Abstract
Rotary printing presses of the type embodying rotatably driven series of inking cylinder, plate cylinder and impression cylinder components. Particularly, a mechanism for 'bumping' the impression cylinder shaft with respect to the plate cylinder for press adjustment or repair and web adjustment without dismantling of the press. The 'bumping' mechanism includes eccentric bushing plates supporting the impression cylinder shaft at either end and a pivotally mounted bell crank with a follower strut pivotally secured to the bushing plate. As the bell crank is pivoted, the impression cylinder shaft is 'bumped' or displaced with respect to the plate cylinder.
