Be it known that l` .loxpw Noarnnor. u citizen of the l'niteil Staten. residing at llopeilale. in the eount)v ol' lVori-ester unil Stato of Masnarhusetth. have invented eertnin new and useful improvements in Feeler Looms: and l lo herehy declaro the following to he a full. elear. ainl exaet le Seription of the invention` sui-l1 :is will enlU ahle others skilled in the arl; to which itI appertains lo make and une the Saule.

The present invention relates to an nnprovenunt in looms. anel more pariouhirly the` invention relates to un improveninnt in l5 Center fork filling tletoftor mechunirnn for looms.

The invenl ion is partieularly adapted for application to feeler looms whirh ure a type ol automatic weft replenishing loom in whieh the higher grades of fabrics are woven. Such looma` are provided with a filling feeler mechanism which measures the amount of fillinLr in the active Shuttle, and when the filling' has heen exhausted to a` oritival or preilelerminefl extent. Caunes the weft wplenishingl nieehaniein to innert a fresh supplyY of fillingV in the shuttle. The. employment of the filling freier mechanism to eontrol the operation of tho weft re plenishing mechanism is for the purpose of avoiding the preseneo of short wefts or niis'pieks in the woven fabrica In oase the filling should@ become eon'lpletely exhuuteil. owing to a llefeetirro filling: fehler action` or in eine the fillingV Should hreak. the loom is stopped hy the nothin of a fillingleiht tor mechanism with whirl] fehler loon` aro usually l'noviilerl. lf the filling lli-oler ||u-i-hnnisin is loratrll al` either eoil of the loom, that is to my. `hes'ule either selvagge. broken oefts are liable to he ivoren into the cloth and lieJ unileler'lell hr these filling lletevtor morhanirmn. Areorilingly feeler looms are often provided with a fillingr letertor lnerlninism in which the fillingr fork is mounted on the miilille ofthe luy. These forl perform their filling; ilelorting operations on every heatvup of the lay and rauw loool stoppage in ease the filling;` Shonhi he, ahwni from the nlielille of the Shefl. l. Luh filling (lolertor uwehauiiins are known in the art as renter fork filling (letali-tor meel'uinhqns.

Ono ohjert of the prraent inilentisln is to produce :i center vforli filling ileteror meehanism ol such eontruction that when the filling forli performs. its llinp; detecting operation. it is entirely1 lliseonneuteil from ilsy actuating; means aurl descends upon the fillingr with only the force of the alesrenlling fork linee. The filling ileteeting operation in therefore very Sensitive :unl the filling or weft is, not Stretuheil or otherwise injured hy the action ofthe fork tines.

A further ohjeet. of the invention is to produce a renter fork filling leteetor meehanisn] whirh will he rendered inoperative or funetionloss on the iii-St heatfnp of the lay alter the weft. replenishingf operation. The reason for reusloring the fillingr detector nnwhunism inoperative on thisl heal-up isv heeause the enil of the new filling: :xtturheil to ilu hopper stud ainl the filling pajv out from the hohhin over the niitltlle of the eye or delivery end of the Shuttle. and consequently relatively near the reed. This laying of the filling relatively near the rewl on the first piek of thu Shuttle lifter tho replenishingl operation results in the renter filling fork, often failingr lo dotnet the )neoeneo ol' the` filling` because of the ful-t that the filling is beyond the end of the forli tiueS. The enfl of the fork tiuesl is noressnrily Separated from the reed a ronsiilerahlu iliutanee because of the construction of the lay ainl the reed at that point. By reinlvring the fillin r detector mecha.- nism inoperative or funetionless on this heat-up of the lay. the possibility of the fillinglr fork missing the newly inserted lilling. aull r-.onsoquently Stopping the loom. is ohrinteil.

A still further olijeet of the invention is to prollueu :i Venter fork filling detector niveluinisni of suoli .-i'intrurtion that` it is renilereil inoperalive or functionless on the first heabup of the lay when the loom is re-Startuil :ifter the stoppage thereof. This rendering ol' the filling` rloteetor mechanism inoperative or functionless at this, time is malle never-sary hy the fact that it is universally the custom 'among operators when the. loom is stopped for any reason. to turn the loom over hy hand, in order to remedy the lll-feet musing the stoppage. lt' the loom is stopped heeause of warp hre-akelige. :i filling,Y will generally he present in the shed aS the lay :uli/:inves ou the beatup on which the loom is usually Stopped. Consequently. when the operator turns the loom over the filling and the center fork will frequently be disengaged from each other so that the fork will fall into itsrecess, and therefore when the loom is started up again, it will immediately be stopped because of the fact that the fork is in the position it assumes when filling is absent.

Another object of the invention is to produce s center `fork fillin mechanism in which the time o the rising and falling movements of the fork are citpable of relative adjustment. In turning a oom over by hand the flight of the shuttle occurs et a higher s eed relative to the movement ofthe luy t an when the loom is being operated by power; that is to say, the Hight will be completed before the ley hns travelled its normal distance away from the fell. For this reason, the shuttle Will sometimes strike the fork, bending the tines and causing injury to the febric when the loom is turned over by hand. Therefore it is desirable that the time of lifting the fork Shall be so ad'usted as to occur on the Inovement of the iay to the rear as soon as the tines will ciear the fell. The time at which the fork drops, however, should not be affected by the adjustment of the time at i which it is lifted.l

The feeler loom to which the features of the present invention are applied'may be of any usual or preferred form. 'ln the type of feeler loom illustrated in the drawings,

detectof theltiiling fceler mechanism indicated genera l attac led to one end of the breast beam 12, und the weft replenishintglr mechanism, indicated diugrammuticully nt lV. R. M. in Fig. 11, is mounted on the other end of the breast beam. The two mechanisms are operatively connected by a hollow rock or change shaft 13 which is journaled in brackets on the front of the breast been] l2 und extends longitudinallyl thereof. The function of the filling feelcr mechanism is to determine the state oi' exhaustion oi' the filling: in the active shuttle. iVhen the filling has been exhausted to u prcdcterminul extent. the fcelcr member ll swings contral-clockwise, viewing Fig. l, under the propulsion of a springi which is interposed between u change lever 1G (pivotcd ut 1T on un urin I8 secured to the change shaft 13) and a latch lcier 19 pivoted :it 20 on the change lever 16. The fecler member 14 und the latch lever 19 arc connected by a link 21. The contrai-clockwise swinging of the feeler member l-i und thc latch lever 19. viewing Fig'. l. moves the notched end 23 of the latch lever into tbc path of movcrncntof the weft hummer :24. und thereuprm. owing to the forward movement of the change lever 1li, the arm 18 and the change shaft 13 are 'oscillutcd to initiate the weft replenishing' operation.

As is usual with feeler looms. the loom is stopped on the detection of filling absence. The loom stopping ineens comprises the shipper 25 which, when the loom is operating, is thrown forwardly against one end of n shipper or knock-off lever 26 pivoted at 27 on n bracket extending outwardly from the breast beam. lVhen filling absence is detected by the center fork filling detector mechnnism constituting the subject-matter of thepresent invention. the shipper or knock-oil' lever 26 is caused to turn clockwise, viewing Fig'. 1. thereb),v knocking oil' the shi per 25 und stopping the loom. The parts a ve described. together with the lay and its parts, constitute the weavingr devices and ull these parts are of usual construction and well-known to those skilled in the art.

The center fork filling detector mechanism of the present invention comprises a. filling fork consisting of a series of fork tines 30 which ure separated from each other substantially the distance of three or four warp threads. These fork tines are adapted to be received in a recess 31 in the rece-way of the lay 32. As is usual with center filling forks, the lower group 33 (Fig. 5) of werp threads constitutes the fork grid with which the forlr tines 30 cooperate. When" the shuttle., in its flight through the Shad 34 leenzgs'Y a". filling behind it, the filling, indicated il.' 35 in Fig. 5, lies o!!A the bottom group it"of warp threads.

at F. If. M. is mounted on a brficket` liz) Thereupon, the fork tines 30, which are raised previous to the passage of the shuttle past the fork tines, descend upon the filling 35, as shown in Fig. 5, thereby preventing the loom'stopping means from beingv set in operation. But when the shuttle' ails to lav a thread in theshed, the vfork tines 30 descend into the recess 31 and the loom sto i ping means are causedto be actuated und t e oom to be stopped.

The fork tines 30 are secured et their forward ends in a hub 36 integral with e shaft 3T pivotally supported at euch end on the pointed ends of twosetserews 38 adjustably received in ears 39 of n bracket 40 secured to the front of the ley and half way between. the selvages. The fork tines 30 are raised just previous to the passage of the shuttle. through the shed by the action of a fork actuating cam or eem member 42 which is pivoted at 43 on a' downward extension of' the bracket 49. The fork actuating com member is T-shaped and the cross-piece or cam part thereof is provided with an active portion or rise 45 which is adnpted to cooperete with e cam finger 46 depending downwardly from the hub 36 and interposed between the cam member and the lay.

The construction of the above-described parts is such that when the eam member 42 swings to the left (viewing Fig. 3), the rise 45 of the cam member engages the eem finger 46 so that the shaft 37 is thereby oseillated to raise the fork tines 30 sufficiently high to permit the shuttle to pass through the shed without touching them. Depending from the forward side oi the hub 36 so :is to engage the cam member 42 on the side opposite to that on which the finger 4G engages it, is a second cum linger 53 which is adapted to be engaged by the fictive part 62 ofthe fork actuating cem 42. lVhen the cani member 42 is muved to the right (viewing: Fig. 3). the active `part 62 of the cam en gages the cam finger und thereby causes the fork tines to descend into filling detect ing position toward the filling. llt will he observed thnt both the 0am ii1igers4fh1nd 55% ure onlyI in contacting enge-gement with the ruin surfaces of the fork actuating; ram 42, :ind that; ronseiuiently. when the cuni member 42 swings to the right und the :ivtire piirt 62 of the cam member has engaged the cum finger .53 tu depress the fork tines. further movement ot' the van: member 4:2 to the llfht has no actuationv inliuenoe on the fork. which *im* completes its filling detecting opel-nl ion solely unfle. the iufiuenc'e ol ,gravity and the momentum imported to ii, by the cam meinber. There is thus Serured :1 ver)T light und delicate (enter vfork I'illingr deierting notion which een hnve no detrimental etert. on the filling. .It is believed flint this the first instance in u'hirh n center lillinp; fork is entirely disconnected from its actuating ToV with n cutaway portion 48 which permits e hook 4910 be formed on the lett-hund end of the cern member. When filling is present, the fork actuating cam 42 swings to the limit of its rightwerd movement (viewin Fig. 3) against a stop 44; but when filling 1s absent, the eem nger 46 of the fork is received in the cutaway portion 48, and thereupon the hook 49 engages the finger 46, which arreists further movement of the cum member; thereupon the loom stopping means are thrown into operation to stop the loom.

The fork actuating cam 42 is moved in ono direction to raise the fork tines und is moved in the opposite direction to permit the fork tines to descend. The means 'for actuating the cam member 42 comprise a lever 50 pivoted at 51 on a bracket 52 secured to the front of the ley. The upper arm 54 of the lever 50 is connected with the eem member 42 by means of a. link 55 provided with erradjustrnent block 56 by which the interrelution between the lever 50 and the cam member l2 may be ad' justed. The lever 50 is rocked to more the fork by a. belt 58 which passes around n ooved puliey 59 integral with the lever. )ne end of the belt is secured to e pin till :idjustehiy mounted on the loom frame :1nd the other sind is ronneeted by e springP 61 with :i stud formed on the brnelret 5:2. TWhen the luy starts to the rear, the belt 5S is pulled around the pulley 59 x1nd the spring 61 is distended to eompensate for the increased distance betweenV the luy and the pin 6Fl to n'liiffh the belt is fastened. 'This turns the {nalley thereby swinging the erin 51 to the loft. viewing Fig. 3. and raising the fork.

The fork should not he raised. however, until the ley has travelled n. sntiicient distnnee to the rear to allow the tinus to rieur the fell. In' order that the fork muy be raised when it Wil! Fleer the fell :1nd that the raising of the fork nanfa he adjusted to occur at the eurliest possible moment after such time. the movement of the pulley on under the influence of the bolt 5S is delayed. The means for restraining); the lnoveuunt of the pulley comprises a emu pluto (iii udjustnbly seein-ed to the loom freine by :i bolt (H und un arm 65 formed integral with the lever :ind pulley :39. Then the luy is on the front renter, shown in Figs. 2 und 3. the urm {'5 lnys ubove the fem plete G3 and as the luiY mures to the rear the lever 5i() is restrnined from movement until the arm hns missed beyond the end of [the 0am pluie. This cnnstruction causes the belt 5Fl to slip over the pulley 59 until the Control of the dem plate groove of the pulley unti ceases. at which time the pulley will be rocked by the belt and the fork raised. The speed with which the fork is actuated may be varied by increasing or decreasing the diameter of the pulle 59. It is apparent that the time of raising' the fork may be varied by adjusting the position of the cani plate (33 so that it shall be raised as soon as it will clear the fell and thus avoid being struck by the shuttle whether the loom be actuated by hand or power. After the lever has been turned until the arm 54 engages a stop lug 66, the belt aain slips in the l t e lay reaches the rear center. A guide block 152 keeps the belt from running out of the groove on the pulley 59. The belt 58 will slip over the pulley 59 at any time that the movement of the fork or the actuating cam 42 is resisted. This provides a frictional actuation of the. parts as distinguished from a positive movement which c an not be stopped without iiijury to the mechanism.

The fork is lowered by the action of the spring 61 in taking up the slack in the belt as soon as the lay starts to the front. After the pulley has been turned sufficiently to cause the arm F14-to engage a stop lug 154, the belt. slips over the pulley as before but in the opposite direction. It is thus seen that the cam member 42 is actuated in alternate directions first to 4raise the fork tines,

and then to depress the fork tines part way` resent the lay on its forward center, that isl to say, atithe limit of its forward movement,

with the reed beating the 'filling against the fell. W'hjznthe fork actuating cam has been moved to ift the fork tines, on the backward beat of the lay, the relation between the fork actuating cam and the fork fingers 46 and 53 is as shown in Fig. 9. The lay n'ow beats u'p again and the fork is kept raised until the active portion 6&2 of the cam engages the cam finger 53, and thereupon as the active portion 62 passes the linger 53, the fork tines aredepressed toward the filling, but before they have reached the filling the active part B2 passes beyond the finger 53 and so the fork tines descend upon the filling under the influence of their own momentum, the fork being at this point. as illustrated in Fig. 8, not actuated in either direction bythe fork actuating cam. Just previous to-the arrival of the barb of the book e9 opposite the fork finger 46, the fork fines have descended to the level ofthe filling. lt now the filling iS resent, the hook 49 will pass ino erativelyl'by the fork finger 4G, es shown in `i 6. ut if the filling is absent. the fork tines will descend into the recess 31 and the fork finger 46 will move into the path of movement of the h'ook 49 (as shown in Fig. 7) and stop the further movement of the. fork actuating cam 42. This will cause the arm 54 of the lever 50 to stop in a substantially vertical position, viewing Fig. 3, midway between the stop lugs 66 and 154, The swinging movementof the lever being arrested,` further move'l'nent of the lay causes the belt 58 to slip over the pulley 59. This catching of the fork finger 46 by the hook 49 on the fork actuating member 42 causes the loom stopping means to be actuated on the same beat-up of the lay.

. The mechanism by which the center filling fork causes an actuation of the stopping vmeans comprises a knock-olf lever actuator 67 which is slidin ly received in a slot in a bracket 68 secure to the breast beam. At its forward end the knock-off lever actuaj tor is provided with a slot 69 which loosely engages a pin 70 projecting laterally from the upper end of an arm 71 which is secured to a. stop shaft 72 journaled within the hol low chan e shaft 13. This arm 71 and sto shaft 72 o not perform in connection, wit 1 the present invention any other than their usua function, and are only appendages of the feeler loom to which the various mechanisms of the present invention are applied. The slot 69 in the forward end of the knockthe knock-oil' lever to actuate theshipper, i

the knock-off lever actuator is provided with a lug 74 which is noiunilly positioned immediately behind the end T5 of the liiiockoff lever se that when the knock-olf lever actuator is moved forward, the lunr T4 is pushed against the end 'I5` of the knockol lever and the latter is actuated to knock ofi` the shipper to stop the loom. Depending from the rerfr end of the knock-oil' lever actuatoi is a finger 77 which is adapted to be struck by a bunter 78' extending forwardly from the front uppei-end of the lever 5G when the fork actuating cam is held fast by the cani finger 46 on filling absence. Thereupon, the forward movement of the lay brings the l titi T8 into engagement with the lower end of the finger T7. and the knock-off lever actuator is moved forward to atop the loom. The knock-off lever actuator in conjunction with the knock-off' lever and the shipper constitutes the loom stopping devices.

The mechanism bf.' which the center forli lling detector mechanism is rendered inoperative or fln'ictionlcss on the first heatup of the lav after the replenishing opera-- tion comprises a catch Sil loosely mounted on a pivot pin 8l projecting laterallyv from the chan e lever 16. This catch is nor- :nelly7 held in the position shown in Fig. 2 by means of a downwardly projecting finger 82 which is adapted to press against` the forward end 83 of the bracket G8. (ln the under side of its forward end. thtl catch S0 is provided with a hook S5 which is adapted to cooperate with a shoulder 8G formed on the upper side of the forward end of the knock-off lever actuator. lVhen the filling feeler mechanism indicates critical or predetermined exhaustion of filling and the change lever is causedto be moved forward. as before described. the hook S5 on the catch SO drops down in front of the shoulder 86 on the knock-ofi' lever actuator. The weft replenishin operation takes place on the beat-up of tne lav succeeding the indiF cation of critical exhaustion otl filling. and during this time the change lever is held in its outward position with the hook Si in front. of the shoulder Sti. As the lay beats hack after the replenishing operation. the change lever 16 moves rearwardly and the hook is thereby brought into engagement with the shoulder 86, and as the change lever continues its rearward movement, the kn0ck-oflf lever actuator is moved rear-- wardly therewith, moving a shoulder 88 formell on the rear under side of the knockoff lever actuator into engagement with a "boss S9 projecting upwardly from the bracket GS, thereby causing the rear end of the knock-off' lever actuatorvto he lifted into the position shown in the dot and dash lines in Fig. Q. The return of the change lever to its normal position returns the catch to its normal position. The lower end of the finger 77 is now above the path of motion of the hunter 78 on the lcvdr 5U. so

that in case the fork lines (lo not engage the p filling on the first pick of the shuttle a 'ay from the replenishing meclianisni. the loom Will not. be stopped. The rearward movements of the change lever and the ltnoeleofi' lever actuator are such that the rear end of the knock-off lever actuator is lifted into its inoperative position before the fork Lines descend into filling engaging position. It is to he borne in mind that` the tingen?? on the rear end of the knock-ofi' lever actuator assumes the' osition shown in the dot and dash lines in 2. before thc lay beats for- Ward. As the lay is completing its 'Forward movement, a plate 90 projecting upwardly,7

and laterally from the upper end of the lever 5G comes into engagement with the finger TT to return the knock-oli' lever actuator to its normal position. The position of the plate 9) is euch that its engagement with ther finger 77 does not cause the lug 74 t0 move into engagement with the end 75 of the ltnoclcofl lever Q6, and so, the* loom is not stopped on this beat-up of the lay. which is the beat-up following replenishment.

The mechanism for rendering the center fork filling detector mechanism inoperative or function less on the first beat-up ofthe lay when the loom has been restarted after stoppage, comprises a lever 93 pivoted on` a pin Jl projecting laterally from a bracket 95 secured to the front of the bracket, on which the knock-off or shipper lever is pivoted. This lever 93 carries on its upper end a crosspiece 96 which extends longitudinally of the loom one end of the cross-piece being bent. rearwardly at 97 to take' against the shipper 25 and the other end 98 of the crosspiece ending in front of a lug 99 depending from the forward end of the knock-ofi' lever at'tuator. torsion spring 101 presses the lever flvi reaiwvardly so that the end 97 of the cross-piece .lf is pressed against the shipper 25 when the loom is in operation. When the loom is stopped for any reason the shipper is moved rearwardly, and thereupon the spring 101 causes the lever 93 and its crosspiece 96 to move rearwardly. the end 97 of the cross-piece following the shipper 25, and the end 9S of the cross-piece moving into engagement with the lug 99 to force the shoulder 88 up over the boss 89. thereby causing the ltnocleo' lever actuator to assume the position shown in dot and dash lines in Fig. 2. The imockmil lever actuator being in this position on the first beataip of the la); on the resumption of the loom operation, the plate 90 will come into contact with the lower end of the finger T7 ofthe knocleotf lever actuator and will restore the latter to its normal position. As Va result of this mode of operation.` loom stoppage will be prevented on thisheat-up of the lay, as before described. even though the operator had previously turned the loom over and thereby moved the filling and the fork tines ont` of engagement with each other.

Throughout the descriptive portion of the foregoing specification the center fork filling detector mechanism has beeii described as .i

up of the lav on the resumption of the loom operation following the stoppage thereof.
