  • Patent number: 4499629
    Abstract: The assembly includes a shaft having its opposite ends threaded in opposite directions. This shaft is passed through a hole in a door to which door pulls are to be mounted. First and second door pulls have oppositely threaded openings for receiving the ends of the shaft. A finished disc member having a central aperture is on the shaft and includes a pin extending into a key way on the shaft so that the shaft can be rotated by rotating the disc to draw the pulls together and thereby sandwich the opening of the door between the pulls. A finished appearance thus results.
