Abstract: A rotating carrousel having four mould cavities equally spaced at ninety degrees from each other. The moulds are open vertically to the sky and in the opposite direction. The mould cavities are on the same pitch circle from the center of the axis. The rotary table is positively locked at each ninety degree turn. When the table is locked in position each station is in its position. The hopper containing pre-granulated soil is mounted stationary above the number one station. The hopper is fed by a screw conveyor from a hammer mill which breaks up the dug-out soil into a uniform granulate. This is most important for the manufacture of high quality adobe bricks. When the hopper has filled the mould cavity the carousel is turned ninety degrees and the filling process is repeated. At the same time the ram at number two station compresses the soil into a high density adobe block.
