RAILWAY SWITCH DEVICE FOR MOVING RAILROAD SWITCH POINTS
20210129876 · 2021-05-06 ·

A railroad switch device for moving railroad switch points. The device includes a hydraulic unit having a hydraulic manifold coupled to a hydraulic pump integrated with an electric motor via a pressure pipe, where the hydraulic manifold is also coupled to the hydraulic pump via a hydraulic oil reservoir and a return pipe, and the hydraulic manifold is coupled to a hydraulic double-rod cylinder to provide forward movement and reverse movement of a point rod. Also included is a mechanical target to automatically indicate the position of a point rod, and a plurality of spring units to produce a continuous thrust force for holding the railroad switch points closed in forward position and reverse position, wherein the plurality of spring units control the target rotation to 90 degrees.

Railroad switch position indicator
11919553 · 2024-03-05 ·

A railroad switch position indicator configured for direct attachment to switch points which guide a train from one track to another. The indicator has first and second rotating reflector signals spring biased into a neutral position signaling caution. The first rotating reflector signal rotates in response to movement of the switch points against the spring bias while the second rotating reflector signal remains in neutral position when the switch points are lined for a first direction. The second rotating reflector signal rotates in response to movement of the switch points against the spring bias while the first set of reflectors remain in neutral position when the switch points are lined for a second direction.
