in the county of Winnebago and State of W is.

consin, have invented eertain new and useful Improve nents in Cmled-Wire-Fabric Machines, of which the following is a specifica tion.

I My inyention relates tomachines for cil-' ing and weaving wirev into a fabric-such as employed, for instance, in the manufacture of wire mattresses; and the object of my invention is to produce a machine of thischaracter which shall be efficient and reliablein operation, capable of automaticallycoiling' and weaving the wire, beginning with the wire on the reel and ending with its conver,

sion into the complete wire fabric.'

My machine is designed and adaptedto. perform all its operations with precisionand reliability, with the result that the product thereof is perfect and without the waste that would result from imperfect coilingeorwveaw ing at any point in the fabric, 'Moreoyer, my machine possesses reat capacity, and the arrangement is such t at the capacity may be increased'by increasing the number of coilers and weaving devices, so thatlohemafchine may be provided with a plurality of angs of coiling and weaving devices, producing separate Wire fabrics, but operating as a unit or as a single machine. Again, in my machine: I provide for the adjustment of the parts sothat wire'fabrics with coils of different size or pitchmay be produced. Furthermore, I provide novel and eflicient mechanism, herein designated'as pattern-racks, whereby the cords which. are arranged at the sides of a Wire mattress to form the borders and which are also run intermediate the width of the mattress for strengthening purposes may be Woven into the fabric automatically according .to any predetermined arrangement as provided for by the patternracks.

The various features of utility and advantage of my machine will be made apparent from the description hereinafter given.

In'the machine herein illustrated; as embodying my invention I have chosen to show four gangs of coiling and Weaving devices,

taneously produced;'-but itwill. beunderstood that my invention, except where specifying a plurality of such gangs, is not to be limited thereto, but that the same may be embodied in a machine employing one coiling and weaving device and producing asingle- Wire fabric.

Before proceeding with a detailed descrip-' tion of the construction and modeof operation of my machine I will state the operation briefly, as follows: Assuming that the wire fabric isto be composed of double wires, as

usual inmattress-springs, and following out the operation of a single coiling and weaving device, the two wires taken from the reels are fed by means of feed-rolls to a pair of coilers, where the wires are given the proper coiling, the size or diameter of the coil and the pitch thereof being dependent upon the size and pitch of the spiral of the coilers.

' The wires as thus coiled are brought together as a single wire and are passed through a knife or cutting device and also passed or run into a weaving-channel. After the two wires thus forming, in effect, a single wire or strand are run into the weaving-channel a sufficient distance the] knife operates to cut off the wires. In the running or extending of the wires in the weaving-channel the same are woven or interlocked with the coils of a preceding wire, after which the completed coils are raised a sufiicient distance in the weaving-channel to enable the next or running wire to be itself interwoven with the last com leted wire or strand in the fabric.

It will be understood that the feeding action of the feed-rolls is not continuous, but intermittent, and the same is true of the operatiohs connected with the performance of the functions of. the weaving-channel, inasmuch as it is evident that the coiling andadvancement of the wire must terrupted until the last wire as been oper. ated upon in the weaving-channel and been raised to a proper position therein so as to be engaged by the next or running wire in the weaving operation. y

As is well known, the strengthening-cords and border-cords character, and it is therefore essential that the machine shall provide for ause or be in arejrun in fabrics of this the running or.

consist 'simpl y of the ordinary strand of two or more wires, which are inserted in the same position occupied by the preceding strand or set of wires insteadof being regularly coiled therewith, with the result that the number of wires in a strandismultiplied and the fabric thereby strengthened at such point. It is desirable that the border shall have a series of these strengthening-cords" and that the cords intermediate should have simply a double set of strands; but in the fabric corresponding to what will become the middle line of a wire mattress it is desired that the strengthening-cord shall alternate with.the

usual strands. The construction andar rangementof my machine are such that these cords may be run or inserted in an automatic manner and according to any predetermined patternthat is to say, the number of the cords at any particular point or line,.as well as'the location thereof transversely of the mg to any'pattern which he may adopt.

Itwill be understood that the machine produces a continuous wire fabric, which is preferably received upon suitable windingrolls, such fabric of course containing the material for a number of wire mattresses, ac- .cording to the length thereof It will also be fabric, may be varied by the operator accordunderstood that the fabric in such continu-- 5 one roll contains the border-cords at intervals corresponding to a division-line between the various mattresses, which are separated, as usual, by withdrawing the strand connecting the border-cords of two adjacent mattresses in the roll or fabric.

From the brief description already given of the machine it will be understood that the same is capable of simultaneous y weaving a plurality of fabrics when gangs of coiling and weaving devices are employed. It Wlll also be understood that the fabric may be of the double-wire variety, as is the most common in commercial fabrics of this kind. onsequently in the description hereinafter given it will be assumed without any limitation that the fabric is of the double-wire ty pe, and for convenience in description the machine, will be described as if it had only a single set of coiling and weaving devices instead of the four sets or gan s illustrated i l. the complete machine of the rawings.

Now describing the machine in detail and referring particularly to Figs. 1,2, 3, and 4,- such machine, as herein shown, comprises a main longitudinal frame 1, consisting of par all el longitudinallyextendmg beams or strips, and also a side frame 2, allsupported in suitable manner, as by the legs 3. Upon the front end of the machine a head 4, adapted. r2 5 to carry some of the operating parts of the machine, such as the feedrolls and coilers, is arranged to reciprocate in a horizontal plane in a. manner and for a purpose hereinafter -1nade apparent. 'Asshown in Figs.. 1. to 3 1 0 justable, to which end the lower roll is in-the and 13 and 14, thisreciprocat'ing headis provided with posts or bearing-guides in two pairs rising from opposite sides of the machine, having between them the bearings of two feed-roll shafts 6 and 7, the purposeof which is to feed the wire which passes between them'from the reel to the coiler or coilers in advance thereof, as hereinzii'tereirplained. In the present instance the pressure-surface of'the upper roll is a shell or c l-.

inder 8ysecured to theshaft; but the roll might, if-desired, be'made in onepiece.

- 1t is desired .that one of the feed-rolls shall act on the wire with a yielding pressure-and.

also that such pressure or tension shall be adpresent instance made in a novel manner,

such roll belng, in effect, a band or ring 9 in casea single-Wire fabric is to be produced, or

in case a double-wire fabric, as in the present instance, a pair of'rings is provided, or a plur'alityof rings in case of a gang-machine; In

this connection it will-be borne in mind that in the machine illustratedfour gangs of coil mg and weaving devices are employed, in

which instance a series of eight of these rings arranged infour pairs is employed. These rings surround or encircle the lower shaft'7 and are spaced to'properdistance by means of a series of distance-sleeves 10, also encircling the shaft 9, Fig; 13 and Figss15to 17.

1 Between each ring and. the shaft is interposed a coiled spring 11, the outer end of which is fastened to its ring 9 and the other orinner end to the shaft 7, in the present instance such connection being made by meansof' keys 12, as illustrated in Fig. 13, As a result of this arrangement and construction the motion of the shaft 7 is not directly commu-.

nicated to the rings or roll proper, but indirectly thereto with a yielding pressure and, through the medium'ofthe springs, it being.

- understood that the feed-rolls should act on the wires in such amanner as to feed. them properly, but without flattening or crushing them 5 p The rings or bands are arranged in pairs, one pair for each gang and one ring for each wire, assuming that a double-wire fabric is theone to be woven or produced bythe machine. In order to obtainthe accurate adjustment ofthe rings as regards the tensio'n or pressure against the wires, the rings are adapted to be adjusted independently of their shaft, whose adjustment will be hereinafter explained, and to this end adjustable rollers '13 are arranged below the rings in such man ner as .to bear against the lower peripher es thereof, Each ringcooperates with a, pair of these rollers, ,which are mounted to'rotate in a vertically-movable cradle 14, having a depending fulcrum-pin 15. The fulcrum-pins ave bearing-points at their lower ends, and

I the pins of two companion cradles cooperate with and bear against a commontransverse pin 17 and for each fulcrum bar 16, which is sustained or sup ported at the upper end of a sin 1e ivot-pin 17,1b'earing against the under si e t ereof at a point -midway of the. bearing poin-ts'of the fu crumpins.

The fulcrum-pin 15, as well as the pivot-.

pin 17,'are movable in vertical openings'or holes in the block 17 of the reciprocating head or frame of the machine. The pin 17 is arranged to be moved with a yielding pressure, and to this end an operat1ng-handle'19 I is mounted to turn freely upon a cross-shaft I brackets 21, secured to the block 18. When i a plurality of gangs of coiling and weaving de vices are em loyed, there is a corresponding number of t ese handles, one handle for each an of rings or bands.

As shown, each han le is'provided with a projection or arm 22, arranged to bear, as shown, against the head of an adjusting: screw 23, which screws into the lower end ofa depending rod or pin 24. a This latter pin bears against the same hole or op'ening'asthe pin17; but instead of bearing directly there- 20 having its end supported in depending agaln'st or forming a part thereof a spring 25 is interposed between their adjacent ends for cushioning purposes and to yield to different variations in the w res and prevent such vanations asto one wire from affect ng-the tensionof the other wire or wires.

From theforegoing description it will be I understood that the upward movement 'ofj' {the right-hand 'end' of .the handle, Fig. 13, will move, the arm 22. away from contact with,

fith'e adjListing-screw 23, with the result that "the cradle and its roller, together withfthea-s" sociated p arts,will drop forward, thereby re-x 'lieving-its rings or bands from any pressure 1 or tension to which they had been'previously' subj-ected. By adjusting the screws 23 up or down the degree ofpressure of the rollers '13 and the;conse uent tension of the rings upon the wireswill e correspondingly adjusted I that is, increasedor decreased. Itwillbe' understood that the'handles' 19 are pivoted loosely upon the cross-shaft 20- in order that the tension or pressure adjusting mechanism for the several gangs may be independently adjusted. v As will be clearly understood from Fig, 13, an upward adjustment of the cradles and the rollers 13 will-move or adjust the pressure or feed rings to a position eccentric of the drive-shaft 7., and such rings will consequently bear it with an increased pressure ocking-ba'r 26 is pivoted to, the reciprocatinghead or frame of the machine, with its lower the end arranged. to coeperate and engage with By actuthe parts in the normal position illustrated in said figure.

The-shafts of the feed-rolls are both ad justable vertically in their guide-frames, as

. vertically in the opening in obtained, V I

clearlyindicated in Figs. 13'and 14. Referring first to the upper roll, the shaft thereof is journaled at its ends in blocks 30, movable ports or guides in the reciprocating head and resting upon the upper ends of two parallel vertical strips 32, extending along the inner sides or walls of the guides and passing through slots at their lower ends. These strips 32 extend beyond the lower-end of the guides and are outwardly flanged at their extreme ends'to fit upon the upper face of an adjusting-nut 33. This nut screws upon aplug 34, secured in an the lower end of the guide-frame, with the result that when the nut 33 is adjusted vertically the journal boxes or blocks 30 are correspondingly adjusted in their guides, the ed osition To, oldthe journal-blocks 30in fixedposition after the proper vertical adjustment is provide set-screws 36, bearing against the v screwing through bridge-pieces 37, extending across and connectin' the 'tops of the guides.- The lower feed-roll is ikewise, j ournaled at its ends inboxes' or blocks 38, which are movable or vertically adjustable between; the

strips 32, as indicated in Fig. 14. To the and in addition such tubular extension lowerendsof theseblocks are secured blocks, 39, provided with screw-threaded tubular-ex: tensions 40, which are adapted to cooperate with vertical adjusting rods or shafts 41;,

These shafts are provi ed withcollars 42, which bear upon brackets 43, depending from the guides, and the extreme lower ends thereof extend through the brackets and are provided with anan ular portion to receive a ey-wrench or the ike. ,By. rotating these adjusting-shafts in one direction-' or the other the feedroll shaft 9 is correspondingly adjusted vertically up ordown; as the case may e-i .As clearly indicated 1n-'-Fig. 14,- the ad justing-shafts, as well as the tubular extensions 40, extend through thehollow plug 34,

guided thereby.

Before reaching the feed-rolls the wires are just the position roll set-screws 52, Figs. 3 and 13.

parts being locked in the adjust by means of the locking-nut 35.

top-of such boxes or blocks and caused to pass through ustrated particularly in Figs. 1, 3, 13, and 22, for the purpose a of straightening out any kinks or bends in the wire and also for properly directing the wires before their entrance between the rolls. As shown, each wire has its own individual guide, each consisting ofa strip or substantially rectangularblock 44, provided with a longitudinal channel, in which the wire lies and runs, together with an upper strip or block 45, provided with alongitudinal rib or fin 46, adapted to enter'the channel of'the lower bar and to rest upon the wire as it asses through; Bypreference each lower lock rests in a bracket '44, secured tothe machine-frame.

of these guides, I mount them all on a cross-piece or plate 47,which is n adjustably secured to the sides of the feedguides 31 as more clearly indicated in .Figs. 1, 3, and 13. This plate has depending brackets 48, which are slotted to receive the bolts 49, secured in said guides 31. The, proper adjustment of the cross-piece or plate is obtained by adusting the set-screws 50 and then tightening up the b s. To this plate is secured a parallel plat or bar 51, arranged thereabove and adapted to receive a series of These screws are adap'te'd to bear against the upper block 45 of the wire-guides in order to regulate the position of such upper block to the passing wire and also in order to take up wear.

Thewires as they pass-through the rolls are fed to the coilers, one'for .each wire, whereby the wires are given the proper coil according to the diameter and pitch of the particular coilers employed. Each coiler comprises a coiler proper, consisting of :1 cyl-- inder 53, having a spiral roove 54 cut on its periphery and of the 'itc' to be imparted'to the wire, Fig. 23. T is coiler is incased in a shell 5 55, and such shell and its coiler are held in proper relative position and such parts are-also held in fixed position in the ma chineby means of a pin 56, passing through a plate-57 on .the machine and extending radially .through the shell 55 and partially enter ing the coiler. Each coiler is held against upward displacement by means of "a set-screw" 58, passing through across-piece59ofthe machine and bearing against the top surface of the coiler-shell. I

To extend the coils as maybe desired or re quired as they emerge form the coilers, I provide a tension device, which-acts upon the coils as a resistance by destroyin the regularity of the spiral path to be taken b h coils after they leave the coilers; The purpose of thus extending the coils is to provide for a uniform pitch for. two companion wires, so that they will keep close together and run together in harmony. To this end I employ a short cylinder 60, (as detailed in Fig. 22

' groove 61, which is c'onsiderablywidened or enlarged at its moutl162, which is placed ,adjacent the rearward end of thecoiler proper. This'teiision-cylinder is adapted to enter the rearward end of thecoiler-shell and to cooperate with the coiler for the purposes named.

In one position of the tension cylinder ,60 its spiral groove forms a perfect c ntinuation of the spiral groove on the coiler, with the re sult that the coil as produced and to' be run into its weaving-channel corresponds in diameter and pitch to the grooves of the coiler and to its diameter. Howeverpthis tension-- cylinder is rotarily adjustable for. the purpose] of varying the pitch of the coils after leaving thefcoiler, and, as will be observed from an eX- amination ofFigs 13 and 22 of the'drawin s,

a rotary movement o'f'the tension-cylinder,

will break the uniformity orcontinuity' of the'spira'l by causing the wire to press with some force against one side of the mouth. or

enlar ed end of the groove ;6'1 in the tension cylin er and thereby flatten or extend the coils accordingto the amount of this rotary adjustment. I. For the purpose ofrotarily adjusting the tension-cylinder as described suitable means Tareemployed, and in the. present instance (see Figs. 1, 12, and 21) I provide the reduced end of each of such cylinders'with. an. up-

wardly-projecting pin 63, whoseupper- 'end' passesloosely through an opening in atrans- Iversely-adjustable bracket 64, slidable in a transverse groove in the cross-piece 59..

shown inFigs. 13 'and 21, .tlieseadjustable brackets are all dovetailed in said groove, and

byoperatinganyparticularone of tl ethumbnuts It will .be understood that it is preeach of them adapted tobe adjusted or shifted independently and transversely by means of a thumbf-nut 65, screwing upon. the

transverse screw-rod Q6, having bearings at its ends in said crossfpiecaFigsai 1," 13, 21.

Each nut is arrangedto bear against apro j ectionon its bracket, with the result that any v piece 73 of thereciprocating frame orhead.

oneof the "brackets may be shifted laterally ferred that the tenSiQH-cyIindersshaH have separate and independent adjustment and that consequentlythere are as many of the brackets and thumb-nuts as there are coilers andtension-cylinders. j

The wires as coiled by two' companion coilers are fed" along two channels or grooves 67,

formed on the-top surface of apl'ate 68 and converging at the forward edges thereof.

This plate, which ispreferably of non-con,- ducting material, such asa fiber, which is a non-conductor of electricity, extends trans-' versely of the machine, as seen in Fig. 1, and isof course provided with as many of said channels'as there are coilers, in the present instance having eight of such channels arranged in four pairs, inasmuch as four gangs of coiling and weaving devices for producing at the ends of the converging channels or grooves 67, and the same are then threaded through a knife-block 69, a series of which is provided in the present machine, one for each pair of coilers, Fig. 30. Each knife or cutter-block has a forward cylindrical portion and a reduced rearward portion which is cut down through a diameter to present a fiat horizontal cuttimt-surface over which the knifel70 passes. Ks seen in Fig. 13, the periphery or outer surface of the knife-block isspirally grooved fora portion of its extent in order to receive the pair of wires which pass together thereto from the coilers, and in order to forman opening through which such pair of wires shall emerge on the cutting-surface of the knife-block I surround the lower half of the knife-block, or at least the rearward portion thereof, with a semicircular band 71 ,whereby the opening 7 2 is provided forthe wires, as indicated-in. Fig. 28. a

The series of knife-blocks is secured in fixed positionin suitable manner, and in the present instance such blocks pass through openings in a cross-piece 73, and they are held or secured thereto by means of the set-screws 74, all as clearly-indicated in Figs. 25, '27,

and30. 1

Each knife-block is provided with a knife 70, which is moved at the proper predetermined time, with the result that the coiled wires are cutoff after a certain length thereof'has been fed'or run through the opening 72 to the weaving devices. In the present in stance the knives, which are flat plates pre :se'nting abutting, edge or corner to theknifeblocks, are secured in suitable manner to a transverse bar 75, arranged to slide in grooves formed in the upper portion of the cross (See Figs. 1, 13, 27, 28, and 30.) The knifebar is operatively connected with a trans-, verse plate 76,. adapted to slide transversely 'of the machine and to be'operated through connections with the'power or driving 1nech-' anism,-. as hereinafter explained. As indicated in Figs. 25, 26, and 27, this plate 76 has its bearing in the lower portion of the crosspiece 73 and the same is designed not only to operate the cutter-bar,,but also to operate a back-feed arm, as will-behereinafter described. The operating connection between the cutter- -bar and the actuating-plate 76 consists in the present instance, Fig. 25, of a lever 77, pivoted at its upper end to the cross-piece 73 and connected with one end of the cutter-bar by means of a link 78. The lower end of the lever is slotted in order to receive a pin 79. The object ofthe slot and of the connection is to enable. the feed-arm to be operated in advance of the cutter-barin other words to cause the triggers or. feed-arms to be first moved and the cutter-bar to be moved only near the last movement of the actuatinglate 76. As shown more particularly in Fig. 1, the left-hand end of the sliding plate is connected by a rod 80 with the end of an.

actuating-lever 81, pivoted on one of the side frames orbeams of the machine. The other'end of this actuating-lever is connected with a sliding or reciprocating rod 82, extending transversely of the machine and operated by power mechanism, as hereinafter first-described strand and to take the same On. .thefront side of this actuatingplate and.

position.- y

In the present instance, and referring more particularly to Figs. 25 to 31, the feed-arm is a pivoted lever or trigger 83, having a pe'culiar movement in order to enable it to accomplish the purposes described. This-arm or trigger is secured at its lower end to a transverse rock-shaft 84, which is' common toall of the arms or triggers employed in the (present gang-machine. This rock-shaft is,

supported at the rearward ends of the links 85, which are secured to a transverse shaft 86 suitably-journaled at its ends in the machine- .frame. The u per end of the arm or trig er voperatesin an projects slightly above a slot or opening 87, extending in a transverse bed- ,plate 88. or triggers in a normally forward position and to take up lost motion as indicated in Fig. 27,

I- ,employ suitable tension mechanism, suchas flat springsSQ, secured at their lower ends to a fixed part of the machine and bearing at their up er ends against the rearward side 0f,"

The other end of this lever 92is provided with a stud 93, wlnchi'sreceived and operated by a cain' slot or. opening 04 in the body of the actuat ing-plate 76, as clearly indicated inFig. 26.

The mechanism just described is employed for the purpose of giving the feed armor trigger 83 the proper vertical movements; but in order to provide for the forward and rearward movement of such arm I employ suitable mechanism for automatically sliding the plate 90, whose ends are movable in guides 100 in the machine-frame, as indicated in Figs. 25 and 27. this reciprocation is brought about by connection with the actuating-plate 76 by suitable connections, as follows: The plate iso'peratively connected withthe upper ends of arms 101, which are secured to a'rock-shaft 102. From this rock shaft projects forwardly an arm 103, whose extreme forward end is formed as pin 104, received and operated by a cam-slot 105 at one end of the ac- In the present instance tuating-plate 76. It will be observed that a slight transverse-movement of this actuatinglate will move the cam-pin 104 in a vertica plane, as indicated by the dotted lines in Fig. 28, whereupon the shaft 102 will be rocked and the plate or strip90 be thereby reciprocated forwardly and backwardly on' its pivots. Inasmuchas the plate 90 is operatively connected with the arms or triggers,

forwardly and backward y.

The different mechanisms described in connection-with each back-feed arm or trigger .combine to give the peculiar movement reuired-of the latter in order to act upon the orward end of the cut-off strand or set of' wires, and in Fig. 31 I have illustrated by dotted lines the course or path of movement of the extreme u 'per end of each-trigger in each of its cycle 0 movements, from which it will be seen that the first movement downwardly and then upwardly in a semicircle until it engages back of the first coil of the strand adjacent the cutter, whereu on at the next and forw'ard'movement of t e trigger" the latter will be corres ondingly actuated the extreme forward end of the wire-will be drawn forwardly of. the opening 72 in the knife-block.

J The cycle of operation of the .parts illustrated in Figs. 25 to,31 is as follows: ,Assuming that the wires have just been run through the coilers: and through the knifernechanisrn to the proper extent, the lever 81 is actuated, 12o' with the result that the plate 76 is shifted toward the right, Fig. 25, whereupon the stud 93 of the lever 92, which is normally held in the position indicated in Fig. 26; by the tension of the s ring 106'acting on the rocke shaft 84, will e contacted by the stop-finger 96 and Will-be forced downwardly-by the curved contact face or-surface' thereof, with the result that the lever92 will be rocked and such rocking movement mmmunicated to .the rock-shaft 84 and feed-arm 8 3, which parts will now assume the position indicated in dotted lines in Fig.'27. When the actuating-plate 76 is moved to the right, as described, the cam-pin 104 will ride upwardly in its cam-slot 105, with the result that the plate or strip 90, to which the trigger is also connected, will be permitted to move rearw.ardlythat is, to the left in Figs. 27 and 28.until the parts assume the relative positionshown by the dotted lines -in Fig. 2-8. Toward the end of the stroke of the actuating-plate 76 the knife mechanism will be actuated, inasmuch asby this time the stud 'or pinj7 9 Willhave traversed the slot in the lever 77 and have moved its lower end to the right,

Fig. 25, thereby moving the cutter-bar in the same direction and severing the strands or set of wires. Upon the return movement of the actuating-plate 76 the knives will be restored to normal position, and the feed-arm or trigger, which has already engaged behind the first 'coil of the severed strand, as indicated in Fig. 30, will move forwardly and draw the ends'of such strand forwardly and awayfrom the opening 72 in the cutter-block, so that the next strand orv set of wires as they emerge from the knife mechanism. will be properly run together with the first strand as a cord. In-this return movement of the actuating-plate 75 the stud 93'ofthe lever 92 will not be aifectedby t he'stop-finger, which will flip by such stud as such actuating-plate returns to said normal position. In this connection it will be understood that the feedarm or trigger, although continuously operating, is effective only when a cord is to be run, at which time the coil is not raised by the weaving-devices, but left inthe path of movement of such trigger; At other timesthat is, when a'cord is not to be run-the coil or wire is raised by the weaving devices out of reach of the fed-arrnortrigger.

" For the purpose of brin'gingthe ends of the strands or sets ofwires to a proper position at their forward ends, so that the wires may properly interweave, I provide for moving or reciprocating the entire head 4, which is so mounted asto-have a slight reciprocation'on the main end frame 1, this reciprocation being substantially one-half-the pitch of the 0011 being run, so that-the upper helix of the 7 running coil will interweave with the; lower helix of the preceding coil. In thepres'ent instance and referring more particularly to Figs. 13 and 14 the reciprocating head lis mounted to slide upon said mainframe 1 and is operatively connected with the power or drive mechanism in suitable; manner. As shown this is accomplished by means of a transverse shaft .107, journaled in the mainframe and providedwith similar pinions 108, arranged "to mesh. with horizontal racks 109 on each side of the machine. The racks are carried by the reciprocating head, one end of the racks being connected with the lower end of. depending pins or bolts 1.10 and the other ends being mounted to slide in openings in the other the entire reciprocating head is correspondingly moved. Asindicated in Fig. 4,

the rock-shaft 107 is-provided with a crank.

01' cranked. end 111, operatively connected,

by means of a rod 112, with another rockshaft 113, extending transversely ofuthe machine and actuated by the power or driving mechanism in a manner hereinafter explained. It will be understood that this reciprocating head carries all of the operating parts connected with the coiling and cutting oif of'the wirc ,-and it will also be understood that the reciprocations of such head are properly timed in order to cooperate with the movements of theweaving devices.

. From the foregoing. description it is obvi- .ous that the head will so present a running coil or wire that the same will properly interweave with the preceding wire or OOll.

After ,the wires have been coiled. and

passed throughthe cutting mechanism they are delivered to the weaving devices or mechamsm, where they are'woven or lnterlocked in order to form a complete coiled fabric.

The weaving mechanism is arranged in advance of the coiler and knife mechanism and in alinement therewith. As shown in the drawings, particularly in Figs. 1, 4, 5, 13, 18, 19, and 20, such weavingmechanism con sists of aweaving-channel, with which 00- operates a series of movable elements adapted to act upon the coiled wires in-order to bring about the desired weavingthereof. As shown, the weaving-channel is composed of two longitudinal strips or plates 11-1 and 115, ext-ending parallel to each other and having outwardly-directed flanges at their upper ends. These plates are lined on their inner adjacentfaces with strips 116 of brass orthe like, Figs. 18 to 21, in order to prevent magnetizationby electromagnet 117, occupying the lower portion of the channel and constituting, in effect,- the bottom of the channel. As indicated in Figs. 13 and.18 to 20, the electromagnet consists of a long field-frame extending from end-to end --of the channel and having a Winding which is electrically connected with a suitable source of supply of electricity and also connected with an auto matic circuit-breaker, whereby the magnet may be energized and denergized at the proper time in the cycle of operation of the machine, as will be hereinafter explained. This magnet is thus provided with a pole 118 of considerable length, inasmuch as it extends substantially the entire length of the weaving channel. sented to the lowermost coil of wire and when energized acts to clamp such coil with- This pole is always pre-
