This invention relates to an earth block machine including opposed compaction chambers each receiving a reciprocal compacting member to form solid building blocks by compacting soil. The compacting members are reciprocated by a hydraulically actuated linkage mechanism connected to the compacting members to produce a very high compaction force while employing a relatively low hydraulic pressure.

Earth block or adobe building blocks have been used in the construction of various buildings for many years and continue to be an important building material. Original adobe block construction involved the positioning of a slurry material in a mold and letting it dry and cure for an extended period of time. Over the years, various machines have been provided for compacting soil into earth blocks which can be stacked as walls and floors for any kind of structure without the use of mortar or other type of binder material to lock the blocks together.

Block manufacturing plants are normally located in places where the prime raw material is abundant and easy to obtain. The blocks are then transported to the place of use, in many cases hundreds of miles. This invention eliminates the cost of transportation, thereby saving vast amounts of fuel by fabricating the blocks at the place of use. Thus, every building site becomes an instantaneous block factory.

Another object of the invention is to provide an earth block machine in accordance with the preceding object in which the hydraulic mechanism includes a pair of opposed generally aligned hydraulic piston and cylinder assemblies with the piston of each of the assemblies being connected to a pair of links which move the opposed compacting members in a reciprocal manner in relation to the compacting chambers.

Still another object of the invention is to provide an earth block machine in accordance with the preceding objects in which the inlets and outlets are opened and closed by sliding plates actuated by hydraulically powered piston and cylinder assemblies operated independently of the piston and cylinder assemblies for reciprocating the compacting members.
