Abstract
Abstract In an auger mining system which forms an opening in the earth comprising a pair of axially aligned cylindrical holes and wherein the opening has a bottom, the system has a pair of side-by-side conveyors. Each auger conveyor has a shaft and a flight around the shaft which shafts are journaled through bearings at each end to a spacing member and where the spacing members are rigidly tied to each other by a longitudinal member having an underside. A supporting apparatus including a skid is attached to the auger pair and extending to the bottom of the opening. The skid may be attached either to the underside of the longitudinal member or to each of the bearings. If the skids are attached to the bearings, then skids which are on adjacent bearings of mating auger pairs are arcuately staggered to permit side-by-side positioning of the skids.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
In an auger mining system which forms an opening comprising a pair of axially aligned cylindrical holes in the earth, said opening having a bottom, said system having a pair of side-by-side auger conveyors, each auger having a shaft and a flight around said shaft, which shafts are journaled through bearings at each end to a spacing member and wherein said spacing members are rigidly tied to each other by a longitudinal member having an underside and a supporting apparatus comprising an elongated skid means attached to the underside of said longitudinal member of said suger pair and extending to the bottom of said opening.
Claim 2
Dependent Claim
105 words
In an auger mining system which forms an opening comprising a pair of axially aligned cylindrical holes in the earth, said opening having a bottom, said system having a pair of side-by-side auger conveyors, each auger having a shaft and a flight around said shaft, which shafts are journaled through bearings at each end to a spacing member and wherein said spacing members are rigidly tied to each other by a longitudinal member having an underside and a supporting apparatus comprising an elongated skid means attached to the underside of said longitudinal member of said suger pair and extending to the bottom of said opening.
Claim 3
Dependent Claim
90 words
In a pair of side-by-side auger conveyors for conveying material from a longitudinal opening having a bottom, each auger having a shaft journaled at each end to a spacer member, a longitudinal member rigidly attached to said spacer members and extending longitudinally between pairs of augers and flights along the length of said shaft, a support means attached to said longitudinal member at each end thereof and extending toward the bottom of said longitudinal opening by an amount to position said flights away from the bottom of said longitudinal opening.
Claim 4
Dependent Claim
90 words
In a pair of side-by-side auger conveyors for conveying material from a longitudinal opening having a bottom, each auger having a shaft journaled at each end to a spacer member, a longitudinal member rigidly attached to said spacer members and extending longitudinally between pairs of augers and flights along the length of said shaft, a support means attached to said longitudinal member at each end thereof and extending toward the bottom of said longitudinal opening by an amount to position said flights away from the bottom of said longitudinal opening.
Claim 5
Dependent Claim
63 words
In an apparatus as defined in claim 2 wherein said longitudinal opening includes a pair of substantially cylindrical side-by-side horizontal holes having a cusp between said holes forming the bottom of said opening and wherein said support means comprises a plurality of aligned skid means riding on said cusp and a support member attached between each said skid means and said longitudinal member.
Claim 6
Dependent Claim
29 words
An apparatus as defined in claim 3 wherein said skid means comprises a pair of short shoes attached under said spacer means and riding on top of said cusp.
Claim 7
Dependent Claim
130 words
In a pair of side-by-side auger conveyors for conveying material from a longitudinal opening having a bottom, said longitudinal opening including a pair of substantially cylindrical side-by-side horizontal holes having a cusp between said holes and forming the bottom of said opening, each said auger having a shaft journaled at each end to a spacer member, a longitudinal member rigidly attached to said spacer members and between pairs of augers and flights along the length of said shaft, a support means attached to said longitudinal member and extending toward the bottom of said longitudinal opening by an amount to position said flights away from the bottom of said longitudinal opening, said support means including a tubular member extending the length of said longitudinal member in supporting contact with said cusp.
Claim 8
Dependent Claim
130 words
In a pair of side-by-side auger conveyors for conveying material from a longitudinal opening having a bottom, said longitudinal opening including a pair of substantially cylindrical side-by-side horizontal holes having a cusp between said holes and forming the bottom of said opening, each said auger having a shaft journaled at each end to a spacer member, a longitudinal member rigidly attached to said spacer members and between pairs of augers and flights along the length of said shaft, a support means attached to said longitudinal member and extending toward the bottom of said longitudinal opening by an amount to position said flights away from the bottom of said longitudinal opening, said support means including a tubular member extending the length of said longitudinal member in supporting contact with said cusp.
