US Patent 7624521 Snowthrower chute control

A snowthrower has a rotatable chute that directs the snow stream in different directions depending on the rotational position of the chute. A slidable hand grip is mounted on one of the handle tubes of the snowthrower. The hand grip can be slid down the handle tube by the operator to rotate the chute in a first direction. The hand grip can be slid up the handle tube by the operator to rotate the chute in a second opposite direction. The hand grip includes a rounded knob that the operator can grip with one hand. A latch is provided to lock the hand grip in an adjusted position on the handle tube.
