  • US Patent:
    42533929, Mar 3, 1981
  • Filed:
    Apr 9, 1979
  • Appl. No.:
    6/027951
  • Inventors:
    Fred Y. Brandon - Lexington KY
    Jack P. Chang - Boulder CO
    William D. Clark - Longmont CO
    Eugene G. Stahlberg - Boulder CO
  • Assignee:
    International Business Machines Corporation - Armonk NY
  • International Classification:
    B30B 300
    B02C 1108
    B60B 900
    B21B 702
  • US Classification:
    100155R
  • Abstract:
    An electrophotographic copier machine with a roll fuser where one of the mating rolls is comprised of a thin outer shell which takes a variable taper so that a concave shape is produced under high humidity conditions and a relatively straight roller is produced under low humidity conditions. Means for changing the support at the roll ends is provided to produce the variable taper. End plugs can be moved axially inward at high humidity to provide support for the end portions of the normally concave roll and can be moved axially outwardly under low humidity such that no support is provided until the roll ends are flattened under the pressure of a mating roll.

  • US Patent:
    47566876, Jul 12, 1988
  • Filed:
    Feb 13, 1987
  • Appl. No.:
    7/014745
  • Inventors:
    Charles Cabrera - Longmont CO
    Reid W. Gunnell - Berthoud CO
    Glenn E. Siemer - Boulder CO
    Eugene G. Stahlberg - Longmont CO
  • Assignee:
    International Business Machines Corporation - Armonk NY
  • International Classification:
    F27B 928
  • US Classification:
    432 60
  • Abstract:
    An electrophotographic hot roll fuser is manually movable from an operative position within an electrophotographic reproduction device, to an inoperative position where the fuser is available for cleaning, inspection or sheet jam clearance. When the fuser is in its inoperative position, a manually operable handle is accessible for operation. Operation of this handle moves various operating components, such as sheet guides, apart, thereby facilitating manual sheet jam clearance. Subsequently, when the handle is manually returned to its original position, all sheet guides and like components are accurately relocated to their original operative positions.
