Abstract
The snow thrower includes an impeller housing carrying an impeller for rotation about a transverse axis and having an upwardly open, forwardly inclined discharge chute through which snow is propelled by the impeller. One or more upwardly extending deflector vanes are disposed in the discharge chute for directing the discharge of snow. Each deflector vane includes a pivot pin which extends rotatably through the transverse rear wall of the discharge chute and a control mechanism, located exteriorly of the discharge chute and connected to the outer ends of the pivot pins, is operable to selectively pivot the deflector vanes between forward, left and right discharge positions.
Claims9
A snow thrower comprising a housing carrying an impeller for rotation about a transverse axis and having an upwardly open discharge chute disposed above said impeller and including a transverse rear wall, at least one deflector vane disposed in said discharge chute for directing the discharge of snow propelled upwardly through said discharge chute by said impeller, means pivotally mounting said deflector vane on said rear wall for free pivotal movement between forward, left and right discharge positions, said mounting means including a pivot pin extending from said deflector vane and rotatably through said rear wall and having an end rearwardly of said rear wall, and a control mechanism located exteriorly of said discharge chute and including means located rearwardly of said rear wall and connected to said pivot pin end for rotation thereof so as to selectively pivot said deflector vane between said positions.
A snow thrower comprising a housing carrying an impeller for rotation about a transverse axis and having an upwardly open discharge chute disposed above said impeller and including a transverse rear wall, at least one deflector vane disposed in said discharge chute for directing the discharge of snow propelled upwardly through said discharge chute by said impeller, means pivotally mounting said deflector vane on said rear wall for free pivotal movement between forward, left and right discharge positions, said mounting means including a pivot pin extending from said deflector vane and extending rotatably through said rear wall, and a control mechanism located exteriorly of said discharge chute and connected to said pivot pin for selectively pivoting said deflector vane between said positions, said control mechanism including an actuating member mounted for reciprocative movement in a direction generally parallel to the rotational axis of said impeller, a connecting arm having one end connected to said pivot pin for common rotation therewith and an opposite end connected to said actuating member, whereby said deflector vane is rotated between said positions in response to reciprocative movement of said actuating member, and means for selectively reciprocating said actuating member.
