Abstract

The steel plate fitting over the rail foot and attached to the railway sleeper consists of a base with hole in, and a screw or nut. The tightening device for the screw or nut with a hole in, the shape of which matches of a drive-piece with a hole in, the shape of which matches the outer surface of the top of the screw or nut. The electromagnetic device is in two parts which can be magnetised so that they pull the plate-base on both sides of the axle of the drive part of the tightener. The electromagnetic device is firmly joined to the drive shaft; and the supply operating it is switched on by hand. A regulator adjusts the angle at which the plate-base is laid.
