ABSTRACT:
Fluid concrete is provided to apparatus which shapes the concrete into a desired form and may stack the finished products for removal by an operator. A concrete receiving portion of the apparatus holds the fluid concrete and discharges selected amounts thereof into a vertically open mold. The mold and the fluid concrete therein are supported during filling by a forming table. A compaction member is inserted into the mold to distribute and compact the fluid concrete therein, after which the mold may be removed from the table and held for vertical movememt by a mold carrier. Withdrawable support plates at the bottom of the mold support the shaped product therein after the mold has been removed from the forming table, with these support plates being selectively withdrawn to allow release of the shaped product from the bottom of the mold. A shaped product stacker is provided beneath the mold in position to receive shaped products released therefrom, and to stack a plurality of such products. A mode is provided wherein the concrete products may be shaped and stacked automatically.
