' Previous to this-invention moquette or Aitmiiister carpets had -been woven `in several ways- I Accordin g-to one system of manu facturet-he tufting material in short lengths 'was secured injt'rames, one corresponding with each 'row'of tuftingjmateriai in the fabric.- These'ti'ames lwere manipulated by hand so as to introduce 2 5 the lower end-s ofthe material by a `downward 'movementbetween the arp-threads, the oper# ation 'being facilitated by guides for the spool-A lframe." The material was secured by, a-'shoot of l filling or weft-thread introduced by means ot' 3o a shuttle. The lower ends ofthe material were then turned upward by means of abrush operated by hand, and a second shoot of 'filling was introduced. `In this operation tlie-tufting material was introduced from above] the position ofthe warp-threads. The work was, however, done by hand,- and the operation was a "slow one.

material was -held in spool-.franies extending 40- crosswise ofthe fabric and iitted with needles for holding the ends ot the material. A series of these spools, suilieient in number to' produce thc design, was carried on a large revolving drum above the position of the' warp-threads. Above the warp-threauls, and in the vicinity of the breast-beam, there were a pair ot' nipperbars extending crosswise of the warp and ca.- pablo of opening and closing, as well as ot' be-A ing rocked downward to' and upward from the warpfthreads. Each spool'in succession was lowereduntil the ends of theftufiing material werewvitliin the space between the nipperfbars,

which were closed upon the said ends. The

n ipper-'bars were then rockeddow n to the Warp, and the spool was depressed tro-insert the needles between the warps.' A shoot of. weft' Athread was passed through theloopsoftufting material between the nipper-bars and the needles, after which the spoolframe was raised and the tui'tin'g material was cut'by means of' reciprocating knives. This mode ofoperation'is ob.

jeetje;lable becauseof theconl pon n d more ment;

required oi" the nipper-bars -and the diiiienlty oiinsertingxthe weft-thread through the loops of tufting material; hence this system has not. come into'use. y

' According to another method the tufting fmaterial was held on spools extending crosswise of thefabrie in thelooi'n, and a series of these spoo1s,.of suiiicient numberto produce the design, was carried by chains above the positionof the Warplthreads. -Eachsl'ioo'l was in successionbrought ,near the warp-t11reads,' and while there a series of nippers(one for each tut't) was moved upward from beneath the warptlireads so as .to pass 'between them The nippers were opened as they rose, were movetltoward the breastlbcam so as to rece re the tufting material between their'jaws, were closed Aupon the tuftingmaterial, were caused to descend with i-tso as to pull it downwardbencath the warp-threads, were'caused 'to move laterally,

and were causedwto'leasceud at the sides of the, warp-threads,opposite'those at which the nippers deseended,'so.as to place the ends of the tufting material at theupper sides of' the. fah- 'lhe Inippers were thenv opened to'release the tu'ting .material and were drawn downward so as to be out of the way ofthe instrument (shuttle or weft-carrier) which introduced the weft-thread or filling.' This -mode of-operation is objectionable because of the 'multiplicg ity ot" operations performed and-because the tut'ting material is secured by the warpthreads `instead -ot' by the weft or filling.

terial is carried upon spools confinedin an endless series, which is introduced into the loom beneath the warp-threads, so that each spool can be brought in succession beneath thelfell or cloth=making line. Each spoolis fitted with as many eyefpointed needles or guides as there are tufts in a row across thefabric. lEach spool in succession is raisedtoin troducethe tufting material upward between the warp-threads, and is lowered to withdraw the needles,`leaving the upper ends of the-tufting materialabove the warp-threads, after` which filling is int-rod uced. Then the spool audits needles are raised a second time, thereby introducing loops ofthe tnf't` ing material between the warp-thread-sTand'awire carrying a knife at its point i's introduced i through these loops of' tnfting'material. Subsequently thev spoolis lowered a second time, and theutnfting material in the fabric is eut loose from the spool by withdrawingthc wire, .so thatits knife end cuts the material. Accordi ing to ,this mode the tuf'ting material is secured by the weft-thread 'or filling;4 but the system is objectionable because ofthe introduction of the spoolsinto the -loom 'beneath the warpf threads, where the spools occupy space that is desirable for the mechanism of the, loom ;f also,

because itrequires the manipulation of' the cuttingwir e and because it also requires a Inunber of operations not above mentioned, which,

with t-hose mentioned, occupy much time forthe production ot' cach rowvoftuf'ts; hence the work, although performed by power7 proceeds slowly.

The principal object of the invention .whicht constitutes'the subject of this patent is' to enable moquette carpetto be woven by machinery operating to 'presentthe spoolsof tufring maY teral automatically at the upper side of the warpthread's,to introduce theends ofthe tuftin gvmate'rial by adownward movementbetween the warp-threadm'and to turn them directly upward around a weft-thread., so that the tufts are secured upon thcweft-thread 'or fillinf..

This mode of operation 4substitutes .automaticv mechanism-for the hand-labor required for thel hand-system of weavin g above referred to, and greatly increases also gets rid in one of the before-mentioned systems ot' power-weaving, and of the turning of the tufts around the warplthreads performed in that mode. It gets rid ofthe uselof the wire einployedin the other system of power-weaving,L and it also obyiates the objections incident to the presentationof the spools of tufting materialat the 'under side of the warp-threads, and it leaves the space beneath the warp free of spools, so that said space may be advantageously used for other mechanism ot' the loom.

The invention consists of sundry combinations of mechanical devices, whichare set forth in detail at the closcof this specification.

In order that the invention may be fully understood, panying drawings, and will proceed to describe, the principal parts of a loom embodying our thc speedof production. It' of the many movements required we have represented in the accom# invention in the best form at present known to us, with the understanding that the construction and operation of the mechanical devices may be varied 4as circumstances or the views of different constructors or users render expedient.l

The mechanism of the said loom performs the following operations, viz: The tllingor weft thread is supplied at both sides of. the loom, and thefilling from one side is drawn through the shed by the same implement which hauds-throu'ghthe filling` from the opposite side. Filling-ot' twogrades of fineness is employed, and the finer and .coarser fillings are selected automatically at both sides of' the loom, according tothe order inwhich they are .to be interwoven with the warp-threads. The

tufting material is carried upon spools, cach mounted ina spool-frame, and each having the assortment ot'. colored yarns upon itrequired for a particular one of.l the successive rows of tufts of which the design is formed. Each spool-frame isprovided willi a row of' tubes i for introducing the ends of the' tufting material intothe shed'. VThe series ot' spool-frames carried bychains, which are moved to present the spool-frames in succession to arms and their appurtenances, which take each spoolframe iir'its order-from the earrying-chains7 move it to the warp-threads, with the tuftingtubes in lhorizontal positions, or thereabout,

rock thespool-framcs so as tov carry the endsof lthe tutting-yarns down through the warp-- threads,V raise the spooland spool-frame suicientlyto permit the tut'ting varns to be cut at the proper distance from the fabric to leave therein tufts-ot' the required length, and finally restore the spool-frame and its appurtenances to the carrying-chains.` 'The ends of the tufting material introduced beneath the warp! threads Aare turned upward by" means of a comb', and are. secured by the interxlention of the filling. rial. is effected by the joint opera tion of a fixed blade extended acrossthe position ofthe fab- -ricin the loomr and a traveling circular blade,

which is moved to and fro crosswise ot' the loom. Y

In order that the above operations may be effected in weaving, the loom must, of' course,

be provided with means for holding the warplth`reads,f`or opening and closing the sheds, for

beating up the filling, and for the other in cidental operations required to weave moquette goods.l

loom de-` IOS tached from the residue, and denoted by the saine letters ot' ref'erence as the saine parts in the other figures.

The various moving parts otl thel loom are connected with a strong loom-frame, A, at the front ot' which is the breast-beam'B and clothroll C, while the warp-beams I) D and the rockshaf'ts 1) 1)' ot' the whip-rolls are supported at its rear. rlhe whiprolls are not shown, as they may be constructed and supported in the usual manner. l

The heddles 'for f'orining' the sheds are constructed in the usual manner and are supported in frames E, which are arranged to operate in the usual manner, they beingl moved by. means of' ievolviiig cams ll ll' -E E. with which the heddle-f'raines are connected by means of' the rods c, the levers El, rods c and theti'eailles E3, each of" these last being fitted with a fi'ictioii-wlieel that runs in the groove ot' its rcspcctivc cani. The f'ulcruin-stud ot' the lieddlelevers lil" is supported by an upward extension ofthe main `frame A, which also supports the lower shaft, lli, of' thc carrying-chains ot' the spools ll of' the tut'tiug material. rlhe lieddlecams E are secured to a camshaft, (i, which 'is constructed to revolve in boxes connected withthe main f'rame, and is driven f'rom the driving-shalt l through the intervention ot' the cog-wheels (l2 .(l. The driving-shaltl is provided with belt-pulleys in the usu'al manner, and tlieenstoinary appliances may be employed to stop the loom by transferring the belt f'roin the fast pulley to the loose pulley upon driving-shalt.

The filling or weft threads, when introduced as hereinafter described. are beaten up by means of'a vibrating lay, F, which is supported byarms l1" F', projecting f'roin a rock-shaft, F2. This lay is forced towar'd the breast-beam t'or the purpose ot' beatingl up the filling by means ot'a caiii,1", which is secured to the cani-shalt Gr, and is caused to operate upon thelay through the intervention ot the rock-shaft F, the arm F?, and its f'rictioii-wlieelf, which bears upon the cani F, the arms F, which project from the rock-shaft, and the links F7, which connect rthe ends ofthe arms F with the ears at the y i 4hence thc lay-cani 6o.

back of the lay.

The parts ot tlieiooni vrei'irescnted in the accompanying drawings are soarrangedl as to insert the tuf'tin'g material at every fourth beat ot' the lay, and asthc filling or wef't inserted after the tut'ting materialr is finer than that used at other times, a single beat ofthe lay is sufficient to drive. up suchfiie t'illine. vFor driving up the coarser filling it has been found expedient to impart to the lay a double beat; l?" is constructed with three double-headed protuberances, fj" f'f'or iinparting the three double beats to the lay, and

with one `singlc-headed protuberauce, f2, for

the single beat following the iiiscrtiii ot' the finer filling. [l the lay were constructed in the usual manner, with an upper horizontal bar above the reed, it would occupy space which the hence. the lay is constructed without any npper bar, butl with a clamp-bar, f, at its front side, between which bar and the t'ace of the iay can be used profitably for 'other purposes;

a series of metal loops or pins,f1, are clamped to f'orui the dents ofthe reed. The cani F moves the lay forward, as required, to beat up the llliiig, and the backward movements of f the lay are effected b;v a spring, F9, operating upon an ai'ni, F, ofthe lay rock-shaft 1?5. Y

rilhe filling' to be used iscwoundnpon bol)-` l Y I bins or cops, which are set` at .opposite sides ot' the loom in convenient'positions to permit the filling to pass to the devices which act upon it, and it is passed across the loom throughthev open sh'eil by means of' reciprocating wef'tt cari-ier l, which is moved to and f'ro at the proper times by means ot' the. cam l (on the cam-shaft (l) and the spring 12, which acts antagonistic-.illy to the cam. The cam is caused to operate upon the weft-carrier through the intervention ol' the l'iietioii-wlieel l, the lever l, thel rod l5, the elbow-lever 1, the' linkl", and theI slide-block l, to which the shank of the wett-carrier is secured. The spring 12 is connected', in this example, with the lever l,

and therefore operates. through the int-ervention ol' that lever and its connections with-the weft-carrier. The weft carrier is guided in its movements by means of' the guide-bar l, upon which its slide-block if* is constructed to move,

and by the guide il through which the stem ofthe wett-carrier moves. Y

i.\ceording to one part of the invention two loops of' wef't or tilliug (one the loom) are passed througheach shed that is opened, so that both selvages are made secure, although the filling is introduced in the forin of" a loop. lnorder that the saine weft-- carrier may pass the filling f'r'oin opposite sides ot'the loom, its head li' is bot li f'orked and hooked,

asseen more )nirticularly at Figs. 6, 7, S. The crotch ofl the fork fi engages in the loop ofthe filling, which is at the saine side of' the loom as the wef'tcarrier, and pushes that loop through the shed, and the bill of' the hook i* IOO from each side. ol'

engages with the filling at the opposite side ot' the loom, and pulls a loop ofthat filling back throi-igh the shed when the'wett-carrier is retrogi'aded.

by the weft-carrier by two,wett-holders, J J", on e at each side of` 'the loom, and the welllthreads or filling extending t'ioni the selvages to the bobbiiis ot' filling at the sidcsof' the loom are held by these.weft-holders iny the rear of thc path ot movement of the head ot' the weftcarrier. In thisloom two grades of' filling (one coarse and one fine),are used,the\fiue filling being used at'ter the insertion of' the tufting material, so as to fasten it, and the coarse filling at other times, 1n order that the fine and coarse fillings may be presented to' the weftcarrier in proper order the wett-holder J, at the right-hand side ol' thc loom, is fitted with twoguides, jj, Fig. S, (one .for each grade of tillthrough which the head of the han d io 22, secured to the cam-shaft G,

- weft-holders J J ing,) which, by preference, arel made in the form of eyes, and are separatedby a space weft-carrier can and the weft-.holder J', at the leftside of the loom, is fitted with two guides, j j', Fig. 10, which, by preference, are made in the form of hooks. Moreover, these weft traverse,

1 holders are moved simultaneously upward and downward by the operation of a cani, J2, Fig. so as to place the proper eye-guide and hoolcgiiide inthe positions to hold the filling to the weft-carrier for introduction into the same shed at the proper times. rlhe cam J2 ope'rates upon the through the` intervention of the friction-wheel J 3, the vibrating lever J4, the rod J5, the arm J, and the rock-shaft J7, with which the shanks of the weft-holders J J are connected. The weft-thread or filling at the zo left-hand side of the loom is passed through stationary eye-guides j2 7"2, Figs. l and 5, before beingl introduced into the hook-guides of the weft-holder. l

rlhe operation of the said 'devices in the said 2 5 loom is as follows: The weft-guides are' moved upward and downward to positions above and below the line of travel of the longitudinal axis of the weft-carrier. Then they are in a middle position, between the extremes of th cir upward 3o and downward movements, neither weft-thread is in a position to lie-taken by the weft-carrier, butthe two weft-threads at each side of the v loom extend in 4straight lines from the correspending corners of the fell of the fabric to the 3 5 eyes and hooks of their respective guides, the

upper weft-thread at each side of the loom being then above the horizontal line of travel of the head ofthe weft-carrier, and the lower weftthread being then below. that line of travel.

4o When the upper weft-thread at the right-hand side of the looin is to be taken across the shed of warp-threads the weft-guides are depressed. by their earn before the weft-carrier begins to move, or at about that time. The effect of such 4 5 depression is to bend the upper weft-thread, ex-

tending between the fell and the weft-guide, downward across the shank of the hook fi?, Fi e. S, within the range of motion of the crotch i', so that when the weft-carrier `moves forward its u 5o crotch comes in contact with the bent weftthread and pushes it through the shed to the left-hand side of the loom. After the weft-carrier commences to inoveforward theweftguides are restored to their middle positions by the action of their cam J 2. When the lower left-hand weft-thread isj to be taken bythe return inovement of the weft-carrier the weft-guides are raised frointheir middle position after the weft carrier reaches its inost outward position and 6o before it commences to return, or tliereabout.

By this risc the lower left-hand weft-thread is bent upward between the corner of the fell and the appropriate lixed guide jl and across the shank of the hook fi?, and as the hook-guide J (whose rise produces this upward bend) oper- ,ates between theiline of travel of the weft-carrier and the fell of the fabric the weft-thread so bent is within the range of the hook i2 of the weft-carrier in its return movement, and is drawn by it through the shed. After the hook of the \\'eftcurrier has safely hand weft-thread thc weft-guides are restored to their middle positions. Then the lower ri glit-hand weft-thread or the upper left-hand weft-thread is to be taken the motions ofthe weft-guides from their middle positions are reseized the leftversed, the ri glit-liand weftguides being raised before the weft-carrier starts to cross the shed, or thereabout, and the left-hand weftguides being depressed before the return movement, or thereabout.

The construction of the reciprocating wei'tholder with two guides enables one weft-thread to be guided to the position for'ngageiuent with the wefticarrier, and the other weft-thread to be guided out of the position for engagemeiit by a single movement. of one ucd-holder, v

and is therefore advantageous.

In order that the loop of weft-thread or illing introduced by the \\eft-carrier while moving in one direction across the nshed may not move baek'with the said carrier when it moves in the opposite direction a spring weft-finger, c, Figs. l, 5, 55, and 1l, is provided at each end of the lay to enter and hold the end of the loop. The spring a-ppertaining to this weftii'iger permits it to yield crosswiseof the loom in the direction which the weft-carrier is travcling as the head of the weft-carrier passes by it, and then causes the weft-finger to move back and engage in the loop. When the lay retrogrades, after having beaten up the filling, the weft-fingers are withdrawn from the loops.

In order that the tu-fting material may be introduced into the fabric it is wound npoii the spools I1,of a length sufficient to hold the yarn required to form a row of tufts across the fab ric, the material for each tuft being wound on the' spool in a belt or zone. Each spool is fitted to tnrii upon journals, which are held .in a spoolframe, 1I', (represented more fully in Figs. 12 Y and 13,) and tl-ie longitudinal bar h of thisv spool-frame is fitted with as many short tubes or nozzles h' as there are tufts in a row across the fabric. When the spools are' prepared for use the ends of the tufting material are passed from the spool through the tubes, and are permitted to protrude suflieiently therefrom-say rIS one iiich-to be engaged in the warp of the fabi ric. As many spools are used as `there are to be rows of tufts in the pattern before the same is repeated. In order that these spools may be held and presen ted iii succession tothe mechanism which takes them and introduces the ends of the tufting-yarns between the warpthreads two parallel endless chains, Ilz, are provided, Aand arc constructed to hold the series of spools above the position ofthe warp-threads extending through the dents of the lay F, and over the breast-beam B, so that the tiiftin g inaterial may be iiitrodnced into the fabric from above the positions of the warp-threads. These the chains are. supported upon a pair of sprocket-wheels, l 1"", l`ig.1p5, secured to a second shaft, ll", which is atl the requisite. distance from the tirst sprocketwheel shaft llt to hold the chains extended.

In order that each spool-frame ma)v be readily connected with and disconnected from the carrying-chains, each chain is formed ot' single links hfi and double links h4 in alternate suescssion, and the ends h, Figs. 12 and 13, of the spool-frames are titted to engage in the slots between the members ofthe double links. Moreover, each end of each spool-frame is provided with a spring-catch, h, Figs. 12 and'l, whose inclined head, when l'ircsscd against the outer edge ot' the inner member of the double link, yields, passes by the inner side of the link, and engages with its inner edge, so as vto hold thespool-l'rame to the chain. The Shanks of these spring-catches h are passed through slots in the ends of the spool-frames to their outer sides, where the)V arc in convenient positions to be forced inward for the purpose of disengaging the heads of the catches from the chains, and thereby releasing the spool-frames. Each sptml-frame is titted with a spring-lnake, la", which bears upon the rim of one of. the spool-heads, and prevents the spool from turniug,'unless the tuftinginaterial is drawn from it.

ln order that the spools may be transferred in succession to thc'place where the tufts are to be introduced, the lower,` sprocketwheel shaft, 11, is turned interinittingl v,rso as to4 place each spool-frame in succession at its lowest position, and the chains then remain at rest, while the spool-frame is taken from them,

is transferred to the place of weaving, and then restored to the chains by the spool-transferring mechanism Thcehains are then moved to bring the .next succeeding spool-frame into its lowest position.' v

The mechanism for turning the lower sprock- 'et-wheel shaft I-l intcrmttingly'may consist ol' a. ratchet-wheel securedto the sprocketwheel shaft,of a hook to operateon the ratchetteeth in succession, so as to pull them round, and of aeam and treadlc to move that l|oo'k,: the cam being secured to the cam-shaft G. A

pawl also may be provided to prevent retrograde movement when thehookis retrograd- As the construction of such mechanism.

in". is well understood by loom-builders it is not represented in the drawings. I

In lorder that the spool-frames maybe taken from the earryingchains, two transferringf arms, K K, are provided, each bein g connected with an arm,K', projecting from a rock-shaft,- K2. The transferrim.;arms, as represented in detail in Figs. 16, 17, 18, and 10, nrc pivoled 'to tlierock-shut't arma K', nothlt the outer ends of the former may he moved horizontally toward and from each other, and their rear ends are inserted into guide-slots at the hubs of the rock-shaft arms K', so that the transferring-arms are prevented t'rom wabbling relatively to the rock-shaft arms K'Ain vertical directions. vrlhe transferring-arrns are caused to vibrate at the time when the spoolt'rame is to be taken from the carrying-chains and transferred by adownward movement toits position for delivering tut'tin g material to the fabric being woven, and when the spool-frame is to be returned tothe carrying-chains, by means of a cam, K3, (see Fig. 16,) secured to the cam shaft G. This cam is constructed to operate upon the rock-shaft; K2 of the transterriug-arms through the intervention ot' the friction-wheel K4, lever K5, and rod K, kthis Arod being counected' at itsvupper end with one of the rockshaft arms K. The cam raises the transferring-arms and permits them to descend.

In orderthat the transferrin g-arms maygrasp and hold the spool-frame, theonterend ofeaeh transt'errin g-arm is fitted with a cluteh,'K7, having three horns orprojeetions, k 7.' k', (see Figs. 1G and 17,) the tirst two, 7.' 7:, being separated by a space suticient to admit the'end of the spool-frame easily between them. The third horn, k', is arranged so as to pass beneath the cud ofthe spool-frames. All these horns should be made daring at their inner sides, so as to en able them to be readily applied to the ends of the spool-frames. In order that these clutches IOO clutchcsaremoved outward to release the spoolframe, and 4are permitted. to move inward to grasp it atv the proper times in the'opcration of theloom, b v meansof a cam, K10, secured tothe cam-shaft Gr. V(See Fig. 1S.) This clutch-cam f operates upon the rear end of one ofthe vibrat- A ing-arms K, through the intervention of the friction-wheel K",lever K12, rod K', and wedge k, the wedge entering between the end of the vibrating arm and a guide, k?, secured to the hub of thc-rock-shaft arm K. The cam K1" moves the wedge 1an-in one direction, and permits it to be moved in the reverse direction by asprin g, KH. 'lhemotion isiinparted from one of the vibrating arms to the other bymcans of the rods k* and intermediate lever, K9.

`Accord-ing to one part of the invention the. spool-frames are presented to the warps with their-,tubes in horizontal positions,and arethen rocked so as to turn the ends ot' the tif tin g inaterial down between, the warp-threads'.

In order that the spool-frames may be so presented audrocked euch clutch K7 is combined with the end of itsrespcctive transferring-arm and that these are turned by a pivot, which permits it tobc rocked, and in order .that the clutches may be rocked at proper t-iiiies, as required in ythe operation ot' the loom, a cam, L, Figs. 5 and 16, is secured to the cani-shaft G, and is connected with the clutches through the intervention vot' the friction-wheel L', the arm L", thc rod L5, the clutch rock-shaft L3, and its arms L4 L, andthe rods these last being connected, by. pivots l"1 with the clutches. y The clutch-cani L rocks theA clutches in one direction, and permits them to be rocked in the reverse direction by a-spring, L", which is connected with the arm L. The rocking-cam L is so formed and. set relatively to the transfer-cani K (which moves the transerring-arinsKfroin and to the cairyiiig-cliains) that when the spool-frame is brought to the warps its tubes are horizontal, orthereabout, downward and forward through thewairps by the rocking of the spool-frame by the action el' the rocking-cani on the clutches. f

In practice it is convenient to take the spoolfranie from the carrying-chains when the spoolframeis hang/ing vertically,or thereabout, from the lowest link ot' the chains; hence the rocking-cani L is so t'orined as to rock the clutches K7' during the downward movement Aot the transferring-arms, and to thereby place lthe tubes in horizontal positions by, the time the spool-frame reaches the warp-threads. At this point the spool-frame is rocked into a vertical Iposition,thereby inserting the threads between the warps. After the ends of the tnt'tingniaterial have been introduced between the warpthreads by the rocking of the spool-frame, as above described, a shot of tiiic tilling is introduced into the shed to secure or fasten the ends ot' the tul'ting material. Thc'n the ends are tui-ned backward,or away from the breastbeam, and upward previous to the introduc-` tion ofthe next shot ot' coarse filling. The turning o1' the ends of ther tufting material backward is ellected by a reciprocating comb,

M, Figs. 1%, 2, 20, which is constructed to reciprocate horizontally,or thereabout, between the breast-beaiii and the lay bt the loomand beiieathtliepositionot' the warp-threads. This comb is connected, by arms M', with the comb rock-shaft M2, and its movements are controlled by an internal cam,M3,`Figs. 5 and 20,secured to the cam-shaft G, the said cani having a laterally-projeetin g rim or ange, (represented in dotted lines at in, Fig. 20,) whose inner side operates on the friction-wheel M4 ot' the camlever Mi. The cam, Fig. 20, acts upon the comb through the interveiit-ionotthe frictionwheel M, the lever M5, the rod M, the rocksliaft M, and its arms MTM.y The cani, drawing the leverfltlfrforward, moves the rod M6 andthe lower cnd ot' the arni M7 forward, thereby rocking the rock-shaft M2 and moving the comb backwardin the loom. The cam l\1,also,I in irq-revolution,permits the comb to be moved forward in the loom by thc action of a spring, M,whichisconnected withthearmM". When slot moves upon Asition and to be pressed upward the comb moves backward `it is it should be pressed upward pressure, so that it may turn expedient that with a yielding the endsof the -tut'ting materialupward, and when the comb is moved forward itis expedient that it should be depressed, so that its tee'tli may clear the fabric. In order that the coiiibinay bc pressed upward, and also depressed, rigidly witht'he rock-shaft arms M,but is connected with them at its ends by pivots m, Fig.

it is not connected A 2, so that the comb-teeth may be depressed and raised by r0cl;i;ng tlic comb on these pivots lt, is convenient to effect the depression of the comboby the saine cam,yl\l3, which moves it backward, and to this end the comb-stock is connected, by an arm, m', lilik m2, and lever in, with the extended-.extremity 'm4 M, through the intervention ot' which the comb M is operated. y This rod ,M'has a slot in itfor thc pin of the arm M7,"so that when the rod MF is drawn back by the comb-cam M3 (for the purpose of depressing the comb) its the pin of the arm M" and docs not move the comb forward. The combcaiii is fitted with a.v supplementary grade or projection, mrFig. 20,to operate the rod M6 when the comb is to be depressed. The comb is pressed upward with a yielding pressure by means of a spring, m, which operates upon the comb-stock through the intervention ot the` This spring tends to v arm m', secured thereto. move the comb upward whenever it is permi-tted to do so by tlic comb-cani qnently, after the comb has been moved forward in theolooni, the turning of the cam per,- mits the comb to rise and resume its upper poby the spring v The stock of by a guard-plate, M9, over during its backward movement. the comb is covered which thefabric passes to the breast-bemin.

and the rear edge of the guard-plate acts as a stop to limit the forward movement of the comb. Y l

After the ends of the tut'ting material have` been `moved backward and turned upward by the operation of the comb, a shot of coarse 4filling is inserted bythe operation of the wet'tcarrier I. Then the spool-frame is raised sutieiently to permitthe tiifting material to be ent between the ends of the tubes and the fabric.I so as to .leave the row ot' tufts in the fabric and the tut'tng material protruding suiciently from the tubes to be in position for being iiiserted between the warp-threads the next time that saine spool-frame is brought nto use in producing the design. This partialraising ot' the spool-frame is effected by the action of the transfer-cam K3, which moves arms, and after such raising the transferringarnis and spool-frame reiiiaiu at rest, by reason of the form ot' the traiislercaiii,until the tufting material is cut.

The cuttingot the-tufting material is ellected, according to certain parts ot' the invention, by the action.osjdisk-cutter, N, Figs. 15S, 2, 3, 4, 21 and. 22.1; hi'elif is caused to reciprocate across the transferringv ot the rod M3; conse- IOL) ' Ythos the loom, an"il to turn on its central axis as it moves along. This disk-cutter operates in connection with a lixed blade, l), whichis, by preference, formed with a cutting-edge, so ns to cut aswell as support the tuiting material for the action ci.' the disk-cutter. The fdisk-clitter N is pivoted to a carriage, N', which is constructed to slide crosswise of the loom upon the two slide-bars Nz N2. The opposite ends of this carriage are connected, by with two pulleys, N N 4, secured to a shaft, N5, which is caused to turn alternately in opposite directions andat'proper times by sccuied to thecani-shaft G. This cutting-cani N is connected with the cutter-shalt N5.' through the intervention ot' the friction-wh eel n?, the lever N7, the cog-segment N, and the pinion NgThe carriage-cords pass over pulley-sheaves n*- 115 the loom, are wound in opposite directionsupon their respective pulleys NJN, and are secured thereto; hence the turning of the cutter-shaft in one direction by the cutter-cani lets out one cord and winds up the other, so as to move the disk-cutter in one direction across the loom,

, and the turning of the cutter-shaft `in the opposite direction reverses these movements and moves the cutter iu the opposite direction across the loom'. The disk-cutter is caused to turn upon its axis while it is moved crosswise of the loom, and is operating in combination with the tixed blade. .v

The mechanism which itis preferred to use forthe purpose of compelling the disk-cutter '35 to turn upon its axis or revolve is the .following: A cog-rack, fn, issecnred toene of the. bars N2, and an upright shaft, fn?, is constructed to turn in bearings in the cutter-carriage. The upper end ofl this upright Ashaft is -iitted with n, pipiom n, whose teeth' are engaged with .zof the racha, and the lower end of the saineshaft is fitted with a cog-wheel, ng, whose teeth nre'engaged with those of a second cogwheel, nl", which is connected rigidly with the disk-cutterN; hence, when the cutter carriage is moved -across the loom, its shaft n7 is coniu, and the revolving movel to the disk-cutter through upon the pinion nient is imparte ina-y be moved out of the way ot' the spoolfraiiie nt'theA time itis moved to the warp, and may be brought into the proper back sufiiciently for that purpose, the fixed the loom-frame as to have a reciprocntin g movement toward and from each other. For this purpose the. stock P. of the` fixed blade P is connected, by arms PF. with rock-shaft, P, and the slide-bars N2 of the disk cutter carriage are connected, by arms N19, with a second rockshaft, N, so that by rocking the. said rockcords n n',.

Two sets ofthese rock-shaftarms and links are used, (one set ateacli side of the loom,) in order that the entters may be held together while the disk-entter passing from one side of the fabric to the other during the cutting ofthe row of tufts. rlhe cutter-cani Q moves ,the cutters toward each other, and permits them to be moved apart by the operation of a spring, Q4.

The arm Q2, wliicli'.inipa1ts motion from the cam Q to the first rock-shaft, P3, is madel adj ustable, so as to enable the cutters Ato be set to operate as required. ',Vhen', both cutters have cutting-edges, it was found ,expedientat the date'of lthe application for thel original patent to so arrange the -cutters relatively to each other l under that of vthe fixed cutter. i

The cutter-cnm NG, for traversing the circular cutter N,is of such foi-ni tha-t the disk-cutter is moved crosswise to the left-hand side of the loom while thecutters aic separated, and is moved crosswise hack again for cutting while the cutters are held together by the action of the'cani Q. y i

After the tufts are cut loose from the spoolframe the latter the carrying-chains by the upward movement of the transferriiig-arms K by the action of the .transfer-cam K3. are drawn apart by the action ofthe cam Kl, so as to release the catches h6 of the spoolframe, and permit them to secure the spoolframe to the carrying-chains. I ofthe clutches is continued su tiiciently to cause them to stand clear of the spool-frames, nnd the clutches aie held thus separated until the carrying-chains have `been moved sutticiently rto remove the spoolvframc that was last used rfrom the range of movement of the clutches,

and to bring the next succeeding spool-frame of the series within that range, so that it iiiay be taken from the carryiiig-chnins by the transferriii g mechanism, as required in the operation ofthe loom.

In the weavingof tufted fabrics by the'looin, .parts of-whicli are represented in the accompanying drawings, it was deemed expedient to introduce the tnfting imiterial at evciv l'ourth shotI ot' the filling.
