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.

Abstract: A vehicle shifter for use with a transmission is provided that is mountable on a transmission and can operate the transmission via an operating member held by a housing. The operating member may engage the transmission with a first end, and may be actuated by a user via a shift knob adapter at a second end. The operating member may be limited in its movement by a pin member, which is configured to engage the housing. The pin member may be urged towards a neutral position by opposingly positioned bias members. In some cases, the shift knob adapter may be offset from the second end of the operating member by a connector plate, and may be adjustable via splined connections. The splines may cooperate with the connector plate to allow the shift knob adapter to be maintained in a chosen rotational orientation.
