Abstract
Abstract An anchor for securing stone plates to a wall comprises a holder, which is adapted to be bolted to the wall, and an adjustable carrier, which is supported by the holder and has a protruding free end portion, which receives a mandrel that is adapted to be received in bores opening in the edge faces of the stone plates. In order to provide an anchor which is structurally simple and rugged, can carry a high load and yet be exactly adjusted, and can be handled in a particularly convenient manner, the holder comprises a base plate, which is adapted to be secured to the wall, and two juxtaposed fixing legs, which protrude from the base plate, the carrier consists of a tongue plate, which is sandwiched between the fixing legs and is adapted to be fixed in position by means of a clamp screw, which extends through a slot extending in the tongue plate in the longitudinal direction of the legs, said fixing legs have end portions diverging toward their free ends, and the tongue plate is slidably supported by a crosspiece plate, by which free end portions of the fixing legs are interconnected.

Claim 1
Independent Claim
247 words
In an anchor for securing stone plates to a wall, comprising a holder, fixing means for fixing said holder to a wall disposed on one side of said holder, a carrier, which is adjustably supported by said holder and extends from said holder on the opposite side thereof and has a free end portion remote from said holder, and a mandrel carried by said carrier at said free end portion and adapted to be inserted into bores formed in adjacent edge faces of said stone plates, the improvement residing in that said holder comprises a base plate provided with said fixing means and two transversely spaced apart fixing legs protruding from said base plate on said opposite side and having free end portions which are remote from said base plate and diverge toward their free ends, said legs also having parallel portions extending between said free end portions and said base plate and formed with coaxial holes, and a crosspiece plate connecting said free end portions said carrier comprises a tongue plate, which is sandwiched between said parallel portions and clear of both said free end portions and has two mutually opposite side edges, one of which is in sliding contact with said crosspiece plate, said tongue being formed with a slot extending parallel to said parallel portions and transversely aligned with said coaxial holes, and a clamp screw extending through said coaxial holes and said slot and adapted to fix said tongue to said fixing legs.
