  • Patent number: 4207966
    Abstract: A multipurpose staging horse is disclosed comprising two coplanar legs converging upwardly towards each other and rigidly secured near their upper ends by a horizontal bar member; the upper ends of the legs project vertically upward and form with the bar member a stirrup in which may be secured a beam of wood or the like; the stirrup includes in one of its arms a wing screw projecting transversely inward to secure said beam of wood; a transverse bar interconnects the legs near their lower end to maintain the same at their proper spacing and holds a pivotable brace projecting upwardly and away from the legs and also having a stirrup at its upper end aligned with the first named stirrup to receive the same beam of wood. The brace is slightly offset laterally from the center line of the two aligned stirrups so that two staging horses may be used as an oppositely positioned pair wherein their respective braces cross each other without interference.
