BELTING.

SPECIFICATION forming part of Letters Patent N 0. 650,977, dated June 5, 1900.

Application filed January 24, 1899. $erial No. 703,284. (No model.)

To all whom it may concern:

Be it known that I, GAYLARD MACK, Weaving manager, a subject of the Queen of Great Britain and Ireland, residing at 41 Rookley street, Broughton road, Pendleton, in the county of Lancaster, England, have invented certain new and useful Improvements in and in the Manufacture of Woven Driving-Belting, (for which I have made application for patents in Great Britain, No. 6,475, dated March 17, 1898, and No. 16,509, dated July 29, 1898,) of which the following is a specification.

My said invention relates to improvements in and in the manufacture of woven drivingbelting. Such driving-belting is woven in varying widths to suit requirements and is cut into desired lengths and the ends connected by fasteners. It is found in practice that various objections are inherent to this method. For instance, to cope with the demand for belting of the many difierent Widths large stocks of such varying widths of belting must be kept in hand. Further, the strength of the belting is weakened at the point of connection, and this weakness is difficult to overcome Without destroying the flexibility of the belt. These objections are fully met and overcome by my invention, which is illustrated in the accompanying drawings.

Figure 1 is a plan view of a part of a belt embodying my invention. Fig. 2 is a crosssection of Fig. 1. Figs. 3 and 4 represent a modified form of my invention. Fig. 5 shows the method of connecting the ends of a belt composed of strips.

The edges of the strips a are woven in such a manner that they may be readily sewed together with or without the stitches going through the body of the belt. To effect this, I weave the strips a so that any number of warp or weft threads, ,or both, are woven together at each edge, (or one edge only, as required,) so as to form a loop-weave b, as shown clearly in Fig. 1. The loops 1) are then threaded, as shown, and may be drawn more or less tightly together, as shown in Fig. 2.

Instead of a loop-weave the edges may be woven more loosely than the body of the belt by any suitable weave, and the edges are then sewed together. To effect this, I place the strips to be connected one upon the other, as

shown in Fig. 3, and secure the edges together by hand-sewing or by a suitable machine, the stitches being passed through the edges of the strips a or through the body thereof. Thus not only is it possible to readily construct belts of varying widths to order from such strips, but the connection of such a belt can be' easily effected to break joint. For instance, suppose a belt of thirty feet in length be built up from three strips. The ends of the strips where connected may be separated from each other a distance of ten feet apart. This is indicated in diagrammatic form in Fig. 5. The strength of the belt is increased by thus breaking up the points of connection, and the flexibility of the belt is not so much impaired as in'the case with methods at present in use. Moreover, where metal fasteners are used the weight of the fasteners is distributed over the length of the belt, and any slipping of the belt on the pulley, due to the pressure of a number of fasteners at one point, is also avoided.

The formshown in Fig. 4 and that shown in Fig. 5 are similar in that the loops of Fig.

5 are in effect tongues of reduced thickness to form the means of attachment.

The threads or stitches securing the two parts together are depressed in respect to the surface of the belt, and thus are not subjected to frictional wear from the belt-wheel.

I declare that what I claim is- A belt composed of a plurality of strips of woven material having their longitudinal selvage edges united by stitches, said stitches engaging parts of the weave of said selvage edges and being depressed in relation to the working surfaces of the strips, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GAYLARD MAcK.
