LOOM FOR WEAVING WITH SHORT WEFTS.

SPECIFICATION forming part of Letters Patent No. 415,723, dated November 26, 1889. Application filed January 23, 1886. Serial No. 189,540. (No model.)

To all whom, it may concern.-

Beit known thatI, IsAAc LINDSLEY, of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Looms for WVeaving with Short \Vefts, of which the following is a specification.

Although some parts of my invention may be applicable to looms in which the weft or filling is let off continuously from a cop or bobbin, yet the improvements that I have made and described herein relate principally to a class of looms that are adapted for weaving short lengths or strips of weft or filling, the shuttle of which looms is provided with opening and closing jaws for seizing the separate single lengths or strips of weft or filling when properly presented; and my invention consists, first, in the construction and combination of parts by which the shuttle in its traverse or flight is caused to move close to the face of the reed in the lay-frame; second, in improved devices for feeding the separate lengths or strips of filling to the jaws of the shuttle; third, in novel means for turning the ends of the lengths or strips of filling over the edge of the line of warp-threads and binding the same therewith in order to form a selvage; fourth,in improved means for preventing backlash in the shuttle movement.

' Figure 1 is a partial front elevation of a loom provided with my'ii'nprovement. Fig. 2 is a partial elevation of the left-hand end of the same. Fig. 3 is a detail elevation of a ,portion of the left-hand end with the fillingfeeding wheel removed for the purpose of illustrating the shuttle-carrier movement. Fig. 4 is a partial plan view of the loom. Figs. 5 to 10, inclusive, are enlarged detail views relating to the shuttle and shuttle-carrier. Figs. 11, 12, and 13 are enlarged detail views illustrating the devices employed to form the selvage. Figs. 14: to 19, inclusive,

are enlarged detail views illustrating the mechanism employed for feeding the separate lengths or strips of filling to the shuttle. Fig. 20 is a detail plan view showing one edge of the web and illustrating the movement of the supplementary thread to form the turned selvage. Fig. 21 is a detail plan view showing the full width of the web and illustrating the movement of the supplementary and warp threads. Fig. is a detail elevation showing t-hereed and the position of the warp and supplementary threads at the forward beat of 5 5 the lay. Fig. 23 is adet'ailelevation showing a vertical section of the supplementary and warp threads of the shed, taken in a line corresponding with an 0c of Fig. 20. Fig. 24 is a side elevation of one of the harnesses of the loom, showing the loops which control the elevation of the outer warp-threads. Fig. 25 is a transverse section of the adjacent harnesses of the loom as taken in the plane of the line 00 :c of Fig. 24, showing them in opposite posit-ions.

In the accompanying drawings, A is the frame of the loom; B, the driving-shaft,upon the end of which is placed the driving-pulley O. The lay R of the loom is operated from the shaft B by means of the cranks E E and the pitmen'F F, as in ordinary looms. Upon the shaft B is also secured the gear G, which engages with the larger gear H, secured to the outer end of the cam-shaft I, and upon the opposite end of the cam-shaft-Iis secured the crank J, from which connection is made to the vibrating segment-gear K by means of the rod L. The segment-gear K is pivoted to the frame A at the point 0, and is also provided with a slot a within which is secured the movable stud b, the movement of which within the slot a will cause a greater or less degree of vibrating movement of the segmen tgear. The shaft M rests at one end in a bearing cl, secured to the frame A, and'at the other end in the separate bearing-standard N, which is secured tothe floor or othersupp'ort, and upon the shaft M is secured the pinion O, which engages with the segment-gear K. Upon the shaft M is also secured the drum P, to the periphery of which the opposite ends of the cord f, which serves to reciprocate the sh uttle-carrier Q, are secured. The cord f passes from one side of the drum 1- upward 5 and over the grooved pulley g, which is secured to the lay-beam R by means of the bracket 71-, thence parallel with the lower side of the beam R to the opposite end of the same and over the grooved pulley i, held in I00 the bracket j; thence reversely to the grooved pulley k, which is secured to the beam by means of the bracket Z; thence downward to the opposite side of the drum P, so that a vibrating movement imparted to the segmentgear K will, through the intervening mechanism, impart a reciprocating movement to the cord f and the attached shuttle-carrier. The shuttle-carrier Q is secured to the cord f by means of the screw-clip m and is made to embrace the beveled edges of the slidepiece S, which is secured to the front side of the lay-beam R, as shown in the detail section, Fig. 8.

At the front side of the shuttle-carrier and inclined thereto, as shown in Fig. 8, is secured the loose grooved pulley n, and above the pulley n and in the same inclined plane are placed the grooved pulleys 0 0, which are securely attached to inclined shafts p, which extend inward over the top of the beam R, and at or near the inner end of each of the shafts p is secured the frusto-conical roller 6, the extreme upper surface of which lies in a horizontal plane, the inclined lower surface of the rollers extending downward into an an gular groove q, made in the upper side of the lay-beam. The shuttle T has a frusto-conical roller 8, the shaft t of which is held in an inclined plane parallel to the plane of the shafts p of the shuttle-carrier, the conical inclination of the periphery of the roller 8 being made to correspond with that of the rollers e. The rollers projects below the bottom plate of the shuttle, and when in operation has a surface bearing upon one or the other of the rollers e and upon the intervening warp-threads, the opposite ends of the shuttle projecting over the shuttle-bearings u u on the carrier, and the said. shuttle being heldv to or against the reed by an overhanging bar U, which is firmly supported by means of the brackets 'v 'v, secured to the lay-beam. The warp-threads in the loom will lie between the frusto-eonical rollers e s e, and also between the bottom plate of the shuttle and the bearings a u, and sufficient room is to be left between the rollers e, s, and e for the unobstructed passage of the warp upon the movement of the shuttle through the shed. To suitable lugs at the ends of the lay-beam R are secured the opposite ends of a cord 7'', which passes around the grooved pulleys 0 n 0, so that as the shuttle-carrier is drawn along the lay the pulleys 0, their shafts 1), and the frustoconical rollers e are caused to revolve, a movement in one direction being imparted to said pulleys, shafts, and rollers as the shuttle-carrier is being drawn from left to right and a movement in the opposite direction as the shuttle-carrier is being drawn from right to left, the pulleys and rollers being so proportioned that as the carrier and shuttle are carried along the lay the surface of the engaging roller 6, and therefore of the roller 5 of the shuttle, will move at a surface rate of speed equivalent to or slightly greater than that of the shuttle-carrier; hence as the resistance of the shuttle in its forward movement is borne mainly by the revolving frusto-conical roller 6 at the rear side of the roller .9 very little deflective friction will be exerted upon the warp during the passage of the shuttle.

Heretofore in looms of this class it has not been considered practicable to employa crankmovement for operating the lay, as in Ol'dI-r nary looms, on account of the liability of the shuttle to leave the reed at the backward movement of the lay, and thus bind the warpthreads between the shuttle and its guides,

so that such looms have only been success-- fully operated by the employment of a cam for operating the lay, whereby when the shuttle is made to pass through the shed the lay is held nearly stationary; but the substitution of a crank for the ordinary cam-movement allows the loom to be operated at a much greater rate of speed,and I am enabled to accomplish this by reason of the conical form and the special arrangement of the rolls 6 s e, which, when in motion, operate to hold the shuttle against the reed at all times in its passage through the shed, and, furthermore, an additional improvement is effected by reason of the downwardinclination of the shafts p of the rollers e e, which causes the grooved pulleys 0 at the outer ends of the shafts p to be entirely below the warp-threads, so that the warp will not be abraded by the forward and backward movement of the said grooved pulleys, as heretofore.

While I have represented my invention as applied to a loom in which the shuttle is positively driven, and have also represented inclined shafts in the line of the axes of the grooved pulleys below the line of the warp, which inclination of the shafts necessitates the employment of frusto-conical rollers in the shuttle-carrier in combination with the corresponding frusto-conical roller reversely set on the shuttle, and as the result of such frusto-conical rollers I compel the shuttle in its traverse to keep up to the face of the reed, yet it is manifest that it is not necessary that the loom should be a positive-motion loom in order to secure the above-mentioned result, for if the shuttle-carrier constructed with conical rollers, as herein shown, were forcibly thrown in its proper track along the lay-beam by a sudden impulse, as the shuttle is thrown in ordinary looms, the same beneficial result in the guidance of the shuttletoward the face of the reed would follow during the flight of the carrier. The shuttle has at its ends the pivoted nipper-j aws V V,which are each closed by means of a spring y, attached to an eye 2, which is located inwardly from the pivotscrew 1), as shown in Fig. 10.

The projecting tails c of the nipping-jaw levers are acted upon to open the jaws preparatory to nipping the presented end of the filling lengths or strips by means of the angularly-formed engaging-arms W \V, which are each adj ustably secured to the workingshaft X by means of a hub cl, made in two parts, which are clamped upon the shaft X by means of suitable screws (1, and are also acted upon to open the jaws for the purpose of releasing the filling-strip as the shuttle leaves the shed of the warp by means of the similar engaging-arms W W, which are also adjustably connected in the same manner to the shaft X. The shaft X is secured to the lay-beam R by means of the hangers e c e, and an intermittent vibrating movement is imparted to the arms IV and \V upon the rocking shaft X in timely relation to the reciprocating movement of the V shuttle 'by means of the double-acting cam Y, located upon the camshaft I, from which operative connection is made with the shaft X, as shown in Fig. 5, by means of the horizontal pivoted lever f, the upright connecting-rod a, and the inwardly-projecting arm g, which is rigidly secured to the shaft X. The lever f is held up against the lower side of the cam Y by means of the spiral springs 7t, secured to each of the engagingarms \V WV, and also to a forwardly-projecting hook 2", secured to the front face of the shuttle guide-bar U, thus operating to draw the arms XV away from the said bar.- The desirable slight adjustment of the rearward movement of the engagingarms W V is effected by means of the screw j and its cl1eck-nut7t",tl1e point of the screw striking against the front face of the shuttle guide-bar U. A filling-feeding wheel A, provided on its periphery with a series of equidistant spring-clips m, is located near each, end of the lay, the feeding-wheel at one end only being shown in the drawings, the opposite wheel and its accessory mechanism being essentially the same in construction and operation. The feedingwheel A is held loosely upon a stud Z, which is securely held in a horizontal position at the upper end of a standard B, which at its lower end is hinged to the floor at the point e To the inner side of the feeding-wheel A is secured the ratchetwheel 01, as shown in Figs. 14 and 15, and a groove 0 is made in the periphery of the feed-wheel to receive the friction-strap p, which isfirmly secured to a fixed support at one end and at the other to a spiral spring q.

At the outer end of the stud Z is secured the loose pendent arm 0-, upon which is pivoted the dog 3, made to engage with the teeth of the ratchet-wheel n by means of the upwardly-acting spring '6. The arm 1" is brought back by means of the spiral spring u, at tached to the outer end of a bent arm e, secured to the movable standard B. The standard Bis provided at one side with a stop-foot w .and with a spring as, which is adapted to hold the standard in its normal upright position. A curved downwardly-projecting arm C is secured to the under side of the end of the lay-beam R, having at its outer end an adj usting-screw y, by means of which the forward movement of the arm r and the dog 5- may be regulated with the required de-' clips of the feeding-wheel is shown enlarged in Figs. 16, 17, and 18, in which a is a but ton-piece provided with a central hole o to receive the screw b and with the transverse end grooves c 0 which are adapted to receive the wire arms cl of the holding-spring. The wire of the holding-spring is bent into two adjoining coils e 6 with a bend of the wire f between them, adapted to be held under the head of the screw 6 which serves to secure the button-piece to the periphery of the wheel. The parallel wire arms d (1 which serve to hold the strips of filling material g 9 as shown in the top view, Fig. 19, are turned upward at their outer ends to facilitate the insertion of the said strips under the same up to the guide-line of the front edge of the button-piece z, with the ends 2' proj ecting inward for a certain distance, so that upon the forward movement of the feedingwheel the said ends may come within the range of the nipping movement of the jaws of the shuttle, as shown in Fig. 19.

In order to secure a uniform certainty of action in nipping the projecting ends of the filling-strips at the feeding-wheel, I provide the buffers 7L projecting forward from the front portion of the opposite ends of the laybeam R, which, by striking against the stud Z or the hub of the ratchet-operating arm 7' at near the close of the forward beat of the lay, will cause the yielding standard B and the attached feeding-wheel to partake of the closing forward movement of the lay, thus allowing the jaws of the shuttle to nip the properly-presented fillingstrip with uniform certainty; and to provide for accidental imperfections in the presented end of the strip I attach the light flat springs a (t to the opposite ends of the lay, so that the forwardlyprojecting wire guides 6 will serve to catch a bent or inclined filling-strip end and guide the same to the proper point for entering the jaws of the shuttle, the back jaw of the shuttle in its forward movement to nip the filling-strip striking against the upper end of the thin upright spring (L to which the outwardly-curved wire guides are attached,

'and forcing the same backward preparatory to seizing the strip, as shown in Fig. 19.

In weaving matting by hand with straw or other similar filling-strips which occur in lengths slightly greater than the width of the woven web it is customary to form asel- I vage by turning the alternate ends of the filling-strips back over the outer warp-thread and under the adjacent inner warp-thread, and in order to thus turn the ends of the filling-strips successfully in a power-loom I arrange the oppositely-directed side cams D D upon the shaft I to operate against the u p right pins or rollers 7' at the curved ends of the horizontal levers E E, pivoted to brackets 10 which are secured to the'inner sides of the end frames of the loom, as shown in Fig. 4. To the rear sides of the lay-swords F F are pivoted the levers G, one of which is shown enlarged in the detail section, Fig.

12, the lower end of the lever G being provided with a perforation adapted to receive the loosely-inserted end of the lever E to form a joint. To the upper end of the lover G is secured the curved downwardly-extending arm Z provided at its lower end with an eye m adapted to receive the supplementary thread 07?, which serves to turn the end of the filling-strip to form the selvage. The eye m and its inclosed thread will thus receive a back-and-forth movement in the direction of the side of the lay from the rotary movement of its operating-cam.

At the upper side of the lay-beam R and adjoining the upward continuation of the swords of the lay is secured the metallic plate u, provided with a perforation, through which is passed the outer warp-thread guide 0, extending downwardly through the laybeam R, and terminating with an attached roller 19 which upon the backward movement of the lay is adapted to engage with the cambar H, pivoted to the bracket g which is secured to the inner side of the end frame A and is provided with a projecting stop-pin 0, which servesto prevent the outer end of the said cam-bar from dropping below its proper point for engagement. The cam-bar H is provided with the incline 0*, adapted for engagement with the roller 19 of the outerwarp thread guide 0 and also with the incline 8 which is adapted for engagement with the upper side of the cross-bar 79, extending between the swords F F of the lay. The wedge form of the cam-bar H will cause the required rapid upward movement of the outer warp-thread guide 0 at the extreme backward movement of the lay. The guide 0 is also placed in line with the front of the reed, and thus serves to beat up the filling-strips between the outer warp-thread o and the laterally-moved supplementary warp-thread 02 The required mechanical operation for alternately turning one end of the filling-strips to form a proper selvage is illustrated in Figs. 20, 21, 22, and 23, Fig. 20 showing an enlarged detail plan View of the right-hand portion of a loosely-woven web, the ends of the fillingstrips 10 being alternately turned over the outer warp-thread '0 by means of the proper up-and-down movement of the said thread and the lateral movement of the adjacent supplementary thread of in timely relation to the passage of the shuttle T through the shed, and in this figure n represents the fillingstrips when properly arranged in the woven web, and a a single filling-strip just at the point of being deposited in the open shed by the opening movement of the jaws of the shuttle. The harnesses b b may be operated by any of the well-known methods for operating loom harnesses; and the outer warpthreads 0 instead of being passed through the ordinary eyes of the harnesses b are made to'pass through open wire loops 0 c, which are secured to the upper bar of the harness and extend downward to the level of the harness -eyes, and by this means the outer warp thread will always be held at the upper side of the shed and upon the backward movement of the lay and opening of the shed the outer warp-thread guide 0 will be raised with the outer warp-thread to the upper side of the shed by the upward action of the pivoted cam H", so that the shuttie-nipped end of the filling-strip u will be brought under the thread "0 while thesupplementary thread n is crossed over the said thread outwardly and held at the lower side of the shed by means of the holding-eye m of the arm Z The relative positions of the outer warpthread 0 and the adjacent supplementary thread 71 in a vertical plane at the backward limit of the movement of the lay are shown in Fig. 23, which shows a vertical section of the warp-threads taken in the line 00 a: of Fig. 20. Upon the succeeding forward beat of the'lay the filling-strip a will be beat into the web, with its end x projecting from the edge of the same, and upon the receding movement of the lay and the reverse opening of the shed the continued revolution of the cam D will cause the eye m and the inclosed threadn to be brought back over the outer warpthread 0 as shown in the detail plan View, Fig. 21, so that at the close of the ensuing forward beat the projecting end 00 of the filling-strip will be fully turned over the outer warp-thread and be firmly held in the web by means of the overlying thread n andin order to properly accomplish this lateral movement of the thread 11 the outer warp-thread guide 0 is arranged to carry the thread o below the general level of the warp at the forward position of the lay, so that the thread n held in the laterally-moving eye m may pass over the outer warp-thread in either direction without obstruction. The supplementary threads of n at opposite sides of the web alternate in their movements back and forth over the outer warp-thread Q72, so that in any case at the forward beat of the lay one of the threads 91 will be held by the eye m outside of the outer warp-thread and the other at the inner side of the same, as shown in Figs. 21 and 22.

From the foregoing detailed description of the mechanism it will be understood that one end of each fillingrstrip is alternately turned these threads do not form over the outermost edge of the line of warps preliminary to being bound with the warps to form a firm selvage, served that this turning over of the ends of the filling-strips is accomplished at each edge of the fabric, respectively,by means of the supplementary warp threads 12?, and that at all times a part of the warp proper, because they do not pass through the reed of the lay-frame nor through the eyes of the harness. They are therefore capable, by reason of this freedom from re straint, of being moved laterally, and as they are respectively upon the under side of the filling-strips, upon the endsof which they are to operate at the time when such filling-strips are inserted in the shed, they are enabled when a lateral movement is given to them toward the center of the fabric by the effect of the inward movement of the guitle eye m i to turn over the projecting end of the fillingstrips, so that it will lie upon the top surface of the fabric. This movement of the supplementary warp-thread 01 having been accomplished, with the result of causing the ends of the filling-strips to be turned over the outer warp-thread proper, the next operation is to cause such supplementary warpthread to become a part of the warp proper, and when the same forms a shed with the warp-threads proper upon the ensuing beat of the lay and movement of the harnesses and another strip of filling has been inserted and beaten upihe former strip of filling, with its turned end, will be firmly held in place. This operation is performed alternately upon each edge of the fabric, so that the flexible tips of each filling-strip inserted from opposite sides of the loom will be turned over and bound, while the other end of each filling-strip will be projecting. After the fabric has been removed from the loom the projecting ends may be trimmed, leaving a firm and true selvage edge to the fabric. I have preferred to cause the outermost warpthreads of the warp proper to spring down ward, in order to give room for the passage of the supplementary warp-thread over the same in performing the ofiice of turning over the ends of the filling-strips, and prefer subsequently to cause such outermost threads to be sprung upward to cross with such supplementary warp-threads to form a shed and hold the turned-over end of the filling-strip; but it is apparent that an upward in addition to its lateral movement could be given to the I supplementary warp'thread, and thus accomplish the same relation of such supplement ary warp-thread to the outermost thread of the warp proper as is now done without changing at all that mode of operation which involves a warp-thread supplementary to the warp proper, and which performs the double office of mechanically turning over the ends of the filling-strips and of subsequently performing the duty of a Warp-thread proper.

In order that the projecting end 11: of the and it will alsobe obfillingstrip a may be prevented from escaping the warp-thread a and thus fail to be properly turned over the outer Warp-thread W, I pivot a light wire arm a at the rear side of the standards b of the reed-bar, the said arm at its outer end being deflected to the front side of the reed, so as to rest lightly upon a number of the warp-threads, and by means of this Wire the projecting end 00 of the filling-strip is prevented from bending laterally, and so does not escape from the warp-thread 11 upon the inward movement of the holding-eye m In order to properly gage the tension of the threads 01 which operate to turn the ends of the filling-strips at each side of the web, I wind the said warp-threads upon separate spools dtand apply to such spools the amount of friction required in any case to produce the tension desired. It is also desirable in looms of this class to provide means for preventing a rebound of the shuttle'carrier mechanism, which would tend to render the nipping-jaws of the shuttle uncertain in their action when seizing the presented end i of the filling-strip, and in order to prevent the backlash of the said mechanism from thus interfering with the proper action of the nipping-jaws I attach a downwardly-extendingspring e to one end of the lay-beam R and provide the lower end of the said spring with a friction-pad f, which at the forward position of the lay, as shown in Figs. 2 and 3, will press firmly against the periphcry of the drum P, thus effectually checking any tendency toward a reverse action of the said drum and shuttle-carrier until the cranks of the driving-shaft B have fully passed the forward center of their action upon the lay: The outer arms \V XV, which operate the forward nipping-jaws of the shuttle, are secured to the rocking shaft X so that their operating-faces will be somewhat in advance of the corresponding faces of the inner arms WV \V, which serve to open the rear jaws in order to drop the filling-strip properly in the shed, and the arms \V and W" are held at their rearward position by means of the cam Y, so that upon the continued forward movement of the'shuttle the arm WV will cause the complete opening of the forward nippingjaws, and then the continued rotary movement of the cam Y will cause movement of the arm \V, so that the forward open jaws of the shuttle will be releasedfrom the pressureof the said arm and will become gradually closed upon the end of the filling-strip preparatory to a reverse movement of the shuttle through the shed.
