  • Patent number: 4211427
    Abstract: A weight distribution trailer hitch which has a pair of spring rods pivotally connected at their forward ends on vertical-axis pivot means adjacent the hitch ball and at their rear ends in a tension relation to the trailer tongue. Cooperating means on the spring rods and the pivot means prevent the axial displacement of the forward end portions of the spring rods from the pivot means and includes a retaining clip mounted on the pivot means. The retaining clip has a leg that is biased radially inwardly into the pivot means and into a groove formed in the spring rod. Insertion of the end portion into the pivot means forces the leg outwardly which then is urged into the groove when they are aligned.
