  • Transferable roadway lane divider
    Patent number: 4500225
    Abstract: A roadway lane divider comprises a plurality of interconnected divider sections each having a T-shaped upper end. Rollers of a mobile transfer apparatus are adapted for engagement under a pair of longitudinally extending undercut bearing surfaces, defined on the upper end of each divider section, to lift and suspend the divider sections as a unit on a first side of the apparatus, move them serpentine-like across the apparatus and deposit the divider sections on a second, opposite side of the apparatus.

  • Moveable lane barrier locking system
    Patent number: 4498803
    Abstract: A plurality of closely spaced and pivotally interconnected divider sections form a roadway lane divider and barrier. The divider sections are adapted to be lifted and transferred on a roadway as a unit. A plurality of releasable locking members are reciprocally mounted on respective pairs of the divider sections to either lock them together against relative pivotal movement or to selectively release the locking members to permit the divider sections to freely pivot relative to each other when they are lifted for transfer purposes.
