Printing press drive

Abstract

Abstract A PRINTING PRESS INCLUDES A PAIR OF CYLINDERS FOR SIMULTANEOUSLY PRINTING MATERIAL. THE CYLINDERS HAVE SHAFT ENDS THEREON FOR SUPPORT THEREOF. THE PRESS ALSO INCLUDES A DRIVE MEANS FOR TRANSMITTING TORQUE FROM A SOURCE OF POWER TO ONE OF THE CYLINDERS. THE DRIVE MEANS INCLUDES A WORM DRIVINGLY CONNECTED TO THE SOURCE OF POWER WHICH TRANSMITS TORQUE TO ANOTHER GEAR MESHING THEREWITH. THE DRIVE MEANS ALSO INCLUDES A CLUTCH WHICH HAS A BODY ROTATABLY MOUNTED ABOUT ONE OF THE SHAFT ENDS OF THE CYLINDERS AND HAS A CIRCUMFERENTIAL SURFACE PORTION THEREABOUT. THE BODY HAS A RADIAL FLANGE EXTENDING FROM THE CIRCUMFERENTIAL SURFACE PORTION. THE OTHER GEAR, WHICH MESHES WITH THE WORM, HAS CENTRALLY LOCATED APERTURE THEREIN AND RECEIVES THE CIRCUMFERENTIAL SURFACE PORTION OF THE BODY. THE OTHER GEAR IS MOUNTED ON THE BODY SUCH THAT ITS ROTATIONAL AXIS IS COEXTENSIVE WITH THE ROTATIONAL AXIS OF THE SHAFT END UPON WHICH THE CLUTCH BODY IS MOUNTED. THE OTHER GEAR HAS FIRST AND SECOND SIDES ADJACENT TO THE CENTRALLY LOCATED APERTURE. THE OTHER GEAR IS POSITIONED ON THE BODY SUCH THAT THE FIRST SIDE IS ADJACENT TO THE RADIAL FLANGE AND THE SECOND SIDE IS ADJACENT TO A PORTION OF A FIRST MEMBER SO THAT THE FLANGE ENGAGES THE FIRST SIDE AND THE FIRST MEMBER ENGAGES THE SECOND SIDE OF THE OTHER GEAR. WHEN A CLAMPING FORCE IS PROVIDED ON THE OTHER GEAR BETWEEN THE RADIAL FLANGE OF THE BODY AND THE FIRST MEMBER, TORQUE IS TRANSMITTED FROM THE OTHER GEAR TO THE BODY AND FIRST MEMBER. A SECOND MEMBER IS SECURED TO THE SHAFT END OF THE CYLINDER AND A THIRD MEMBER IS NONROTATABLY SECURED TO THE BODY AND FIRST MEMBER. THE THIRD MEMBER IS MOVABLE WITH RESPECT THERETO BETWEEN A FIRST OR TORQUE TRANSMITTING POSITION IN WHICH A PORTION OF THE PIN MEMBER IS ENGAGED WITH THE THIRD MEMBER AND A SECOND OR DISENGAGED POSITION IN WHICH A PORTION OF THE PIN MEMBER IS NO LONGER ENGAGED WITH THE THIRD MEMBER.
