摘要：
The vertical stability and longitudinal slack adjustment of a towed vehicle relative to a towing vehicle is improved by attaching to the tongue of the towed vehicle a vertically extending hydraulic piston assembly having a lateral cross arm lever member secured to the piston and spring-loaded connecting members attached between the ends of the cross member and the towing vehicle. Tension is applied to the spring-loaded connecting members by elevating the piston thereby to remove any slack between the vehicles while permitting one to turn relative to the other.
