ABSTRACT:
A three station turret-type apparatus is provided with a first station including structure for receiving a quantity of soil to be compressed into a building block, a second station for compressing the soil into the desired building block and a third station for ejecting a formed building block from the apparatus. A rotary table is equipped with peripherally spaced sleeves for successive registry with the three station positions and each sleeve comprises a mold in which the desired block is to be formed. The sleeves are removable and replaceable and one form of sleeve is constructed to have an auxiliary smaller plan area sleeve removably mounted therein. Further in the second station position, a stationary bottom plate closes the lower end of the sleeve registered therewith and the bottom plate faced with a urethane elastomer material. A pressure head opposes and is movably toward and away from the stationary plate and is faced with a similar urethane elastomer material.
