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.
Claims14
A caster comprised of two basic parts including a substantially flat body frame and a separate wheel rotatable relative to the body frame, said body frame being fabricated from a metal stamping and having a vertical swivel tube socket separately formed and mounted thereon, means securing said swivel socket to the body frame, a canted axle mounted on the body frame, said wheel being fabricated from a metal stamping and rotatable on said axle, a pair of enclosing covers secured respectively to said body frame and to said wheel, said swivel tube socket extending at an angle to the plane of said body frame and at least a portion of said socket extends through the body frame, and a cut-out in the body frame for the passage of said socket.
In a caster assembly comprised of two basic parts including a body frame and a wheel rotatably mounted relative to an axle carried by the body frame, said body frame having a vertical swivel tube socket formed as an integral part of the body frame, a thin gauge sheet metal shell enclosing one side of said body frame and said swivel tube socket, said metal shell extending over the peripheral edge of the body frame and crimped over such edge to secure the shell on the body frame, said wheel having a tread portion overlying said crimped over metal shell, and a thin gauge sheet metal shell enclosing the open side of the wheel and secured to a tread portion, said caster assembly being characterized by the fact that said wheel is comprised of two basic parts including a first member having an annular outer rim and an annular inner hub connected by an intermediate web, a second member having an annular outer hub in axial alignment with the inner hub and an integral web disposed in face-to-face engagement with said intermediate web and secured thereto, and a bearing sleeve in said aligned hubs between the wheel structure and said axle.
