Abstract
983,441. Roads. W. E. & F. DOBSON Ltd. May 19, 1961 [May 25, 1960], No. 18384/60. Heading E1G. [Also in Division F1] A kerb is movable from an inoperative to an operative position or between two operative positions to divide streams of traffic in a roadway. As shown, kerb sections 2, 3 are supported on cross members 4, Fig. 2, in a pit 5 and raised and lowered by hydraulic rams 7, the rams associated with one kerb section being linked to each by piping 8 and to the rams of adjacent sections and to control means 9 by piping 8b and 8a respectively. In an alternative embodiment (not shown), a kerb permanently projecting above the roadway surface is movable transversely of the roadway by horizontally-displaceable hydraulic cylinders mounted in the roadway and pivotally connected to the kerb or by hydraulic motors built into the kerb.
