Abstract (en)
[origin: US4513663A] A mechanism for axially reciprocating at least one of the distributing rollers of a printing press. A rocker having an elongated slot therein is mounted on a first pivot and oscillated thereabout by means of a link eccentrically connected to the press drive shaft. An oscillating lever is pivotally connected to the press frame for movement about a second pivot and includes a sliding block captively held in the elongated slot of the rocker. The oscillating lever is operatively connected to at least one of the distributing rollers so as to axially reciprocate the roller in response to the oscillation of the lever. The location of the first pivot is adjustable with respect to the press frame so as to change the orientation of the elongated slot in the rocker and, thus, vary the magnitude of travel of the oscillating lever which reciprocates the distributing roller. For such purpose, the first pivot is secured in one arm of a two-armed lever, the lever being pivotally connected to the frame. The second arm of the lever is secured to a traveling nut which is threaded on a shaft mounted for rotational movement with respect to the frame. Either a manually turnable knob or an electric motor is connected to the shaft so as to rotate the same, resulting in a rotation of the two-armed lever about its pivot to change the position of the first pivot held in the first arm of the lever.
