To all whom t may concern..-

Be it known that I, BENJAMIN L. SToWE,

of Brooklyn, Kings county, New York State,

have invented a new and useful Improvement in Belting, of wihch the following is a specification. My invention relates tol fabric belting, and is directed to means for protecting the edges of such belting from Wear due to the contact therewith of the shipper-forks ordinarily employed for shifting belts from one pulley to another. l'Io this end I combine, with the body of a fabric belt, projecting fabric-edges, which receive all the friction and consequent wear that the belt would .otherwise be liable to receive from shipper-forks, and which are independent of the belt in the sense that they may be worn away and destroyed without injuring the integrity of the main body of the belt, the latter being in the meanwhile itself fully protected from injury arising from the cause above referred to.

In the accompanying drawings, Figure 1 is a face view, on greatly-enlarged scale, of a portion of a fabric belt embodying my improvement in its preferred form. This belt is a knit belt, and on each edge (one only being shown) it has a projecting edge knit simultaneously with the knitting of the belt itself. Fig. 2 is a section bf the same on line x x, Fig. 1. In the actual web or fabric the strands are of course packed closely together. They are, however, represented in the drawings enlarged and widely separated in order that the structure of the fabric may be ymore readily discerned. In the face view, Fig. l, the fabric, for convenience of illustratiomis represented as developed or spread out at the projecting edge; but in the actual fabric each projecting edge is rolled up part-ly onto itself, as seen in Fig. 2, being caused to assume this position by the draft or tension upon the weft. Figs. 3, 4, and 5 are views of modifications to be hereinafter referred to.

In the body of the knit fabric shown there are three sets of warp-threads, A,.B, and C. The two warps A and C are Worked by a set of horizontal needles, and the warps B are worked by a set of vertical needles, and the guide for these threads B has a longitudinal 5o reciprocatory motion equal to the distance from one needle to the second one from it, said guide supplying a separate warp-thread to each needle, and each warp-thread being fed alternately to one or the other of two contiguous vertical needles. j Warps A are fed to their needles 4by a similar guide-bar, but' one that has suicient motion only to feed an individual warp to one and the same needle for each stitch. Warps C, which are small bind- 6o ing-warps, are fed to the horizontal needles by a guide which feeds a warp alternately to one or the other of two contiguous needles.

D are straight longitudinal strands laid 1n the fabric during the process of knitting. E is the weft. I'

Having indicated in a general way the structure of the body of the belt, I come now to the feature in which my improvement is found. Each edge of the fabric belt (onlyl one edge 7o being shown) consists of an additional row of looped stitches, A', similar to stitches A 1n the body ofthe fabric; but, unlike the lat-ter, they are not connected directly to or interlaced with the -stitches B, but are connected to the fabric only by the weft or filling E, which passes throughv them, and by the small binder-warp C', which is knitted into each alternate looped stitch A'. These stitches A',

vforming an edge extending beyond the body 8o of the belt, 'are caused to assume the position shown in Fig. 2 by drawing in the weft E, at the points where it passes through them, sufficiently to cause them to fold over upon the adjolning row of stitches B', and to fullyproteet all 85 other p arts of the weft. I remark that on each edge the outer row of stitches, B', of the main body of the belt are so manipulated that they will,in the absence ofthe projecting edge lA', formin effect a selvage, as shown. The 9o stitches A' form a projecting edge which can be Worn away and destroyed without impairing the integrity of the body of the belt.

The weft E is comparatively safe from Wear. The small binder-warp C', which enters alter- 95 nate loops or stitches A', will be worn away with the loops into which it enters; but as the office of said warp is merely to prevent the stitches A from raveling, it will at such time have already served its purpose.

Fig. 3 illustrates the application of my improvement to a woven belt. The figure is a 5 plan view -of a part of a belt, representing one edge only. F is thebody of the belt, and G is the projecting fabric-edge, which in this instanceis a braided edge. The manner in which this combination can be made will be readily xo understood by those versed inthe art, and requires no further explanation. In this figure,

asin Figs. 1 and 2, the strands are represented as very much enlarged and spread apart, for convenience of illustration. i 5 The projecting fabric-edges just described are, it will be noted,ones which have crisscross or zigzag threads or strands to receive the wear of shipper-forks, so that no long A threads willbe released when the edges bezo come` worn. 1 I prefer to obtain this result withedges which are incorporated with the body of the belt during the process of manufacture, But the same result can measurably be attained by the employment of sepa- 25 rateprojecting strips of fabric cutbias and secured one to each edge of the belt by rivets, as in the sectionallview, Fig. 4, where a is the belt, b the bias strip, and c the rivet; or by stitching, asin the sectional view, Fig. 5, where a b d represent the belt, the bias strip, (in 3o thisrinstance folded,) and the thread, respectively. The strips may also be attached by cement or other convenient means.

The edges may be treated with rubber, oil, paint, or other substance that will increase 3 5 their resistance to friction.

What I claim herein as new and of my own invention is` The combination, with a fabric belt, of separate vprojecting fabric edges secured 4o thereto or incorporated therewith, and having criss-cross or zigzag threads to receive the wear, ysubstantially as hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 5th day of January, 1885.
