To all whom it) may concern:

Be it known that-I, GEoReE WILLIAM PARKEs, a subject of the King of Great Brit ain and Ireland, and .a resident of Manchester, in the county of Lancaster, England,

have invented new and useful Improvements in and Relatin to Drivingelts or the Like, of which the fo lowing is a specification.

This invention relates to woven or similar driving belts or bands and thelike or to a belt or. the like formed or provided. with-a surface composed of a woven fabricand its the pulley.

' In carrying these improvements into effect object is to so construct them that the faces, edges, or other parts exposed to wear on an one or more of such arts may be prote'cte and incidentally to 0% common in the manufacture of iled fabrics. This piled'or looped part of a. elt may be woven with or be lntegralwith the body of the belt, or it may consist of a separately-formed piece of fabric whioh'covers or partially covers the belt. In a belt composed of canvas or other fabric folded upon itself several times that part of the fa ric which will be outside when the belt is made may be woven with the loops. or pile, the remainder of the fabric being woven in the usual manner.

An convenient number of threads may be uti 'zed for forming the loops or ile. The loops or the pile maybe 'roduced in any of the well-known ways an either in the warp or 1iTn the weft.

re 1 shows in cross-section a belt com- 1 pose of several plies or layers ab 0, the outer duced in it. As before exp one of which, 0, has loops-formed u on its surfaceand is disposed upon'theot ers 'in' such a manner that its looped face is the one which comes against the-pulley or the like. The loops are indicated at d. The looped surface may merely extend across the face of thebelt or it may extend to some extent around the edges, as shown in the drawings. Fig. 2 is-a simi eral times, that part which is to form a face of the complete elt having the'loops d proained, the looped Speeification'of Letters Patent.

Fig. 4 shows a belt provided with a. looped driving-face disposed around two pul-' leys e and f and illustrates the contact of the loo ed or iled surface (1 with the faces of the pul ey. I v ig'.'5 shows in section a solid woven driving-belt having loops d produced'upon'one of its faces.

.. Itwillbeunderstood, of course, thatinstead of the belt being whollycomposedof textile or woven material it may be partially composed of leather or other suitable substance covered on one face at least with a fabric hav-:

I V A belt formed as described may have any In the example illustrated the belt is only known and suitable protective edge com fit beg, so formled' obtains a perfect gripon t e pu ey or pul eysand does not slip, so that the life of a belt and its elliciency are greatly increased. Furthermore, an additionaladva-nta e is obtained by the. fact that the loops or thepile-act as a pad or elastic cushion-between the belt and the pulley, and thus relieve them both from jars and certain strains. For better cushioning and with a built up textile belt one or more of the internal parts ma also be piled or in loops.

The loops may be eft as loops, as indicated in known nianner to form va pile.

In a modified form of elt instead of pro ducing loops which may afterward be cut to thedrawings, or they may be out in the well-.

form a pile, the pile may be roduced by 1 cards or e uivalent devices in anap-raising or like inab hine.

I claim as my invention- A driving band or belt comprising a body portion of solidly-Woven fabric, said fabric having loose, comparatively flat textile loops projecting from its pulley-engaging surface,

10 and engaging the pulley whereby said loops are flattened down in use so as to form a flat I raising the textile surface of the belt by even pulley-engaging surface upon the belt.

In testimony whereof I.have signed my nanie to this specification in the presence of two subscribing witnesses.
