Abstract:
1. An apparatus for dressing a masonry block having an externally viewable, non-load-bearing surface with a central area, a first marginal area and a second marginal area, with the first and second marginal areas adjacent the central area, the apparatus comprising: a support having a top, a front, a rear and a side edge, with the top configured to carry a masonry block positioned thereon; and a rotatable chipper, the chipper having a body with a rotational axis and a plurality of teeth rigidly attached to and extending radially outwardly from the body, with the chipper oriented so that the rotational axis of the body is generally parallel with the side edge of the support, with the plurality of teeth being unevenly spaced and randomly disposed about the body, and with the plurality of teeth configured and oriented to percussively engage and work only the first marginal area and not the central area of the externally viewable surface of the masonry block when the side edge of the support, with the masonry block positioned thereon, is moved from a position remote from the plurality of teeth to a position adjacent the plurality of teeth such that the plurality of teeth are able to randomly impact and fracture the first marginal area to form an erose surface in the first marginal area of the masonry block.
