Abstract: A portable frost and snow removing appliance for use in removing ice and snow from the surfaces of vehicle windows includes an elongated housing having a pistol handgrip at one end and containing an electrically operated two-speed blower and a resistance heater arranged to produce a high speed jet of unheated air or a slower stream of heated air through a discharge nozzle shiftably mounted on the other end of the housing and movable between first and second positions. The housing includes a lateral air outlet in a side wall between the heater and nozzle. The nozzle includes as a unitary one-piece structure therewith valve members within the housing and nozzle and cooperatively associated with the housing other end and the lateral air outlet to inversely open and close the lateral outlet and housing other end in response to shifting of the nozzle to its first and second positions, respectively, to permit air to be selectively discharged from either the nozzle or lateral air outlet.

Abstract: An attachment tool for a vacuum cleaner hose is disclosed taking the form of an elongated flattened tubular housing; one end being adapted to connect to a vacuum cleaner hose, and the other end terminating in a flattened air intake opening. One flat face of the housing has an elongated opening therein adjacent the other end of the housing; the elongated opening having a means for selectively covering it. A pair of elongated strip brushes extend along opposite sides of the elongated opening.

Abstract: A vacuum cleaner is provided with holding devices on the sidewalls of its housing on which brushes can be mounted which enable baseboards in a room to be dusted while the vacuum cleaner is being moved about to clean the carpet.

Abstract: A nozzle for a vacuum cleaner which has an elongated comb-shaped part that can be rotated from a retracted position within the nozzle housing to another position in which it is extended out of the housing for use with a deep pile rug. The comb-shaped part has a cylindrical surface which moves adjacent to the suction channel and has an opening therein for communication between the comb-shaped part and the suction channel when said part is in its fully extended position.

Abstract: A ported brush supporting vacuum cleaner accessory capable of being removably mounted on the free end of a pliable hose in which a negative pressure is maintained. The brushes of the accessory are mounted on resilient tabs that normally close a number of spaced ports formed in the accessory. The brushes serve a two-fold purpose; first, when brought into rubbing contact with a surface they tend to dislodge dirt and dust therefrom, and second, the pressure contact of a brush with the surface results in the tab with which the brush is associated being temporarily moved to a second position. A tab when in a second position allows a stream of air at high velocity to flow through the port with which it is associated from the ambient atmosphere to the interior of the accessory. Each such streams of air carries dirt or dust dislodged from the surface into the interior of the accessory.

Abstract: A suction cleaner nozzle has main and edge cleaning secondary nozzle openings oriented at right angles to one another. An auxiliary passage connects the secondary nozzle with a zone of high suction in the suction source for the main nozzle. Valve means in the auxiliary passage may be moved selectively to open or closed position. A clean-out door is provided for the auxiliary passage.

Abstract: Suction pressure is applied to a desirable location by a valve assembly having a flat gate element elastically deformed by a selectively controlled cam actuator to unblock a flow passage between inlet and manifold portions of the valve body. A sealing gasket is peripherally mounted on the manifold portion in enclosing relation to an area larger than the flow area of the inlet portion. A vent passage to the manifold portion is unblocked when the gate element is closed, to re-pressurize the manifold chamber.

Abstract: A suction nozzle device for a cleanser foam suction apparatus or a vacuum cleaner. The suction nozzle device comprises an intake and a suction duct. The intake has therein a guide wall means completely partitioning the hollow space of the intake into a plurality of flow passages. The guide wall means projects at its leading edge substantially beyond the lower end of the peripheral wall of the intake so as to leave one of the flow passages open to the atomosphere when the suction nozzle device is placed on a surface to be treated. The suction duct extends from the intake, and has a throttle portion formed just behind the trailing edge of the guide wall means and a diffuser succeeding the throttle portion so as to cause ejection effect at the throttle portion by the jet flow of air, which the air enters from one of the flow passages open to the atmosphere.

Abstract: A wheeled suction nozzle is provided having, generally, a simplified three-piece construction including an upper shell, an intermediate plate and a bottom pan, with the intermediate plate sandwiched between the other two members so that its top surface and the bottom surface of the upper shell form the suction passageways for the nozzle.A rotary valve is included to activate edge or normal suction, with this valve rotating on a vertical axis and snapfit into position and thus not requiring any sort of connecting means which would positively maintain the rotary valve attached to the nozzle.

Abstract: A vacuum cleaner having edge cleaning features comprising a cleaner body with a floor contacting suction chamber and a suction duct leading from the chamber, an edge auxiliary cleaning chamber at one end of the suction chamber and communicating through a port with the suction duct, a valve within the cleaner body movable between open and duct restricting positions for selective full nozzle cleaning and edge cleaning with suction through the auxiliary cleaning chamber when the valve is open and operating means accessible from the exterior of the cleaner for the moving of the valve between said positions.

Abstract: A vacuum cleaner suction tool including a nozzle provided with improved structure for selectively applying high suction to an edge portion of the nozzle such as for improved cleaning of corner and edge areas. The suction control includes a valve adjacent the suction outlet of the nozzle and an operator for selectively positioning the valve to provide selective control of the suction action in the nozzle.

Abstract: A suction tool for use in a vacuum cleaner including a nozzle defining a suction inlet including a mid-portion and an edge portion and structure for selective blocking of air flow through the mid-portion to provide selectively high suction force at the edge portion.
