|20080277903||APPARATUS FOR RAISING A SPRING ARM ON A TRAILER HITCH - An apparatus for raising a spring arm of a trailer hitch. The apparatus may include a lift, such as a jack, for attaching to a tongue of a trailer. A link member may be pivotally attached to the lift. The link member may also be pivotally attached to a bracket which may be attached to the spring arm. A brace member may be attached to the link member on an end opposite the bracket. As the lift raises the link member, the link member may pivot about the brace member such that movement of the bracket may be amplified as compared to movement of the lift. Moreover, lifting of the spring arm can be easily accomplished.||11-13-2008|
