A device for automatically carrying out the withdrawal and deposition of core samples of semi-solid media in which one or more hollow punches are mounted for movement in three mutually perpendicular directions, so that the punch can be brought above and lowered into the media, a vacuum applied to suck the media into a chamber in the punch, the punch then being raised and moved to a position above a second media, the vacuum then being removed and compressed air applied after the punch has been lowered over the other media, thereby to push the sample removed from the first media from the punch. The operations can all be controlled automatically.

A device for automatically carrying out the withdrawal and deposition of core samples of semi-solid media, said device comprising: (a) a carrier; (b) three separate guide means extending in three mutually perpendicular directions and mounting said carrier and guiding said carrier for accurate reciprocable movement in said three mutually perpendicular directions in a controlled manner; (c) a holder mounted on said carrier; (d) at least one hollow punch mounted on said holder, said at least one punch defining, in its interior, a punch chamber having a lower bevelled cutting edge; (e) a bore through said punch, communicating with said chamber, the diameter of said bore being less than the diameter of said chamber; (f) a compressed air source; (g) a vacuum generator; (h) means selectively connecting said bore to said compressed air source or said vacuum generator; and (i) control means governing the movement of said carrier and of said selecitve means, whereby the hollow punch may be raised from the bottom of the receptacle, and immediately thereafter carryout a horizontal shift in two mutually perpendicular directions, enabling air to penetrate under the core sample.
