Abstract: A cut lever apparatus that automatically actuates a lock lift assembly to either lock or unlock a coupler knuckle of a freight car coupler. The apparatus includes a cylinder member having a piston disposed therein. A bracket member is attachable to the freight car coupler to support the cylinder. A linkage member is connected to the piston of the cylinder and the lock lift assembly to convert a lateral motion of the piston to a curvilinear motion of the lock lift assembly to either lock or unlock the coupler knuckle. A valve member is connected to the cylinder for communicating a pressurized fluid to the cylinder when a predetermined signal is sent to the valve and preventing pressurized fluid from entering the cylinder in an absence of the predetermined signal. Pressurized fluid in the cylinder is vented to atmosphere when the valve shuts off supply of pressurized fluid thereto.
