Abstract
A spring retention device particularly well suited to use on railcars. The spring retention device has first and second fingers that oppose each other at inclined interior surfaces to define an opening. The interior surfaces overlap and are inclined relative to opposed substantially parallel and planar surfaces with which the first finger is substantially aligned between aside from its terminal end which is bent so the first finger extends outwardly from the first planar surface. The opening terminates in an enlarged portion that has an interior surface defining the perimeter of the enlarged portion. The interior surface of the enlarged portion is substantially perpendicular to the planar surfaces. Springs having eyes that have their wire bent in substantially the same plane may be inserted through the opening, then when turned to align with the enlarged portion, the spring contained therein will be prevented from backing out of the opening.
