Abstract:
A three-stage snow thrower having a housing, a power supply operatively connected to said housing, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending rotatably attached to opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The power supply drives the longitudinal drive shaft, thereby causing the longitudinal drive shaft to rotate, and at least a portion of such rotation is transferred to the lateral drive via a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft, wherein the first stage assembly pushes loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft, wherein the second stage assembly pushes the snow from the first stage assembly axially rearward in a transverse manner relative to the first stage assembly. The third stage assembly includes an impeller that rotates to throw the snow from the second stage assembly through a chute attached to the housing to expel the snow from the housing.

Claim (Index 15):
A multiple-stage snow thrower for removing accumulated snow, said multiple-stage snow thrower having a housing, a frame, and a power supply operatively connected to said frame, said multiple-stage snow thrower comprising:\n a first stage assembly operatively connected to said power supply for receiving rotational power therefrom, wherein rotation of said first stage assembly moves said snow radially to expel said snow from said housing, and wherein said first stage assembly is rotatable about a first axis; a second stage assembly, wherein rotation of said second stage assembly moves said snow longitudinally toward said first stage assembly, and wherein said second stage assembly is rotatable about said first longitudinal axis; and a third stage assembly operatively connected to said power supply, wherein rotation of said third stage assembly moves said snow laterally toward said second stage assembly, and wherein said third stage assembly is rotatable about a second axis, said first and second axes are oriented at an angle relative to each other; wherein said snow is moved from said third stage toward said second stage assembly and from said second stage assembly toward said first stage assembly without ram induction
