A floor cleaning machine having a body carrying a separable rigid vacuum-retaining container, within said container, a flaccid container, means for lifting said containers as a unit from the body of the machine for disposing of spent and unspent liquids contained therein, cleaning the containers, and re-filling with fresh cleaning fluid. In a preferred embodiment, the machine is provided with a full floating squeege which enables the machine to be moved from carpeted surfaces to hard floor surfaces by the simple flip of a handle.

Wet and dry vacuum cleaner

A floor cleaner having a rigid vacuum-retaining outer case, which is adapted to serve as a liquid reservoir, a flaccid container within the case, means for creating vacuum within the case in and around the flaccid container including an inlet communicating with the case, means communicating with the liquid reservoir for discharging liquid on a surface to be cleaned, and means communicating with the flaccid container for drawing the liquid and included dirt from the surface to be cleaned into the container under the influence of vacuum whereby the flaccid container can fill and expand with used liquid at a volume rate essentially equal to the rate of depletion of the unused liquid, within the same space of the outer rigid reservoir.

A cleaning head assembly for a vacuum cleaning apparatus of the wet, dry and wet/dry types includes a rotatably driven brush carried within and laterally spanning the head assembly. A pair of floating vacuum heads are positioned on opposite sides of a housing for the brush, and each defines a portion of a vacuum pathway having an inlet opening adjacent to the surface to be cleaned, which extends from the inlet opening to a dirt collection zone within the vacuum cleaning apparatus. The floating vacuum heads are each attached to the brush housing in a manner permitting relative movement therebetween. In this regard, a track fixed to the brush housing engages a generally vertically extending flange extending from a vacuum head such that the flange moves within the track to control movement of the vacuum head relative to the brush housing. A roller spaces the flange from the track to minimize frictional contact therebetween, and a stop pin limits relative movement between the vacuum head and the track. A spring is provided to bias the vacuum head downwardly to place the inlet opening adjacent to the surface to be cleaned.

Head assembly for a vacuum cleaning apparatus having dual-individually

An emergency life saving vehicle (ELSV) for providing emergency services on a bridge independently of traffic conditions thereon. In particular, the ELSV conforms to the particular configuration of a bridge so as to ride along an otherwise unused portion of the bridge, and thereby circumvent any traffic which may have accumulated on the bridge. There are at least three different embodiments of the ELSV, each embodiment corresponding to a particular bridge structure. A first embodiment has a raised center portion so that the ELSV is able to straddle a lane dividing wall on a single span bridge; a second embodiment is adapted to straddle a space between two adjacent and parallel spans of a two span bridge by simultaneously riding on the interior walkways of each span; and a third embodiment rides along the interior walkways and retaining walls of a two span bridge. The ELSV can be controlled remotely and, among other things, carries emergency medical equipment, rescue equipment, and firefighting equipment to the scene of an incident on the bridge. In addition, the ELSV also carries cots for transporting injured victims of an incident, such as a personal injury automobile accident or a car fire.

Emergency life saving vehicle

A cleaning head assembly for a vacuum cleaning apparatus of the wet, dry and wet/dry types includes a rotatably driven brush carried within and laterally spanning the head assembly. A first vacuum chamber extends through the cleaning head assembly from a first inlet opening adjacent to a surface to be cleaned and laterally spanning the head assembly on one side of the brush, to a first exhaust port. A second vacuum chamber extends through the cleaning head assembly from a second inlet opening adjacent to the surface to be cleaned and laterally spanning the head assembly on a second, opposite, side of the brush relative to the first inlet opening, to a second exhaust port. A slidable gate valve selectively couples one end of a flexible hose to one of the exhaust ports for selective vacuuming of debris through either the first or the second inlet openings. The brush is automatically rotated in a direction which assists in propulsion of the vacuum cleaning apparatus across the surface to be cleaned so that the inlet opening through which debris is being sucked up, follows the brush. As the slidable gate valve is repositioned from one exhaust port to another, the direction of brush rotation is automatically changed.

Head assembly for a vacuum cleaning apparatus

A vacuum system having a closed air flow loop for cleaning rugs and floor or other surfaces. There is a vacuum source having a suction side and a controlled air flow pressure side (exhaust side). A head assembly is adapted to ride on the rug or floor or other surface to be cleaned. At least one rotatable brush is positioned within the head assembly. The suction side of the vacuum source communicates with the head assembly to provide suction within the head assembly for picking up dirt or other materials. The air exhaust side of the vacuum source communicates with the head assembly. A turbine motor is positioned so that the air exhaust from the vacuum source impinges on and drives the turbine motor. The brush and the turbine motor are interconnected whereby the turbine motor drives the brush. The means interconnecting is at a right angle to the axis of rotation of the brush. Peripheral air containment means associated with said head assembly are present to prevent air from entering or leaving around the periphery of the head assembly when it rides on the surface to be cleaned. The device may also have a closed loop for cleaning liquid to continuously recirculate.

Wet and/or dry vacuum cleaning unit

A physical shape-conformable, disposable, self-sustaining sound dampening unit adapted to attach to the air exhaust of a pair of electric motors to dampen the noise produced by the same, which comprises:

Low cost replaceable type sound dampening unit for vacuum cleaning

A scrubbing machine/vacuum cleaner which is carried by two spaced-apart front wheels and two spaced-apart rear wheels, having affixed to and extending from the front of the machine a cleaning head and brush assembly which is adapted to ride in proximity to, but in spaced-apart relationship from, the surface to be cleaned when all four wheels are resting on the surface to be cleaned. During actual cleaning operation, the head and brush assembly is adapted to press on the surface to be cleaned when the two rear wheels are raised from the surface to be cleaned. The front wheel assembly comprises a cross-member forming part of the frame carrying the machine, the cross-member having swivelably mounted thereto an axle. The axle carries the front wheels at its ends whereby the cleaning head is kept flat on the floor during the cleaning operation as the machine rolls over irregularities in the surface to be cleaned.

Scrubbing machine/vacuum cleaner

A portable air blower includes a flexibly resilient housing, a motor mounted within the housing, and a blower wheel fixed to a motor shaft. The motor is bolted at one end to a motor mounting bracket which, in turn, is attached to the housing by a plurality of first shock mounts. Each such first shock mount includes a bolt for connecting the motor mounting bracket with the housing, and a resilient elastomeric grommet interposed between the bolt and the bracket. A self-clinching nut fixes the bolt to the housing. The motor shaft rotates through a self-aligning bearing held by a pyramid-like support bracket which is attached to the housing by a plurality of second shock mounts. The second shock mounts are identical to the first shock mounts, and include a resilient elastomeric grommet interposed between the support bracket and the bolt.
