METHOD OF WEAVING S EAMLESS SIDE POCKETS.
SPECIFICATION forming part of Letters Patent No. 415,159, dated November 12, 1889.
Application filed August 3, 1889.
To aZZ whom it may concern:
Be it known that I, ABRAM D. EMERY, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a certain new and useful Improvement in the Method of Weaving Seamless Side Pockets, of which the following is a full description.
My invention relates to a method of weaving seamless side pockets such as described and claimed in an application filed by me May 31, 1889, Serial No. 312,830, (Case 15.) The pockets referred to are closed top and bottom and on both edges, with the exception of an opening in one edge, and are composed of chain-threads and two distinct weftthreads. The method by which these pockets are made results from a modification of the method of weaving as described in an application filed by me February 28, 1888, Serial No. 265,639. The chain-threads are at all times shed so as to form two paths or openings side by side. Two shuttles with attached weftthreads make simultaneous passages through these openings and in the same direct-ion in the loom, forming the two sides of the pocket or a single fabric of double-weight goods, as the case may be. In forming the closed top and'bottom of the pocket where all the threads are bound together in a single piece of goods the chain-threads at each succeeding shedding are passed from one half or opening to the other in regular order, interlacing the chain-threads around the weft-threads. In weaving the two sides of the pocket the chainthreads are shed to form two paths or openings, as before, but the same two threads form the same opening at each shedding. In other words, the chain is divided into two parts which are simultaneously shed for the passage of two separate weft-threads, thereby forming two separate pieces of the fabric side by side. Throughout the body of the pocket, except at the opening thereof, the shuttles are reversed in position at both sides of the loom, thereby forming a closed tube. The opening of the pocket is formed by returning the shuttles to and from one side of the loom in the same path or side and without reversing. This leaves the fabric forming a three-sided inelosure with an opening on the Serial No. 319,702. (No model.)
fourth side constituting the opening of the pocket.
The sequence of operation is as follows: The chain-threads are first shed to produce the single piece of goods constituting the bottom of the pocket. This series of operation is continued until there is formed a length of each fabric sufficient to form the bottoms of two pockets. Then the chain-threads are shed to form the body of the pocket below the opening, then the part of the pocket containing the opening, and then the body of the pocket above the opening, and then the two sides are woven together again to form the top, and so on, forming an endless chain of pockets. The separate pockets are obtained by cutting across the interlaced portions.
In the accompanying drawings, forming part of this specification, Figures 1, 2, 3,and 4 of Sheet 1 represent the component parts of a loom and show the four sheddings for weaving the two sides or halves into one fabric to close the bottom and top of the pocket. Figs. 5, ('3, 7, and 8 of Sheet 2 represent the four sheddings for weaving the separate sides or halves united at the edges to form a tube. Figs. 0, 10, 11, and 12, Sheet 3, represent the four sheddings for forming that portion of together on one side and are open on the other to form the openingto the pocket. Figs. 13, 1-1, 15, and 16, Sheet 4, are enlarged cross-sections of the four sheddings shown in Figs. 1 to 4, Sheet 1. Figs. 17, 1.8, 19, and 20 of Sheet 4 are enlarged cross-sections of the four sheddings, as shown in Figs. 5, 6, 7, and 8, Sheet 2. Figs. 21, 22, 23, and 21 of Sheet 5 are enlarged crosssections of the four sheddings, as shown in Figs. 9, 10, 11, and 12 of Sheet Fig. 25, Sheet 5, is a draft of the chain-threads in the conventional style. Fig. 26, Sheet 5, shows the manner of threading the chain-threads through the heddles. Fig. 27, Sheet 5, is a plan of the fabric, showing the relative positions of the chain and Weftthreads, looking on the side R of the several views.

edge. Fig. 29, Sheet 5, is a cross-section of the fabric as shown in Fig. 27, looking toward and showing the opening.
To better distinguish the weft-threads in the several positions they assume in the fabric, one is shown shaded and the other plain in all the views.
Referring to Figs. 1 to 12, Sheets 1, 2, and 3, the numerals 1, 2, 3, and 4 indicate the four chain-threads or four series of chainthreads. The chain -threads 1 and 3 are the threads used to form the right-hand side R of the pocket, as shown in the several views. The threads 2 and 4 are the threads used to form the left-hand side of the fabric, or that shown on the side L in the several views. All the chain-threads pass around compensating whip-rollers, as fully explained in an application filed by me May 31, 1889, Serial No. 312,828, (Case 13.) The threads 3 and 4 pass over and under the ends of equalizinglever 25, and threads 1 and 2 pass over and under ends of equalizing-lever 26. The threads 1, 2, 3, and 4 pass between the bending- rollers 23 and 24, which keep the threads forming the outsides of the sheddings at an equal tension, as more fully described by me in the application referred to. The numeral 5 is the shaded weft-thread, and is shown attached to shuttle 7. The numeral 6 is the plain weft-thread, and is shown attached to shuttle 8. The numeral 9 is the reed through which all the chain-threads pass. 10 is the fabric in p'rocessof formation. The series of chain-threads 1 pass through eyes in heddle 11, threads 2 pass through eyes in heddle 12, threads 3 pass through eyes in heddle 13, and threads 4 pass through eyes in heddle 14. It will be understood that the threads 1, 2, 3, and 4 each represents a series of chainthreads extending across the loom. The heddles cords 11 and 12 are connected together and pass over and around large roller 19, which has an oscillating motion imparted to it, such as to place the heddle-eyes in either of the positions desired in shedding. The 0pposite ends of the heddles pass around the smaller roller 21. The bending-roller 22 keeps the heddles 11 in alignment with the top of roller 19, and bending-roller 20 likewise aligns heddles '12 with the bottom of roller 21. The heddles 13 and 14 in like manner at one end pass around the large oscillating roller 15, and at the opposite'end around the small roller 17. The bending-rollers 16 and 18 align the hed- (lles 14, the heddle 13 forming a tangent with both rollers 15 and 17.
Referring now to the operation of these devices, the first step in the method as illus trated in Figs. 1 to 4 is forming the bottom of the pocket, which is substantially weaving a single piece of fabric of double weight goods. Two openings are simultaneously formed in the chain-threads at each shedding, and the two shuttles are simultaneously passed through the same. The chain-threads at succeeding sheddings are passed from the inside of one path or opening to the outside of theother path or opening in regular order across the loom.
Referring more more particularly to Fig. 1, Sheet 1, it will be seen that heddle 13 is at the extremity of its;1notion toward the side R, carrying chain-thread 3 to its extreme position on that side, while heddle 14, which is a continuation of heddle 13, is at the extremity of its motion toward the side L, carrying the chain-thread 4 to its extreme position on that side. The heddles 11 and 12 are in the center of their motion or middle position and carry the chain-threads 1 and 2 to the inside of the two paths or openings. This forms the two paths or openings side by side, and may be termed the first double shedding, with the threads 3 and'4 on the two outsides and threads 1 and 2 on the two insides. The
shuttles are represented as being in the rear boxes, with their attached threads extending from them to the fabric. (Indicated at 10.) The shuttles are driven through the openings, shuttle 7 in the side R and shuttle 8 in the side L, carrying their attached threads from rear to front in their respective sides. The weft-threads are shown in position in enlarged cross-sections, Fig. 13, Sheet 4, where the shaded thread 5 is seen on the side R, between the threads 1 and 3, and thread 6 is on the side L, between the threads 2 and 4. The weft-threads are beaten up and form the first pick. The term pick is here used as indicating the complete layer of weft made up of the weft-thread 5 laid in one half and the weft-thread 6 in the other half. The rollers 15 and 19 are now moved in the direc tion indicated by the arrows in Fig. 1, Sheet 1, to the position as shown in Fig. 2, in which the chain-threads 1, governed by heddle 11, are extended on the side L, and ehain-th reads 2, governed by the heddle 12, are extended on the side R, while the threads 3 and 4, governed by the heddles 13 and 14, are in the center, forming the second double shedding. The shuttles are now turned in the direction indicated by the arrows in Fig. 1 to the position as shown in Fig. 2, Sheet 1, and are driven through this second double shedding from front to rear, shuttle 8 layingthe thread (i in the side R and the shuttle 7 laying the thread 5 in the side L. The threads 5 and 6 are seen in position in Fig. 14, Sheet 4, wherein the shaded thread 5 is on the side L, between the chain-threads 1 and 4, and plain thread 6 is on the side R, between the chain-threads 2 and 3. The weft-threads 5 and 6 are also seen crossed between the chain-thread 1 of side L and 2 of side R, as more particularly explained in an application filed by me February 28, 1888, Serial No. 265,639. The threads being beaten up form the second pick. The rollers 15 and 19 are now moved in the direction indicated by the arrows in Fig. 2 to the position as shown in Fig. 3, Sheet 1, in which the chain -thread 4, governed by heddle 14, is extended on the side R, chainthread 3, governed by the heddle 13, is extended on the side L, while the threads 1 and 2, governed by the heddles 11 and 12, are in the center, forming the third double shedding. The shuttles are now turned in the direction indicated by the arrows in Fig. 2 to the position as shown in Fig. 3, Sheet 1, and are driven through this third double shedding from rear to front. Shuttle 8 lays the thread 6 in' the side L and shuttle 7 lays the thread 5 in the side R. The threads are seen in position in enlarged view, Fig. 15, Sheet 4, wherein the shaded thread 5 is on the side R, between the chain-threads 2 and 4, and the thread 0 is on the side L, between the chainthreads 1 and The weft-threads 5 and 6 are also seen crossed between the threads 1 of side L and 2 of side R on the right-hand side. The threads 5 and 6 being beaten up form the third pick. The rollers 15 and 19 are moved in the direction indicated by the arrows in Fig. 3 to the position as shown in Fig. 4, Sheet 1, in which chain-thread 1, governed by heddle 11., is extended on the side R, and chain-thread 2, governed by heddle 12, is extended on the side L, while the threads 3 and 4 are in the center, forming the fourth double shedding. The shuttles are now turned in the direction indicated by the arrows in Fig. 3 to that shown in Fig. 4, Sheet 1, and are driven through this fourth double shedding from front to rear, shuttle S laying the thread 6 in the side R and shuttle 7 laying the thread 5 in the side L. The threads 5 and O are seen in position in Fig. 16, Sheet 4, wherein the plain thread 6 is on the side R, between the threads 1 and 4, and the shaded thread 5 is on the side L, between the threads 2 and3. The weft-threads 5 and Gare crossed between the threads 1 of side R and 2 of side L on the left-hand side. The threads 5 and 6 beingbeaten up form the fourth pick of weft. The four picks now described complete the sequence of positions of the weft-threads and chain-threads in this part of the process. The chain-threads have passed through all positions and return at the next shedding to their original positions. These sheddings are worked over the requisite number-of times to form asingle fabric of double the length of the bottom of one pocket. The shedding is then modified to form the body of the pocket. Two paths or openings are formed in the chainthreads at each shedding, as before; but the paths or openings are always between the same two given chain-threads or series of chainthreads, so that the chain-threads may be regarded as now existing in two halves, and a weft-thread passing at each flight through each half, there are simultaneously formed two fabrics side by side and united at both edges to form an endless tube by the opera tion of reversing the shuttles at both sides of the loom. Referring now to the fifth shedding, or the first shedding of the formation of the body of the pocket, the rollers 15 and 19 are moved in the direction indicated by the arrows in Fig. 4, Sheet 1, to the position as shown in Fig. 5, Sheet 2, in which the thread 3, governed by the heddle 13, is seen extended on the side R, and chain-thread 4, governed by heddle 14, is seen extended on the side L, while threads 1 and 2, governed by the heddles 11 and 12, are in the center, forming the first double shedding of this se ries. The shuttles are turned in the direction indicated by the arrows in Fig. 4, Sheet 1, to the position as shown in Fig. 5, Sheet 2, and are driven through this first double shedding from rear to front, shuttle 7 laying the thread 5 in the side R and shuttle Slaying the thread 6 in the side L. The threads 5 and Gare seen in position in Fig. 17, Sheet 4, wherein the shaded thread 5 is on the side R, between the heddle 11, is seen extended on the side R,
and chain-thread 2, governed by heddle 12, is extended on the side L, while the threads 3 and 4, governed by the heddles 13 and 14, are in the center, forming the second double sheddingof this series. The shuttles are turned in the direction indicated by the arrows in Fig. 5 to the position as shown in Fig. 6, Sheet 2, and are then driven through this second shedding from front to rear, shuttle 8 laying thread 6 in the side R and shuttle 7 laying the thread 5 in the side L. The threads 5 and 6 are seen in position in enlarged crosssection in Fig. 18, Sheet 4, wherein the plain weft-thread 6 is on the side R, between the chain-threads 1 and 3 and shaded thread 5 is between the threads 2 and 4 on the side L. The threads 5 and 6 are crossed between the chain-threads 1 and 2 on the left-hand side. The threads 5 and (5 being beaten up form the second pick of this series. The rollers 15 and 19 are now moved in the direction indicated by the arrows in Fig. (3 in the position as shown in Fig. 7, Sheet 2,and form the third double shedding, which is the same as the first of this series, as shown in Fig.5, Sheet 2, chain-thread 3 beingextended on the side R and chain-thread 4 extended on the side L, with 1 and 2 in the middle. The shuttles are moved in the direction indicated by the arrows in Fig. 6, and are driven through this third double shedding from rear to front, shuttle 7 laying the thread 5 in the side R and the shuttle 8 carrying the thread 6 in the side L. The threads 5 and (i are seen in position in Fig. 19, wherein the thread 5 is between the threads 3 and 1 on the side R and thread 6 between the threads 4 and 2 on the side L. The threads are crossed between the chain-threads 1 and 2 on the right-hand sidef The threads and 6 being beaten up form the third pick, which is like the first of this series, as shown in Fig. 5, Sheet 2, and in enlarged cross-section Fig. 17, Sheet 4. The rollers and 19 are now moved in the direction indicated by the arrows in Fig. 7 to the position as shown in Fig. 8, and form the fourth double shedding, which is the same as the second of this series, as shown in Fig. 6, Sheet 2. The chainthreads 1, being extended on the side R, the threads 2 are extended on the side L, with threads 3 and 4 in the center. The shuttles are turned in the direction indicated by the arrows in Fig. 7, Sheet 2, and are driven through this fourth double shedding from front to rear, shuttle 8 laying the thread 6 in the side R and the shuttle 7 laying the thread 5 in the side L. The threads are seen in position in Fig. 20, Sheet 4-, wherein the thread 6 is on the side R, between the threads 1 and 3, and the thread 5 is on'the side L, between the threads 2 and 4. The threads 5 and G are also crossed between the threads 1 of side R and 2 of side L on the lefthand side. The threads 5 and 6 being beaten up form the fourth pick, which is like the second of this series, as seen in Fig. 6, Sheet 2, and enlarged view, Fig. 18, Sheet 4. This completes the sequence of operations in weaving the body of the pocket, as the shuttles at the next shedding would be presented to the same openings and from the same side of the loom, the chain-threads forming the openings being also in the same relative position as in the first shedding. This sequence is repeated for the desired number of times necessary to form the body of the pocket,and the sheddingis then changed to form a three-sided inclosure, having an opening at one edge which constitutes the opening of the pocket. It will be observed that throughout the process up to this point the shuttles. have been reversed at both sides of the loom. The shuttles being alternately in the front and rear and being transferred at each passage, it follows that in their passage from front to rear the shuttles always pass on the same side, and in their passage from rear to front they pass on the opposite sides to that in which they passed from front to rear, This will be seen upon examining the views, Figs. 1 to 8, Sheets 1 and 2, and the enlarged cross-sections, Figs. 13 to 20, Sheet 4. The odd sheddings, as shown in Figs. 1,3, 5, and 7 and in enlarged views 13, 15, 17, and 19, are those in which the shuttles pass from rear to front. In these sheddi'ngs the shuttle 7 is on the side R and 8 on the side L. In the even .sheddings, as shown in Figs. 2, 4, 6, and S and in enlarged views 14, 16, 18, and 20, the shuttle 7 is on the side L and 8 on the side R, and these are the sheddings in which the shuttles pass from front to rear. The turning of the shuttles in this manner binds the two sides together at each edge. In the next step in the process the chain-threads are shed as in the lastthat is, in halves, to form two fabricsbut the shuttles are only reversed at one side of the loom. This passes the weft-threads by each at that side of the loom, uniting the two fabrics together, or, more properly, forming a continuous fabric at that side of the loom. The shuttles pass to and from the other side of the loom in the same paths or openings without reversing, forming two selvage edges which constitute the edges of the opening of the pocket. This operation is fully explained in detail in an application filed by me February 28, 1888, Serial No. 265,639.
Referring now to the figures,'the rollers 15 and 19 are now inoved in the direction indicatedby the arrows in Fig. 8, Sheet 2, to the position as shown in Fig. 9, Sheet 3, placing the thread 3 on the side R and thread 4 on the side L and the threads 1 and 2 in the center. This forms the first double shedding of this series, and is like that shown in Fig. 5, Sheet 2, the first of the preceding series. The shuttles are turned in the direction indicated by the arrows in Fig. 8, Sheet2, to the position as shown in Fig. 9, Sheet 3, and are passed through this double shedding from rear to front, shuttle 7 carrying the thread 5 in the side R and shuttle 8 carrying the thread 6 in the side L. The threads 5 and 6 are shown in position in Fig. 21, Sheet 5, wherein the thread 5 is on the side R, between the threads 3 and 1, and the thread 6 is on the side L, between the threads 2 and 4. The threads being beaten up form the first pick of weft of this series, or that in which the open side is formed. The rollers 15 and 19 are nowmoved in the direction indicated by the arrows in Fig. 9 to the position as shown in Fig. 10, Sheet 3, placing the chain-threads 1 on the side R and threads 2 on the side L, with 3 and 4 in the center, and form the second double shedding of this series, which is the same as shown in Fig. 6, Sheet 2. The shuttles are not turned at this point, but return through the same sides just traversed, shuttle 7 carrying the weft-thread 5 in the .side R and shuttle S carrying the weft-thread 6 in the side L from front to rear, carrying the weft-thread 5 around the outer chain-thread 1 of the side R and weft-th read 6 around the chain-thread 2 of the side L, forming two selvages at this point. The threads 5 and 6 are seen in position in the enlarged view, Fig. 22, Sheet 5, wherein the shaded thread 5 is again on the side R, between the chain-threads 1 and 3, and the weft-thread 6 is on the side L, between the threads 2 and 4, which, being beaten up, form the second double pick of this series. The rollers 15 and 19 are now moved in the direction indicated by the arrows in Fig. 10 to the position as shown in Fig. 11, Sheet 3, placing the thread 3 on the side R and 4 on the side L, with 1 and 2 in the center, forming the third double shedding of this series, which is like the third of the preceding series, as shown in Fig. 7, Sheet- 2. The shuttles are turned in the direction indicated by the arrows in Fig. 10 to the position as shown in Fig. 11, and are driven through this third double shedding from rear to front, the sh uttle 8 carrying the thread 6 in the side R and shuttle 7 carrying the thread 5 in the side L, and these are seen in position in enlarged cross-section, Fig. 23, wherein the plain thread 6 is on the side R, between the chain-threads 1 and 3, and thread 5 is on the side L, between the threads 2 and 4.. The threads 5 and 6 are seen crossed between the threads 1 and 2 on the right, binding the two halves together at this point. The threads 5 and 6 are beaten up and form the third pick of this series. The rollers 15 and 19 are now moved in the direction indicated by the arrows in Fig. 11 to the position as shown in Fig. 12, Sheet 3, placing the threads 1 on the side R and 2 on the side L, with the threads 3 and l in the center. This forms the fourth double shedding of this series, which is like the fourth of the preceding series, as shown in Fig. 8, Sheet The shuttles are not turned at this point, but return through the same sides just traversed by them, shuttle 8 laying a thread 6 in the side R and shuttle 7 laying the thread 5 in the side L, as they are seen in position in Fig. 21, Sheet 5, wherein the plain thread 6 is on the side R, between the threads 1 and 3, and the thread 5 is on the side L, between the threads 2 and at, the thread 6 passing around the outer chain-thread 1 of side R and thread 5 passing around the thread 2 of the side L. These threads 5 and 0 being beaten up form the fourth pick of this series, which completes the sequence of operations. The sequence is worked over the requisite numberof times to form the desired length of fabric at this point, when the manipulation for forming the tube is again reverted to for the purpose of forming the closed part of the body of the pocket above or below the opening in the same, as the case may be. Thus the rollers 15 and 19 are moved in the direction indicated by the arrows in Fig. 12, Sheet 3, to the position as shown in Fig. 5, Sheet 2. The shuttles are also turned in the direction, as indicated in Fig. 12 to the position as shown in Fig. 5, and are passed through what is, in fact, the first double shedding of the second series. These sheddings, as shown in Figs. 5 to S of Sheet 2, are worked over the requisite number of times for again forming the tube, as shown and described in the before-mentioned second series, forthe distance required, when the rollers 15 and 19 are moved in the direction indicated by the arrows in Fig. 8 to the position as shown in Fig. 1, Sheet 1, and the first series of sheddings 1 to 4 are worked over the requisite number of times for forming the binding or single piece of cloth-of the length required for binding the two sides together, and the process continued in regular order. The sheddings are worked over in the following order: First series, second series,third series, second series, and then first series. This completes theoperations necessary to form the pocket, when the second is worked over and the order continued.
Fig. 25, Sheet 5, shows the Weave or the order of the lifting the threads as they appear looking on the side R. The small squares having a cross designate the risers, or those chain-threads extended on the side R, and the dots the sinkers, or those threads eX- tended 011 the side L, while the blank spaces are those threads which are at the middle or center between the two outer threads and form the insides of the double sheddings. The numerals 1, 2, 3, and 4 at the top represent the threads as they extend across the loom. From the point A to the point- B are four sheddings of the first series used to bind all the chain-threads around the two Weftthreads. Those represented with the cross are raised or extended on the side R, worked in the following order: 3, 2, 4, and 1. The dots are those depressed or extended on the side L, and are worked in the following order: 4., 1, 3, and 2. The threads tand 3 work in opposite directions together, and 2 and 1 likewise work together. Thus when 4 is up will be down, and when 2 is up 1 will be down, and vice versa. These four shedding-s are those of the first series, as shown in Figs. 1 to 4, Sheet 1. From the pcint B to the point C are twelve sheddings, in which the threads 3 and 1 (shown by the crossed squares) are raised in alternation, and are those used to form the fabric or the half-pocket on the side R, and the threads 2 and 4 (represented by the dots) are those used to form the halfpocket on the side L. These sheddings agree with the positions of the chain-threads in the several sheddings used in the second and third series, as shown in Figs. 5 to 12 of Sheets 2 and 3. The manner of threading or drawing in the chain-threads is shown in Fig. 26, wherein the thread 1 is drawn through heddle 11, thread 2 is drawn through heddle 12, thread 3 through lieddle 13, and thread 4- through heddle 11. The heddles 11 and 12 are connected together, and 13 and 14 like wise connected, as before described.
Fig. 27 is a view of the fabric as formed by working over the several series, as hereinbefore described. At the top is shown the result of the first four picks, as seen in Figs. 1 to 1, Sheet 1; then follow four picks, as made by working over the second series, as seen in Figs. 5 to 8, Sheet 2; then four picks, as made by working over the third series, as seen in Figs. 0 to 12, Sheet 3, and then four picks, as made by again working over the second series, as seen in inFigs. 5 to 8, Sheet 2. The next would be four picks made by working over the first series, as shown in Figs. 1 to 1.
Fig. 28 is a longitudinal section of Fig. 27, looking on the closed or right-hand side of the figure; and Fig. 29 is a like view looking on the partially-open or left side of Fig. 27. It will be seen that the positions assumed by the threads agree in all respects with the positions as specified in connection with the three series of sheddings herei-nbefore described.
I make no claim in this application to the 'method of weaving double-weight fabrics, which is involved in the interweavingof the two sides of the pockets to form the closed tops and bottoms of the same. This method is merely incidental to the method of weaving pockets which is the subject of the present application, and forms the subject of another application filed by me October 7, 1889,
opening j ust traversed by the other, repeating the sheddingand retu rnin g the weft-threads to their original position, and so on, in sequences of four for forming the bottom of the pocket, then continuing the flight and reversal of the weft-threads as before, and in sequences of four, and shedding the chain-threads, so as to form two openings between the same, two chain-threads at all times for forming the body of the pocket, then continuing the shedding as last described, and passing the weftthreads each through one opening twice in succession and then through the other opening twice in succession, the other weft-thread being oppositely placed, then repeating the operation for weaving the body of the pocket, then repeating the operation for weaving the bottom of the pocket, and so on, forming an endless chain of pockets.
In testimony whereof I have hereunto set my hand this 29th day of July, A. D. 1889.
