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.

A press comprising a first member having a first and second end walls on opposite sides of said first member, and side walls on opposite sides of said first member and connected to and joining the end walls of said first member and leaving two opposite sides of said first member open, a second member moveable with respect to said first member and having an end wall positioned within said first member and shaped and positioned so that two opposite edges thereof make a sliding fit with the inside faces of the side walls of said first member, said second member having side walls connected to the end wall of said second member and shaped and arranged so that the inside faces thereof make a sliding fit with the opposite edges of said first end wall of said first member, the first end wall of said first member, said end wall of said second member and said side walls defining a chamber between the end wall of said second member and the first end wall of said first member, and means to introduce fluid under pressure into said chamber to cause said chamber to expand by causing said second member to move toward the second end wall of said first member.
