  • Patent number: 4268288
    Abstract: A cyclone separator-type vacuum cleaner. The vacuum cleaner has a cylindrical housing having three sections. Each section of the housing is joined to an adjacent section by latches provided on the housing. By releasing the latches the internal mechanisms of the vacuum cleaner can be easily accessed for cleaning or maintenance. The vacuum cleaner has a first baffle that is funnel-shaped and a second baffle in the form of an outwardly-flared skirt member. The skirt member is attached at the base of the funnel-shaped baffle. The two baffles together form an exhaust path through their center through which the incoming air exits after the dirt has been separated therefrom. The funnel-shaped first baffle directs the incoming dirt-laden air inwardly in a circular path of decreasing cross-sectional area so that the speed of the circulating air is increased, causing centrifugal separation of dirt.
