20130291411 | THREE-STAGE SNOW THROWER - A three-stage snow thrower having a housing, a power supply, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending between opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft for pushing loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft for pushing snow from the first stage assembly axially rearward. The third stage assembly includes an impeller that rotates to throw the snow through a chute attached to the housing to expel the snow from the housing. | 11-07-2013 |
20130291412 | TWO-STAGE SNOW THROWER - A two-stage snow thrower for removing and throwing accumulated snow. The two-stage snow thrower includes a housing, a power supply, a longitudinal drive shaft extending from the power supply, and a lateral drive shaft extending transversely relative to the longitudinal drive shaft. A first stage assembly includes at least one auger is positioned immediately adjacent to each opposing sides of the gear assembly which receives both the longitudinal and lateral drive shaft. The first stage assembly pushes loosened snow axially toward the gear assembly. A second stage assembly includes an impeller that centrifugally throws the snow from the housing through a chute extending from the housing. A paddle is attached to each of the augers of the first stage assembly, and the paddles push the snow rearwardly toward the impeller. | 11-07-2013 |
20140360057 | THREE-STAGE SNOW THROWER - 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. | 12-11-2014 |
