ABSTRACT The draft gear includes a single center friction plate and a pair of spaced apart friction wedges. Six major friction surfaces are defined, four of which are engaged upon contact with the follower, the other two being engaged after about one-half inch of travel. Three major groups of angles are defined, a first being between the friction wedges and the shoes, a second between the friction wedges and the release wedge and a third between the shoes and the spring seat. These groups of angles cooperate to insure that the draft gear will release upon removal of external force.
