TO ALL WHOM IT MAY CONCERN:

Be it known that I, M. JOHN I-IAINES, of Bristol, England, have invented an Improvement in the Manufacture of Driving-Straps or Belts and I do hereby declare the following to be a full, clear, and exact descripd tion of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon. I

This invention relates to a peculiar manufacture or construction of straps or belts intended to be employed in driving machinery of all kinds, and consists essentiallyy in constructing such straps of a number of longitudinal strips of leather, hide, or other suitable materia-l, of a width equal to the thickness ofthe intended strap. These strips are placed side by side, with the cut edges of the leather or other material coming to the upper and under surfaces of the intended driving-straps until the desired width is obtained. I do not confine or restrict myself to any particular mode of fastening or securing these longitudinal strips together, but the special means hereinafter describe..l and `illustrated by my drawings and specimens will be found te answer well in'practiee.

In arranging the strips side by side care should be taken that the ends of the several strips shall break joint with each other, or, in other words, that no tW'o joints shall be in the same transverse line, by which arrangeinenta uniform strength of strap throughout its entire length will be obtained. And in order that my said invention may be fully understood, I' shall now proceed more particularly to describe the same,I and for that purpose Ishall refer to the several Vfigures in the accompanying drawing, which forms apart of this specification, and in which-L- I Figure l represents a plan and partial horizontal section of a driving-strap constructed according to my invention; and

Figure 2 isa transverse section of the same.

a a represent the strips of leather, hide, or other material, which are cut to a width equal to the thickness of the intended strap, as shown clearly in g. 2, and a number of these are placed side by side suiieient to give the desired width of thevstrap. In figs. l and 2 the strips are represented as being fastenedtogether by introducing transversely lengths of iron, copper, or other wire, 6, through holes made in the several strips a, each rod or length of wire b having a head formed at one end, whilst its opposite end is turned overclinched er riveted on to a washer after it has been inserted; or the several strips may be united together byy screws, I), as shown in Figures 3 and 4, screwing through and into the holes in the several strips c, the screws being screwed into the holes alternately, rst from one edge ot' the strap, and then from the other, so that the heads of halt the screws will been one edge, and the heads of the other half will be on the opposite edge of the strap, as shown clearly in iig. 3; or the several strips a maybe connected or fastened together, after having had holes made through them, by means of copper or other wire, b, as show'n in Figure 5, two wires being employed for this purpose, and both wires being passed in opposite directions through cach hole from side to side of the strap. Each wire after it has passed through one hole is bent round and passes throughthe next hole, and so on; or in place of wire being employed, the several strips may be sewn or laced together, as above described, by means of twine, leather thongs, or other material. The several holes for receiving the faistenings may either be made after the strips have been placed in position, or the strips may be separately perforated and then placed side by side so that the holes may correspond.

Figures G and 7 represent a mode of fastening or securing together the strips c by means of long lengths or strips of leather, I), which are passed te and fro through holes in the strips a from one side of the strap to the other, and back again, outside strips, c c, being nailed, screwed, or otherwise secured over two edges ofthe strap so as to protect the fastening strip Z1 at those parts Where it is left exposed by passing from one hole to another.

` Figure 8 represents a plan and partial horizontal section ot' another mode or method of securing together the longitudinal strips composing the drivingstraps.

Figure 9 is a transverse section, taken along the line l-2 in iig. 8; and

Figure 10 is a section, taken along the line 3-41.

a a are the longitudinal strips, and b the fasteners, which, in this case, consist of short lengths of leather,

emesA 2 passed transversely through holes or slits in the strips a, and having their opposite ends secured between two or more layers of flat strips, d, of leather, or other suitable material, by means of rivets ce, which pass through the strips d and through the fasteners b, and secure the whole {irrnly together. It desired, theI fasteners b may be composed of thin strips of metal in lieu of leather; and it is preferred to secure theV edges of the strap by oneor more lines of stitches', as shown at ff.

Figure 11 is a plan and partial horizontal section of a driving-strap, wherein the component strips a are secured and held together by a series of detached lengths or strips of leather, I), passing transversely through the several strips a, and being secured to the outer strips by having their protruding ends turned over and nailed or screwed down, as at g g, outside strips e c being nailed, screwed, or Aotherwise secured to the edges to give a finish to the strap.

Having now described and particularly ascertained the nature of my invention, and the mans for carrying out the same in practice, I would observe in conclusion that what I claim as novel and original, and as consti-' tilting the essential feature of my said invention, is-

1. The construction and use of' driving-straps or bands composed of a number ot' vlongitmlnal strips of leather, hide, or other suitable material ofa width equal to the thickness ofthe intended strap, and placed side by side, and secured together in any convenient manner.

2. The peculiar modes ot' fastening or securing together a number of longitudinal strips of leather with a view to forming an edge-laid driving-strap or band, substantially as hereinbefore described, and illustrated byv my drawings. I A

In testimony whereofI have signed my name tothis specification in the presence of two subscribing witnesses.
