To all whom, it ntay concern.

Be i t known that I, GEORGE FRANCIS KUETT,

a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a certain new and following is a specification.

My invention has reference to that type of narrow-ware looms known as needle-looms and it relates more particularly to the fillinginserting needles, which are reciprocated through the warp-sheds to lay the filling therein in the form of loops and to the de vices for holding or carrying and operating said needles. In a loom of this type the reed is usually divided into alarge number ofsec-.

Lions, corresponding to the number of fabrics to be woven at one time, separate weaving devices, including the filling-inserting nee-' dles, being combined with each reed-section; audit is customary to mount all of these fillmg-mserting needles on one long bar or carrier if only one filling-inserting needle be used with each section or on two long bars or carriers if two filling-inserting needles be used with each section, adapted to lay the fillingin the shed from opposite sides thereof either 1 l batten, and thus serves to hold the traversebar to which it is attached securely in place. I Under this arrangement there is no liability I of the traverse-bars to stick or jam, friction r simultaneously or alternately, according as it is desired to lay two filling-loops or one filling-' loop in each pick. Under my invention I curve or bend the filling-inserting needle lengthwise between its ends in a plane transverse to the warps, so that in passing across through the warp-shed it will exercise a wiping or combing action on the warps, thus putting the shed in best condition for work and loosening any ends or strands which may have become entangled and bound together. I find this construction to be very effective for the purpose. The filling-insertingneedlecarriers or traverse-bars usually havcbeen mounted side by side in a raceway or raceways formed in the top of and lengthwise of the batten or lay. Owing to accumulations of dust and refuse and to variations in temperature and hygrometric conditions these bars are apt at times to bind and jam or stick in their raceways, thus rendering it difiicult to operate them. At the same time by frictional contact with the batten and consequent Wear they are apt in time to work loose and to shake and tilt laterally, as well as to lift or rise, in their raceways, thus producing uncertain and sate for wear. from lifting or rising, I mountin the project- 3 ing lower end of each fin an antifriction-roller lorotherlike or suitable antifriction device,

.side shake or tilting is prevented. to reciprocate the traverse-bars, I combine with each of them a lever of the first order, which at one end directly engages an operatj ing-cam, and at a point between its two ends iis fulcrumed to the frame of the loom, so as 1 to vibrate in practically a horizontal plane. This lever engages the traverse-bar by a slotand-pin connection, which will permit the leimperfect action of the filling-inserting needles, which are fast to and move with them.

These defects I entirely obviate by arranging the traverse-bars so that they in effect @simply lie on top of the batten or lay, havuseful Improvement in Looms, of which the j 3 no contact with the batten-except on their under sides, which rest on the batten. lth'e traverse-bars in their movements by 1 means of thin metal fins secured at. intervals te their under sides and projecting downward through slots of suitable length formed in land lengthwise of the batten or lay, these fins not only guiding the carriers in their ing no contact with each other and having I guide longitudinal movements, but also serving as lstays to prevent any lateral vibration or ishake and tilt of said carriers. snugly in the slots in the batten, and at the top and bottom of each I provide a removable I plate, of hard wood or othersuitable material,

which bounds the edges of the slotand can be removed and replaced in order to compen- To prevent this traverse-bar which bears against the bottomof the lay or is reduced to a minimum, and all appreciable In order ver to actuate the traverse-bar, while thelatter is at the same time left free to move with the batten or lay on which itis mounted, and between the fulcrum of the lever and the {point at which it engages the traverse-bar is i a support on which the lever rests and over 1 which it can move, so as to be held practically out of contact with the batten.

The particularloom shown in the dra ings is one in whichthe filling-inserting needles movable lengthwiseof the lay and the reedsections are combined with filling-loop-engaging needles reciprocated in a pathtransverse to that of the filling-inserting needles and. provisions for movingsaidloop-engaging needles toward the reedand the edgeof the warp, as set forth in my Letters Patent No.

653,249. datedJuly 10, 1900. I have, however, omitted to here represent the vertical loop-engaging needles (except in Figs. 9 and 10, where they are shown diagrammatically only) inasmuch as they are unnecessary-to an understanding of my present improvements. For the same reason I have here omitted the tension and take-up devicesof my said patent. The movement of the parts inmy present loom are much the same'as that of those in my said patent. save that'here the traverse-bars move simultaneously, .while there they move alternately. It is merel a matter of adjustment of the operatingvcams to obtain either movement, or, if desired, one traverse-bar obviously may be thrown out of action altogether.

A is the loom-frame. Bis the lay or batten, hung from the frame on lay-swords O. D is the main or drive shaft from a crank E, on

which the lay is oscillated through the inter mediary of a connecting-rod F. G is the breast-beam. All these parts may be of any usual or desired construction.

Mounted on the lay in any usual manner is the reed a which. may be formed in sections corresponding to the number of fabrics desiredto be woven at one time, and mounted erse bars a 61*.

to slide upon and lengthwise of the lay are two filling-inserting-needle carriers or trav- With each reed-section is .combined harness a for forming the warplshed, two-horizontal filling-inserting needles ib-b, secured -to the traverse-bars a (1 respectively, for inserting the fillingl from op- .posite sides or edges of the warp-shed, and two vertically-reciprocating filling-loop engaging needlesc c, Figs. 9 and 10, these ,parts, together with a take-up and tension,

- The warps whichform the shed are shown fatw. One of-thefilling-inserting.needles in this instancev the needle b -1-is curved or bent lengthwise between its ends in: a plane transverse to the warps, as shown more particularly in Figs. 6, 7, and 10, the bend being in this instance. downward and toward the under warps of the shed. By thus forming the needle its bellying portion when the needle traverses the'shed wipes over and depresses the under warps and exercises a combing action thereon, which-is very effective to separate and. loosen such strands as .may have become entangled or bound together by loose filaments and fibers and to ,putthe warps in thebest condition for work. The traverse-bars a. a are placed upon the top of the lay B, preferably in a lon- .gitudinalrecess or notch B formed in the topof the lay at. its; edge which faces or is nearest to "the reed, so that their tops shall .be about fiushwith the top of the lay. They lie in this recess, resting upon the bottom of the recess, but having no contact either with :the side of the recess orwith each other. To 'guide' them in their movements, each traverse-bar is provided at intervals throughout its length with downwardly-projecting fiat strips or fins f, of. metal or other suitable material, which extend through slots d, extending vertically through the lay and of a length sufficient to permit the bars to have the requisite traverse movement. These slots at top and bottom are'provided with slotted scutcheons or plates 6, which are let into and removably secured to the lay, as shown in Figs. 4, 6, 7,.and 8. These scutcheons are made of a hard substance, which will resist wear. I find; boxwood verysuitable for this purpose; but any other substance or material may be used. The slots in them are of a width to fit the fins f without undue friction, but closely enough to prevent appreciable lateralplay. The slot in the body of the lay between the top and,bottom scutcheons need not fit the fin accuratelyg-nor, in-

deed, need its sideshave contact with the fin. In this way I obtain for the traverse- Ibars, with minimum friction, along and extended bearing in a vertical sense, which will efiectually prevent any lateral shakeor tilting of the bars during their reciprocatory movement, thus rendering the needles I) b most accurate and precise in their action. The object of making thescutcheons e removable is to permit any one which becomes worn or damaged to be removed and replaced by a fresh one. The lower end of the fin, which projects down through and beyond the bottom scutcheon, is slotted, so as to have a .yoke form, as seen -in Figs. 5 and 6, and in this yoke is removably secured, by means of:

a set-nut g the axle g of an antifrictionroller g, which latter, as seen in Figs. 6 and S, bears upon the under side or bottom of the lay, and thus serves to hold the traversebar, to which it pertains, downin placeduring its reciprocatory movement. The fins f without these antifriction-rollers would still imparting movement to the traverse-bars,

said mechanism being fully shown in Figs. 1, 2, and These bars are reciprocated by means of levers M M, each of which at one, end engages its appropriate traverse-bar a" or (1?, at the other end engages its appropriate operating-cam J or K, and, at a point between its ends is fulcrumed or pivoted to the frame of the loom or to some part attached thereto, the fulcrum or pivot pin being shown at m. The cams J K are fast on a shaft L, which is driven from crank-shaft D through gearing H I. In the present instance the cams by adjustment are so timed as to reciprocate the traverse-bars a a simultaneously in opposite directions, thus causing two filling-loops to be laid in the shed simultaneously from opposite sides of the warpshed at each reciprocation; but, as hereinbefore stated, it is obvious that by adjustment of the cams the traverse-bars may be made to reciprocate alternately, or one of the bars might be thrown out of operation altogether. Each lever directly engages its traverse-bar by a pin-and-slot connection, each bar having secured to it a vertical pin h, (ha-ving on it a roller-sleeve h to reduce friction,) which enters a longitudinal slot 'iin the front arm of the lever. In this way the lever can reciprocate the traverse-bar,while at the same time the latter is left free to oscillate back and forth with the lay on which it is mounted. The front arms or ends of the leversM have no contact whatever with the lay. They are held above and out of contact therewith, for this purpose resting upon and moving overthe face of a supporting-frame N, secured to the frame v A of the loom. This supporting-frame,which carries the levers, isniounted andheld upon an axle or fixed shaft N, secured to the frame .A, Fig. 3, bcing'held to'said shaft'oraxleby aset-srrew n, by loosening which the frame N can betilted on the shaft Nasan axis, so as to accurately adjust the connections of each lever with its traversebar and it-soperating-cam, respectively. Each level-engages its operating-cam through the intermediary of an antifriction-roller pin 19, which enters the peripheral cam-groove in the cam. This .pin 13 isyertically over the axis of revolution of the cam, or, in other words, is situated in a plane which passes longitudinally through the axis of the revolution of the cam and is at right angles with the plane of oscillation of the lever. t

For each lever M there is a fulcrum-plate N ,'through which and the lever passes the fulcrum or pivot pin on. Each plate N is mounted upon the axle or fixed shaft N and is held thereon by a set-screw in the same way as the supporting-frame N, already referred to and as is illustrated clearly in Fig. 3. The fulcrum or pivot pin m has on it a boss m,interposed between the fulcrum-plate and thelever,so as to hold the two out of contact, and thus reduce friction and wear.

It is desirable to vary the throw of the front ends of the lever, and consequently the extent of traverse movement of each traversebar, to accord with the width of fabric to be woven in the loom. This can be done by varying the leverage or the relative length of the two arms of the lever. It is essential, however, that this should be done without change in the position of the pin 13 with respect to its operating-cam, and to effect this result I provide for shifting the position of the fulcrum or pivot. m lengthwise of the leleverin the following way: In and lengthwise of the fulcrum-plate N is formed a series of holes to and in the lever M is formed a corresponding series of holes 0, which register with holes 02. The fulcrum or pivot m is made removable, so thatit may be shifted from one hole to another, and thus the leverage can be varied; but as the pivot is removable it will be liable to work loose and to shake or tilt, thus rendering the action of the lever uncertain. To remedy this and to hold the pivotpin absolutely steady in whatever position it may be placed, I provide a steady-plate P, having in it three holes 19 20 0, the central one,p, having a raised hub 19 being for the fulcrum-pin mand the two end holes forthe reception of steady pins or bolts r. The holes 19 19 p are equally spaced apart, and the holes of each of the series 0 and n are correspondingly spaced. Thus when the fulcrum-pin passing through the central hole 19 is in one set of holes a 0 in the lever and fulcrumplate the holes 19 p for the steady-bolts r will each be over and in register with a corresponding hole in the lever below. The bolts when in place are secured by nuts 7, which bind the steady-plate fast to the lever, and this plate by the hole p furnishes an elongated bearing forthe lever upon the fulcrum- 'IIO pin, which is adj-nstable with the remiumpin. The 'fulcrum-pin is secured by'a nut m on its screw threaded lowerendbelowthe-' fulcrum plate. N and by'a ,cotter' pin m inji; its upper end,,-- which projects abOVe'the hub' 10 .015 the steady-plate. In lieu-of curving or bending 'the bodyofi the needle, as hereinbefore provided, theii same result obviously may be securedin other "ways, what is essential being that "the inee-f dlesshould be provided with a projecting; part arranged and adapted'to wipe overiorif upon the warpsduring the traverse of the; needle :through the warp-shed, and I-IdeSi-rei to be understood as including anysuc'h ob-f vious modification in my claim.
