  • Apparatus for driving grade stakes
    Patent number: 5667021
    Abstract: A grade stake driver includes a frame for supporting a hammer and a grade stake under the hammer. A shuttle secured to the hammer movably mounts onto the frame to connect the hammer to the frame. A hoist secured to the shuttle mounts onto the frame to permit the raising and lowering of the hammer. A receiver mounted on the frame outputs a control signal in response to a transmitted signal. A switch mounted on the frame transforms the control signal into an on/off signal. A relay mounted on the frame connects the hammer to a power source in response to the on/off signal, thereby effecting the driving of the grade stake.
