Abstract
A snow thrower incorporating a device fixed relative to the auger housing around the auger shaft for generating a downward thrust on the auger shaft which opposes and balances the upward thrust caused on the auger shaft by the cooperation of the auger with the snow. The downward thrust is provided by shaping a portion of the housing for the drive of the auger shaft in such a way so as to create a static downward thrust.
Claims14
A snow thrower comprised of an auger housing defining a forwardly facing opening adapted to engage and receive snow, an auger shaft extending transversely across said auger housing and having a pair of spaced apart auger portions for delivering snow entering said forwardly facing opening toward the center of said auger housing, drive means for driving said auger shaft, the rotation and operation of said auger portions in cooperation with the snow and with said auger housing being effective to create a net upward thrust upon said auger shaft and said auger housing, and means mounted directly to said snow thrower auger shaft and other than said auger housing and said auger portions for cooperating with the snow for effective a downward thrust on said auger shaft and said auger housing in opposition to said spaced thrust.
