Abstract
Abstract A WORKBENCH OF SAW-HORSE HEIGHT HAS ITS TOP FORMED BY A PAIR OF LONGITUDINALLY EXTENDING TOP MEMBERS WHICH FORM A WORKING SURFACE AND WHICH ARE CARRIED BY TRANSVERSE SUPPORTS. ONE OF THE TOP MEMBERS IS FIXED WITH RESPECT TO THE SUPPORTS BUT THE OTHER IS HORIZONTALLY MOVABLE TOWARDS AND AWAY FROM THE FIXED TOP MEMBER TO FORM A VISE BETWEEN THE OPPOSED VERTICAL FACES OF THE TOP MEMBERS. ADJACENT EACH END THE TOP MEMBERS ARE INTERCONNECTED BY SCREW THREADED RODS WHICH ARE RESTRAINED AGAINST AXIAL MOVEMENT AT THEIR ENDS ADJACENT THE FIXED TOP MEMBERS BUT WHICH ARE RECEIVED IN NUTS CONNECTED TO THE MOVABLE TOP MEMBER. THE CONNECTION OF THE BUT TO THE MOVABLE TOP MEMBER ALLOWS INDEPENDENT OPERATION OF THE SCREW THREADED RODS TO PERMIT THE GAP BETWEEN THE VERTICAL FACES TO BE GREATER AT ONE END THAN AT THE OTHER.
