The leader is located in front of the tip end of the filling-supply, and after the thread enters the leader its proper deliveryis absolutely assured on either shot of the shuttle, whether the delivery is directly from the leader or from the latter to the delivery-eye of the shuttle and thence to the shed. The leader constitutes the normally closed entrance or inner end of a longitudinal thread-receiving passage provided at its outer end with means to direct the thread from the passage to the side delivery-eye of the shuttle, and usually the directing of the thread to the eye is completed upon the second pick after filling change. \Vhether this is delayed or not is of no moment in my present invention, so that the complete threading may be delayed for an indefinite number of picks without breakage of the filling or interference with its delivery, which will be' from the top rather than from the side of the shuttle. For general purposes the latter delivery is preferred, and for this reason I have provided means for automatically conducting the thread from the leader to a side delivery-eye in the shuttle.

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

Figure 1 is a front elevation of a portion of the replenishing side of a loom provided with mechanism for automatically inserting fresh filling in the shuttle when necessary, one form of replenishing mechanism being illustrated suitable for use in connection with my presentinvention. Fig. 2 isatransverse sectional detail thereof on the irregular line 2 2, Fig. 1, looking toward the left, with the replenishing mechanism in normalcondition. Fig. 3 is a detail similar to Fig. 2, but showing the relative position of some of the parts just as the fresh supplyof fillingisinsertedin the shuttle. Fig. 4 is an enlarged top or plan View of the thread-delivery end of the shuttle, showing the means thereon whereby proper delivery of the thread is positively insured and effected after a change of filling in accordance with my invention. Fig. 5 is" a longitudinal sectional detail on the line 5 5, Fig. 4, viewed in the direction of arrow 55. Figs. 6 and 7 are transverse sectional views on the line 6 6, Fig. 4, looking toward the right, the threadleader being shown closed in Fig. 6 and open in Fig. 7, ready in the latter case to receive the thread of filling. Fig. 8 is a side elevation of the means (detached from the shuttle) for effecting the proper delivery of the thread, and Fig. 9 is a perspective view of the threaddelivery end of the shuttle.

Referring generally to Figs. 1 to 3, the loomframe A, lay A slotted at 10 below one of the shuttle-boxes, as B, the hunter 0 on the lay, and the filling-feeder F are of well-known construction, the filling-feeder consisting of two disks 0. a which support between them the filling-carriers or supplies of filling b, said disks rotating in unison on a stud a, rigidly secured to a stand A mounted on the breastbeam A at the side of the loom adjacent the sh uttle-box B The thread or filling ends are led from the tip ends of the filling-carriers over a disk I) (see dotted lines, Fig. 1) to a holding-stud b the latter and the disk rotating intermittingly with the feeder to present the filling-supplies b one by one into position to be transferred to the shuttle, all substantially as shown in United States Patent No. 664,790, dated December 25, 1900, the rotation of the feeder being effected herein substantially as provided for in said patent. As therein shown the stand A herein is provided with a horizontal stud f, on which is loosely mounted the hub of the transferrerf', extended between the disks a a of the feeder to engage the head of the filling-carrier to be transferred, while the tip of the latter is engaged by the notched downturned end 22 of a lateral arm 21, rigidly secured to the transferrer. \Vhen a change occurs in the condition of the filling in the shuttle, such as its exhaustion to a predetermined extent or its breakage, the replenishing mechanism is automatically actuated to furnish the shuttle with a fresh supply of filling, the actuation of said mechanism being effected in wellknown manner by the turning of a controlling rock-shaft d in the direction of arrow 65, Fig. 2, said rock-shaft having fast thereon an arm d held in the position shown in Fig. 2 by a strong spring d A shuttle-feeler 11 fulcrumed on the frame at y, is provided with a toe 1 against which the arm 0V is held by the spring, the shuttle-feeler having a rigidlyconnected branch 1 A headed rocker-stud m is mounted on the depending end f of the transferrer, said stud being normally turned in the direction of arrow 12 by a spring on Fig. 1, and an arm m, secured to the stud, has a lateral lug m flagainst which the branch g rests, and a notched dog "m is adjustably secured to the arm on, the dog being moved into the path of the hunter 0 when achange of filling is to be effected, all as provided for in the patent referred to.

In Figs. 1 and 2 the replenishing mechanism is shown in normal position, while in Fig. 3 the parts are shown in the position assumed at the instant a filling-supply has been transferred from the feeder F and inserted in the shuttle S, the old or spent filling-carrier having been ejected from the bottom of the shuttle and through the slot 10 in the bottom of the shuttle-box B So far the mechanism described is old and not of my invention ;-but a general idea of the operation thereof is necessary to a correct understanding of my invention.

I have attached to the downturned end 22 of the lateral arm 21 a cam-like actuator 75, which at the time a fresh supply of filling is inserted in the shuttle, as shown in Fig. 3, operates to efiect at such time a positive cooperation between the fresh thread end of filling and the thread-delivering means on shuttle being provided with any suitable form of holding device to grasp the head of the filling-carrier and maintain it in position in the opening 5- with its tip end adjacent the delivery end of the shuttle. The shuttle wood is cut out at such end to receive the major portion of the thread-delivering means, which is preferably made as a casting comprising an elongated bodySO, having a depending stud 81 to enter a hole 3 Fig. 5, in the shuttle, the.

body having a longitudinal thread-receiving passage 82 therein formed by the upward extensions or Walls 83 84 of the body, the inner faces of said walls being flared to present a wide open top for the passage. At its inner or entrance end the passage is contracted by inward bulges 83 8% of the walls, and said.

bulges are vertically and oppositely slotted, as at 85 86, respectively, while the exterior of the wall 84: has two lateral ears 87 on opposite sides of the slot 86. the bottom of the slots and crossing the passage 82 at its contracted entrance 82 I have a piece of felt, to exert a sufficient drag or tension upon the filling-thread as it draws off.

through the passage, a pin 89, Figs. 6 and 7, holding the pad in place. The ears 87 have pivotally mounted between them on a pin 90 a finger-like closer or cover 91 for the en trance end of the thread-receiving passage, this entrance, with its cover, constituting a normally closed leader, as I have termed it, located in front of the tip or delivery end of and substantially alined with the fillingsupply and through which the filling-thread is led or directed as it is drawn off to be delivered. Thiscoverorclosure9lswingstransversely to the passage 82 in the slots 85 86, and when in normal position its free end rests on the top of the pin 89, (see Fig. 6,) completely closing the leader, so that if the filling-thread is therein it cannot by any possibility fiy or whip out, the leader normally being a closed eye, the cover forming a threadretainer. In its open position, which is assumed for the admission of the thread or filling end, the cover or retainer is swung up into the slot 86, its free end then being hooded or protected by the bulge 84, so that no obstacle will be presented to entry of the thread end, the top of the slot acting as a stop for the retainer. (See Fig. 7.) The retainer has a cam-slot 92 therein eccentric to the pivot 90 and which is entered by a spring-linger 93 on a plate 94 of spring metal, herein shown as snapped into a socket s formedin theinner face of the shuttle-wall.

place in the socket and in dotted lines swung (See Fig. 8.) In

Referring to Fig. 5, this plate is shown in full lines in up on a retaining-rivet 95, passed through the shuttle-wall, and it will be seen that this plate is quite deeply notched longitudinally, as at 96, to permit the upper portion 97 of the plate to be bent inward to present a cam-surface 98, the finger 93 forming an extension of the cam portion, the positions of the cam portion, corresponding to closed and open positions of the retainer 91, being shown respectively in Figs. 6 and 7. Normally the resiliency of the plate 94 maintains the cam-surface projecting inward toward the longitudinal center of the shuttle, as in Fig. 6, so that the finger 93 holds the retainer with considerable force against thepin 89, eifectually and positively closing the leader, the finger moving in a recessed part 840 of the wall 84, Figs, 6 to 9. If the cam-surface 98 is pressed outward, however, toward the shuttle-wall, as in Fig. 7, the finger 93 by its outward movement travels in the cam-slot 92 of the retainer 91, and thereby quickly swings the latter-up and outward into the position shown in Fig. 7, opening the leader and pertransferrer to normal position after transferefiect disengagement of the cam 75 and the cam-surface 98 than the latter springs inward to normal position, closing the leader with the fresh filling-thread therein before the shuttle is moved from the shuttle-box by the picking mechanism, the concavity of the retainer 91 on its lower edge assisting in depressing the thread with it should the latter be raised somewhat between the filling-supply and the disk 19 The closing action of the retainer is thus an additional safeguard toward positively insuring the insertion -of.. the thread into the leader. At the first shot of the shuttle from the replenishing side of the 100m the thread draws freely through the leader and off of the tip or delivery end of the fillingsupply, it being remembered that the filling end is secured to the holding-stud b and the first pick of fresh filling is laid, the pull on the filling through the leader being substantiallyin direct alinement with the axis of the filling-supply.

The threading of the filling into the usual side delivery-eye 3 Fig. 5, of the shuttle will now be described, it being understood that the preferable delivery-point for the thread is from the side of the shuttle nearer the fell.

As the thread is already positively retained from the filling-feeder tends to draw the thread fully into the passage throughout the length thereof and down through a narrow, slit-like, and non-vertical clearance between the forwardly-extended and laterally-widened top 99 of the wall 83 and the forward extension 100 of the top 101 of the wall 84, the inner longitudinal edges of the tops being rounded to direct the thread into the passage between its downwardly-converging side walls. The extension 100 is slightly overlapped by the top 99, as shown in Figs. 4, 6, and 7, to pre sent the clearance 102, and usually on the first pick after replenishing the thread will be drawn through this clearance, and then on the next or return pick the thread will be drawn down around the horn 103, which is located at the front end of the wall 84, through the slot 3 in the shuttle, and thence to the side delivery-eye 8 To completely thread the shuttle is thus a progressive operation, requiring two picks at least, the term complete threading meaning the automatic direction of the filling-thread to the deliveryeye 8, and that part of the threading operation performed after the admission and retention of the thread in the leader is not broadly different from the corresponding operation in self-threading shuttles now in use. There is this great difference to be observed, however-viz., that in my present invention if the threading of the shuttle is not completed in the sense heretofore noted the delivery of the thread is in no way hindered or stopped, for once the thread is confined in the leader delivery can be made directly therefrom for an indefinite number of picks without affecting the proper operation of the loomt-hat is, the thread will draw through the leader over the end of the shuttle on picks away from the replenishing mechanism and over the retainer 91 and the top of the shuttle on the opposite pick with equal freedom. On the contrary, with threading devices now in use if the thread is not drawn down into the thread-receiving passage on the first pick and then around the horn and into the delivery-eye of the shuttle on the next pick the thread will be broken instantly on such second pick and a fresh supply of filling must be provided.

With my invention a misthread cannot occur on either pick, because the thread is brought into positive and deliverable cooperation with the leader as the fresh supply is inserted in the shuttle and nothing is permitted to depend on the thread or its position to elfeet the threading of the shuttle.

The proper and uninterrupted delivery of the thread from the shuttle under all conditions is the broad or generic object to be attical and simple manner. The block is secured in place in the shuttle in any suitable manner, as by a transverse screw 3, Fig. 5, inserted from the side of the shuttle. A transverse pin 104 across the bottom of the passage 82 near its front end supports the thread practically in alinement with the axis of the filling-carrier, so that a very direct pull is effected, an upright guide-pin 105 presenting a smooth surface for the thread as it turns the corner from the passage into the deliveryeye 3 under the heel 106 of the born, the thread traveling through the passage 82 in a path very closely approaching a straight line forming a continuation of the axis of the filling-carrier. The notch back of the heel 106 keeps the thread from jumping up out of the eye 8 after it has been directed thereinto. The leader not only provides for a delivery of the thread whether the shu ttle is completely threaded or not, but it also compels the thread to pull ofi from the supply in a direct line substantially in alinement with its axis, thus insuring the most perfect and advantageous conditions for the thread to draw 01f without being subjected to undue strain.

Sometimes the thread will be thrown forward in a loop between the filling-supply and the adjacent delivering means, when the shuttle is suddenly stopped at the end of its stroke, and heretofore some trouble has been experienced by the thread-loop catching over some part of the delivering means and breaking. Breakage of the thread from such cause cannot occur with the structure herein shown, for if a thread-loop is formed and thrown forward it will only fall upon the closed top of the leader, or if very long the loop may drop over the said closed top into the thread-pas sage beyond; but immediately upon the opposite throw of the shuttle the tension on the thread will take up such loop, drawing it back and through the leader without damage.

It is practically an impossibility for a loop to be thrown as far as the overlapped extensions 99 100, and if it should happen the beveled sides of the passage 82 would direct the loop down toward the bottom of the passage and away from the extensions.

The end of the supply of filling from which the thread draws off during weaving is termed the delivery end of the filling-supply and is so designated in some of the following claims.

The portion of thread or filling which leads from the filling-supply at the time of filling replenishing, and which is brought under the control of the means for effecting delivery of the thread from the supply of filling, is termed the filling or thread end, and also the thread end of the fresh filling-supply, and is so designated in some of the appended claims.

I have herein shown and described one practical embodiment of my invention in the best and most satisfactory form now known to me, and accordingly I have not attempted to show or describe various changes and modifications ICC which may be made as to details of construction, arrangement, and operation which may be made by those skilled in the art without departing from the broad spirit and scope of my invention. 7
