Definitions

  • This invention relates to rooting tiles and has for its object to provide an improved mold for Jforming valley tiles for use with the common forms of interlocking tiles and is particularly applicable to the forming of concrete valley tiles.
  • Fig. l represents an interlocking concrete valley tile to produce which is the object of the invention
  • Fig. 2 represents th-e frame for the pallet or mold on which the tile is produced
  • Fig. 3 represents the frame with the pallet in position
  • Fig. i represents the rear portion of the frame with the vertical members tilted over to give access to the underside of the pallet Afor removal of the latter with the molded tile upon it;
  • Fig. 5 represents the front portion of the frame with the hinged rib-forming mold in position.
  • the valley tile which has on each side two ribs a is shown in Fig. l and it is to be understood that the central vertical line in this figure represents the bottom of the valley; at one side a channeled projection Z) is provided while at the other side a ridge c with an underneath channel Z is provided.
  • the ordinary rectangular intermeshing tile with which the valley tiles match are provided at one edge with a rib c which iits over the channeled projection Z2, a similar channeled projection being provided on the other edge.
  • the mold :trame comprises a quadrilateral base e provided at the front with a hinged block m for forming the front portion of the tile and with side members or rails j, Ic between which the pallet '20 is placed and which l projects above the latter to an extent corresponding to the thickness of concrete required and thus act as striking-off gauges.
  • the pallet or mold p is of ridgedrform and ⁇ is provided with recesses B, C correspondingkv to the ribs to be formed on the valleytile.v
  • the peak of the pallet is supported upon an angular seat A carried on the member e, and the edges are supported on ledges, one, E, ot which is shown in Figs. 2 to 4.5
  • a hinged nib-forming mold Z is provided with a recessin corresponding to the nib to be formed on the underside of the front of the valley tile. It is to be understood that the pallet is of ridged formand that'the valley tile is molded upside down so that the nib has to project upwards from the tile as molded.
  • the mold Z is hinged at the side of the frame and normally occupies the raised position shown on Figs. 2 and 3 ofthe drawings.
  • Fig. 3 shows the parts inposition for the concrete to be molded.
  • the hinged member Z is, swung over to the position shown in Fig. 5 and concrete is tamped into the recess fn.; the member Z is then hinged back.
  • a striking rod x of rectangular section of which the end portions only are shown on Figs. l and 2 is driven into the concrete in the edge of the tile, this rod resting in a. notch 1 in the member f and against a ledge s on the front hinged blowck m; the rod is then slid out of the groove so formed.
  • the tile is now molded and now has to be lremoved on its pallet from the frame to a place where it hardens or cures.
  • thefront block m is tilted forward on its hinge F, and the rear strut 71 is folded back thus enabling the vertical F ig. 4 and permitting the operator to put his hand under the pallet and liftl it out.
  • a mold for forming interlocking valley tiles comprising a hinged frame and a ridged n pallet.
  • mold for forming interlocking valley tiles comprising a quadrilateral base member, rear hinged vertical members, a. front hinged block, and a. hinged nib-forming member.
  • a mold for forming interlocking valley tiles comprising a base member, rear hinged vertical members, an angular seat for the peak of a pallet carried by one of said Vertical members, ledges for the sides of the pallet carried by the'base member, a front hinged block, andI hinged nib-forming member.
