Snow blower

A snow blower assembly including a horizontally elongated and laterally opening shroud having one open longitudinal front side and one closed longitudinal rear side as well as opposite end mounting structures at least substantially closing the opposite ends of said shroud, a pair of spiral bladed rotary conveyor members journalled in the opposite end portions of said shroud for simultaneous rotation about an axis extending longitudinally of said shroud, said closed side including a lateral outlet formed therein centrally intermediate said mounting structures and opening rearwardly outwardly of said shroud, a horizontal axial inlet and upwardly opening tangential outlet blower assembly supported relative to said closed side of said shroud and including a rotary impeller registered with said lateral outlet, first and second fluid motors drivingly coupled to said rotary conveyor members and said rotary impeller, each of said first and second fluid motors being of the variable speed type, a pair of opposite end laterally extending horizontal skids carried by opposite ends of said shroud and projecting slightly below the lower periphery of said shroud, rearwardly projecting arm means carried by said shroud, a prime mover including front and rear ends, means pivotally supporting the rear ends of said arm means from said prime mover for angular displacement about a horizontal axis generally paralleling the first mentioned axis, first motor means operatively connected between said arm means and said prime mover for adjustably angularly displacing said arm means relative to said prime mover, said tangential outlet including a horizontally curving outlet head rotatably supported therefrom for rotation about an upstanding axis concentric with said tangential outlet, and second motor means operatively connected between said outlet head and said tangential outlet for adjustably angularly displacing said head relative to said tangential outlet, support means supporting said skids from said shroud for vertical adjustment relative thereto, said support means including fluid motor means for adjustably shifting said skids relative to said shroud.
