ABSTRACT:
Articulating devices may be used to combine railroad cars into a semi-permanent unit. Each device includes a male and female connecting member having ends attached respectively to adjacent ends of the railroad car bodies forming the unit. A pin disposed in aligned apertures formed in the outer end of each member forms a joint therebetween. To allow for vertical and horizontal movements between the members during operation of the unit, the pin aperture in the male member is larger than the pin and has a rear surface portion providing a substantial contact area with the pin. To maintain the pin aperture and pin in a controlled slack relationship, the male member is urged forward by a follower which is carried within the female member and engages an end surface of the male member. The position of the follower in turn is regulated by a wedge element which engages a pair of resilient elements carried by the follower.
