  • Fluid shovel apparatus and method
    Patent number: 7823303
    Abstract: A fluid shovel apparatus that pushes and lifts loose material such as snow, leaves, sand, dirt, grass clippings, mulch, or the like. The present invention includes at least one fluid exhaust port extending through a blade. Pressurized fluid is ejected through the at least one fluid exhaust port extending through the blade and ejects towards loose material. The loose material floats on a cushion of pressurized fluid that forms between the blade and the loose material. The loose material is pushed away from the blade and is lifted in an upward direction. Additionally, the fluid shovel apparatus may further include a soft pad and an ice scraper blade to assist in removing material from a surface of a motor vehicle. Additionally, the fluid shovel apparatus may be used to deliver a fire suppressant pressurized fluid upon a material that is burning. Additionally, the fluid shovel apparatus may be used to clear snow from railroad train tracks ahead of a railroad train car.
