  • Patent number: 9702091
    Abstract: 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.

  • Patent number: 4513912
    Abstract: 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.
