  • Patent number: 8708287
    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. It therefore is possible to tighten the lock bearing screw within a small torque range and only to have to align the lock bearing screw with the pitch of the outer toothing. Therefore if, for example, the outer toothing has 36 teeth, the lock bearing screw only need to be aligned within a range of maximum 10°. 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.

  • Patent number: 5586737
    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.

  • Patent number: 4970964
    Abstract: A single turnout rotary guideway switch is provided with an elongated structural frame member having guidebeam, electric rail and tire path structure on each of two sides of the switch compatible with the guidebeam, electric rail and tire path structure of the guideway. Switching is achieved by rotating a movable part of the switch 180 degrees about its longitudinal axis. One elongated beam acts as a principal structural member of the frame and provides a tire path on one of the switch sides for main line car routing by the switch. Another curved beam is secured between the one beam and another elongated beam that extends generally parallel to the one beam. The curved beam cross-supports the frame and provides a tire path on the other switch side for car turnout routing by the switch. In a crossover switching station in a dual lane guideway, a pair of the single turnout rotary switches are combined with an interface guideway section to provide for lane-crossover car routing by the switches.
