ABSTRACT:
A mechanism for automatically shifting the tailgate latches of a vehicle-mounted dump bed as the same is being raised to insure that the tailgate is free to swing open and permit the load to begin discharging during raising of the dump bed and thus avoid a top-heavy, over-balanced condition. The mechanism also provides for the automatic latching of the tailgate during lowering of the dump bed and includes a trip arm mounted on the underside of the dump bed for rotation about a transverse, horizontal axis. The trip arm, which is operably linked with the tailgate latches for shifting the latter between open and closed positions, engages a device, mounted on the vehicle frame beneath the dump bed, that has a pair of vertically spaced trip latches, one of which is disposed to rotate the trip arm in one direction for shifting the tailgate latches to their respective open positions as the bed rises while the other trip latch is disposed to rotate the trip arm in an opposite direction as the dump bed lowers for shifting the tailgate latches to their closed positions.
