摘要： A tie plate is formed with a profile defining two parallel protrusions with bores for receiving the respective ends of two clips. The two clips engage the flange of a rail to secure the rail to the plate, and therefore, to tie disposed below the plate. Since the protrusions are made integrally with the the plate, the resulting tie plate is able to support the rail securely even in the presence of large forces and/or twisting moments on the rail resulting from a train passing over the plate.

摘要： 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 above-mentioned part of the projection to come under the above-mentioned 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.

摘要： A pad for interposition between the bottom of a railway rail and a rail foundation upon which the rail stands is a single piece of elastomeric material in the form of a substantially rectangular sheet with substantially rectangular cut-outs at the center of two opposite sides and chamfering of at least the upper major face at the other two opposite sides. In a rail and fastening assembly projections which extend upwardly from the rail foundation, and are engaged by means holding the rail down, lie partly in the cut-outs and impede movement of the pad along the rail.

摘要： A rail clip is made by bending a metal bar so that one end of the bar is one end of a straight portion of the clip, further portions of the clip lead to a portion which crosses the axis of said straight portion near said one end and the other end of the bar appears to be substantially perpendicular to said straight portion. The clip can bear on a fish plate at a joint between two rails.
