lug 45 and rocks the thread-inserter on the center 44 into the position shown in Fig. 3, thereby drawing the thread down over the convex front of the member 76 and the front edge of the lid 8O between the parts 69 and 74 and into the then open eye. As the lay swings back thereafter the lid closes down onto the open top of the eye, absolutely preventing withdrawal of the thread, and the thread is ready for instant delivery before the shuttle has started from the replenishing shuttle-boX-. c., before it has been picked. When the thread is inserted in the eye, as described, it may or may not at the same time shed over the guard 84 and into the thread-passage 65; butif it does not do so immediately the pull of the thread will soon cause it to slide down between the convexed front edge of the member 76 and the flared face of the wall 72 into the passage and under the guard, the point of which enters but does not touch the bottom of the recess 73, as shown in Fig. 9. So far as effective operation isf concerned the shuttle is completely threaded for delivery of the filling before the shuttle leaves the shuttle-box and at the instant of filling replenishing. The bottom of the passage 65, leading to the delivery-eye, is practically in a horizontal plane intersecting the center of the fillingcarrier, so that the thread is drawn off the latter in a line very closely coinciding with the longitudinal axis of the filling-carrier, so that there is no undue strain on the thread due to oblique pull on the iirst pick after replenishment. After the thread is inserted in the passage 65 and the eye and confined therein its path is easy and free.

The end of the supply of filling from which the thread draws off during Weaving is termed the delivery end of the filling-supply andis so designatedin some of the following claims.

My invention is not restricted to the precise construction and arrangement shown and described, as the same may be modilied or varied in different particulars without departing from the spirit and scope of my invention.
