  • Patent number: 5467501
    Abstract: An illuminated belt view for a vacuum cleaner wherein light is transmitted, via a light pipe, from a remote light source to an area directly underneath a transparent belt view window. The transparent belt view window is formed in the vacuum cleaner hood to allow the operator to observe the operating condition of the belt therein, the belt being operable to transfer rotational motion from a motor output shaft to a rotary brush. Illumination of the belt in the area of the belt view window allows the belt and the operating condition thereof to be observed during low ambient light conditions. Use of light from the light source, which is primarily a headlight, removes the need for an independent light source for the belt view window without significantly decreasing the amount of light which is transmitted to the area in front of the machine.

  • Patent number: 5465455
    Abstract: A wet and dry refuse vacuum apparatus is disclosed. A vacuum canister includes a vacuum motor, and inlet assembly, and exhaust assembly including a liquid pump, an inlet control assembly, and an operating electrical circuit. Upon activation, the vacuum motor sucks air and liquid refuse into the canister from the inlet assembly. As liquid fills the canister, the electrical circuit activates the liquid pump which pumps the liquid from the canister out through the exhaust assembly. In the event that the liquid enters the canister at a higher rate than it leaves the canister, the inlet control assembly raises with the water level in the canister to restrict the amount of liquid that may enter through the inlet assembly. A floatation ball is arranged to block a floatation orifice near the vacuum generating motor in order to prevent the liquid from contacting the vacuum generating motor in the event that the liquid level nears the capacity of the canister.

  • Patent number: 5455985
    Abstract: In a floor scrubbing machine, side squeegees for control of water on the floor are mounted with linkages that include vertical pivots so the squeegees can swing from side to side. They are interconnected with a tie rod so they swing in unison. A rear squeegee swings to one side or the other when the machine turns due to friction with the floor. A push-pull cable is connected between the rear squeegee mounting linkage and the linkage of a side squeegee to cause the side squeegees to swing or steer during turns. This positions them to effectively control water on the floor during a turn, and reduces squeegee wear. An alternative to steering them with the rear squeegee is to steer them with a hydraulic cylinder plumbed into the machine's power steering system.

  • Patent number: RE35033
    Abstract: This is an improvement for a powered floor scrubber which in use is moved forward and backward across a floor to be scrubbed. A scrub brush is rotated within a housing which is open at the bottom and water is supplied within the housing. The improvement consists of attaching double lipped suction squeegees at both the front and rear of the housing and connecting them both to a source of vacuum to suck up soiled water from the floor. The flexible squeegee lips are mounted in such a way that as the machine is moved forward the lips of the front squeegee fold together and shut off the airflow to it while the rear squeegee remains functional. When the machine is moved backward a reverse action of the squeegees occurs, so that there is always a functional squeegee sucking up soiled water behind the scrub brush while airflow to the opposite squeegee is shut off whether the machine is moving forward or backward.
