Abstract
A snow thrower head comprises an impeller and an auger disposed within a housing. The impeller is to contact a surface to be cleared by the impeller. The impeller is rotatable within the housing about a first axis while the auger is rotatable within the housing about a second axis above and forward the first axis.
Claims26
A single-stage snow thrower comprising:
- a prime mover;
- a discharge chute;
- a housing defining a volume, the volume comprising a portion contained underneath the discharge chute, the housing further defining a forward opening in front of and transversely extending across the portion of the volume and through which snow may pass into the portion of the volume;
- an impeller disposed within the portion of the volume of the housing underneath the discharge chute, the impeller operably coupled to the prime mover and rotatable within the housing about a first axis;
- an auger disposed within the housing in front of the discharge chute and rotatable within the housing about a second axis parallel to, above and forward the first axis.

A snow thrower header comprising:
- a housing;
- a discharge chute extending from the housing;
- an impeller underneath the discharge chute and disposed within the housing so as to contact an underlying terrain to be cleared by the impeller, the impeller rotatable within the housing about a first axis to lift snow from the underlying terrain and impel the snow directly into the discharge chute;
- an auger disposed within the housing and rotatable within the housing about a second axis above and forward the first axis.
1 more element
A method comprising:
- rotatably driving an impeller underneath a discharge chute about a first axis and in direct contact with terrain underlying snow to be lifted from the underlying terrain and to directly impel the snow into and through the discharge chute;
- and
- rotatably driving an auger about a second axis parallel to, above and forward the first axis to move the snow towards the impeller.
A single-stage snow thrower comprising:
- a prime mover;
- a housing;
- a discharge chute;
- an impeller disposed within the housing underneath the discharge chute, the impeller operably coupled to the prime mover and rotatable within the housing about a first axis;
- an auger disposed within the housing and rotatable within the housing about a second axis parallel to, above and forward the first axis, wherein the housing has opposing side walls, the housing defining a single uninterrupted interior volume containing both the impeller and the auger, wherein the auger overlies a continuous uninterrupted empty volume bounded by a bottom of the auger, a front of the housing and a front of the impeller.
