Definitions

  • the present invention relates to a mortar-dressing device having a hollow section for applying, smoothing and floating of plastic materials, e.g. cementitious mortar.
  • the previous known devices of above type usually are constructed with a rectangular hollow section, which ordinarily has an intermediate ridgefor mechanical strength.
  • a disadvantage of mortar-dressing devices having flat parallel sides is that they are very diflicult for masons to handle.
  • the rectangular construction necessitates gripping holes which, in turn, disrupt the smoothing surfaces.
  • Another disadvantage of the above-mentioned rectangular-shaped hollow sections consists in non-existence of a sharp floating edge suitable for pressing plastic materials, mortar, into the corners of walls.
  • the known dressing devices of rectangular-shaped hollow sections are of substantial weight, especially when they incorporate for the reasons of mechanical reinforcement, an intermediate ridge which forms a hollow section having an internal wall.
  • the solution of the objects consists in providing the invention with a hollow section for applying, smoothing and floating of plastic material and having smoothing and/ or applying surfaces.
  • the working edge is formed by two acute angular smoothing surfaces running together and the walls are formed of lightweight materials.
  • the acute angular surfaces provide good gripping means for the masons, and eliminate, the need to provide additional perforations in the smoothing surfaces.
  • the sharp drawing edge allows mortar to be pressed into corners or joints and final floating of the mortar which was impossible with the previous rectangularly-shaped hollow sectioned tools.
  • One of the prefered embodiments of the invention is formed with a triangularly-shaped hollow section.
  • This shape provides an inexpensive and quick means of manufacturing the device, and has an extremely high resistance against longitudinal and vertical torsion.
  • the tool is formed wtih oblique gripping and smoothing surfaces.
  • a modified form of the invention has at least one convexly-shaped engaging and smoothing surface.
  • This convex shape also is characterized in having an extremely high resistance to longitudinal and vertical torsion. It provides both slightly curved smoothing surfaces and a sharp drawing edge.
  • the hollow section could be in the shape of a rectangular trapezoid.
  • a trapezoidal hollow section also provides a high resistance to torsion and can be easily and inexpensively manufactured.
  • the drawing edge is provided with a short radius of curvature to achieve a smooth flow of material at the smoothing edge.
  • Another form of the invention consists in making the hollow section of synthetic material, the acute angular portion being reinforced with a metal ridge.
  • the acute angular portion will always show a certain accumulation of material, which lends the required stiffness to the drawing edge. If it is desirable to increase the stiffness thus preventing warping, i.e., distortion of longer dressing rods, this can be accomplished by inserting of metallic portions into the interior of the hollow section. It is especially easy to do so, when the smoothing device is manufactured by extrusion molding. In that case a metallic pre-shaped rod will be extruded with synthetic material. It is best to choose from the plurality of the possible synthetic materials one which is abrasionresistant, stable and easy to handle, e.g., polyurethane. If the synthetic material shows suflicient strength, there is no need for reinforcement-portions and ribs of synthetic material can be provided.
  • there is at least one water level for levelling in the vertical and/ or the horizontal orientation of the tool which is positioned preferably at the middle of the longitudinal axis of the device.
  • this dressing rod eliminates the need for a separate air level. Moreover, half of the time previously required for dressing of the rough cast will be saved.
  • vertical and horizontal levels could be built in, i.e., the usual water or spirit filled levels containing an air-bubble. Yet it is possible, to use one level for both directions by providing a concave covering glass for a circular-shaped level with a cross graduation. It is understood that it is necessary to use only one level if the device is to be used only in one direction.
  • FIGURE 1 shows a perspective fragmentary view of the device according to the invention, having a triangular hollow section.
  • FIGURE 2 shows a modified version of the hollow section of FIGURE 1.
  • FIGURE 3 shows another modification of the device of FIGURE 1.
  • FIGURE 4 shows a device according to the invention with a trapezoidal hollow section.
  • FIGURE shows a device according to the invention with two levels.
  • the dressing device according to FIGURE l consists of thin-walled aluminum and three walls forming a hollow section; the engaging legs 1, 2 thereof forming smoothing surfaces 3, having convex shape.
  • the engaging smoothing surfaces 3 form an acute drawing edge 4, preferably having a short radius of curvature.
  • a device having relatively thin aluminum Walls will provide substantial resistance against torsion.
  • FIGURE 2 shows a modified version of the device, according to FIGURE 1, wherein only one smoothing surface 3 is of convex shape, while the smoothing surface 5 and the leg thereof are flat planar surfaces.
  • the device of FIGURE 3 has legs 1, 2 which are straight, while the drawing edge 4 is formed by the acute angular smoothing surfaces 5.
  • FIGURE 4 shows another modified version of the device according to the invention, having a thin-Walled aluminum hollow section shaped as a rectangular trapezoid.
  • the trapezoidal shape forms three smoothing surfaces 5, 8, 9.
  • the hollow section according to FIGURE 5 is also in the shape of a rectangular trapezoid.
  • the base 6 and leg 7 form two smothing surfaces 5, 8 which meet at the edge 4.
  • Opposite the base 6 lies a third smoothing surface 9.
  • the surface 9 are two circular perforations 10, to provide for the levels 11.
  • the upper of these levels 11 lies parallel to the longitudinal edges, thus parallel to the drawing edge 4, while the lower level 11 lies parallel to the transverse edge of base 6.
  • one dressing rod could be used for horizontal as well as vertical dressing.
  • While the preferred type of the invention combines an aluminum or light weight metal, it is possible to utilize extrusion type hollow sections, with or Without metal reinforcement ridges.
  • the features of this embodiment of the invention include a light weight hollow section having acute angular smoothing surfaces built in levels.
  • a dressing device of the character described comprising, an elongated hollow open-ended member having a pair of longitudinally extending walls and a connecting longitudinally extending back member supporting in spaced relation each of said walls along one longitudinal edge thereof, said walls meeting in an acute angle in a common longitudinally extending intersection portion to provide a longitudinally extending dressing edge, one of said walls being formed to provide a convex smoothing surface be tween said edge and back member, said walls being of substantially uniform cross-section over their length and being unsupported between said back member and intersecting portion to provide substantially uniform lateral flexibility of said walls between said back member and dressing edge, and said walls and back member terminating on planes substantially perpendicular to the longitudinal axis of said elongated member to define opposed open ends in said hollow member.
