ABSTRACT:
An uncoupling device for rotary dump cars in which the car couplers are of the bottom operating type, wherein at each end of the car the uncoupling mechanism is made of the same type, and comprising both the rotary and non-rotary couplers of the car being equipped with paddle type lock lifters having a pivotal operating stroke that unlocks and opens the coupler knuckle, and a bail type actuator therefor, wherein the actuator comprises a bail member mounted on the end of the car to receive the center sill and swing about a horizontal axis extending crosswise of the car and located at approximately the level of the top of the car center sill and adjacent its striker. The bail member has a striker section that underlies the center sill and is equipped with a paddle striker that is arced to accommodate coupler side swing. The uncoupling device includes a handle structure journaled on the end of the car to have a cranking axis that is adjacent to but below the level of the car center line of draft and connected to the bail member through a lost motion, camming type connection to swing same to bring the bail member striker into striking engagement with the paddle, to thereby move the paddle through its full operating stroke to unlock and open the coupler knuckle. The bail member is spring-biased to a retracted position spaced from the paddle and disposed under the center sill striker.
