MANUFACTURE OF BUILDING-BLOCKS.

No Drawing.

To all whom it may concern:

Be it known that we, CONRAD Konrnmo and CARL JAENTSCH, both subjects of the German Emperor, and residents of 3 Hedwigstrasse and 37 Weibergstrasse, respectively, Cassel, Germany, have invented certain new and useful Improvements in the Manufacture of Building-Blocks, of which the following is a specification.

This invention relates to the manufacture of building blocks from peat.

Hitherto bricks have been made by reducing peat to a pulp or to fibers and adding agglutinants so as to form a moldable mass from which the bricks are molded, the wholebein closely united by pressure. Peat has also een rendered fit for many useful purposes by submitting it to a steeping process 1n compositions adapted to ren er it elastic and firgproof. It has also been pressed and dried and mixed with water-glass and then further com ressed so as to form a hard material out 0 which boxes can be made.

According to the resent invention, building blocks are ma e by impregnating unpressed pieces of peat with a solution of water-glass, and according to another phase of the invention, building blocks'are made from un ressed pieces of peat b coatin them with a layer of an sultable e-proo ing material, the centra ortion of the peat remaining unaltered. ater-glass may be employed to form this coating.

According to the first phase of the invention, the eat which is out directly out of the soil w1 on being pgessed added, is saturated, after being me W1 a so u -1on of waterlass and the pea 1s then allowed tom 6 51s solution of water-glass may vary. hus, soda water-glass, potash waterin either way any kind of mortar may be Specification of Letters Patent.

used, but a mixture of waterlass with a hydraulic material, such as Roman or Portor saturated with a solution of water-glass is effected.

A wall made of these bricks is a perfect substitute for any loam or plaster wall or wall formed of plaster of paris with reinforcing wire-work, and nails can be driven into it; and it has moreover the advantage of not conducting sound and of being a bad conductor of heat, as the brick remains porous. A further and very important advantage is that bricks thus impregnated are fireroof and are not destroyed even under the influence of the greatest heat. Such bricks are particularly suitable for outside walls of small one-storied buildings as they are not affected by the weather. But partition walls and floors or ceilings, and especially intermediate layers in ceilings and walls, can also be made with them very advantageously. They can likewise be used for making'building plates or slabs of a rather large size, as their weight is exceedingly small.

What we claim is l. A process of manufacturing building blocks, which comprises the impregnation of unpressed blocks of peat with a solution of water-glass.

2. A process of manufacturing buildin blocks, which comprises coating unpressed blocks of peat with a layer of water-glass, the central portion of the peat block remaining unaltered.

3. A building block consisting of an unpressed block of peat impregnated with water-glass.

4. A building block consisting of an unpressed block of peat provided with a coating of fire-proofing material, the central portion of the block remaining in its natural condition.

In testimony whereof we have hereunto signed our names this 22d day of March 1909, in the presence of two subscribing witnesses.
