To all 1vol/1,0711] it 'n1/rtg concern:

Be it known that I, JONAS Nonrnnor, a citizen of the United i. tates, residing in Hopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of 'l description, in eonnecwhich the following tion with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to that type of loom wherein the running filling is replenished au- `tomatically and wherein two filling-detectors .either fork.

A loom of this generalcharacter forms the subject-matter of United States Patent No. 789,291, granted to me May 9, 1905, the replenishing mechanism therein shown being of the well-known Northrop type, 'wherein the running shuttle islprovided automatically with a fresh supply of filling whenrequired; Such filling replenishment may be called for prior to complete exhaustion of the filling in a feeler'v-loom, orit may be called for upon failure of the filling-,that is, when or by breakage fails or is absent when thev detecting action of the detector occurs.

In my present invention I ani dealing gi'ore particularly with non-feeler looms, wher n a change in the operation of the loom-such as -lshing'side 'of,the loom. Such anarrange--` rboth-is effected .failure or absence.

filling replenishment or loom stoppage, or automatically upon filling In United States Patent No. 691,481, granted to Ine January 21, 1,902, a loom is shown provided withmeans to effect filling replenishment on the pick on whichfilling failure or absence i's'detected, the detection of the presence or absence of the filling taking place on the'pick ofthe shuttle to the replenment provides for immediate replenishment of the running filling, if the latter fails on the pick toward the no arrest of the take-up is required. If,

however, the failure takes place on the opporeplenisliing side, and hence site pick, detection of such failure is not made i until thevnext or detecting pick, and hence there will be two picks in which the filling is improperly laid, and if take-up is not arrested for those picks a thin place will be made in the cloth. l

My present invention has for its object the production of a loom so constructed and ai if 'f ranged that Atake-up 1s arrested when necesn sary to prevent the formation of thin places in the cloth, and filling replenishment is effected upon detection of filling failure, and in the practical embodiment of my invention herein illustrated and described such replen- -ishment is effected on the pick on which fail ure is detected-viz., on the pick toward the replenishing side of the loom.

I have herein provided two filling-detectors to detect on alternate picks, one detector controlling the replenishing mechanism and the other detector controlling the takeup mechanism, and I have so arranged the apparatusthat when take-up is arrested by or through detecting action of its controlling; detector take-up will not be resumed until such detector indicates the proper laying of the filling.

The mechanism for carrying out my invenc tion is simple anddirect in`action, and ce'r -tain valuable features inherent in the struc-- tures embodied in my patents hereinbefore referred to are also comprehended herein in a novel and efficient manner.

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

I have illustrated tion with filling replenishing mechanism of the Northrop type, the same as shown in the patents referred to, thou-gh my invention is not restricted thereto, as will appear more clearly hereinafter. i

. Referring to Fig. 1, the lay A3, shuttleboxes B BX thereon, the shuttle SX of an aurepienishing mechanism at the looin side adjacent-the shuttle-box B and including' the trilling-feeder F, (only a portion of' the latter l being showin) and the transf'eirer F to transfer the i'illing carriers or bobhins b, Fig. 3, trom the leeder to the shuttle, to therel'iy replenish the supply of running idling', the stud Fi", on which the transierrer rocks, and thc retracting-spring F' ior such trans'i'errei', may be and are all sulistantialifY as common in the Northrop type of looinsuch, .for instance, as shown in United, States Patent No. 529,940, dated November 27, 1894i.

llerein the ti'ziiisl"i\iier is provided with a short ielepending extension 17 which carries a notched dog 2, Fig. 3, to be at times eiig'aged by an actuator shown as a bunter 3, fast on a short rock-shalt fi, inoui'itcd in a sleevedike hearing .5 on the lay, said rock-shaft having at its inner end an upturned short arm or trip (i rigidly secured to it and adapted to he moved rearii'ardly into the clearance '7, F ig. l, at the inner end or mouth oi' the replenishing--box BX. i

A spring f), connected at its ends to the roel -slia-lt and to the bearing' 5, respectively, is so wound as to normally maintain a slioulder i() oitlienctuator or hunter 3 on a stop l1, herein shown as 'forming a part oi the hearing-casting The actuator or bunter when in such position is so held as to traiiel below and ciear of the dog 2 in the normal operation ofthe loom.

When the short arm or trip (i is swung' rearwardly against theaction o'l'spring 9, the actuator or buntei' b will be `thereby lil'ted into position to ei'igage the dog' 2as thelay beats up, and as the beateup is completed tlu` transierrcr F will be depressed, to thereby insert a fresh filling-carrier into the shuttie then in the replenishing-bini BX while the iiling-arrier then in the shuttle will be.

'l'ected by or through detection of [illing failure by one oi' the two filling detectors or i'orks with which the loom is equipped and vin such manner that the replenishing mechanism will be actuated. on the pick on which such filling' failure is detected. 'and indicated: The two filling-deteetors are shown ,in plan view in Fig, 1, and it will be seen that they are located at opposite sides of the looin, and in the present embodiment of my invention the operation of the replenishing mechanism is controlled Wholly by the righth'and detectorthat is, the one at the saine side o'i the loom-and this detector and the mechanism coperating therewith will now be described.

A substantially L-shaped support 12 13 is rigidly secured, fis-hy bolts 14,v Fig. 2, toia 4'bracket-15 on the front'of the 100m and back of the breast-beam A4", the part 13 oi the support being extended rearwardly and in a suhstantiallyhorizontal direction, and, as shown in Fig. 10, said part is bifureated to form a 'fixed supporting' means for the filling detector IIC grids. fork vwith the grid when upon filling failure l or fork 16, fulcrumed at 17 to tilt or rockin a manner common to filling-forks.

One of the tines', as 16X, of the fork is prefl erably covered with felt, flannel, or other 'ction-indueting material to enable the fork to have a better action when engaged by the filling. This fork is located opposite the grid or grating 18 on the lay adjacent the mouth of the re lenishing shuttle-boxl' and referring to Fig. the upper end of the to a grid is, bent rearwardly This prevents any engagement of the to Fig. is at front of the grid center the upright front portion or grating is Well in front of the fulcrinn 17 of extension 19.

' prising an' upturned `fork is in untilted ordetecting forward the fork. Said fork is provided with a forward extension or tail 19, which at times serves to lock in operative position the controlling device to'be described, and whereby' when the device is so locked the actuation of the replenishing mechanism will be effected. .transverse pin 20,'between the bifurcated sides of the part 13 of the fork-support, has mounted. upon it a sleeve-like hub 21, Fig'. 10, of the Icontrolling device, the latter eing shown as a species of bell-crank cornmember 22and a slightly depending and fo wardly-extended member or foot 23, the latter normally lying below. the support, .as shown in Figs. 11 and 1.2, while the upright arm or part 22 is located in front of the path of movement ofthe fork The rear face of the said part 22 ,serves at times as a shoulder against which abuts the free end of the extension 19, as shown in-Fig. 11, and at that time the position, and when the controller is so locked-it will be clear that it cannot be tilted or rocked on its fulcrum- 20 in the direction of the arrow $.24. Movement of the controller in the opposite 'directionl is limited by a stop 25 formed on one of the sides of the part 13 of the forks'pfrt.

y '111e foot 23 is laterally offset to swing in a vertical path outside of thehorizontal portion of the fork-support,y as will be clear from an inspectionl of Fig.10, d such foot is normally in th'e path of movgiient of and adapted to engage the short arm or trip 6 on each eat of the lay.

If the controller is locked in its normal position, as in Fig. 11, when the lay beats up, the trip as it cornes forward engages the under edge of said foot 23, and as the foot cannot give the trip is pushed backward into the clearance 7 a ainst the action ofthe spring 9, rocking the s aft 4, and thereby moving the actuator or bunter 3 into operative p tion to engage the dog 2 and eifeet'filling re. en-

completed.

greater extent than is usual in forku l l from engagement It will be noted in Figs. 11 and 12 that the i under face 23 of the foot is forwardly and downwardly inclined to assist in such swingg ing movement of the trip.

Ifthe controlling device is unlocked-as, ,i for instance, in Fig. 12`the trip 6 will wipe along the lower edge of the foot and'will l slightly rock the controlling device on its fulj* crum 20, so that no change in the relative position of the actuator or bunter 3 will take l place, and at such time no operation of the replenishing mechanism will be efl'ected.

lVhenever the detector or fork 16 is tilted, Whether by engagement with filling or otherlwise to withdraw the locking Aextension 19 with the controlling de l vice, the latter is free'to be rocked or turned l in the direction of the arrow 24, Fig. 11.

The upper end of the part 22 of said conj trolling device is prolonged upwardly and i' forwardly to present an inclinedv face 26 for 1 a purpose to be referred to. l A cross-bar 27 on the fork-support serves l as a stop to limit downward movement of the locking i extens1on 19, Figs. '10 and 11, and just in front of said stop or cross-bar isy fulcrumed at 2S a depending finger 429, having |an eccentric weighted head 30,- the latter I serving to normally maintain the finger in the position shown in Figs. 10, 11, and 12, I, the finger being so located that`when the lay beats up and filling is present to tilt the fork the finger will prevent such filling from passing under the tines as thelay reaches front The cooperation of the' finger and fork is well shown in Fig. 12, the finger at such time j passing between two of the fork-tines. The

l cross-bar 27 serves also to limit rearward l swing of the finger, which may be saidto act as a guard to prevent movement of the thread under the tines of the fork.

l The fork 16 detects presence or absence of filling on every alternate pick, such picks being those on which the shuttle is moving toward the replenishing side of the loom, and

l detection takes place on the forward beat of the lay after the shuttle has passed beyond the range of such fork. l

It vfor any reason the shuttle should not be properly boxed, but` should. project far enough from the mouth of the shuttlebox to strike the fork, the latter will be tilted, thereby preventing any operation of the replenishing mechanism, andas the fork 'is perl fectly free to tilt no injury will result thereto. This tilting of the fork by the shuttle when .imprperly'boxed enables the fork to also I aet asa shuttle-feeder', because even if the filling should have failed the replenishing mechanisml cannot operate if the fork is I, tilted. 4 I

When the-filling -fails on thedetecting-piek of the fork 16, the-latter will not be tilted as i the lay beats up, and the extension 19 there- ICO return-piek or othei.\'ise and at the same time the foot ylatter is on its return-pick,' leaving the box l, and l have provided means to positively tilt the lork on such return-pick, to thereby withdraw it from the' slmttlpath, and such means are also made effective to prevent. any detecting action whatever of the fork on the mechanism would be operated ou each of such returnpi .:ks, as will be manifest.

The fork-head is provided with an upright transverse projection 31, lying' in the path of movement of the lateraily-extended end 32 of a vibrating member 33, pivotally mounted. at 34 on the upper end of a cani follower or vibrator 35, suitabl' \Y fulerumed at 36 on the loom-l`ramc and actuated b v a cam 37 on the (1am-shaft 3S. The vibrating member 33 is provided with two depend ing guides 3Q 40, which straddle one of the sides of the part 13 of the 'fork-supjmrt, and the free rear end of said niei'nl'ier 33 slides on the top of such side, so that as the vibrator 35 oscilla tes the member 33 will move forward and back along' the substantially horizontal top of the support. At the outer end of its stroke'the'vibrating member 33 is in the position shown in. Figs. 1, 2, 1.0, and 11, the lateral extension 32 being then just in front-of the projection 31 on the fork. The inner guide /10`is provided with a lateral lug 41, movable in a path above the stop 25, hereinbefore referred to. The cam 37 isso shaped and timed that the member 33 begins to move rearwardly just as the fork is about to'detect presence or absence of 'tilling failure and reaches the position shown in Fig..12 at the time the ,lay reaches front center. The lateral extension 32 is thereby brought against the projection 31, and the fork is -held in the tilted position shown in Fig. 12, and as the vibrating member 33 'com pletes its rearward stroke the fork is tilted an additional amount until the extension 32 wipes over the projection 31, as in Fig. 13, practically releasing the fork. By this time, however, the lug -11 has moved into engagement with the controlling ,device and has tilted that intothe position shown in Fig. 13, moving the incline 26 to the rear, so that the fork extension'lf) drops thereunto; but it can only drop to the position shown in Fig. 13, maintainingr the fork in a tilted position, 23 is lifted into inoperative position.

When the vibrating member 33 tilts the fork, as described', the shut-ole is free to be picked from the replenishing-box and will be shot across the lay Without any possibility of interference with the fork, and When the the replenishing l l i l l l parts assume the position shown in Fig. 13 it will be manifest that as the lay beats up the vfilling on such return pick replenishing mechanism can be effected by or through. the Jfork, for the latter is somewhat tilted and, furthermormthe controlling device is in an inoperative condition. The shuttle is non picked from the .non-replenish.- ing box B, and the fork 16 must be in detecting` position by the time the shuttle has passed the grid or grating 1S. To this end "the vibrating member 33 is moved on its forw ard stroke, and. durin this stroke the movement of the lug 41 allows the controlling device to gradually resume its normal position, the extension 19 sliding down the incline 26 toward locking position. andv at the same time the lateral extension 32 on the member 33 wipes over the curved edge L12 of the pro jection 31 on the .fork and acts to positively return the fork to detecting position, the latter being shown in Fig` 11. ellected before the lay reaches the detectingpoint on .its forw ard be at.

The incline 26 fork 1) also provides for the tilted fork to detecting position, and thereby obviates any improper jumping or vibrating of the fork, and this function is also enhanced by decreasing the distance which the extension'must drop from its highest point before being engaged by some stopping part.

On every detecting pick it will be observed that the fork which controls the operation of the replenishing mechanism is in detecting position and the controlling device is locked in its operative position, and it will be also observed that on every return. or non-detecting pick such fork is positively tilted, and through the means described there is no possibility of the replenishing mechanism being operated on such pick.` The positive tilting of the fork onsuch intervening picks is also timed to enable the fork to clear the' outgoing shuttle from the replenishing-box BX-.i A suitable spring 43 acts upon the vibrating member 33 to depress the latter and prevent any im roper jumping in its movements,

As filling is replenislmd on the pick on which failure is detected b v the fork 16 takeup is not arrested, nor should it be; but l have provided means for arresting take-up if the filling fails on the return picks-that is, the picks of the shuttle away from the replcnishing side pose I have provided the second illing detector or fork, the function thereof befng to control the take-up mechanism and to arrest and. maintain arres'ted the taking up f the cloth while the iilling is absent. on thee etceting picks of such takcarp-controlling detector.

The take-up mechanism herein. illustrate-d is substantially that shown and described in United States Patentito Roper, No. 307,530,

a gradual return of no actuation of the.y

This return is all' b v its cooperation with the of the loom-and for this pur.

dated December 19, 1905, the take-up roll T j being connected by a train of gear t t t2, with i a worm t3, operatively connected with a rotal table shait t, on which is loosely mounted a driving member, shown as a sprocket #,whieh in practice is continuously rotated from some moving part o1 the loom, as in the Roper patent referred to. A suitable clutch at t6 normally connects the driving member t and the shaft t4- to rotate the latter and opcrate the take-up mechanism, a spring t7,

ig. 5, maintaining the clutch operative.

Herein I have provided a clutch-controlj ling arm 44, i'ulcrunied at 45 at thevfront ol" the loom and having a depending yoke-like portion 46 to coperate with the clutch, the

As in my Patent No. 789,291,`a latch-caris herein shown provided with a to at times cooperate with the adjacent end of the knock-off lever NX, vfulcrumed at nX, such cooperation rocking the knock-oil' lever and releasing the shipper S, Fig. 1 from its usual holding-notch in the The latch-carrier cooperates with 12 13X, as in this patent, to thereby effect stoppage oi the loom if the slide. 50 is moved outward a predetermined number of times insuccession to -tliereby stop the loom in case of shuttle-misthreads that is, if after filling re lenishment the shuttle tails to thread the 'f ling will be broken on the pick toward thereplenishing side and another supply of filling will be inserted in the shuttle. It the misthread be due to clogging of the. parts, the mechanism just describe stops the loom after a predetermined number of replenishments in order to avoid. emptying the hopper or filling-feeder unnecessarily.

inoperative, ar-

resting 4taleaip, and such outward move-1 ment of the slide 50 is eiected when on the pick toward the non-replenishing side or the loom the rork 48 detects iiliing iailure.

ln Fig. 7 the fork has not been tilted, and the weft-hammer hook w has engaged the fork-tail 49, and the slide has been movedl forward by the forward stroke of the weithammer W. By inspection of said ligure it willA be seen that the take-up-controlling arm 44 has been moved into position to release take-up. l have herein provided means to prevent resumption ot take-up until the fork 48 thereafter detects presence of filling and the device by which arrest of take up is maintained, as shown in perspective in Pig. 9. This device consists ot' an elongated body 55, having its iront end enlarged and laterally extended at 56 to present an' elongated vertical face 57, the part 56 resting upon the extension 52 ot the slide and being retained in position .thereon by a pin 58, which projects into the longitudinal slot 53. At its inner or rear end the body 55' is enlarged and downturiied to present a lateral upright abutment 59 and a guide 60, the. abutment and guidestraddling one side vof the stand 51 and the adjacent side of the slide 50, as shown in Figs. 6 and 7, the clearance 61 between the abutment and the guide being wild enough to permit such positioning of the device. A lateral lug 62 on that side of the stand 51 eX- tends in front of the guide and limits forward movement of the device. (Shown separat-ely in Fig. 9.) The abutment 59 lies in front of the weft-ham mer path; but nor ally the hammer will not coperate therewi h, as will be clear from an inspection of Fig. 6.

When the fork 48 detects 'filling failure and the slide 50 is thereupon moved forward, the position of the slide and the device just described is changed, the slide moving forward, as it were, underneath such device, so that the pin 58 will lie in the rear end of the slot 53, as in Fig. 7, and the straight edge 57 of the part 56 will form va continuation of the vertical face 50 A of' the slide. The .connection 63 between the gdide 6() and the abutment 59 then drops into a notch 64 on the slide. Upon the outward movement ofthe latter the arm 44 is pushed to the left by the 1 15 camr54 and rests against the face 50X, and

IIO

were it not for the maintainingdeviee (shown separately in Fig. 9) the arm 44 would return to normal position as the slide moves back.

As the slidemoves back it carries with it the 1 2o maintaining device, and the face 57 then engages the arm 44 and maintains it in its inoperative position,s o that the take-up clutch t 'If the fresh filling is pro erly laid on the return pick, its'presence 1 2 5 is tliien detected bythe fork 48, the latter be- A ing tilted, and as the weft-hammer W moves forward it engages the abutment 59 and moves the maintaining device forwardwith relation to the fork-,slide into normal po- 13o loo ' permit the fresh filling to bei laid freely and in sition, (shown in l1`ig.t` ,)therebyreleasing the t arm tft, so that it returns to its normal position and take-up is resumed.

The front head ut7 of t the arm -t4 projects over the lateral enlargement 5o ofthe maintaining device and serves toretain vit in position on the slide, preventing it from jumping;` up or heeoming iii-isplaced.

The device tor maintaining thc arrest ot take-up does not interfere at all with the proper operation of the mechanism for effecting loom-stoppage when misthreading takes place, one operates entirely independently of the other.

Then the slide 5t) is moved'forward, the pin tjl holds the maintaining` device stationary, and it also serves as a stop to limit: for- Wa'rd movement of the device when the abutment 59 thereof is engaged by the weft-hammer to reset it.

The talre-up-eontrolling detector or forli detects on the picks ot the shuttle toward the non-replenishineside of the loom, so that thc two forks detect on alternate picks.

The lifting' or tilting of the fork at the rc plenishin') side by the positively-acting means described serves when tilting' is replenished to proper position. under and back of the fork whenthe shuttle is pielred from the. hex Bi" at the rei)lenishiiig side, so that there is no possibility oll the fortegettingl behind such idling. So, too, it will be 'manifest that as such positive raisingof the right-hand fork takes place inst at'ter intact tilting has tilted the fork initiall)Y the action upon the lilling; is -very light and tlelieatewwthat is, as soon as the initial tilting has heen etl'eeted the l'orh is withdrawn from the tilting, so that an \Y strain thereupon due to fork aetion is minimized and the deli aey of the detecting' action is thereby increased. 4

My invention is not.restrieted to the particular l'orm ol' ta,l\:eup mechanism herein shown, although the latter is well adapted for use in eoi'meetion with my invention; hut it will be manifest that any other form of tali up mechanism ran he employed so lon; as it. is controlled by the adjacent tilting-forli, and take-upmaction when arrested is maintained arrested, as herein provided for.
