VILLIAM LAPWORTH, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TC THE HCPEDALE ELASTIC FABRIC COMPANY, OF SAME PLACE.
CORDED OR ELASTIC FABRIC.
SPECIFICATION forming part of Letters Patent No. 402,844, dated May '7, 1889.
Application filed December 8, 1888. Serial No. 293,002. (Specimens.) y
To all whom it may concern:
Be it known that I, WILLIAM LAPWORTH, of Hopedale, county of Vorcester, State of Massachusetts, have invented an Improvement in Corded or Elastic Fabrics, of which the following description, in connection with Jthe accompanying drawings, is a specification, like letters on the drawings representing like part-s.
This invention has for its object the production of a novel corded fabric, it having preferably some elastic warps in order to make the fabric elastic.A
My improved fabric is so constructed, as will be described, that it presents longitudinal ribs or portions wherein the fabric is woven double and contains between its upper and lower plies a filling-warp, which may be of any usual material, but preferably of indiarubber, the portions of the fabric between the said ribs being of single ply, containin a cord or rubber warp, which -latter is covered at bottom and top by only the filling. Herein each ply of the double portion of the fabric is represented as woven to present the appearance.
to the eye of a plain fabric; but I do not desire to limit my invention to making the said two plies of the particular style referred to, but may make each ply above and below the cord or rubber warp of the rib of any common or usual form of bind. Preferably the warps entering into the two plies of the double part of the fabric to form the longitudinal ribs will be of different colors, so that the ribs at opposite sides of the fabric will present each a` different color from the other, thus making it possible to cause the two faces of the fabric to present an entirely different and distinct appearance, and cit-her face may be shown, as desired.
My invention consists, essentially, in a fabric composed of double and single fabric eX- tended parallel to the .length of the fabric, the double portion of the fabric containing between its plies a cord or rubber warp to aid in constituting a rib, the single portion of the fabric between adjacent double portions containing also a cord or rubber warp, which is covered only by the weft or filling.
Figure l is an enlarged detail of a portion of the fabric, the said figure showing the threads which enter into the formation of the double or ribbed part of the fabric, with threads at one side thereof to constitute the single part of the fabric. Figs. 2 to 5 show enlarged sections of the fabric for four consecutive picks. Fig. 6 shows the repeat of the pattern. Fig. 7 shows a longitudinal section with the threads opened up, and Fig. 8 is a cross-section of the fabric shown in Fig. l to include the iirst and second picks.
' The fabric herein shown is woven with what is called a four-time motion-that is, the fabric is repeated longitudinally with ihecommencement of each iifth pick.
Referring to the drawings, r shows the cord or rubber warp for the double or ribbed part of the fabric, the fibrous warpsy entering into the said double portion to constitute the enlarged longitudinal ribs of the fabric being marked c d, c d', and e f c f those marked c d c d constituting the group of warps for one ply of the doubled part and appearing only at-one side or face of the fabric, while the threads marked e f e f constitute the fibrous warps for the other side or face of the fabric, and they also appear at but one side or face. These groups of warp-threads are preferably of different colors, so as to produce ribs of different colors at the opposite faces of the fabric; but they may be of one and the same color, or of the same color differing in shade.
The group of threads c cl c el will be carried by two harness-frames, those marked c c being in one harness-frame and those marked Cl d in another harness-frame, while the group of threads e f c f are carried by two other harness-frames, those marked e c in one frame and those marked f f in another harness-frame, the cord or rubber warp r', as well as all the cord or rubber warps r r2, used in the single portions of the fabric to be described being commonly in one harness-frame, as such cord or rubber Warps may be always moved up and down together.
The fabric herein shown has a Weft or filling thread, w, carried by a single shuttle.
I have shown and described four threads as employed in each group of threads to con- IOO stitute the two plies of the double part of the fabric; but I do not desire to limit my invention to the exact number of threads in each group, no1' to the exact number of threads in each of the said groups, which shall be carried by either of the harness-frames controlling the threads of a group, nor to the exact number of harness-frames to receive the threads of each group.
In the drawings I have shown eight warpthreads besides the rubber or cord warpthreads for both the doubled and the single parts of the fabric, and the threads for the body of the fabric for its entire width are but a repetition of the threads shown in Fig. 1.
The threads for the single part of the fabric, besides the rubber or cord warps r r2, are marked a h a b', there being, as herein shown, eight such threads in each longitudinal portion of single fabric, the said portions of double and single fabric extending side by side throughout the length of the fabric.
The fibrous threads a l) a b are carried into two harness-frames, those marked a ct in one frame and those marked b Z7 in another frame, the said threads being separated by the harness-frames, carrying them in such time and order as to weave with the weft-thread a fabric of single thickness and leave the cord or rubber warps r r2 covered at bottom and top by only the said weft employed to unite the threads constituting both the double and the single portions of the fabric, as will be described.
The weftthread referred to,where it crosses the cord or rubber Warp rr?, presents smooth surface composed entirely of weft laid against weft, which contrasts strongly with the ribs of the double fabric, which, it will be understood, present at opposite sides of the fabric a distinct fabric composed of both warp and weft lying above and below the cord or rubber warp r.
The warp-threads ce b a b constitute binder-warps for the fabric at opposite sides the double or ribbed portions.
I do not desire to limit myinvcntion to the exact number of warp-threads, as a b a D, used in the plain or single part of the fabric with the cord or rubber warps fr r2, nor do I desire to limit my invention to the exact number of cord or rubber warp-threads employed in the single-thickness part of the fabric with the warp-threads a b a b', and to be covered only by the weft, for I may use one or more side in the dents of the usual reed and in the harness of the harness-frames according to the width of the fabric.
Referring to Fig. 2, showing the warp separated for the first pick, it will be seen in that part of the fabric which is to be woven double that the warp-threads marked c c of the group of threads c d c d are down,while the cord or rubber r and the threads CZ d c f e f are up, and then, in Fig. 3, showing the second pick, the threads e and e of the group, e f e f are left up, and the cord or rubber r and all the threads c CZ c d of the other group, as well as the threads ff', are down. In the third pick the threads d and d of the group c CZ c cl are down, and all the threads e f ef and the rubber r up, while in the fourth pick the threads c e d, the rubber r', and the threads c c' CZ go down, leaving the threads f and f up. The fifth pick is the same as the `Iirst.
By shedding the warps and introducing the weft in the manner described it will be apparent that two plies of fabric will be formed one above and the other below the cord or rubber warp r, and these plies at their edges will be brought together and united by the warp-threads marked a b a b and the weft uniting them.
Referring again to the first pick shown in Fig. 2, it will be noticed that the warps l) b are down and the warps a a are up with the cord or rubber warps r rfor the second pick only the cord or rubber warps r r2 are changed, they being lowered, while for the third pick the warps I) D and the rubber rise and the warps d ce go down, the said warps b b' and a a remaining in the same position for the fourth pick as the cord or rubber warps o" r2 go down for the fourth pick. The fifth pick is a repetition of the iirst.
I claim-` A fabric composed of double and of single fabric extended parallel to the length thereof, the double portions of the fabric containing between its two woven plies a cord orrubber warp to aid in constituting a rib, the longi* tudinal single portion of the fabric between adjacent double portions containing also a cord or rubber warp, as described, which is covered at bottom and top by only the weft employed to unite the threads constituting both the double and the single portions of the fabric, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
IVILLIAM LAPVORTII.
