Abstract: A machine having a rotatable and vertically movable table which includes four tile molds of four tiles each ninety degrees apart around the periphery of the table. A concrete source is provided at molding stations 180* apart while ejecting means are provided at oppositely disposed stations 180* apart. The table is rotated back and forth between the molding and ejecting stations. While two sets of tile, four each, are being formed two sets of tile, four each, are being ejected. The forming of the tile and the ejecting occur simultaneously as the table is raised and lowered relative to vertically stationary packer heads at the molding station and vertically stationary ejecting means at the ejecting station. A moisture sensitive probe automatically controls the concrete supply to provide the desired quantity of concrete at the molding stations.

Abstract: A concrete mold press for a concrete molding machine includes a reciprocating tamper operatively movable to an operative position in pressing contact with the concrete in a mold. The tamper includes a tamping plate mounted to vertically oscillate in response to the press head vibrations to repeatedly strike the press head to provide a tamping force which compacts the concrete in the mold.

Abstract: The method and apparatus for manufacturing concrete pipes, especially for lining shaft rings employs a form mantle and a form core with an annular space therebetween, a plunger, coupling means for temporarily connecting form mantle and core, and independent lifting means for the plunger and for the form mantle, the form mantle and core being coupled together and seated at a forming station, are then uncoupled prior to pouring concrete, then the concrete is poured and compacted and the mantle and core are coupled together again and are withdrawn from the formed work piece.
