DEFINITION

Classification: 338/106

(under subclass 103) Subject matter including structure such as a screw for applying a compressive force on the pile in addition to that applied by the electromagnetic operator, or on the spring, if any, which exerts a pressure releasing force on the pile in opposition to that exerted by the electromagnetic operator, the structure being adjustable as to compensate for surface wear in the piles during use.
