Scraper adaptor for rotary buffer

US Patent No. 4821357 CA Patent No. 1255858

A removable adaptor for a power-operated rotary implement, comprises a circularly vibrating lower plate. When a blade is attached to this plate, an efficient scraper is provided for removal of adhered materials, such as old under-carpets. Past scrapers relying on longitudinal reciprocal motion have suffered from underpowering and jamming. These problems are avoided by the present invention.
