Abstract: A trailer hitch having a bar with a hitch socket at its forward end is releasibly, pivotally and longitudinally mounted on the trailer frame such that it can be automatically latched in place merely by forward movement of the towing vehicle. A pivot is provided which includes a first member movable longitudinally of the trailer frame with a pivotal second member pivotally mounted on the first member. Spring biased pins automatically lock the slidable and pivoting members rigidly to the trailer frame when in latching positions and provided back-up safety protection against surge overloads.
