ABSTRACT:
A machine for pressing earth into blocks has a rectangular breech and a press foot vertically reciprocally drivable in the breech. A bucking block is horizontally reciprocally drivable into and out of registration with an open upper end of the breech. Portions of the upper surface of the bucking block are tapered upwardly from front to rear and a horizontal bucking bar extends across the breech and bears downwardly against the tapered upper portions of the bucking block when the bucking block is in registration with the breech. The bucking bar can be supported at selectively variable levels above the breech and assures a firm positioning of the block against the force of the earth being compacted by the press foot. A rod extending vertically from and movable with the press foot cooperates with a sight line device fixed to the machine to facilitate visual determination of the elevation of the press foot within the breech. This facilitates resetting the lowermost level of the press foot so that blocks of constant depth and density can be made regardless of the composition of the earth used. A neoprene pad on the press foot minimizes adhesion between the press foot and the earth pressed thereby, thus reducing the possibility of crumbling or disintegration of the block as the block is slid off the press foot.
