Patent number: 6112631Abstract: A towel dispensing mechanism includes a frame upon which a quantity of paper is stored on a supply reel. An extending portion of paper pulled through an exit slot of the housing rotates a paper feed roller rotatably supported within the frame, causing an attached arm member to engage a knife assembly, and causing a pivoting cutting blade to move into engagement with the paper web after the roller has rotated to a predetermined position. The knife assembly is biased to allow restoration to a precutting position when the arm member no longer engages the knife assembly. According to a preferable arrangement, a vertically disposed intermediately disposed engagement element supported to the frame interconnects the arm member with the knife assembly. Biasing of the arm member causes the feed roller to rotate additionally a predetermined amount after the paper has been cut, thereby metering a predetermined amount of paper from the supply reel through the exit slot.Type: GrantFiled: May 7, 1997Date of Patent: September 5, 2000Inventor: Terrance L. VanAlstine

Patent number: 6089134Abstract: A multi-purpose blind cut-down apparatus for cutting a blind having a head rail and closure elements. The cut-down apparatus has a blind holding plate with a blind component opening and a closure element opening for holding the head rail and closure elements in position for cutting. The cut-down apparatus uses a closure element cutting bar moveable relative to the holding plate for cutting the closure elements extending through the holding plate. The cutting bar has an die opening for receiving a cutting die on a cutting die plate. The die opening and cutting die receive the head rail of the blind and cooperate to cut the head rail by moving the cutting die plate relative to the holding plate. The cutting bar moves in a linear path while the die plate moves in an arcuate path, both the cutting bar and die plate are moved by a transmission element moveable relative to the holding plate.Type: GrantFiled: July 23, 1999Date of Patent: July 18, 2000Assignee: Shade-O-Matic LimitedInventor: Norbert Marocco

Patent number: 6030135Abstract: In a tape cutting mechanism, when a tape is cut manually, a rack 58 which is lowered by pushing a push button 14 down meshes with a gear 48 by guidance of a guide groove 59 to thereby cause a scissors cam 46 to make a single complete rotation along with a pin 46b around a cam shaft 47. The pin 46b half rotates to raise a turnable arm 52b up so that a turnable blade 52a is turned toward a fixed blade 55 to cut a printed tape portion. By the remaining half rotation, the turnable arm 52b is returned to its reference position. When the rack 58 rises with the resiliency of a compression spring 57 due to release of the push button 14 from its pushed state, the rack 58 is disengaged from the gear 48 with the guide of the guide groove 59.Type: GrantFiled: February 9, 1999Date of Patent: February 29, 2000Assignee: Casio Computer Co., Ltd.Inventor: Kazuhide Imai

Patent number: 6026668Abstract: A cylindrical sleeve and a reaction force receiver are fixed on a ceiling plate so as to form a passage along which a rod-like member is placeable and bent by a bending pin rotating about an output shaft driven by an electric motor through a speed-reduction gear train. A wall is formed in parallel with a front end surface of the reaction force receiver in an opposed relationship with each other. A plurality of surfaces, formed on the front end of the reaction force receiver, are inclined with each other. The rod-like member is supported along one of the plurality of surfaces.Type: GrantFiled: May 10, 1999Date of Patent: February 22, 2000Assignee: Hitachi Koki Co., Ltd.Inventors: Hiroyuki Oda, Chikai Yoshimizu, Eiji Nakayama

Patent number: 5931039Abstract: An electric cutting and bending tool that transfers the rotation of an electric motor to an output shaft after slowing the rotation through a gear train. An eccentric cam is provided integrally with the output shaft and drives against a pivot plate. The pivot shaft has one end provided with a cam roller in rolling contact with the cam, another end provided with a movable blade and an intermediate portion provided with a pivot pin. A bending roller is provided on the cam to bend a reinforcing rod about a center pin to a desired angle between 0-180.degree..Type: GrantFiled: April 7, 1997Date of Patent: August 3, 1999Assignee: Hitachi Koki Co., Ltd.Inventors: Chikai Yoshimizu, Kihatirou Matsumoto, Junichi Konishi, Hiroyuki Oda, Nobuaki Hatanaka

Patent number: 5791222Abstract: A tool including two flat parallel flanges (2 and 3), defining between them a space (4) which corresponds to the thickness of a cutting blade (5) and including two symmetrical slots which have profiles that are roughly identical to that of a gutter (7) so as to constitute a guiding cradle for cutting the gutter by operation of the cutting blade (5) between flanges (2 and 3). The guiding cradle is defined by slots delimited in an upper zone by a convex contour (6b) of a fixed part of the flanges, and in a lower zone by the concave contour (6a) of a movable part, so that a movable part can be articulated at one of its ends around a fixed axis of rotation (8) like a jaw (9) in the open position (0), to allow free passage of the gutter (7) and in the closed position (F) constitutes a fixed support for cutting.Type: GrantFiled: May 3, 1995Date of Patent: August 11, 1998Assignee: Dal'Alu S.A.Inventor: Jean Pierre Micouleau

Patent number: 5724876Abstract: A log cutting apparatus having a support frame, a cutting arm, and first and second hydraulic cylinders for pivotally actuating the cutting arm through a cutting arc. The support frame comprises two support members and a removable linking member for easy disassembly and transport of the log cutting apparatus. The support frame includes a cutting arm housing for protecting the cutting arm in a laid back position with the cutting side of the cutting arm disposed upwardly. The cutting arm passes through a vertical during the cutting stroke. The first hydraulic cylinder works in conjunction with a cam-link, actuating the cutting arm from a retracted position within the housing to an intermediate position through rotation of the cam-link. The second hydraulic cylinder actuates the cutting arm from the intermediate position to an extended position during which the actual log cutting is performed.Type: GrantFiled: November 9, 1995Date of Patent: March 10, 1998Assignee: CTR Manufacturing, Inc.Inventor: Calvin S. Johnson

Patent number: 5555832Abstract: A method for manufacturing hosiery items, termed "top-to-top" method, and the related modified knitting and stitching machines. The method includes the following steps: knitting a first hosiery item starting from a top down to a toe; knitting at least one row of trim at the end of the toe; knitting a second hosiery item at the end of the row of trim starting from a second toe up to a second top; separating and stitching the first and second hosiery items initially joined by the trim row by means of a specifically modified stitching machine. The stitching machine includes two independent stitching units which are fed by a common conveyor which is provided with a cutter and with diverging traction means. Top-to-top knitting can be performed with appropriately modified mechanically-programmed machines or with electronically programmed machines.Type: GrantFiled: July 26, 1994Date of Patent: September 17, 1996Assignee: Conti Complett S.p.A.Inventor: Andrea Conti

Patent number: 5520079Abstract: The invention relates to a terminal carrier chipper for chipping a terminal carrier that couples a plurality of terminals in concatenation during the process of fabricating a wire harness used in electrical circuits. The object of the invention is to provide a terminal carrier chipper in simple structure, which is less vibrating and noisy and whose blade section exhibits an improved durability. The terminal carrier chipper according to the present invention includes: a fixed blade 3; a moving blade lever 9; and a rotating cam 5. The moving blade lever 9 is oscillated around a support shaft 10 by rotating the cam 5 while causing a projection 5a of the cam 5 to come in contact with a cam guide 11 arranged on the moving blade lever, so that a blade edge 9c of the moving blade lever nears and leaves a blade edge 3a of the fixed blade 3 to thereby chip a terminal carrier T.Type: GrantFiled: August 26, 1993Date of Patent: May 28, 1996Assignee: Yazaki CorporationInventors: Takamichi Maejima, Kazuhiko Takada
