  • Patent number: 5127326
    Abstract: A computer operated device for controlling an ink key (58) used to adjust the position of a fountain blade used in an ink fountain of a printing apparatus. A linear actuator (10) imparts reciprocating axial motion to a shaft (14) which in turn actuates a lever arm (34). The lever arm (34) operates an eccentrically pivoting cam (36) which transforms the axial motion from the linear actuator (10) into eccentric rotational motion. A second cam (48) reconverts the eccentric rotational motion of the first cam (36) into reciprocating axial motion and imparts that motion to the ink key (58) with a substantial reduction in distance of travel relative to that of the shaft (14) of the linear actuator (10), thereby permitting precise incremental adjustment of the position of the ink key (58).
