WVILLIAM STOKES AND ROBERT HUDSON, OF STOOKBROOK MILLS, ENGLAND.

ELASTIC WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 495,762, dated April 18, 1893.

Application filed August 21, 1891. Serial No. 403,326. (Specimens) Patented in England January 21, 1885, N0. 877- To aZZ whom it may concern.-

Be it known that we, WILLIAM STOKES and ROBERT HUDSON, subjects of the Queen of Great Britain, and residents of Stockbrook Mills, Derby, England, have invented certain new and useful Improvements in Elastic Woven Fabrics, (patented in England J anuary 21, 1885, N0. 877,) of which the following is a full, clear, and exact description.

This invention has for its objectimprovements in the manufacture of elastic webs suitable for insertion as gores or gussets in clothing, boots and shoes, and other articles requiring elasticity.

Our invention has for its object the production of elastic web with a perfectly smooth diagonal cloth or satin face, enabling a large quantity of material to be thrown on the face thereby making it durable and smooth. The face can be made in silk, schappe, mohair, cotton, wool, or similar fibers.

In manufacturing ourimproved elastic web we may use harness shafts, Worked by cams or tappets on a revolving barrel, or shaft, or we can use a Jacquard machine, or other suitable method of operating our shafts and shuttles, as will be understood.

In the accompanyingdrawings forming part of this specification, Figure 1, is avertical sectional elevation of so much of a loom as is necessary to illustrate the manufacture of our improved web. Fig. 2, is a. diagram, illustrating the diagonal character of the face as shown by the position of the several binders. Fig. 3, is a longitudinal section, showing the position of the various binder or warp threads in the fabric, (the stuffing warp being omitted) at each pick or chute of the weft, and the arrangement of the wefts. Fig. 4:, is a diagrammatic plan view of the threads representing the surface of the fabric.

In practicing our method of weaving the improved web by the use of tappets or cams on a revolving shaft or barrel to operate the harness, we use six harness shafts for the binder threads. The section in Fig. 1, is taken as the shuttles P P are going past the center of the front of the sley O, and passes through the center of the shuttles and binder shafts A B C D E F The view also shows the position of these various binder shafts and also that of the tappets A, B, C, D,

E, F, operating them when the tappet A is perpendicular. The position of the levers A, B, O, is also shown, but levers D, E, F, in this position are not seen, as they are neces sarily behind lever O. p

K L are the edge wire shafts. G, l'l,I, the rubber warp shafts.

J is the stuffing shaft.

M is the rubber. N the warp. O the sley. P the top shuttle, P the bottom shuttle.

Q, is the fabric issuing from the loom. R cords for the weights.

As shown, tappets are used to operate the binder shafts and are set on a spindle 40 as in Fig. 1.

The levers A, &c., for operating theharness or binder shafts A &c., are fitted with friction rollers as shown for the tappets A, &c., to ride on. When harness or binder shaft A is atthe bottom, the shuttle P goes over the warps carried by it one chute. This shaft A then rises to the center and the shuttleP goes over the warps carried by it twice. The shaft A then rises to the top and stands still while the shuttle P goes under the warps carried by it once, the shaft A then falls to the center and the shuttle Pgoes over the warps carried by it twice and afterward the shaft A falls to the bottom and the shuttle P goes over the warps carried by it once. The movement of shuttle P thus makes the face of the fabric and the corrresponding shuttle P the back. Shafts B 0 D E, F, repeat the above operation in consecutive order. By this action of the binder shafts and shuttles such satin or smooth face and back are produced, by the weft thrown up by the binders. The stuffing shaft J is placed as a fixture in the center as shown, but the stuffer warp may be omitted.

In the drawings Fig. 1, the binder shaft A is shown at the top, the shuttle P is going past the center of the sley 0. One edge-wire shaft L is then at the center and the other K down. Harnessor binder shaft B is down while shafts C D E F are at the center as is also shaft 1, and necessarily the fixed stuffing shaft J. The shafts G H are down. The next movement of the loom will at once be apparent to any practical weaver in reference to the foregoing description of the method of weaving the web with our smooth face and back.

In Fig. 2 the diagonal character of the face is shown by the position of the binders lettered A B O D F. and F G, H, and I, being the rubber shafts. In the longitudinal section Fig. 3, the binder or warp threads are indicated by the letters A B C D E F the

numbers

1, 2, 3, 4, 5, 6, denote the six picks, the position of the various warp threads at each pick being clearly shown.

We have not shown the application of J acquard or other equivalent mechanism to the tappets shown as such machinery, as that now in use can be adapted for the purposes of our invention by any intelligent weaver.

By reference to Figs. 3 and 4, and especially in the latter figure, where the small semi-circles 20 represent the points at which the warp threads pass over and outside of the back weft threads, it will be noticed that the pair of threads A B as they lie in the fabric are oppositely arranged,that is to say, the thread A passes out over the face weft while the thread B passes out over the back weft thread directly opposite, they then pass into the middle between two weft threads on the face and back respectively, and then the thread 13 passes out over a face weft while at the same point the thread A passes out over the opposite back weft after which both threads pass into the middle again and then pass as before. The next pair of threads 0 D lying respectively to the right and adjacent to the threads A B pass in the same manner but while the first pair mentioned, A 13 pass out over the first weft thread, Figs. 3 and 4, on the face and back respectively, the second pair 0 D pass out over the next weft threads on the face and back, numbered 2. The third pair of warp threads, E F pass in the same manner, but are bound by the third Weft threads.

Having thus described our invention, what we claim is A fabric consisting of central rubbers, a series of face wefts, and a series of back wefts, a series of six warp threads arranged in pairsA B 0 D and E F, the thread A of the first pair passing out over the face weft 1 and the thread 13 passing out over the opposite back weft 1 both threads then passing in the middle between two

face weft threads

2 and 3 and two back wefts 2 and '3, the thread A then passing out over a back weft 4: while the companion thread 13 passes out over a face weft 4; the second pair of warp threads 0 D passing in the same manner with relation to the next weft threads 2, and the third pair of warp threads E F also passing in a similar manner with relation to the third weft threads 3, each weft thread being floated over the rubbers and all the threads of the several pairs excepting the one'which binds it, substantially as described. In witness whereof we have hereunto set our hands in presence of two witnesses.
