Patent number: 9114597Abstract: A prong style file fastener and the method of manufacture is disclosed which has a protective element to prevent damage to paper documents and personal injury. In one embodiment, the prongs of the fastener are covered with a heat shrinkable sheath. In another, the prongs are overcoated with a powder coating which is melted thereon. A method of applying the sheath to the prongs uses a pair of jaws or V-shaped surface to drive the sheath onto the prongs.Type: GrantFiled: May 9, 2014Date of Patent: August 25, 2015Assignee: Smead Manufacturing CompanyInventors: Harold Peter Lindelof, Marvin J.

Patent number: 8540138Abstract: A stair-step, expandable file folder is disclosed, in which each pocket in the folder has the same depth, rather than the back pockets being deeper than the front pockets. The folder includes a series of dividers that form the front and back sides of the pockets of the folder. The top edges of the dividers have increasing height, from the front to the back of the folder. The dividers are folded to form the bottoms of the pockets, with the folded portions also increasing in height from the front to the back of the folder. Each divider extends downward to form the back face of a pocket, is folded forward to form the bottom face of the pocket, and is folded downward to extend toward the bottom edge of the folder. The troughs in an expandable gusset support the sides of the dividers. Above the fold portion, the divider laterally extends into one trough. Below the fold portion, the divider laterally extends into the adjacent trough toward the front of the folder.Type: GrantFiled: November 1, 2010Date of Patent: September 24, 2013Assignee: Smead Manufacturing CompanyInventors: Duane Christensen, Tim Blegen, Dennis Bowen, Harold Peter Lindelof

Patent number: 8425387Abstract: A stair-step, expandable file folder is disclosed, in which each pocket in the folder has the same depth, rather than the back pockets being deeper than the front pockets. The folder is formed from a group of attached dividers. Each divider in the group is generally planar and includes two horizontal folds near a bottom edge of the divider. The divider area above the folds forms a wall of a pocket. The divider area between the folds extends to an adjacent divider and forms the bottom of the pocket. The divider area below the folds is attached to the adjacent divider. The adjacent divider forms an opposing wall of the pocket. When the group of dividers is compressed front-to-back, the dividers all have the same lateral footprint. When the group is expanded front-to-back, the dividers translate vertically, so that the tops of the dividers are all visible simultaneously from the front of the folder.Type: GrantFiled: November 1, 2010Date of Patent: April 23, 2013Assignee: Smead Manufacturing CompanyInventors: Duane Christensen, Tim Blegen, Dennis Bowen, Harold Peter Lindelof

Patent number: 7182330Abstract: Disclosed herein is a sheet feeder for a printer. The sheet feeding device feeds a single sheet into an infeeder of a printer without communicating with the printer. The sheet feeder is equipped with a sensor for detecting when the printer is able to accept a sheet. The sheet feeder is equipped with a programmable timing device that causes the sheet feeder to wait a predetermined amount of time before inserting another sheet into the printer. The predetermined amount of time corresponds to the amount of time needed for the printer to complete printing on a sheet after the sensor has detected that the printer is able to accept a sheet into the infeeder of the printer. The sheet feeder is configured with a gate having an adjustable gap in close proximity to a tray containing a stack of sheets. The gate permits only a single sheet to be fed into the infeeder of the printer at a time.Type: GrantFiled: December 9, 2002Date of Patent: February 27, 2007Assignee: Smead Manufacturing CompanyInventors: Harold Peter Lindelof, Leon David Wirth
