Abstract

881,787. Boring earth. TURRIFF CONSTRUCTION CORPORATION Ltd. March 15, 1960 [Aug. 13, 1959], No. 27708/59. Class 85. A core bit houses a sheet 7 or sheath of plastic material which removably lines the interior of the bit and serves to encase the core. A sheet of transparent plastic is rolled into a tube, and is held in position within the bit by a ring 8. A ring 6 having an external tapered surface co-operating with an internal tapered surface on the part 5 of the bit serves to obtain the core within the bit.
