Abstract:
1. An apparatus for use with an elongated spacer member having two opposite ends for lifting a structure above an underlying support surface, the apparatus comprising: a base which is adapted to act against the underlying support surface during a lifting operation performed with the apparatus and which defines an upwardly-opening recess which is sized to nestingly accept one end of the two opposite ends of the elongated spacer member inserted endwise therein; a cap associated with the base defining a threaded opening whose longitudinal axis is oriented substantially normal to the underlying support surface and which defines a downwardly-opening recess which is sized to nestingly accept the other end of the two opposite ends of the elongated spacer member inserted endwise therein; and a threaded rod which is threadably received by the threaded opening and which has an extending end which extends out of the threaded opening for acting against the structure desired to be lifted with the apparatus so that by inserting one end of the two opposite ends of the elongated spacer endwise into the upwardly-opening recess of the base and inserting the other end of the two opposite ends of the elongated spacer member endwise into the downwardly-opening recess of the cap and then positioning the apparatus between the underlying support surface and the structure desired to be lifted so that the base is permitted to act against the underlying support surface and the extending end of the threaded rod is directed toward the structure desired to be lifted and subsequently rotating the threaded rod within the threaded opening so that the threaded rod moves axially therealong, the base, the spacer member, the cap and the threaded rod act between the structure to be lifted and the underlying support surface to lift the structure, and so that by selecting a spacer member of appropriate length, the apparatus can be used to lift a structure above an underlying support surface, no matter the height between the structure and the underlying support surface.
