TIMED THRUST UNCOUPLING MECHANISM FOR PASSENGER TRANSIT TYPE RAILWAY CARS

摘要

An improved coupler control circuit board which can be positioned in an environmentally protected location for controlling an uncoupling operation of a mechanical type coupler mechanism utilized to connect adjacently disposed ends of a pair of passenger transit type railway cars. Such coupler control circuit board includes a power supply device connected to receive a predetermined input voltage. The power supply device reduces such predetermined input voltage received therein to a suitable predetermined output voltage. A timer/sequencer device is connected to receive as inputs thereto both such predetermined output voltage from such power supply device and an uncoupling command signal from a momentary input command for providing a pair of output signals. A first relay driver is connected to receive a first one of such pair of output signals from such timer/sequencer means for providing an uncoupling output signal, and a second relay driver is connected to receive a second one of such pair of output signals from such timer/sequencer means for providing a coupling output signal.
