To all whom it may concern: y Be it known that I, ERAsrUs B. vBlcnLovv, of Clintonville, in the county of Worcester and State of Massachusetts, have invented certain new and useful improvements in the powerloom for weaving two or three ply carpets and other figured fabrics; and I hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes them from allother things before known, and of the manner of making,

constructing, and using` the same, reference being had to the accompanying drawings, mak-ing part of this speciication,.in which- Figure 1 is a front elevation of-acarpetloom on my improved plan; Fig. 2, an eleva- The same letters indicatelke parts in all the figures.

In my improved loom the shuttle-boxes are in separate and independent frames by the side of the lay; hence when the shuttles yare thrown the lay must be at rest and in a. position relatively to the shuttleboxes .which shall always be the same; but the power required to work the lay is very great, partielllarlyn lieavy carpet-looms, and the parts employed in working the lay are in consequence n much exposed to wear and strain.

It the same means be used for holding the lay in a fixed position during the throw of the shuttle and for beating, wear and strain would be liable to put it ont of true.

Itis the-objectof the first part of my invention to avoid this difficulty; and tol this end my invention consists in using one cam and roller to work the lay and another'to hold it t in the iixedlposition during the throw of the shuttle, one of the said -cams being on the layahaft, and the rollerwhich works in connection with it on the lay, and the other cam on the lay and its roller or wrist attached to the rst cam; one of the cams being concentric to hld the layin a fixed position during a part I f H of the rotationl and during the time the shuteither gradually started or gradually arrested,

and the other cambeing of any form thatmay be desired to give to the lay the varying motions required, and with its ends adapted to receive and liberate the roller which it operates. By this means the'cani and roller which operate the lay, and which are exposed to all the wear and strain, are not used to hold the lay in place during the throwk of the shuttle, thisbeing done by the other cam, which, being concentric, has no strain upon it, as its object is 4simply to hold the lay in a state of rest.

I have combined in one loom two series of shitting shuttle-boxes and two stationaryor receiving shuttle-boxes-that is, one series of shifting shuttle-boxes and one receiving shuttie-box on each side of the loom, and hung on separate frames independent of the lay of the loom; but for many kinds of fabrics four-:series of shifting shuttle-boxes are rfxlurcd; and the second part of my invention consists in combining'wvith a power-loom four series of shifting shuttle-boxes, two on each side, and hung in separate frames at thesidcs and independent of the lay,the said fourseries of shuttleboxes receiving motion fromthe loom, or'from some first mover in connection with or operating in unisonwith the loom. When series of shifting shuttle-boxes are vemployed at the sides of the lay, and in frames separate and independent ot' the lay, the usual protector;

combined with the shipper for stopping the t loom when the shuttle fails to pass through, cannot be employed; and with a view to ac- .complish this important end inl this connec- -tion the third part 'of my in combining with the shipper, or any other stop motion which may be used as the equivalent thereof, a protector for each series of shuttle-boxes hungl and operated in separate frames independent of the lay. As the vshuttles pass from t-he shuttle-boxes to' the race-,board of the lay, either the ends of the lay must work close to the boxes, or there' should be-guides from the shuttle-boxes to the ends of the lay to guide the shuttleas it passes from the one to the other; but as the shuttle is not driven homej7 sometimes the projection y invention consists of the `ihnttle beyond its box will of necessity catch he lay. aud break some parts fathe mechanism. fr

It is the object of the last part of niyinvention to provide against this evil; and to this end the last part of my invention consists in combining with the lay and the shuttle-boxes in separate and independent frames by the side of it hinged guides to guide the shuttle from the one to the other, and to yield and thereby prevent breaking whenever a shuttle or any ,pai-tof titervenesbetween the lay and the shuttle kbox Vor boxes hithe several drawings of my said looiulor" -weaving ingrain or-va rious other" fabrics I havenot exhibited tlieJacquard machine, the vfharneses, nor. the cams and treadles by which they are operated; neither have I represented Y the let-offend take-up machinery or motions, i. as Vthese make no part of my present invention.

C is the j' main or,drivingshaft .whose journals are supported andvrevolve, in boxe"s D D,applied to thetops of two standards, E E. The said main shaft has one fast pnlley,G,and one loose-pul- ,ley,H arranged uponornear one endof it, as

geen in Fig. 1. i The bandthatpro'ceeds' from the movingspower'and actuates the loom is caused to pass around and made to turn one -.northe'other of the said pulleys, it being thrown ',.uponthe' fast pulleywhen the loom is tobe put i-nfaetion and upon the loosepulley when the loom is tobe stopped. Thesaid band is to be moved from one to theothcr by a shiftingfork E j or lever, 1 such"as isgenerally used in. looms. f A Altoothed pinion, K,;on.-the dri-vingshalt en- I .gageswith a large. tQQthedwheel, L, fixed upon :the horizontal lay-shaft M, and consequently,

when revolved, imparts a rotating movement' f to Vthe `said shaft. Upon the lay-shaft M is Vanother cogged wheel,` X, (see Figs. l, 6,-)

which engages with 'a cogged wheel, Y, fixed uponanother short horizontal shaft, Z, and thereby wh'euit (thecogged wheel X) revolves 3 it imparts motiony to thesaid shaft Z. The

shaft Z has a cogged'fpinion, e, affixed VuponA or'near one end of it. The saidpinion engages with a gear-wheel, d, xed upon a horizontal eaisai; cig-The cams by Whichth'e-.Iac-

./quard apparatus is operated are tobe placed upon vthis latter shaft. They are lnot 1repre-1 sented in the'drawings, as vthey constitute no part of my new improvements. lThesaid shaft;

the gear ge" 'with thirty, the gear i with sixty.' the gearfbawith twenty-five, with" fifty, of said teeth. y

The first improvement' to be described is `the mechanism by which tbe lay is operated; In this loom the shuttle-boxes being disconnected from the lay require the latter to' be moved quicker when it beats up the cloth, also to remain at rest when thes'huttles are thrown, all of which is effected by the mechanism which I shall proceed to explain.

N denotes the race-beam of the lay,I and O P the swords thereof, thesain" being-attached to the loom-framedn the u'sua "mannen `The said lay is operated'q'r moved backward and forward by means of two Vgrooved cams, Q Q, fixed vupon th'e ends of` the lay-shaft M, there being one of said canis on `each end of said shaft, as 4seen v`inztlie drawings. Ilach ofthe saidl cams is grooved uponl itsouter face, as

seen in Figs. 3 andfifanld -sniore particularly rbeing made to turn orl lrevolve upolu acylindrieal pin, S, insertedin and projecting from the camand between -`the two .extremities of .its groove, as denoted in the last-named figure.'

VThe passage 4T'has airopening, U, at `top, and another, V, at bottorn,the-said openings being for the-purposebf allowing the roller R to enter into and depart from the Vpassage T during ythe revolutionl of the cam rIhere is another and similar roller, -W,

similarly applied' to the rearside of each sword in the position as seen in the drawings, the said roller being received or acting Vwithin the groove of the-.camQ during a portion of its revolution. v K It is by means of the grooves ofthe two cams, the passages of the two swords, aud their re-V spective rollers, as `abovedescribed, that the lay is caused to advance, retreat, or remain stationary during proper intervals of time, in orderto allow of the cha-nge of the warps and operation of the shuttles. v The main object in.

the employment of two cams and two rollers at each end of the layfis .to prevent, as far as possible, the 'wearingof the roller .,W, which l'moves inthe grooveof ythe cam Q, for it is by `means of the said lroller th'at'the lay is kept `perfectlyv stationary Vduring 'the throw Vof av Y shuttle, the roller then'inoving or passing throu'gliathe concentric ,partlof the groove of the cam Q. rll-his .roller should lity welland play so closely-in' the said'concentricpart of the grooveas tokeep'the 'front face of the reed perfectly still and in its proper'place during a'throw of a shuttle, for wereit not andthe gear a so a verytr/iiling forward movement of the lay would cause the shuttle to be thrown out of the loom, or to miss the shuttle-boxinto which it is to be thrown. When the lay beats up, the roller R, moving in the middle part of 'the passage T, drives or forces the reed against j the filling, and performs such office in the place of the other roller. Therefore all or most of the friction which tends to wear the rollers is thrown upon the roller R, and the difficulty which would soon arise from a reduction of the diameter of the roller W is thus avoided.v

The next or succeeding improvementto .be described is the manner in which I combine -and operate four sets or series of shuttle-boxes. By means of the same arranged and working together, as hereinafter described, I am envabled to adapt my improvedloom to the weaving of a great variety of styles and descriptions of goods.

The peculiar nat-ure or character of my improvement to be nowexplained consists of a' the said sets of shuttle-boxes, any or all of them,beng.made at suitable times torise and fall or move upward or downward, so as to change the positions of the respective shuttleboxes of the one to those of the other, i-n the y manner as will be hereinafter explained.

The four sets of shuttle-boxes are repre-A sented at d. d', and c c,e e', Etc., as seen invFig.

-are disposed in front of the others, respective ly'.

Each two adjacent sets are applied to one of two vibrating frames, each of which is com posed of two rails or bars, s t or u c, which are kept -iu their parallel positions by any number Vof cross rods or bars c c' extending from one of the said rails to the other, (of eitherl two thereof as seen in Fig. l, and being properly secured to the same. Fig. 10 is a.

vertical and central section of the two series of shuttle-boxes-d d', &c., g', while Fig. l1 is a. similar section of the series e' e e', Src., f f, 'each section beingtaken as if the eye of the spectator were directed toward the lathe.

` The shuttle-boxes of each set d d', &c., e're',

Snc., are made ofa series of shelves, h h', arranged withregard to one another,and projecting from a plate, i', as represented in the drawings. Each shelf has a plate, k', affixed to its outer or front edge, so as to extend above and below it, as seen in Figs. 1, 10, 11. Each plate i' should be applied to its rails s t or uv in such manner as to slide freely up and down between plates or secondary rails l'l, fastened to the said rails .s t or u c in .the positions as seen in the drawings. A counterbalanceweight., m', is applied to each of said series of shuttleboxes d' d', Src., ee', &c., by means ofte chain, n', which is attached at one end to the top part of the plate li, from thence extends upward and is wound'several times around a helical-grooved pulley, o', upon a shaft, p' or q'. thence passes over a grooved pulley, p', in rear of pulley o', and is fastened to the depending counterbalance-'weiglit m', as seen in the drawings. The series f f of shuttle boxes is also to be applied to the frame or rails s t, so as to be capable of being raised and lowered by mechanism such as I shall hereinaftery describe.

The shuttle-box g' is made stationary between its rails u c; orl insteadtheilef aser-ies of boxes made to operate like the seriesff, may be employed when the fabric to' be wrought requires the same. 'The 'vibrating l frames which sustain the four series of shuttle-boxes are each to be made by theirv mechanism to advance or retreat a suicient distance and in such manner as to alternatelyl bring one of the shuttle-boxes of each series attached to it into range with'tlre racebeam of the lay when the said race-beam has retreated to the utmost allowable extent. The' said vibrating frames should be so moved in connection with one another that -whenever vany one shuttle-box of the front series of shut`` tle-boxes of the one frame is inl range with the race-beam of the lay some one shuttle-box of the rear series of shuttle-boxes'of the other frame shall be-also inlinewiththe lay. Openings suitable to permit the passage of a shuttle from each shuttlebox of the two series f f g' should be made through the inner rails, tu.

One of thesaid openings, or that which belongs to the'shuttle-boxesf f', is partially ex-A hibited at r', in Fig. 6, the ot-her opening is.

represented at s', in Fig. 10.

. In weaving common two-ply carpeting the shuttles containing the variousfcolor'ed lling required to form the first or ground ply of the carpet are placed in Ione of the front-series vof s liutt-lefboxes, and the shuttles containing the filling required to form tlie second or figured ply of the carpet are placed in the other front series of shuttlcboxes, and. a thread of filling from each class of colors is alternately introduced into the warps-first a thread from the grou nd-ply, then a thread from the figured ply, then one for the ground, and so on. Now,

by moving the vibratory frames simultaneously in opposite directions and causing the shuttles of either of the front series of boxes to work into their respective back box or series ofboxes, as aforesaid, the said two classes of colors are kept separate from each other during the process of weaving and changing the shuttle-boxes.

In weaving 'styles of twoply carpets, known as plain and pillured ground,7 an even number of threads of any given color is always introduced. Consequently a. shuttle thrown from any one of either of the front series of shuttle'-` v l boxes always returns to it again' before a chalige 1s required. Therefore, byl moving-the front ser-ies of shuttlelboxes up and down at proper main unchanged In weaving `l Y v .intervalsif'tim ,'"as hereinafterto be. de-

scribed,`(the sai ifrcntseries containing the filling for thesec nd o r figured ply,) and alvlowngthe other, ront series of boxes toreto their vertical position, I can produce a y variety of two-ply carpeting .of the sty] known nsfplain ground.

-By movingbot of the front series of shuttle` boxes up and don at proper intervals of time, as aforesaid, and allowing the two back series Ao f boxes to remaiii unaltered as to their vertical positions, I can produce al), or nearly all, theehanges required to weave the various pat lared ground.

- iterns of carpeting ofthe style kuownas pilmay-be made ly moving-the vibratory frames backward and forward simultaneouslyand working the two front series together. Espe:

, ,cially isthis desirable-in -weaving some styles `of three-ply carpeting. In'weaving more simple 'styles of `goods Ias'o'metimes allow-the'vi bratoryshuttle-frame to remain at rest and I work only th'e front series of boxes.

Having vthus described the manner in which the various sets of sh uttle-boxes operate with respect to-eacli other, I shallnow explain the mechanism by which they are moved', not only back 'and' forth, ebut upward and downward.

' The rails or bars s t or 'u 1:, before mentioned as composingA part of the vibratory shuttle-box frames, are each supported at its upper end by," Iand so as to` turn or vibrate upon', one of fou'r center pins, 1 1 y, &c., projecting, respectively',`

' from four standards, z z, &c whichextend the styleof carpets known asr4 fshot-about, or shot and shot the groundrig. 1,) there 'being twoof the said standards *to each shaft, as seenin the drawings. Each Yshaft l m has two cranks ,on arms,'ppV or q q.

Y the vibratory frames simultaneouslyinopposite directions, as aforesaid, the cranks p, p of one shaft,l,project from it in directionsopposite to those in which the-,cranks qq'ofthe other shaft extend .therefro1 n as will bei y'seen by inspection of Figs..3'and 4r; but when it is desired to move the'.vib r'jat oxjy frames `simultaneously in .the-same direction "sai`d cranks are ymade to project from their respective shaftsin the same directionv Eachroller of each of said cranks plays i,n'fone'of fonr upright grooves formedpninadelin Ithe,lower lparts of four rails, stu11,orinplates'w10,8162,

Now, when the grooved cam @imparts motion to the shaft e, the toothedsectorsjj will-act upon the coggedfwheels Ryland thus ,partially turn the shafts l m inftheirbearings, and iu such manner as to cause the outer ends of two of the vcranks p p or q iqftoniove `touf'ard the front, and. the .outer'fends' of vthe other..v two cranksto move'toward lthe rear of the loom.

Such movements of the said-cranks will .make corresponding movements `of the rails t u i. .The nex't'portion of t he machinery to be described is-that by which the two front seriesy lol" shuttle #boxeswdg d:, &c.,' e' ef, die.,

'The vibrating shuttle-box frames are vibrat# ed or moved by mechanism as follows: A grooved cam, a, is fi'xed upon the shaft zin the position, as seen in Figs. l and 6, the shape'of the said earn and its groove being f represented in the latter figure. The groove b of the said cam receives Va roller, which projects from the upper part of an arm, (1, ex- Vtending upward from and lbeing aixed to a Xiong-'horizontal shaft, e, whose journals near 'its ends are supported so asto turn in suitable bearifngsf,j f,.,{seef,1?i, gs. 5 and 6,); projecting @from two' standards, gh. Upou'tlef'endsof' said shaft two toothed'sectors, i "i, are fixed, '5 and 6, thearni `'being represented in the 'f-s seen iuv Figs. 3 and 4.' The said sectors enformer figure and the.`arm p in the' latter,

The arm o3 andjthe rlghtserles` of'shuttle-boxesto A journals of the said horizontal'shafts are supbeimoved is substantially simi-lar to that which ported and turn in,boxes n n n n, applied to intervenesbetweenthe arm p and the leftsethe tops of four vertical standards, g Il o o, (see riesxof'such' boxes, as willl be seen by inspecs een in Figs.l 1 and 6. ffirbovelthefsaidfcam f a lever, g, is arranged, as seenin the drawings, the said lever turning Ona pin'r ful4 crurn, Ia-3, at its'inner end, and having a fricg., tion-`roll, i, appliedto' its front end and resting upon the vcam f. Thesaid leverhns thc lower yend of -a vertical rod,k",.=j.ointed to itin' rear ofl itsroll, as-.seen in' Fig-26,1. the upper end of vsaid rod being ljointedfto the extremity Y of an arm, l'which projects froma horizontal shaft, m, f whose journals -rest land move in bearings n3 n, arrangedas seeny inl the`dra.-W- ings.- The s ad shaft in3 should have-two more arms, o3 p, projecting from itin the rear, iu the position-thereouja'sin Figs. land 2, and of .the forinand length as denoted in Figs.

' sented in Fig. 5.

14a l s l ported so as to slide upand down upon a vertical rod, s, properly sustained in position.

' The said frame r carries two depending levers,

t u, which are, jointed' to it at their upper ends,'or so that the lower end of each may move freely back and forth toward or from a circular wheel or plate,v, disposed with respect to the lower ends of said levers, as seen in Figs. 1 and 6, and fixed upon the inner end of the shaft p', which has fixed upon it the helical grooved pulley o', as before described. The said circular plate orY wheel has a series of six pins, w w, &c., inserted in and projecting from its inner edge, as seen in Figs. 1, 2, and 6. y The said plate has also another series of six' pins, y y, &c., (see Fig. 2,) projecting from the opposite side of it and arranged equidistant from each other in a manner similar to that in lwhich the pins w 1v ou the other side of the plate are disposed, butin positions with regard to said pins w* wl, as exhibited by dottedcircles f y" in Fig. 6.

By inspection of Fig. 6 it will be seen that the lower ends of the levers t3 uare notched, as'seen at z i. It will alsobe seen `that directly below the wheel c there is a stop, a,

4 which is shaped as seen in the drawings, and

plays vertically between guides b b, fastened l to the vibrating shuttle-box frame. r1`he saidy stop is forced upward or against such pins y y as it may rest in contact with by a helical spring, c, which rests upon the lower guide b, and passes against ashoulder or button, d, fixed upon the shank of the stop. The object ofthe said stop is to hold the series of shuttleboxes in their correct position after either of the depending leverst. u has been moved downward and partially revolved the wheel c. the said correct position insured by thestop pressing at one and the same time against two of the -pins y yl, &c., and while it so presses against them it prevents thewheel c from being turned around by any other power than that of the depending levers t us, whose action upon said platel shall now proceed more particularly to describe. The two depending levers tj* w| are connected by a helical spring, e, one end of which is secured to one and the other end to the other of them, the said spring operating by its contractile force in such manner as to draw the levers t u" toward each other. Each of the said levers has a small bent lever, j', arranged with respect to it, as seen in the drawings, and turning upon a fixed i'ulcrum,

One arm of the said bent lever f* bears against the lever to which it belongs, and when raised upward (which takes place when the other arm isderessed) itthrows the depending lever away Afrom the wheel't. The other arm has a chain or cord, hjaaached miewwhich l chainor cord aweight, i, is appended, asseen in Fig. 6, the said weight .being of sufficient size to pull down the said arm of the lever aud `overcome the contractile power of the spring e, and thereby throw its lever t3 or ua so far beyond the wheel c as not to act upon it (the wheel) when it (the lever) descends, aswillfbe hereinafter described. There being two of the said bent levers ff, each is to be provided with its cordvh and weight it, as seen in the drawings. v .y I v i As a common Jacquard apparatus is to be applied to this loom forthe'purpose of raising the warp-threads in order to weave figured fabrics, it is intended that the up-and-down movements of the two series o f front shuttleboxes shall be regulated and determined b v the same. In order to accomplish the said movements, it will only be necessary to connect the four cords h h, Figs. 1, 5, 6, or their weights, with four ofthe knot-cords of the J acquard apparatus, and to prepare the pattern card or cardszof said Jacquard apparatus so as to permit of the elevation of the cords h h* h* h* or their weights in the order required.

In Figs. 1, 2, 5,-and 6 the aforesaid jacquard cords are shown at k* k, Src., the Jacquard apparatus being supposed to'be disposed above the loom. Now, whenever by the operation of the Jacquard apparatus one of the cordskis pulled upward so far as to raise the weight appended to it, the spring e, being relieved from the action of the weight, will contract and draw inward or toward the wheel 'u3 the lower end of that lever to the cord of whose bent .lever f the cord k* may be attached. It should draw the .lower end of said lever so far inward or toward the vertical line passing through the center of the inner face of the wheel if as t-o bring thenotch s of said lever perpendicularlyvover one of the pins w, which projects from the inner face of the wheel c. Consequentlythe said lever is forced downward Y lwith .a sufficient-degree of power, its lower end will be pressed against the pin wf directly beneath it, and will partially turn the wheel v", the shaft p', and the helical grooved pulley o', and in such manner as to either allow the series of shuttle-boxes suspended to the chain which passes around said pulley o' to descend by the action of gravi-ty ,a distance equal to that which exists between the bottoms-#that is to say, those parts'rin which the shuttlesrest-ot' either two consecutive shuttle-boxes I of the series, or to cause the said series of shuttlc-boxes to rise` upward a like distance. The saidelevation orl depression of-r the series .ot'

shuttle-boxesdepends upon whether the front or rear depending lever, t or u, is put in ac-` tion so as to turn the wheel c. If the front lever, t, is made to operate on the wheel v, the series of shuttle-boxes will descend. When the rear lever, u, operates upon the wheel el, it causes the said wheel audits shaft p and pullley o' to partially revolve in an opposite direction, and therefore elevate the series shutwhich may be nextto it, and which may have y, been brought into avhorizontal or nearly yzontal line withthe former.l

As the pickers during the process of weaning sometimes fail to free themselves from th`e "shuttle-boxes, and as the lshuttles sometimes project from the shuttle-boxes, sofas to prevent them from being easily moved, it is very important, `in order to prevent accident to 'or breaking of the machinery, that the power which moves thevshuttle-boxes up anddown Hhe applied inrsuch a way as to cease to act bey `youd a certain extent when said contingencies t arise. This I effect inthe following manner: vThe cam j'3 is employed simply to elevate the lever g, and thereby raise the -frame of the depending levers i u3,\or,'in other words, as said cam f produces no depressionof the frame of depending. levels, (they being made to `fall by the action of gravity, asdescribed,) no aceident can occur to the mechanism `of the loom should a picker at any time project into one of the shuttleboxes of one of the front seri- `thereof in such manner as to prevent it from moving eitherup or down. In such a state of I things one of the depending le'vers iu its de scent would meet and-rest upon someI one of the pins w of the wheel v, and would remain thereon withoutexerting any inj urions effect 'upon the series ofashuttle-boxes. As asubstitnte frthesimple cam and weight,l operating iasabove described, 4I sometimes .employ-a double or grooved cam,` and make 'the' rod-k' in two parts or sections or lengths,`

jointed together in' such manner as to readily .pu-ll'parto'r vseparate from one another whenever the piekersso `prevent the series ofshuttle-boxes from-moving either up or' i down, as the case may require.

Having th sdescl'ibed the mechanism for elevating or epressing the two front series of shuttle-boxeal shall now proceed to set forth .and explain that by whichthe rear series of shuttle-boxes areoperated. A cam, n, Figs. 2, 5,- 'of the shape denoted in Fig. 5, is placed upon the shaft c'.' Directly over the said cam v a lever, o, which' turnson a fulerum, p, is arf,ranged,'as seen in Figs. 2, 5. The said lever has a weight, g, hung upon its'lfront end of sutlicient' sizeto raise the shuttle-boxes when -the said weight is allowed t'o descend. Y It also has a suitable -friction-roller, R, applied to its side, and-so as Yto revolve and rest upon the periphery ofthecam. A rod, nl,.isjointed to@ the lever oL-near4 the. friction-roller and ex'-- tends upward and isjoiuted toangarm, t,

Figs. 2, 3, which projects rearward from a -horizontal shaft, f, arranged so 'as to be supported and turn in bearings/v* fv vf, situated as represented'jn-Fig- The said shaft e* has two arms, w* w", projecting from it, as seen in at their lowerends 'tof the system ff of rear shuttle-boxes. In the back series of shuttleboxesther'eis the same liability to break the machinery when the pickers or shuttles prevent'their free movement Aas inthe front se- 'ries of shuttle -boxes aforementioned. vTo

avoid accident thereby, I raise said boxes by the power ofthe weight q, applied inthe manner above described, and allow'them tode sceud again by their own gravity when the action of said weight is overcomeA bythe cam nf, as aforesaid. As theback series of boxes are required to rise andffall at different'times relative to the other motions of the loom, according to the style of goods to be wrought, it is obvious that corresponding changes should be 'made in' the canl'n, and as the time i'u which said boxes are required to operate will be apparent to every practical weaver I do not think it neeessaryto'desribe them in ietail. The cam should be so shaped as to ra se the weight q when -the boxes are to be Vdepressd,and to allow said weight to descend when the boxes are to be raised.

Although' I have described the cam i and weightas applied to moving lthe back` series of hoxes,itl is obvious that they may be applied to moving the front series also when the 'fabric to be wrought requires but few changes.

The next portion of my improvements is that by which the picker-staffs are operated in the order required to throw the shuttles. A pieker, i', is to be applied to each series of shut.- tle-boxes, the said picker beingarranged and made -to traverse toward and from the lay, or horizontal reds u u,;,disposed in a proper manner with respect totthe shuttle-boxes and secured to the vibratingshuttle-box frames s' tu e. The several pickers are each operated by one of fon'r pieker-sta'syv 'w' x y',arranged as' seen in theV drawings. Each of the.' front pickerstad'smfw, is attached to one, of the two shafts z' z', Fig. l, the same being more particularly exhibited in Fig. 12, which represents a` vertical and longitudinal section of one Fig. 2) attached them. Each of the straps ol' the pickerstatfs isffattached ,to one arm of one of a series of four bent levers, e, arranged -upon a transverse shaft or common fulerum, f i, (see Figsl and 2,) whichfprojects from a standard, g2, secured to the framework over-fthe At its opposite end it has an arm,

The back picker-stati', .or y', of each ofthe rear pickers is supported at .its I upper vend and turns upon the shaft loom. One of the said levers is detached from the shaft or fulcrum, as represented in Fig. 13. One arm of each of said levers extends from the fulcrum toward the right. Two arms of two of the levers project above their fulcrum, and two arms of the other two levers project below it. The said bent leversin conjunction with other mechanism to be described are intended to operate the piek er-st-as, which they do through the straps thereof, each of 1 which straps is connected with the extremity l -of each of said rods should have a small hook or shoulder formed upon it, as seen at m* in Fig. 3. The several hooks or lower parts of the rods are arranged side by side and kept in their correct positions with regard to the frame and other parts of the mechanism by means of a small guide-block, n, fastened to the end of the main frame. A top view of l the said guideblock is representedin Fig. 14,whereinit will be observed that it is drawnl with four elongated slots or passages, o p" g2 r2. The rod h2 passes through the passage o?. so with regard to the rods fk l, they pass in the same manner through thepassages p2 q2 r,'respeetivey. The passages are made suiiciently long and arranged parallel to one another and tothe end ot' the cast-iron fratrie 'in order to. allow the lower end of either of the rods h.2 y L2 l2. to

' move forward in a direction toward a lever,

s, arranged so as to move up or down in vertical direction and upon a fulcrum or pinpt', at its front end, as seen in Fig. 3. A top view of the said lever s2 is represented in Fig. 15, and a side view in lig. 16, the latter also ex! lhibiting a portiou'ot' the lower part of the cam Q, situated direct-ly above the lever. as seen in Fig. 3. The said lever s2 has a proi jection, t", extending horizontally at right angl'es to its front end,.as seen in Fig. 15; also a curved piece of metal, u2, afiixed upon its top at or near its central part, the said piece u being of the shape as seen in Fig. 1,6. A small roller, r, projects from the left side of the cam Q, as seen in Fig. 1, and also in Fig. 16, and when the cam'is revolved it carries the said roller in contact with and raises it entirely over the curved cam piece of metal ul,'a nd by- .so doing depresses the rear end of the lever.

The lever is elevated after the roller oeeases to depress it by a spring, w, (see Fig. 1,) arranged wthin va ease, rv", situated as seen in Fig. 3. Each of the rods h iik lz'has a small cam or projection, y, side ashort distance above its hooked end, the

said ca m operating inconnectiou with a series extending from its rearl of cams er bent arms, ci 2*, tc.,whieh project from that side of a eogged wheel, a, which is nearest tothe main frame of theloom, as seen in Fig. 2, and by dotted lines in Fig. 3. r[here are two bent arms c to each rodvh, &c., the' object of said arms or cams beixg, when the wheel cia isrevolved, to throw the lowerends of the rods hl i* k2 Z" forward in regular and proper succession and far enough to carry the hook of each under the projection or bent end t of the levers", so that when said lever is depressed the said projection, acting upon the Asaid hook, shall vitt the same time depress the arm of the. 'bent lever e2 (hereinbefore dey scribed) to which it maybe hung and thereby cause the opposite arm of said bent lever to pull upon its picker-staff strap and operate the picker-stati` or cause its lower end to advan'ce toward the lay.v Each pickerstaif is drawn back or away from the lay by a spring, j, properly applied to it, :is seen in 'the draw ings. I

The order in which the shuttlesa're to be thrown, varies according to the fabric to be wrought, and by transposiug the ben-t `arms z z a corresponding change will be effected. The cogged wheel a is revolved by atoothed pinion, b",xed upon the end of a horizontal shaft, cf. (See Figs. 1 and 5.) The said shaft has another eogged wheel, dii-fixed upon it, which engages with a eogged pinion, e, on the shaft z, before described. lConsequently when the shaft .e is revolved motion will be imparted by its pinion e to the wheel da and shaft c. v

The next portion of'the mechanism to ,ber described is that by which the driving-beltis moved from 'the fast pulley G toward the loose s pulley H of the driving-shaft in order to stop the operation of the loom whenever, during the passage of any of the shuttles from one series of their boxes or receptacles 'to another, its weft;thread may break, or to efleet the same whenever a shuttle thrown out-of one boXon one side of the loom is not .properly received into its other box or receptacle upon the opposite side thereof.

In Fig. lahorizoutalshaft, y, is represented as extending'aeross the front part ot the loom and being supported by bearings at ys* zi The said shaft has a bent arm, a", xed"upon its left end, which armis shaped and extended in front of'the shifting-lever I,- as exhibited in the drawings. The upper arm ofthe shifting lever passes through a horizontal plate, b5, projecting from the loom-frame. A top view ofthe said plat-e is represented in Fig. 17, in which (fi-denotes a passage formed or made through the said plate for the lever I to pass through and movein4 'lhere is a small shoulder or notch, d", cut. or formed in the front side of -the said passage. 'lhe upper arm of the shifting-lever is to be thrown toward the right and rest against the said shoulder or i notch whenever the loom is to be put iu action, the position'ot said lever. being main- 4tained-jby said ,notch while the loomA is in aetion.4

T' The said shifting-lever has a spring, c5,

` applied toits lower arm and the frame of the and made to act-upon it so as to always 41001.11. rawfitsffork or lo'wenarm toward the loom- Trame.' Consequently whenever the lupper i arm of'theV saidleveris thrown out of the notch di thelower arm thereof will ybe ldrawn n 'toward'theloom-frame, or from being directly in frontof the fast pulley G into beingrdirectly..

as it is acomm'on and-well-.known mechanical device for'changingthe driving-belt from one The arm a is pressed against the shifting-lever by the action of a helical'spring, f 5, properly applied to it. Near the' right end of the shaft y* a small arm, g,

projects downward from said shaft, asseen in Figs. land 5. To the lower end of the said arm a rod,.= isjointed, and is also jointed to a small sectoral lever, is, arranged so as to vibrate back and forth upon a center pin, m5, as

seenin Fig. 5.v rf I plays vertically upon a pin, li, projecting' Fig. 18denotcsa toral lever i and hook ki over it. The said hook Vis jointedfto the frame of the1oom,- or

therefrom. It is arranged directly over and f so that its hooked end shall rest upon thesecf toral lever, andgengages with -a notch, n, made in the top of the carved top part of-said sectoral lever, as seen in Fig. 18. Fig. 19 de- I notes a top viewof said hook and other parts of the lay and between the vibrating Vshuttle-l 4box frames. i Fig. 20 is ajear elevation of the connected .with it, which are situated in rear same'. `A long horizontal shaft, of', extends across the'loom in front of the catch orhook "e k, as seenin Figs. 19 vand v20. It has an arm, l5,

projecting from it, as seen in Figs. 1 9 and 20, the said arm extending under a small projection, qa, from the side of the catch or hook ki. Two ibrk's,1",shaped as seen in Figs.5and 19,arese cured to and project .from the shaft 0' near each cndof the reed-frame s'" of the lay, as seen in 'th'e'drawingsryThe shaft o has another arm, Qt, extending downward from it in the position form as seen in Figs. 5 and 19..

The saidcam 'v5 shouldfbe so pcd that `by itsaction-.on vthe arm t? itwill elevate the. forks r to such height above the plates lf'masto allow a. shuttle, when thrown kfrom one side of the loom toward theother .i1 side thereof, .to freely pass under them, (the, y A orkDOx bet/Weer) them and the plates'lu.

Should 'the shuttle during its passage from one shnttle-box to` another deposit no fthread upon the plates .E mand'in the' thread ol' the warp, the forks will fall into the slots, and when' this takesplace the arm l5 should be .so adjusted as to-meet the projection of the hook or'catch It5 and lift the said catch out of the notch nf of the sectoral arm. While the hook ks is in the. notch n5 it prevents the arm a5, through the action of 'the spring throwing the shifting-lever I 'out of t .notch "n; but'as soon as the hook is elevated ont of the notch the spring ff is released and presses the arm a5 against the shifting-lever and expels it from the notch, and thus permits the spring e5 to draw the lower end or fork. of the `and thus thereby change or move the driving baud or'belt from the fast pulley to and upon the loose one.

The mechanism last described is a common and well-known stop-motion. part of my'invention; but as certain other maof the hook or catch ki", before described. The

A top view of' ward or toward the front of "Fir arm, l", extends upward from each shaft i?, land so that its upper end shall be j ust xin rear of the end of one of a series lof springiplates'm6 m. Fig. 23 denotes va horizontal or nearly horizontal section taken through the top of the arm l and the shutt1e-boxes of the two series in front andrear of it. Each shuttle-box of the tw'o front land't'wo rear series is provided with a shuttle-binder, m", shaped in horizontal sections, as seenl in Fig. 23. Each of the said shuttle-binders is hinged at one end to the shuttle box or frame, which makes part of it. It is placed in a rectangular aperture, n, cut or formed through the side of the shuttie-box, as seen in Fig. 24, which represents. the rear side of one of the shuttle-boxes, ora portion of the plate z" composing it, having the aperture n tbrmedthroughfit and without the shuttle binder vapplied to it. VThe binders m' are forced towardfthe interior' of their respective shuttleboxes by springs'o.6 o", 8vo., Fig. 2, each binder mH being provid-ed 4with a spring, whichy has one end secured to the shuttle-box and the otherrestiug and pressing against the binder m6. 'Each plate m hasits front face shaped to a very obtuse angle, and projects into the interior of the'shuttle-box, as seen at p in Fig. 23. Vheuever'a shuttle is thrown into one 'ofthe shuttle-boxes of either l.

of the two kfront series thereof, it comes into contact withthe angular part pi o'f the shuttlebinder, which projects into the box, and as said angular part is made to, project into the box or path of the shuttle,- and' the shuttle is calculated inits width to correspond as nearly as may be with the width of the vboxwhich receives it, it (the shuttle) will' force :back-f or move the binder m out of its way, and by so doing cause the said spring-plate to .bear'agaiust the top of the arm l, and thereby turn the shaft z' a little in its bearings and so astomove the top of the arm 'gs alittle rearward or in a direction toward the shaft wi., kThe shaft is should have a spring, q, applied toit and the rail v or -s in such manner as to operate upon the shaft and carry or move. thetop of the arm g forward or away fromthe shaftw5 whenever the shuttle leaves the shuttle-box,

or while there is no shuttle in said shuttlebox. Each of the rear series of shuttle-boxes has its shuttle-binder, as seen atm, in the section thereofv in Fig. 23. The said shuttlebinders operate against an arm, 15, which pro-` jects upward from a shaft, k, and is arranged thereon as seen. in Fig. 2, ythe top or upper part of said arm W being exhibited iu Fig. 23. When a shuttle is thrown into one of the rear shuttle-boxes it presses the shuttle-binder m of said shuttle-box forward or in a direction toward the front of the lay. Consequently said plate ms in the samel direction and will turn lthe shaft k a little in its bearings, and' thereby move the top part of the arm h 'fori the loom. -The cam c' should be concentric, with the exception of an angular depression, s, the said an- ,shuttle-box of gular depression being suitable to allow the arm as to descend far enough to cause the arm g5 to rise upward and bear against the pin z5 `and throw the hook or catch R5 out of the notch g n of the sectoral arm, before described. The

thejloomto another on the opposite sidey thereof, the arm a should be prevented from falling so; far as to raise the catch R5 out ofthe notch n andthereby stop the loom from operating. It is for thispurpose that I employ .the arm d6, with itsliprojections elf, to act in conjunc'tionwith the upright arms gf* hfi of the lshaftsf k, before described.

, They peculiar manner in which said parts of themechanism ou each side of-the loom operate in connection with one another I shall now proceed to explain.

It Ahasbeeu hereinbefore specified that the vibrating shuttlebox frames V.s t and u fv are each vibrated or alternately moved first in one direction and tbfi in its opposite.` While a front series is in range with the race-beam ofthe lay another of the back ,series at the opposite end of the loom` is also .in range with the said race-beam. lOne of the projections eef of each arm d@ should be so adjusted upon the arm that when either one ot' the front series ot shuttle-boxes receives a ,shuttle it (the projection) shall, on the fall of the arm di, which takes place when the roll of` the arm a6 descends into the dep ression-s",come directly over and rest upon 'the topof the arm y, belonging to the shaft i of the shuttle-box i V- This deposit of v the 4arm shouldv vtake place as soon as the shuttle has fairly andv 5,

which receives the shuttle. the projection on the top of fully Entered the shuttle-box, and by so doing pressed against the shuttlcbinder m6 of said shuttle-box; and moved the sameas before described,.and in consequence thereof produced a slight 4rearward movementof the arm g ofv the shaft 6, as hereinbefore described. -By

said rearward movement of the arm "g", lorv its upper part, it should be brought intoa cor rect position to receive the projectionnfrom the arm d6,

shaft w from pressing againstthe pin z5, so as to raise the hook orcatchk5 out of the notch ns, and thereby cause a stoppage of theloom..

The said )roection from the arm d should?.v the toppart of the arm-7-6 will be moved by. l J be so adjusted to the top of the arm g, withwhich, it operates, 'that whenever a' shpttle, when thrown, fails to enter the shuttle-box and the arm d descends it (the projection) :shall not meet the armg, which in this case experiences no movement arising from the action of the shuttle against the bindernof the shuttle and when the saidprojecti'on so i' j rests upon thetop of said arm the arm should. be long enough to preventthe arm y of theA Y projection from the end to end of it, shall make an acute angle which the springlle'ver. 1f' moves, the saidver.-

Apressure against the hook, the said pressure :passes down the depression of the cam es.

said lever should be made as a spring,

v:being also arranged in such shuttles to which box, but pass below its top, and by so doing permit the arm 'y5 to be borne 'upward against the pin z5 of the hook or catch k", and thus by being produced by the weight of the arm a6, cause the elevation of the hook out of the catch ni', and of course the immediate stoppage of the loom.

From the above it will be seen that if thel shuttle, when thrown, does not fully and prop-` erly enter the shuttle-boxes of the front series no movement of the arm g" takes place; or, in other words, the said arm is not moved into a position necessary to receive upon its top the arm d when said arm descends during the time the roll of the arm a6 Each of the other projections upon the two arms d should be similarly adjusted and adapted to operate in connection with the arm h adjacent to it when either of the rear series of shuttleboxes immediately adjacent to said projection and said arm h is in range of the race beam and in the act of receiving a shuttle.

That position of the loom which relates to the arrest of the shuttle when it has arrived at a certain position in oneof the shuttle-boxes of one of the series which moves up and down and allows the picker to free itself from the pointed end of the said shuttle, so that the picker may present no impediment to the movement ofthe series of shuttle-loxes, either upward or downward, is as follows: Each of the front Vseries of shuttle-boxes has a springlever, a, Figs. 1, 3,'4, applied to its vibrating frame andV moving upon a pin or fnlcrum, y, projecting therefrom in the position denoted by the drawings. The upper part or arm of and at its upper end should be placed in such a position as to admit of the picker being forced against it whenever the said picker is struck by a shuttle on entering one of the shuttleboxes. The lower end of the spring -lever should be inserted ina vertical groove or elongated passage of a guide-cup, z". A top view of this guide-cup is exhibited Ain Fig. 25, and avertical, central, and longitudinal section of it in Fig. 26. The elongated passage is represented in said figure at a7. The said guidecup should be bolted or fastened upon the door upon which the loom stands and in such a position that a vertical plane passing through the central part of the passage al, and from with the' vertical plane passing through and` in line of the axis .of the fulerum or pin upon tical plane being parallel to either end of the main frame of thel loom, the said guidecup manner that its rear end shall be a distance from thc said end of the frame of the loom greater' than that of its front end therefrom. Such an'arrangement of the guide-cup will, when the front series of it is immediately adjacent retreats in order to receive a shuttle'from the opposite part of the loom, cause the lowerv end of the spring-lever ai* to be moved in such a manner as to carry the upper end ot' the sai spring-lever in a direction toward the lay. Consequently when the shuttle is thrown into the shuttle-box the picker will be forced by it against the upper part of the spring-lever, which will 'constitute a stop, as it were, to arrest the further progress of the shuttle. Vhen the shuttle-boxes advance so as to bring one of the rear series of shuttle-boxes into range with the race-beam, the passage ai of the guide-cup z, spring-lever to advance toward the end of the lay as the said end passes or moves through the said passage. retreat of the upper end of the spring-lever, or amovement of it away in consequence thereof will allow the spring which causes the picker-stati` to retreat after each throw of a shuttle to act upon the pickerstaff and the picker in such manner as to move the picker upon its supports or rods and a short distance away from the end of the shuttle, entirely cl'ear the end of the shuttle 'when the series of shuttle-boxes are moved upward or downward from the picker, thereby preventing any rupture of any part of the machinery which might occur by reason of the point of -the shuttle beigg in too close contact or proximity with the picker when the shuttle-boxes are moved either upward or downward. l

It is well-known that after the picker has been a short time in action the pointed end of the shuttle makes an indentation in it, and as said pointed end might extend too far within the said indentation, required to move the shuttle-boxes upward or downward it becomes necessary' to move the picker far enough away from the point of the shuttle to admit of the shuttleboxes without accident.

In order that the manner in which the spring attached to the picker-stiiitactuates the picker lor forces it away from the shuttle whenever the shuttle-frames advance or come forward may be understood, IA have in Figs. l, 2, 3 represented a picker and its mode of connection with the picker-staff. In said iigurest denotes the picker, which is connected with the picker-staff .over it by means of astiff strip of iron, ci, which is jointed or hinged to both picker-stall" and picker. Consequently the said spring which causes the retreat of the pickerstaff can act upon the picker through the connecting-strip ci, and move it upon its rods or *supports whenever "-theuppcr part'of the Spring-lever af is moved in a direction away from the picker.

lf desirable, each of the four series-of shuttlc-boxes may be provided with a springlever and guidecup or other mechanical equivalents, for the purpose above described.

In Fig. 2, (ZT dT denote springs iixed io Athe rails s and "c, respectively, and in lregardto the hack shuttle-boxes, seen in the drawlwill cause the lower end of the lhis will Vcause a from t-he picker,and

the said distance being far enough to whenever it should be Aof the elevation or depression thrown into one of the rear shuttle-boxes.

p order to prevent accidents from occurring to to turn or move horizontally upon a piu, ork

guide a shuttle into ings,ithe said springsy being for the `purpose of arresting the progress of a shuttle when The next or succeding part of myinvention consists in certain turning guide-plates applied to certain parts ofthe loom-frame in the loom or atshuttle whenever the latter projects from a shuttle-box. Should theshuttle in its passage into a shuttle-box not fully enter the same, a serious `injury to the loom would be likely to occur, when the vibrating frame s t or u v, by which the shuttle-box may be sustained, should move rearward, as that part of the shuttle which would protrude fromv the x 'would be carried in contact with one of the vertical plates tB u? (see Figs. 1, 19) which project above and at the rearpart ofthe plates Z m. Such contact must either seriously-injure the shuttle or some of the mechanism of-th'e loom. To prevent an accident of this kind from happening, each of the said vertical plates tu should be applied to its plate Z or m in such manner as proper mechanical equivalent, projecting upwardfrom the plate l or m* in the position as seen at o in Figs. 1, 19. A spring, w, is placed in rear of each plate t u and is conlined to the plate l* or m, upon which the movable plate t or u" may be situated. The said spring should be made to bear against the plate t or u which it may be in rear of, and keep it up to its position proper to the shuttle-box, the said position being determined by a small projection or screw-pin, av", which extends downward from the outer end of the plate t or u, and is-made to abut against any suitable part of the plate l* or m* upon which "the plate t or u? may be situated. The turning-pin upon which the plate moves is placed at that end of the said plate which is most distant from the shuttle-boxes immediately adjacent to the plate. The springw,- which acts upon/the be so made and applied I plate t' or u', shoul to the plate as to admit the same to retreat far enough to prevent accident Whenever a shuttle projects from a shuttle-box and is borne against ythe spring-plate by the retreat of the vibrating frame carrying said shuttle- 4box.

What I claim as my invention, "and desire 2. The employment of two series of shift' ing shuttle-boxes on one or both sidesof the lay, hung and operated in separate and independent frames on each side of the lay of the loom, the said boxes being shifted and otherwise operated by machinery receiving motion from 'the loom, or from somefirst or other mover working in unison withthe power-loom, substantially as herein described, and for the purpose specified.

3. Combining with the shipper for stopping the loom when the shuttle' fails to pass through, or the equivalent thereof, a protector for each seriesof shifting shuttle-boxes hung in separate frames independent of the lay,

substantially as described and for the purpose specified.

4. 'In combination with the lay of the loom and shuttle-boxes hung in separate frames independent of the lay, the employmentA of jointed guides, substantially as described, for guiding the shuttles in theirpassageI from the shutt1eboxes to the lay,` and vice versa, and which yield to prevent breaking when the shuttle fails to pass entirely through, substantally as described.
