Patent number: 6766560Abstract: The Gutter Leaf-Blower is an apparatus conceived to clean rain gutters. The objective is to provide the operator with a user ‘friendly’ means of blowing leaves out of gutters while operating from ground level. The objective was accomplished by mounting an air nozzle on one end of a small lightweight, 6-8 foot rigid tube assembly and, in turn, connecting the input of the air nozzle to the output of an air blower with a flexible air hose. This configuration offers flexibility in the it allows the operator to control the position of the air nozzle relative to the gutter with the extension tube assembly without requiring movement of the blower unit. With this approach, the user can operate from ground level and control the position of the nozzle with either hand while holding the air blower with the other hand like a suitcase.Type: GrantFiled: December 9, 2002Date of Patent: July 27, 2004Inventor: Milford R.

Publication number: 20040117940Abstract: Disclosed is a vacuum cleaner capable of collecting at one place external air absorbed in the interior of the main machine through the absorption motor, exhausting the collected external air using strong blasting force. Usually, in case that dusts exist on the corner section or the gap section upon cleaning of the bottom part with use of the vacuum cleaner, a user could not bring the absorption nozzle close to the dusts accumulated section and sucking force does not reach that dust accumulated section, whereby the dust gets difficult to wipe out. Therefore, the vacuum cleaner has the closed space part in the internal rear part of the main machine in which the absorption motor is installed, and has, in the closed space part, the exhausting hole to which the blasting nozzle is joined in a free attaching and detaching manner.Type: ApplicationFiled: March 18, 2003Publication date: June 24, 2004Inventor: Dong Hwan Kim

Publication number: 20020166195Abstract: Leaf blower that is carried on the back of the operator comprising at least an engine (14) and a fan. The fan is provided with an air inlet (13) placed on the side of the fan that is facing away from the back of the operator. The air stream is passing the engine (14) on its way to the air inlet (13) so that the engine (14) is cooled.Type: ApplicationFiled: May 6, 2002Publication date: November 14, 2002Applicant: Aktiebolaget ElectroluxInventors: Goran Dahlberg, Gustaf Doragrip, Peter Gunnarsson, Marcus Kragner, Anna Sjogren, Esbjorn Ollas

Publication number: 20020166197Abstract: A position shifting plate for an air blowing device includes a casing having an inlet defined in an underside of the casing and an outlet defined in an end of the casing. An annular neck extends from the underside of the casing and encloses the inlet. A gap is defined between the underside of the casing and the neck. A guide member extends from the underside of the casing. A shifting plate has a netted portion and a hole. A flange extends from the shifting plate and two rails extend inward from the flange so as to be movably inserted in the gap. The shifting plate movably contacts the guide member to shift the hole or the netted portion to cover the inlet of the casing.Type: ApplicationFiled: May 14, 2001Publication date: November 14, 2002Applicant: Jenn Feng Industrial Co., Ltd.Inventor: Jung-Chang Jong

Publication number: 20020157208Abstract: A nozzle for an air blower of a car wash installation is designed to be adjustable to vary the direction of the air flow delivered by the blower. The blower has a tapered frusto-conical nozzle that is oblique and is rotatably mounted at its base about an outlet of the blower. Upon rotation of the nozzle the direction of the delivered air flow moves in a conical path. Automated controls are provided to direct air flows from blowers in predetermined directions in the dryer section of an automated vehicle wash.Type: ApplicationFiled: April 30, 2001Publication date: October 31, 2002Inventor: Daniel J. MacNeil

Publication number: 20020157210Abstract: These tuned nozzle tip attachments or extension wand modifications are for leaf blowers, workshop or industrial type exhausting vacuums, compressed air guns/extensions, and abatement systems and facilitate a method of dust cloud sweeping. Protection of the operator, coworkers, ventilation systems, and equipment in peripheral areas from most of the back draft, billowing, uncontrollable, peripheral dust that normally occurs with current know art is greatly enhanced. By rapidly aspirating, momentarily retaining, continuously recycling and gripping the billowing peripheral cloud of dust/debris back into the primary cleaning air stream at the nozzle point of egress the associated dust cloud that normally occurs is harmlessly dissipated. The elongated deflecting surface contact area achieves this in a manner that provides the utmost operator control and nozzle aspiration of the airborne dust much the same way the airflow around an airplane wing is controlled and provides lift to an aircraft.Type: ApplicationFiled: August 8, 2001Publication date: October 31, 2002Inventor: Michael Randolph Minor

Publication number: 20020157211Abstract: A blower having a fan mounted perpendicularly relative to an airflow discharge port. The fan is disposed within a volute formed in the housing at a rear area of the housing. This places the volute slightly behind the user's leg or hip when the blower is suspended or being held by a user along one side of the user's body. This significantly increases the ergonomics, efficiency and comfort of the blower by allowing the blower to rest more comfortably along the user's side without interference from the volute portion of the housing. This also allows the motor to be located directly underneath the handle of the housing to provide a better balance and feel to the housing when the user is holding onto the blower via the handle.Type: ApplicationFiled: April 27, 2001Publication date: October 31, 2002Inventors: James D. Marshall, Michael A. Milligan, Patrick Wade Mooney

Publication number: 20020157209Abstract: A portable blower device with a housing, a power source, a fan structure and a set of discharge tubes having a rigid discharge tube and a flexible discharge tube. The blower may be selectivley employed in a first condition, wherein the flexible discharge tube is coupled between an outlet in the housing and a proximal end of the rigid discharge tube, and a second condition, wherein the rigid discharge tube is coupled directly to the outlet in the housing.Type: ApplicationFiled: April 27, 2001Publication date: October 31, 2002Inventors: James D. Marshall, Michael A. Milligan, Patrick W. Mooney

Publication number: 20020133899Abstract: An unmanned vehicle for cleaning and disinfecting the floor in a stable such as is used for dairy cattle. The vehicle is provided with a manure displacement device which has an extensible member capable of being moved to locations in the stable remote from the vehicle. The manure displacement device comprises a manure slide and is provided with a pressure setting mechanism to govern the force with which the manure displacement device is active on the stable floor. The manure displacement device may be extendible by a telescopic carrier or an articulated arm which is hingedly mounted to a housing of the vehicle. The vehicle also carries sensors to determine the presence and recent departure of animals in cubicles on the stable floor and for detecting undesired substances including manure on the stable floor.Type: ApplicationFiled: January 24, 2001Publication date: September 26, 2002Applicant: Lely Research Holding A.G. Liability CompanyInventor: Karel Van den Berg
