ABSTRACT:
An apparatus for coupling vehicles in a train of such vehicles including first and second coupler plates pivotally interconnected by a coupler pin for relative movement about an upright axis and having brake means frictionally retarding relative rotation between the coupler plates and a cam type latch means mounted on one plate and engageable in a depression in the other plate when the first and second plates are in a preselected angular position for releasably restraining relative movement between the coupler plates out of the preset angular position until the forces tending to cause relative angular movement substantially exceed the frictional force of the friction brake means. The coupler plates are releasably connected to the adjacent ends of two vehicles in a train by releasable hitch means and the hitch means mounts the coupler plates on the respective vehicles for pivotal movement relative thereto about a horizontal axis extending crosswise of the vehicle to accommodate minor changes in elevation between the coupled vehicles as they traverse the terrain.
