Definitions

  • Contoured roofing tiles of this type are generally laid in overlapping relationship over roof surfaces having a certain angle of pitch.
  • this angle of pitch In recent years the tendency has been' for this angle of pitch to decrease partly because of external design considerations and also because by reducing thepitch angle the actual roof area is also reduced with corresponding saving in roofing materials.
  • each tile is provided with a bridge which forms'a barrier against the rain water.
  • the object of the present invention is to provide apparatus for use in applying the bridges to the tile during manufacture of the tile.
  • apparatus for applying bridging means to a contoured roofing title including:
  • a displaceable member having a chamber and (c) a plunger device comprising first and second plungers, said chamber being located, in one position of said member, directly below said aperture when said first plunger is operative to charge said chamber with material and, in another position of said member, being located directly below said secondplunger, said second plunger then being operative to discharge the material in said chamber onto the tile.
  • FIG. 1 shows a contoured roofing tile in section to which a bridge has been applied
  • FIG. 2 shows one form of apparatus for applying the bridge to the tile of FIG. 1.
  • the tile is made of a sand and cement mixture and is conveniently manufactured using an extrusion operation.
  • a continuous ribbon having the 3,606,652 Patented Sept. 21, 1971 required cross-sectional shape is extruded and tile forming lengths are severed from the ribbon.
  • the bridge is formed on each tile by pressing a bar 2 of the material from which the tile 1 itself is being made into the trough of the ribbon before the tile forming length is severed from the ribbon, the bar 2 being pressed into the ribbon by about 4; inch.
  • the apparatus for applying bridges to a continuous ribbon of extruded material comprises a hopper 14, which contains the sand and cement mixture, and two pneumatically operable plungers 1-5, 16.
  • J plungers-15, 16 are disposed on opposite sides respectively of the back plate 17 of the hopper 14 such that the plunger 15 is disposed inside the hopper 14 and the plunger 16 is disposed outside the hopper 14.
  • a slit shaped aperture 1'8 is provided at the base of the hopper 14, through which sand apd cement mixture may be discharged.
  • the hopper 14 is mounted on a frame comprising two spaced and parallel channel form members 19 along which a rectangular plate 20 may be slidably displaced, the channels in said members 19 serving as guide grooves for the slidable displacement of the plate 20.
  • the plate 20 has an aperture 21 and the dimensions of the aperture 21' correspond to the dimensions of the bridge to be formed.
  • Two screws 22 are provided'on the plate 20 for aligning the aperture 18 in the hopper 14 with the aperture21 inthe plate 20 for charging the aperture 21 and for aligning the aperture "21 with the plunger 16 for discharging the contents of the aperture 21 onto the continuous ribbon.
  • a base plate 23 is disposed beneath the aperture 18 in the hopper 14 and spaced therefrom to allow the plate 20 to be inserted between this plate 23 and the hopper 14.
  • This base plate 23 is contoured such that when the aperture 21 in the plate 20 is in a charging position beneath the hopper 14 it not only prevents sand and cement mixture being forced straight through the aperture 21 but also enables the base of a sand and cement mixture charge in the aperture .21 to be formed in the desired manner under pressure from the plunger 15.
  • An agitator 24 driven by a chain and sprocket arrangement 25 is disposed in the hopper 14. This agitator 24 serves to keep that part of the hopper 14 beneath the plunger 15 charged with sand and cement mixture.
  • the aperture 21 in the plate '20 is aligned with the aperture 18 in the hopper 14 and the plunger 15 is operated whereby the aperture 211 is charged with sand and cement mixture.
  • the mixture is pressed against the contoured base plate 23 and against the walls of the aperture such that the charge is formed in the desired shape.
  • the aperture 21 is subsequently aligned by means of the screws 22 with the plunger 16 and the plunger operated thus displacing; the charge in the aperture 21 onto the continuous ribbon of extruded material.
  • the apparatus is mounted for reciprocation and, during a discharging stroke of the plunger 16, moves with the ribbon of extruded material so that the bridge comprising the mixture charge in the aperture 21 is correctly pressed into the ribbon.
  • Apparatus for applying bridging means to a contoured roofing tile including:
  • a plunger device comprising first and second plungers, said first plunger being located in said hopper, said second plunger being located outside said hopper, said chamber being located, in one position of said member, directly below said aperture when said first plunger is operative to charge said chamber with material and, in another position of said member,
  • Apparatus according to claim 1 in which a base plate is provided spaced from the base of said hopper, said member, in said one position, being disposed between said hopper and said plate and said plate providing a base for said chamber to prevent material passing straight through said chamber during charging of said chamber.
  • Apparatus according to claim 5 in which screws are provided for aligning said member in said one or said other position by slidable displacement of said member along said channel form members.
