Abstract
A railroad car having an improved draft gear assembly including a center sill structure terminating at one end in a draft center sill section having a yoke mounted therewith. The yoke includes first and second yoke members extending longitudinally. An interlocking coupler member including a head portion and a shank portion is mounted with the yoke. A connector assembly holds the interlocking coupler member in position in the yoke. The interlocking coupler member includes a rear butt portion positioned internally of the connector assembly for engaging a follower block mounted substantially between the first and second yoke members. A resilient member is mounted between the follower block assembly and the end of the yoke. The follower block assembly includes a central section located between the yoke members and further includes first and second guide portions which are joined to a central follower block section and extend outwardly to hold the follower block in position in spite of the application of external forces. A yoke positioner assembly is mounted with the draft sill section to maintain the yoke in a substantially longitudinal position in spite of the application of stresses through the interlocking coupler member and yoke.
