The door is easily, quickly and tightly locked by means REX EMERGENCY KNUCKLE It has become common practice on American railroads tocarry in cabooses so-called emergency knuckles. These de-vices can be applied in place of any standard knuckle incase of breakage, and are stronger than chains and easier toapply. The National Car Ecjuipment Company, Chicago,is now manufacturing a new device of this type which isknown as the Rex emergency knuckle. When applied it isheld in place by the knuckle pin and by a rib extending. Emergency Knuci<le That Can Be Appiied V^ithoutRemoving Knucl<le Loci< over the side wall of the coupler. This makes it unnecessaryto remove the locking device from the coupler before applyingthe emergency knuckle. The Rex emergency knuckle hasthe further advantages of being light and easy to apply, andits use does not increase the distance between cars. It hasalready been adopted by several important railroad systems.
