  • Patent number: 4304025
    Abstract: A handle for a roller applicator. The handle is of heavy rod stock which, for the purpose of this invention, is substantially rigid. The rod is bent so that the roller may be operated with the axis of the roller vertical at locations above or below the locations which may ordinarily be painted with horizontal strokes by a person standing on the floor or ground. The longitudinal axis of the grip portion of the handle is skewed to the rotational axis of the roller at an angle in the order of 30.degree. and the common perpendicular between the two axes is longer than two inches and the point of intersection between the common perpendicular and the axis of rotation of the roller is near to the point where the handle enters the roller.
