Abstract: Disclosed is switch lock device of a railway switching actuator connected to a switching slide and a tie bar/locking slide of the actuator, the switching slide and a tie bar/locking slide being slidable one over the other to lock a blade of a railway switch in a closed position, the switch lock including an oscillating catch unit oscillating between two positions, engaging either a stationary step of a casing of the actuator or a head surface of the switching slide. The oscillating catch unit links to the end of the tie bar by a spring actuated mechanism blocking oscillation of the oscillating catch unit in an unlocked position corresponding to the engagement of the switching slide. During switching, the tie bar compresses the spring actuated mechanism, and the oscillating catch unit is free to oscillate towards a locking position, engaging the step of the casing of the actuator.

Abstract: A lock bearing for a points setting arrangement has a lock bearing screw penetrating a foot of a setting tongue and an anti-rotation ring enclosing the head of the lock bearing screw in an annular, force-fitted manner with an outer toothing and a safety plate matching the outer toothing.

The anti-rotation ring functions like an adapter for the toothing mass and contributes to the fact that no modifications need to be carried out on the remaining construction of the lock bearing, which is advantageous as regards safety and approval considerations.

Abstract: A device for operating a switch of a railway track including switch blades. The device includes a drive module, a linear operating module coupled to and driven by the drive module for generating a linear movement and at least one locking module interconnected between the linear operating module and the switch blades. The locking module transfers the linear movement from the linear operating module to the switch blades, thereby moving the switch blades across a longitudinal direction of the railway track from a first position to a second position. The at least one locking module also locks the switch blades in the first position or the second position independently of the linear operating module. A girder box forms a sleeper of the railway track for housing the drive module, the linear operating module, and the at least one locking module. The device also includes apparatus for joining the drive module, the linear operating module, and the at least one locking module.

Abstract: There is provided a cam bar of a railroad track switch machine for locking a lock bar at a particular position. Specifically, a cam bar latch interconnects a locking section, for interlocking with the lock bar, to a positioning section, for controlling the position of the locking section. For normal operations, the cam bar latch holds the two sections together. For abnormal conditions, when the cam bar is not able to lock the lock bar into position, the cam bar latch allows the two sections of the cam bar to separate and reconnect interchangeably. Thus, the positioning section may continue to move freely regardless of whether the lock bar is locked or not, and yet, control the position of the locking section when a normal condition returns. Also, the cam bar prevents an indicating means of the switch machine from indicating a "safe condition" when the two sections are separated, i.e., when an abnormal condition exists.

Abstract: In a device for locking end positions of movable switch parts, in particular, a switch lock, two relatively movable parts are displaceable into a position non-positive in respect of at least one direction of movement.

In this way it is possible to combine the advantages of reduction of the sliding friction during the re-positioning operation with a flexible securing of the end position of the currently involved adjusted position of the moveable rail or rail component (7, 7').
