ABSTRACT:
BACKGROUND OF THE INVENTION
Forming adobe blocks by hand is a well known art. The material for the block is heavy textured clay soil. However previous apparatus have not had the power and the facility to produce uniform blocks in both density and dimension. Furthermore these are not suitable for high volume production.
Examples of previous known form of presses similar to the present invention are disclosed in U.S. Pat. Nos. 2,121; 143,806; 266,532; 348,617; 348,702; 435,171; 1,335,071.
SUMMARY OF THE INVENTION
The apparatus of this invention is mounted on a trailer chassis and may be towed to the site of construction.
The material used for the adobe is a heavy textured clay, preferably without any addition of moisture or binder material.
Preferably, the soil is compressed under high pressure and is so dense when ejected from the mould that the adobe block is instantly ready for use and need not be dried first. Since the machine produces uniform blocks dimensionally, it can be used to construct an adobe wall by dampening the upper course of the wall with water, and placing the next course directly on top of this course.
Because of the uniform size of the blocks there is no need to use mortar of any kind to bend the courses together. Preferably, the blocks are designed with a wedge shaped indentation on one face to prevent rocking of one on another when laid to form a wall.
The main objective of this invention is to provide an apparatus which will be capable of forming adobe blocks of uniform dimensions.
Another object of this invention is to provide an apparatus to form various dimensions of blocks by using interchangeable mould cavities.
Yet another object of this invention is to provide an apparatus for forming adobe blocks using readily available clay soil as the base material without the necessity of mixing binder and water with the soil, which is freshly dug before being placed in the apparatus.
A further object of this invention is to provide an apparatus which will be capable of forming adobe blocks in high quantities, and that these blocks can be used instantly without any drying time.
Another object of this invention is to provide an apparatus for forming adobe building blocks which will conform to conventional building practices, be of simple construction, economically feasible and relatively easy to operate.
Another object of the invention is to provide an apparatus that: (a) is self-contained as to everything needed to make adobe blocks, aparty from the actual clay; (b) can be taken, as a self-contained unit, to a building-site, and can be set up there with a minimum of skill and attention; (c) can produce blocks, under real building-site conditions, with a minimum of skill and effort on the part of the operator.
These together with other objects and features will become apparent and are contained in the description of details of the construction and operation as described and claimed hereinafter with references to the accompanying drawings.
