UNITED STATES PATENT 'OEEIcEi ABRAM D. EMERY, OF TAUNTON, MASSACHUSETTS. Y
'y wovEN FABRIC.
SPECIFICATION forming part of Letters Patent No. 415,142, dated November 12, 1889.
Application filed May 18, 1888. Serial No. 274.257. (No specimens.)
To all whom it may concern;
Be itknown that I, ABRAM Dl EMERY, a citi- Zen of the United States, and a resident of Taunton, in the county of Bristol and State of Massachusetts, have invented a certain new and useful Improved Woven Fabric, of which the fpllowing is a specification.
My invention relates to plain one-ply woven Vfabrics composed of a single set of chainthreads and two distinct weft-threads, which cross the chain-threads in such a manner that each weft-thread occupies only a portion of each shedding, the weft-threads being transferred to the next succeeding shedding at or near the center of the fabric, as more broadly setforth and claimed in an application filed by me February 28,v 1888, Serial No. 265,581. In that. application my invention was illustrated specifically by a fabric in which the weft-threads are transferred at the center of the fabric about a chain-thread at or near the center, the weft-threads crossing each other over and under that chain-thread, the position of the weft-threads of over and under being reversed ateach transfer.
According to my present invention, which is a modification of the general invention in rcspectto the relation of the weft-threads to the chain-threads at the center, the weftthreads are transferred to a succeeding shedding at or near the center about two adjoining chain-threads, which are always between them, the weft-threads crossing each other at one transfer over and under the said two chainthreads and crossing each other at the next transfer between the two chain-threads, as more broadly described and claimed in applications filed by me May 18, 1888, Serial Nos. 274,256 and 274,258.
In the accompanying drawing, forming a portion of this specification, the figure is a plan view of a fabric embodying my present invention with the threads separated and enlarged.
1 indicates one of the weft-threads, which is shown as shaded in color, and 2 indicates the other weft-thread, which is shown as plain in color for the purpose of facilitating the description.
3 and L,Lindicate the adjoining chain-threads at the center, which are always between the weft-threads in transferring. The remaining chain-threads, (indicated by the numerals 5 and 6) are arranged in the usual mannerin sequences of two, passing alternately over and under the weft-threads throughout the length and breadth of the fabric.
The fabric thus illustrated corresponds in all respects, except in the particulars hereinbefore mentioned, with the fabric illustrated 6o and described in the applications filed May 18, 1888, Serial Nos. 274,256 and 274,258, before referred'to.
The threads are disposed, generally speaking, in the following manner: Each pick is made up of two distinct weft-threads, one of which fills one half of the path in any given shedding and the other the otherhalf. Thus the first pick (shown in the lower half of the figure) is composed of the shaded thread 1 7o on the right and the plain thread 2 on the left hand side of the center. The next pick is composed of the same two threads, occupying adjoining portions of the shedding, as before, but placed in opposite parts of the fab'- 75 ric by reason of having passed by each other Y at the center. The third pick is likewise made up of the' same two threads placed in the same parts of the fabric as in the second pick. `In the fourth pick the threads pass 8o each other again -at the center and cross over to opposite parts of the fabric, as in the first pick described. At the fth pick the threads are all disposed as in the first pick,
the sequence being completed every four picks. In other words, the fabric is composed of a set of chain-threads and two distinct weft-threads, which occupy contiguous parts of each shedding in opposite parts of the fabric, and in which the threads occupy 9o the same relative positions in the fabric for two successive picks-that is to say,lthe weftthreads will lie on the right-hand and lefthand side, respectively, of the center of the fabric for two sheddings or picks, and will then exchange positions for two successive picks, and then exchange back into their original position in the fabric for two successive picks, and so on. Each weft-thread will thus make two passages through one half of the 10o fabric and then two passages through the opposite half of the fabric, each pick being` through a succeeding shedding. From this description it will be apparent that the weftthreads are arranged in sequences of four that is to say, each \\'eft-thre.ul will return to its original position every fifth pick, and the weft-threads are always oppositely placed, so that when one is on the left of the center the other is on the right of the center, and the threads reverse their positions in this respect every two picks. l `urthermore, the weftthreads in being transferred to a succeeding shedding` at or near the center of the fabric pass one over and one under the two adjoining chain-threads 3 and i, crossing eachother in their passage, but at one transfer. The weft-thread which passes overthe two adj ein* ing chain-threiuls crosses over the other weftlhread, and the weft-thread which passes under the two chainithrez'uls crosses under the other weft-thread, while at the next transfer the weftthread which passes over the two chain-threads crosses under the other weftthread at a point between the two chainthreads, the other weft-thread occupying the opposite relation to the chain-thre`ads and the first weft-thread. These two styles of transfer may be termed, for the purposes of this specification, a lon g cross anda short cross,7 the first being the transfer where the two weft-threads cross each other over and under two adjoining cliaiittlireads, and the second being a transfer where the threads cross each other between the two adjoining chain-threads. Thus in the first transfer or long cross (shown in the lower part of the figure) the shaded thread l, passes over the chainthreads and 4, crossing over the plain thread 2 in its passage, the plain thread 2 passing .under the two chain-threads 3 and t and under the shaded thread 1. At the next transfer, illustrating' the short cross, the shaded thread 1 passes under the two chain-threads, crossing over the weft-thread 2 between the chain-threads, while the plain thread 2 crosses over the two chain-threads and under the shaded thread 1 between the two chainthreads, thus forming a short cross or lock separating the two chain-threads. The third transfer shown is a reproduction of the first, so that the sequence of the weft-threads is completed in all respects every four picks. It will also be observed that the weft-threads are alternately over and under the two ad- Qioining chainthreads,while the shaded thread 1 always crosses over the plain thread 2, at one transfer crossing over the two chainthreads, making a long cross, and at thenext transfer passing under the twochain-threads and crossin g over the other weft-thread, making a short cross, and so on. The weft-threzul approaching the center from the right always passes over the two, chain-threads, while the weft-th read approachin the center from the left of the fabric always passes under the two chainthreadsltwill be understood of course that the position of the threads in this respect might be reversed without altering the essential characteristics of the fabric, the thread being shown shaded in the drawing merely to facilitate the description, as explained. Assuming that the weft-threads 1 and 2, as shown in the first pick, approach the center from the right and left hand side of the ligure, respectively, and pass over into the opposite halves of the fabric, crossing cach other, and are then returned again toward the center, it will be observed that the long cross is formed when the shaded thread 1 approaches the center from the right and the plain thread 2 approaches the center from the left, while the short cross is formed when the shaded thread 1 approaches the center `from the left and the plain thread 2 approaches the center from the right. It will be understood of course that the position of the threads in this respect might be reversed without altering the essential character of the fabric,
lt will of course be understood that my invention is not limited to fabrics in which the weft-threads are transferred and crossed about the center chain-threads. This is the usual and convenient form, made hy running t-he loom atits full capacity; but, as explained in the applications filed by me May 18, 1888, Serial Nos. 274,256 and 274,258, the two parts of the fabric may be of unequal breadth, my invention in this respect consisting, as described, of transferring the weft-threads into a succeeding shedding at a point between the two selvage edges.
The fabric herein described and claimed is made bythe method of manufacture fully eX- plained in my applications, Serial No. 265,636, filed February 28, 1888, and Serial No. 274,259, filed May 18, 1888; and I make no claim in this application to such methods of manufacture.
That I cla-iin as my invention isl. As a new article of manufacture, aplain one-ply fabric composed of a single set of ehain-threads and two distinct weft-threads which are transferred at or near the cent-er of the fabric from one pick into a succeeding pick and into opposite positions in the fabric about two adjoining chain-threads which are always between them, making along cross at one transfer and making a short cross at the next transfer, and so on alternately.
2. As a new article of manufacture, a plain one-pl y fabric composed of a' single set of chain-threads and two distinct weft-threads which are transferred at or near the center of lthe fabric from one pick into a succeeding pick and into opposite positions in the fabric about two adjoining chain-threads which are always between them, making a long cross and a short cross alternately, the relation of the weft-threads to the chain-threads of over and under being reversed at each transfer.
o. As a new article of manufacture, aplain one-ply fabric composed of a single set of clniiilrtlireads and two distinct weft-threads which are transferred at or near the center of IDD IIO
the fabric from one pick into a succeeding pick and into opposite positions in the fabric about two adjoining chain-threads which are always between them, making a long cross and a short cross alternately, with one weftthread uniformly crossing over the other.
4. As a new article of manufacture, a plain one-ply fabric composed of Va single set of chain-threads and two distinct weft-threads which are transferred at or near the center of the fabric from one pick into a succeeding pick and into opposite -positions in the fabric, making a long cross when a given thread approaches the center of the fabric from a given side and making a short cross when the same thread approaches the center of the fabric from the opposite side.
5. As a new article of manufacture, a plain one-ply fabric composed of a single set of Cil chain-threads and two distinct weft-threads which are transferred at or near the center. of the fabric from one pick into a succeeding pick and. into opposite posit-ions in the fabric.` passing alternately over and under two adjoining chain-threads which are always between lchem, making a long cross over and under said chain-threads at one transfer and a short cross between said chain-threads at the next transfer, the saine weft-thread al- Ways passing over the other.
