Abstract
An ink fountain apparatus for a printing press includes an inclined member with an ink supply adjusting member which is swingable about an axis parallel with the rotational axis of an ink fountain roller for movement between a first position where ink fountain is formed and a second position where the ink fountain is not formed. Piston rods of hydraulic cylinders are connected to the inclined member via a connection mechanism to move the inclined member between the first position and the second position. Stoppers are also provided to stop the inclined member at the first position. Springs are included in the connection mechanism to press the inclined member against the stoppers. The spring force produced by the springs is smaller than the force produced by the drive means. With this structure, the work load of an operator can be reduced while enhancing the efficiency and safety of his work. Also, it is possible to prevent the inclined member from deforming even when the inclined member contacts the stoppers in different states, thereby guaranteeing smooth adjustment of the ink supply adjusting member and improving the ability of the ink fountain apparatus to supply ink.
