Vacuum cleaning appliances
First Claim
1. A vacuum cleaning appliance comprising:
- a main casing having an air passageway therein containing a motor driven suction fan unit,a floor engaging section containing a first inlet for dirt laden air and selectively communicating with said passageway,a second inlet for dirt laden air selectively communicating with said passageway, said second inlet comprising a socket,a tubular member having a first end coupled to said socket and a second end,a hollow pipe member at least partially housed within said tubular member, a lower end of said pipe member being detachably inserted into or removed from said socket, said lower end of said pipe member being connected with said socket through said tubular member when removed from said socket, an upper end of said pipe member extending beyond said second end of said tubular member and forming a handle for said appliance when said lower end of said pipe member is inserted into said socket, anda valve device operable in response to the insertion into or removal from said socket of said pipe member for connecting said passageway selectively with one of said first and second inlets.

Abstract
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.
