The apparatus includes a chassis and a reservoir for holding water to be dispensed via a dispensing tube in fluid communication with the reservoir. A scraper assembly attached to the chassis includes a scraper blade adapted to engage the ice surface. A first thrower is rotatably mounted to the chassis adjacent to the scraper blade and a second thrower is rotatably mounted to the chassis adjacent to the first thrower. A snow storage compartment has an opening adjacent the second rotating thrower. The first rotating thrower is adapted to deliver ice or snow accumulated by the blade to the second rotating thrower. The second rotating thrower then delivers the ice or snow to the snow storage compartment. A motor is coupled to the chassis and a drive linkage is coupled to the motor for rotatably driving the first and second throwers.Type: ApplicationFiled: June 6, 2006Publication date: December 6, 2007Inventor: Alain P. Demers

Patent number: 7051461Abstract: A walk-behind working machine has a traveling unit, a working unit, an engine, and an illumination section disposed forwardly of the engine for projecting light. A cover member collectively covers the engine and the illumination section. The cover member has a light transmitting section for transmitting therethrough light projected by the illumination section. The light transmitting section or a portion of the cover member near the light transmitting section has at least one through-hole through which heat generated by at least one of the engine and the illuminating section is radiated.Type: GrantFiled: June 23, 2004Date of Patent: May 30, 2006Assignee: Honda Motor Co., Ltd.Inventors: Tomoki Itou, Hiromi Yuzuriha, Ai Amano, Seishu Sakai, Masatoshi Nagaoka, Takahiro Yamamoto

Patent number: 6948569Abstract: A device for removing material from a surface includes a blade, an auger positioned in close proximity to a front side of the blade and operably mounted on an axle for rotary motion relative to the blade whereby material accumulating at the front side of the blade during movement of the blade over the surface is transversely moved from the front side of the blade to a side of the device by the rotary motion of the auger, and a handle operably connected to the blade for directing the blade and the auger over the surface. The auger has a passage receiving the axle. The auger is preferably rotatable relative to the axle and the axle is preferably rotatable relative to the blade. Preferably, the auger is molded of plastic and the passage is free of a molding draft.Type: GrantFiled: September 16, 2004Date of Patent: September 27, 2005Assignee: UnionTools, Inc.Inventors: Brian J. Conaway, Terry M. Birchler

Patent number: 6904708Abstract: A snow removal system (100) for melting snow into water includes a container (110) having a storage chamber (124) adapted to store snow and a predetermined amount of water (114). The snow removal system also includes a heating assembly (104) at least partially disposed in the storage chamber and adapted to heat water stored in the storage chamber to a selected temperature. The snow removal system further includes a mixing system (106) adapted to pressurize water and discharge the pressurized water through at least one nozzle (168). The nozzle is oriented to direct the pressurized water into the storage chamber. A method of snow removal whereby the snow removal system (100) is used to mix snow with heated water by spraying of pressurized water.Type: GrantFiled: May 29, 2003Date of Patent: June 14, 2005Inventor: Gary A.
