Title (EN) RAIL SUPPORT WITH PROVISION FOR BALLAST
(FR) SUPPORT DE RAIL AVEC RESERVOIR DE BALLAST
Abstract: front page image
(EN)A novel railroad crosstie (1) is disclosed comprising a cavity-reservoir (4) which serves as a container for small grade ballast or pea gravel which is automatically directed underneath the crosstie (1) in proportion to the settlement of the underlying ballast. New small grade ballast or pea gravel is automatically deposited as a result of the combined effects of gravity and the amplitude of vertical oscillation introduced by the wheel sets of passing trains.
(FR)Une nouvelle traverse de chemin de fer (1) comprend une cavite (4) formant reservoir contenant du ballast de granulometrie fine ou du gravier fin, qui est automatiquement depose sous la traverse (1) en fonction du tassement du ballast sous-jacent. Le complement de ballast de granulometrie fine ou de gravier se depose automatiquement sous l"effet combine de la gravite et de l"oscillation d"amplitude verticale produite par les roues des trains qui passent.
