Claim 3

A drilling apparatus according to claim 1 wherein said container comprises a box-like structure having a closed bottom, and said container means has closure comprising a wall section of said container movably mounted thereon and movable between a closed position, and an open position wherein it defines an opening for discharge of spoil from the container.

Claim 4

A drilling apparatus comprising: an auger for drilling a hole in the ground; leads extending parallel to and supporting said auger, and means for guiding said auger to move longitudinally of said leads during drilling; drive means for rotating said auger and for moving said auger longitudinally of said leads; a container for receiving spoil produced by said auger during drilling, said container being guided on a lower end of said leads, and being a box-like structure having a closed bottom and a closure means constituted by a wall section movably mounted on said box-like structure and movable between a closed position and an open position wherein it defines an opening for discharge of spoil from the container, said auger extending through said container; and discharging means in said container comprising a displacable wall movable from a retracted position opposite said wall section to an advanced position adjacent said wall section to displace spoil from said container through said opening.

Claim 5

A drilling apparatus comprising: an auger for drilling a hole in the ground; leads extending parallel to and supporting said auger, and means for guiding said auger to move longitudinally of said leads during drilling; drive means for rotating said auger and for moving said auger longitudinally of said leads; a container for receiving spoil produced by said auger during drilling, said container being guided on a lower end of said leads, and being a box-like structure having a closed bottom and a closure means constituted by a wall section movably mounted on said box-like structure and movable between a closed position and an open position wherein it defines an opening for discharge of spoil from the container, said auger extending through said container; and discharging means in said container comprising a displacable wall movable from a retracted position opposite said wall section to an advanced position adjacent said wall section to displace spoil from said container through said opening.

Claim 6

A drilling apparatus according to claim 3 wherein said container is integral with a mounting structure guided on said leads, actuator means for moving said displaceable wall between the advanced and retracted positions comprising hydraulic piston and cylinder assemblies connected to act between said displaceable wall and said mounting structure.

Claim 7

A drilling apparatus according to claim 3 wherein said auger extends through the container in a tubular guide formed on one side by said mounting structure and on the other side by said displaceable wall.

Claim 8

A drilling apparatus according to claim 3 wherein said auger extends through the container in a tubular guide formed on one side by said mounting structure and on the other side by said displaceable wall, the side of the tubular guide formed by the mounting structure having an upper edge positioned above the upper edge of the other side.

Claim 9

A drilling apparatus according to claim 4 wherein said hydraulic piston and cylinder assemblies are received in tubular casings in said displaceable wall having closed ends extending towards said wall section, such that in operation said closed ends engage and move said wall section to the open position as the displaceable wall is moved towards the advanced position.

Claim 10

A drilling apparatus comprising: an auger for drilling a hole in the ground; leads extending parallel to and supporting said auger, and means for guiding said auger to move longitudinally of said leads during drilling; drive means for rotating said auger and for moving said auger longitudinally of said leads; a container for receiving spoil produced by said auger during drilling, said container being carried upon said leads to receive spoil removed from said hole by the auger, said auger extending through said container and said container comprising a box-like structure having a closed bottom, closure means comprising a wall section of said container movably mounted thereon and movable between a closed position, and an open position wherein it defines an opening for discharge of spoil from the container, and discharging means comprising a displaceable wall movable from a retracted position opposite to said wall section to an advanced position adjacent said wall section to displace spoil from said container through said opening.

Claim 11

A drilling apparatus comprising: an auger for drilling a hole in the ground; leads extending parallel to and supporting said auger, and means for guiding said auger to move longitudinally of said leads during drilling; drive means for rotating said auger and for moving said auger longitudinally of said leads; a container for receiving spoil produced by said auger during drilling, said container being carried upon said leads to receive spoil removed from said hole by the auger, said auger extending through said container and said container comprising a box-like structure having a closed bottom, closure means comprising a wall section of said container movably mounted thereon and movable between a closed position, and an open position wherein it defines an opening for discharge of spoil from the container, and discharging means comprising a displaceable wall movable from a retracted position opposite to said wall section to an advanced position adjacent said wall section to displace spoil from said container through said opening.

Claim 12

A drilling apparatus according to claim 8 wherein said container is integral with a mounting structure guided on said leads, actuator means for moving said displaceable wall between the advanced and retracted positions comprising hydraulic piston and cylinder assemblies connected to act between said displaceable wall and said mounting structure.

Claim 13

A drilling apparatus according to claim 8 wherein said auger extends through the container in a tubular guide formed on one side by said mounting structure and on the other side by said displaceable wall.

Claim 14

A drilling apparatus according to claim 8 wherein said auger extends through the container in a tubular guide formed on one side by said mounting structure and on the other side by said displaceable wall, the side of the tubular guide formed by the mounting structure having an upper edge positioned above the upper edge of the other side.

Claim 15

A drilling apparatus according to claim 9 wherein said hydraulic piston and cylinder assemblies are received in tubular casings in said displaceable wall having closed ends extending towards waid wall section, such that in operation said closed ends engage and move said wall section to the open position as the displaceable wall is moved towards the advanced position.
