Patent ID: RE41126

Claim:
A trailer comprising: an articulated frame having at least a pair of transversely opposed wheels rotatable about an axis of rotation, said articulated frame including a tilt frame pivotable about a tilt pivot axis and a draft tongue pivotally connected to said tilt frame for pivotal movement about an articulation axis located forwardly of said tilt pivot axis , said draft tongue being adapted for connection to a prime mover ; and a bed frame supported on said articulated frame for selective pivotal movement relative to said articulated frame about a dump pivot axis oriented rearwardly of said tilt pivot axis, said bed frame being selectively movable with said tilt frame about said tilt pivot axis , said bed frame being connected to said articulated frame by a connection apparatus positioned forwardly of said tilt pivot axis to restrict pivotal movement of said bed frame relative to said tilt frame, said articulated frame including a locking device selectively coupling said tilt frame to said draft tongue to restrict pivotal movement of said tongue relative to said tilt frame about said articulation axis, said locking device being operable to cause said bed frame to pivot about the selected one of said dump pivot axis and said tilt pivot axis .
