Abstract:
1. An apparatus for cutting and collecting plugs of submerged substrate, which comprises: (a) a hollow cutting member made of a durable non-corrosive material having open top and bottom ends; (b) the bottom end of the hollow cutting member having sharpened serrated teeth to allow insertion of the hollow cutting member into the submerged substrate; (c) a seal for the top end of the hollow cutting member to create vacuum pressure inside the hollow cutting member; (d) a compressed air line mounting block with bottom and top ends, which is affixed to the exterior of the hollow cutting member; (e) a compression fitting attached to the bottom end of the mounting block; (f) a coupling attached to the top end of the mounting block; (g) a piece of tubing made of a durable non-corrosive material attached at one end to the compression fitting and attached by its exterior to the exterior of the hollow cutting member with its other end terminating above the bottom end of the hollow cutting member; (h) two handle sleeves attached to the exterior of the hollow cutting member; (i) a handle attached to the two handle sleeves, allowing for pressure to be applied by hand to insert the hollow cutting member into the submerged substrate; (j) an air gun; and (k) a section of air hose fitted with couplings at both ends such that one end will attach to the back end of the air gun and the other end will attach to the coupling on the mounting block.
