AUTOMATC MULTIPLE-SHUTTLE TEXTILE-LOOM.

Application filed October 16, 1913.

To ZZ ywhom 'it may concern.'

.Be it known that- I, LEVI E. SALISBURY, a citizen ot' the United States, residing at lhovidence, in the county of Providence and State or' Rhode Island, have invented certain new and useful Improvements in Automatic B'l'ultiple-Shuttle Textile-Looms, of which the following is a specification.

The present invention relates to certain novel improvements in automatic looms for weaving textile fabrics, the loom being of the multiple-shuttle type in which continu ously traveling non-reciprocating shuttles are employed. In fact, the improvements Aforming the subject of the invention herelthe pre-shedded sections of warp is successively beaten up'into the fabric by the action of the immediately following respective Sections of the combor reed,

The objects sought 4to be attained by the present improvements are; to simplify and reduce the cost of the loom; to materially lessen its weight; to greatly reduce the area of floor space occupied by the loom; to successively and automatically temporarily re' duce the speed of the propelled shuttles at the weft-charging station without varying the normal speed of the endless actuating or propelling chain; to provide improved means for beating-up the weft, and to produce a shuttle whose capacity for holding a. given length of the infolded weft-thread is equal to a shuttle having a materially greater length, thereby permitting the loom to use a greater number of weaving units, thus increasing the output of fabric without increasing the length of the loom or its rate of speed.

It may be stated that an automatic textile loom embodying the present improvements is capable of producing woven webs of cloth having identically the same appearance and general characteristics of similar goods woven on the usual reciprocating shuttle looms.

In the drawings the improved loo-m is represented as having a series of five weftcarrying shuttles continuously passing in a regular order 0r sequence between the shedded warp-threads, and having the weftthreads trailing from the respective shuttles successively beaten up into the web. As thus arranged, each temporarily working shuttle, together with its coperating harness sections and beating-up means, may be termed a weaving unit. loom may be constructed and arranged so as to use a greater or less number of said weaving units. In my improved loom represented herewith ive picks of weft-threads are successively continuously woven intothe web, while the continuously traveling endless chain is moving a distance substantially equal to the width of the web.

The following is a detailed description of the more essential parts and instrumentalities or devices embodied in my improved automatic multiple-shuttle loom, including the manner of their operation. In view of the fact that the description of the several elements or devices are arranged under corresponding sub-titles, it is thought that ay general description of the loom as a whole mav be unnecessary.

Main frame 0f the ZoOna-The two spaced apart vertical .end members a a of the loom are connected together by the upper and lower horizontal chain-supporting and guiding ties al a2; the front or breast beam n3; a tie-bar a4 supporting the rocking levers which operatev the harness-actuator arms; and a pair of -upperand,lower tie-bars a5 a6 to which the upper and lower harness-guides h2 ha are secured. To each of the outer ends Obviously, the

of the frame members a is fixed a semi-circular extension C1 arranged in a vertical plane, the same constituting a continuation of the chain-track formed in said ties al a?, and alsoforming a supporting guideand path for the continuously traveling shuttles in their passage around the curved outer ends. The said members C1 each encircle a sprocket-wheel B revolu'bly mounted in brackets ng secured to the respective frames n; the said wheelsbeing constructed tosupport the respective ends of the chain.

which may consist of any suitable or wellknown arrangement, is represented as including in its construction a belt-driven loose pulley b1 adapted to be clutched thereto by a member b2, which, through intermediate gearing, etc., rotates a shaft b to which is secured the chainactuating sprocketwheel B-see Figs. 1, 2, and 3. The loom is also provided with the usual warp-beam 10G, takesup roll co5, andv the winding cloth roll co4.

General arrangement of devices-The drawings represent the loom as having the main driving mechanism located at the right and arranged to normally actuate the linkconnected endless chain A in a continuous manner at a uniform rate of Speed. The ychain extends longitudinally along the front portion of the loom in a vertical plane; the upper and lower runs of the chain are substantially horizontal and parallel, the direction of movement of the upper run being from left to right. The chain is constructed and adapted to automatically actuate in the proper sequence practically all of the various devices or instrumentalities employed in the loom for controlling the production of woven textile fabrics. That is to say, the i alternate links sof the chain are each caused to propel a guided shuttle carrying the weftthread 101, and the intermediate links 71, control the movements of the several pairs of. harness-actuatorarms L` L1 and the individually movable dents of the beating-'up comb. The chain A is also employedfor intermittingly operating'the devices for selecting the the adjacent shuttle-supporting guide C are removably sea-ted in the stationary upper bar al and .maintained in position by clips al". See Fig. 4.

Main actuating cha/n.-The endless chain A consists of a plurality of connected uniformly spaced links s alternating with links L, mounted for continuousendwise movement in said frame ties al, a2. Each pair of said links s, 7L, is provided on the upper face with a strip h5 having a wave-like camgroove it therein, the latter being continuous throughout the length of the chain.

The grooved portion causes the individual dents ofthe comb K to successively beat up the weft-threads into the web w3. The chain is provided on its underside with a continuous cam-groove 71.T adapted, in coperation with levers Z, Z2, etc., to effect the shedding of the warp-threads carried by the several harnesses. The cam parts proper of the said grooves are located in the links 71, as stated, whereby the individual dents of the comb are successively moved into and out of normal action to beat u p the portion of weftthread delivered from the immediately preceding shuttle and at the same time to properly position the corresponding sections of harnesses in advance of link Lscarrying thek next succeeding weft-charged shuttle. The straight portions of said grooves, 716, k7, lformed in the links s act simply'as Vguides to keep the beating-upand harness-actuating devices temporarily inactive until operated by the grooves of the following link 7L.

Shuttle construction-'My improved selfcharging shuttles S are mounted on the several links s of the chain A, and slidably sup` ported in the ways or track formed in said parts @,Cl. Each shuttle is provided with main upper and lower flat plates s1, s2 having guide {ian'ges s3 onthe back edge thereof; the upper plate s1 has an open narrow longitudinal slot sa therethrough to freely receive the free ends c2 of the weft-feeder arms c1, later described. To the rear end of the shuttle is mounted a small revoluble wheel S5. in normal frictional engagement with a wheel 1; revolubly mounted in a bracket t fixed to the shuttle link s. The shuttles are normally propelled through the medium of said elementss, t, tl-and s55 To each of the outer longitudinal edges of the shuttle is pivoted at n3 astraight row of uniformly spaced swinging light shuttlearms N; the pivots of .one row alternating with those of the opposite row. The free ends of the arms N carry each a'pair of spaced downwardly extending short pins. n adapted to be temporarily engaged by the weft; theba'se s2. of the shuttle is provided with-fixed upwardly extending spaced pins S10 alternating with one another on each side of the center line and arranged in relation to the said pins n of the respective arms N. Fig. 11 represents the relative position with the weft, and Fig. 14 shows portions of the shuttle while the weft is being drawn from its rear end. The latter figure morev clearly represents the weft as it is normally engaged by and bent around the pins 31 and n. Fig. 11 also represents the opposed stationary cams s", S9 which actuate the shuttlearms N of the traveling shuttles.` In Fig. 14.111 indicates the median lines of the inwardly swung arms N; 'the upper plate .s1 and the major portions of four of the arms, however, (except the corresponding pins n) have been omitted in order to more clearly `two pins n of each arm coperate with a pair of the relatively stationary. alternately arranged pins s1 in folding the thread. Practically each larm takes up (in moving from its normally open or empty condition to its normally charged condition) an amount of thread equal to four times its net length, o r four-fold. Each movable. arm N of the shuttles is also provided with a device adaptedv to prevent it from moving too freely. See Fig. 13. The upper side of the arm has a recess n2 therein, located contiguous to the pivot-pin n3, in which recess is confined a very light spring n4, surmounted by a disk a5 of felt, the latter pressing yieldingly against the underside of the upper iat plate s1 of the shuttle, the arrangement constituting a friction brake-.-

Device for temporarily 'varying the speed of shuttle-'At or near the shuttle-charging point or station, at the upper left endof the loom, thechain-supporting frame C1 is provided with a bracket T1 having 'its upper portion' extending inwardly over the chain; to the bracket is securedl a longitudinal plate T positioned edgewise -in a vertical plane and' provided with an elongated cam-groovel t7. The said bracket or standv t, carrying the wheel t1, isprovided on its back face with 4 an angularly movable, normallyseated arm the lower part of bracket t, while a small v toothed spur gear t3 is fixed to its opposite end, said gear being in continuous mesh with a similar gear t4 adapted to turnona stud fixed in said member t. A flat link or arm t5 is secured to the front face of the last-named gear; and having the free end of said arm t5 provided with a pin t6 normally positioned to enter the open camgroove t7 of said plate T; the groove being so arranged that when the pin t of the normally propelled shuttle enters the groove (SeejFig. 7) the continued normal travel of the bracket twill guide the pin downward in said groove, thereby moving the gears in the arrow-direction and causing the free end of arm t2 to engage the shuttle andvtcmporarily propel 'it ahead at double the normal speed preparatory to charging the shuttle; the position and relation of the parts then being substantially as shown in Figs. 8 and 9. The continued norma-l advance of the' chain causes the pin tGto move upwardly in the cam-groove while the shuttlc-charging operation is being effected; the rate of speed, however, ofthe advancing shuttle, in connection with the temporarily reduced movement` of the upper engaging end of the arm t2, meanwhile being but onehalf that of the speed of the chain, the result being to practically double the length of time in which to charge the shuttle. The normal relation of the several parts will be resumed substantially at the instant the pin t6 passes from the forward end .e of

`the cam; the action just described being successively repeated during the charging of each shuttle.

Weft-selectz'ng and feeding means-E indicates generally the mechanism employed and actuate pivotally mounted levers c .jointed to bars c1 endwise movable horizontally in the head of a Xed bracket c3- see Fig. 15, &c. The inner ends of the members c1 are each provided with an eye c2 through which' the weft-thread w1 passes fromthe respective spools Q02. The said eyes c2 are adapted each to carrya dili'erent thread and to be automatically positioned singly in the path of the channel sf of the respective shuttles and somewhat in advance of the latter, in accordance with the prearranged order of the threads. The feeders, assisted by springs c, are retracted to the normal osition immediately after the shuttle -has passed. s

Wcft beating-up demper-This device K is shown most clearly in Figs. 17-18. To the back of the horizontal plate a9, fixed to the front of the said tie-bar al, is secure'd a member k3 extendinglongitudinally across theloom and provided with spaced thin ears is, in which ears a rod 7c is supported. A

lseries of individual 'dents 701, alternating with said ears, forming a comb, areipovably mounted on the rod and having the lower portion Zon of each dent in engagement with the groove Z1. of the continuous camplates 11.5 secured to the upper face of chain A. The arrangement being such that the vmamut-'Flic drawings represent twentyfour laterally spaced independent heddlecarrying harnesses H, divided longitudinally into fourteen sections H1, each harness portion fixed to a thin blade h1 mounted to reciprocate in spaced slots 71,4 formed in the stationary upper and lower horizontal guide plates la?, h3. See Figs. 1 and 4. As hereinbefore stated, the harnesses of each section or group are reciprocated vertically by means of a pair of connected rock-levers Z, Z2, pivoted to the horizontal tie or bar aff The' upper end of lever Z is in continuous operative engagement with the cam-groove k7 formed'inthe lower face of the links of ,chain A; the' lever Z2 being jointed at its lower end to a strap-link 2, in turn jointed to upper and lower links z', t1, fulcrumed respectively to the heads y', jl, to'which are secured the respective horizontally extending upper and lower harness-actuator arms L, L1. rlhe said members j, jl are fulcrumed at j2 to a partition of the casting a2. As thus constructed, the movements of the rock levers Z, Z2, are caused to positively open and close the arms. L, L1 through the medium of what may be termed a toggle-jointed connection.

Indicators, eta- The means .employed for positively and progressively indicating and effecting the action of the harness sections -are substantially as follows: The prear ranged step-by-step moving harness-pattern-chain X, having, say a series of twenty- `four sections-one section for each harness-is disposed 'transversely of the loom, the sections being provided with the wellsired. The several harnesses, twenty-four being represented, are divided longitudinally of the loom into fourteen sections or groups, each group being actuated by a pair of the said arms.L, L1, whose opening and closing movements are controlled by the said 'cam-groove h? of the main chain A, operating through said intermediate connections. F igs.` 19 to 25, inclusive, show the construction and arrangement ofmeans for automatically detachably connecting said arms to a section of harness. Fig. 19 represents a member of the initial section of. harness having its blade-k1 carrying the front indicator Z1 engaged by a pre-arranged riser-roll x1 of the pattern-chain X; the indicator is horizontally slidable and having its opposite end cl2 engaging the lower part of a small rock-arm e centrally pivoted to the blade; the latter has an upper arc-shaped opening therein through which a lug e2- of the rock-arm extends, the lug being engaged by the rear end dgtsee dotted lines) of the back indicator. The upper and lower end portions e1 of the arm e are engageable, respectively, with lugs f2 of hooks f, f1 pivoted to the blade 701; the latter being provided with independent vertically arranged'upper and lower alining narrow central slotted openings 72,8, 7t1, through which the said arms L, L1 extend. The proximate edges of the arms bear against the central ties 71,10 separating the slots 71,8, 71.1. In Fig. 19 the arms are 1ndicated Sectio-nallyA in the closed position, all the harnesses of that section -then being level in the midposition.\ As thus constructed and arranged, 'the indicators mounted on the front side-of the blades 71.1 of the several sections of the harnesses are, caused to lockthe upper Ahooks 'f to the upper edge ofthe arm L and the indicators on the opposite side of the blades operate sidevof the blade.

the extreme lower' end of its stroke.

in arsim1lar way to actuate the lower hooks f1 to lock the latter to the lower edge of the` arm L1. The'drawings represent the movable indicators d1 located on the central line Q; this line designatesthe neutral or level mid-position of the harnesses' See g, Fig.

l. At the right edge of and projecting from the blades are fixed vertically spaced upper and lower dogs o r cams d?, d4, disposed wlth -respect to the line Q, cam al1 being on` the front side below the center line and cam d3 being above the line and on the .opposite As thus constructed and arranged, the short lengths of the several harnesses of the Vnext advance section or group are caused to be engaged and 'positioned by the'centrally located sub-indicators d slidably mounted in the correspond-` ing transverse bar D fixed to members d5 secured to the frame ties a5. That is to say, the blade when locked to the upper arm L positions the lower dog d4. on the line Q' when it (the arm) is in the extreme upper position. Conversely, the movements of the lower fellow arm member L1, when locked to the blade, positions the upper dog 073 on the line Q when the 'last-named armv isSin ee also Figs. 2li-25. Obviously, when the upper arm is locked to the blade of the harness,` the lower arm is in the unlocked condition, and vice versa. Thus, it is evident that the front indicators d1 o-f the movable vertically guided harness-blades 72.1, in coperation with said members d, e, e1 and f2, operate to swing the upper Alatches or hooks f and lock them to the upper arm L, the lower arm 1L1 then being unlocked from its hooks f1. The indicators on the backl of the blades operate in a similar manner to lock the hooks f1 to the `lower arm L1, larm L then being unhooked; the action taking place when the arms are fully closed relatively to the mid-position or center line Q.

`The operations above described successively` follow one another in a progressive orderdf, upon arriving at the center line Q, ac-

cording as the harness is moving down-or up, .are caused to engage the respect1ve subindicators (Z, thereby moving the-latter endwise4 to set o-r position them in advance, so l as to be engaged by the corresponding indicators [Z1 of the next succeeding harness section. 1

Means for actuating the weft-selecting and harnesac'hangz'ngdeoces L", X. (See Figs. l, 2, and 15.)-To the upper left end of the loom is slidably mounted a transverse barp having its rear end in continuous en gagement with the said cam-groove 71.7 of the traveling chain A; the front end of the member p being adapted to engage the teeth of a ratchet-wheelgv1 xed to a suitably mounted shaft p3 (Fig. 15), to which sprocket-wheels w3 carrying the patternchain of the said weft-selecting device E are secured. A pair of angle gears p4, actuated by the movements of shaft p3, together with intermediate mechanism, are caused to actuate the harness pattern-chain X in a step-by-step manner. See also Fig. l. I make no claim, however, to means for effecting the movements of the weft-selecting and harness-changing devices.y

Weft stop-motion dem'ce.--At the right end of the `loom is pivoted a normally sta- .tionary short vertical stop'lever b5 having its lower end disposed immediately over the shuttles; the said lever, whenbrought into action, is adapted to trip a suitably. mounted rod b4 connected in turn to a clutch member, as 722, An arc-shaped slot .97 is formed :in the upper plate vs1 of each shuttle near the pilot end `s1, throughwhich slot extends a pin s6 fixed tothe foremost swinging shuttle-arm N. YSee Figs. 9 and 1l. -In the normal operation of the shuttles the latter suc`` cessively emerge empty'from the warps, thus indicating that the weft has been properly delivered` from the shuttles during `their transit across-the loom, the'several arms N then being open, corresponding with the una folded position, thereby, too, swinging the v pin .s6 ofthe forward arm rearwardly in its slot so as to 'escape the saidstop lever. If, however, the shuttle has failed to deliver all or a portion of its' pick, or even not to have been chargedat all, the said pin s6 of the forward' nfold'ed arm will engage and actuate the stop-lever to release the clutch and stop the loom. The loom is adapted to be started and stopped through the medium of a manually operable lever b3, also connected torod bt. y

1 Means for actuating the tacaup roll.- The cloth take-up roll/L05, indicated in Figs. 1, 2, and 3, is adapted to be actuated in an intermittent manner by means locatedl at the upper right'end of the loom. Said means consisting of a horizontal, slidably mounted transverse bar a having its rear e'nd adapted to engage and be actuated by the cam groove la? ofthe moving chain A; the front end of the bar has a pawl engaging a ratchet-wheel 'al xed to a vertical shaft u2, the latter having a worm ai at its lower end engaging a wheel a4 secured to the shaft or trunnions of the take-up cloth roll in a well-known way. The upper end of shaft u2 is arranged to'receive a handle, thereby adapting the d evice to be manually actuated when deslred.
