In the modern society, we can hardly imagine a world, or even a city without brikcks. Without bricks, no modern construction is possible, including long bridges above the rivers and skyscrapers high in the air. Human beings have used bricks for a long time. As I have mentioned in my previous posts, Chinese people used bricks to build the Great Wall as early as in the Ming Dynasty(around 13th century). At that time, however, bricks were made by hands and its productivity was very low. To meet the increasing need for bricks, people in industrial period invented the brick making machine. However, modern people are more and more dissatisfied with the speed of the traditional brick making machine. Fortunately, now we finally witness the appearance of a new type of brick making machine: the high speed automatic brick making machine.

As the name of the invention shows, the new ones are not only high-speed but also automatic. An automatic machine for pressing bricks at high speeds is provided with a pressure wheel and pressing tongues attached to the circumference of the wheel through an axle which permits the tongues to rotate or swing about the axle. Clay material is fed to an endless belt comprising a plurality of moulds, pressed by the pressure wheel, and then conveyed to a release station. The railing for the endless belt has an expanded portion so that the end walls of the moulds are released outwardly as they pass this portion, allowing the pressed brick to drop to another belt to be sent to an oven.

A high speed automatic brick making machine comprising:
(a) a pressure wheel having at its circumference brick pressing tongues said tongues being free to rotate and each being attached to said wheel by means of an axle passing through the tongue, the ends of the axle being fixed to the circumference of the pressure wheel;
(b) a plurality of moulds disposed on an endless belt, said moulds having a pair of side-walls and a pair of expandable end walls, said moulds corresponding to said press tongues the press tongues reducing the height of the material in the moulds by about one half, the railing for the endless belt having an expanded portion whereat the end walls expand to release the compressed brick contained within the mould after compression;
(c) a hopper for feeding clay to the moulds; and
(d) driving means for said pressure wheel and endless belt.a
