  • the said member is of tubular form, open at both ends, and the cross-sectional areas of its bore regions are concentric with the central axis of the member.
  • a second member extends from that end of the first member remote from the leading end thereof, concentric with the axis of said first member, and said second member has an internal diameter greater than the internal diameter of the regions of the first member iimiediately adjacent thereto.
  • the said second member has an aperture formed in one side thereof whilst in another embodiment the said second member defines two diametrically opposite apertures.
  • the axial length of the, or each, aperture is equal to or greater than the axial length of said first element and the width of the, or each, aperture is equal to or greater than the diameter of the bore of the first member immediately adjacent to said second member.
  • the aperture, or apertures, in the second member facilitate removal of a core pushed into the second member from the first member.
  • said second member is formed integral with said first member but in an alternative embodiment said first and second members may be formed independently and provided with means for interlocking them into substantially rigid association.

  • the external diameter of the member 11, being smaller than the external diameter of the ring 13, is not held by the soil defining the hole, the only resistance to upward displacement is that effected by the soil engagement with the ring 13 and the inclined outer face of ring 13 facilitates the withdrawal.

  • edge 22 leading, the hole formed by the maximum diameter d4 of the leading end 22 region has a diameter greater than the diameter dl whereupon, when the member 21 is being withdrawn from the hole, the resistance of the earth to withdrawal is substantially limited to the engagement of said soil with the enlarged diameter d4.

  • the leading end 32 of diameter d4 forms a hole of greater diameter than the diameter dl and soil entering the member 31 is compressed to the bore diameter d3 to define a compressed and retained core within the diameter d2.

  • the member 42 is rigidly attached to a handle 43 by a bracket 44, which retains the axis of handle 43 is parallel to, but spaced from, the axes of members 41 and 42.
  • a footplate 45 is secured on the top of member 42 (as viewed in Figs. 4 and 5).
  • the leading end of the member 41 is located to remove the desired core and, using the handle 43 as a guide, the user can press with one foot on the foot plate 45 to drive the element 41 into the ground, whereupon a core is forced into the member 41.
  • the tool can be withdrawn, by- the handle 43, with minimum resistance because of the diameter d4 formed on the member 41 as described hereinbefore.
  • the core of earth extracted is wit-hin the member 41.
  • the user will then find a second location for removing a core and, by repeating the operation ' defined hereinbefore, a second core is forced into the first member 41, said second core pushes the first core upwardly into the member 42 and the first core can then be removed through the aperture 42a_.
