Abstract
Abstract A device having an auger shaft connected to a frame. A motor platform is mounted on the threaded shaft and moves therewith while supporting a finger-shaped soil-sampling receptacle embracing the auger portion of the auger shaft. The soil-sampling receptacle is maintained in yieldable engagement against the ground around the auger shaft and receives the soil sample which moves through a sleeve extending through the space between the finger-shaped receptacle whereupon the soil sample empties downwardly into the receptacle. Limit switches are provided to stop the operation of the unit at predetermined points in its upward and downward travel. The soil-sampling unit is adjustably mounted on the side of a pickup truck and is powered by the truck battery.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
147 words
A device for sampling soil, comprising, a frame, a soil-sampling tool carried on a shaft threadably connected to said frame for moving said tool upwardly and downwardly relative to the ground, power means for rotating said shaft, a soil-sampling receptacle having a top access opening associated with said tool for receiving said sample, said tool extending vertically closely adjacent said receptacle and retaining means provided around said tool to hold a soil sample on said tool until the soil sample has moved upwardly to a point of communication with the access opening in said receptacle whereupon said soil sample is emptied into said receptacle through said access opening, and said receptacle is positioned in a support enclosure including said retaining means, said support enclosure being movably disposed longitudinally of said soil-sampling tool for maintaining engagement with the ground when said tool is in engagement with the ground.
Claim 2
Independent Claim
147 words
A device for sampling soil, comprising, a frame, a soil-sampling tool carried on a shaft threadably connected to said frame for moving said tool upwardly and downwardly relative to the ground, power means for rotating said shaft, a soil-sampling receptacle having a top access opening associated with said tool for receiving said sample, said tool extending vertically closely adjacent said receptacle and retaining means provided around said tool to hold a soil sample on said tool until the soil sample has moved upwardly to a point of communication with the access opening in said receptacle whereupon said soil sample is emptied into said receptacle through said access opening, and said receptacle is positioned in a support enclosure including said retaining means, said support enclosure being movably disposed longitudinally of said soil-sampling tool for maintaining engagement with the ground when said tool is in engagement with the ground.
Claim 3
Dependent Claim
14 words
The structure of claim 1 wherein said frame is carried on a mobile vehicle.
Claim 4
Dependent Claim
18 words
The structure of claim 1 wherein said tool is an auger and said retaining means is a sleeve.
Claim 5
Dependent Claim
73 words
The structure of claim 1 wherein said actuating means are associated with said shaft and limit switches are operatively connected to said power means and engageable by said actuating means at the end of predetermined distances of travel of said tool up and down respectively, and means associated with said power means and said limit switches for deactivating said power means upon one of said limit switches being actuated by said actuating means.
Claim 6
Dependent Claim
24 words
