Abstract

1,052,264. Belt gearing. STEPHENS BELTING CO. Ltd. Dec. 4, 1963 [Sept. 4, 1962],No. 33785/62. Heading F2Q. In a driving belt having reinforcing cords running longitudinally in one or more layers adjacent the outer surface of the belt, the tensions in the cords are initially adjusted so that in one or more circumferential regions spaced inwardly from the belt edges the tension in the cords is less than that in the cords over the remaining regions. The belt 17 shown has cords 19 adjacent its edges at one tension, while over a central region 22 the tensions in cords 20 decrease progressively from the sides of the region to a minimum at the central plane, giving good engagement with a pulley 10 having a peripheral rib 13, as described in Specification 968,645, to prevent running off. Alternatively, the cord tensions may decrease progressively from the edges of the belt to a minimum at the central plane, for engagement with a pulley having a transversely convex rim. The belt may be of leather with reinforcing cords of nylon or other suitable plastics material.
