Patent number: 11912449Abstract: To provide an article gripping system that reduces the installation area of the apparatus and further shortens the amount of time from when it grips to when it feeds articles. An article gripping system (110) switches between a first positional relationship in which a container (50) obstructs discharge of articles gripped by a first gripping unit (15A) but does not obstruct discharge of articles by a second gripping unit (15B) and a second positional relationship in which the container (50) obstructs discharge of articles gripped by the second gripping unit (15B) but does not obstruct discharge of articles gripped by the first gripping unit (15A), so the gripping units do not move while they are holding the articles, and the articles can be prevented from falling out of the gripping units (15).Type: GrantFiled: March 16, 2021Date of Patent: February 27, 2024Assignee: ISHIDA CO., LTD.Inventors: Hiroshi Okano, Shuichi Maeda, Yuki Furukawa, Masaaki Hojo, Akihito Suzuki, Kousuke Watanabe

Patent number: 8132396Abstract: A lawnmower capable of being switched between a bagging mode and a mulching mode is disclosed. The lawnmower includes a shutter mechanism provided on an internal peripheral surface of a housing which opens downward for storing a cutting blade. The shutter mechanism is switched, by the operation of the shutter mechanism, between a bagging mode for delivering cut grass from the housing to a cut grass storage container and a mulching mode for discharging the cut grass out below the housing. The shutter mechanism has a kicker on a shutter body positioned in the interior of the housing. The kicker guides the cut grass to the bottom of the housing during the mulching mode.Type: GrantFiled: June 2, 2010Date of Patent: March 13, 2012Assignee: Honda Motor Co., Ltd.Inventors: Fumio Minami, Kenzo Shimada, Hiroshi Kobayashi, Hiroshi Hojo, Shuhei Maruyama

Patent number: 7850555Abstract: Apparatuses and methods are disclosed for controlling a variable speed transmission including an actuator, a cam follower, and a speed adjustment cam. The actuator is rotatable through a first phase and a subsequent second phase, and includes an actuator cam surface and a variator. The cam follower is movable in response to contact with the actuator cam surface during rotation through the first phase, for actuating a coupler of the transmission between a disengaged position and an engaged position. The variator is movable along the speed adjustment cam during rotation through the second phase for enabling adjustment of a torque transfer mechanism associated with the transmission. By this configuration, control over the coupling of the transmission to a torque input such as a motor and control over the speed of the transmission are both enabled through rotation of a single actuator, and thus can be implemented in a self-propelled machine such as a lawnmower using a single operator-manipulated control.Type: GrantFiled: July 30, 2004Date of Patent: December 14, 2010Assignee: Honda Motor Co., Ltd.Inventors: James C.

Patent number: 6827068Abstract: A lubrication and breather system for an engine that is generally adapted for use as either a vertically-oriented crankshaft-type engine or a horizontally-oriented crankshaft-type engine. The crankcase has first and second bearing bosses supporting first and second journal portions of the crankshaft. The second bearing boss lies above the first bearing boss when the engine is of the vertical-type. The system includes a cap that is secured over the second bearing boss and cooperates with the second bearing boss to define an annular chamber for receiving splashed oil produced in the crankcase. The cap has a plurality of ribs formed thereon that reduce an amount of oil, which is entrained in the blow-by gas, sent from the annular chamber to the breather chamber. The second bearing block includes an oil feed hole, a plurality of oil sumps, and a plurality of oil return holes, with the oil return holes being of relatively smaller size. Each of the oil sumps is associated with one oil return hole.Type: GrantFiled: February 20, 2004Date of Patent: December 7, 2004Assignee: Honda Motor Co., Ltd.Inventors: Shigekazu Sakata, Brian Doklovic, Shinji Katayama, Hiroshi Hojo, Tetsuya Kobayashi

Patent number: 6729116Abstract: An apparatus and method for adjusting the height of a wheel, particularly a caster wheel, in relation to a structure such as a mower deck of a lawnmower includes a frame member, a hollow guide member, a transverse element, and a lever. The frame member is interconnected between one or more caster wheels and the structure. The frame member includes an angled section disposed along an angled adjustment direction. Spaced recesses are formed in the angled section and arranged along the adjustment direction. The guide member and transverse element are attached to the structure. The angled section is slidable through the guide member. The lever is pivotably connected to the transverse element and includes a locking element. By pivoting the lever, the locking element can be brought into engagement with a selected one of the recesses to fix the angled section at a desired position relative to the guide member and thus the height of the structure relative to a ground surface over which the caster wheel or wheels roll.Type: GrantFiled: March 28, 2003Date of Patent: May 4, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: George B.
