Abstract A stripper device for use in removing a covering from a flat surface, such as tile from a floor. The device includes a elongated member or arm for pushing a blade over the surface, the arm having a connecting portion, for example, at an inner end for mounting on a fork-lift truck. At the outer end of the arm, there is provided a connector for the blade which is in the form of a disk having a sharp peripheral edge. The disk includes a mating connector, and preferable, the connectors of the blade and arm are in the form of a ball and socket combination so that the blade can rotate about a vertical axis, and the axis of rotation can vary relative to the arm so that the peripheral edge can lie flatly against the floor at all times. The disk has a convex upper surface which intersects a lower surface at a shallow angle relative to the horizontal plane containing the peripheral edge. The lower surface may have a central concave portion surrounded by a narrow annular portion which slopes up from the peripheral edge at an angle which is less steep than the shallow angle that the upper surface. The ball and socket structure forming the connection between the blade and the arm may be of the type which can be actuated to permit the socket to release the ball so that the device can be readily dismantled. The device is effective in removing a covering such as tile from a floor surface by pushing the arm across the floor so that a portion of the edge of the blade rotates under the edge of the covering. The device is of simpler construction than known floor strippers which have become complex, usually including a wheel carried frame mounting a motor driven rotating cutter or brush or oscillating blade.
