Abstract
A rectilinear positioning mechanism for precisely controlling the rectilinear position of an output member. The rectilinear positioning mechanism of this invention includes a relatively thin beam which is flexible particularly along its longitudinal length. The flexible beam is fixed against movement at one end while the other end is free to move in the longitudinal direction. There is an input mechanism located between the ends of the flexible beam for deflecting the center of the flexible beam in a controlled, precise manner to thereby change the position of the free end of the beam. The mechanism has utility as a positioning means generally and for positioning the ends of segments of a metering blade with respect to the ink fountain roller in an ink fountain assembly.
