  • Patent number: 4811450
    Abstract: A vacuum cleaner main cleaning chassis has a pair of suction air channels leading from a principal suction area thereof. Suction force is provided in common in the air channels with a single suction motor. One of the suction air channels is adapted to receive an auxiliary cleaning hose which diverts the suction force in such air channel into the auxiliary hose. During such auxiliary cleaning, increased suction force may be created in the auxiliary hose by closing off air flow in the other suction air channel, which relieves part of the load on the common suction motor. Such relief results in increased rotational speed of the motor, which in turn correspondingly increases the suction air flow in the air channel associated with the auxiliary hose.

  • Patent number: 4334337
    Abstract: The disclosure concerns a compact wet-dry vacuum cleaner adapted for collecting both wet and dry materials. The vacuum cleaner is powered by a by-pass type blow motor which is supported in a housing. The housing includes a baffle for separating the inflowing cooling air to the motor from the outflowing air which has cooled the motor. The placement of inlets and outlets to the motor housing prevents debris and liquid from splashing on the motor. A materials collection tank is separably attached to the motor housing to enable the tank to be removed for cleaning. The tank includes a nozzle at its front wall, which nozzle has an exit near the top of the tank. A curved air flow redirector at the top of the tank separates collected material from the air. The outlet from the tank is laterally spaced from the flow redirector. The motor housing is attached to a swivelable cover that extends over the motor. The cover extends over a duct that communicates between the materials collection tank and the blow motor.

  • Patent number: 4325163
    Abstract: A portable blower-vacuum unit has an impeller for drawing air axially through a housing air inlet, and for discharging the air centrifugally through a tangential housing air outlet. In a blower mode, a perforate cover plate prevents ingestion of solid material by the impeller. In a vacuum mode, a vacuum conduit connects to the housing in lieu of the cover plate, and a vacuum bag attaches to the air outlet. A mulching blade rotates with the impeller to chop any solid material passing through the housing when the unit is operated in the vacuum mode.

  • Patent number: 4225999
    Abstract: A multi-motor suction cleaner of the upright type having a power-driven rotary brush operated in the usual manner with a low-suction, high-volume airflow produced by a typical first motor-fan unit in the cleaner suction nozzle housing to carry out a usual floor, rug or carpet cleaning operation. The cleaner is converted to efficient off-the-floor cleaning merely by selectively uncovering an opening in a closed suction chamber carried by the cleaner containing a second motor-fan unit producing high-suction, low-volume airflow. A converter member mounted on one end of a typical flexible attachment hose is inserted in the uncovered opening. This automatically energizes the second motor-fan unit. The selective and alternate operation of the two motor-fan units provides a single cleaner that can carry out most efficiently every cleaning operation heretofore requiring both a canister and an upright cleaner to perform.

  • Patent number: 4096601
    Abstract: A cleaning apparatus for carpets, upholstery and the like in which a housing is displaceable along the surface to be cleaned and is provided with a motor-driven suction device, a foam-applying device and a pulsating scrubbing (massaging) device, the latter two devices being selectively operational apart from or together with a rotatable brush by control elements. The foam-applying (shampooing) device and the scrubbing device can be selectively coupled to the same motor as is used to drive the brush and the suction device.

  • Patent number: 3968938
    Abstract: A system is provided for handling debris, such as twigs, leaves, grass cuttings, refuse and the like comprising a fan-shredding device including a vacuum nozzle, the nozzle being shut off from the fan suction when various units are mounted thereon, such as a hopper and a flexible extension hose. Also, a blower is provided by similarly mounting a cowl on the nozzle and a blower tube on the discharge chute of the fan-shredding device. Shredded debris is bagged in a bag mounted on the discharge chute. On bagging, the shredded debris is compacted by the fan blowing action on the small shredded particles.

  • Patent number: RE47623
    Abstract: A vacuum cleaner having a base with a first air inlet, a rear housing, a removable handle and a socket on the housing to receive the handle. The handle has a grip, a second air inlet, and a hose connected to the second air inlet. The vacuum has a valve with a first inlet connected to the first air inlet, a second inlet connected to the flexible hose, a valve outlet connected to a vacuum fan, and a valve member that moves to connect the valve outlet to either inlet. The vacuum has a handle latch having one position in which it engages the removable handle to hold it in the socket and places the valve in one position, and a second position in which it releases the handle and places the valve member the other position.
