摘要： In a spring bar trailer hitch assembly having spring bars each of which are connected at one end to the tractive vehicle to extend on one side of the trailer and the opposite distal end connected to the trailer so as to be free to move longitudinally relative to the trailer, the improvement comprising the connection of each of the spring bars in planes horizontally offset from the plane in which the hitch ball is located so that upon pivotal movement of the tractive vehicle and trailer relative to each other, as in fishtailing, will meet with significant initial resistance by both spring bars, but as the trailer moves further from the centerline of the tow car as in rounding a curve, the longitudinal movement of one of the spring bars relative to the trailer will be greater than such movement of the other spring bar thereby effecting a greater force on the side of the trailer on the outside of the curve than the force exerted on the side of the trailer located on the inside of the turn.

摘要： The spring bar assembly for trailer hitches provides for each articulating spring bar, located adjacent opposite sides of a trailer A frame, dual suspension members interconnecting the free end portion of the spring bar with the A frame in such a manner that the opposite ends of each of the suspension members are connected at points lying in spaced, imaginary, vertical planes to thereby provide a bending lift on the spring bar of relatively great amount in relation to the amount of relative horizontal movement between the spring bar and A frame.
