摘要： A rail fastening device comprises a clip (10) having a base (11) and a nose (12) for engaging a rail flange (F). The base (11) comprises circular aperture (14) in which a circular cam (13) is rotatably mounted, the cam (13) being provided with an eccentric aperture (24) for receiving a ground anchor (25), the cam aperture (24) being radially offset from the rotational centre of the cam (13) to define a cam lobe (15). The cam (13) may comprise a ramped circumferential shoulder (18) to engage a complementary shoulder (21) inside the base aperture (14) such that any rotation of the cam (13) under the applied load of the rail causes the cam (13) to move axially of the base aperture (14) thereby tightening the engagement of the anchor (25) on the cam (13) and preventing movement of the clip (10). The degree of rotation of the cam (13) may be limited so that it can only turn in the tightening direction under load.

摘要： A holddown assembly fastens a railway rail to a transversely extending hollow sleeper formed with a vertically throughgoing hole. An upwardly projecting lateral brace element is provided on the sleeper offset from the hole, and the assembly has a body fitted between the rail and the brace element and transversely bracing the rail against the brace element. An anchor of the assembly is engaged through the hole, projects upward from the sleeper, is transversely shiftable in the hole, and bears upward on the sleeper. A spring clip is pressed by the anchor down against the rail and presses the rail down against the metal sleeper.

摘要： A universal slide-plate includes a body and a drop-in shoulder member with a plurality of retaining members that cooperate to selectively connect the universal slide-plate and a stock rail to a rail platform and/or tie. The universal slide-plate has a slide surface configured to support a moveable point rail thereon. The universal slide-plate may be selectively removed and repositioned relative to a rail platform and/or tie.

摘要： A rail clip assembly comprises a body for overlying a portion of a rail and for overlying an adjacent portion of a rail support means, the body having a first surface for abutment with a lateral face of the rail and an aperture for receiving means for securing the body to the rail support means, the aperture being elongate in a direction inclined at an acute angle to the direction of extent of the rail, and securing means including a first securing member for overlying the body and having an aperture therein for alignment with the aperture in the body and for receiving a second securing member which extends therethrough and through the elongate aperture in the body, the first securing member having a surface which in use abuts a second surface of the body in all positions of the body relative to the securing means for transmitting laterally directed forces applied by the rail to the body from the body to the first securing member, the second surface of the body extending in a plane inclined to the rail support means surface and parallel to the direction of elongation of the aperture, the second surface facing away from the first surface.

摘要： A rail clip for securing a rail to a rail support composed of two bodies, one of which overlies a portion of the rail and the other of which overlies the rail support and has a lateral face which abuts the rail. Both bodies have registering apertures to receive a connecting member fixed to the support, the aperture in the second body being elongated so as to enable the bodies to assume different relative positions when assembled on the connecting member, the contacting faces of the bodies being shaped to provide positive engagement between them when assembled.

摘要： A filament is made by curling a ribbon of suitable material transversely of its elongation, and drawing the curled ribbon. The resulting filament has a cross section resembling a tight spiral and may be hollow or solid. Thermoplastics may be used as the ribbon material. An apparatus and a method are disclosed for making this filament. This invention relates to filaments and methods and apparatus for making them.
