Abstract: A trailer hitch for attachment between a towing vehicle and a towed vehicle has a planar support member affixed to the towing vehicle and oriented substantially transversely to the towing direction. A planar slide is disposed between a pair of transversely spaced parallel vertical guides affixed to the support member and the slide is slidably retained by the guides. A tongue is affixed to, and extends from the slide in towed direction, and carries at its end a conventional hitching ball. A leaf spring is supported in vertically adjustable relation to the support member and in turn resiliently supports the tongue, and slide, at a given distance from the support member. The spring force is adjustable, as by removing or adding spring leaves.
