  • Patent number: 10640997
    Abstract: A motorized floor stripper machine includes a motor, a frame, and a blade carrier. The blade carrier is capable of holding blades of different sizes, which can be installed on the blade carrier. The blade carrier is mounted to the frame on shock absorbers. A cam on the frame is connected to the blade carrier by a linkage that includes a bearing block, a pivot plate, a pivot pin, and a support plate. The blade carrier includes ball bearings that fit within linear channels mounted to the frame, so that when the cam is driven in an orbital motion, the blade carrier moves in a generally linear forward-backward motion. The blade carrier is relieved and includes multiple sets of holes for securing blades of different sizes.
