Abstract
A coupler to connect convertible rail-highway vehicles end to end to achieve train configuration to carry vertical loads of about 25,000 pounds and at the same time provide limited rolling, pitching and yaw actions between the coupled vehicles. The coupler includes a male member extending from the front of a rear vehicle and a female member in the rear sill structure of a forward vehicle receiving the male member and a releasable locking means comprised of a vertical hole through the male member, a bushing in the vertical hole, the outer surface of which bushing is spherical, a spherical seat in the rear sill structure upon which the male member rests, a vertical locking pin, the vertical axis of the hole, spherical seat and locking pin being the same, and linkage means to selectively extend the locking pin through the vertical hole in the male member to effect coupling and uncoupling.
