Patent ID: 7314098

Claim:
A hand-held vibratory apparatus for driving and extracting a stake, the apparatus comprising: a motor having a shaft; a vibrational energy generating means coupled to the shaft and powered by the motor; a stake-holding means connected to the vibrational energy generating means such that vibrational energy generated by the vibrational energy generating means is transferred to a stake through the stake-holding means, wherein the stake-holding means further comprises a gripping device enclosed within a housing, the housing having an opening at bottom end for the insertion of a stake, the gripping device comprising a pair of opposed planar members coupled to the housing, the planar members capable of being positioned to hold a stake, wherein at least one planar member is coupled to the housing via springs, and wherein the positioning of at least one planar member is controlled by a wire such that as the wire is pulled the planar member is pulled against the springs thereby compressing the springs; and a frame assembly from which the motor, the vibrational energy generating means, and the stake-holding means are suspended, the frame assembly having a pair of handles for holding and operating the hand-held vibratory apparatus.
