摘要： A railroad switch mechanism wherein the switch points of a track switch are moved between normal and release positions by a switch machine connected to the switch points by throw rod, lock rod and detector rod assemblies which are adjusted to have predetermined lengths. The lock or detector rod assemblies have couplings which enable temporary disconnection from the switch points when testing to verify whether the operation of the switch to normal and reverse positions is within an allowable range of variations with respect to the stock rails with which the track switch is associated without affecting the adjustment of the length of the assemblies and requiring long and costly readjustment after the completion of testing.

摘要： In order to provide for automatic replacement of lamp bulbs (lamps) when they fail to illuminate and to enhance the reliability of signal lamps, such as those which signal oncoming trains as they move along railway tracks, a plurality of lamps are disposed angularly spaced from each other on one side of a turntable which is rotatable under spring bias to bring the lamps successively into positions in alignment with the lens of the signal lamp. A latching mechanism having a latch member incorporated into the turntable and a detent member operated by a solenoid provides for releasable engagement of the turntable so as to enable it to move between the successive positions. The primary one of the lamps is wired directly into the signaling system while the secondary lamp or lamps is wired to be operated by a circuit responsive to the illumination of the lamp which is in alignment with the lens and which controls actuation of the solenoid and release of the turntable as well as switching of power to the secondary lamp or lamps.
