Definitions

  • This invention relates to the manufacture of sheets, tiles, and the like applicable forbuilding and other similar purposes, which are made from plastic cementitious mixtures or materials such as asbestos and cement, or from a cementitious mixture in which the asbestos is the principal constituent by bulk or volume.
  • the invention can also be adapted to the manufacture or production of articles or prodnets of other shape or configuration from such materials.
  • the present improvements appe'rtain to an apparatus in which such a slab, tablelor mould is employed. and have for one object to combine therewith heating means which will facilitate the process of manufacture by ensuring a quicker drying of the material after it has been spread or applied to the surface of the slab, table or mould.
  • a further object is to construct the apparatus in such a way that/the slab, etcetera, can be used practically continuously, by utilizing both sides thereof, and to that end providing means whereby it can be readily inverted.
  • a still further object is to construct and arrange the various arts of the apparatus to simplisy and faci itate production and thereby r uce the cost of manufacture of the sheets, aid" thereof.
  • Fig. 1 is a part-sectionalside elevation of the apparatus designed for use in the production oi sheets.
  • Fig. 3 is a plan view, drawn to a reducedscale, of the carrier and support for retaining the sheet on the slab orthe like while the latter is being inverted, and for subsequently removing it therefrom.
  • thenumeral 1 denotes the slab, table or mould which is made of plaster of Paris, or other similar material or mixture of high absorptive capacity for water.
  • the slab, etc etera, 1 is made of appropriate dimensions and is carried in a metal framework shown comprising thetwo rectangular angle iron frames 2, 3, the ends of which are each connected by means of a;
  • a pipe 15, shaped into the form of a flattened coil or a double zig-zag structure is embedded therein, and one end, 16, of the pipe 15, 0 us into the one hollow trunnion 9, whilst t e other, 17 opens into the other hollow trunnion 10.
  • the ends 16, 17, of the pipe 15 may be fixed in the lates 5, 6, respectively, by the nuts 18, 19.
  • e hollow trunnion 9 may serve as the inlet to the flattened coil 15 and the other hollow trunnion 10 serve as the outlet.
  • the steam or hot fluid supply pipe 20 passes throu h a stufl'e ing box and gland 21 into the be low trunmon 9; 22 being a nut for preventing witha sheet of paper 39 or other suitable material which, while readily admitting of the pas-.
  • gland 24 being of the same construction as gland 21.
  • movable wedge-shaped rests or stops 25, 26, placed at opposite sides of the slab are provided. These rests 25, 26, are shown arranged in guides 2?, 28, fixed on the foundations 13, 14, at opposite sides of the bearings 11, 12. The rests or stops 25, 26, are withdrawn from their guides 27, 28, when it is desired to invert the slab, etcetera, 1, as hereinafter explained.
  • a loose removable metal frame is employed, which is made of a size and she e to correspond to thesheet, etcetera, to be formed upon the slab, etcetera, 1.
  • This frame is shown comprising two rigid side members 29, 30, and two thinner and flexible end members 31, 32, which members are shown connected together at the corners by 1 k means of plates 33 riveted to the members 29, 30, 31, 32.
  • small pieces 34 which are of the same thickness as the members 29, 30. 35 are the rivets fixing plates 33 to the various members 29, 30, 31, 32, 34 of the frame.
  • the size of the sheet, etcetera is equal to the area of the space enclosed between the inner edges of said members.
  • This construction of the frame facilitates the operation of removing the frame after the sheet, etcetera has been formed, and the subsequent-removal of the sheet from the slab or table.
  • the upper surface of the slab or tablel is.
  • the material from which the sheet is to be made is more or less roughly spread upon the surface of the paper 39, inside the frame, and it is then formed into an even layer or thickness by suitable means, as for example, by means of a suitab e heavy roller 40, comprising an outer metal pipe or tube filled with concrete or other suitable weighty material 41, and closed at the ends with cover plates 42.
  • the roller is provided with a central rod 43 which serves as a handle at each end projecting beyond the sides of the frame of the slab or table. The roller near its ends rests and rolls on the members 29, 30 of the frame.
  • the material After the material has 'been roughly spread on the slab or table, it is rolled level by moving the roller 40 backwards and forwards, any surplus material being thereby worked to the ends of the frame from which it can be removed in any suitable manner, as fomexample, by means of a trowel or the
  • the frame comprising the members 29, 30, 31, 32, is removed, and the separate or loose members 36, 37, are then taken away.
  • the formed sheet is now secured on the surface of the slab or table by means of a carrier and support sh0wn-see Figs. 1 and 3constructed of a suitable number of parallel members or slats 44 connected together. by a suitable number of other members 45 placed at right angles thereto.
  • Means are provided for attaching this support and carrier to the sides of the frame of the slab or table, and for this urpose each of said sides has hingedly attac ed to it an eyebolt 46, which are adapted to engage in the bifurcated ends 47, of the central parallel member 45; 48 are wing nuts on the ends of the eye olts 46 for clamping the carrier in position over the sheet.
  • the slab or table isv inverted the sheet lies upon the carrier and support so that the latter serves as a convenient vehicle for transporting it to any desired plaee.
  • the loosening of the wing nuts 48 allows the eyebolts 46 to be disengaged from the bifurcated ends 47 of the central parallel member 45, which permits the carrier, together with the sheet, to be lowered and removed.
  • the eyebolts 46 are pivotallymounted on g for fixing the carrier and support on either 39.
  • the paper 39 may be dip face of the slab or table.
  • heating means in the form of a flattened coil embedded in said table.
  • An apparatus of the nature indicated including a table of absorbent material, said table being adapted to be rotated in order to invert it, and removable rests for retaining the table in its horizontal or working position.
