ABSTRACT:
A mold apparatus for forming concrete border stones has a unitary generally rectangular body with contiguous opposed longitudinal side walls, opposed outwardly curved end walls at each end thereof, an open bottom end, an apertured top wall, and an interior vertical wall extending transversely between the longitudinal side walls. The walls circumscribe generally rectangular longitudinally adjacent cavities for receiving concrete therein and generally rectangular openings in the top wall define generally rectangular longitudinally adjacent openings at an upper end of the cavities. An opening through a lower portion of the interior vertical wall joins the lower portion of adjacent ends of the cavities together. In a preferred embodiment the vertical wall is disposed closer to one end wall than the other to form a longer generally rectangular stone shape and a longitudinally adjacent shorter generally rectangular stone shape. A plurality of reinforcing ribs on the exterior of the mold prevent distortion and a plurality horizontally protruding tabs on the exterior facilitate manual manipulation of the mold. After removal of the mold there is a small gap between the adjacent stones except at their lower portions which are joined together by a short web of concrete filling the gap. The stones may be used in the adjacently joined condition or may be separated by removing the web of concrete, and may be positioned relative to one another to form various linear, curved, and circular stone border arrangements.
