Patent number: 8139981Abstract: A cleaning station for removing particulate material from a moving web in an electrographic printer/copier includes a customer-replaceable web-cleaner device with a support bracket/backup shoe assembly. A quick disconnect feature enables the cleaner cover to be de-coupled from the cleaner body to allow the debris to be easily removed with replacing the web-cleaner. The cleaner has a cleaner sump that is spring loaded to force contact of four strategically placed stops in the sump with a stationary back up shoe assembly allowing for higher precision of blade engagement with a transport web or a photoconductor. The web-cleaner has two wiper blades, each having each having a distinguishment such that the distinguishment distinguishes one wiper blade from the other wiper blade when the blades are locked into the cleaner sump by springs, to facilitate material removed from the web. The wiper cleaning blades and the cover assembly are easily replaceable by the operator in the correct order.Type: GrantFiled: January 22, 2008Date of Patent: March 20, 2012Assignee: Eastman Kodak CompanyInventors: Francisco L.

Patent number: 6900436Abstract: A wire tensioning mechanism for tensioning a wire having an end one and an end two in a machine in which the wire has a means for attachment on end two and is fixed to the machine at end one, comprises a slide block, and a spring. The slide block is slidably mounted to the machine at end two of the wire, such that the slide block slides parallel to the wire. The slide block has a slot which is wider than the wire but narrower than the means for attachment, such that when the slide block is mounted on the machine, the wire end two can be slid into the slot such that pulling the slide block in the direction away from the wire forces the means for attachment against the slot, but does not allow the means for attachment to pass through. The slot is lined up with the wire such that when the wire is in tension, there are no side loads on the means for attachment.Type: GrantFiled: October 14, 2000Date of Patent: May 31, 2005Assignee: Eastman Kodak CompanyInventors: Daniel R. Palmer, Gary B. Bertram, Warren G. Branch, III

Patent number: 6868242Abstract: The present invention relates in general to a corona charger for use in an electrostatographic reproduction apparatus or the like, and more particularly to a cleaning mechanism for the corona wires of a corona charger. According to one aspect, a corona wire assembly is provided having a corona wire and a cleaning pad with a hole, the corona wire extending through the hole. According to another aspect, a method for cleaning a corona wire is provided wherein relative movement is generated between a corona wire and a cleaning pad having a hole, the corona wire extending through the hole. According to a further aspect, a cleaning mechanism for cleaning the surface of a corona wire within a corona charger is provided having a cleaning pad, a corona wire passing through the cleaning pad and positioning the cleaning pad in at least one direction lateral to the corona wire, and a holding member holding the cleaning pad without restraining the cleaning pad in the at least one direction lateral to the corona wire.Type: GrantFiled: March 25, 2003Date of Patent: March 15, 2005Assignee: Eastman Kodak CompanyInventors: George R. Walgrove, III, Gary B. Bertram, Gerald M. Darby, II, Daniel R. Palmer

Publication number: 20020150411Abstract: A transfer roller 42 is positioned about a castor axis C and a gimbal axis G. When the gimbal lock 102 is turned, an angle bracket 150 absorbs adverse torque. The angle bracket has one leg 151 fixed to the holding bracket 100 of the transfer assembly. The angle bracket is slid until the upper leg 152 contacts the machine bracket 82. The angle bracket is thinner than the support bracket 82 and deforms when the gimbal lock is turned to fix the transfer assembly 40 to the support bracket 82. The angle is 90 degrees or greater.Type: ApplicationFiled: February 26, 2001Publication date: October 17, 2002Inventors: George R. Walgrove, Gary B. Bertram, Daniel R. Palmer
