IMPRQVEMEIII INl LOOMSFOR WEAVIG CARPET AND OTHER FIGURE!) FABRICS.

To all whom it ma i' concern:

Beit known that IERASTUS B. BIoELow, of Ciintonviile, in the cou nty of Worcester and State of Massachusetts, havefin'vented new and useful Improvements inLooms for Weaving Twoand Three Plied Kidderminster (Jar-v pets and other Fabrics; and I do hereby declaro that the following is a full, clear, and

which distinguishes them from all ther things ore known and of the manner ofrnafking, constructing, and using the same, reference making part of this specification, in which- Figure 1 is a perspective view of the entire loom with the jacquard arrangement; Fig. 2,- sn elevation of the right-hand end thereof, with the shuttle-boxes and the machinery for working the shuttles removed;` Fig. 3, a like,

of the loom below the jacquard and without the harness.

The .parts which are represented i'n sectional figures will be referred to in their ap,

The same letters' indicate like parts in all the figures.

The ilrst part of myinvention relates to the operation of the jacquard by its connection `with the power-loom ;and itconsists in depressing one trap-board, (or more,) while the other (or corresponding trapboard) is elevated, whereby the power required at each operation for elevating that portion of the harness and its sppendageswhich carries up the warps is balanced in whole or in part by the remaining and descending portion, thus equalizing the wer required to give the motions, and thereore admitting of more rapid working of the mechanism,for when the trap-boards are opcrsted separately at the time of lifting agreat strain comes upon the machinery of the loom, and hence the motions can neither be sov easy or so quick, and another and important advantage is the saving of one-half of the time required for working the trap-boards, for when they are worked separately one must havev operations are performed simultaneously.

The second part of my invention, which reto the location and operation of the jou rl'lais above the jacquard, whereby the knotted y and F the bottom fron of thetrap-boards on them scured.

The third part .of ,my invdn-tion, which re- "lates .to the working of the hards for changing the figures, consists in working the card-vV prism while the trap-boards are at rest by a cam or the equivalent thereof connected with theloom or receiving motion therefrom. i The fourth vpart of myinvention, which relates to the delivering or giving ont of the warps; consistsjn regulating the delivery or giving ont of the warps by the tdnsion of the warpswor chain' actingy ona vibrating miler ('or the equivalent thereof) intervening between the take-'up roller and the yarn-beam and combined with a regular fand positive motion for taking up the cloth as it is woven.A tol produce gures thereon which will match the irregularities of the weft or lining, being thereby taken up in the thickne'instead of the length 'of the cloth'.

The iifth partfof my invention, which ,xy lates to the shuttle-boxes, consists in the ployment of series of shuttle-boxes in sepa rate frames independent of the iaymnd by the side thereofnvhereby the weight of the shuttle-boxes and their appendages sremoved from the lay,A which adapts. 'it the'hetterto the quick movements quired i., z powerloom weaving with econo The last part of my in y,

e 'loom `when a change of colors is required, consists in combining the shipper-of the loorb (or the' equivalent thereof) employed for stopping the loom with the jacquard, whereby the loom wili'be stopped by thev operation of the. jacquard whenevera change of colors is required. l

'lhe 'cogge'd wheel N is affixed to the cam-shaft and takesinto the cogged wheel P, which is keyed to the .lathe-shaft Q. The relative sizes ot'thc cogged wheels N and I are as four of the latter to one of the formcrLthat is, the wheel .the loom.

The driving-pinion M may be ot' any size which will give the requisite power to drive The lathe-shaft Q revolves in the boxes R R and operates the lathein the following manner, viz: S 4S are the swords of the lay, which vibrate in theTT. The race-beam U and the top shell V support the reed W. X X are double or hollow cams keyed to the latheshaft' Q. The places of the grooves in these double or hollow cams X X are shown by the dotted lines in Fig. II. there are frictionrrollers, which are fitted to them, said rollersV revolving on studs which are firmly affixed to and project` from the outer sides of the swords S S. The rollers and the studs above named are concealed in the drawings by the cams X X; but such iixtures are well known, and from the description here given it is evident that when the shaft Q revolves said cams will give the lathe the required motion. The cam-shaft 0 revoives in boxes (see Fig. 4 and has aixed thereto the cams or wipers 1, c, d, e, f, and g. YIn the operation of the l'oom the cams or wipers b, c, d, e,f, and g act on their respective treadles h, 12,3', k, l, and m, which treadles are hung at onel end inthe treadlehangers n 1r. and guided in their vertical motion at the reverse ends by the treadle-guides 0 O. 'ihe particular oice'of said cams and treadles will be described in connection-with the parts of the loom which they actuate.

The first improvementto be noticed is the peculiar construction-and arrangement of vthejacquard machine, whereby one trap-board ismade to descend while the other rises, and

the weight of the harness on the descending.

trap-board is made to counteract .or'balance the weightl of the harness on the ascending trap-board, thereby equalizing the power required to drive the loom. l

This machine is described aiid represented in the drawings as arranged for two-ply carpets.

In Figs. I arid III, p p is the end frame ofi Within these grooves `:olve in the 'sliding bars a: nr, which 'have a. horizontal reciprocating motion through suitable guide-'stands y` 1/, boited to the frame p p.

zz are vibrating levers affixed to the fulcrum-shaft a', and are connected to the slid- ,ing bars :c a: by means of rollers working in slotsin their lower ends. on the stands b b and has the lever 'c' extending from it at right angles with the levers .z E.' The arm or lcvcr c is connected' to the tradlc 'i by means of the cord or rod d and is actuated by the cam c. The cam c acts on the treadle i and depresscs the lever c and carries out the card-prism or polygon w, and

when the cani c rclievesits action onl the ,treadlei the card-prism w is brought back again against thc needle-board by the action of a spiral spring encircling and acting uponv the shafta. l

f' is the snackY or latch to turn the cardprism w when it iscarriedA out by the levers .zz. The hammer, which secures the prism w in its proper position, is concealed in the drawings behind the bar but its constructio'n and action on the prism 'uf are the same as in other Jacquard machines. The needles are also arranged and worked in the same manner as in the machines in common use for hand weaving. The trap-boards gf and h' are perforated with holes inthe usual way, andare supported'by the guide-rodsi 'iand j'vj, said rods being guided by the guidestands k k', bolted'to the frame p 1. The guide-rods i and j' are .oennected vwith the vibrating levers l' m by the .bars n o', said `bars being connected to said guide-rods and levers at their respective ends by means of a joint-pin. i 'lhe vibrating levers l' l and m' mf are fastened to their respective fulcrum-y shafts pand q,wh ich turn in suitable bearings in the frame'pp and have thelevers rr" ands extending from them" opposite to the levers l 1'; and m m'. The journals t' u lu' w are placed at hthe top of the Jacquard machine and fastened to theirrespective rods "y z a", said guide-rods b'eing guided ythe guidefstands idk. The guide-rods z y z a are connected to the respective vibrating levers b, c' df', and e" by lueans'of the l connecting-bars f", g", h, and i7', said bars i turn .in suitablebea ngs in the frame p p 'Y and have extending from their sides opposite the vibrating levers b, c, d", and e thearms or levers n", o, p", and q".

Then at the'same time that the journal t and the trap-board g descend the journal w and trap-board h rise.V When the journal w and trap-board h' descend the journal u and trap-board g descend the jouroperstien, as before. W.

The card-prism or polygon w isp-operated by the cam'c while the trapkord qy 'and hA are at rest, eitherone or the other of said trapboa'rds being in a raised position. By working the card-prism rv in this way one of the trap; boards may descend while theother. rises without disturbing thev perfectvaetion of the machine. The knotfcordsz" z are suspended down through the trap-boards g h' and the needloeyes and conn t with the neck of the harness a a" in e ordinary way. The neck of the harness af" a' passes down from the knotcords z z" through the stationary harness-board b' to the mails, from which weights are suspended in the usual manner. The knot-cords and the harness aforesaid are represented in the drawingsby the redlines; but the mails and the weights are connected behind the reed W and the breast-beam B, and these being the same as those in common use it is not necessary to represent or describe them. a i

The second improvement to bc described is the peculiar construction and arrangement of the machinery employed todelivcr out the chain or warp and take up the finished cloth, which machinery-operates in such a manner as to give a uniform tension to thc,chain or 'warp during the process of weaving and ihfigure.

In Fig. 2,l cf" is the yarn-beam, which, for the convenience of having it of large size, is placed under the Hoor f in the story of the mill next below the loom and is supported 'lhe endless sci-cw or worm h is ailixcd to the vertical shaft 12' and takes into the cogged wheel j" on the yarn-beam e'. The vertical shaft i" is snpported by the stands c""and has affixed toits upper end the contrate ratchet-wheel Z. Above thc contrate ratchet-wheel 1" is the vibrating lever m, which -turns ou thc vertical shaft fi as its fulcrum. 'To onc 'end of the vibrating lcver m' the click- -n' is attached, which actnatcs thecontrate ratchetwheel Z', and the other end is connected to sliding-bar 0" slides in thc standards (im fj' and is encircled bythe spiral spring fr one cud of which rests against thc standard q and thek other end against the Istud or arm .q'". To the end or the im s",','proeensg .isattoward the loom, one end of the rod t' tached, the pther end of said rod being bent in a hooked form and working in a groove in the stud u', projecting from the sword of the lathe s. When the lathe approaches the. breast-beam to beat up the cloth, the rod t draws the sliding bar o' forward, and when the lathe returns the spiral spring r -fonces said vsliding bar o back until the arms" strikes against the stand `q"',' which deter# mines'the degree of motion of the sliding bar 0. The sliding bar omis connected to one end of the vibrating lever v' by the rod orf Y bar w'. To the other end of the vibrating lever v, theclick 1s attached, which ac't-y uates the contrate ratchet-wheel y'. AThe contrate ratchet-wheel y is,afxed to the vertical shaft z, which turns in the stands fixed to the upper end of the vertical shaft in bearings in he frame A A and is covered with emery'or otherwise rendered rough to increase the friction on its surface. The 4roller e, resting upon the roller d"", is covered with cloth and guided by bearings i'n the frame A A. The roller e" is weighted down uponthe roller dm', to prevent the cloth from sli ping between the'm, by means of the hooks jg j the levers 9" g", and springs or weights h hm 'lho vibrating or `tension roller z" may be of any convenient diameterand vibrates up and down in grooves in the frame A A.

j'j are hooks hanging in grooves on either end of the tension-roller 1 and conical with the spring km', which is adjusted'by' means of nutson the lower ends of the hooks j' jm and' gives a proper" tension to the war or chain.

l is the regulating-lever (shown by lthe l dotted lines in Fig. II) to'regulate the quantity of yarn delivered. out from the 'yarnbeam e and vibrates on the fulcrilm-stud mm. The regulating-lever 1" is connected at one end to the tension-roller of the bar nf and at the other end to the click n by means of the cord 0, so that when the tension-roller iwvis depressed it raises the click n from he ratchet-wheel l and cuts off its action t iereon, and when said roller is raised said click falls down and 'removes its action on the `ratchet-wheel1'. The yarn passes from the yarn-beam e\np through the floor f, over the girth' D,

through thc mails, andv through the reed IW,

over the roller C in the hreastbeam B, thence down around the tension-roller-W, up over the roller e, thence between the roller e"" and the roller r", and down through the floor f as shown by the red line in Fig. II.

The diamctcrynf the roller dm and th'e number of teeth in the cogged wheel c' and in the contrate ratchet-wheel y' tioned that the periphery of the roller 12".

13 by means are so propor- .roller d"must move oiie-fortieth of an inch every thread of filling introduced. It is ob- Yriphery of the roller d may be varied either y'", The cogged wheel i"onthe yarn-beam as to raise the click n" from its action on the ratchet-wheel l-", thereby leaving the yarnintroducedit will raise the roller '1' and al Y the main frame of theinachine instead of at.

by varing the diameter of said roller or by varying the number of teeth in the cogged wheel c" or in the contrate .ratchet-wheel e", and the contrate ratchet-wheel 1" should be so proportioned that 'the click nf", provided thatit is allowed to act on th rachetwheel 1" continually, will deliver out the required length of chain or warp when the yarn 0n the `beam is at the smallest diameter or about exhausted. 4

The mode of operating the Imachinery for delivering out the chain or warp and of tak ing up the finished cloth is as follows: When the lathe approaches the breast-beam to beat up the cloth, it moves the-sliding bar of, which, by means of the parts connected therewith, turns the ratehetwheelythc space of] one tooth and the ratchet-wheel Z" the space of one or more teeth, according as the'cliek n" is acted on by the roller 'im'. New suppose the roller i" vto be sunk to such a degree beam e'" at rest, it is evidentthat as the rollers d'." and e takep agiven length of finished cloth every thread ot woot or illing low the click n" to renew its action on they roller 'i'',and allow thelick nto renew its action on the, ratchet-wheel l" and deliver out a new portion'of the chain or warp. In case too much chain or warp is being given out, or, in other' words, when more is given out than is taken up by the rollers lV and le"", the roller 17'?" descends, raises the 4click n', and again entsgotl" its action' on the ratchet-wheel l. y The third improvement to be described is vthe mode of :constructing the shuttle and shuttle-boxes and of connecting said boxes to' taching-them to the lathe, as heretofore done. The shuttles 1 1 are made of a plate of iron end,a top' View of which is seen in 1""ig.IV an'd aside view ip Figi. An'jenlargcd view o f this part is also shown in Fig.A VI II; The round the shuttle 1, are pointed at the ends and, have a notch filed in the top side. 3 3 are guide-pins, the office of which will be de-v scribed in connection with-the parts which operate the shuttles. 4 is the pin or skewcr for holding the quill or bobbin, which mayv be made like thosein common use. 5is a spring to secure the quill to thepin or skewer` 4. The filling passes from the quill through ythe eye 6, under thebar or lever?, and out through the eye 8. The spiral spring 9 eti!N circles the fnlcrum of the lever 7 and acts thereon iu such a manner as to give a degree of friction to the filling in proportion tothe tension required; The shuttle-boxes 10 10 are formed of a table or plate of iron with a piece turned up at right angles on .one`edge,

vby which they are `secured to the arms 11,11.

An end view of thesh uttle-boxes 10 10 is seen in Fig. III, a front view-in Fig. I, and aplan in Fig. IV. 12 l2 are bars or guidesto guide the shuttle 1 .1. Thefb'ars 12 12 are made beveling on the edge against which the shuttle 1 bears to prevent the shuttle from rising up. 13 13- are springs or binders to secure the shuttles in the boxes. 14 l14 are pins ro- .jccting from the plate or table of the shuttleboxes to arrest'the shuttle when itv enters the box. The arms or levers 1l ll are affixed to their fulerum-shafts l5 15, which turn in the standards 16 16. lhe-adjusting-screws 17 17, to regulate the downward motion pf the shutt-le-boxes lO 10, rest on the standard 25, when said boxes are depressed to bring the shuttle A,

in the top box into operation. The standard 25 is bolted to the frame A A. The arms or levers 18 18 extend from the fulcrum-shafts 15 16 and are connected by the chains or rods 19 19 to the arms or levers 20 20,3whiehI are atlxed to the shaft 2l. 'lheshat't2l turns in the standards 22 22 and has the arm or lever 23 extending from it, which is connected to the treadle h by means of the cord orchain 24. The operati on of the shuttlefboxes is as follows: Suppose said boxes to be depressed 'to a-positiou to work the shuttle in tlretop box.v Then when it is required to work the shuttle in the lower box the cam b acts on tl 1etreadle`v h., and through the medium of the cords or chains 24 and 19. and. arms or levers 2O, 18,

and l1 raise the boxes to the position lshown .j

Now when it is require-d fin the drawings. to work the shuttle in the top box the cambr relieves its aetionon the treadle h and allows the boxes to ldescend byl their own gravity.Y Only two boxes are describedj'but any numi vbermay be` used which it ris. practicablejto work. One method ofusingase'ries .of .boxes will be noticed u nder the headjjof Modifica tions.

The arms 26 26 are 'grooved oeltherodge and slide on the gnideways 27 l27'.' 28 are latchin'g-levers for holding the d'fpins 2 2 on the shuttle in the ends of arms 26 '26. lhese levers vibrate on a 54 are axed, which cause said lever to lock `into the pins 2 2 when theycnter the holes.

.1, 34 vis a projection rising from the bar 32,

which strikes against the standard 35 ,when

the arm 26r is drawn back and meets said har while the arm 26 continues to move back. 55 55 are guide! support the-arms 26 26. 36 36 are standards tosupport the ways 27 ,with one end resting on the standard 37 f3.7fsud the'l other on the standard 25. Q ,38"38 are two gro'ovcd `cylinders or drums, 'thoouter ends of the` axles of which turn in the boxes 39 39, andthe reverse ends of whic are coupled to the lathe-shaft Q.

.40 40 are grooves in said cylinder, to which friction-rollers are fitted, said rollers 'turning on studs 41 41, which extend downward from the arms 26 26, when the cylinders or drums 38 38 are caused to revolve. The action of the ygrooves 40 40 upon the arms 26 26 will be such ls'will cause themV to vibrate back and forth through the lways in the .manner required. The cylinders which I have used are about thirty-two inches in diameter and about the same in length. They give a motion to the ,arms oftwenty-nine and a half inches. 42 42 are stands bolted to the standards'36 3 6.

43 43 are cams which act on the rollers 31 31 and operate the latching-levers 28 28.

44 44 are shafts turning in the bearings 45 45. 46 46 are arms extending from the shafts 44 44 and made hooked at their outer ends, and there hook onto the projection 34 and -ar'rest the bar 32. The arms 47 47 project downward from the shafts 44 44 and are conlllfted to the rod 48,by the rods 49 49. 50 is' a stud projecting from the rod 48 and playing in aslot in the upper end of the lever The' kin the next operation.

5r. 'The lever 51 vibrates on the fulcrum 52 v(see Fig. III) and has a stud projecting from its lower arm laying into the groove in the periphery of t e cam 53. The groove in the cam 53 'is so shaped Aas to give a vibrating motion to thelever 51 and slide the rod 48,

which, through'thefmedium ofv the rods 49 49 and the arms 47 47, turns the shafts 44 44 and raises one of the arms 46 and at the same time depresses the other. I In Figs. VI and VIII a shuttle and the appa'- -ratusconcerned in handing it from one ot the reciprocating arms to the other are shown on a l larger scale; but the respective parts are designated bythe same numbers as in Fig. 1.

`Their construction is thereby clearly shown. The mode of carrying the shuttles through the warpis vas follows: -Suppose the loom to be in that stage of its operation in whichv it is represented in the drawings-that is to say,

lthe 'arms 26 26 drawn back from the shuttle and the bar 32 moved forward, so as to relieve its action on the roller 30, thereby having the latching-leve'rs 28 28 free to lock onto the shuttle-pins 22, the respective parts being in this position, then when-,the shuttle is to be handed across the loom, the cy1in'ders`38 38 being made to revolve,as above stated,`will, by means of grooves 40 acting upon the fricy tion-rollers upon the studs 4L, carry the arms j 26 26 forward toward the middle of the loom; and .the arm 26 on that side of the loom where the shuttle lies which ist-o be'operated Y receives the pin 2 on the` shuttle and c 'arri said' shuttle forward until it meets the other arm 26,which also receives the pin 2 ou the reverse end of said shuttle.i Now in case neither-of the laughing-levers 28 28 were .rereleased from its action on the pins 22, thearms 2626 would beheld fast by being looked to their respective shuttlepins,' but toi-prevent this and to determine the directio'rof the shuttle after the arms 26 26 meetthearm`l`r 46 ou that side oi:` the loom from which th shuttle was 'takeniis depressed by the acon 1 of the cam 53, s'o that the projection 34 strikes'. against the hook thereon and draws back the bar 32 and releases its latching-lever 28. -I

have already said that when one of them.

46 46 is depressed the other rises. Consequently the arm 46 on the reverse side o f the loom from which the shuttle was taken would be raised and the projection 34 pass freelyuuder'it, and thereby leave the lateh-r v ing-lever locked on the shuttlepin`2.' The arms 26 26 now return, and when they arrive' at the proper point 'to discharge the shuttle the rollers 31 3l 4strike against the cams 43 43- and release the 'latehing-levers 28l 28,' and leave lthe shuttle in the shuttlebox,and at the same time the projection 34 on the bar 32, which was drawn bacle'te releasethe iatching-lever 28, when the arms 26 26 moet in the middle of the loom, strike the stand 35 and carries the bar 32 forward to leave the latching-lever 28 free to 'lock on the ,shuttle-pini! n v ne The mamimm to be described is me oth from d g in when the filling or woef is reventcd 'by any canse from escaplng free y from the shuttle, and also for stopping the loom' when the filling or weft breaks or is exhausted 'on the bobbin. .l

56 is a vertical shaft turning in the standards 57` 57 and has the forked arm 58 extending from it, which acts on the clutch J.

59 is a spiral spring encircling the shaft 56 a'nd acting thereon in such 'amauner as to turn it in adirection to disengage the clutch from the clutch-holder 60, and thereby to stop the loom. 61 is an arm extending from the shaft 56, by which the operator'throws the loom into a paratus for ntin the selva e of the ci g s gear.

62 is a rod jointed to the arm 61, and which slides in the frame A and the stand 63. When the operator moves the arm 61 to; ward the loom, the notch 64 filed in the side of therod 62-locks onto the arm 65 and secures the loom in gear, and when the arm 65 is. released from the notch 64 the spring 59 throws the loom out of gear. The arm 65 is 'amxe'd to the shaft 66, which tui-ns inthe ena frames A A, and has the handles 67 67, projecting upward, by which theioperator turns said shaft; and therebyl releases the arm 65 to stop the loom.

(38 is 4an arm extending downward from the shaft 6,6.

69 i's a rod, one endof which slides laterally in a horizontal slot in the standard 70, (see Fig. II,) and the other end turns on the upright stud'71. The upright' stud 71 projectsv from the slidingbar 72, which slides in the standards affixed to the Vframe A A, by which they are hidden in the drawings, but are of a character not to need description. From the l under side of the bar 72 the arm 74 projects,'

` which is acted on by the cam 75 and carries vforward the bar 72 and rod 69, and when said cam relieves its action on the arm 7 4 the bar 72 is forced, back again by the spiral spring I 76. The cam 75 is'screwed tothe nut az, and may be adjusted by the slot 77, and should be so placed 'as to-act on the arm. 74 at the time it is desired to throw the loom out of gear when the filling breaks or is exhausted. Vhen the shuttle is properly armed with filling, the rod G9 is kept to the left-hand side of the arm G8, so as to. pass freely by it when forced forward bythe cam 75 and no action is produced; but when the filling isbroken vor -is exhausted the vibrating' end oli-the rod 6D is made to present to the side of the arm 68,

so that when said rod is moved forward. Iby

-the 4cam T5 it turns the shaft 66 and throws the loom out of gear.

The apparatus for regulating the action of the rod 6U on the arm 'U8 and for preventing the selvage of the cloth from drawing in whe'n -the filling isi-obstructed in its deliveryffrom the-s1uttle is constructed as follows.- j

97 8 is a horizontal shaft turning inthestandry 7 7o. p

80 are vertical shafts, the upper-'ends of which turn in the shaft 78 and the lower ends thereof in the stands 8l 8l,screwe'd fothennder side of the shaft 78. From the vertical lshafts 8()v 80y the arms 82 82. extend, whichV have two projections rising from their upper sides, through which one leg of each of the. wire hooks 83 83 slides.

84 84 are spiral springs to throw the hooks' 83 83 forward.

85 85 are collars screwedto the hooks 83'83 and made flat on theillnder sides to rest on the top sides of the arms 82 82 to'keep the hooks S3 83 from turning round. The collars 85 85 limit the motion given to the hooks'83 83 by the spiral springs 84 84.

86 86 are arms, one of which extends from the front side of one of the vertical shafts 80 and the other from thebaek side of the other shaft 80, and are connected togetherby the rod 87 in such a manner as that when one of the' shafts 80 8O turns in one direction other turns in the opposite direction.

88 is an extension of the roll 87, and has a downward projection at the end, in which a vertical slot is made to receive the rod G9.

This slot allows the shaft `'78 to vibrate without moving the rod 69. The spiral spring 89 acts on the rod 87 and throws the'arms 82 82 out of the position seen in Fig. (IV.)

90 is an arm extending from one of the'verf tical shafts`80 80, and which limits the approach of the arms 82 82 toward the cloth hy striking 'against Athe stand 81. Thearm 91, extending from the'shaft 78, has the roller92 revolving'on. a stud at its lower end, whichis acted on by the cam A93 lund vibrates the shaft 78.

This apparatus'operates as follows: When the loom is in that stage of its operation in which thelathe is falling backward, the warps opening, and the shuttle about to start, the cam 93, through the medium of the roller 92 and arm 91, turns the shaft 78, thereby raising up the points of the wire hooks 83 83 for:

ward of' the filling,so that when the vshuttle passes the thread of filling which said shuttle carries draws round thel point 'of the wine hook, which is at that side of the loom from.

which the shuttle is taken, and `draws said hok toward the selvage of the cloth 'until the "arm .90 strikes against the stand 81, which prevents its further fapproach, and therebyk prevents the filling from drawing the selvago of the cloth' when it is 'obstructed v in its delivery frorn the shuttle. 4W-hon the filling is drawn round the hook 83, asaforesaid, the spiral spring 84 84 allows said hooks to ad. just themselves to the face of the cloth. When. the hooks 83 88 are drawn up to the selvage. of -the cloth, as aforesaid, they move the-vb brating end of the rod t9v to the` left side of the arm 68, and in casethle' filling vis running prperly from the 'shuttle retainsaid rod in t Jort nnder of the spi-M3789 and bringlthe rod 69 in position to act pn the arm 68 nnd throw the i `bom out of gear. When theloom has prolNederl i0 that s eof its o rntionat which Hnflhnttle il abtrgt toentell'wthe shuttle-box, them 93 relievesits sction on the arm 9], Ind the weight of said arm draws thehooks 8383 outi'rom the lling and allows it to close V 'into the'elvsge, and also allows said hooks .',tffreexthemselves from the lathe" when it iblstl'dpthe cloth.

There are various* other modes of arranging the Jacqunrdv lmachine nnd'of mounting the loomy which are well understood by weavers and which may be variedaccording to the kind or style of goods to be produced. These various modes of arranging the Jacquard mn-u chine and of mounting the loom iu'ay be ap` `pled--snd I intend to apply the|n-v ,in con-'- nection with my improvements, varying them according to the style of goods to be woven.

The table or piece of cast- 10 has a V-shaped groove to receive the un-v der side of the shuttle-frame a. 14 is the ar- -'rest1ngpin to arrest the shuttle, and 13 is the shuttle-binder, which guides the top of they shuttle-frame a and secures the shuttle in the box.. The shuttle-binder 13 has a notch in its under side, as shown in No. 2, FigJVLwhich guides the topof the shuttle-frame aa. The

' shuttle-binder 13 is bolted tothe table or piece of castin 10. The shuttle-boxes thus formed are bol ed to the arm 11, as shown in Nos. 2 and 3, Fig.'V. The arm 11 is to be attached to a shaft and operated-in the same mannery as the arm supporting the shuttleboxes described in the precedingpart of the foregoing specification. Fifth. The following is a mode of arranging and operating a. series of shuttle boxes in separate frames, audis represented in Fig. VII: vertical frame is suspended from the upper illoor of the mill at each side of the loom, to the back side of which frame a shuttls-box is attached, and on the f ront side of said frame another frame is so arranged as to slide up and down freely. To this lastnamed frame a series of boxes are attached. The frame carrying this series of `boxes is ur'oved up 'and' dow/ by means of a toothed raelfand cogged wheel for the purpose of bringing the different shuttles into operation which contain the filling to form the figure, said cogged wheel being made to operate lat proper intervals by the action of the J aequard machine. The shuttle containing the groundfilling is placed in the box ou the back sidev of the suspended frame, and the shuttles car-4 rying the various colored filling for the figure are placed in the series of boxes-ou vthe slidying frame., The shuttle carrying the groundfilling and one of .the shuttles carrying the into operation alternately by a swinging'v motion given to the suspended frame. A A,'Fig. VII,isapart of the said frame of the loom. q is the upper /lloor of the mill. f is the frame suspended from the flcnrlq, with a shuttle-'box aixed to the back side thereof at g- .h 'is the slidiing frame, to which is' attached aseries of boxes varyingv in inumber according to convenience. In the present drawings only three are represented. The red line t' represents a,

strap or cord passing over a pulley on the.

axis of the frame fand overthe pulley;l to

fbeweight-k, which is suspended therefrom. '.lfhe weight k is employed to counteract the weight of the sliding frame h. A 'inging or vibratory motion is given to the frame f by means of the bar l, the arm 20, and the Ishaft 21,1 said shaft 2l being turned by the action of alcam and treadle in the same manner in which it is turned to operate the shuttlc-boxes, as set forth in the preceding part ot' thisspecificatin. This vibratingor swinging motion brings .the shuttle carrying the ground-filling and one of the shuttles carrying the filling to form the figure alternately into operation. i y

' The mode of raisingand depressing the frame h to bring `the various shuttles into" operation containing the different colored Mling required to formV the figures is ssffol-r lows: m is a cogged wheel (shown in the drawings by dotted lines) affixed to the shaft n, andV this wheel takes into the toothed rack on the frame h'. The shaftn turns in the stands o o and has the wheel p affixed thereto. q isa spring, one end of which is aixed to the frame f. The other`end is formed with a projection which takes into notches made to re-y l ceive itin the periphery of the wheel p. From the outer side of the wheel p the pins s s extend. 'is a latch to act on the pins s sin order to turn the wheel p. The latch r is connected with one of the knot-cords of the Jacquard frame, which at proper intervals causes it to act on the pins s s, and the upper or under arm is made to act on its respective pin, yaccording as thef'rame'h is to be raised or deressed. From this description it will be evident that when the upper ar ofthe latch ,1' is depressed, as seen in Fig. V ,and the frame j moved backward, said arm will then act on the pin s and turn the wheel p the space of one pin, will depress the frame h and bring a new shuttle into operation. When the frame histo be raised, the lower arm of the latch r is made to act on the pin s, which will give a reversed motion to the wheelp. This mode of arranging and working a series of shuttle-boxes is applicable, and I intend to apply it to looms in which the ily-shuttle motion is used, thel variation in the motion when so applied being n obvious, and therefore not requiring to be described.

In the application of the principles herein pointed out as constituting my invention I do not wish to limit myself to the special constructions and arrangements herein pointedl out, nor to the modificationsl set forth, as th'e'ff invention is susceptible of many more modifications; but I have givenv a full, clear, and exact description of that mode of construct-ion which I have assayed and deem the best, and only such modifications as I orignall y contemplated as illustrative of the faci -ty with which modifications may be made in the mere constructionand operation and' without departing from the principles which characterize my invention.
