Abstract

A hand carriable powered snow removal apparatus having an internal combustion engine power unit removably connected to one end of a tubular boom which supports an elongated drive shaft connected to the engine power takeoff shaft at and to a right angle drive gear unit mounted at the opposite end of the boom. The gear unit includes a housing mounted on the end of the boom and providing a centered drive arrangement for a pair of opposed paddle type impellers mounted on respective ends of an output shaft projecting from opposite sides of the gear housing. A shroud mounted on the gear housing includes an upwardly projecting rear wall and spaced apart lateral side walls partially enclosing the impellers and providing directional control for the snow being discharged from the impellers. A set of movable guide vanes is mounted on the forward end of the shroud and is adjustable to provide for varying the directional attitude of snow being discharged from the shroud. The interior of the rear wall forms a substantially continuous smooth surface which reduces the tendency for snow to accumulate and clog the normal flow path of the snow being discharged by the impellers. A removable scraper bar is mounted on the lower edge of the shroud and also serves as a skid for the apparatus while it is in operation. A handle on the power unit and an adjustable handle on the tubular boom provide for handling and maneuvering the apparatus.
