Specification of Reissued Letterslatent. NOV. 23, 1920.

Original No.'1,221,410, dated April 3, 1917, Serial No. 761,689, filed April 1'7, 1913. Application forreissue filed October 12, 1920.

To all whom it may concern:

Be it known that 1, WILLIAM L. BARRELL,

a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Weft-Replemshmg Looms, of which the following is a specification.

The present invention relates to weft-replenishing looms of the same general character as that which forms the subject-matter of my copending application Serial No. 737,967, filed December 21, 1912.

The purpose. of the present invention is to provide more efficient and smoother working mechanism than that shown in the afore said application.

Of the accompanying drawings, which illustrate a loom embodying the present invention,

, Figure 1 represents a left-end elevation, the shuttle-box parts being shown in section and some parts being otherwise broken away for the sake of illustration.

Fig. 2 represents mechanism, partly in elevation and partly in section, for exchanging shuttles and for loading the shuttles with full bobbins. The viewpoint of this figure is the same as that in Fig. 1. i

Fig. 3 represents'a vertical section, on a larger scale, of the left end of the lay and the adjacent parts, including a shuttle 1n operative position in the shuttle box.

Fig. 4; represents a section similar to Flg. 3, showing the parts in different positions, the shuttle being ejected from the shuttle box and restingupon a receiver.

Fig. 5 represents an elevation of a movable member by which the loading mechanism is operated to place a full bobbin in a shuttle.

Fig. 6 represents an elevation of a device for supporting in operative position the .op-

crating member shown by Fig. 5.

Fig. 7 represents a rear elevation of the device shown in Fig. 6, the same being attached to the frameof the loom. i

Fig. 8 represents a front elevation including the upper left-hand portion of the loom frame, a portion of the bobbm magazine mounted thereon, and a carrier which carries the empty shuttle to the magazine for loading and fromthe magazine to the lay for use in the loom-f Serial No. 416,554.

Fig. 9 represents a top plan view of a fixed support which holds a shuttle duringv the loading operation, in this figure the front of the support being at the top of the lower halfof the bobbin magazine and the shuttle-supporting means.-

Fig. 15 is a frontel'evation of theielements included in Fig. 14. i

Fig. 16 is an end'elevation, .on a larger scale, of'the parts shown by Fig. 14.

Fig. 17 is an end elevation of the same parts in a different position. v

The same reference characters indicate the same parts wherever they occur. The construction. and operation of the loom in the present instance are similar to those of the well-known weft-replenishing loom made by the Stafford Company of Readville, Massachusetts. This loom comprises the usual weaving mechanism and shuttle-exchanging mechanism, each of which has a driving clutch. These clutches are controlled in such manner that the shuttlerexohanging mechanism remains idle so long as the weaving mechanism is operating,

and the weaving mechanism remains idle while the shuttle exchanging mechanism is operating. 'The clutches are controlled by suitable well-known devices, which cause stopping of the weaving mechanism whenever it is necessary to replenish the weft, the shuttle-exchanging mechanism at that time being automatically started, and when the latter has completeda cycle of Opera tions it is automaticallythrown out of operation and the weaving mechanism is again started. V r

'Two shuttles are used alternately and are taken from the lay for loading. There is a bobbin magazine fromqwhich .a full bobbin is taken to load-each shuttle while it is out of the lay. When one shuttle is in the lay the otherv shuttle is in loading position out of the lay. When it isnecessary to replenish the weft, the weaving mechanism is auto-- matically stopped and the wholly or par-; tially spent shuttle is taken out of the lay and a loaded shuttle is carried fromloading position to the lay. The means which transfers the loadedshuttle to the lay carries the spent shuttle to loading position. The weaving mechanism is then automatically started, and the shuttle-exchanging mechanism becomes idle. One difference between the present invention-and that set forth in my copending application is that in the present instance the loading operation occurs while the weaving mechanism is operating, but in my copending applicationthe loading occurs while the weaving mechanism is at rest. Another difference is that in the present instance the shuttle is supported by a fixed support While being loaded, but in my copending application the shuttle rests upon the shuttle-carrier while being loaded. The fixed support in-the present instance relieves the shuttle-carrier of undue strain and renders the loading positive. Other details of my present invention are hereinafter described and are illustrated bythe accompanying drawings. I I l The upright frame member at the left end ofthe loom is indicated at 10,.the front of the 100m being at the right of Figs. 1 and 2.

The lay 11 is mounted, as usual, upon swords (notLs'hown) and oscillates about the axis of a shaft 12. It is oscillated as usual by a crankshaft *13 with which it is connected by links such as indicated at 14. The bobbin magazine is indicated as awhole at 15. The structure andoperation of this magazine are well known, and it will not be necessary to describe all details of the same. It will be sufiicient to state at this time that the magazineis rotated step bystep about a central spindle 16, and that the bobbins are arranged in a circular series so that they are brought successively into the position from which they aretransferred into a shuttle in loading position. Fig. 1 shows a shuttle w in operativeposition in the lay, and a similar shuttle in loading'position under the magazine.- J v I U The shuttle which is in loading position .is supported by a stationary holder 17, the same being aflixed'to the frame of 'the loom. The details of this holderare shown byFigs.

8, 9 and 10. Itcomprise's two separated supporting portions 18, afront'walll 9, and end

walls

20, 20, the latter having converging surfaces 21 to facilitate the entrance of the shuttle and to position the latter endwise with relation to the loading mechanism.

' he shuttle is locked in the holder 17 by fingers 22 hereinafter described. The space between the supporting portions 18 is to enable the empty bobbin to drop to the floor or into a suitable receptacle when forced out through the bottom of the shuttle. The shuttles are of well-known construction and are generally used in conjunction with a magazine such as that illustrated, the construction of the shuttle permitting a full bobbin to enter at the top and force the empty bobbin out through the bottom, the

interior of'the shuttle being provided with suitable devices for holding the bobbin.

Referring to Figs. 3 and 4,-the shuttle on the lay is held in position during the beating-up operation bya movable shuttlebox front 23 and a binder 24; The movable member 23 is adapted to be lifted to the position shown by Fig. 4, to permit ejectlon of the shuttle from the lay. VVhen the shuttle is ejected it passes into a receiver 25 whose shuttle-supporting surface is substantially flush with the shuttlesupporting surface of the lay. This receiver has stops 26 for engaging the front of'the shuttle to prevent the shuttle from moving forward too far when ejected from .the lay. The

recelver also has clips 27for engaging the ends'of the shuttle to maintain the desired longitudinal position of the shuttle. The receiver isafiixed to the upper end of a bar 28' whose lower end is .pivotally connected to a lever 29, the connection being indicated at- 30. The leverv 29 is mounted upon a fulcrum 31, and is. provided with a cam roll 32 which-rests upon a cam 33.. The cam lifts the receiver from the position shown by Fig. 3 to lift the ejected shuttle to the position indicated by'dotted lines in Fig. 4. The

purpose in so lifting the'shuttle is to enable the shuttle carrier, hereinafter described, to

' pass under with a loaded shuttle and to enable the ejected shuttle todescend upon the carrierso that it may be carried away by the carrier. The bar 28 is provided with-a guiding slot 34 which is occupied by a pin 35- in abracket 36 secured to the lay. When the lay is operating the shuttle-receiver 25 swings with it, the relationof the pivot 30 and rockshaft 12 being such that the arcs of movement of the lay and sliuttle receiver will so nearly coincide that the lay and receiver will not have any appreciable movement relatively to each other.

The cam 33 is aflixed toa shaft 37 which is drivenby a suitable clutch (not shown) only when the weaving mechanism is at rest. When the weaving mechanism, is stopped for replenishing the weft, the clutch for the shaft 37 is automatically connected and causes the-shaft to describe one revolution. During this single revolution the necessary exchange of. shuttles is made, and thenthe clutch for-the shaft is automatically disconnected-and the clutch for the weaving mechanism is automatically connected, all in the well-known manner. The

shaft 37 is provided with other cams which operate devices hereinafter described.

The movable'shuttle-box front 23 is carried by arms 38 which oscillate upon a fulcrum 39. This fulcrum is mounted insultby a spring 47. hen the cam 46 depresses the lever 44 the shuttle-box front is lifted to the position shown by Fig. 4, and while it is being lifted an ejector 48 is moved to push the shuttle from the lay to the receiver 25. This ejector is mounted in a'suitable guide 49 carried by the lay and is operated by the rod 42 which lifts the shuttle-box front. The rod 42 is provided with a collar 50 which engages one arm of a bell crank lever 51. This lever is mounted upon a fulcrum 52 carried by one .of the'brackets affixed to the lay. The lever 51 actuat-es a lever 53, the two levers being connected by suitable :pinand-slot connection indicated at 54. The lever 53 is mounted upon a fulcrum 55, and its free end engages the ejector 48. For this purpose the ejector is provided with a suitable hole through which the-end of the lever 51 extends. The

levers

51 and 53 are so proportioned that a relatively short movement of the lever 51 will cause a relatively long movement of the ejector. lVhen the parts are in their initial position ,as shown by Figs. 1 and 3, the collar 50 1s separated from the lever 51 in order to enable the shuttle-box front 23 to rise" above the top of the shuttle before the ejector pushes the shuttle forward. A spring 56 connectedto the lever 51 retracts the ejector when the shuttle-box front is lowered. The cam 46 is so formed that it permits the rod 42 to rise part WEIY'lJB-fOlG the loaded shuttle is placed in the lay. This movement of the rod 42 enables the ejector to return to its initial position, but it still holds the shuttle-box front 23 at a sufiicient distance above the lay to enable the approaching loaded shuttle topass under the shuttle-box front to operative position;

The shuttlecarrier is shown by Figs. 1, 2, Sand 11. This carrier comprises a lever 57 at the upper'end of which are the shuttleengaging-members. The lower end of the lever is mounted upon a fulcrum 58 which is directly above but nearthe rockshaft 12.

The lever is provided with a cam roll '59 which engages a cam 60 on the shaft 37. A spring 61 moves the carrier toward the lay,

and the cam moves the lever away a from the lay.

Referring :to Fig. 11, the carrier has shuttle-supporting surfaces 62 for carrying an'ejected'rshuttle from the receiver 25 to the stationary support 17 The carrier also has supporting fingers 63 for carrying a loaded shuttle fromthe support 17 to the lay. The ejectedlshuttleis deposited upon the "surfaces 62 by the receiver 25. In order to hold the shuttle in the desired position upon the surfaces 62 the carrier is rovided with abutments 64 which engage t e front side of the shuttle and with movable' fingers 65 which engage the rear side of the shuttle. The fingers .65 are aflixed toa rockshaft'66 and are normally heldin operative position by a -spring'67 coiled aboutthe shaft. As

shown by Figs. 8 and 10, the stationary shuttle support 17 is cut away at 64', -64 to provide clearancefor the elements ;64 -and 65. When'the carrier moves forward to. carry a shuttle to the support 17 the shuttle strikes against the front wall 19 of the stationary support, and the carrier continues to move forwardto the position shown by Figs. 1 and 2. The movable fingers 65 :are

thus caused to swing downwardly because of their engagement with theshuttle, and

when their free ends have passed the shuttle they are returned to their normal position by the spring 67. Upon the'next movement of the carrier toward'the lay, the abutments 65engage the front-side of the shuttle and push the shuttle toward the lay. The shut-' tle slides along the fingers 22 to the'supporting fingers 63 of the carrier and is thereby carried to the lay, the fingers 63 overlapping the lay when the carrier has moved as far as it will go toward the lay. "While the carrier is in the position lastdescribed, the 46 permits the movable shuttle-box front 23 to descend to its initial'position, thereby depressing the weft-end in the throat of the shuttle and confining the loaded shuttle in-operative'position .upon-the'lay; and

when th-e carrier moves forwardythe fingers 63 are withdrawn from under the shuttle and the shuttle then rests upon the lay.

fVVhile the carrier is carrying .a loaded shuttle toward the lay, the receiver 251support's the e ected shuttle above the carrier. Then while the carrier is against the lay the cam permits the receiver to descend to deposit theejected shuttle upon the surfaces 62 of the carrier. The receiver descends below its initial position in order that its upper edge may pass below the bot- I hash-at le-supporting surfaces 18 which support the shuttle for loading .areinclined V and have pin-and-slot connection with levers so'that the shuttle'norlnally tends to slide toward and engage the front wall 19." As an "additional safeguard 'forilocking the shuttle in position. or loading I havezproi vided the devices 22.- (.See Figs. 14 to l7.).

The devics 22 are mounted uponpivots- 68 One end'of the spring engages the lever,

i the holder 17 before engagin the devices 22 being ,at that time below the I lifts the lever 71 to the'pos'ition shown by and the other end is anchored to acollar .98 which is aflixed'to the rocksh'aft. The lever 71', however, acts ositively on a collar 99 whichis likewise a xed to the rockshaft, ,the members 71- and 99 having cooperative shoulders, shown by Fig. 9, which enable the leverL71 to act'positively to move the locking devices 22 from operative position to-the position shownby Fig. 1 The weightof the' lever 71, due to its angular position, issuflicient for moving the devices 22 from shuttle-engaging position. When the s'huttle carrier is moving forward withanempty shuttle, it deposits the shuttle in the lever 71,

ath. of the shuttle, as'shown by Fig. 17. The shuttle-carrier thereafter engages and Figs. 14 and 16,'thereby moving the devices 22 to'shuttle-engaging osition.v The shuttle carrier'and the lever 1 are shown in co-v operative engagement by Figs. 1 and 8. The shuttle holder 17-,as shown by Figs. 14 to 17 is in a horizontal position, although'its correct position is-inc'lined, as 1 shown by- Figs ing; the holder in horizontal position 1n- 1 and 2.;The only reason for show- Figs'. 14 to 17 is to expedite the drawings. I v

I have provided a device for automati-'- cally threading the shuttle as often as a full bobbin is placed thereinj Thebobbin magazine, as is well known, is provided with a weft-end holder, the same being indicated in Fig. 14 at'100. Themagazine is also provided with a wheel 101 overwhose-rim the weft ends 102 are drawn [from the bobbins and wrapped aroundthe weft-end holder." The weft-end holder and thewheel are -intentionally omittedfrom Fig. 1. The wheel 101 rotates in .unison, with the bobbin-em gaging'partsxof the magazine. It: is providedwithnotches.103Iin its rim, for the reception of the weft ends. When the weft ends are wrapped around the holder 100,: the thread is. drawntaut, and there is a considerable free stretch: ofthread from the bobbin-engaging portion of the .magazin,e'

gs.8, 9 and 15.).

to the wheel 101, as shown by Fig. 15. As. the bobbins are successively brought into position for loading, their weft ends engage a hook 104, and sliding along the under edge ofsaid hook finally lodge in the barb thereof, as shown by Fig. 16. This hook remains in the position shown by Fig. 16 until the shuttle-carrier moves to transfer the loaded shuttle to the weaving mechanism; but before the shuttle is taken out of the holder 17, the hook 104 is depressed andthe weft end is thereby pressed downwardly upon the up-- per side of the shuttle adjacent the throat 1.05, (Fig. '13). This throat is of theusual and well-known formation in shuttles of this type, and permits threading by drawing the weft end laterally therein. Thehook continues to hold the weft end while the shuttle is being transferred to the weaving mechanism, and'the weft end is therebycaused to passlate'rally into the throat 105, whereby the shuttle becomes threaded while passing to the weaving mechanism, in consequence of the position in which the weft end is held. The shuttle, in passing to the shuttle box, carries the weft end under the shuttle-box front 23, which upon being lowered holds the weft end against the bottom of the throat 105. The shuttle-box front thus acts 1 upon the weft end to maintainthe latter in its threaded position in the throat.

The hook 104 is mounted upon a pivot 106 I As the magacrum-is indicated am in Fig. 2. The

loader has an arm 75 which is actuated by a lever 76. The arm 75 and lever 76 are connected by a suitable pin-and-slot connection 77 The loader is normally elevated bya spring 78, and it receives its loading movement from the lever 76. The lever is mountcd upon a fulcrum 78 which extends from the frame member 10. A finger 80 (see Fig. 5.). is pivotally connected to the lever 76 by pin-179. This finger is used to transmit movement from the'lay to the lever 7 6 to actuate the" loader" 74. For this purposethe lay is provided with a member 81 which is adaptedto engage the free end of the finger 80. The latter is initially out of register; with the member 81, and is placed in operative position by a cam .82 on the shaft 37.

This cam engages a lever 83 whose fulcrum is indicated at 84. The free endof' the lever 83 is pivotally connected with a rod 85 whose movement is guided by a bearing 86. The upper end of the rod is adapted to engage the finger 80, and except as hereinafter specified the finger 80 rests upon the rod 85.

a portion of the bracket 90, asshown by Fig. 6, a spring 91 being connected to the latch for holding it in this position. The

pin 88, as shown by Fig. 6, is restingupon the upper. end of the latch as if the finger 80 were being supported in;position to be engaged by the .member I 81.

The normal position of the pin is shown by dotted lines in Fi ,6. When the free end of the finger lifted, the pin 88 strikes the inclined surface 92 of the latch'and deflects the latch to the position indicated by dotted lines. The pin 88 is lifted above the upper end of the latch and "the latch is then returned to its normal position by the spring 91. The lifting cam 82 then permits the rod 85 to'de- .scend to its lowest position, but the finger 80 descends only so far as to place the pin 88 upon the upper end of the latch. .The loading mechanism is thus placed in readiness for operation, but it is not operated until the shuttle-exchanging mechanism has completed its cycle ofoperations and the weaving mechanism is started. Upon the first forward movement of the lay the member 81 strikes the finger 80 and moves the lever 76 to-operate the loader 74. The finger 80 is thus moved longitudinally, and the pin 88 leaves the latch 87. When the lay moves to the rear the finger 80 may drop until it .rests upon the upper end of. the rod 85. where it remans until it is again lifted by the cam 82; l v

The step-by-step rotation of the magazine is caused by the return movement of the loader, all in the well-knownmanner. The starting of the weaving mechanism is also caused in the well-known manner. For this purpose the loom is provided with a rock- :shaft 93 which extends transversely of the loom, at the front. This rocksha-ft .is connected by mechanism (not shown) with: the

driving clutches. As shown by F ig.v 1, a rock-arm 94 is-mounted upon the rockshaft and "is pivotally connected to a rod 95. A

' collar 96 is afiixed upon the rod in position to be engaged by lever 97. This lever is mountedupon the fulcrum3l and is actuated by, a suitable cam (not shown) on cam shaft 37. The .lastoperation in the cycle of the cam shaft is moving the lever 97 to connect the. power for driving the weaving mechanism and to disconnect the power for driving the cam shaft.
