Patent number: 4826515Abstract: A cleaning apparatus including cyclones (11, 52, 81, 107) connected to a uniquely configured receiving chamber (12, 53, 99, 112) is described. The chamber has a diameter furthest from the cone opening (32, 75, 98, 118) at least 3 times the diameter of the cone opening such that dirt is not re-entrained from the chamber. Also described is an apparatus with a sealing member (33, 76, 100, 117) between the receiving chamber and cyclone which provides a seal during air flow and which allows separation of the chamber and cyclone for dirt removal. Also described is a ring second sealing member (34, 104) around an open portion of the receiving chamber which allows removal of the chamber from an outer container (10, 80) to facilitate emptying dirt.Type: GrantFiled: March 3, 1988Date of Patent: May 2, 1989Assignee: Prototypes, Ltd.Inventor: James Dyson

Patent number: RE32257Abstract: This invention relates to a vacuum cleaning appliance which is convertible to act both as an upright type cleaner or a cylinder type cleaner.The main air passageway through the appliance includes a motor driven suction fan unit and a valve device which is operable to connect the passageway either with an air inlet in a carpet engaging section or with an air inlet in a socket for receiving a cleaner head in the form of a hollow pipe which is connected with the socket by a flexible hose. The pipe slides telescopically within the flexible hose so as to engage within the socket and to act as a handle. When located in the socket the pipe operates the valve device to connect the air passageway with the carpet engaging section.Type: GrantFiled: December 3, 1984Date of Patent: October 7, 1986Assignee: Prototypes, Ltd.Inventor: James Dyson
