Abstract
A fluid actuated press is defined by two interlinked box shaped members having open sides with the upper member fixed and the lower member moveable with respect to the upper member. The top wall of the moveable member is positioned between the top and bottom walls of the fixed member and the space between the top wall of the moveable member and the bottom wall of the fixed member defines an expandable fluid chamber to receive pressurized fluid. When pressurized fluid is introduced into the chamber it expands the fluid chamber driving the moveable member in an upward direction toward the top wall of the fixed member and to apply a compressive force to a work piece positioned between the upper wall of the fixed member and the top wall of the moveable member. The walls of the boxed shaped member are reinforced with parallel bars which are notched or provided with tabs at the ends thereof to interlock with the bars of the adjacent connecting wall to oppose relative outward movement.
