SPECIFICATION forming part of Letters Patent No. 718,587, dated January 13, 1903.

Application filed December 11, 1901. Serial No. 85,486. (No model.)

To all whmn it may concern:

Beit known that I, EDWARD S. STIMPSON, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvementin Automatic Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to looms provided with automatic filling-replenishing mechanism of the type wherein .the running shuttle is provided as occasion demands with a fresh supply of filling, and heretofore the shuttle has been provided with an automatically-selfthreading device.

In my present invention I have devised means independent of the shuttle for positively threading the same when a fresh fillingsupply is inserted in the shuttle, and the-latter instead of being provided with a threading device is made with a thread-delivery eye having a continuous rim. In other words, such delivery-eye is merely a hole made in the side wall of the shuttle, and the filling is threaded through this eye by novel threading means, which form the main part of my invention.

Figure 1 is a right-hand side elevation of a portion of a loom provided with automatic fillingreplenishing mechanism, the feeder thereof and the lay being shown in section and with one embodiment of my invention being applied thereto. Fig. 2 is a detail of a portion of the apparatus shown in Fig. 1, but with the shuttle-threading means in position to thread the shuttle, afresh supply of filling having been just transferred to the latter. Fig. 3 is a front elevation of the apparatus shown in Fig. 1 with the parts in the same relative position. Fig. a is a plan View, partly broken out, of the end of the shuttle provided with the thread delivery eye. Fig. 5 is a front elevation thereof. Fig. 6 is a perspective detail of a part of the threading means detached. Fig. 7 is an enlarged side elevation of the thread-catcher as it appears when it enters the shuttle preparatory to threading sition.

it, and Fig. 8 is a similar view showing how the thread is caught and held as the catcher is withdrawn from the shuttle.

Referringto Figs. 1 and 3, the loom-frame A, the lay A slotted at 10 below one of the shuttle-boxes, the hunter C on the lay, and the fillingfeeder F are of well-known construction, the two disks a a which support between them the filling-carriers I), being connected to rotatein unison on a stud a, rigidly secured to a stand A mounted on the breastbeam A, the filling ends being led over an outer disk I) (see dotted lines, Fig. 3) and thence to a holding-stud said stud and the disk b rotating intermittingly to present the filling-carriers one by one in transferring po- The feeder and the means for effecting its rotation are substantially as shown in United States Patent No. 664,790, dated December 25, 1900, and need not be further described herein, as in said patent the stand A supports a horizontal stud f, on which is loosely mounted the hub f of the transferrer f, extended between the disks of the feeder, engaging the head of the filling-carrier,-while the tip of the latter is engaged by the notched and downturned end 22 of a lateral arm 21,,

rigidly secured to the transferrer f, and a yielding tip-supportf is mounted on an arm f secured to the stud f, as in said patent. The transfer of a filling-carrier to the shuttle is effected when a change occurs in the condition of the filling in the shuttle-such, for instance, as its exhaustion to a desired extent or its breakage-such a condition effecting in well-known manner the turning of a rock-shaft d in the direction of the arrow '65, the rock-shaft having fast upon it an slot y", entered by a lateral lug on, secured to an arm m, rigidly mounted on a stud 'n pivoted in the lower bifurcated end of a depending arm f secured to or forming a part of the transferrer-hub f A notched dog an is secured to the arm m and when the rockshaft (1 is turned in the direction of the arrow 65, Fig. 1, the shuttle-feeler is through arm d swung rearwardly into operative position, and the branch acts to swing the arm 777. and move the dog m into the path of the hunter C the movement of the dog being therebyeffected in a positive manner. When the hunter engages the dog, the trausferrer is depressed in well-known manner to transfer the lowermost filling-carrier in the feeder to the shuttle the lay reaches its forward position, as shown in Fig. 2.

Referring now to Figs. 4 and 5, the shuttle S, having a longitudinal opening 8X for the filling-carrier, which is held therein by suitable holding means, (not shown,) is provided with a rather large aperture 8 in its side wall near one end, forming the thread-delivery eye, and a transverse wall 3 separates the opening s from a smaller chamber 3 with which the eye 8 communicates. A central longitudinal depression or groove 5 is made in the shuttle-body in front of the chamber 8 and a notch 6 in alinement therewith is made in the top of the wall 8. \Vhen a filling-carrier is transferred to the shuttle, its filling end, which it will be remembered is passed around the disk b and fastened to the stud D will enter the notch 6 and groove 5, crossing the chamber 5 and, as will now be described, a thread positioner engages such part of the thread and pushes it down into the chamber into position to be engaged by a thread-catcher which enters the shuttle through the eye 8. A lateral arm h has at its inner end a concave seat 72. Fig. 6, to fit the hub f of the transferrer, to which said arm is secured by screws 8, the outer end of the arm having a socketed enlargement It, provided with a downturned apertu red ear 7?? to loosely embrace the stud f, and the threadpositioner is secured to the head and is extended rearwardly. The thread-positioner is shown as a straight blade-like member k, having its rearend bifurcated and bent to present two downturned fingers 7t 7t, slightly separated and notched or concaved at their tips, as atk", Fig. (5, the normal position of the threadpositioner being shown in Fig. 1, its fingers being so located that when a transfer is effeeted the movement of the transferrer rocks the blade-like arm k and causes the fingers 7a to enter the chamber 5 in the shuttle, the notches engaging the thread and pressing it down into the chamber. This position of the thread-positioner is shown in Fig. 2, the filling-thread being omitted to avoid confusing the drawing, the deep notch 6 in the wall 3' of the shuttle receiving the thread as it is pushed down into the chamber 8 An L-shaped leg 13 is loosely mounted on the studfadjacent the head 71, the socket portion 71. of the latter receiving the hub 17* of said leg, the latter being held in place by a bentstop-finger f secured to the stud f by a suitable set-screw 10. The foot 19 of the leg 2) is longitudinally slotted at 12, Figs. 1 and 2, to receive a clamping-bolt 14:, which passes through a thin flat extension 19 and adjustably connects it in a rigid manner with the leg, the extension being reduced in thickness toward its rear end and having its extremity turned up and forward to form a hook 19 which constitutes one member of the thread-catcher. A cooperating member fiis fulcrumed at p on the side of the memberp and has its rear end slightly upturned, as at 19, (see Figs. 7and 8,) the opposite end of the member 1) being drawn down and tempered to constitute a spring 137, which at its extremity is bent laterally and inserted in a slot 16 in the extension 19 the spring normally acting to lift the tip of the member 19 so that it lies against the side face of the hook 19 as in Fig. 1. The legp is so located on the studf that when the said leg is swung into operative position the members 19 19 will enter the eye s of the shuttle when the lay beats up, the front wall b of the shuttle-box B having an opening 79 therein to permit such movement.

Referring to Fig. 3, it will be seen that the stud at) is bent down at n and then laterally at m the latter portion being extended far enough to pass beneath the lower edge of the extension 19 and as the stud n turns with the arm m it will be manifest that when the latter is moved to bring the dog m into the path of the hunter C the part 11 of the stud will act upon the extension 19 swinging it and the legp about the studfinto the position shown in Fig. 2, the bent stop-finger f limiting such movement by engaging the leg 1). Of course this positioning of the thread-catcher is effected before the lay heats up, so that as it comes forward, the shuttle being in the box B the extremities of the membersp and p will pass through the openings Z2 and the eye 3 of the shuttle into the chamber 5 of the shuttle. Ashelf b on the shuttle-box wall b at the bottom of the opening 5 acts upon the lower edge of the member 19 in front of its fulcrum p tipping said member against the action of its spring end 19 so that its tip 19 will be depressed into the position shown in Figs. 2 and 7 and leaving the hookp open. When filling transfer is effected, immediately thereafter the positioner k acts with its fingers 76 upon the thread, pushing thelatter down under the beak of the hook p ,the fingers at such time straddling said hook and the tip of its cooperating member 19 and as the lay begins to move back the thread is pulled completely into the hook, while the transferrer and thread-positioner return to normal position. As the lay recedes the controlling-shelf I9 releases the member 19 so that its spring 19 immediately rocks it to lift its tip 19 which is beneath the filling-thread i, Fig. 8, and as the memberp assumes its normal position with its tip contiguous to the top of the hook p the thread will be nipped between the two adjacent faces, and the bight of thread so held is pulled through the deliveryeye 3 of the shuttle. One end of the bight leads through the eye into the chamber and thence to the holding-stud b and the other end leads through the notch 6 to the filling-carrier in the shuttle, and when the latter is thrown across the lay the thread is broken between the stud b and the thread-catcher, the thread at the other side of the latter drawing off through the notch 6 and eye 3 from the filling-carrier in the shuttle. After one or more picks the thread between the edge of the cloth and the thread-catcher is severed in i that the shuttle-threading means is entirely independent of the shuttle and that the shuttle is positively threaded by such means. So, too, the shuttle has a thread-delivery eye with a continuous rim, as distinguished from an eye having a thread-directing slot leading thereto, the structure of the shuttle being greatly simplified and its weight decreased. These features are broadly new so far as I am aware, and accordingly my invention is not restricted to the precise construction and arrangement herein shown and described, for the same may be rearranged or modified in various particulars without departing from the spirit and scope of my invention.

When the spring S is free to act, it operates through the rock-shaft d and arm 01 to restore the shuttle-feeler y and the dog in to normal position, the turning of the arm 'm by or through the action of the cam-slot y permitting the leg 1) and its attached threadcatching means to return to the position shown in Fig. 1.

The enlarged upper end of the cam-slot per" mits the movement of the dog m and its supporting-arm m when the former is engaged and moved by the hunter 0 as the lay heats up.
