A lateral position of a cut guide is adjustable to regulate a thickness of the corner brick veneer. A height of the cut guide may also be substantially equal in length of the bring to be formed into the corner brick veneer. Once the cut guide and push block are mounted to the masonry saw, the brick is positioned within the corner jig and a first cut is made. The user's hands are out of the way so that the cut can be made safely without harming the operator. The brick is repositioned and a second cut is made in the brick to finish off the corner brick veneer. Once again, the user's hands are out of the way for safe operation of the masonry saw.

  • Patent number: 8028686
    Abstract: A thin veneer stone saw and related methods are provided. The thin veneer stone saw includes one or more circular saw blades. In an embodiment, two circular saw blades are arranged such that a masonry block, such as stone, may be sawed completely through in a single pass through the thin veneer stone saw. The stone may be delivered to, and processed through, the circular saw blades by a conveyor system. One of the circular saw blades may be centered below the top surface of the conveyor and protrude through a gap between two sections of the conveyor system. The other circular saw blade may be positioned entirely above the top surface of the conveyor system. The thin veneer stone saw may be operable to produce thin veneer stones in a variety of widths. The thin veneer stones may be used to form facade for a structure.

  • Patent number: 8011357
    Abstract: A cutting and dust collecting assembly comprises a rotatable, circular saw blade (4) having a first side (20), a second side (21), and a cover device (6) with a terminal member (52). The bottom surface (36) of the cover device extends in a plane. A longitudinal passage (45, 46) for the saw blade extends through the cover device from its top surface to its bottom surface. The terminal member comprises a terminal chamber (60) having an inlet (45a), the mouth of which coincides with the plane of said bottom surface. An outlet (58) can be connected to a vacuum source. The direction of rotation of the operating blade is such that the rear part (4a) of the saw blade which has passed beyond the bottom surface of the cover device will move in a direction upwards-rearwards towards the bottom surface. The invention also concerns the cover device, a sealing body belonging to the cover device and a working machine which is provided with the cutting and dust collecting assembly.

  • Patent number: 7954482
    Abstract: The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.
