Abstract
A high speed frog including a ductile iron main pan casting having an integral straight approach runner, an integral straight exit runner, and an integral exit turnout runner, a movable runner having a pair of guide rails, an electric solenoid for rotating the movable runner so that one of said pair of guide rails is cooperatively associated with the stationary runner, diverts a sliding contact shoe to the turn-out runner, a mechanical deflector engageable for resetting the movable runner so that the other of the pair of guide rails engages the integral straight approach runner, and a renewable runner insert disposed between integral straight approach runner and the respective guide rails of the movable runner.
Claims15
A high speed frog comprising, a main pan casting having a stationary entrance runner and stationary mainline and turn-out runners, a movable runner having a pair of guide rails, an electrical operator for actuating said movable runner so that one of said pair of guide rails is cooperatively associated with the stationary entrance runner and diverts a contact shoe to the turnout runner, a mechanical deflector engageable by the contact shoe for resetting said movable runner so that the other of said pair of guide rails engages said stationary entrance runner, and a renewable runner insert disposed between said stationary entrance runner and said pair of guide rails of said movable runner.
