Abstract
The legs of a swivel caster assembly horn are mounted to a pair of horizontally-spaced beam plates which are pivoted to the legs ahead of the swivel axis. The caster wheel is mounted on an axle behind the swivel axis. A pair of urethane springs is mounted to the horn legs ahead of the pivot axis. A bolt across the front ends of the beams receives collars, each collar having a threaded transverse aperture which is screwed onto threads on the lower ends of bolts whose upper ends have heads with flanges which bear downward on a spring cap plate bearing downward on the tops of the springs, whereby the load on the caster horn is applied by lever action to the springs which are pre-loaded by the collars screwed onto the bolts.
