Railroad switch signaling device
Abstract:
An apparatus for indicating the position of a point detector bar having an outer surface and linked to a moveable point associated with a fixed rail utilizing a probe. The probe is moveable to contact and ride on the outer surface of the point detector bar. A housing is connected to the probe and is moveable toward point detector bar also. A leg is positioned relative to the housing to form a unit. The leg is moveable within and relative to the housing when the probe contacts a certain portion of the outer surface of the point detector bar. A driver is linked to the leg and the housing unit and moves the housing and connected probe toward the point detector bar. A signal generator alerts the relative movement between the housing and leg within the housing and the probe contacts a certain portion of the outer surface of the point detector bar which may take the form of an enlarged diameter area.
