ABSTRACT OF THE DISCLOSURE Removing the draft key from a so-called E-type railway car coupler can be a difficult job. A relatively simple tool for removing a key of the type including a flanged head includes a pair of parallel hydraulic cylinders, a yoke interconnecting one end of the cylinders, piston rods extending out of the other end of the cylinders, a sleeve in the yoke parallel to the cylinders, an elongated shaft for removable mounting in the sleeve, a latch for retaining the shaft in the sleeve, and a socket in the outer free end of the shaft for receiving the head of the key, whereby with the shaft in the sleeve and connected to a key, extension of the piston rods against the coupler pocket pushes the cylinders, and consequently the sleeve and shaft outwardly to pull the key from the coupler.
