Abstract
An insulating device comprising an electrically insulating member and a metallic reinforcing member is to electrically insulate a flange-footed railway rail from a rail clip, which bears downwardly upon the upper surface of the rail flange, and from an anchorage for the clip, this anchorage being at one side of the rail flange. A first portion of the insulating member, which is to lie on the rail flange, is surmounted by an elongate portion, having a flat bottom, of the reinforcing member and a second portion of the insulating member is to be between the edge of the rail flange and the anchorage. The reinforcing member has at least one reinforcing rib extending along and upwardly from the elongate portion and it has two sideways projections which are to extend on opposite sides of the anchorage to prevent the reinforcing member moving along the rail. No part of the reinforcing member is below the plane containing the flat bottom of the elongate portion.
