Abstract: A method of and apparatus for reinforcing wooden utility poles, having lower ends embedded in the ground, with elongate cage parts having grippers at their lower ends. The grippers are swingably secured to the cage parts for movement from a first position in which the grippers are in vertical alignment with the cage parts and can be driven into the earth to positions alongside the pole in which the grippers are beneath any weakened portions of the pole and can be swung to substantially grip the pole. The steps include forcing the cage portions down along the pole and then lifting the cage portions and thereby causing the pressure of the earth to swing the grippers to second position. The cage portions are secured to the pole above ground to form a unitary cage structure embracing the pole.
