  • Driven roller tube conveyor
    Patent number: 4507137
    Abstract: A conveyor apparatus for receiving and transporting cylindrical stock or articles past work stations includes a plurality of rollers disposed along spaced-apart parallel axes. The rollers are driven through one-way or overrunning clutches and rotate cylindrical stock disposed between adjacent pairs of rollers. At a work station, a moving member such as a belt engages the stock and rotates it at a speed higher than the speed imparted to it by the rollers. The overrunning clutches release the conveyor rollers and rotate with the stock at a correspondingly higher speed. The constant, non-slipping contact between the rollers and stock minimizes such difficulties as scoring of the stock and significantly improves product quality and appearance.
    Type: Grant
    Filed: November 30, 1983
    Date of Patent: March 26, 1985
    Assignee: Owens-Illinois, Inc.
    Inventors: Ralston G. Edwards, Jr., John R. B. Walkden, Walter H. Carstensen, Gregory E. Murphy, John E. Lisi
