Definitions

  • This invention relates generally to structures that may be built using masonry blocks. More particularly, this invention relates to an apparatus for and method of dressing externally viewable surfaces of masonry blocks used to construct mortarless retaining walls.
  • Retaining walls are widely used in a variety of landscaping applications. Typically, they are used to maximize or create level areas and also to reduce erosion and slumping. They may also be used in a purely decorative manner.
  • retaining wall construction was labor intensive and often required the skills of trained tradespeople such as masons and carpenters. More recently, retaining wall construction has become significantly simplified with the introduction of self-aligning, modular molded blocks of concrete that may be stacked in vertical or offset courses without the use of mortar or any special skills. These blocks are available in a variety of shapes and sizes and a great many of them even allow a retaining wall to be curved or sinuous, so that it may be constructed circumjacent a tree, or parallel to a meandering pathway, for example.
  • Another approach is to take a molded block and place it in a rotatable container that tumbles it about (preferably, with other blocks or suitable material). This approach is much more cost effective and efficient that that of hand dressing each block. And, as with hand dressed blocks, each block so produced has a distinctive character. This approach, however, has a major drawback. The problem is that as a block is being tumbled, all of the exterior surfaces are being ground down. While this is a desirable result where the externally viewable surface of the block is concerned, it is an undesirable result for the remaining exterior surfaces of the block, particularly at the sides where the ability of adjacent blocks to be positioned flush against each other in a sealing relation may be compromised.
  • the flails comprise short sections of chain one end of which is affixed about the perimeter of a rotatable element, the other end of which is attached to a steel head.
  • the steel heads of the flails strike the entire front surface of a block as they are swung about by the rotatable element.
  • the flails produce acceptable results, there are several drawbacks.
  • a masonry block that, when assembled together with other masonry blocks to form a structure, creates the impression that craftsmen using hand tools constructed the structure.
  • a masonry block may have marginal areas of its externally viewable surface dressed and still be able to be combined with other masonry blocks to form joints that effectively prevent passage of particulate matter therebetween.
  • the present invention comprises an apparatus for working externally viewable surfaces of masonry blocks in such a manner so that they appear to have been hand dressed.
  • the term masonry block (or block) is intended to include any naturally occurring material, manmade material, molded cementatious block, natural and artificial stone or like material that may be used for buildings, indoor walls, partitions, facades, retaining walls, walkways, or other similar structures, with or without mortar.
  • the apparatus comprises a first station and a second station.
  • the first station includes a pair of cylindrically shaped, rotatable chippers with each chipper having a rotational axis and a plurality of outwardly extending teeth randomly disposed thereabout.
  • the chippers are adjustably arranged so that the rotational axes are parallel to and spaced apart from each other so that the outwardly extending teeth of the chippers do not interfere with each other during operation of the first station.
  • the first station also includes an adjustable block support that is positioned adjacent the chippers, preferably in an orthogonal relation relative to the rotational axes of the chippers.
  • the support is configured and arranged to permit constrained movement of a block towards and away from the rotatable chippers to enable opposing, marginal areas of the externally viewable surface of a block to be simultaneously worked.
  • the teeth of the chippers work or knap the opposing marginal areas of the externally viewable surface by percussively impacting and fracturing a block in a random manner. This produces an erose or jagged surface that is indicative of a rustic style block.
  • tooth and its plural form, teeth
  • marginal area includes not only the areas adjacent the periphery of the externally viewable surface of a block but also other marginal areas form, for example, at the intersection formed by facets in a block having a non-planar externally viewable surface.
  • the second station includes another pair of cylindrically shaped, rotatable chippers with each chipper having a rotational axis and a plurality of outwardly extending teeth randomly disposed thereabout.
  • the chippers in the second station are adjustably arranged so that the rotational axes are parallel to and spaced apart from each other so that the outwardly extending teeth of the chippers do not interfere with each other during operation.
  • the second station also includes an adjustable block support. As with the support at the first station, this support is positioned adjacent the chippers. However, instead of being positioned orthogonal to the rotational axes of the chippers as with the first station, this support is positioned so that it is collaterally aligned with and between the rotational axes of the chippers at the second station.
  • the support is configured and arranged to permit constrained movement of a block collaterally with respect to the rotational axes of the rotatable chippers to enable opposing, marginal areas of the externally viewable surface of a block to be simultaneously worked.
  • the teeth of the chippers work or knap the opposing marginal areas of the externally viewable surface by percussively impacting and fracturing a block in a random manner. This produces an erose or jagged surface that is indicative of a rustic style block.
  • the first and second stations it is possible to dress a plurality of marginal areas of an externally viewable surface of a masonry block in an efficient and expedient manner.
  • the apparatus may be used with a wide variety of preformed masonry blocks having a wide variety of sizes and surface textures. With the apparatus, it is possible to work a single or multiple areas of an exterior surface. For example, it is possible to work only the vertical margins of a block. Or, it is possible to work only the horizontal margins of a block. Or, it is even possible to work only one vertical margin and one horizontal margin. In that vein, it is envisioned that the apparatus may even work marginal areas that are not at the periphery of an externally viewable surface
  • the apparatus is used in conjunction with masonry blocks that have a split-face or roughened surface, so that the entire externally viewable surface of the dressed block appears rustic.
  • Another object of the present invention is to provide a method by which a masonry block may be dressed.
  • Yet another object of the invention is to form erose marginal areas that simulate hand dressing. It is another object of the present invention to increase the speed at which rustic masonry blocks may be fabricated by providing a plurality of chipper units.
  • a feature of the present invention is the use of chipper having a body with a rotational axis, about which a plurality of teeth are randomly disposed.
  • Another feature of the invention is that the components of the apparatus may be adjusted to provide different knapping depths, or to accommodate differently sized blocks.
  • An advantage of the present invention is that the randomly disposed teeth impact a marginal area being worked at a relatively slow speed.
  • Another advantage of the present invention is that formation of dust during the knapping process is minimized.
