Method and apparatus for removing material from a hole in a strata for use in forcing a member into material comprising or underlying this strata
First Claim
1. An apparatus for removing material from a hole in a strata comprising:
- a) a drive shaft rotatably mounted within a housing and having a cutting blade mounted on one end thereof for removing material from a hole in a strata, the other end of said drive shaft being adapted for engaging power means for rotating said drive shaft;
b) a locating means mounted on the outside surface of said housing and having means extending therefrom for supporting said housing over the hole with the cutting blade extending into the hole to a location which can be changed by movement of said locating means relative to said housing; and
c) means for selectively preventing movement of said locating means relative to said housing to maintain the cutting blade at a location in the hole.

Abstract
An apparatus for forcing a member or device, such as a sample tube or seismic or geological instrument, through a material such as soil along a selected line of action. The apparatus includes a derrick with first and second plates mounted thereto, the second plate having a locking dog extending through a hole therein for engaging the material, and the first plate being provided with a hydraulic cylinder or other device for forcing the member through the material. The first plate is also provided with an extruder head for releasably mounting the sample-containing sample tube thereto, and the hydraulic cylinder is provided with a plunger releasably mounted to the ram thereof for extruding the sample from the sample tube. The locking dog positively engages the material to provide an apparatus for transmitting the reactive forces resulting from forcing the member through the material to the material. The outer surface of the locking dog is shaped to approximate the shape of the hole and the locking dog is provided with a radially extensible member for engaging a discontinuity or groove in the wall of the hole to transmit the reactive force exerted by the force exerting apparatus to the material. Also provided is an apparatus for removing material from a wall of the hole through the material and a method of sampling the material under a strata.

12. A method of forcing a member into a material comprising the steps of:
-
a) drilling a hole in a material; b) creating a discontinuity in the hole; c) engaging the discontinuity with a tubular member having a bore therethrough; d) forcing a member into the hole through the bore in the tubular member and into the material; and e) transmitting the reactive forces resulting from the resistance of the material to the forcing of the member into the discontinuity in the material through the tubular member. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus for removing material from a hole in a strata comprising:
-
an elongate, rotatable member having means mounted on one end thereof for removing material comprising a strata from the wall of a hole in the strata, the other end of said rotatable member being adapted for engaging means for rotating said rotatable member; means mounted to said rotatable member comprising a generally round housing having threads formed on the outside surface thereof and a threaded lug which is moved relative to said rotatable member on the threads for supporting said rotatable member over the hole in the strata with the material removing means extending into the hole to a location selected by moving said supporting means relative to said rotatable member; and means for preventing movement of said supporting means relative to said rotatable member to maintain the material removing means at the selected location in the hole. - View Dependent Claims (19, 20, 21, 22, 23)

24. An apparatus for removing material from a hole in a strata comprising:
-
an elongate, rotatable member having means mounted on one end thereof for removing material comprising a strata from the wall of a hole in the strata, the other end of said rotatable member being adapted for engaging means for rotating said rotatable member; a support comprised of a housing having said rotatable member journaled therein and a lug carried on the outside surface of said housing and selectively positionable thereon for supporting said rotatable member over the hole in the strata with the material removing means extending into the hole to a location selected by moving said lug relative to said housing; and means for preventing movement of said lug relative to said housing to maintain the material removing means at the selected location in the hole. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A method of removing a material comprising a strata from a surface from within a hole in the strata comprising the steps of:
-
supporting a material removing means on the surface of the strata at a selected location in a hole in a strata; sliding the material removing means on the surface of the strata to engage the selected location within the hole from which material is to be removed; and preventing movement of the material removing means which would change the selected location at which material is removed. - View Dependent Claims (32, 33, 34, 35)
