Blocks for constructing retaining walls
First Claim
1. A set of composite, masonry blocks for use in constructing a retaining wall, the set of blocks comprising:
- a wall block, generally in the shape of a trapezoidal solid, having a decorative front face, a rear face opposite and generally parallel to the front face, a top surface which is generally perpendicular to both the front face and the rear face, a bottom surface opposite and parallel to the top surface, and two side faces;
a ledge having first and second collinear, non-contiguous ledge portions extending downwardly from the bottom surface and across the rear face of the wall block;
further, the rear face of the wall block defining a key way, wherein the key way includes an aperture in the bottom surface of the wall block and a corresponding aperture in the rear face of the wall block, the apertures forming the key way being positioned between said first and second ledge portions;
an anchor block, in the shape of a rectangular solid, having a first end plate, a second end plate which is opposite to and generally parallel to the first end plate, two generally parallel side plates which extend between, and are generally perpendicular to, the end plates;
a central passage, defined by the end plates and the side plates, extending through the anchor block;
a key, complementary in size and shape to the key way in the wall block, extending outwardly from the first end plate, for cooperative engagement with the key way apertures of the wall block; and
further the second end plate defining a key slot which is complementary in size and shape to the key.

Abstract
The invention comprises a set of two composite masonry blocks, a wall block and an anchor block to construct retaining walls. The wall block is generally trapezoidal in shape and has: a decorative front face opposite and generally parallel to a rear face which defines a key way. The wall block has a top surface which is opposite and generally parallel to a bottom surface. The wall block has side faces which are not parallel so that the width of the rear face is shorter than the width of the front face. An alignment and locking ledge projects downward from the bottom surface and extends across the rear face. The anchor block comprises a first end plate which is opposite and generally parallel to a second end plate. Two parallel side plates extend between and are perpendicular to the first and second end plates. The side plates and the first and second end plates define a central passage. The first end plate further defines a key which is complementary in shape to the wall block key slot and the second end plate defines a key slot which is complementary in shape to the key. The anchor block is shorter in height than the wall block and the anchor block key is shorter in height than the wall block key way. Further, the anchor block may include a central plate, located between and positioned generally parallel to the end plates, extends between and is generally perpendicular to the side plates.
