Patent number: 3931662Abstract: A self-propelled machine includes a main housing supported on front and rear drive rollers and has an operator control handle extending from the rear. Front and rear elongated working brushes are driven in orbital movement in horizontal planes, with the front brush being positioned ahead of the front roller and the rear brush positioned behind the rear roller. A supply tank for the working solution includes agitating and aerating means for creating a foam dispensed from a pressurized tank through a flow control gate, and applied to the floor surface ahead of the front brush. The drive rollers act as squeegies. A collection system includes vacuum pickup nozzles adjacent each of the drive rollers for picking up material from the floor surface which is collected in a collection tank.Type: GrantFiled: August 20, 1973Date of Patent: January 13, 1976Inventors: James E.

Patent number: RE29247Abstract: A surface treating device such as a surface grinder in which power is transmitted to the operative elements of the assembly by a flowing gas, for example, air. The device is attached to a source of at least a partial vacuum, such as a vacuum cleaner. The motor fan unit of the vacuum cleaner together with a rotatable fan housed in the device form the power generating source which in turn operates the grinding member of the surface treating device in order to treat the work surface with an oscillating motion in a plane generally parallel thereto.Type: GrantFiled: May 5, 1976Date of Patent: June 7, 1977Assignee: Aktiebolaget ElectroluxInventors: Lars Gunnar Kilstrom, Goran Arvid Henning Ridderstrom
