WEFT-REPLENISHING MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters 1- mtent No. 788,356, dated April 25, 1905. Application filed March 24,1902. Serial No. 99,578.

To all whom, it may concern.-

Be it known that I, HENRY I. HARRIMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in \Veft-Replenishing Mechanism for Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to the class of mechanisms which have been devised for the purpose of effecting automatically replenishment of the working weft-supply of looms when necessity arises therefor--as, for example, on exhaustion of the supply of weft or filling that is carried by the working shuttle on the lay of a loom, or on exhaustion thereof to a predetermined extent, or on loss of continuity of such weft or filling-the action of the replenishing instrumentalities being brought about or instituted through the agency of suitable forms of weft-indicator mechanism. In some types of mechanisms of the said class the replenishment is effected by discharging or removing the spent or failed working shuttle from the lay and bringing a fresh or reserve shuttle into action in lieu thereof. In others it is effected by employing filling-cases adapted for removable application to the body ofa loom-shuttle, each filling-case carrying a load of weft or filling, and by ejecting the spent or failed filling-case from the working shuttle on the lay and introducing in its place a reserve filling-case loaded with weft or filling. In others still it is effected by replacing automatically the bobbin which is contained within the working shuttle on the lay by a reserve bobbin loaded with weft or filling.

My present improvements are in part applicable to mechanisms in general of the automatic weft-replenishing class and in part are more especially applicable to mechanisms ofthe types in whichweft replenishment is effected by automatically replacing the fillingcase or bobbin in the working shuttle on the lay by a reserve filling case or bobbin.

For convenience l have in the accompanying drawings illustrated my present improvements embodied in mechanism constructed and operating to effect replenishment by making change of filling-cases, and I will thus describe the same.

In the drawings, Figure 1, Sheet 1, shows, mainly in side elevation, but partly in vertical section, a portion of a loom having the said embodiment of my improvements applied thereto. Fig. 2, Sheet 2, shows in front elevation a portion of the said loom and also represents in dotted lines a portion of a filling-case receiver located adjacent the loom. Fig. 3, Sheet 3, shows, mainlyin plan, a portion of the said loom, the magazine for filling-cases and part of the loom-frame being removed. Fig. 4, Sheet 4, shows in side elevation, and Fig. 5, same sheet, shows in plan, with part thereof broken away, a shuttle suchas is employed in the loom of Figs. 1, 2, and 3. Fig. 6, Sheet 4, is a view in vertical section on the plane indicated by the dotted line 6 6 in Fig. 4. Figs. 7 and 8, Sheet 4, are views of one of the arrangements which are applied to the shuttle-body for the purpose of holding the fillingcase in place within the chamber or cavity thereof. Fig. 9, Sheet 4, shows in front elevation, and Fig. 10, same sheet, shows in plan, one of the filling-cases which are employed in connection with the shuttle of Figs. 4 and 5. Fig. 11, Sheet 4, shows the said filling-case in vertical section on the plane indicated by the dotted line 11 11 in Fig. 9. Fig. 12, Sheet 1, is a sectional detail showing partly the positioner and its operation. Fig. 13, Sheet 1, shows the cam for operating the filling-case positioner. Fig. 14, Sheet 3, is a plan of certain details, showing partly the shuttle-box at the change end of the loom, the guides over is combined. Fig. 16, Sheet 5, is a partly-sectional view of the same looking at the change end of the loom. Fig. 17, Sheet 5, is an end elevation showing chiefly the knocking-off arrangements. Figs. 18 and 19, Sheet 6, are views corresponding. respectively,with Figs. 16 and 17, respectively, but showing the parts in the positions which they assume when there is an absence of reserve filling at the detector. Fig. 20, Sheet 7, is a perspective of the details of the picking arrangement. Fig. 21, Sheet 7, is aperspective of some of the parts which are shown in Fig. 20, but representing them as disengaged in order to effectuate the suspension of the picking. Fig. 22, Sheet 8, is a perspective of a slightly-modified picking arrangement. Fig. 23, Sheet 9, shows the same disengaged to occasion the suspension of the picking. Fig. 24, Sheet 9, is a detail View showing a modification in which the filling-case-supporting guides are attached to the front of the lay-beam.

Having reference to the drawings, a a designate the opposite end frames of a loom, and a the breast-beam thereof.

b is the lay-beam, and I) 1/ are the lay-swords, the latter being pivoted at b and the lay bein g operatively connected with the crank-shaft c by lay-pitmen I) Z), extending from the layswords I) Z) to the cranks c 0 of the crankshaft 0, as usual.

(Z is the cam-shaft of the loom.

The shuttle-box back at the change end of the lay-beam is designated 6, the shuttle-box front being designated f, and g is the corresponding picker-stick, g being the lug-strap through which motion is transmitted to the said picker-stick from the arm g of the adjacent picking rock-shaft 9 the latter being journaled, as usual, in bearings at g g, which are applied to the corresponding end frame a of the loom, and, as shown in Fig. 2, being furnished with an inwardly-extending arm g provided with a cone-shaped bowl g, that is acted upon by a picking-tappet g on the camshaft (Z.

it is the rear cross-girth.

It is not material to the invention which form or arrangement of weft-indicator devices or mechanism is employed in connection with the present improvements. Various forms and arrangements of such devices or mechanism are known, some thereof being operative to ascertain breakage or exhaustion of the weft-supply in process of being woven in and others thereof being operative when the weft-supply within the working shuttle on the lay becomes reduced in quantity to the predetermined minimum prior to complete exhaustion thereof. For convenience of illustration l have represented in the drawings (see more especially Fig. 3) an ordinary Weftfork it, which, as usual, is pivotally mounted upon a weft-fork slide 71,, fitted between guides at [L /I upon the breast beam. The weft-fork slide It is arranged, as in similar constructions, to press forward the adjacent armz' when said slide is slid forward across the breast-beam g in consequence of the engagement of the gooseneck (not shown) with the tail of the weft-work h, as in case of absence of the weft or filling from in front of the tines of the weft-fork when the lay beats up. The arm 2' is mounted upon the usual rod 21', the said rod extending across the loom just below the breast-beam and being journaled in the opposite end frames a a. The rod 2" controls the starting of the weft-replenishing instrumentalities, and, as presently will be made to appear in the further description of the illustrated embodiment of the invention, when the said rod '21 is rocked, as in consequence of an advance of the weft-fork slide it, the said instrumentalities are brought into actionand caused to effectuate the desired weft replenishment.

I have represented the parts which are more immediately concerned in the performance of the weft-replenishing operations as actuated by cams upon a change-shaft Zr, the said change-shaft being operatively combined with one of the rotating shafts of the loom (herein the cam-shaft (Z) through motion-transmitting connections including a clutch. The clutch is under the operative control of the rod i, and when the said rod is rocked in the manner which has already been explained the clutch is caused to serve in the transmission of driving power to the change-shaft, whereby the latter is rotated. The character, arrangement, &c., of the motion-transmitting connections and clutch may vary in practice as pre ferred or found necessary. In the present case, reference being had to Figs. 1, 2, and 3, the driving arrangements comprise a sprocketwheel d, fast on the cam-shaft (Z, a sprocketchain (Z passing around the said sprocketwheel (Z and also around a large sprocket-wheel (Z which is mounted loosely upon the changeshaft hand the clutch aforesaid, the latter serving to couple the said sprocket-wheel (Z to the change-shaft when required. The clutch proper is in the present instance similar to that of United States Letters Patent N 0. 652,105, granted to me June 19, 1900. It comprises, essentially, a toothed wheel (P, fast with the hub or sleeve of the sprocket-wheel (Z a dog 71:, pivoted at k upon an arm l? of change-shaft l0, and a spring N, Fig. 2, acting upon said dog with a tendency to move the latter so as to carry its hooked or toothed end into position to become engaged by one of the teeth of the wheel (Z. The clutch-controlling means is similar in the main to that of the said Letters Patent N 0. 652,105 and comprises the rod 2" aforesaid, an arm '5 a rod 2* joined to the said arm, and a clutch disengager or controller 2, to which said rod is joined also, the said clutch disengager or controller being mounted to swing upon a vertical pivot m and pose of effecting a weft replenishment.

having an acting portion #yVhICh last is Yer tically ad ustable by means of a set-screw a.

the dog out of engagement with toothed wheel cl. WVhile it thus acts the changeshaft is stands at rest, it being held from accidental shift by means of the detent-lever 7c, Figs. 1 and 3, the latter having connected therewith the spring ls the said spring acting to hold the roll that is carried by the working end of the detent-lever pressed into an indentation which is formed in the periphery of the detent-disk fast on the change-shaft. When rod 7; is rockedas, for instance, under the, control of the weft-indicator devicesmotion is transmitted to the clutch disengager or controller, so as to move the acting portion 1:" thereof away from the tail of dog 70,

thereby enabling the spring k to throw the dog into engagement with the rotating clutchwheel d, whereby the change-shaft is set in rotation and the replenishment of the working weft-supply is effectuated through the operation of the instrumentalities which are provided for the purpose.

In order to facilitate the application of automatic weft-replenishing instrumentalities to looms which have already-been built and to enable such application to be efl'ected with a minimum of altering and fitting, I have provided amounting for the above-described changeshaft and its immediate appurtenances, said mounting being in the form of a separate stand or stands constructed to support the change-shaft and the movable parts or levers appurtenant thereto and adapted to be secured to the floor immediately beneath or adjacent a loom. In Figs. 1, 2, and 3 of the drawings, m is afloor-stand which is constructed and adapted as has just been stated. The said floor-stand is provided at m m with bearings for the change-shaft 7a and has attached thereto a bracket of, Figs. 1 and 2, provided with a pin or pivot m upon which the detentlever 7c is mounted. The floor-stand-also has attached thereto a vertical pin or pivot 122*, Fig. 3, to which the clutch disengager or controller is applied, as shown best in Fig. 3. At m m are upwardly-extending lugsupon the floor-stand m, to which lugs is applied the fulcrum or supporting rod on of the levers, hereinafter referred to, which are operated by the cams on the change-shaft for the pur- The use of the floor-stand mrenders it unnecessary to attach bearings, brackets, and the like to the loomframe for the support of the change-shaft and its more immediate appurtenances and enables said parts to be conveniently applied to looms which have already .been built without interference with the usualparts of such looms as such usual parts are at present constructed and arranged.

For the purpose of afiording time for permitting the weft-replenishing to be effected without undue precipitateness and violence I preferably, although not necessarily in all embodiments of the invention, provide means for suspending the picking for a predeter' mined number of movements of the lay. The

suspension of the picking may be brought tion in its more complete form I have devised the mode of enabling the picking to be suspended, which I will now describe. Having reference to Figs. 1, 2, 20, and 21 in the construction which is represented in such figures, the arm g with which the lug-strap g is connected, is not rigid with the picking rockshaft 9 as customary, but is pivotally connected at 9 to a block 9, which block in turn is' mounted upon a pin or pivot 9 projecting outwardly from the picking rock-shaft. The block 47 is capable of turning or swinging around the pin or pivot g in unison with the arm 9 in a direction from front to rear of the loom, while the arm 9 is capable of swinging in a direction transversely of the loom upon the pivots which connect the same with the block g An arm g bolted to the picking rock-shaft g is formed with an extension projecting outwardly from the loom end framea, the said extension having a recess at g, which is adapted to receive the arm 9 the said. arm being caused to occupy the said recess normally by means of a tension-spring g, which is connected with the arm 9 and also with a fixed portion of the loom-frame. During the regular working of the loom the arms Q31 and move in unison, and thereby the picking is effected. When it is desired to suspend the picking at the change end of the loom, the arm g is carried rearwardly out of the recess of the lateral extensiong of the arm 9 of the pick ing rock-shaft g Thereby the arm 9 is uncoupled from the actuating-arm and is not compelled to participate in the movements of the latter. For the purpose of drawing the arm 9 rearwardly automatically the said arm is joined by a strap'or other connection 1 to a lever g which lever is fulcrumed on the rod on and actuated by means of a cam 1 on the change-shaft 70. When the said cam acts to move the lever the arm 9 and block g are swung rearwardly around the pivot or supporting pin g with which the picking rock-shaft g isprovided. When the cam permits the spring to swing the arm g forwardly again, it reenters the recess g in the lateral extension Q32 of the fixed arm g on the picking rock-shaft The pickerstick-retracting device at g, Figs. 1 and 2,

acts with a tendency to hold the picker-stick g in its outer position, as shown in Fig. 2.

In order to permit the picker-stick to remain in this position while the arms and are uncoupled from each other, the arm g is pivoted, as at to the block r7 thereby enabling the arm g and block to swivel relatively to each other, (the arm standing at rest,)whi1e the block participates in the rocking movement of the picking rock-shaft that is occasioned by the action of the picking-tappet g.

In the present case the reserve supply of weft or filling is contained in a hopper or magazine at 02, mounted upon the breast-beam,

a supporting-bracket being shown at a attached to the breast-beam (L2 and carrying the magazine a.

For the purpose of making the transfer of the reserve weft or filling from the magazine a to the lay an injector or pusher 0 is provided, it being mounted upon an arm 0, which is pivoted to the loom-frame at The said arm 0 is joined by a connection 0 with a lever 0*, the said lever being pivoted on the fulcrum-rod m and actuated by means of a cam 0 on the change-shaft h. hen the cam 0 acts to move the lever 0* for the purpose of carrying weft or filling to the lay, it draws the arm 0 and injector 0 rearwardly to meet the lay. The arm and injector gravitate forwardly to their normal position again when permitted so to do by the action of the said cam. The arm 0 is provided with an adjustable contact-piece o to strike against a stop, as at 0 on the lay when the arm 0 and injector or pusher are moved rearwardly. For the purpose of enabling the arm 0 and injector or pusher to be moved rearwardly under the action of the cam until the contactpiece 0 encounters the stop 0 and of thereafter holding the said contact-piece pressed against the said stop while the arm and injector or pusher participate in the movement of the lay the connection 0 is made yielding and elastic. Thus in the present case the said connection 0 comprises a rod 0 which is pivoted to the arm 0 at 0 a similar rod 0 which is pivoted to the lever 0" at 0 opposite blocks o o having holes therethrough through which the pair of rods and 0 is passed, the said blocks having clampingscrews 0 0 by means of which one of the same is made fast to the rod 0 while the other is made fast to the rod 0 and a compression-spring 0 surrounding the rod 0 between the opposite blocks 0 0 I have shown the magazine a filled or charged with filling-cases 1). Suitable means is provided for regulating the feed of the filling-cases to the injector or pusher 0. Various contrivances may be employed for the purpose. I have herein represented a plate a, which is hung pivotally at n to the front of the magazine a and provided with a rear-, wardly-projectinglip at, Fig. 1. A spring, as of, acts upon the plate a and tends to hold filling-case supports, as 0 0.

the same pressed rearwardly into a position in which its lip a extends beneath the bottom filling-case in the magazine 22. and supports the same, together with the other filling-cases, on top thereof. For the purpose of moving the plate a so as to withdraw the lip 72. and permit of the descent of the filling-cases which are held back thereby the plate a is furnished with a projection of, extending into the path of movement of the injector or pusher 0. As the injector or pusher moves forward into its position of rest it encounters the projection M and presses the plate a forward, thus withdrawing the lip a, so as to permit the filling-cases to descend within the magazine n until the bottom one comes to rest upon The said filling-case supports 0 0 preferably are arranged to move in unison with the said injector or pusher and extend rearwardly thereof, as in Figs. 1, 2, and 3, or may be attached to the lay and extend forwardly therefrom, as in Fig. 24:, Sheet 9. When, now, the injector or pusher is moved rearwardly for the purpose of transferring the bottom filling-case from the filling-case supports 0 0 to the lay, the plate a is released to the action of its spring a, and the lip 11 thereof is thereby caused to pass beneath the next filling-case and support the same above the top of the injector or pusher 0 while the latter is in its rearward position.

When the filling-case supports 0 0 are arranged to move in unison with the injectoror pusher, the retraction of the injector or pusher forwardly into its normal or inoperative position after having been moved rearwardly to carry a filling-case toward the lay also carries the filling-case supports forwardly out of immediate proximity to the lay-beam. Should the said filling-case have failed for any reason to enter the shuttle in the shuttle-box, this retraction of the filling-case supports 0 a will permit the same to drop from the lay-beam. Thereby is obviated possible injury, such as might be occasioned in the advance of the lay by collision of said filling-case against the next reserve filling-case or other objectsin the loom or from said next reserve filling-case being carried rearwardly by a succeeding movement of the injector or pusher against a fillingcase lying at the front of the shuttle-box. In Figs. 1, 2, and 3 the filling-case supports 0 a are constituted by short rods fitted to bearings, as 0 0*, carried by the injector or pusher 0, and are capable of endwise movement through said bearings being kept from endwise movement by their frictional contact within the bearings. When the injector or pusher is moved rearwardly, the filling-case supports move in unison therewith until the rear ends of the said filling-case supports make contact with the lay-beam, after which the injector or pusher moves relatively to the said supports. In the return of the injector or pusher to its forward position the fillingcase supports move forward therewith until their forward ends encounter a fixed stop or stops, as at 0 which arrests them inproper position beneath the magazine 12; but the injector or pusher continues until it reaches its completely retracted position.

One of the filling-cases p is shown in detail in Figs. 9, 10, and 11, Sheet 4:, and the form of shuttle which is employed in connection with filling-cases like that which is represented in the said figures is shown in detail in Figs. 4 to 8, inclusive, same sheet. The body of the shuttle q, Figs. 4: and 5, is formed with an opening q of asize to containa filling-case 1), Figs. 9 and 10, the said opening extending entirely through the shuttle-body, as indicated in Figs. 4, 5', and 6, so asto enable a filling-case to be introduced at one side of the shuttle into the chamber which is constituted by such opening and subsequently to be expelled at the opposite side. WVhen in position within the opening or chamber g, the filling-case p is retained in place therein by detents. which in the present instance are constituted by V-shaped blocks (1 Figs. Lto 8, that enter correspondinglyshaped notches p 79, Fig. 10, in the ends of the filling-case The said blocks are fitted within the vertical slots 1 q of plugs q*, (see more especially Figs. 7 and 8.) which are inserted into the shuttle-body at the opposite ends of the opening or chamber (1. The blocks are held projected normally into position to engage with the ends of the filling-case by means of spiral springs 11 11 The said springs surround the stems q q of the blocks 9 Q2 and are confined within the longitudinal chambers Q7 g of the said plugs between the blocks and the inner ends of the chambers. When a filling-case is first pressed into the opening or chamber q of the sh uttle,the blocks g Q2 yield to the pressure of the end portions of the filling-case against their oblique faces, so as to permit the said filling-case to be forced into position within the opening or chamber q; but when said blocks have been caused by the springs g g to enter the nothes p p of the ends of the filling-case they serve to hold the filling-case in place during the movements of the shut- ,tle. They yield and recede also to allow the spent or failed filling-case to be expelled from said chamber in advance of the reserve filling-case which is being substituted therefor when the latter is pressed laterally against the former by the injector or pusher 0 as the said ends of said ends are also beveled off, as attrance to the chamber of the shuttle should not register properly with each other. In particular the bevels p p at opposite ends of the filling-case and the beveled shoulders g g of the shuttle-body at opposite ends of the chamber q are important, inasmuch as they enable a filling-case to enter the chamber q readily notwithstanding considerable misplacement of the shuttle longitudinally relative to the entering filling-case. This misplacement is due to the fact that the shuttle will not always stop at the same point in the length of a shuttle-box at the ends of its successive flights across the loom. At different times it will vary more or less in the position in which it comes to rest within the shuttlebox; The beveled surfaces'p p and (1 q coacting with one another will cause the en tering filling-case to adjust itself automatically and to properly find the entrance to the chamber (1', even though the shuttle may be misplaced considerably from its proper posi-.

tionthat is to say, the filling-case resting on the filling-case supports 0 0 and pressed rearwardly by the injector or pusher 0 is free to shift end wise relative to the injector or pusher as the inclined surfaces p p and q act against one another.

The weft or filling in wound form, which is carried by the filling-case. is contained within the chamber or cavity 19 of the filling-case. The manner of applying the said weft or filling to the filling-case and retaining it in place therein is not material to the invention. In the present instance the filling-case is adapted to receive weft or filling wound upon bobbins, a bobbin p being shown in position in the filling-case in Fig. 10, and for the purpose of holding the bobbin in place within the chamber 19 the filling-case p is provided with a U- shaped clasp p to receive and engage with the head of the bobbin. The means of holding the bobbin in place within the filling-case is not material to the invention. At 729 Figs. 9 andlO, is shown the yarn-delivery eye or educt of the filling-case.

The position of a reserve filling-case as it rests upon the fillingcase supports 0 0 pre- The ends of the yarns leading from the yarndelivery eyes p of the respective filling-cases within the magazine 02 are in practice attached to a suitable holder, which may be constituted by a pin, as if, Figs. 1 and 2, upon any suitable part in connection with the loom, the said pin being shown herein upon the magazine a. In order that after a fillingcase has been transferred from the magazine 01 to the shuttle on the lay the portion of weft which extends from the filling-case just introduced into the shuttle to the holder n may escape from the shuttle-box as the shuttleis picked, the front f of the shuttle-box is so contrived and mounted as to leave a passage 'f Fig. 1, between its lower edge and the upper surface of the lay-beam a Through this passage the said portion of weft finds its way when the shuttle is picked toward the other side of the loom. This passagef need be provided only at the inner end of the shuttle-box frontthat is to say, at the end thereof next adjacent the warp-although in the drawings I have shown such a passage at the outer end of the shuttle-box also. The said shuttle-box front is attached to arms a 6', extending forwardly from the shuttle-box back 6.

The shuttle-box backehas an opening therethrough, the curved ends of which are indicated in dotted lines at e e Fig. 3, to permit of the passage of the spent or failed fillingcase as the latter is forced out of the shuttle by the fresh filling-case in process of being introduced into the shuttle by the injector or pusher 0. p

A filling-case in being introduced into the shuttle by the action of the replenishing instrumentalities may in some manner be improperly positioned in the shuttle, so that it projects more or less at the rear side of the latter. For the purpose of insuring that the filling-case shall not thus project when the shuttle is picked and of properly positioning a filling-case which has been improperly positioned in being introduced by the action of the injector or pusherI provide a filling-casepositioning device, which herein is constituted by a rocker, the said rocker being journaled in bearings at .s" at the rear of the shuttle-box and having a wing or wings s 8 adapted to make contact with the rear side of a filling-case occupying the chamber q of the shuttle in the said shuttle-box. The fillingcase-positioning device is placed under the operative control of the change-shaft through connections, which in the present instance comprise an arm s on the said rocker, a rod 5 joined to the said arm 8 and a lever 8 to which the said rod 8 is also joined, the said lever being mounted upon the supporting-rod m and engaging with the cam s on the change-shaft. The said cam is shown separately in Fig. 13, Sheet 1. Under the control of the portion 8" of the said cam the rocker moves so as to press its wing or wings a forthe rearward movement of the spent or failed" fillingcase after being ejected from the shuttle. The rocker is moved into this position -by means of a tension-spring a, connected with the rod .5" and with the lay-beam. respectively.

In order to avoid injury in case the movement of the positioning device is obstructed, a yielding member, as s, is introduced into the train of operative connections. This yielding member, herein constituted by a compressionspring, yields to the continued movement of lever 8 when the positioning device is prevented from completing its forward movement, and thereby obviates straining or breaking of the parts. The use ofthis yielding memher also renders unnecessary delicate adjustment of the parts in order to secure accurate working of the positioner. The extreme forward position of the positioner is determined by means of a stop 8 Fig. 12, against which one 01' both of the wings 8 makes contact. After such contact occurs in the forward movement of the said Wings the spring at 8' yields to any remaining portion of the continued movement of the lever 8 The cam s,

by means of which the positioner is operated,

is formed with a portion, as a, by means of which the positioner is caused to assume at the time of the expulsion of a filling-case from the shuttle in the shuttle-box at the change end of the lay an intermediate position in the path of the said filling-case. Thereby the said iilling-case is arrested as soon as it has cleared the shuttle. By this means not only is the expelled filling-case prevented from being driven too violently away from the shuttle, but the said filling-case is arrested in a position to cause it to serve as a stop by means of which the entering filling-case is prevented from being driven too far through the shuttle-body at either or both ends of the filling-case by the action of the injector. I thereby provide against either lateral misplacement of the filling-case in its entirety within the chamber or cavity of the shuttlebody or the projection of either of the ends of the filling-case at the rear side of the sh uttlebody. The portion a of the cam 8 permits the positioner to assume its entirely-retracted position, in which latter the wing or wings s are withdrawn from the path of the expelled filling-case. The latter rests upon the supporting-guides 0, Figs. 1 and 14, projecting from the lay at the rear of the shuttle-box, and after the withdrawalof the wing or wings s the said filling-case is caused by the movement of the lay to pass rearward along the said supporting-guides and from the same onto the shelf a), which is suitably attached to IIO the loom-frame. porting-guides o work in slots o o in said shelf, as shown best in Fig. 14.

At the front of the shuttle-box at the change end of the loom the edge of the lay-beam isrounded off, as at Z), Fig. 12, Sheet 1, in order to facilitate the transfer of a filling of a filling-case from'the magazine a to the shuttlebox and prevent the lower portion of the filling-case from catching against the edge of the lay-beam. Therounding off at this place also facilitates the dropping of a filling-case which has been transferred to the lay but for any reason has been prevented from entering the chamber or cavity of the shuttle on the Pay.

It may sometimes happen that a filling-case after being introduced into the chamber or cavity of the shuttle in the shuttle-box at the change end of the loom may project more or less at either the front or the back of the shuttle at one end of the filling-case. For the purpose of insuring that a filling-case which thus projects shall be restored into proper working position in the shuttle I bevel the shuttle-box front and shuttle-box back at the ends of the openings therethrough, as at f f e e Fig. 3, so as to form inclined surfaces which by their action against projecting portions of the filling-case will operate to force the filling-case in, so that its sides shall lie flush with the sides of the shuttle-body.

I mount the swell or binder t above the top of the shuttle-box on a horizontal pivot t",

Figs. 1 and 24, so that it swings in a vertical plane and bears against the upper side of the shuttle. A protector-lever t is pivoted at t upon a bracket t*,projecting rearwardly from the lay. The forwardly-extending arm of the protector-lever rests upon the topof the swell or hinder t, and the rear arm thereof is connected, by means of a rod t ,'with the rearwardly-extending. arm t of the protector-shaft t the latter being provided with the usual dagger t", Fig. 2.

For the convenience of the weaver a container or receptacle, as a, Fig. 1, may belocated adjacent the loom to hold a quantity of filled filling-cases and from which the magazine 72 may be charged by the weaver when necessary, or the said container or receptacle may hold wound filling 1n readiness to be introduced by the weaver into empty fillingis a deficiency in the supply of reserve filling I provide a detector w, Figs. 1, 2, 3,'and Figs.

15 and 16-, Sheet 5, which acts in connection with the contents of the magazine, and with the said detector I operatively combine knocking-olf devices and other coacting parts by means of which the driving power of the loom is unshipped when the detector indicates de- The rear ends of the supficiency of reserve filling in the magazine.

Preferably I arrange so that the devices just referred to shall act to stop the loom before the last charge of reserve filling has been transferred to the lay, and to this end I arrange the detector so that it shall be controlledby the reserve charge of filling next succeeding the one which is in readiness to be fed to the lay by the injector. Reference will now be had more particularly to Figs. 15 to 19, Sheets 5 and 6. In these figures the detector 10 is shown in the shape of an arm mounted upon a rock-shaft 1/), supported in bearings 102 10 from the breast-beam a The said arm is shaped so as to extend upwardly from the rock-shaft 20, then forwardly over the breastbeam, then outwardly toward the end of the breast-beam, and then rearwardly, so as to enter an opening at the front of the magazine a, the end of the said detector being adapted to take bearing against the filling-case which is next above the filling-case resting on the supports of the injector 0. (See Figs. 15 and '16.) The rock-shaft w is acted upon by a light spring 20 Fig. 17, tending to move the detector w rearward] y. Thereby the detector is pressed against the filling-case that is in line with its end, as in Fig. 16, and when there is no filling-case in line with the said end, which will occur when the last filling-case in the magazine has descended onto the supports 0 0 the spring causes the detector to move rearwardly into the position which it occupies in Fig. 18.

For the purpose ofbringing about the unshipping of the driving power an arm 10*, Figs. 15, 17, and '19, is attached to the rock-shaft M at the driving end of the loom. This arm extends upwardly beneath a hunter 20", which is pivoted at w to the inner end of the knocking-off lever 10 the latter being pivoted at 208 at theouter end of the usual bracket w for the shipper-handle 10 Normally-that is to say, when the feeler w is held forward by a filling-case inline with its end, as in Fig. 16 the arm 20* takes a position in which it sustains the hunter Q above the path of motion of a suitable going part. In the present case the lay-beam Z) carries a striker Figs. 17 and 19, that is adapted to cooperate with the said hunter 1.0 When by the absence of a filling-case p from in line with the end of the detector w the said detector is permitted to move rearwardly into the position which it occupies in Fig. 18, the arm 20* also moves rearwardly, (see Fig. 19,) lowering the hunter 20 into the path of motion of the strikerw.

In the next succeeding advance of the lay the the picking rock-shaft g is provided with picking-arm g of usual character rigid therewith and having the inner extremity of the lug-strap g connected thereto in usual manner. The outer extremity of the said lugstrap is connected with the arm g, the latter being pivoted at upon a lever with capacity to swing in a direction from front to rear in the loom. The lever g' in turn is pivoted at 9 upon the support 5 upon which the rocker g of the picker-stick g is mounted. Lever g is arranged to swing transversely of the loom upon the pivot g. Arm g is provided with a shoulder at g to take behind the outer side or edge of the pickerstick g, as shown in .Fig. 22, and from an outward extension or horn g, which when the said arm g is disengaged from the pickerstick bears against the rear side of the pickerstick g and guides the arm g in its movements, so as to facilitate the subsequent reengagement of the said arm with the pickerstick. This horn g corresponds with the similar outward extension of the portion of the arm of the picking rock-shaft which is shown in Figs. 20 and 21. The arm g is connected by the strap g with the lever 7 operated by cam on the changeshaft k, and when by the action of the said cam the lever is moved so as to draw the arm ,r rearwardly away from the picker-stick into the position in which it is shown in Fig. 23 the arm is disconnected from the pickerstick. If now the picking rock-shaft is oscillated by the action of the picking-tappet the parts g and g will turn in unison upon the pivot at g, but without operating the picker-stick. A spring 9 serves to carry the arm g toward the front of the loom again when permitted so to do by the cam and when this spring is permitted thus to act the shoulder 9 passes forward outside the outer edge of the picker-stick g after the parts g and 9' have been swung outwardly by the action of the picker-stick-retracting spring g.
