Abstract

See full text

An apparatus which is positionable between a structure to be lifted and an underlying support surface for lifting the structure utilizes a bottom plate and a cap between which a spacer member, such as a piece of tubing, is positionable and a threaded rod which is threadably received by an internally-threaded opening in the cap. By rotating the threaded rod within the cap, the threaded rod moves lengthwise relative to the cap. Therefore, by positioning the apparatus between a structure to be lifted and an underlying support surface and then rotating the threaded rod within the cap, the bottom plate and the threaded rod act between the structure to be lifted and the underlying support surface to lift the structure.
