Abstract
An enclosed axle, inclined wheel caster including a generally disc like pivot support, or body frame member, which may be flat or dished, carrying an axle and a supporting wheel member rotatably mounted on the axle, both of such members being made from stampings, moulding or forgings and a cover formed of opposed saucers, or cupped members, or combinations of these forms, attached to each of the members to give the swivelable caster a generally enclosed form. As an alternative form of the invention, one or both the body frame member and the supporting wheel member may be made as castings, or mouldings each having light weight opposed saucers, cupped, bulged or non-bulged truncated cone forms attached thereto to provide a covering for the body frame and axle of the completed caster.
