  • Patent number: 4081161
    Abstract: A heater is provided to supply hot air through apertured distribution ducts at a rate of at least 1300 CFM, a temperature of at least 250.degree. F, and a velocity of at least 3000 FPM so as to clear the entire switch area of ice, snow and water. The parallel, spaced distribution ducts are apertured so as to direct the air not only outwardly toward the rails but also inwardly to clear the central portion of the rail grade. The switch grade is therefore kept dry and the movable rails are free to be shifted when required.
