ABSTRACT:
A fifth wheel is illustrated having laterally extending wedge-shaped integral continuations of the fifth wheel for engaging a stop carried beneath the bottom surface of the trailer to limit angular movement between the tractor and trailer. Grease fittings and passageways are provided for greasing the upper surfaces of the wedge-shaped projections so as to facilitate their support of the trailer during turning. The connecting and operating of the tractor-trailer rig is facilitated by the application of grease to these upper surfaces which due to their extreme lateral disposition, engage the lower surface of the trailer magnifying the need for the application of grease.
