Abstract: Sample gathering apparatus for drivably moving a core sampling assembly into and out of subterranean zones for gathering core samples therewithin, with the apparatus including an elongated frame means which is adapted for adjustable pivotal mounting upon a supporting vehicle. Drive means are provided for delivering power to the core sampling assembly, and coupling means are further provided for releasably securing the drive means to the core sampling assembly. The core sampling assembly is arranged to be driven vertically into the subterranean zones to be sampled, and the coupling means which releasably secures the drive means to the core sampling assembly permits pivotal motion of the core sampling assembly about a generally horizontal axis so as to permit pivotal lifting of the core sampling assembly from the ground surface for easy removal of the sample retained therewithin.
