ABSTRACT:
A ball and socket joint for supporting the body of a dumper truck has an upright stem, designed to be fixed to the body of the truck, with a ball head positioned in a socket on the chassis of the truck so that the stem is upright when the body is horizontal. The socket has two or three cutouts in its upper edge for receiving the stem of the ball when the body of the truck is in any one of the positions of dumping. On the side of the socket having no such cutout, the socket has a keeper nosepiece extending outwardly therefrom which, in turn, pivotally supports a locking lever which has a spring for forcing it against the ball within the socket to lock it in position. The springs are generally upright and have their top ends joined with a top end of the locking lever and their lower ends joined with a part of the socket so that the locking part is levered about a turnpin of the pivotal support offset from a straight line joining the ends of the springs. The locking part is made to be weighted on one-side with respect to the turnpin supporting it so that, even without the effect of the springs, it would be kept lockingly rested against the ball of its own weight.
