Abstract: The invention relates to a mechanism for selectively converting a continuous rotary movement in apparatus such as a high-speed-printing machine to a phase-related single pivoting movement of a control lever, with that single control movement following by an immediate reset to the initial position regardless of the time of activation of the mechanism. An entrainment lever supported on a supporting pin is coupled by means such as an excentric drive to the continuous rotary movement of the machine to generate a continuous pitching movement. A control lever is mounted for rotation on the same support pin and mounts a bistable mechanism (tensioning lever, pawl 3, tensioning spring 21) which in its first stable condition allows the entrainment lever to oscillate freely and which can assume its second stable condition when entrainment lever is in a dead center position, causing an engagement surface to be offered to the entrainment lever with the range of its pivoting movement. Control lever is spring-biased towards entrainment lever by return spring, and the control movement of control lever causes said bistable mechanism to be reset to its first stable condition by means of a reset lever.

Abstract: Plate changing apparatus for use with offset printing machines, including a plate stacking table, plate individualizing means for sequentially withdrawing only the lowermost plate from the stacking table, and plate transporting and guiding means to guide the freshly withdrawn plate to a form cylinder of the printing machine after having passed through a fixing bath. The apparatus includes means to pass the separated plate through a fixing bath prior to its deposit on the form cylinder and a depository for used plates removed from the form cylinder. The novelty resides in the individualizing means including a rotatable vacuum roll disposed adjacent a partly open bottom surface of the plate stacking table or container or tray holding the plates so that it can engage the lowermost plate. The vacuum roll has its shaft mounted in parallel with the leading edge of the plate stack for linear displacement in parallel with the bottom stack surface. A fixing bath container is disposed directly below the plate stack and the individualizing means and adjacent the form cylinder. This arrangement results in a particularly compact construction while enabling the plates to be handled carefully.
