Abstract
An improved lightweight knuckle is described for use in an AAR Standard E or F type railroad car coupler. The outer contouring and inner voids of the improved lightweight knuckle are radically changed without compromising the integrity or operability of the knuckle during conventional coupling and uncoupling operations with, and from, an existing AAR Standard knuckle. The nose of the improved lightweight knuckle is provided with a pair of parallel, coplanar flat surfaces between which is a projection which extend outwardly from the flat surfaces and terminates at an outer curved surface which has the same curvature as the corresponding curvature of an existing AAR Standard knuckle. Also, twin sets of reinforcement ribs are provided within the improved lightweight knuckle to strengthen the knuckle and make it more durable.
