ABSTRACT:
A staple insertion apparatus is disclosed for sequentially inserting a plurality of staples through a selected material, into the ground. A housing having a top, bottom, and sides, with first and second open ends, forms a chamber therebetween. The chamber is sized to receive a plurality of staples selected from four to 12 inches in length. The staples are inserted into the chamber from the second open end. A staple advancing member biases the staples towards the first open end. A vertically disposed tubular member is secured to the housing above the first open end of the chamber. An elongated drive member is slidably disposed at least partially within the tubular member. A staple retaining member positions the forewardmost staple beneath the elongated drive member. A foot actuation member is secured to the drive member. The drive member forcibly biases the forwardmost staple through the selected material, into the ground, when the operator exerts a downward force from a standing position upon the foot actuation member. As the operator's foot is raised, a biasing member disposed within the tubular member, raises the drive member. The staple advancing member positions the next staple beneath the drive member for subsequent insertion of the next staple through the material, into the ground.
