ABSTRACT:
A spring assembly is carried by a mounting casting. The mounting casting includes a receptacle which is adapted to mount to a horizontal frame member by means of a vertical bolt which, when tightened, adjusts the elevation of the spring assembly by rotating the mounting casting about the frame member due to a shim effect achieved by the slight off-parallel alignment of the receptacle and the axes of the springs. This raises the spring assembly to take its weight off the draw bar and makes it easier to telescope the draw bar. A spring casting includes upper dogs for mounting an actuating lever which is rotatable between a latching and an unlatched position by vertical motion. A latch member on the draw bar is locked between the spring casting and the lever, but is released when the lever is lowered to permit the draw bar to be extended to the rear for alignment with a trailer hitch. Other improvements permit the use of coil springs without grinding the ends flat.
