Abstract

Abstract A flexible shaft is connected directly to the crank shaft of a snowmobile engine by a coupler. The flexible shaft drives a reduction gear which is enclosed in a hand-held housing. The reduction gear rotates a drive shaft at a substantially reduced speed and the drive shaft connects to the ice auger bit through a coupler which allows disengagement of the bit when no downward pressure is applied to the housing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 207 words
A hand-held auger powered by a remotely located engine, the combination comprising: a flexible shaft; first coupling means fastened to one end of the flexible shaft for attaching it to a rotating shaft on said engine; a housing having an opening which receives the other end of said flexible shaft; gear reduction means disposed in said housing and including a drive shaft which is coupled for rotation by said flexible shaft at a substantially reduced rate therefrom; an auger bit; and second coupling means for connecting the auger bit to said drive shaft, said second coupling means including: an auger extension shaft which is rotatably mounted to said housing and extends through a second opening therein to connect with said auger bit, said auger extension shaft also being mounted for translational motion between an engaged position in which it couples to said drive shaft for rotation thereby and a disengaged position in which it is decoupled from said drive shaft; a bias spring which urges said auger extension shaft into its disengaged position; and a handle which is disposed around said auger extension shaft and beneath said housing, said handle being restrained from motion along the axis of said auger extension shaft but being freely rotatable thereabout.
Claim 2
Dependent Claim 207 words
A hand-held auger powered by a remotely located engine, the combination comprising: a flexible shaft; first coupling means fastened to one end of the flexible shaft for attaching it to a rotating shaft on said engine; a housing having an opening which receives the other end of said flexible shaft; gear reduction means disposed in said housing and including a drive shaft which is coupled for rotation by said flexible shaft at a substantially reduced rate therefrom; an auger bit; and second coupling means for connecting the auger bit to said drive shaft, said second coupling means including: an auger extension shaft which is rotatably mounted to said housing and extends through a second opening therein to connect with said auger bit, said auger extension shaft also being mounted for translational motion between an engaged position in which it couples to said drive shaft for rotation thereby and a disengaged position in which it is decoupled from said drive shaft; a bias spring which urges said auger extension shaft into its disengaged position; and a handle which is disposed around said auger extension shaft and beneath said housing, said handle being restrained from motion along the axis of said auger extension shaft but being freely rotatable thereabout.
Claim 3
Dependent Claim 49 words
The hand-held auger as recited in claim 1 in which said second coupling means includes a drive element on said drive shaft which mates with a driven element on said auger extension shaft to impart rotary motion thereto when the auger extension shaft is disposed in its engaged position.
