ABSTRACT:
A new tool for cleaning out unwanted debris from the bottom of trenches of the type having at the top portion of its two handles (2) rubber sheathing (1) for better gripping. The handles (2) of the tool extend the entire length of the tool. At the bottom of the handles (2) are attached two scooper trays (4). The handles (2) are attached to each other by way of a fulcrum provided by a bolt (3) that passes through each handle (2) and secured by a nut and washers (3). The tool functions by way of an operator pulling outward on the rubber sheathed (1) portion of the handles (2) to cause an opening action at the bottom of the tool whereas the trays (4) move outward from each other. Once the trays (4) are positioned around the debris to be removed, the operator moves the rubber sheathed (1) portion of the handles (2) back toward each other causing the same action on the opposite end with the result being the trays (4) moving inward toward each other and slicing under the debris to be removed. The debris is now resting on the trays (4) and is ready for removal. As the tool is lifted from the trench, acceptable (regulator) debris falls through the apertures (6) in the trays (4) and remains in the trench. Unwanted (non-regulatory) debris is then lifted out and removed from the trench.
