ABSTRACT:
A self driven mobile assembly including an ink agitator is supported on the ink fountain of a printing machine by a beam which is adapted to be mounted parallel to the longitudinal axis of the ink fountain so as to provide a guide track for supporting the mobile assembly for linear displacement along the ink fountain with the ink agitator projecting into the ink. The beam has a rack extending parallel to said ink fountain axis, and the mobile assembly includes a reversible motor and drive means connecting the motor both to rotate the agitator and to linearly displace the assembly along the beam by driving a pinion meshing with the rack. The beam also has an exposed bus electrically insulated from the beam and lying parallel to the rack, and the mobile assembly has a pair of members, one mounted for sliding electrical contact along the bus and the other mounted for sliding electrical contact along a portion of the beam separate from the bus for supplying electrical power to the assembly. Adjustable stops are mounted on the beam and the assembly includes motor control circuit means including micro switches mounted for movement alternately into engagement with the stops to control the operation of the motor in automatically reciprocating the assembly along the beam between the stop defined limits.
