Patent number: 7547153Abstract: A movable blade unit is fixed to a cutter release lever. The cutter release lever is attached to an upper frame by a cutter supporting point shaft so as to freely oscillate. A latch lever holding the upper frame at a closed position and a cutter lock lever locking the cutter release lever are integrated, and are coupled by an opening and closing lever.

Most of the blade holding units are intended for use with mat board, but some can be used to cut and trim sheet-like glass or plastic framing material. Each blade holding unit is also capable of vertical adjustment relative to the workpiece so that various depths of cut can be provided. The method of cutting a mat board permits the mat board to be positioned face up on the base board of the cutting apparatus and does not require flipping or taping of the mat board during V-groove cutting operations.Type: GrantFiled: January 14, 1999Date of Patent: October 31, 2000Assignee: John Knoell & Sons, Inc.Inventor: William A.

Patent number: 6105480Abstract: An apparatus for separating a ribbon-coated multicore optical fiber at a plurality of positions at once, wherein the ribbon-coated multicore optical fiber includes a number of single-core fibers arranged in parallel. This apparatus comprises a first cutting member in which a plurality of sets of arc faces opposed to each other by way of a through path for inserting the ribbon-coated multicore optical fiber are disposed along the through path, while the arc faces in the respective sets extend from one side section of the through path halfway through the width direction of the through path; a second cutting member having a plurality of arc faces which continuously extend to and are adapted to join with the respective arc faces of the first cutting member in the width direction of the through path; and guide members which are respectively disposed at both end positions of the through path so as to position the ribbon-coated multicore optical fiber inserted into the through path.Type: GrantFiled: March 5, 1997Date of Patent: August 22, 2000Assignees: Sumitomo Electric Industries, Ltd., Nippon Telegraph and Telephone CorporationInventors: Keiji Osaka, Hideyuki Iwata

Patent number: 6079307Abstract: A paper cutter having a paper stand, a pair of arms of identical length attached to the paper stand defining a contacting position and a separating position, a guide rail connected to the pair of arms such that the guide rail is parallel to the paper stand, a slider slidably attached to the guide rail. The slider has a rotary blade fixed on a holder, the blade being capable of being moved up and down within the slider against a spring, the blade exposed by being pushed down when the slider is in the contacting position, and a stopper, with a top end and a heavy end, which rotates automatically on a shaft due to its heavy end, hooking the top end on a projection provided on the slider to prevent the rotary blade from being projected from the slider when the guide rail is rotated to the other than the contacting position.Type: GrantFiled: October 21, 1998Date of Patent: June 27, 2000Assignee: Carl Manufacturing Co., Ltd.Inventor: Makoto Mori

Patent number: 6076442Abstract: A new type of multi-chopper for cutting strands or ribbon shaped material such as strands of glass fibers, and a method of using this chopper, is disclosed. The chopper has at least two chopper assemblies on a rotating frame. When one chopper assembly needs repair, the frame is rotated which brings a rebuilt or repaired chopper assembly into operating position quickly and also brings the assembly needing repair into a position where it can be worked on while the other chopper is operating resulting in much reduced downtime. The frame of the chopper can rotate around a vertical or horizontal line, or around a line passing through two opposite corners of a frame.Type: GrantFiled: July 20, 1999Date of Patent: June 20, 2000Assignee: Johns Manville International, Inc.Inventors: Russell D. Arterburn, Randall C. Bascom, Shawn E. Dennis, Douglas J. Kempski

Patent number: 6035754Abstract: A compound miter saw includes a table on which a workpiece is placed, a miter saw unit supporting a saw blade, and a housing pivotally supporting the miter saw unit related to the table in such a manner that the miter saw unit is at least laterally pivotable. Further, the miter saw includes a bevel mechanism for selectively determining the lateral position of the miter saw unit at any of a plurality of pivoted positions, including a vertical position where the saw blade is positioned substantially vertically relative to the table, and leftward and rightward pivoted positions where the blade is inclined laterally leftwardly and laterally rightwardly from the vertical position. The bevel mechanism includes a movable rod and three fixed stop members, the rod being operable to move between a first rod position abutting one of the fixed stop members and a second rod position not abutting the one of the fixed stop members so as to permit the lateral pivotal movement of the miter saw unit.Type: GrantFiled: February 3, 1999Date of Patent: March 14, 2000Assignee: Black & Decker Inc.Inventors: William R. Stumpf, Mark E. Brunson, Scott M. Livingston, Michael L. O'Banion, Robert G. Moores, Jr., John W. Miller, Daryl Meredith, Thomas Kaye, William G. Harman, Jr., Adan Ayala

Patent number: 6016733Abstract: A card corners cutter includes a body having a top surface with two sides and a bottom, the two sides each having a tube attached thereto in which a spring is received. Two guides extend upwardly from two sides the top surface. A passage and a slot are respectively and transversely defined through the body. A working surface is defined in the top surface and located lower than the top surface so as to fixedly position a first knife member on the working surface. A recess is defined in the bottom of the body and communicates with the passage and the slot. A first pin and a second pin are respectively received in the passage and the slot. A torsion spring is mounted to the first pin. A handle is pivotally connected to two ends of the second pin and is limited by the two guides.Type: GrantFiled: January 14, 1998Date of Patent: January 25, 2000Inventor: Chien-Fu Lin
