SPECIFICATION forming part of Letters Patent No. 600,488, dated March 8, 1898.

Application iiled November 27. 1896. Serial No. 613,579. (No model.)

To a/ZZ whom t may concern:

Be it known that we, RANDOLPH CRoMPToN and HORACE WYMAN, ot Worcester, county of VOrCeSLer, State of Massachusetts, have invented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification,

like letters and iigures on the drawings representing like parts.

This invention has for its object the production of a loom in which, when the filling is broken or exhausted from the shuttle, that shuttle will be ejected and a new or spare shuttle supplied with filling will be automatically substituted for it.

In our improved loom one end of the lay carries and has movably mounted upon it a sliding shuttle-box, which we shall designate as the running7 shuttle-box, and coperating with the said running shuttle-box we employ an auxiliary shuttle-presenter, it normally standing still and containing a spare shuttle provided with filling, the end of the filling on the shuttle in the auxiliary shuttlepresenter being connected with a suitable iilling-holder.

Then the filling in the shuttle, which is thrown pick after pick from the running shuttle, is broken or exhausted, the auxiliary shuttle-presenter, which is unattached to the running shuttle-box and which, while the shuttle in the running shuttle-box is being thrown pick by pick, is locked or held in its inoperative position, is released to come into position under the running shuttle-box, and thereafter the auxiliary shuttle-presenter is moved to put it into its temporary operative position, the running shuttle-box being displaced, so that the shuttle in the auxiliary shuttle-presenter may be thrown therefrom across the lay. Prior, however, to throwing the shuttle from the auxiliary shuttle-pre- Senter across the lay the shuttle having the broken filling is returned into the running shuttle-box, so that when the latter is put into its inoperative position and the auxiliary shuttle-presenter into its operative position the exhausted shuttle then in the running shuttle-box in inoperative position may be extracted or taken from said running shuttle-box automatically.

The running shuttle-box, it having a binder at one side, is slotted at its rear side for the entrance of a picker which is made movable in usual manner on a picker-guide rod, and the auxiliary shuttle-presenter, it also having a binder, has at its rear side a slot for the entrance of the picker, so that whenthe auxiliary shuttle-presenter is put into its operative position opposite the level of the race of the lay the picker referred to may enter said presenter and throw the shuttle across the lay.

The picker has operatively connected with it an ejector which, as the picker is retracted, engages the spent shuttle in the running shuttle-box then in its inoperative or abnormal position and withdraws the said spent shuttle from said shuttle-box, so that as soon as the spare shuttle in the auxiliary shuttlepresenter has been thrown across the lay through the shed the running shuttle-box may descend into its operative position at the level of the race ot' the lay to receive said spare shuttle on its return flight, it being thereafter thrown from said running shuttlebox until the thread in it is exhausted, when the same operation referred to again takes place.

The auxiliary shuttle-presenter detached from the running shuttle-box is herein shown as provided with a shuttle-box rod, which, through a suitable lever actuated, it may be, by any usual shuttle-box-lever-actuating devices, may be raised and lowered at the proper and desired times, and, as herein shown, the movements of the pattern-chain controlling the shuttle-box mechanism are determined through the movement ot' the filling-fork. At that pick at which the spare shuttle is thrown across the lay the movement of the take-up may be stopped. In. other words, it will be seen herein that the so-called running shuttle-box is movably mounted on and travels with the lay in its to-and-fro movements and that said shuttle-box normally stands in such position on said lay that the shuttle carried by it may be thrown therefrom across the lay so long as the lling is unbroken, but that said box is free to be put into its inoperative or abnormal position when the filling breaks, it being put into such inoperative position, however, only after the breaking of the iilling, detected in usual manner, as by a filling-fork, and the shuttle with the broken filling has been returned into the said running box. The running shuttle-box, having received the spent shuttle, is put into its inoperative position, as stated, and the auxiliary shuttle-presenter normally unattached to and disconnected f rom the running box and whose sole function is simply to supply the raceway of the loom with the spare or fresh shuttle for the one in which the iilling has just been exhausted is released from its normal inoperative position and is put temporarily into operative position at the race of the lay, it having combined with it, for the purpose of so moving it from its inoperative into its operative position, suitable actuating mechanism, it remaining in its operative position at the level of the race of the lay only long enough to enable the spare shuttle contained in the auxiliary shuttle-presenter to be thrown across the loom, said shuttle on its return stroke entering the running shuttle-box, it having had the spent shuttle extracted from it and having returned into its operative position at the level of the race of the lay.

We believe ourselves to be the first in a loom to'employ with a lay having a running shuttle-box, which travels with and partakes of the motions 4of the lay, an auxiliary unattached Shuttle-presenter which during the regular operations of the loom is heldin a stationary or inoperative position, so that it may be easily provided with a spare shuttle, said unattached shuttle-presenter being put into its operative position in place of the running shuttle-box on the failure of the filling in the shuttle contained in the running shuttle-box or, in other words, we have,'as,we may say, divided a multicelled shuttle-box into two parts, leaving each part capable of being put into operative position opposite the level of the race of the lay, so that a shuttle in each of said boxes may be thrown therefrom across said lay, and we have provided means to hold one of these boxes, which for the sake of clearness in the description of operation we have called the unattached shuttle-presenter, in its inoperative position, except at a pick following the exhaustion or breaking of a thread in the running shuttle-box, the said unattached shuttle-presenter being then put into operative position with relation to the lay, so that the picker will take from it its spare shuttle having a fresh supplyof filling, the said unattached shuttle-presenter, deprived of its spare shuttle, being immediately put again into its inoperative position, where it may be again supplied with a spare shuttle without stopping the loom.

Figure l in front elevation, broken out centrally, however, represents a sufficient portion of a well-known loom with our improvements added to enable our invention to be understood. Fig. 2 is a detail to be referred to. Fig. 3 is a left-hand end view of the loom shown in Fig. 1. Fig. 3 is a detail of the shuttle-box-lever-actuating crank-shaft. Fig. 3b shows the gear on said shaft. Fig. 4 is au enlarged rear side elevation of one en d of the lay and the running shuttle-box and the auxiliary shuttle-presenter, the running shuttlebox being elevated preparatory to ejecting the spent shuttle from it. Fig. 5 is a top view of Fig. 4. Fig. 6 shows the rear side of the shuttle. Figs. 7 to l2, inclusive, show dierent sectional views of the lay and of the running shuttle-box and auxiliary presenter in positions which they assume in one round 0f operations.

A is the loom-frame; A', the breast-beam; A2, the lay; A3, the lay-connecting rods; A4, the crank-shaft; A5, the rock-shaft, on which are mounted the lower ends of the lay-sword; and A6 is the lower or cam shaft, which derives its :motion from a toothed gear thereon, which is actuated by a toothed gear on the crank-shaft, said gears being shown simply by dotted circles, the crank-shaft having two rotations to one of the cam-shaft.

The cam-shaft has fast on it a cam a, which during each rotation acts upon the long arm of a hammer-lever ci', pivoted at a2, the upper end of said lever engaging the tail of the weftforl: a3, pivoted at 0,4 on the weft-fork slide a5, which when the weft fails to tilt the fork a3 and lift its tail ont of the path of movement of thezweft-hammer is caught by the said hammer, thus moving the slide in the guideway a6, secured to the top of the breast-beam.

@GX represents a rock-shaft mounted in suitable bearings of stands a7, the said rock-shaft having at one end an arm a8, having a bent end which engages the weft-fork slide, the opposite end of the rock-shaft having an arm a9, the said arm being raised whenever the weft-fork slide is moved outwardly by reason of the absence or failure of the weft.

The end of the lay has suitable guideways e, in which, as herein shown, are placed the ends of the main or running shuttle-box e', it being loosely placed in said guides and movable therein, so that the shuttle may be thrown across the lay, the direction of movement of the running shuttle-box being herein represented as vertical.

The running shuttle-box, normally, when not acted upon by the auxiliary shuttle-presenter, obeying the action of gravity, has a binder ewhich is acted upon by a spring e3,

and it has a lug e4, which, when said running shuttle-box is in its operative position at the level of the race of the lay, meets and is supported by the bar e5 carried by the lay, where it may stand in its operative position, it, as herein shown, being retained by the said lug meeting a shoulder e5, connected with the lay. The ruiming shuttle-box has also at its rear IOO IIO

side a slot es. The lay between the said guides e has a slot el, coinciding with the slot e6, the picker e8, mounted to slide on the rod e, entering the said slots e7 e6 when operating to throw the shuttle e1, which in this description we shall designate as the running shuttle, it being provided with filling.

The object of this invention is to replace automatically the running shuttle e111 by another shuttle, which we shall call an auxiliary or spare shuttle, when the filling breaks or becomes exhausted from the running shuttle.

The rock-shaft A5, constituting the f ulcrum for the lay, has loose upon it at one end outside the loom side the hollow feet of a stand c, having suitable openings or bearings c for the reception of a rod c2, provided at its upper end with an auxiliary shuttlepresenter c3, said shuttle-presenter normally holding in it an auxiliary shuttle et, said shuttle-presenter being capable of being moved to and fro about a center which is substantially the center of motion of the lay.

The lower end of the rod c2 enters a collar e5, having a pin c6, the pin receiving over it a link c1, attached to a lever es, pivoted at c, the opposite end of the lever cs, which we shall hereinafter designate as the shuttlebox lever, having jointed to it a link 010, which embraces a crank-pin 012 on a disk C14 on the shuttle-box-lever-actuating crankshaft C13, having its bearings 015 fixed to the framework. This shaft 013 has fast on it a toothed gear als, having two of its teeth removed at substantially diametrically opposite points, (see Fig. 3",) the said gear being grooved where the said teeth are omitted. rlhe groove receives the ends of two prongs of a sliding fork d10, having two teeth (Z13, which when the arms of the said fork are inserted into the said groove far enough to put the teeth Z13 into line with the remaining teeth of the gear d8, make of it a full gear, which will be engaged and rotated by the toothed sections d' cl2 of the mutilated gear CZ fast on the lower or cam shaft AU. The sliding fork has at its outer end an annular groove d, which is entered by a pin at one end of an elbow-lever d, pivoted on a stud dw, extended from a stand d, the opposite end of said lever having attached to it a link d5, attached to an arm Q11 of a rock-shaft Q15, having its bearings in a stand g1, the opposite end of said rock-shaft having a second arm Q13, to which is connected the rod g11, attached to the finger Q10, which is acted upon by the pattern surface or cam g1 of a shaft g8, said pattern surface or cam having a series of projections 7 and spaces S, so as to lift the finger Q10 and then lower it alternately in regular order when said cam is moved, it being understood that when the loom is running regularly the finger will rest on a space, but when the weft fails the cam will be moved to cause a projection to lift the linger and move the forked gear into position to put `its two teeth in line with the teeth of the gear d, so that one of the two sets of teeth d1 or cl2, whichever first arrives, will engage one of said teeth and rotate the said gear and shaft one-half a rotation and then leave it at rest momentarily,and then the second set of teeth d or cl2 will come into position and further rotate the said shaft to complete a full rotation thereof, after which the cam will be again moved and let the finger g1@ drop and move the forked gear into its inoperative position, leaving the crank-pin up. It is while the said crank is down at the completion of the first-half rotation of said shaft that the auxiliary shuttle,having a full supply of weft,is thrown from the auxiliary shuttle-presenter through the shed across the lay.

The auxiliary shu ttle-presenterhas suitable ears to receive a rod h13, on which are mounted the ears of a plate or binder k12, provided with a face or block of leather or other friction material h2 to bear on the auxiliary or spare shuttle e1, a spring b3 surrounding said rod and normally keeping the said plate or binder closed, as in Figs. 9 and 10. This auxiliary shuttle-presenter is normally held stationary in front of the lay, and it is entirely independent and detached from the running shuttlc-box and the lay and is provided with a spare shuttle, which is placed in position by hand to be taken by the said presenter and put in position at the race of the lay to be thrown onto said race. As herein shown, when the said auxiliary or spare shuttle is placed in position to be taken by the presenter the plate or binder k12, which may be located at one side of the presenter, but which is normally closed by a spring, may be turned down, said spring acting normally to keep the shuttle in place on the lay in line with the picker traveling on the guide-rod of the lay, so that said shuttle may be started from the same point at which the shuttle which was used in the running shuttle-box started in its flight across t-he lay. The plate or binder k12, which may be attached to the said shuttle-presenter, is shown as having attached to it a suitable filling end holder t11, shown as a projection about which the free end of the filling on the bobbin the auxiliary shuttle will be wound.

rlhe auxiliary shuttlepresenter has at its inner side a slot 2, which receives the picker when the latter is acting to'throw the auxiliary shuttle from said shuttle presenter. The collar c5 is secured to the lower end of the rod by means of suitable check-nuts 3, and to insure the retention of the shuttle-presenter in the proper straight line the rod c1 is provided with a collar having a forked guide 4, which embraces the stand c as the rod c2 is reciprocated.

The rod c2 has fast on it a collar b5, having at its inner side a projection b, (shown by full lines, Figs. 1 and 4, and by dotted lines, Fig. 3,) which is engaged by a suitable catch or holder lf?, shown as a notched arm ex- IOO IIO

tended from a rock-shaft bs, said catch engaging the projection h6 and holding the auxiliary shuttle-presenter in its inoperative position, Fig. 3, when the loom is running regularly. The rock-shaft bs has a second arm b9, which is bent inwardly over the loom side and crosses the arm a9 before described.

The hubs at the lower ends of the stand c embrace loosely the rock-shaft A5, and one of said hubs has an arm Z212, to which is attached a tension-spring Z913, connected to a stationary ear Z914 of the loom side.

So long as the running shuttle supplies the filling properly the catch 67 retains the auxiliary shuttle-presenter in its normal or inoperative position represented in the drawings; but as soon as the filling fails and the filling-fork slide is moved outwardly across the breast-beam the arm a9 in rising acts on the arm b9 and lifts the catch quickly, thus freeing the rod c2 and letting the spring 513 throw the auxiliary shuttle-presenter against the lay, and thereafter the auxiliary shuttlepresenter partakes of the backward-and-forward movement of the lay, while the auxiliary shuttle-presenter is actuated to perform its work, as will be described, after which it is again caught by the hook 137 and held in its normal position, as will be described.

The arm ctfhas connected to it a link g, attached to the end of a lever g', pivoted at 6 on a stand at the loom side, said lever at its opposite end having connected with it a rod g2, which is attached to a pawl-controller g3, pivoted at g4 and provided with a toe g5, a suitable spring Q60' (see Fig. 3) normally acting on the lever g to keep the lsaid toe elevated and form a rest for a pawl f6, mounted on an elbowelever B, pivoted at B2, said lever having connected with it a rod g, which in practice will be moved constantly from the' lower camshaft, as provided for in United States Patent No. 364,696, dated June 14, 1887,

the said pawl when permitted to drop into engagement with the teeth of a ratchet-wheel or cam g7, fast on said pattern-shaft g8, causing a projection thereon to act upon and raise the finger glo, pivoted at Q12. In practice the cam will be so shaped as to present alternately a high part, as a roll or projection 7 and a space 8. Vhenever the finger glo is lifted by a projection, the shaft c13 will be rotated for one hundred and eighty degrees, as will be described, to first pull down the inner end of the box-lever e8 and thereby raise the rod c2 of the auxiliary shuttle-presenter, and immediately thereafter, the shuttle having been thrown from the auxiliary presenter, the said shaft willhave given to it a movement through one hundred and eighty degrees, which will lower thesaid auxiliary shuttle-presenter, after which the pattern-surface will be moved another step by the pawl f6 to let the finger g10 drop and leave the crank up and shuttlebox-lever c8 in its normal position, with the box-rod down until again to be called into operation after the failure of the filling. When the filling is exhausted or at fault in the running shuttle, the raising of the arm a9, before described, pulls down on the rod g2 and lowers the controller g3, letting the pawlfG engage the ratchet-wheel g7 and turn the patternsurface two steps, one immediately after the other. As the finger g10 is lifted by the cam the rod Q14, connected therewith, is raised. The rod Q14 has pivoted upon it a weighted or counterbalanced catch f, which when the rod is lifted passes but without moving a toe f on a short rock-shaft f2, having an' attached secondL arm f3, to which is connected a rod f4, attached at its opposite end to a dog f5 (shown by dotted lines, Fig. 3) and pivoted at 15, said dog being weighted at f7, so that whenever the arm a9 is raised it will fall under a pin l0, extended therefrom. and keep lthe said arm elevated and the controller g3 in position to enable the pawl f6 to work twice in succession. At proper times, however, the auxiliary shuttle-presenter having effected its purpose, (to be described,) the pattern surface is moved, letting the rod 914 drop, and then the counterbalanced catch f strikes the toe ff, pulls the dog f5, and releases the arm a9, so that the catch lf may drop into operative position and be again in place to engage the auxiliary shuttle-presenter. g

The lay has attached to one of its swords a stud n, which serves as the fulcrum of the restoring device or lever'n', provided at its lower end with a link u2, jointed to a stud n3 of the stand Z914, so that the upper end of said lever is moved backward and forward with the lay, it passing forward as the lay goes forward. The upper end of this lever n has a projection n4, which as the lay is moved forward after the auxiliary shuttle-presenter has been lifted meets the projection band pushes the box-rod c2 forward toward the breast-beam, so that the projection b5 will be in position to be engaged by the catch 197 when it descends, said catch descending immediately after the rod Q14 descends", as it does at the second movement of the pattern-cam, for then the balanced dog f by its action pulls back the Weighted dog f5 to release the arm a9.

The picker-stick D, of usual construction and retracted by any usual spring or device D', enters a hole (see Fig. 5) in the picker es, and surrounding the rod e9 and embracing the picker is a slide or catch D2, having a vertical stud or finger D3, upon which is mounted an extractor D4, shown as a pivoted lever having an inturned end and acted upon by a spring i2.A (See Fig. 5.) This extractor partakes of the movement of the picker.

The shuttles used in this loom have at their rear side a notch D5, (see Fig. 6,) preferably surrounded by a metallic plate D6, the said notch being entered by the hook of the extractor when the shuttle is to be extracted from the running shuttle-box, as will be described. A

In operation let it be assumed that the running box is provided with a shuttle having IOO IIO

filling which is being properly laid into the shed and that the auxiliary shuttle-presenter is locked in its normal position by the hook bl, as represented in Fig. 3. New should the filling fail the filling-fork will not be tipped, and consequently its tail will be caught by the hammer, which will cause the filling-fork slide to be moved and effect the partial rotation of the rod aGX, lifting its arm a9 and letting the dog f5 fall under the pin 10. The raising of this arm a9 to act of the arm b9 raises the hook hl and immediately frees the auxiliary shuttle-presenter, letting the spring i113 throw it to the left from the position Figs. 3 and 7 to meet the lay, as in Fig. 8, and this same movement of the arm a9, acting throu gh the lever g and rod g2, lets the pawl f come into operation to move the pattern surface or cam and effect the lifting of the finger glo, that movement throwing into operative position the sliding fork, causing its teeth to be put in line with the continuously-rotating teeth d and (Z2 of the partial gear d, and the crank-shaft c13 will be quickly rotated by one section of said teeth for half a rotation; but just before this half-rotation takes place the running shuttle has come back again into the running shuttle-box, as represented in Fig. 9. The first half of the rotation of the crankshaft c13 quickly lifts the auxiliary shuttlepresenter from the position Fig. 9 into the position Fig. 10 and lifts in advance of it the running shuttle-box, as represented in Fig. 10, and the said running shuttlebox and shuttle-presenter remain in that position until the picker-stick in its forward movement causes the picker to act on the auxiliary shuttle marked c" and throw it from the auxiliary shuttle-presenter through the shed into the empty box at the opposite end of the lay, and as the picker is moved backwardly the ejector D4, acted upon by the spring 12, enters the slot e7 in the back of the running shuttle-box, engages the notch D5, and withdraws the e'xhausted or spent shuttle from the running shuttle-box, and, as herein shown, before the shuttle thrown from the auxiliary shuttle-presenter has an opportunity to return again the second half -rotation of the crank-shaft c13 takes place, pulling down the auxiliary shutfle-presenter from its position opposite the level of the racc of the lay and putting the running box in the position opposite the level of the race of the lay, so that it may receive on its return stroke the shuttle previouslT thrown from the auxiliary shuttle-presenter, and this done the pattern-surface is again moved, letting the finger g1@ drop, which effects the withdrawing of the sliding fork and the removal of its teeth from the teeth of the gear d8, which leaves the auxiliary shuttlepresenter down,and the said shuttle-presenter is moved forward by the restoring-lever n/ with the lay as it beats in the filling, and the hook h?, released by the descent of the rod g14 with the finger glo, as described, presents the projection h6 in position to be engaged and held by the catch 197 to keep the auxiliary shuttle-box again in its normal position. The spent shuttle, which is drawn from the end of the running shuttle-box, in this instance of this invention, drops on the floor, or it may drop into any suitable receptacle placed at the end of the lay to receive it. A spring 16, surrounding the rock-shaft 178, acts normally to depress the hook 237 and keep the arm b9 against arm a9, the rock-shaft being held in a suitable stand 17.

The devices herein shown for moving the shuttlebox lever are substantially the same as represented in United States Patent No. 260,349, dated June 27, 1882, and instead of the particular devices shown we may employ any other usual or well-known shuttle-boxlever-moving mechanism.

The disk c1'L is acted upon by a suitable brake 0', controlled by a spring o2, the brake preventing the overrunning of the shaft cl3, all as well known and common in looms.
