This Stansbury press is one of the oldest Cincinnati Type Foundry presses known to still exist, and represents the transition from wood to cast-iron as the primary construction material of printing presses.
From the Missouri Historical Society:
Wooden Handpress Used for Printing the Missouri Intelligencer and the Columbia Statesman (Dated 1818 – 1830)
Wooden handpress with cast iron bed and platen. The frame is made of heavy wooden beams painted black that hold the twin iron rails upon which the cast iron bed rides. Twin coil springs on either side (cheeks) of the frame raise the platen after the impression is taken. The frame is held together with mortice and tenon joints or rabbets and heavy bolts. The fixture on the bottom of the head indicates that the press had a Stansbury-style toggle mechanism, with two angled rods connected to a central spindle. Components are held together by square nuts and square-head bolts.
