ABSTRACT:
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.
