known as square mesh fencing. vThe' machine is of'that class 'disclosed in partent N ,745,801, issued DecemberV l, 1.903, to John FV. Dwiggina but involves a substantially different organization constituting a greatly improved construction.

The Dwiggins machine embodies means for intermittently feeding a series of parallel line wires, and mea-ns for carrying stay wires across the line wires in-the manner'of a woof shuttle, the stay wire being looped and the loop wrapped around each line wire Yas the several line wires are reachedv Ain succession during the'feeding of-the stays across the series thereof. The looping andwrapping or twisting devices are voperated successively in one vdirection by a reciprocatory carriage as the latter moves across the-inachine to convey or feed the stay wire, and

are then successively operated inthe reverse direction as the carriage returns to its normal positionV and incidentally feeds another stay wire'across, the series of line wires. In the Dwiggins machine, therefore, the application Vof a stay is'effected by twisting the stay wire around the` line wires one at a time. ln addition 'to theV time consumed by these successive twisting operations, further time is also required for'tlie feeding of the stay between two line wires after each twisting operation. Thus, the time consumed in applying al stay is equa-l to the time consumed by a single twisting operation multiplied by the number of twists required plus the time consumed in feedingl a stayacross the series of line wires.

Thev primary object of my invention is to greatly increase the capacity of the machine byfrediicingthetinie requiredfor the application of each'stay. ln pursuance of this primary object, further ,objects are: n

l. vTo provide for the feeding ofthe stay wire across the series of line wires while the stay previously fed isl being connected to` the line wires.

2. VTo provide for the simultaneous twistingy of' the stay wire aroundal plurality of line wires. i 1 Y.

y3. To secure positive andv prompt kaction ofthe various mechanisms by minimizing the number of reciprocating or intermittently operating parts.. i i

Subordinate objects are to -improve the stay wire feeding and cutting mechanisms; to provide novelmechanism for moving Vthe stay laterally to the line lwires after it is fed across-the same.; anelito simplify and render .more effective `the Vstay wire twisting or Vwrapping mechanism andthe operating connections there'off f To the n accomplishment y of l the objects stated, K and various otherswhichwill 'presently appear,.th`e preferred embodiment of the invention resides in that `construction ,and arrangement ofiparts. tov be hereiiiaiter described, illustrated "in the accompanyingdrawings, and succinctly' defined inthe appended claims. i 'Y In said drawings-y y Figure 1 is a front elevation of the loom.

T hey mechanism 'for rotating the -twisters 7V constitutes one of the primaryfeatures of the present invention, the distinguishing characteristic of this mechanism residingin Ythe provision of means broadly, whereby the twisters, instead of being operated i-n succession from one end ofltheseries to the other, a

will be operated in'series theoperation of correspondingtwisters of different series being simultaneous,-and successive twisters of each,v series being brcughtfinto action: suocessiveiy, twister of a series to complete its operation before theoperation of the-next' twister ,is

inaugurated, Thus, whilethe correspond V ingtwisters of differentrserieswvill be the only onesoperatingin complete coincidence,

several or all of the-twisters of both series may be-operating at-the Sametime, since the last twisters of said series ,may Y comeA in tov action before the first twistersthereof have '27, and having a pair of arcuate slots 30 arranged to receive b'oltsiextending laterally from a disk 31 lreyed tothe shaft 26, -see Figs'. .1, 4 and :13. The .slots provide for'the' adjustment ofthe geen-the latter after its adjustment being rigidly secured to the shaft y its attachment to the disk 31 keyed upon the. latter. Each ofthe gears 27 is arranged to mesh.- with one of the twisterpinions 1.6 during :a `given period of a rotationY of the shaft 26 and Aduringthe remaining period of such movement, vthe twister Toperated bysaid pinion is held against rotationrby the engagement oflthe locking flange 29 'with a fiat locking face 32 formed fon the hub of the adj acentfpinion 16. :v

lt will be noted, by reference to Fig. 1, that the twister'drivi'ng gears 2? are arranged in two' series,'the four gears at the "right facing toward the right side of the machine and the vfour gears at'the left facing toward'the left side of the machine. Thus the two series of gears may be said to be oppos'itely disposed Aand obviously operate .Y the two corresponding series of twister pinions 16 in opposite-directions, so that the four twists-rs at'the right hand side of the machine will rotate in Yone directionand the four twistersV at the opposite endof the ma# chine will rotate in'y the opposite direction.

without, however, Aallowing Teach `lt will also appear,byreferencev'to Fig. 1,

that the. several gears of each series are graduated as to theirmoments-orperiods of operation, the gearat the inner end of the series having the'inost advanced `position and therefore coming intof-action irst,`and` the gear atthe outerend fof' the series being the least advanced andv coming into action last. By `reason ofthis arrangement, the.

several gears of a given series will come successively into coperative relationfwiththe .adjacent pinions so that the operation ofr the twisters of either series will be inV augurated one'a'ter another to yenableveach` twister to producefsuliicient slack -in the stays-wire for the performance of its func-2 ofthe series may be operating at the same time,their periods of operation-will-` not be tion; before the next twister begins to op crate. Therefore,A while i the several twisters coincident.` Theftwo; seriesjofilvgears Vare identical, however, vexcept. for their' opposite d-ispo'sition.This vresults* in the coincident operation of corresponding memberslof the f a' respective series. Y Thus, theinner end mem# bers of the two series offgears orthe :twov Y middlemembers of the entireconiple-ment of gears coincide, while tliejf corresponding gears to the right and leitlrespectivelof; these middle gears, are in jsimilar coincif dence, and'so on, throughout the two series.

Thus, while `the gears ofygeachseries come into action inj succession, ,corresponding gears vof the respective series-are4 brought into action simultaneously. fTherefore,ac-y

iiojo cordingly as the'arrangement is'viewed', it'y may be said toinc'ludefa series of Vtwiste'rsV brought into action successively, j orf two series of 'twister-s. having coincident operation, or a seriesy of pairs fofA twisters,' the dence and the kseveral .pairsxcoming Ainto action iii succession. Furthermore, theenf, tire complement of twisters vconstitutes 'ag series,'.the members of wh.1 ch, located atop-.1.

105 i twisters of each pair operating in coin'ci-` iio posite sidesof' an intermediate point-areV brought into action successively toward theMV 'outer ends of the series from 'such point,-

attention being drawn to these rvarious-- aspects in whichy the structure may fb'e.; viewed inl order that the .claims directed to these Various aspectsof the invention may be clearlyrdistinguished,and fully compre',-

hended. n

During the rotary 'movement of theV twisa -f ters, their looping'and'wrap'ping pins 24, Y, see Fig. 14, alewithdrawn from their.' normal positionszand subsequently restored to* such position; i To effect the performance Y of this function at the proper time, aseries of cam levers, see (Figs. 4 and14, are fulcrume'd at the rear edge'of the twister table 4 withl their bifurcated"'frontendsi ene-1 Vvgaging peripheral groovesin the .collars 23'. The rear ends of the levers 33 'carry-7.130,

rollers `36 .disposed-in coperative relation Y withtwo graduated-series of cams 37 adustablymounted Aon disks 88 keyed or otherwise -secured'toa cam=shaft38 journaled at vits oppositeends in the yside frames 2 and 3 of Vthe machine.: TheY graduation of the cams 37 correspond with the Ygraduation of the Vgears 27 ,"forthefreason'that the period of operation of eachpin 24-with' respect-to the period of rotation'of itstwister head is the same, and therefore each cam 37 must have the'same relation to the-corresponding gear27. y y f At a predetermined pointV in' the vrotary movement of the twister, its pin is drawn down against the resistance of the spring by the oscillationof the lever 38' and the consequent depressionof the collar 23 as acam 87. contacts with and elevates the roller 36 carriedby-the lever. While. the*v cam is riding underthe roller, the pin remains de pressed,but is immediately' elevated by the n spring25 as soon asth'e has passed beyond the'roller.V Normally, the pins .24 are located at the front sides Eofthe twisters, as shown in Figs. 4 and 8.

Ass0ciated`with each twister and normally y located `/abovethe same is a presserfoot 39 comprising 'a hub 40 partially surrounded by an-Yarcuate flange 41 disposed concentric with the"hub,.see Fig. 15, the hub and flange being connected by a top wall 42 and the foot as a whole being formed at the outer' end of Y :soVV

a shank43 provided on its under side with of the foot, and from the loweredge ofV this abutment the bott0m..wall ofthe hubvis gradually inclined upwardly to form a loop 4depressing cam 47 substantially coinciding with which is a second loop depressing flange 48 produced by inclining a lpotion'of the kunder face of the flange 41 insubstantial colncidence with the inclination of the cam" 47. 'The several shanks 43 of the presser `feet are `connected by what may be termed the presser foot bar 49 disposed lengthwise of the twister'table 4 at the rear edge there-V of, see Fig.` 8. The slides 44` of saidshanks tween guides 50 secured to the table, see Figs. 8 and 9. r[he presser feet normally'occupy the positions shown in Figs. 4 and 5, and assist, as will presently appear, in the Wrapping of the stay around the line wires 22.

After the stayhas been connected with the stay wire I are mounted tokreciproicate in unis'onbe-` line wires however, the presser feet are withdrawn rearwardly to the position shown in f VFig. 6 in-order topermit the line `wire and the Yattachedstay'to be advanced or elevated .in Order that the succeeding stayjmaybe applied, the presser feet being thenreturned to normal position to aidl in the application Y of said succeeding stay.

Extending across` thetwister table adj centV to the front side thereof'is a stay wire table 51, F igs.f4 to 8, the .upper surface of which is flush! with or slightly Aabove thev upperends of. the pins -24-when the'latter arefin their 'elevated-positions. The rear edge 52 ofthe table 51 is located in rear of the positions occupiedV by thepins 24, seey kFig. 8, to permit which the rear'edgeofthe table is indented by arcuate recesses'53 con centric with and having a radius substan@ tially equal tojthe` radius of the adjacent twisters. Supported-above the stay-wire table 51 isv afco'mbine'd stay-wire guide and feed-bar 54 connected to the presser-foot-bar Inl the underv side l stay wire guide 0r groove'56 which, in the normal retracted position of the feed.bar,.is disposed opposite a stationary stay' wire guide 57 fixed to the/twister table 4beyond the right hand endy of the feed bar, see Figs. 1 and 8. Y

Beyond,v and in spaced relation to the guide 57 is another stay-wire guide 58 through which a stay lwire 59 Yis led from a suitable source (not shown) to the guide 56 in the feed-bar 54. The feed-bar 54 is guided in its transverse movement by voverhanging guides 60 secured at' their front ends to the twister table V4, see Fig. 8, and engaging transverse grooves 61 in the feed. bar. y

V'At the right-handk endof the feed-bar is disposed a stay-wire cutter 62 arranged to pass across the inner end face of the guide 57 and thus sever thestay from the wire 59 Y as the bar54 moves rearwardly toV carry the stay to the twisters. Y The movement of the feed -bar 54 and the presser feet 39 trans# versely ofthe .twister table 4 is .effected through the instrumentality of *aV camV 63 keyed to the twister driving shaft 26 and engaged by a roller 64 carried at the lower end of an arm-65 secured to a rock shaft 66,

see Figs. 1 and'4, saidV rock shaft being equipped with several additional arms 67 connected by links68 tothe bar 5 4. The cam 63,` moving with the twister driving shaft 26, serves at the proper vtime to rock theshaft 66 and thusreciprocate the frame including the presser foot bar 49 and the stay wire feed bar 54, as heretofore stated.

Extending forwardlyA from the presser footbar 49 are tension ,members 69 adjustably secured to the bar by bolts 70 and having their front ends disposed opposite shallow notches or depressions 7l inV the Arear face of the stay wire table 51, see Fig. 8.

f These'tension devices or bars 69 are designed Vwith the table 51 are a plurality of stay wire depressions 72 in the form ofinclined blades carried at the rear ends of spring Shanks 73,

Y the front ends of which arecurved back, as

the stay wire longitudinally to the feed-bar,y 54 from the spool.v rllhis mechanism will Yshown in Fig. 11,'vand bolted to the twister table 4. To accommodate the depressors 72 the stay wire table 51 and the feedbar 54 are provided at their rear edges with open# ended slots or notches 74 and 75. The bottom face 76 of the depressor 72 is'slightly inclined from the horizontal in order that as the stay wire is depressed it will also be urged forwardly into engagement with the front face of the table 51.

The various mechanisms which Vdirectly contribute to the application Vof the,` stays to the line wires have now been described, with the exception of the means for feeding therefore now be described, and the operation of applying a stay will then be recited in detail. Y

T his stay-wire feeding mechanism includes upper and lower spur-gear wheels 7i' and 78 having annular rims 7 9 between which the stay' wire is designedyto be clamped at a point between the guides 57 and 5S, see Figs. 'l and 3.A The lower wheelv 78 is carried by a shaft 8O jouriialed'in suitable bearings 81 carried by an extension 82 of the main frame. tinuously driven, in 'a manner to be dei scribed, and therefore the stay wire will be continuously fed longitudinally, unless pro vision is made tothe contrary. ITherefore, the upper wheel'77 is mounted on an eccentric S3 formed en a stub shaft 84 journaled in al bracket supported by 'the machine frame. Atthe front end of the shaft 84 is fixed an arm 86 through the outer end of which is passed a vertical draw-bar 87 provided at its upper end withafnutY 88 be? tween wliich and the arm 86 is interposeda spring S9. The lower end of the bar 8T is connected to an arm 90 at the outer'endV of a rock shaft 9i journaled in a bearing 92 secured to the side frame 3. The vshaft 9i is provided at its inner end with an arm 93 provided at its extremity with a roller 94 arranged to .be engaged and opera-ted by a cam 95 carried and operated by the twister driving shaft 26, see Figs. l, 3 and'12. j

The cani 95 is of laminated forthcom-` prising a series of plates, preferably three `upper wheel 77 into position" to clamp the The shaft 8O is con-v ini number, 95a, 95h', and 95, designed tolle-e -l adjusted upon the shafty26 as'an axis, for the purposey of lengtheningor .shortening the length of the dwell 96 formed by their outer edges which are` concentric with the. shaft. plates comprising thel cam 95 may be effected in a variety of ways,'but by preference, Vone of the plates is keyed to the shaft 26,` as shown in F ig. 12, and certain or all The adjustabilityv of the several of the plates are provided with arcuate slots 9T for the accommodation of clamping bolts arigid structure for rotation by the shaft 26 after the plates have been properly. ad-v justed. Also extended laterally from the shaft S4 is second arm 86a, from which ,98 designed'to clamp the plates "together in depends a hook 86h attached at its lower end to a spring 86c secured: to a bracket 86d bolted to the member S2. "The arms 86 and f86a extend in opposite directionsV from the shaft, and the spring 86c tends constantly to draw down the arm 86'al for the purpose of rotating the shaft 84 to a position which will elevate the eccentric 83. y Normally, the

wheels 77 and .78 are ineffective to feed the stay wire longitudinally, for the reason thatthe upper wheel is held inanelevated position by reason of the elevated location of the eccentric 83. At a predetermined period in the movement of the shaft 26, however, the cam 95 'engages the rollerv 94 at theA outer end of the arm 93, thus swingingthe latter and rocking the shaft 92 for the pur-Y ,1

pose of depressing the arm 90. rlhe depres sion of the arm 90 depresses thel arm 86 h through the medium of the draw-bar 87 thus rotating the shaft 84 sufliciently toy lower the eccentric 83 and thus 'lower the wire'- between the two feedingl wheels. As'

soon as this clampingaction 'on the wire is Y' effected, the rotation of the wheels v7.7 and u 7S effects the longitudinal feed ofthestay wire to the feedbar 54. By reason'of the fact that the spring 89 is interposed between *A the arm 86 and the nutSS, the upper wheel "77 may yieldagainst the resistance of the spring 89,`as maybe necessary to accommodate slight irregularities 'or bends in the stay wire.

` The operation of thev mechanism thus far wires 22 and thestay'wire having been fed longitudinally to the feed bar 54, during the application of suchstay, the' cam 63 will operate in the manner heretofore described 'f through the medium of the'rocl; shaft 66 to shift the feed bar 54 and the presser foot bar 49 rearwardly from the position shown in Figs. 5 and A8 to that shown in Fig. `6c This operation will withdraw the presser feet 39 froml the line wires and the applied 'l n i3o-v stay, so as'to permitA the upward 'advance of i-io the linewires for the purpose Vof raising the previously Vapplied stay from the twisters and to present the line wires in position for the application of the next stay. Viis the' presser feet are moved rearwardly to permit the feed of the line wiresin the manner v stated, the feed bar 54 will also be moved rearwardly, which movement will serve first to sever the stay fremthe stay wire 59 by the. movement of the cutter 62 across` the Yleft-hand end of the guide 57, see Figs. 5

and 6, and continuing for the purpose of advancing the stay'guide 56 in the bar 54 to a position immediately beyond the rear Yedge*` of the stay wire table 51. As the lower side of the guide 56 opens through the bottom of the dropping ofthe stay from the guide 56 r Vplied to theelinre wires, thelatter will have time restorerthe presser feet 39 inA normal ir 7 a.

cooperative relation with the twisters. forward movement of the bar 49 will also the feed bar 54, the stay when presented beyondthe edge of the'table 51 will drop from vthe guide, unless frictionally retained therein. It is for the purpose of insuring and its proper location directly upon the twister table at ythe rear edge of the stay wire' table 5l, as showiiiii Fig. 11, that the depressors 72 are. provided. It will be noted, by reference to said figure, that as the feed bar 54 moves back, those portions of the stay extending across the notches 75 in, said bar will engage the front inclined edges ofn the depressors v72, thus elevating v- Y the latter against the resistance of the spring Shanks 73 'until the stayis moved beyond theV rear edge of the stay Vtable 51, at'- which time the stay willbe located below the inclined faces 7G of the depressors. The

,stay being now unsupported will Vbe forced out of the Guide 56 bv the de Dressers 72 the 'inclination ofA the faces 76 of which will.

serve to Ycause the stay to be retained closely adjacent tothe rear'face of the table 51, see Figs. Gand 1l.` ln'this position Vof the stay, which is that shown in Fig. :7,'it'willp extend across the several twisters 7 in rear of. looping' and wrapping pins 24. By the time the stay is thus located in position to be apadvanced the applied stay VVto a position above the plane of the prsser feet` 39 and the cam 63 will. retractthe feed bar 54 and.

the presser foot bar 49 to normalvposition. This will restore the guide 56 in position to receivev aiiothei' stay, and will, the same The cause the tension devices 69 Vto clamp the stay against the rear side of the stay table Y lbeyond the opposite ends of the compley stay thus positioned, and during such ap- Y ment of twisters, seeFigs.V 7 and 8. rlhe twisters will now be operated to apply the VVplication, the mechanism for feeding the stay wire 59 longitudinally will operate to Vpresent another stay tothe feed bai', so that,

as soon as the application ofthe new scayis in a plane slightly in rear thereof.

completed, another stay may be imme-V diately advanced laterally to the twisters in the manner just described. y

The order inwhich the twisters operate rhas-already been described. The operation of a single twister will therefore be detailedat this point, and it willbe understood that Y,

the descriptionl will apply to any twister,

Vsince their operations, while not coincident in point ofrtime, are the same in point of function.

When the stay has lbeen properly positioned in rear of the pins 2,4, theV gears 27 of the two middletwisters of the comple.

mentwill engage thetwist-er pinions 16, and the twisters will begin to rotatel in opposite directions. The pins 24, moving with the twisters, will engage the stay and move the same rearwardly, until the latter is arrested v i by the guide pins 99 one of which, see Fig. 8, extends upwardly from the table 4.at the outer side of each twister, the series of pins being preferably arranged substantially in a line intersecting the axes of the twisters. This initial movement of the twister will present the parts substantially in the positions Aindicated in Fig. 18, the stay wire being abutted against apin 99 atone side of i the axis of the twister and against the stay wire abutment 46 formed on the presser foot, at the opposite side of said axis. vThus further rearward movement of the'stay rwill be resisted by fixed abutments at opposite sides i of theV pin, the line wire 22 being located adjacent to one endV of the abutment 46 and lontinued movement of Vthe twister will therefore cause the pin 24, to flex rearwardly that portion ofthe stay lying between the two abutments and as the rearward movement of the pin continues, that yportionof the stay` carried backwill assume the form of a loop,

as shown in Fig. 19, the slack forithe formation of said. loop being providedby the indrawing of the stay from one end thereof` Attention is directed to the fact, however,l

that as two twisters are operating simultaneously-in opposite directions, the slack required for the formation of the two loops will be provided bythe indrawing of the stayV from opposite ends thereof. Before returning` to thel operation of the twister; at-

when the twister has approximately reached the position shown in Fig. 19, it will have Y `tention'may also' be directed to the fact that taken'the slack required forthe formation the formation ofits loopbeforetheV next adjacent twistery toward the outer Vend of the stay begins its operation. Y now, to the operation of the selected twister, which we left in the position shown in Fig.

19, continued rotation will cause the looped' i ordoubled portion of, the'stay to be urged downwardly by the depressing cams 47 and 48 on the under side of the presser foot, so that, by the time the sharpened edge A11 of the opening 10 in the twister reaches a position slightly in rear of and practically parallel with the abutment 46, the looped portion l ofthe wire will have been sufliciently Vdepressed, see Fig. 16, to cause the edge 11 tov ride over the looped portion of the wire. This position of the partsis shown in dotted lines in'Fig. 19, and at this point inthe operation of the twister, the pin retracting cam 37, see Fig` 4, comesinto action, swinging the adjacent lever 33 and depressing .the

collar 23 to withdraw the pin 24 in a down so that said loop will be' caused, by the continued rotation of the twister, to pass under the beveled or undercut edge 11y of the opening 10, as shown in Fig. 20, after the pin has been completely rwithdrawn from the loop.

The loop, having been formed and depressed below the surface of the twister, willV now be located in aplane where it may be passed under the straight portions of the stay wire and wrapped around the line wire by the continued rotationof the twister. Thus the positions of the parts shown in Fig. 20 are those assumed when the twister hasmade practically a complete rotation, 'the loop having been formed and depressed preparatory to being wrapped upon the line wire. in Fig. 21 the parts'pare shown in the positions they assume after the twister has made another complete rotation, which, it

will be noted, has restored it to normal p'osition 'and has wrapped the loopof the stay the :slipping of the` fabric which would be incidental to' the-.employment of A a drum wire tightly around the line wire, itbeing Aobserved.that the camr 37 retainsthe pin 24- in its depressed position until the operation Vof the twister reaches ra point which will permitthe elevation of thepin withoutdan-V ger of its interfering withA the stay the twister rotates. At such time the cam, passes beyond` theroller on the .adjacent lever 33, and the spring 25 elevates the collar 23 and restores the pin to its normal elevated position, shown in Fig.' 14.y As soon as the last pair o-fltwisters, to-wit those at the extnenieV ends ofthe complement, complete their opT f erations, the application of the stay tothe Returning As the pin moves down,v

line wires rwillbe `complete, andthe presserrv feet will be withdrawn rearwardly inthe manner heretofore 4described to allowlthe lineA .wires to advance,a new 'stay being placed across the twisters by the feed bar 54 advanced simultaneously with thev withdrawal of the presser feet,`as described. The presser-feet and feed barl willthen return to their normalpositions, and the'newstay will` be Yapplied in the manner described,the application starting at the centerof the stay` and progressing outwardly towardthe ends to the other of lthe stay in the usual manner.

Having now described the 'mechanismf thereof, insteadof lproceeding from bne end Y whereinl the fundamental! novelty of my in-4 vention resides, I will next proceed to describe the mechanism whereby the line wires are guided to the twisters, thef-various drums contributing tothe proper feeding and storage ofthe completed fabric, and

This form of drum is desirable for the reason'that while its form'is approximately cylindrical andysdoes not Crimpthe line wires, the engagement ofsaid wires at separated 'points' byfthe. bars or tubes 106 serves i to secure an-effective frictional contact-:between thefabric and the ldrum and -avoids havinga smoothfcylindricalsurfacel Located *inavv plane below-and in rearof the drum 101` isV a crimping v drumV 107,v V aroundthe-under side of whichthe'fabric passes fromthedrum 101.,y Thecrimping drum isV mounted on a shaft108 journaled i at the ,upperedges of the side ,frames 3' and 4. The vpurposeof this fcrimping drum is to crimpA theline'wires 'of thefabric to providey forV thecontraction and lexpansion of and operation are substantially disclosed in 8 Patent Yo. 745,801 to Dwiggins, hereinbefore identified. L f

Extending between the heads 109 of the crimping drum at the periphery thereof, are fixed bars or slats 110 having coincident series of radially extending pins 111. Intermediate of the fixed slats or bars 110,

which .are held rigid by bridge Vplates 112,

`are disposed reciprocatory crimpingV bars l113 provided with crimping pins 114. Each Y of the movable crimping pins 1.14 is in staggered arrangement with the adjacent stationary pins, as shown inFig. 1, to permit the line wires of the fabric to pass between said pins in an'obvious manner. After the line-wires vhave been engaged by the (pins, Vthe rotation. of the drum will cause the crimping bars to be reciprocated in` succession by fixed cams 115 secured to the frame of the machine at opposite endsof the drum and disposed to be engaged by rollers 116 on theV opposite ends of the crimping bars. As the stationary pins constitute separated abutments for the line wires, the reciprocation `of a crimping bar will cause the pins thereon to pass between the adjacent pairs of stationary pins and thus crimp the wire, the bar being subsequently retracted in an obvious manner to present the pins in normalposition.

From the crimping drum 107 thefabric Ypasses over'a rearV drum 117 constructed Y and mounted in a manner. identical with the construction and mounting of the front drum 101, but located in a slightly lower' plane, shown in Figs. 2'and 4.. From thel rear Vdrum 117the fabric finally passes to the usual reel 118 journaled in the rear side ofthe frame at a point considerably below "the rear drum. Y

The driving connections 'willfnow be Y traced. The main driving' shaft 119 of the vmachine is journaled at the` rear-sideV of` the frame, as shown in Fig. 2, and power is applied thereto 'in any suitable manner,

as for instance by' a belt 1-20gextendingpto aline shaft or other suitable source of powernot shown. Keyed or otherwise fixed to the driving shaft is a pinion 121 meshing with a comparatively large gear wheel122 keyedV to a shaft 123 extending between'. the side frames Y2Y and 3'. Also mounted on theshaft 123 .is-a pinion 124 meshing'with a large gear wheel 125V keyed to vthe left vhand end of a shaft126v journaled at the lower edges of the side frames.` Y Y YKeyed to the shaft 126, just inside of the side frame 2, is a beveled vgear wheel 127,-seeV Figs. 1 and 4, meshing with va bev- Veledpinion 128 at the rear end of a countershaft 129 vprovided -atits frontend with a pinion 1,30 meshing with asimilar pinion 131 on the' twister driving shaftv 26. It

will thus be seend that a gear'jcon'nection is established between the continuously opery longitudinally.

'- l Itwill appear fromwvhat has been Ysaid Y that the line wires are intermittently adating driving shaft 119V ofthe ,machinev and thetwister driving shaft 26,Y which latter therefore Vrotates continuously. lt is to be understood, however, thatI do not consider this particular form of gearing to bev essential, as any other mode of transmitting motion to the shaft may be substituted in lieu thereof. r

Continuous motion isv also transmitted lto the mechanism for feeding the stay wire This is accomplished by providing a pinion 132 at the rear end of the shaft and inmesh with a pinion 1.33

membered. that the feed of the line wires and fabric is intermittent, since the line wires` 'on the shaft 123, see Fig. It will be remust be stationary during the actual application of the stays thereto. To secure this intermittent feed, star'wheels 134 are fixed to the opposite ends of the shaft 108 of the crimping drum and areV providedk with rollers 135 disposed to be engaged by tappct arms 136 fixed to the shaft 126 adjacent toy .the opposite ends of the latter, see Figs. 1,

2 and 3. As the shaft 126rotates, the tappet arms thereof will effect the intermittentV rotation of the star wheel 134 in an obvious manner, thusv effecting the intermittent yro- Itation ofthe crimping drum, the movement of the latter being inaugurated as soonas the twisters have completed the application yof a stay, and 'continuing until the stay. vwires have been fed asufiicient distance for the medium'of:sprocket chains 140passedV Motion is transmitted from the shaft 139 Vof the rear drumpto the reel-118 through f around sprocket wheels 141 lkeyed `tothe j y shaft `139 and around sprocket pinions V142 keyed to the shaft of the reel118. Motion is transmitted to the cam shaft'38 from the twister'operating shaft 26 through the medium of gear wheels143 and144keyed to the leftvhand end of said shafts and meshing u .12o-1' withan intermediate pinion 145, see Fig. 2.

vanced, that during' the intervals of rest the stays are applied,and that during the intervals of movement succeeding portions of 'Y the completed fabric rare `stored upon theV reel. yIt will further appear that the operation of the machine is entirely automatic, that a stay is presentedto all thev twisters simultaneously,'that the operations of-corre'- sponding twistersof different series are completely coincident, and that the oper.

ation ofeach vsucceeding twister of a series` is only retarded suiliciently to allowxthe twister next precedingto take sufficient slackA .for the formation of its loop. From this it necessarily followsthat the capacityV of the machine is greatly increasedbeyondlthe capabilities of machines of this type heretofore'devised, and thatthe machine is ren. u dered morey durable and efficient by the? elimination ofthe reciprocating carriagel upon the operation ofwhich this type of machines` has heretofore depended.

It is thought that from theforegoing, the

construction and operation ofv the machinel constructedin accordance with my inventionp will be clearly comprehended; but, whilethe illustrated embodiment is thought at this time to be preferable, l reserve the right -to effect such changes, modifications, and variations of the illustrated structureias may come fairly within the scope of the pro'- tection prayed.` 1 What I claimisrfl.
