Definitions

  • An object of the invention is to provide bricks of this nature which shall have a high resistance to spelling and deterioration under the influence of heat.
  • Another object of the invention resides in the process of manufacturing such bricks.
  • the bricks are provided with means whereby they may be hung to form roofs, or held in place to form walls.
  • my invention contemplates a resilient openwork metallic structure which, during production of the brick, is partially collapsed to bring about the aforesaid distribution of said oxidizable elements throughout the brick material.
  • FIG. 1 shows a distended metallic framework which is used in the production of the brick
  • Fig. 2 is a side elevation of said framework
  • Fig. 3 is an end elevation thereof
  • Fig. 4 is atop view thereof showing the place at which a cavity is provided in the brick for hanging purposes;
  • Figs. 5 to 10 illustrate the manufacture of the completed brick; Fig. 5 showing the distended framework in a mould; Fig. 6 showing the same mould filled with damp sand; Fig. 7 showing the top plunger of the mould brought into alignment with the top surface of the mould; Fig. 8 showing the two plungers moving toward one another to compress the basic material and at the same time compress the framework; .Fig. 9 showing the top plunger elevated so as to clear the finished brick; and Fig. 10 showing the manner of ejecting the finished brick from the mould;
  • Fig. 11 is a cross-sectional view showing the general distribution of the reinforcing elements of the framework
  • Fig. 12 shows a completed brick in perspective
  • Fig. 13 shows the manner in which the oxidation of the framework elements provides a substantial union between them and the basic material.
  • a mould is used intowhich a compressible frame- .work is placed, which in one direction is preferably twice as large as the completed brick.
  • this framework is mounted in position in the mould on top of a lower plunger which is capable of being forced upwardly, the framework does not extend above the top surface of the mould.
  • the mould is then filled with damp sand of a basic character which. forms the refractory element of the ice completed brick.
  • the upper plunger is lowered and the lower plunger is raised, thereby compressing the loose basic material into roughly half of its original thickness and at the same time compressing the framework into position so that the elements of the framework are more or less uniformly distributed throughout the area of the brick.
  • the theory underlying the invention resides in the production of a. substantial plurality of elements running longitudinally of the brick which are made of oxidizable material, thus to provide a secure bond between them and the basic material.
  • Fig. l in which four elements such as the element 10 consist of a single strip of resilient material bent back and forth upon itself to be of a size approximately the size of the mould after the sand has been filled in and before compression. These elements it are welded to cross pieces 11-11 at the upper portion thereof, and l2-12 at the lower. They are also provided with fingers such as the fingers 13, the fingers 13 being adapted to sit upon the lower plunger when it is in its initial position in the mould. The upper fingers 13 are adapted to be engaged by the upper plunger as it comes down to compress the basic material and by engaging the fingers to also compress the elements of the framework.
  • Fig. l I show the framework as distended and in dotted lines, as at 14, show the amount of basic material originally introduced into the mould before com pression.
  • the upper plunger has a projection 26), which as the upper plunger is being lowered will form in one end I P 3 portion of the brick a socket 21, by virtue of which the brick is suspended or otherwise held in place in the wall or roof of a furnace.
  • The'upper plunger having been completely withdrawn and the lower plunger raised, as shown in Fig. 9, the finishedbrick is then moved forwardly or backwardly, thus to be ejected from'the mould.
  • Fig. 10, 1 show an end view of the finished brick on an enlarged scale, more clearly to show the distribution of the elements and also the hanging socket.
  • Fig.11 is a cross-sectional view more clearly indicating the distribution of the framework elements throughout the brick.
  • the invention merely contemplates that a plurality of such elements distributed throughout the area of the brick extend longitudinally thereof, whether they happen to be joined together as shown in this particular form or held in their initial position in some other manner.
  • initial position I refer to the positions of Fig. 5.
  • the number and distribution of the elements will depend upon the character of use to which the finished brick is applied.
  • Fig. 12 I show a perspective view of the finished brick and its socket portion.
  • Fig. 13 I indicate the effect of the oxidation of the elements, in that such oxidation extends into the basis material and forms a better bond than would be obtained by compression alone.
  • My improved brick may of course be used in connection with the customary metallic side and center plates.
  • My invention may also be used in connection with vibratory means should it be found necessary to do so to avoid voids in the deposited refractory material.
