<p>"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 third, fourth and fifth parts forming an arch above the support member. A fulcrum 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 abovementioned part of the projection to come under the abovementioned part of the support member. From the lower extremity of the fifth part, i.e. the side of the arch which is further from the first part of the device, there extend sixth and seventh parts of the device, the sixth part sideways and the seventh part downwardly. 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 the sixth part of said device.</p> |
