  • Patent number: 4282668
    Abstract: A spring-biased easily located frame clip mounting system is disclosed for "frameless" picture mounting in which a U-shaped clip is slipped over a backing, picture and glass sandwich and is held in place by a spring attached to a plow-type anchoring device having teeth which are initially pushed through the backing at an angle, such that spring tension causes the plow teeth to dig into the backing to hold the plow anchor securely to and flat against the backing. The anchor in one embodiment is provided with an aperture and liquid adhesive is dripped through the aperture once the anchor is in place to permanently secure the anchor to the backing.
