Intelectual Properties

A scraper for removing material, adhered to a surface, in strips. The scraper has a front scraping edge and at least one cutting edge at one end of the scraping edge. The cutting edge extends generally transverse to the scraping edge.

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.

A powered tile breaker has an adjustable frame and the frame is further comprised of a handlebar member, a foldable shaft, a base member, and wheels. The base member holds a chiseling assembly which comprises a main electric motor located inside a motor casing. The motor powers a chisel member. The chiseling assembly is angularly adjustable by way of an actuator member which consists in a secondary electric motor driving a piston. The piston has one end rotationally connected to the base member, and the actuator member is rotationally connected to a lever member which extends from the chiseling assembly and which connects at a pivot point.
