Abstract
An sir blowing system for use in deeping railroad track switches clear of snow utilizes flexible tubes, preferebly of rubber or plastic, located transversely beneath the main tracks, and connecting with resilient nozzles to direct a high flow of air in the direction of the track switch points. The system may include resilient ducts conveying air in protective relation with the switch control rods, extending laterally beneath the track. The rod protective air discharge may be by way of a louvered cross-tube, extending parallel with the rods, to discharge air laterally of the rods, or one or more nozzles discharging air longitudinally of hte rods.
Claims17
A pollutant dispersion system for dispersing air-born pollutants from a permanent route-altering switch points installation, in combination with said switch points installation, the system including at least one laterally flexible intermediate elastomeric tubular member located in readily removable, inserted relation beneath portions of said switch points installation, a forced air supply and at least one air directing nozzle, said nozzle being secured in predetermined relation adjacent said switch points, said tubular member being connected in air conducting relation between said air supply and said air nozzle, in use to direct at least one air jet in pollutant-dispersing relation with said switch points to substantially preclude an accumulation of said pollutant and consequent malfunction of said switch points.
A pollutant dispersion system for dispersing air-born pollutants from railroad switch points of a railroad track, in combination with said railroad track switch points, the system including at least one laterally flexible intermediate tubular member, a forced air supply and at least one air directing nozzle, said tubular member being connected in air conducting relation between said air supply and said air directing nozzle, in use to direct at least one air jet in pollutant-dispersing relation with a first working zone, said first working zone containing component portions of said switch points, which are subject to malfunction in the presence of an accumulation of said pollutant, wherein at least one said flexible tubular member extends beneath a stock rail of said railroad track, said switch points operating in conjunction with said track.
A pollutant dispersion system for dispersing air-born pollutants from switch means of a route-changing switch system, in combination with said switch system, the dispersion system including at least one elastomeric tubular intermediate member, a source of forced air, and at least one air directing nozzle, said intermediate tube being located beneath elements of said switch system in air conducting relation between said air source and said air nozzle, in use to direct a continuous air flow in pollutant-dispersing relation with a first working zone, said first working zone including component portions of said switch means that are subject to malfunction in the presence of an accumulation of said pollutant said switch means comprising railroad switch points having at least one rod portion connected thereto, said air directing nozzle being secured adjacent said at least one rod portion, to direct air in pollution dispersing relation, relative to said at least one rod portion.
