A combination caster and fixed support that supports an article either for rolling motion on a dual wheel assembly or alternatively supports the article on a floor engaging foot that raises the caster wheels from the floor. A central horn, having a vertical swivelling pintle, carries wheels on the opposite sides thereof supported on a common axle that permits the wheels to go up and down a limited distance relative to the horn to compensate for uneven floors. A threaded pad vertical support rod is received centrally in the horn between the wheels and carries a universally mounted channel-shaped pad at its lower end that selectively engages the floor as the threaded rod is lowered to raise the caster wheels off the floor. In the raised position of the foot the pad is locked in a tilted position between abutments on the lower end of the support rod and a lower surface on the horn so that the pad may easily pass over inclined floor surfaces.

A combined dual wheel caster and support pad assembly comprising; horn means, a wheel supported on each side of the horn means for rotation, a pad support mounted for vertical adjusting movement in the horn means and having a lower thrust surface, a pad mounted on the pad support for pivotal movement, said pad support being movable downwardly to engage the thrust surface with the pad to lower the pad into engagement with the floor and raise the wheels from the floor, and means for locking the pad in an upward tilting position so that the pad does not interfere with obstacles when the wheels operatively engage the floor.
