Claim 5

An inspection kit for testing the condition of a wooden body below the surface of the ground comprising: a straight metal tube having a length sufficient to extend from the body at the position to be tested upwardly to a position above the ground, the end faces of the tube lying transversely to its axis, a drive rod having a pointed end member closely fitting within the tube and slidable within the tube and extending beyond the lower end thereof, said rod having a shoulder at its upper end adapted to lie in engagement with the upper end face of said tube when said pointed member protrudes from the other end thereof, whereby said tube is adapted to be driven through the earth by blows against said rod into position against the wooden body with said pointed end and a portion of the adjacent end of said tube penetrating the body and said rod is adapted to be withdrawn leaving said tube in position in the ground to receive a boring tool or the like for producing a test sample of the wood of the body in alignment with the tube, a tamping rod for insertion within said tube and having a head adapted to engage a filler plug for filling the hole after removal of the sample whereby a treated wooden plug having a diameter to fit the bored hole may be inserted in the tube and thereafter tamped into place with said rod.

Claim 6

An inspection kit as set forth in claim 3 wherein the outer surface of the end of the tube adjacent said pointed end is tapered in general alignment with the slope of said pointed end to facilitate the driving of the end of said tube into the wooden body.

Claim 7

An inspection kit for testing the condition of a wooden body below the surface of the ground comprising: a straight metal tube having a length sufficient to extend from the body at the position to be tested upwardly to a position above the ground, the end faces of the tube lying transverseley to its axis, a drive rod having a pointed end member closely fitting within the tube and slidable within the tube and extending beyond the lower end thereof, said rod having a shoulder at its upper end adapted to lie in engagement with the upper face of said tube when said pointed member protrudes from the other end thereof, whereby said tube is adapted to be driven through the earth by blows against said rod into position against the wooden body with said pointed end and a portion of the adjacent end of said tube penetrating the body and said rod is adapted to be withdrawn leaving said tube in position in the ground to receive a boring tool or the like for producing a test sample of the wood of the body in alignment with the tube, said means for turning said bit including a shaft adapted to be attached to said bit and rotatably and slidably movable within said tube and of a length to extend from the shank of said bit to a position outside said tube, and a cross handle adapted to be secured to said shaft for turning said shaft and the bit.

Claim 8

An inspection kit for testing the condition of a wooden body below the surface of the ground comprising: a straight metal tube having a length sufficient to extend from the body at the position to be tested upwardly to a position above the ground, the end faces of the tube lying transverseley to its axis, a drive rod having a pointed end member closely fitting within the tube and slidable within the tube and extending beyond the lower end thereof, said rod having a shoulder at its upper end adapted to lie in engagement with the upper face of said tube when said pointed member protrudes from the other end thereof, whereby said tube is adapted to be driven through the earth by blows against said rod into position against the wooden body with said pointed end and a portion of the adjacent end of said tube penetrating the body and said rod is adapted to be withdrawn leaving said tube in position in the ground to receive a boring tool or the like for producing a test sample of the wood of the body in alignment with the tube, said means for turning said bit including a shaft adapted to be attached to said bit and rotatably and slidably movable within said tube and of a length to extend from the shank of said bit to a position outside said tube, and a cross handle adapted to be secured to said shaft for turning said shaft and the bit.

Claim 9

An inspection kit as set forth in claim 5 wherein the outer surface of the end of the tube adjacent said pointed end is tapered in general alignment with the slope of said pointed end to facilitate the driving of the end of said tube into the wooden body.

Claim 10

An inspection kit as set forth in claim 5 or 6 wherein said shaft is of square cross section and said handle has a transverse hole of square cross section for fitting said shaft and for turning said bit, and wherein said bit has a portion of square cross section at its connecting end adapted to be engaged by the inner wall of said shaft to afford positive rotation of said bit by said shaft.

Claim 11

An inspection kit as set forth in claim 5 or 6 wherein said handle has a second transverse hole of square cross section for fitting said bit portion whereby said handle is adapted to be used directly with said bit to turn said bit for taking a sample of the wood from an exposed area of a wooden body.
