A handle assembly for securing a vacuum hose to an intake nozzle of a vacuum cleaner system. A handle housing having first and second mating handle housing sections and a plurality of oppositely facing ridges and oppositely facing grooved portions protruding from inner surfaces of the housing sections is adapted to house a ribbed end portion of a vacuum hose and an elbow section having a shoulder portion protruding therefrom. The ridges and grooved portions are adapted to abuttingly engage the ribbed end portion of the vacuum hose and the shoulder portion of the elbow section respectively when the first and second handle housing sections are matingly engaged, to thereby prevent clockwise or counter-clockwise rotation of the vacuum hose as the handle assembly is articulated into various positions during use. The vacuum hose further includes a relatively smooth inner surface which is operable to slide over a portion of the elbow section housed within the handle assembly housing. The elbow operates to grip onto the vacuum hose to further help secure it to the housing. The vacuum hose is thus secured to the handle housing without the need for screws, adhesives or specially formed fittings secured to the end of the vacuum hose.

Handle assembly for a vacuum system cleaning tool

A separator for use in connection with a liquid bath-type vacuum cleaner system. The separator includes an annular, cup-like housing adapted to rotate axially about its vertical axis for generating a centrifugal force to be applied to intake air therein; and a plurality of intake/exhaust slots particulates entrained in the intake air and liquid particulates from a liquid bath to be drawn into an interior area of the housing and coalesce therein, whereby the coalesced particulates are subjected to centrifugal force and are thereby separated from the intake air. The intake/exhaust slots further enable the coalesced particulates to be forcibly expelled from the interior area of the housing therethrough as they are forced radially outwards by the centrifugal force generated by the rapid, axial rotation of the housing.

Separator for a vacuum cleaner system

A separator for use in connection with a liquid bath type vacuum cleaner system. The separator includes an annular, cup-like housing adapted to rotate axially about its vertical axis for generating a centrifugal force to be applied to intake air therein; a plurality of slots on the housing for allowing dust and dirt particulates entrained in the intake air and liquid particulates from a liquid bath to be drawn into an interior area of the housing and coalesce therein, whereby the coalesced particulates will be subjected to centrifugal force and will thereby be separated from the intake air; and a plurality of exhaust slots for allowing the coalesced particulates to be forcibly expelled from the interior area of the housing as they are forced radially outwards by the centrifugal force towards and through the exhaust slots by rapid, axial rotation of the housing. In one preferred embodiment a plurality of elongated slots in the housing provides both an intake and an exhaust function. In other preferred embodiments the intake slots and the exhaust slots are disposed on various portions of the housing to alter the separating characteristics of the separator. The preferred embodiments each further incorporate a removable spider for providing further structural support to the separator, and for further helping to generate centrifugal force within each separator.
