  • Patent number: 6808667
    Abstract: A contoured wall and method is disclosed for creating the contour and appearance of a wall formed from individual assembled units such as stones. The wall is formed from a plurality of mating form liners each having a reciprocal contoured surface to that of the desired stone wall. The wall is formed from hardenable construction material such as concrete poured between two mold members with the form liners attached to at least one of the mold members. Each of the form liners has a lateral relief mold face adapted to provide a molded surface having the contour of a stone wall. Each lateral relief mold face of the form liners has a latticework non-linear mortar-forming interlocking portion surrounding stone-forming recessed portions. The form liners are positionable in a plurality of arrangements wherein the interlocking portions and recessed portions along the mating edge of each form liner mate along mating edge of the adjacent form liner to form a continuous lateral relief mold face.

  • Patent number: 6234745
    Abstract: A conveyor and transfer apparatus for transferring containers seriatim from a substantially vertical stack of containers includes an endless belt conveyor pivotally mounted on a frame for movement between elevated and declined positions by opposed hydraulic actuators. The conveyor includes a frame for supporting a carriage thereon for movement along guide tracks forming part of the carriage support frame between a position wherein opposed container gripping arms may be actuated to grip a container and a position for depositing the container on a conveyor belt. A hydraulic linear actuator moves the carriage between its working positions and opposed gripper arms are actuated by respective cylinder and piston type actuators to move between container gripping and release positions.

  • Patent number: 5536557
    Abstract: Systems and methods are provided to contour hardenable construction material to resemble a natural stone wall. Form liners are provided which each create at least a single stone portion on the resulting wall. A plurality of form liners are matable with each other and are further securable to a form to create a first mold member for forming the wall. The form liners include a first surface portion for contouring the hardenable construction material to resemble a stone. The form liners further include a second surface portion surrounding the first surface portion for creating mortar regions on the resulting wall.

  • Patent number: 5386963
    Abstract: A form liner, for use in forming a wall having a natural stone wall contour from hardenable construction material, includes a first non-linear mating edge and a lateral relief mode face. The lateral relief mode face includes a plurality of interlocking contoured relief portions adapted to provide the natural stone wall contour. The interlocking contoured relief portions include first portions for forming interlocking contoured mortar regions and second portions for forming non-planar stone regions. A plurality of liners may be mounted adjacent one another to form a gang form liner wherein the non-linear mating edges of adjacent form liners are mated to form a continuous molding surface.
