BELTING.

SPECIFICATION forming part of Letters Patent No. 577,376, dated February 16, 1897.

Original application filed May 25, 1895, Serial No. 550,6 '74. Divided and this application led April 25, 1896. Serial No. 589,105. (No model.)

T0 all whom t may concern.:

Beit known that I, J AMES FREEMAN BRO WN, of Needham, in the county of Norfolk, State of Massachusetts, have invented certain Improvements in Belting, of which the following is a specification.

This invention relates to improvements in a belting for which I have applied for Letters Patent of the United States, iiled May 25, 1895, Serial No. 550,674; and the object of these improvements is to both cheapen the expense of making this particular belting j ust pointed out and to lighten its weight.

The accompanying drawings, together with the following description, illustrate the nature of my invention.

Figure l isa plan view of my invention. Fig. 2 is an edge view of Fig. l. Fig. 3 is a plan View of the textile fabric or material, illustrating the nature of my invention. Fig. 4 is a modification of Fig. 8.

A represents my belting, the nature of which will appear in detail in the following subjectmatter. Y

B denotes one of the textile fabrics, and C is the other textile fabric or material. The former is in nature as follows: b represents warp-threads or longitudinal cords, and b Woof-threads or transverse cords. In this material or fabric the association of these Woof-threads with the warp-threads is simply for the purpose of keeping the warp-threads or longitudinal cords in their relative position, and the use of these Woof-threads is as limited as possible, so as to attain as much as possible a straightness of the longitudinal cords without curves or crimps caused by the association of the transverse cords with the longitudinal cords in the ordinary manner of weaving. The latter fabric is in nature as follows: c represents Woof-threads or transverse cords, and c' warp-threads or longitudinal cords. In this material or fabric the association of these warp-threads or longitudinal cords with the Woof-threads or transverse cords is simply for the purpose of keeping the Woof-threads or transverse cords in their relative position, for should there be a number of these warpthreads greater than the number used for the purpose mentioned they would have no function to perform, as clearly specified in my previous application, to which reference is made. This material C is employed solely for the purpose of preventing a longitudinal tear or ripping of the belting, caused by connecting the two ends of the belt together, either by lacing or by any other means, and by an excessive strain upon the beltin g or belt designed and made without this material O. Fig. 3 illustrates this textile fabric or material C as having Woof-threads for a certain distance of its respective ends and a space between the respect-ive inner ends of the Woof-thread portions without Woof-threads, but simply the Warp-threads that keep the woef-threads in their relative position. A belt having this material is designed for a certain purpose or special use and is not intended to be used for the same purpose requiring a shorter belt, for by so doing it would necessarily require the belt or belting to be cut, so as to shorten its length, consequently causing it to lose the element contained in this material C, provided that when cut this material C had no relation or was not associated with the other material in the part used.

Fig. 4 illustrates that in order to attain that which has just been described it is not necessary that the material C should be in length equal to the other material B, but that pieces of the material C may be placed on the material B at its ends without having warp-threads running the entire length and in connection with the Woof-threads, as shown by Fig. 3, for by placing together and treating with rubber or any other suitable substance, compound, or material (represented by D) these two materials or fabrics B and C, or by folding and stitching them together, I eifect an entirety or whole. Any strength can be attained by longitudinally folding these materials.

Having described the nature of my invention, I claiml. A belt or belting made of two materials, or textile fabrics, one consisting of warpthreads or longitudinal cords, having associated therewith, Woof-threads or transverse cords as few as possible simply for the purpose of keeping the warp-threads or longitudinal cords in their relative position, and the other material or textile fabric consisting of Woof-thread portions for a suoient distance of its respective ends, and a blank Woof-thread space between such Woof-thread portions, and having associated With the Woof-threads or transverse cords warp-threads or longitudinal cords, as few as possible simply for the purpose of keeping the Woof-threads or transverse cords in their relative position; associated together and treated With rubber or any other suitable substance, compound, or material, and folded and stitched together, as and for the purpose described.

2. In a belt or beltin g, two materials or textile fabrics, one consisting of Warp-threads or longitudinal cords having associated therewith Woof-threads or transverse cords, as few as possible simply for the purpose of keeping the Warp-threads or longitudinal cords in their relative position, in combination with the other material or textile fabric consisting of Woof-threads or transverse cords having associated therewith Warp-threads or longitudinal cords as few as possible simply for the purpose of keeping the Woof-threads in their relative position, being for a suiiicient length applied to the respective ends of the first-mentioned material, as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribin g witnesses.

JAMES FREEMAN BROWN.
