  • Patent number: 4750226
    Abstract: A carpet laying tool is disclosed comprising an angular member connected at one end to a carpet wedging, rotatable circular wheel, and at the other end to a carpet compressing, swivelable block member. The tool is used to wedge the carpeting being laid into the juncture of walls and floors, while simultaneously pressing it onto carpeting tack strips or an adhesive, whichever is being used to retain the carpet in place. The tool is used by holding it by the angular member and placing it horizontally on the carpeting, adjacent and at a slight angle to a wall, so that the wheel and block are both in contact with the carpeting. A downward force is then applied in the direction of the angle of tool disposition, and the tool is moved along the juncture in the direction of the wheel, simultaneously forcing the carpeting into the area of the juncture, and onto the tack strip or adhesive.
