Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A sampling device for solid material in an aggregate form comprising, in combination: a guide sleeve having one end open and having a conduit from said guide sleeve near the other end, the conduit being in a plane substantially perpendicular to the longitudinal axis of the guide sleeve; a sample-withdrawing auger rotatably mounted within the guide sleeve and adapted to move longitudinally with respect to the guide sleeve, the auger having a shaft portion extending from one end thereof, the other end of the auger being positioned in and extendible from the open end of the guide sleeve to pull material into the sleeve; first means connected to the shaft portion of said auger for rotating the auger; and second means for moving said auger longitudinally in two directions into and out of contact with the aggregate material being sampled, said second means being connected to said first means.
Claim 2
Dependent Claim
149 words
A sampling device for solid material in an aggregate form comprising, in combination: a guide sleeve having one end open and having a conduit from said guide sleeve near the other end, the conduit being in a plane substantially perpendicular to the longitudinal axis of the guide sleeve; a sample-withdrawing auger rotatably mounted within the guide sleeve and adapted to move longitudinally with respect to the guide sleeve, the auger having a shaft portion extending from one end thereof, the other end of the auger being positioned in and extendible from the open end of the guide sleeve to pull material into the sleeve; first means connected to the shaft portion of said auger for rotating the auger; and second means for moving said auger longitudinally in two directions into and out of contact with the aggregate material being sampled, said second means being connected to said first means.
Claim 3
Dependent Claim
14 words
The sampling device of claim 1 wherein the first means is an electric motor.
Claim 4
Dependent Claim
15 words
The sampling device of claim 1 wherein the second means is an electro-hydraulic linear actuator.
Claim 5
Dependent Claim
69 words
The sampling device of claim 1 further including a traveling sleeve interposed between the guide sleeve and the auger, the traveling sleeve having at least one longitudinal key slot on its outside diameter to mate with at least one key provided in the guide sleeve, the traveling sleeve being further maintained in a fixed relationship to the auger such that the auger and traveling sleeve move in unison longitudinally.
