Abstract
A fluid pressure roller jack consisting of a flexible inflatable and collapsible fluid-tight bag which is formed with inherent fold lines such that the bag is invariably folded along the fold lines adapted to be kept folded while it is being collapsed. In a collapsed position the roller jack is rectangular in configuration in a plane having cut off its corners, while in a fully inflated position the roller jack is a sausage-like body in the form of a cylinder having hemispherical ends. The several fluid pressure roller jacks serve to lift a heavy article as jacks by an inflation from collapsed position to inflated position and to transport the heavy article supported on the roller jacks as rollers.
