Abstract
An adjustable rail anchorage arrangement comprises: a support surface (24) for supporting a rail (26). A platform base (4) is fast with this support surface and a boss (9) is upstanding from the platform base. A passageway in the boss captively receives a threaded bolt and nut assembly (1/2/23) having a shaft (2). A rail clip (15) has a hole (17) that encompasses the boss and the shaft and there is a cam (18) having a hole (20) whereby the cam is fitted over the boss and the shaft. A cam surface of the cam engages the rail clip whereby rotation of the cam causes lateral movement of the rail clip, whereafter the cam can be clamped in position by the bolt and nut assembly.

An adjustable rail anchorage arrangement comprising:
- a support surface for supporting a rail;
- a platform base fast with said support surface;
- a boss upstanding from said platform base;
- a passageway in said boss;
- a threaded bolt and nut assembly captively received in said passageway;
- a shaft of said bolt and nut assembly;
- a rail clip;
- a hole in said rail clip that encompasses said boss and said shaft;
- a cam;
- a hole in said cam, said hole receiving both said boss and said shaft and preventing movement of said shaft relative to said boss but allowing rotation of said cam about said boss;
- and
- a cam surface of said cam that engages said rail clip whereby rotation of the cam causes lateral movement of the rail clip, the bolt and nut assembly serving for clamping the cam in the position to which it is rotated.
An adjustable rail anchorage arrangement comprising:
- a support surface for supporting a rail;
- a platform base fast with said support surface;
- a boss upstanding from said platform base;
- a passageway in said boss;
- a threaded bolt and nut assembly captively received in said passageway;
- a shaft of said bolt and nut assembly;
- a rail clip;
- a hole in said rail clip that encompasses said boss and said shaft;
- a cam;
- a hole in said cam whereby the cam is fitted over said boss and said shaft;
- and
- a cam surface of said cam that engages said rail clip whereby rotation of the cam causes lateral movement of the rail clip, the bolt and nut assembly serving for clamping the cam in the position to which it is rotated, there being a gap between the lower surface of the cam and the upper surface of the platform base.
An adjustable rail anchorage arrangement comprising:
- a support surface for supporting a rail;
- a platform base fast with said support surface;
- a boss upstanding from said platform base;
- a passageway in said boss;
- a threaded bolt and nut assembly captively received in said passageway;
- a shift of said bolt and nut assembly;
- a rail clip;
- a hole in said rail clip that encompasses said boss and said shaft;
- a cam;
- a hole in said cam whereby the cam is fitted over said boss and said shaft;
- and
- a cam surface of said cam that engages said rail clip whereby rotation of the cam causes lateral movement of the rail clip, the bolt and nut assembly serving for clamping the cam in the position to which it is rotated, there being a bearing zone between said cam and said boss, and said rail clip having an abutting surface that contacts the vertical edge of the rail toe of the rail that is being anchored said vertical edge of said rail toe being below the lowest part of said bearing zone of said cam on said boss.
An adjustable rail anchorage arrangement comprising:
- a support surface for supporting a rail;
- a platform base fast with said support surface;
- a boss upstanding from said platform base;
- a passageway in said boss;
- a threaded bolt and nut assembly captively received in said passageway;
- a shaft of said bolt and nut assembly;
- a rail clip;
- a hole in said rail clip that encompasses said boss and said shaft;
- a cam;
- a hole in said cam whereby the cam is fitted over said boss and said shaft;
- and
- a cam surface of said cam that engages said rail clip whereby rotation of the cam causes lateral movement of the rail clip, the bolt and nut assembly serving for clamping the cam in the position to which it is rotated, said passageway being eccentrically positioned in relation to the center of said boss and said hole in said cam being eccentrically positioned in relation to said cam surface.
