Patent number: 7572307Abstract: A filter apparatus and a vacuum cleaner incorporating the filter apparatus are disclosed. The filter apparatus has a first, fine filter assembly and a second, coarse filter assembly. The fine filter assembly includes a body defining a central aperture in which a pleated fine filter element is arranged. The periphery of aperture is surrounded by a resilient rubber sealing member. Apertures are arranged around the body portion radially outwards of the aperture and sealing member for mounting the fine filter assembly to pins on housing of the vacuum cleaner. The body is also provided with radially inwardly facing slots for engaging corresponding projections on a coarse filter assembly for removably mounting the coarse filter assembly to the fine filter assembly. The removable coarse filter assembly gives the user a choice between two stage filtration (i.e. using the fine and course filter assemblies) or single stage filtration (i.e. using the fine filter assembly only).Type: GrantFiled: January 31, 2005Date of Patent: August 11, 2009Assignee: Black & Decker Inc.Inventor: Eric Coburn

Publication number: 20050011038Abstract: A vacuum cleaner 2 has a housing 4 having primary air outlets 20 defined in a bottom surface of the housing 4 to direct air downwardly and rearwardly of the housing. A fan 26 draws dirty air into the inlet 38, through a filter and most of the filtered air passes out of primary outlets 20. As a result, the air is not vented on to the face and hands of the user, and at the same time avoids disturbing dirt on the surface to be cleaned. A small amount of the air passes between the clamshell halves 10, 12 that make up housing 4, and out of the secondary outlets 28 in the side surfaces of the body portion 6. This air is used to cool the motor, but the rate of air flow out of the secondary outlets is insufficient to cause irritation to the user.Type: ApplicationFiled: June 28, 2004Publication date: January 20, 2005Inventor: Eric Coburn

Patent number: RE40542Abstract: A dual filter arrangement for a vacuum cleaner for filtering particles of dust and debris from an airflow passing through the vacuum cleaner. The dual filter comprises a coarse pre-filter having an array of pores formed therein of substantially uniform diameter and a fine primary filter which is located rearwardly of the pre-filter in the direction of flow of the airflow. The dual filter is releasably latched to a main housing portion of the vacuum cleaner housing. A nose cone is removably secured to the housing and circumscribes the dual filter assembly. The dual filter enables even more efficient filtering of contaminants from dust and dirt entrained air ingested by the vacuum cleaner. Attachment of the dual filter to the main housing portion provides the additional advantage of increasing the capacity of the nose cone and eliminating the need for the user to handle the dual filter assembly when emptying contaminants collected within the nose cone.Type: GrantFiled: April 15, 2005Date of Patent: October 21, 2008Assignee: Black & Decker Inc.Inventors: Eric Coburn, Danny Bone, Barry Pears
