发明名称 HOLDING A RAILWAY RAIL DOWN ON A SUPPORT MEMBER
摘要 <p>TITLE OF THE INVENTION "Holding a railway rail down on a support member." To hold a railway rail down on a support member, a device is employed having a first part driven into a vertical hole in the support member, a second part having a sideways projection, part of which lies vertically below a part of the support member, to one side of the bottom of the hole, and further parts forming an arch above the support member. A convex portion of the first part co-operates with the wall of the hole during the driving operation to form a pivot about which said device rocks to cause the above-mentioned part of the projection to come under the above-mentioned part of the support member. A portion of a clip is driven under the arch and presses upwardly on it, another portion of the clip bears downwardly on the flange of the rail and a third portion bears downwardly on a fixed surface which, as seen from the rail, is beyond said first portion.</p>
