ELASTIC WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 314,581, dated March 31, 1885.

Application filed November 10, 1883. (No model.)

To @ZZ whom, it may concern:

l Be it known that I, WILLIAM E. JEFFER- SON, a British subject, residing at Nottingham,

in the county ot' Nottingham, England, have invented a new and useful Improvement in Elastic IVOVen Fabrics, of which the following is a specification, reference being had to the accompanying drawings.

In the manufacture of boots and shoes composed in part of the elastic woven fabric now in use, there areaptto belumps, abruptridges, and excessive and clumsy thickness of mate rial Where the woven fabric and leather are united. In boots and shoes made Wholly of leather thedilticulty is overcome by skiving, but such method cannot be pursued when elastic woven fabric is used; and the`object of my invention is to overcome the difficulty in Loots and shoes composed partly of elastic woven material. To this end the invention consists in an elastic woven fabric having a margin of gradually-diminishing thickness toward and to the selvage.

The structure or texture of the fabric may be varied; butin carrying out my invention the fabric which is the subject ot' my United States Letters Patent No. 216,328, dated June l0, 1879. may be very advantageously adopt` ed, and I have selected that fabric for the illustration of my invention.

Figure l is a longitudinal section of the body of the fabric. Figs. 2, 3, anda are longitudinal sections ot' the fabric, which are taken successively on lines nearer to the sel vage. y

Fig. l shows the body fabric to contain four Wraps-viz., the elastic Warp,theindiarub berthrcads of which are represented by the heavier unbroken lines A, the face-Warp, the threads of which are represented by the heavier dotted lines B, the back Warp, the threads of which are represented by the lighter dotted lines C, and the binder-Warp, the threads of which are represented by the lighter unbroken 45 lines. Fig. 2 shows the commencement of the reduction of thickness by the omission of the back warp only. Fig. 3 shows a further reduction, nearerthe edge, by leavingout not only the back warp but the elastic warp. Fig. 4 shows a still further reduction, nearer the edge, and 5C which is intended to be continued to the se1 vage, by leaving out the elastic Warp and alternate threads of the face-warp, leaving the fabric near and close tothe selvage composed only ofthe weft, the bindei-warps,and a small 55 portion of the face-warp.

By thus omitting certain of the warp-threads, commencing at a point, say, half an inch from the selvage, and omitting more and more toward the selvage. a gradual reduction of the 6o thickness of the fabric is effected,and a tapering of the margin subslantiallylike thateffecteil in leather by ski ving is produced. The gradual reduction or tapering of the margin ot the fabric in this manner provides for the production of athick, soft, and cushioulike fabric, which is very suitable for those portions of boots and shoes which are required to be elastic and sott, and which can, notwithstanding its great thickness, be so joined to the leather 7c and lining as to enable a very neat finish to be made where the rubber, the leather, and the lining come together.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. An elastic woven fabric havingamargin of gradually-diminishing thickness toward and to the selvage. substantially as described.

2. The elastic fabric herein described, containing in its body' elastic warps and binder- 8o warps, a facewarp With terry-loops, and a back Warp with terry-loops and having its margin gradually reduced in thickness by the omission of the back warp, the elastic warp, and portions of the tacewarp, substanv tially as herein described.
