  • Publication number: 20190054593
    Abstract: Disclosed is an invention that offers improvements to machines used for power floor buffing, grinding, and polishing including: a dust containment system which utilizes a single shroud with an attached lower brush to fully enclose the top and sides of a rotating implement whereas said shroud is spring loaded and allowed to move vertically and tilt in order to maintain firm contact with the floor at all times and prevent escaping air and dust; a dust extraction and collection system that expands upon said dust containment system by integrating a scroll shaped channel into the shroud and an outlet chute to extract and collect dust in a filtered dust bag and in which performance is increased by fins on the rotating implement driver and air inlet holes; a quick-release tool-less mechanism for attaching a rotating implement to the driveshaft with a hex shaped male/female interaction and push button release ball pin.

  • Patent number: 9765918
    Abstract: A gas powered internal combustion engine in which the gas is provided from the gas phase of a pressurized liquid gas in an liquified petroleum gas container and in which the liquified petroleum gas container is rigidly mounted adjacent to the internal combustion engine at a preselected angle to be in conductive heat transfer relationship to the internal combustion engine and in vibration receiving relationship to the internal combustion engine whereby the liquified gas in the liquified petroleum gas container is heated and vibrated and the effective surface area thereof is thereby increased. A pressure regulator is provided for receiving the gas from the liquified petroleum gas bottle regulating the pressure of the gas transmitted to the internal combustion engine and at least one flexible hose is connected to the pressure regulator for transmitting the gas therethrough.
