Abstract A TABLE TOP IS SUPPORTED IN CANTILEVER FASHION FROM TWO SPACED APART VERTICALLY MOVABLE POSTS WHICH ARE GUIDED IN UPRIGHT COLUMNS. A CROSS GUIDE EXTENDS BETWEEN THE COLUMNS AND IT SUPPORTS A CARRIAGE FOR BIDIRECTIONAL LONGITUDINAL MOVEMENTS. OPPOSITE ENDS OF A CHAIN ENGAGE THE POSTS AND THE CHAIN RUNS OVER GUIDE SPROCKETS ONE OF WHICH IS CARRIED BY THE CARRIAGE. THE CARRIAGE SPROCKET IS SELECTIVELY LOCKABLE AND RELEASEABLE SO THAT WHEN THE CARRIAGE IS TRANSLATED BY SUITABLE POWER MEANS THE TABLE ELEVATES. RELEASE OF THE CARRIAGE SPROCKET PERMITS THE TABLE TO BE INCLINED LONGITUDINALLY IN EITHER DIRECTION BY PRESSING OR LIFTING ON EITHER END THEREOF.
