Abstract

333,078. Ternon, T., and Gallien, E. Oct. 5, 1928, [Convention date]. Road signals.-Signals F at cross-roads are actuated through pneumatic or hydraulic transmission by approaching vehicles depressing pivoted road members A. Each member A when depressed actuates, through a spindle B and lever C, a pump D supplying pressure fluid through a pipe K to the piston operating a signal arm F. A helical pump P driven by the depression of the member A removes dirt &c. from below the member A to the road surface by way of a duct O.
