摘要： A booster seat is provided which has two different booster heights and two corresponding seat sizes, and is capable of nesting in a second booster seat. The booster seat has two chairs portions each having a seat surface, a back support and two arm supports which define seat pockets. The first chair portion seat surface, back support and arm supports are smaller than the second chair portions seat surface, back and arm supports. The first chair portions has an outer circumference defined by its back support and arm supports which is small enough to nest in the second seat pocket. Both the first chair portion and the second chair portion are able to act as bases, and are connected to each other such that the first chair portions acts as a base for the second chair portion and the second chair portion acts as a base for the first chair portion.

摘要： 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.
