  • Patent number: 4907507
    Abstract: An offset printing press having an operating lever mechanism which is capable of controlling sequential printing operations by manipulating a single operating lever. The offset printing press includes an inking roller system and a dampening roller system. The inking roller system is supported to a first pair of frames, while the dampening roller system is supported to a second pair of frames pivotable relative to the first pair of frames. The operation lever provides pivotal motion of the second pair of frames for selectively applying water to a plate cylinder from the dampening roller system. Further, rollers in the dampening roller system are movable toward and away from each other.

  • Patent number: 4901944
    Abstract: A fishing reel includes a drag adjustment mechanism comprising a plurality of drag washers in the form of friction plates mounted on a master gear shaft. The drag washers are urged into contact with a master gear that is selectively connectable to a spool shaft so that the master gear can rotate together with the master gear shaft and can slip relative thereto. A drag adjustment member is mounted on the master gear shaft and is operable to move the master gear shaft to urge the drag washers toward the master gear by pushing a ball bearing and a drag spring washer to thereby cause a drag adjustment. A drag preset member is mounted on the master gear shaft and is moveable along the master gear shaft to urge the drag washers toward the master gear by pushing the drag adjustment member, the ball bearing and the drag spring washer to thereby cause a drag adjustment.

  • Patent number: 4898094
    Abstract: An apparatus and method for controlling a plurality of connected continuous paper printing machines connected in series prevent difference in rotational speeds of the connected printing machines from causing the paper between the printing machines from piling up or tearing. Signal generators count the number of sheets of continuous paper entering each printing machine. The difference in the number of sheets entering each printing machine is calculated and compared to preset upper and lower limits. If an upstream printing machine turns faster than a downstream printing machine, slack will develop in the paper between the printing machines, and the difference between the sheets entering the upstream printing machine and sheets entering the downstream printing machine will be a (+) value. When a preset upper limit is reached, a controller will temporarily stop the upstream printing machine until the downstream printing machine takes up all the slack.

  • Patent number: 4895361
    Abstract: A sheet-fed press includes a front guide device which performs a positional adjustment of a printing sheet before transferring it to a transfer drum. In order to adjust an image forming portion on the printing sheet, both ends of a front guide rod are moved independently of each other. Moving distances of the both ends of the rod are computed by a central processing unit on the basis of a paper size, etc.

  • Patent number: 4884762
    Abstract: A bail arm turning mechanism in a spinning reel is disclosed. The spinning reel has first and second ears for pivotally supporting a bail arm lever and bail arm cam, respectively, to which each end of the bail arm is connected. A manual operation lever is pivotally supported to the first ear, and a rotational lever is provided in the first ear. The rotational lever has front, intermediate and rear portion. The front portion is engageable with the bail arm lever, and the rear portion is abuttable to the manual operation lever. Upon manipulation of the manual operation lever, the rear portion of the rotational lever is pivotally moved about an axis of the intermediate portion, so that the front portion pivots, to thereby rotate the bail arm lever, to thus provide bail arm turning.

  • Patent number: 4881699
    Abstract: A spinning type fishing reel having a projection on the inside of the rotor disposed to selectively engage a spring loaded pivoting lever arm. The arm is engaged with a lever and rotation of the arm by means of the lever engages the pivot arm with the projection on the rotor. This prevents unwanted rotation of the rotor during use of the reel.

  • Patent number: 4879950
    Abstract: A mechanism for adjusting an image position on a printing cylinder in a rotary press adjusts the position by sliding or moving the printing cylinder transversely relative to a rubber cylinder. The mechanism includes a transverse adjusting mechanism and a vertical adjusting mechanism which each have bevel gears. A handle is fixed to a central shaft of the printing cylinder at one side of the cylinder and outside the housing of the rotary press, so that an operator can adjust the image position without having to go to a second side of the machine frame. In the image adjusting operation, the printing cylinder slides along its axis to adjust the transverse position of the image and the printing cylinder gear slides along its axis to control the vertical position of the image.

  • Patent number: 4864928
    Abstract: A printing machine for printing a continuous slip includes an angularly-movable lifter shaft disposed below a path of feed of the printing sheet, and a lifter fixedly mounted on the lifter shaft for angular movement therewith toward and away from the underside of the printing sheet. An urging device normally urges the lifter away from the printing sheet. A first tension applying device is operatively connected to the lifter shaft and is operable to angularly move the lifter shaft together with the lifter against the bias of the urging device so as to bring the lifter into engagement with the underside of the printing sheet to apply tension to the printing sheet when impression and blanket cylinders are spaced from each other, thereby preventing a slack developing on the printing sheet.

  • Patent number: 4860651
    Abstract: In a multi-color printing machine, a skew or slant of a picture to be printed is corrected by cocking, namely, swinging a paper-feed cylinder relative to a base impression cylinder by a unique but simple cocking mechanisms. The cocking mechanism includes a shaft holder which holds one end portion of the shaft of the paper-feed cylinder and which is pivotable about an eccentric position disposed on an imaginary line extending between central axes of the paper-feed cylinder and the base impression cylinder. The shaft holder is connected at another end thereof to an operating shaft via screw means which converts rotation of the operating shaft into the pivotal movement of the shaft holder.
