A trommel cleaner apparatus having a non-circular rotatable shaft with a plurality of flapper elements mounted thereto for wiping and cleaning engagement with a trommel is provided herein. The flapper elements each have a hub having inner and outer surfaces, with the outer surface including a plurality of flappers extending therefrom so as to engage a trommel in cleaning operation and with the inner surface including a plurality of indexing lobes to variably position the flapper element relative...

Vacuum cleaner including a unit, comprising an electric motor and an associated suction fan, and a suction nozzle (36) connected to the inlet side of the unit via a dust separating device (15), either directly or via a connectable rigid conduit (13). The vacuum cleaner comprises a handheld unit (10) which when not in use is arranged to be positioned on a stationary storage unit (11), said handheld unit (10) incorporating the said unit and the dust separating device (15) and being provided with a...

A denture cleaner powered by a stream of falling water. A first rotary brush is geared to the gear. A second rotary brush is arranged at an angle to the first brush, with the bristles of the two brushes intersecting. The water falls onto a turbine or water wheel, which turns the first brush through a reducing gear. The first brush frictionally or interfittingly drives the second brush. Dentures are placed between the two brushes, and are held in place by the configuration of the cleaning chamber...

A vacuum cleaner with a steam generator and a source of water under pressure has a suction hose connecting the suction head with the turbine and a dirt collector. Steam and pressurized water lines extend along the hose and the steam line runs to an orifice strip in a sole plate of the head while the spray nozzles are provided in a slot between a pair of brushes. The suction nozzle opens at a slot in the sole plate and sealing strips are provided along the longitudinal sides of the suction nozzle...

The present invention relates to vacuum systems and more particularly, to systems for cleaning up waste materials and/or recovering materials which might otherwise be considered waste, particularly in industrial uses. The instant invention includes a means for creating and applying a vacuum to a localized area, means for collecting materials and a pair of annular rings connected by a spacer means arranged so as to prohibit retained materials from entering the vacuum creation means and means for ...

An air cleaner (10) includes a housing (12) having a first section (14) and a second section (16). The first and second sections (14) and (16) are rotationally adjustable relative to one another. Alignment teeth (42) and (60) engage one another to position the two sections (14) and (16) relative to one another. Buckle type clasps (60) engage a ridge (44) to cam together the sections (14) and (16) and lock them in sealed engagement. A mounting bracket (80) includes a somewhat flexible band (82) w...

A vacuum cleaner is disclosed. The vacuum cleaner includes a motor casing to receive a driving motor with an air outlet through which air from a dust collecting chamber flows. The vacuum cleaner includes a cleaner body with a driving chamber that receives the motor casing therein. An air discharge unit is disposed at the cleaner body through which air which flows from the motor casing of the driving motor is discharged to an outside of the driving chamber. Noise reduction is achieved by guiding ...

An air cleaning device includes a bulb-shaped casing provided at one end with an attached portion to be attached an attaching portion and connected to a commercial power source and at the other end with an outlet, an ozone generator accommodated in the casing and an air supply portion formed in the casing for supplying air into the ozone generator. The ozone generator includes a needle first electrode having a distal end directed to the outlet and a cylindrical second electrode concentric with t...

A cyclone vacuum cleaner including a plurality of cyclone chambers arranged in a group. The cyclone chambers are configured such that frequency characteristics of noises generated from respective cyclone chambers are different from each other.

The invention is directed to a floor cleaner apparatus, such as a vacuum cleaner, including a housing have a particle retaining element and a head operably connected to the housing. The head features an intake port through which dirt and other particles enter the head and a motor and fan assembly that creates suction during operation. A passageway or duct extends between the intake port through the motor and fan assembly. Within the duct, an internal divider forms a plurality of discrete intake ...
