  • Geophone implanting and positioning apparatus
    Patent number: 4838379
    Abstract: An apparatus for implanting and positioning a geophone assembly into the earth is disclosed. The geophone implanting apparatus includes a receptacle for receiving and retaining a geophone assembly. A magnetic compass and a cylindrical bubble level are mounted concentrically approximately one meter from the receptacle so that the ferromagnetic properties of the geophone do not induce errors in the azimuth measurement. A pair of radially disposed handles are utilized to rotationally manipulate the geophone into a proper orientation during implantation. After the geophone assembly has been implanted and leveled a release mechanism is utilized to release the geophone from the receptacle by deforming a spring grip mechanism which is utilized to retain the geophone. In the depicted embodiment, a geophone assembly having a radially non-symmetric case is utilized in conjunction with a matching receptacle so that a unique orientation of the geophone may be accomplished.
