Abstract
A method for extracting a connector secured in a rail comprising a body member having a chamber for receiving the body of the connector to be extracted and an actuator coupled to the body member and including a bolt which is externally operated for applying force to a shoulder portion of the connector and counter bearing force to the rail to axially extract the connector from the rail.
Claims4
A method of removing from a rail a connector having a projecting pin secured in the rail and connected to a body by a shoulder, said method comprising
- positioning an extractor device adjacent to the web of a rail from which a connector is to be removed, the extractor device being disposed such that a body of the extractor device is horizontal and a receiving chamber in the body faces longitudinally of the rail and receives the body of the connector, the receiving chamber having a flared opening through which the body of the connector is guidably introduced into the chamber to center the body in the chamber while the projecting pin of the connector rides in a slot in the body of the extractor device until the projecting pin reaches the end of the slot and the shoulder of the connector bears on a supporting surface of the extractor device,
- guidably supporting a pair of pins of an actuator in bores provided in the body of the extractor device such that when the body of the connector is received in the chamber, the pins face the wed of the rail,
- moving the actuator relative to the body of the extractor device until the pins bear against the web of the rail and,
- turning a bolt threaded into the extractor device and bearing against the actuator to apply an extractor force on said shoulder and a counterbearing force on the web by the pins such that the connector is pulled out of the rail.
