Class 80.

WILHELM SONNET in FRANKFURT a. M. Machine for the production of bricks, cement goods and the like.

Patented in the German Empire on February 6, 1879. Longest duration: January 5, 1892.

The method I use to make bricks is that I do it did not knead dry clay flour with water, but only with hot steam bring the resulting plastic mass into contact while it is still warm in forms press and the shaped stones directly into the Bring oven.

The machine used in this process requires six horse powers and needs four men to service it (two men to bring the material, one man to put the material in the machine and one to set down the stones on the setter's cart, who brings the stones directly into the furnace) and delivers 15 bis 18,000 bricks a day. Their construction allows the production of stones with grooved ones Surfaces; Such stones facilitate the setting of the masonry and already offer when burning, the advantage is that the moisture can more easily escape, causing cracking the heated stones is effectively prevented.

The machine I invented is shown in the accompanying drawings.

It is Fig. Ι a side view of the machine.

Figure 2 is a top view of the machine.

Figure 5 is a front view of the machine.

Fig. 3 is a section through the hopper, the roller mill, the steam feed pipe, the Transport screw and mixer.

Fig. 4 View of the parts mentioned in Fig. 3 from above.

Like letters indicate like parts in the different figures.

ä is the hopper of the dry raw material;

b a rolling mill for grinding the raw material;

c the line with a mouthpiece which supplies the steam in such a way that the flour removed from the rollers by two diggers b 'and b ^{2 is} moistened over the entire width of the rollers;

d is a screw that mixes the steamed flour again and brings it to the filling pipe;

e is a worm that brings back the excess flour so that it does not fall on the machine;

f is a fill tube which widens downward and through which the material falls down into the molds;

g are eight double forms, g'g ² , without a bottom, which are arranged on a rotating table k;

0 is a crank ax with cranks h on both of them. End up; these cranks move two pistons k ^l and h ' ¹ up and down, h' ¹ is used to press the stones, while k ^l presses the pressed stones out of the molds; accordingly the crank of the piston h 'has a larger stroke than that of h ~ \

1 (Fig. 5) is an endless belt that runs over two rotating rollers and delivers the stones coming from the machine to the worker;

1 ° (Fig. 5) is a backing plate which serves as a base for the molds between the piston h ^{% and the filling funnel.} The plate V is attached to / under h * and rests on one end of a horizontal lever / ¹ Z ² , the other end of which is more or less heavily loaded, depending on whether the counter-holding plate exerts a greater or lesser counterpressure on the piston from above should exercise the pressed-down material.

On the axis ο sits the eccentric n °, the middle rod n ^l , axis » ² , crank m ³ , axis;» ² , crank ot ^{1 of} the rod m gives a swinging movement. With each oscillation, the pawl m ₀ attached to m engages in one of the eight cutouts of the table k and moves it by an eighth of a turn.

In order to make stones with grooved working surfaces, the lower surface of the prefabricated piston is divided into small squares by raised, intersecting ribs, while the counter-holding plate / ° carries a comb, which when moving the filled and pressed mold grooves the corresponding side of the stone.
