Abstract
Abstract Apparatus for removing snow from the surface of a roadway to a disposal site as the roadway vehicle advances and scoops up the snow into a storage chamber. A primary conduit engaging the road surface coupled with a secondary conduit together carry the snow into the storage chamber. The secondary conduit, blower and worm provide means to compensate for variations in vehicle speed and conditions of the snow on the road surface. The snow may be melted at the chamber to economize space and provide easy evacuation of the chamber by a steam generator or flame thrower mounted in the vehicle.
