Vacuum cleaning appliances
First Claim
1. A vacuum cleaning device convertible alternately, into an upright cleaning appliance and into a cylindrical tank type appliance, said appliance comprising a suction head adapted to be moved over a surface to be cleaned when the appliance is in its upright mode, a first housing having one end pivotally connected to said suction head and having an opposite end, a second housing having a first end fixed to said opposite end of the first housing, a pair of frusto-conically shaped cyclones disposed side by side and enclosed by said second housing, each of said cyclones having a first open end facing said first housing and a larger opposite end, a flexible hose connecting said suction head with one of said frusto-conical cylones for flow of air into the said frusto-conical cyclone, means connecting said side-by-side cyclones for flow of air therebetween, a motor and fan assembly disposed in said first housing for sucking air into said suction head and into said flexible hose, means disposed above each of said first open ends of the frusto-conically shaped cyclones within the said second housing comprising an inverted conically shaped member disposed above the smaller open end of each of the cyclones with its apex facing said smaller open end to interrupt flow of air through the said smaller open end and intercept suspended solids in the air, means comprising third and fourth housings disposed around the cyclones for directing intercepted solids falling from the air towards the first suction head and into a receptacle therefor, means on the first housing for rollably supporting the appliance in its upright mode, and a rotary brush supported across said suction head to contact said surface as the appliance in its upright mode is moved over the surface to be cleaned,means for moving the applicance in its upright mode comprising a pair of wheels rotatably mounted on said first housing;
- means fixed to said second housing for lifting and moving the appliance while in its cylindrical tank type mode.

Abstract
The invention relates to vacuum cleaning appliances.
The appliance of the invention includes a cyclone unit which is operable to extract dust and other dirt from the air flow therethrough and to deposit the extracted dust and other dirt in a chamber outside the cyclone and separate from the air flow through the casing of the appliance. The extracted dirt is removed from the appliance by separation of the cyclone unit from the casing.
The appliance is convertible to act both as an upright type cleaner or a cylinder type cleaner.

1. A vacuum cleaning device convertible alternately, into an upright cleaning appliance and into a cylindrical tank type appliance, said appliance comprising a suction head adapted to be moved over a surface to be cleaned when the appliance is in its upright mode, a first housing having one end pivotally connected to said suction head and having an opposite end, a second housing having a first end fixed to said opposite end of the first housing, a pair of frusto-conically shaped cyclones disposed side by side and enclosed by said second housing, each of said cyclones having a first open end facing said first housing and a larger opposite end, a flexible hose connecting said suction head with one of said frusto-conical cylones for flow of air into the said frusto-conical cyclone, means connecting said side-by-side cyclones for flow of air therebetween, a motor and fan assembly disposed in said first housing for sucking air into said suction head and into said flexible hose, means disposed above each of said first open ends of the frusto-conically shaped cyclones within the said second housing comprising an inverted conically shaped member disposed above the smaller open end of each of the cyclones with its apex facing said smaller open end to interrupt flow of air through the said smaller open end and intercept suspended solids in the air, means comprising third and fourth housings disposed around the cyclones for directing intercepted solids falling from the air towards the first suction head and into a receptacle therefor, means on the first housing for rollably supporting the appliance in its upright mode, and a rotary brush supported across said suction head to contact said surface as the appliance in its upright mode is moved over the surface to be cleaned,
means for moving the applicance in its upright mode comprising a pair of wheels rotatably mounted on said first housing; means fixed to said second housing for lifting and moving the appliance while in its cylindrical tank type mode. - View Dependent Claims (2, 5, 6, 7, 8)
- 3. A vacuum cleaning appliance comprising a cleaner head for engaging a carpet or the like to be cleaned, a main casing connected to the cleaner head by an inlet passageway, and a motor casing enclosing a motor driven fan unit, means detachably connecting said main casing to said motor casing comprising a central rod operable externally of the main casing to engage the motor casing and secure the main casing and the motor casing together and allow separation thereof, said fan unit being operable to draw dust and dirt laden air from the cleaner head through the inlet passageway into the main casing, first and second frusto-conically shaped cyclone units each having a first end and a second larger end disposed in series in an air passageway through said main casing, means for air to enter tangentially into the first cyclone unit through said larger end, said cyclone unit being operable to extract dust and dirt from air flowing throughthrough and deposit it in a chamber separate from the air passageway.
