DEFINITION

Classification: 338/109

(under subclass 101) Subject matter including structure such as a screw for applying a compressive force to the pile in addition to that applied by the structure normally varying the resistance value of the pile as by compression, the first mentioned structure being adjustable as to compensate for surface wear in the piles during use.
