  • Patent number: 6732818
    Abstract: A device for preserving the orientation of a core is described. A core barrel is attached to a rotatable orienting rod. A plurality of projections are located on an inner surface of the core barrel. Three projections are grouped together and opposite from a fourth projection. A ratchet assembly is included at an end of the rotatable orienting rod opposite from the core barrel. The ratchet assembly includes a first body, to which the rotatable orienting rod is attached, a plate, a second body, and a biasing mechanism. A turning rod is mounted on the plate, which is located between the two bodies. The plate and the second body each have teeth which intermesh, but which slip if a clog in the core barrel inhibits rotation of the rotatable orienting rod.

  • Patent number: 4128134
    Abstract: Method and apparatus for cutting a core in a bore hole and means of marking the core in which a groove is cut into the core along its length and providing an external arm in a definite angular relation to the core marking means and which may be aimed at some particular point so that when the core is removed, the marking on the core will be known to have the orientation with respect to the position that the arm is aimed such, for instance, as possibly a magnetic bearing or any other known reference mark on the surface to which the core may be related.
