Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
Apparatus comprising rotary cutting means for rotatably penetrating a surface, conduit means associated with said cutting means, said cutting means being rotatably mounted on shaft means, said cutting means having edge means extending therefrom and adapted to cut through a surface, said edge means being pitched sufficiently to propel said cutting means and said conduit means as said cutting means is rotated, impeller means operatively associated with said cutting means for rotating said cutting means, said conduit means being arranged to cause a fluid to impinge against said impeller means and thereby rotate said impeller means, said shaft means being mounted in a hollow housing, said conduit means operatively connected to said housing, opening means being provided in said housing next adjacent said cutting means for leading a fluid from said cutting means to said conduit means, said opening means having cap means thereon for partially blocking said opening means said cap means being movable on said housing to change the location of said opening means which may be blocked by said cap means.
Claim 2
Dependent Claim
174 words
Apparatus comprising rotary cutting means for rotatably penetrating a surface, conduit means associated with said cutting means, said cutting means being rotatably mounted on shaft means, said cutting means having edge means extending therefrom and adapted to cut through a surface, said edge means being pitched sufficiently to propel said cutting means and said conduit means as said cutting means is rotated, impeller means operatively associated with said cutting means for rotating said cutting means, said conduit means being arranged to cause a fluid to impinge against said impeller means and thereby rotate said impeller means, said shaft means being mounted in a hollow housing, said conduit means operatively connected to said housing, opening means being provided in said housing next adjacent said cutting means for leading a fluid from said cutting means to said conduit means, said opening means having cap means thereon for partially blocking said opening means said cap means being movable on said housing to change the location of said opening means which may be blocked by said cap means.
Claim 3
Dependent Claim
65 words
The apparatus of claim 1 where said conduit means comprises a flexible conduit having opposed flexible wire means mounted thereon, said wire means lying in a common plane to prevent said conduit means from being flexed in the direction in which said plane extends and for allowing said conduit to be flexed in a direction substantially transverse to the direction in which said plane extends.
Claim 4
Dependent Claim
32 words
The apparatus of claim 1 where said conduit means extends through substantially rigid tube means having conduit influent and conduit effluent openings arranged for changing the direction in which said conduit projects.
Claim 5
Dependent Claim
24 words
The apparatus of claim 2 where said conduit means extends through substantially rigid tube means for changing the direction in which said conduit projects.
Claim 6
Dependent Claim
47 words
The apparatus of claim 1 where said cap means comprises rotary shield means mounted on an axle to partially block said opening means, weight means extending from said shield means below said axle to position said shield means above the center of gravity of said weight means.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 where said impeller means are mounted on said shaft means for applying torque to said shaft means.
Claim 8
Dependent Claim
47 words
The apparatus of claim 6 where said conduit means is operatively associated with said cutting means and said impeller means to lead a fluid away from said cutting means and to impinge against said impeller means to apply torque to said shaft means through said impeller means.
