IMPROVEMENT IN THE MANUFACTURE OI' MAGH'INE-BELTING.

The Schedule referred to in these Lettere Patent and making part pf the sama.

To all v'whom 'it may concern :V

Be it known that we, GEORGE BURN and DANIEL BURN, of London, England, have invented a new and improved Manufacture of Leather; and We do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relatesjo an improvement in the manufacture of driving-belts for machinery; and

It consists in the formation of the same from a weft and Warp of leather, woven with selvages, Without joints or splices, and with a double face or running surface.

In carrying out our invention, we employ continuous lengths of leather, cut into a continuons length or coil, by causing a knife, or suitable cutting-instrument, to pass over its entire surface, commencing, in practice, this cutting-operation, from the' exterior of the said leather, hide, or skin, and passing the cntting-instru ment along its edge, thus dividing a string or filament of the hide or skin, of one continuons length or coil, till the whole of the leather or hide is so4 divided.

This length of leather is then further prepared by longitudinal stretching, dampening, greasing, rolling, hammering, or such other equivalent operations as may be found necessary to remove the angles or curves formed in cutting the same continuously, and in one piece, from the hide.

In producing these continuous lengths of leather, we cause a knife, properly gauged, to traversethe exte? rior edge or perimeter of the hide spirally to the centre, thus cutting the entire hide into one continuous string or band, suitable for use, as above specified.

Byl this method of cutting, we are enabled to obtain, from a single skin or hide, a thread of leather two thousand (2,000) feet or more` in length, in one piece.

The pieces, so out, are woven upon any suitable loom, with a warp of leather or vegetable fibre, into a vvariety of fabrics, such as driving-belts, harness-strips,

window-shades, Sac.

Where a driving-belt is woven, it will.. be noticed that, from the extreme length oi' the leather strips, the belt can be made suiiiciently long, without joints or splices, to accommodate any machinery, and also that both sides constitute running surfaces.4

By referring to the accompanying drawings, the manner of cutting the continuous strip will be seen at Figure 1., A beingtho uncut port-ion of the leather, and B, the strip,.as partially cut. ,'lhc dotted lines show the spiral path of the knife.

Figure 2 is a section of iig. l, through the lille a ax.

Figure 3 shows a hide from which wider strips are cut than'in iig. 1.

Figures 4 and 5' represent the leather strips, arranged in hanks or skeins for use, iig. 5beingr a transf verse section of fig. 4.

Figure 6 represents leather webbing, formed by weaving with a warp and filling of leather-.or vegetable fibre.

Figure 7 representsa coarser specimen of' weaving,

for driving-belts and other-fabrics. If found desirable, the hair may be left upon the hide.

Having thus described our invention,

What we claim as new, and desire tol secure by Letters Patent, is,

As a new article of manufacture, a. driving-belt for machinery, formed from a weft and warp of leather, woven with selvages, without joint-s or splices, and with a'double face or running surface, 'as herein shown and described.

The above specilcation of i our invention signed by us this 29th day of July, 1867.
