E SCHMIDT Machine Belting.
No. 229,190. Patented June 22,1880.
EDMUND SCHMIDT, OF CHEMNITZ, SAXONY, GERMANY; J OHANNES HEINRICH REITZ, ADMINISTRATOR OF THE ESTATE OF SAID EDMUND SCHMIDT DECEASED.
MACHlNE-BELTING.
SPECIFICATION forming part of Letters Patent No. 229,190, dated June 22, 1880. Application filed May 6, 1879. Patented in Germany May 24, 1878.
To all whom at may concern:
Be it known that I, EDMUND SCHMIDT, of the vcity of Chemnitz, Kingdom of Saxony, Germany, hav invented a Cotton Machine- Belting, of which the following is a specification.
My improvement relates to woven belting adapted for use in driving machinery by pulleys or belt-wheels; and the object of my im- 10 provement is to prevent the belt from twisting when in use, to cause it to have a smooth and close hold upon the pulleys or wheels, and to prevent all tendency to side draft or slipping from the pulleys when working. In the i5 accomplishment of these objects I form a new article of maehine-beltin g.
I have shown in the accompanying drawing a representation of a piece of belting formed according to my improvement.
By my improvement cotton belting is made so that one half of the warp is composed of right-twisted cords and the other half of the warp of said belt is composed of left-twisted cords, making in effect belting divided into 3 two longitudinal halves, A B, the longitudinal center C being the dividing-line, so that one half acts to counteract the other half of any tendency or action to twist, or work from a true draft or pull upon the pulleys. The mere use of right and left twisted warp cords is not sufficient to produce this result in machinebelting irrespective of the equal division of the width of the belting in right and left twisted cords woven together. By this means a true- Working belt, when in motion, is produced. A
more desirable and easier-working belt is produced.
In weaving this new cotton machine-belting well-twisted cords, made from the best quality of cotton, are to be used. These cords vary in size according to the strength and thickness of the belting required. Each cord is composed of a number of smaller well-twisted strands or threads braided or twisted together. The cords are spun and produced in -the usual 5 manner.
I am aware that prior to my invention textile wearing fabrics have been woven in which the warp or weft, or both, have been twisted in contrary directions, for the purpose of produc- 5o ing craped or erimped surfaces when subjected to the action of water, causing the same to curl, shrink, or contract, and to assume an uneven surface having a loose or floating back and a orape face. I therefore do not claim, 5 broadly, the twisting of the warp or the weft, or both, of woven fabrics in contrary directions for wearing-apparel, nor would such production be suitable for machine-belting, which must have the distinctive feature of an equal division of the contrary or right and left twisted cords to produce the results described-that is, to prevent the belt from twisting when in use, and to effect other advantages which are important and only desirable in machine-belt in The belts are generally oiled, varnished, or painted.
lVlachine-belting having the warp composed of right and left twisted cords, the belting being equally divided longitudinally by such contrary-twisted cords, whereby one half of the belting, when in use, acts to counteract the tendency to twist of the other half, and thus give a true draft or tension upon the pulleys, substantially as herein set forth.
Chemnitz, SaXony,.July 18, 1878. EDMUND SCHMIDT.
