(GRANTED UNDER THE rnovisrons er ann Aer or MARCH s, 1921 A1 STAT. L., 131e.)

To all whom t 'may concern:

Be it known that l, ARTHUR. E. BLAsI-IILL, a subject of the King of Great Britain, residing at the city of 'Vestmount in the Province of Quebec, Dominion of anada, have invented certain new and useful improve-y increase the. efficiency of machines for this' purpose and reduce the weight of the operating parts thus enabling a higher speed of operation to be obtained. ri further object is to produce a fabric having greater durability.

The invention may be said briefly to consist of a machine comprising a series of distinctlock-forming mechanisms, means for causing the metal from which the lock is 'to be formed to enter the lock-forming mechanisnis, and operating means common to the series of lock-formers. More specifically stated the invention may be said to consist of means whereby the wire from which a staple 'is formed is fed in a direct line to position to be cut and formed into a staple, means wher by the staple thus formed is guided or controlled and advanced while lying in the same plane in which it is formed to posit'on engaging the intersection of the wires;

series of independently carried and relatively adjustable lock-forming mechanisms whereby a lock is formed and simultaneously canned to lock the intersection of a pair of wires; a feature in conjunction with the means last mentioned being that cach lockforming mechanism includes as a compenont part a safety device automatic in its action. A further feature consists in combining with the machine parts proper a device having the dual function of a coiler and a tension device, thus obviating` the use of a separate tension and thel separate ceiling or crimping devices. A feature of the invention consists of means whereby the stay wire is fed continuouslythat is to say, is-

projected from the feeding means continuously-the wire thus projected being stalled however during a momentary period while being eut, `and in combination,l withfthis means 'I provide means whereby the staywires are cut into stays lof predetern'iined uniform length, another novel feature consisting of this last-mentioned means being that the feed devices are prevented from'injuring the galvanizing on the wire while `it is being cut. Other features n consist of `fa particular combination of parts whereby the shft-ing of t-he stays from the positionto which they are fed to weaving position facilitated; means for facilitating the twisting of the stay-wire around the top land bottom strands; means for taking up the webas it is woven; and the' invention also conssts Of the combinations, construction, and "theI par# ticnlar arrangements of parts hereinafter described and illustrated.`

For full comprehension, however, of 'my invention reference mustv behadtothefaccompanying drawings forming a partfof thisspeciication in which similar reference'v characters indicate the same parts, `and wherein: n Figure l is a front elevation of'iny iinproved wire fabric machine; l

The machine frame consists of

frame members

2 and 3, united by a pair oi'

upper beams

4 and 5 and a lower beam 6, the upper beams serving as tablesfor supporting parts of the operating gear to be presently described. The machine member 2 has a slideivay 2a covered by a cap 2b and a boss 7 overhanging open horizontal frame portion 8- having an arm 9 supported from the base by a column 10. rlhc tables 4 and 5 have fastened thereto the series of lool: formers, by which a series et' locks are formed and simultaneously made to lock together the intersecting strands and stays Which are indicated at 12, 14 and 15 and 20 respectively, the

reference numerals

12 and 14 indicating the top and bottom strands respectively and 15 the intermediate strands. The lock formers of the series are the same in every respect, and consequently only one need be described.

Each lock-former comprises devices tor feeding the locking-Wire, cutting staple lengths therefrom, and forming them rst into staples and then the staples into locks embracing the intersecting strands and stay- Wires. 'The devices are all located in a carrier rigidly secured upon the tables 4 and 5. Each carrier consists oi a box-like casting 25 having an angular extension 26 oi substantially inverted T-form, one flange 27 ot which is ot greater depth than the other 38 and formed with an upright flange serving as a guide for a plunger 30 by which, in conjunction With an intermittently hori- Zontally reciprocatory pin 31 (to be hereinatter further described), the staple is formed. The end of the angular extension opposite to the box-like member is turned as at 27"L to extend at right angles to the table portion 5 upon which it rests. The

connection between the extension 27a oi each casting and the table 5 consists of a series of spaced grooves 500 and a f 501 inserted half into either one ot' a pair of grooves 502 in the underside et the extension and half into one ot the grooves 50G. rlhe grooves 500 illustrated in dotted lines, Figure 10, and 502 are, respectively, spaced one half inch and one inch apart in order to enable a one-halt' inch adjustment to be had; these parts being in this manner held against displacement in parallel planes, ative displacement at riglt angles being prevented by a bolt 505. This plunger 30 consists of a member et oblong cross section each side edge having a tongue 28 and one end being reduced in thickness as at 32, While a flat groove 33 extends throughout one side and is deepened as at 25%, sce Figure 15, Within the thicker portion of the plunger. The groove accommodates and acts as a guide for a second plunger by which the staple is yforced into dies for forming it into the lock. This second plunger consists of a flat bar 40 formed with1 a 'fixed die is indi Menzies lateral hook l1 engaging a hook 42 on cross-head 13 having side flanges it in alineinent with the sides or' the plunger bar 40 which is ot greater' width than the main body ot the cross-head. The plunger-bar is guided in the flat groove and the crosshead in the deeper portion 29 of the groove. The width or the plunger 30 from the plunger L10 to the bottom is equal to onehalt thelength required tor the sta}' leblank, the bottom and toptongues Q8 Vslidalily engaging the groove formed by the flange 29 and a corresponding groove formed in a cap 15. The cap extends trom end tol end of the angularl extension 2G to the top oi which it is secured by screws 28a.

The staple formed by plunger 3() and pin 31 is toi'ced by plunger 1-0 into a matrix presented by a pair oi dies carried within the adiacent end oit the member E25, one die being xed and the other movable. The lated at 50, and it is secured by acapscrew 51, or othersnitable means7 to the interior of the endr ot the boi; and held against vertical displacen'ient, The particular formation of the matrix face oi' this die will be presently further described. A slot extends .tronir this matrix 'tace through the die in alinement with the guiding slot for plunger d() and such face is grooved as at 61 and 62 to accoi'nmodate the intersecting stay-wire and strand. The movable die indicated at 353 is mounted in the end of a slide 70 by a vertically, disposed dovetail connection 7 This slide located within the boxelike casting 25, the 'free end or which overhangs the beam l 'and is toi-hed as at 72 to afford* bearing for a shaft 73 to be presently further referred to. Upon this shaft is rigidly mounted a cam 74 which bears upon trundle roll 75 mounted rotatably upon a iffransverse shai't 7 6 the ends of which are coni'ined in horizontally disposed forked.

an extension of the link-member 7 8, a setscrew 94 extending through the link-member and bearing upon the bottom ot the' box for the purpose otadjusting the degree to which the toggles lie ori-center. The link 7S is connected to links 77 by an ad- 'justable member 78 pivotally connected to the links 77 by a pin 90 and a rightand-le'ft-hand screw 91 connecting the mem-V bers 78 and 7Sa together. This screw affords means rfor adjusting the length between the shaft 76 and pin 79 for initial ifittingand to take up the wear between the cam 7 l and litecte'd by a'laterally inovablebar 100 coinmon to all the lock-formels. This bar will be hereinafter more fully described. The face of the matrices are termed follows The matrix has a pair of curved groovesy oet cofacting `withgrooves in the face of matrix 50 and apair of grooves o 66 andf 67 in each matrix face accommodating the strand and stay-wire respectively; v

while the matrix t'ace 63 has a.

pair oi concavities

68 and 69 to accommodate the ends of the staple. i

Before kthe staple can be vformed a wire blank length must be cut and fed ,to posi-v tion to be acted upon by the staple-kilorniing plungers andthe cutting thereof is done partially in advance of and partially simultaneously with the commencement ot the staple-forming operation, the cutting being effected by a plunger-'30 in shearing relation with bushing 181 through which the wire is fed. This `wire is hereinbefore kreferred to as a locking wire and is indicated at 180. fitter it is ted t irough the bushing 181 it passes between the pin 31 and the Yface of kplunger 30 through a iiared `eye 182 `in the cap Ll5 to a stop consisting of the overhanging end 183 of a small oii-setbar 1811 fastened to the cap over the eye, bysci'ewslS. The feeding of this wire is done by a pair or feedrolls 20() mounted on

shafts

201, 202 theformer being driven by bevel-gears 203 common tothe differentlockorniers and vhereinafter further described in connection with thenoperating ymeans commento the several lock-'formerav These reed rolls are disposed to eedvertically, and located beneath and with their direction or feed in supported in a bracket :2.10 secured to the'bot tom or the member A bundle or this wire bent to form the staple has` itsoperating end 31L reducedvin width sniiiciently to pro? vide Ispaces at the top and bottom sides thereof and betweenit. and thetop and bottoni walls or the lgroove or slideway 33 suilicient to accommodate the legs or the staple. This pin is operated by a `bell-cranl-lever 250 actuated in turn intermittently by a bar 2419 secured by screws 251, for instance, to the widened portion of the plunger., such bar having lingers 25:2 and 258these lingers engaging the protruding end 254i of the bellcrank-lever andshitting` it and tne pin upon each reciprocation of the plunger.

Eachlockfformer also has two pairs of kralineinent with the bushing 181. They are 'Y isok eil

together as the slide advances by the swing,

ing of the fingers, and this is caused and the 'lingers made to open and close to a line intersectine; the line of feed of the strand by cam slots 201 therein and pins 262 engaging the slots and carried by the slide 70. rllhese lingers are for guiding the strand wire and bringing' it into alincment with the matrix7 an opening' worlrV permitting` the strand to pass, spliced portions of such strand beingalso accommodated and the woven fabric being permitted to swing' free of the fixed die, as will be hereinafter shown. The stay wire 20 is guided in a guide consisting` of an integral part 300 of the cover l5 and preA sentinfr a leaning` standard 301 with a latch SO2 pivotedthereto as at 303, suchlatch having` a jaw 304e with an interior shoulder beveled as at 305`r the jaw being; Irooved at 306, the end of the groove towards the direction from which the wire comes beingv flared as at 307 to facilitate the entry of the wire. T ie latch is yieldingly held closed b v a spring' 308 and bolt- 309 the latter attached to the latch, and the spring` bearing' between a nnton the bolt and the standard.` The wire is forced out of this groove by a cam carried (with as many more as may be required) upon and operated by a shaft 312 common to all of these cams and to be hereinafter alluded to. This cam consists of a plate 310 formed with hub 311 fitting upon the shaft and secured thereto by a spline and set-screw 3M. rEhis shaft is driven from the shaft 212, and at the same speed as it, by sprocket-wheels 890 and chain 391. Aswill be presently shown. during the downward movement of the cam with the shaft it bears upon the stay-wire 20 and coacts with the other cams in forcingv the wire into the matrices. For this purpose the bearingf face of the cam of a configuration to force the wire from the guides 306 to the matrices and before' this action the predetermined length of stay wire is measured off and si inultaneously with the commencement of the movement of the wirer it is severed rilhis finishes the description of oneof the lock-forming' mechanismsy and as before mentioned there are siX of such mechanisms all identically the same.

These lock-forming;` mechanisms are operated in unison by means common to all as follows T he several feed devices y (rolls 200, etc.) receive motion from the shaft 20/lbefore mentioned, the motion being` transmitted through the gears 203 also above 270 in thc bottom of the frame mentioned and through it and pinion 121 and shaft l20vfrom initial power represented ly pulley 12S. The gears 207 and are mounted on one and the same stub shalt the gear 206 on a different stub shaft. and the gear 205 on the shaft 204i, and the gear 209 on a shaft y212 transmitting` power to the stays-wire twisters to be hereinafter further alluded to.

The stay-wire is drawn from a coil (not shown) suitably located and across the several l ocl -formers and' through the ,guides to 'position 20, and measured and eut olf by the followingY means: Stay-wire 20 is supported and guided between the guides 306 of each lock-former by intermediate guides comprising brac iets G00 having a member 601 corresponding` to the standard h and having` a latch 602, and coaeting cams 6l() on shaft 312. The se-vering of the stay-wire is done by a cutting' tool 320 mounted rigidly upon a collar i023 secured Upon a shaft 31.2 and rotating in shearing relation .vith a stationary cutter 132]. counter-sunk in a bracket 322 and fastened Athereto by a clamp 1822, the bracket being fastened to the frame member 2 by cap screws 1324-. a bushing 321 in the bracket servingy as a guide for the wire which is drawn from a reel suitably' located` by a yielding feed device.

This yielding' feed-device consists of two pairs of feed-rolls 33,0331 mounted in a carriage horizontally slidable on a slide Sell bolted to the lun` 322, the carriagey beingn constructed to partially enclose the sliden the edges of which are rabbeted and ene b v the enclosin edges of the carriage which are. also rabbeted as at M5. This carriage consists of a casting Sil-0 and a plate 346 in the space between which the feed rollers and two pairs of driving' gears and 336 are mounted on

pins

350, 351, and the opposite ends of the lower pins (i, 358), being` diminished and set in holes in the casting and plate while the upper pins (350. 852) are secured in place by set-screws 360` by which may be secured adinstinent to regulate the pressure of the rolls upon the wire. This carriageis caused to move in one direction by the feed rolls creepingv along the wire during the interval that its progress is arrested by the operation of the cuttingtool 320; and it is returned to its initial position by a cam 370 operated by shaft 175 upon which it is rigidly mounted`r the cam acting on a roller 371 on the carriage.4 This creeping back of the carriage provides for a continuous rolling of the feed rollers along the wires which has the advantage of obviating abrasion of and damage to the galvanized or plated surface of the wire. The end lof the il o ` Ytei-ent lengths.

shaft 312 upon which the cutting'tool 320 is moui'ited is supported by bracket 322. The driving 2sears i135 and 336 ofthe feed-rollers 3330 and 331 have hubs upon which the rollers are ii'iounted aiiil-iii'rli irearsare driven by a pinion 335i niounted rigidly en a shaft 339 (nirnaled in the carriage 'ind hai'- ing mounted rigidly upon oul end thci'eo' a sprocket-wheel Settle Vilbya sproclset-whee div and sprocketchain T02. .This shaft driven by a pinion 'TO3 rigidly mounted therffon and a `geur 'Oeir 'ide enough ot race rto interim-ish with the piiiion TO3 and a measuring gear "[05 ,iiioiii'itA ed rigidly on the shaft (before inention' ed), This gear Ulli, `for the purpose ol :id-

IThe spi'ocleewhe'el on'shaiit 852is operatively connected rto the shattbya friction rclutch 860 having a brake 861 combined therewith in such ai manner that when the clutch is thrown out theibrake is thrown-in.v yThis action is 'brought about by a cain 862 on shaft 175 and operating' a lever and rod.

inechanismSGS which 'in turn 'operatesA the clutch (and simultaneously the brake) the clutch being` thrown in simultaneously kwith cen'unencenient oi2 the elevation of the woven ytence fabric? and thrown` out slightly in advance of the linish o'f the elevation. The effect otthisv throwing-out ot the clutch at this' particular time is that the 'wires are held and the required tension is imparted `thereto to ensure u'niforii'iityof lengthof the several strandsabout to be locked. Another function ot the tension isthat when the take-up to be presently described) operates, the relative arrangement of the parts and holding ot the lower ends of the strands throws the locked intersections of the woven fabric out of the fixed matrix, Thisrnoveinento the fabric is accommodated by the `opening- 270 in the Lbottom of the frame'o't- 'ther machine. kThe use oi" this combinedk ykcoller;and `tension mechanism is rendered possible by the 'presence in the niachine'o't the ceutralizing` ngers() which overcome the tendency oit the 'spiral wires to detiect from the grooves 66 in thel matrices and springs them into line. l

The top and liiottoin strands have the ends ol the stay-wir s 'twisted around `theni by 'means oi twisters each j'oiisisting' ot a coilinir head 9d() having" an axial bore 901 of a size to lit thestrand wire moderately closely blut with freedom to slip througijh it. This 'bore extended laterally in the `forni of a widened chamber 902 the innerwall ofy fwhich is inclinedr outwardly.` Thestrand wire passes upwardly through the bore, and the spliced ot which there is usually one at the end ot'each bundle of wire are accomil oi" the inachinefitramef, and it is rotated by va spiral near 907 mounted rigidly thereon i' d intermeshingv with a second spiral gear 'mounted in. the betore-inentioned shaft *212.* krlhe head has a yradial hook 909, and

ciently short of the bore to provide the necessary clearance for the stay-wire- The top of the bracket has a pair of standards o r

vertical lugs

1001 and 1011 Corresponding with the standard 301 and leaning` slightly away from the axial line of the ceiling` head tor the purpose of accommodating' and forming; clearance for the elevation of the drawn upwardly. Two pairs ot cams ot the same nature as the before-mentioned cams 310 are mounted7 one pair at each margin wire of the fence, and they all work in conjunction with

standards

1001 and 1011 and have for their' function to depress the stayevires, each of the standards having` one of the spring' latches 302 carried thereby and operating' in the same manner as those before mentioned. In order to give a lead to the spiral formation of the coil, the end of the staywire to be coiled is supported on a level with the horizontal grooves 6i' in the dies 50, by an inclined bottom or seat 1005 hetween the leaning' standard 1011 and a pair ot vertical lugs 1006 located opposite to the standard 1011. rIhe pair of these cams tarthest from the t'eed rolls 330, 331, are indicated at 1010 and 10127 the cams 1010 being' arranged contiguous to the inner faces of 1011 and G andthe other cam 1012 contiguous to the standard 10015 bot-h cams being in position to act upon the end to be coiled and bend it down to lie across the top of the head and in the. path of the revolving' hcolr.- The top of the head is of conical form and in order to cause the bent-down end of thel stay-wire to assume a position lying; along` the surface of this cone and in the path of the hook the cam 1010 is shorter than 1012 and has its end rounded o concentric with the pivot ot the cani and of a rlength to depress the stay-wire end to the required extent; and the cam 1012 is ot suitcient-ly greater length to supplement the The pairo'f cams nearest to the feed. rolls are indicated at 1020 and 1021, the cam 1020 being` struc-y turallythe same in all respects as cam 1010 excepting that its shapey is reversed and it is made riglitdiand instead of lett-hand- The Cain 1021 consists ot a curved linger secured to a 'collar 1023 mounted on shaft 312, the function ot which is to carry this cani and cutter 320 before mentioned. The action ot these cams and the cams 810 before mentioned is simultaneous, and the hook 909 so timed in its action to meet the stay-wire end immediately after it has been bent down to the conical surface.

A. bar 100 common to all the loclr-tormers rests slidably on the beam 4 and engages a lug 101 on the underside of the slide. This bar is made to operatein unison with the cam 74 by a pair ot cams 102 also mounted on shaft 73 and engaged by trundle rolls 103 carried by arms 1011 fastened to the bar 100. rl`liese cams 102 co-act with the cams 74 as double leaders in imparting the required intermittent reciproca-tive operation to the die 50. This shaft is driven from a driving shaft 120 (the initial source of power in the machine) through a train consisting ot afpinion 121y gear 122, pinion 123, and gear 1241 on such shaft 73, the gear 122 and pinion 123 being` mounted on an intermediate shatt 125; and the driving' shaft deL rives its power troni any available source by a combined fly-wheel and pulley 126, belt 1200 and fjiulley 1201 and counter-shaft 1223.

The plungers 30 and /10 are operated bj: a pair ot slide-bars 150 151 connected to the several plungeis by connecting` rods 152. the end of rod 152 being); `formed with a vertical pin 154- engaging a hole 155 in the crosshead 43 and the end plunger 30 .is torlred to receive the end of rod the connection being made by a pin 156. The connection be tween the oppositeends et the rods and the slide-bars is effected by pins 157 and 15S. These slide-bars are actuated in the operation ot cutting' the blank torining the staple and forming the lock from the staple by cams 160, 161 through slides 162 103 in the torin of frames enclosing the cams and carrying rollers 164? 105 beaiiing` upon the Canisn the return movement being imparted by caras 10T 108 and

rollers

169, 170; while the connection between the slide-bars and slides 1027 1033 consists o't engaging hooks 171. 172, formed respectively on the slide-bars ,and slides. These

slides

162, 103 are guided in the slideways 2 and are prevented trein upward displacement by the cap 2". These rains 10th 16h 10i" and 100 are mounted rig;- idly upon a shaft 175 having power transmitted thereto trom the shaft 7? throuo'b initrefgijears 170 and 1711 lfleietoioi'e therel has been considerable disadvantage experienced in collecting` the Woven tabric as it lett the machine. owing to the 'inet that the .vindii'ig' up or rolling' ot the iabric was of necessity done intermittently. Another disadvantage was experienced 'troni the iincreasing` diameter oil: the roll being' woundgowing tothe tact that tliev'indind' drum was caused to exert its pull directly upon the fabric in the machine, the variation in pull duel to the increasing diameter being neutralized by a `manual adjustment A c* cording to my invention the variation in pull ot the wind-up is automatically neutralized y by constant speed pulling-roll; and. means intermediate of the pulling' roll and the tabric in the machine takes up suticient fabric to leed the continuously rotating' pulling roll during` the time the gtabrie is held stationary by the clamping` Aiction ot the dies. The constant speed pullingF roll is grouped witha wind-up roll 1201 and a roll 1202-to increase inea-Ass the'extent to which the web or fabric indi` cated at 1205 is wrapped around the pulling roll. This latter roll (1200) is driven constantly by sprocket wheels 1200 and 1207 and chain 1203, shaft 1210, pinion 1209 and gear 1211 and the wind-up roll 1201 is 'driven by a bet 1220 looped around pulleys k1221 and 1222 the former on the counter shaft 1223, before mentioned, and the latter carried by the frame 1224 in which these rollers arev mounted and driving` a pinion 1225 inter meshing with a gear 1220 driving thenroll 1201. 1n order to accommodate faln'ics with. differently spaced stay-wires theshailt 1210 is mounted in an adjustable hearing 212 clamped in place by screws 1213 and adjustf ed by screw 1214. The take-up y.mechanism consists of a drum 1230 mounted rigidly on a shaft 1231 journalcd in a pair of'boxes 1232 in vertical slideways .1233 formed on the upper ends of a pair of standards 1234 braced `by

stays

1235 and 1236. rl`he shaftends extend throughathe bones and have connecting rods 1237 mounted'thereon and prf vided at their lower ends with trundle rollers 1233 which bear upon cams 1239 mounted rigidly on shaft 73. rlhe rollers and ends of the connecting rods are mounted on'a pair of kshat'ts 1243 journaled in boxes `12%0 guided in slideways 1241. The cams are timed to raise the drum during the period the dies are open and permit it to fall during the period the dies are closed. The fabric is looped over this drum. f

This completes the detailed description of the machine, and in order to facilitate the ready understandingthereof l will now set forth briefly the manner in which it/operates.

Operation.

The

strand wires

12, 14e, and 15 arek lirst threaded upwardly through the coilers 802, the marginal strands 12 and let through the -twisters 900 and the intermediate strands l5 through holes 270 in the frame of the locking mechanism and between the lockforming dies 50 and'G?) of thc various lock-forming mechanisms. From mechanisms and twisters they are all taken over drum 1230 and around thepullingroll 1200 and roll 1202 tothe wind-up roll V1201 to which latter they are fastened. rEhe stay wire is then threaded betweeny the feed rolls 330 and 331, through bushing 321 over Vcutter 1321 and through the guides 3,16 lfunthese plungers 30 (Figures 161,15, 16 and 17) advances in shearing relationwith the bush- 181 in its particular lock-forming mechanism and cuts off a staple-length, and con tinuing to advance forms the staple.

' shown in `Figures 11 and 1,5, by foldingthe endsover the pin 31 previously inserte-d in th'epath of the blank. rlust before the plun- 250thus withdrawing the pin 31. linmediately following the withdrawalk of the pin `the second plunger 10 advances and drives thestaple ahead of it towards the dies. `lust before the forward ends ofthe staple 180 pass "through the hole 60 the die G3 is brought into contact with the die 50 by means of cam 741, roller 75, and slide 70.

Continuing inr its forward movement the plunger 410 drives the staple into the matrix thus forming the lock. Simultaneously with the depression of the stays 20 by cams 310- to the position 20, the ends of the stays are depressed by the cams 1010, 101.2,and 1021, thus bringing the ends into the path of the lingers 909 by Which'these ends are `engaged and twisted or coiled as at 1909 around the marginal strand 111 (Figs-27, v23, 29, 30, 31, 32, 33, and 341).r Each coiler or twister is so timed as to engage the endl of the stay immediately it is depressed. The lockf0rming step and twisting or rcoiling step are simultaneous, and the matrices are opened immediately the lock is formed. The

loperation thus far described completes the wear/'ing of the fabric, and the elevation and the winding up of the latter is the final step. This elevation and winding up is caused by the rotation of the

drums

1200, 1201, 1202 and reciproc-ation of the `drum 1230, the latter being operated by cams 1239, and the .function thereof being to take-up sufficient length of strands to`permit them to be' held stationery in the dies from the time the dies Aare closed until they are opened again. It

must be understood that the pulling drum 1200 rotating continuously at uniform speed in unison with themachine, must be supplemented'by means forfeeding the fabricto the drum during the stat'ionaryperiod. This is done by the elevation of the drum 1230 and consequently the taking up `of the fabric during the time the dies are open, and thek lowering of the drum and consequently the jfeedingfabric during such stationary period. During this elevation of the fabric the strands are pulled through the coilers 305 and coiled. 1n order to obtain a uniformity of position of the curves produced by the coilers relatively to the stays, the coilers are driven in unison. Just previous to the commencement of elevation `of the fabric, the cam S62 through the intermediate lmechanisms described operates the clutch 360 vand brings lthe 'shaft 852 and conseger reaches the end of its stroke, the linger r25,3 (Fig. 15) operates the bell-crank lever quently the coilers into action. Before the elevation is completed the mechanism 863 (Figs. 1.4, and (l) throws out the clutch and throws .i the brake, thus stopping the coilers while the 'fabric is'still being elevated and causing them to act as tension devices. Si. feature ot this operation, due of course to the 'novel construction and combination ot parts before described, is that the lock-torming wire is `fed in a line parallel to the strands with the advantage that they (the lock-torming wires) avoid all obstructions; and the staple strucl; therefrom is maintaineduntil linal formation in thev same plane in which it is formed, with the advantage ot' simplicity of construction and operation of the machine.

rlhe gear 705 is so cut that each tooth produces one-quarter of an inch travel of the periphery of the1 leed rolls 330 and 331, thereby enabling a predetermined length oi stay wire to be :ted during the interval between the times the cutter 320 passes through the line of the wire (indicated at 20. see Fig.
