ABSTRACT:
Apparatus for effecting a push pull driving connection between a pair of vehicles disposed in tandem relation with one end of each vehicle juxtaposed relative to the other. The apparatus has a rocking beam mountable on the juxtaposed end of one vehicle for pivotal movement thereon in a horizontal plane. Bumper rollers are carried by and project from said rocking beam in axially horizontal orientation for rolling engagement with the proximal wheels of said other vehicle whereby movement of one vehicle towards the other will procure engagement of the bumper rollers with the wheels as aforesaid and upon continuation of such movement in the same general direction will transmit a pushing action to said other vehicle through the engagement of said bumper rollers with said wheels. A beam extender is at each end of said rocking beam and there is a coupling arm on each said beam extender for hooking engagement with a said proximal wheel. Each beam extender is movable between a retracted position, in which its coupling arm is disposed in engagement with a said proximal wheel, and a neutral position, in which said arm is disengaged and spaced from said wheel. A spacer interconnects said beam extenders and is operable to extend said arms into neutral position, and, thereafter, to retract them into pulling engagement with said wheels. The spacer is floating permitting lateral shifting of the beam extenders and coupling arms in unison without disengagement of said arms from said wheels while the beam extenders are in their retracted position.
