Abstract: A method and apparatus for removing snow from roadways and the like includes the provision of a curved scraper blade having top and bottom edges and defining a generally circular passageway forward of the blade extending longitudinally the length of the blade. Forward movement of the blade causes the bottom edge to lift up snow from the roadway and as it is urged into the passageway, pressurized air from an air blower is expelled into the passageway, causing the snow therein to be expelled laterally of the scraper blade and over the roadside. The pressurized air may be expelled into the passageway through one or more apertures in the blade intermediate its ends or alternatively, through an aperture at either end of the blade.
Abstract: A snowthrower comprising a discharge chute having an outer end, a deflector mounted on the outer end of the discharge chute for pivotal movement relative thereto about an axis, and a mechanism for selectively pivoting the deflector relative to the discharge chute, the mechanism including a guide rod having opposite first and second ends, a pin connecting the first end of the guide rod to the deflector at a point spaced from the axis, a compression spring telescoped over the rod and including a first end fixed relative to the discharge chute and a second end fixed relative to the second end of the rod, and a cable for selectively moving the rod in the direction from the second end to the first end.
Abstract: A snow remover to be used in connection with a truck or other suitable vehicle. The apparatus comprises a snow container which moves on the ground scooping up snow like a snow shovel and is provided with at least one spiral conveyor and a discharge pipe. The snow gathered in the snow container by the spiral conveyor is let out through the discharge pipe, which pipe is provided with a choker. The spiral conveyor (3) is installed within the snow container (1) in a vertical position so that only its bottom part (31) is attached to the snow container. The spiral conveyor (3) has a conical form and is fitted within a conical sheath (5). The top part of the sheath thus forms the choker (52), which is connected to the bottom part (41) of the discharge pipe. The discharge pipe (4) has a cross-sectional area larger than that of the choker (52). The discharge pipe (4) is curved, and its radius of curvature (R) is constant. The discharge pipe (4) is formed of two parts, i.e.
Abstract: This invention is a new and unique snow removing apparatus to be fastened upon automotive vehicles, particularly relatively light weight vehicles such as pickup trucks and the like. The invention is characterized by a unique rotary snow pickup mechanism and throwing device together with a non clogging unique design discharge arrangement and wherein the apparatus is powered independently from the vehicle. Instantly removable attachment means and easily controllable height adjustment means are provided in cooperative relationship.
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.

Abstract: A seal (41 or 141) is provided at the pivot joint between a deflector (19) and a snow chute (18) which has spaced fingers (42 or 142) permitting the leading edge of the seal (41 or 141) to conform to a reduced linear dimension when the deflector (19) is pivotal to a forward position of adjustment about its pivot axis (22).
