Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed January 12, 1905. Serial No. 240,703.

1'!) all wilt/fin, it 711/1151 concern:

-Be it known that I, Josnr KNors, master shoemaker, a subject of the King of Prussia, German Emperor, residing at No. 121 Pontstrasse, AiX-la-Chapelle, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Proc esses of ManufacturingArtificial Fuel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to i which it appertains to make and use the same.

My present invention relates to 'a process for manufacturing artificial fuel consisting substantially of an amorphous coal obtained from the peaty or turfysubstances of moors, bogs, or fens and of a flour won by boiling leather offal and grinding the resulting mass when dried. After both ingredients have been thoroughly mixed in the desired proportions they are simultaneously heated and pressed into suitably-shaped cakes or briquets.

To employ leather offal in form of chips as a binding means is not new in itself in the manufacture of artificial fuel; but then they Were used as such and particular pains were taken to retain the shape of the chips.

The peaty or turfy mass composing moors, bogs, or fens is in the first place boiled to remove all juice contained therein, after which the partly pulpy and partly granular mass obtained thereby is transformed in any suitable manner into amorphous coal by subjecting it to a glow heat.

To produce the leather flour employed as a binding means, leather offal is squashed,

l crushed, or otherwise preparatorily treated and then boiled, after which the pulpy mass thus obtained is dried and then reduced to a flour by grinding or any other suitable mechanical operation. The leather flouris then mixed with the amorphous coal in the desired proportion, and finally this mixture is brought into suitable forms, wherein it is simultaneously exposed to a glow heat and to pressure, whereby the particles of the leather flour are -mechanically binding the particles of the amorphous coal in such a manner that a transportable briquet is produced.

The artificial fuel thus obtained is burning with a strong flame and is lighter than the natural coal.

I I claim- The process for mamifacturing artificial fuel, consisting in boiling peaty substances to remove their juice, transforming the resulting mass into amorphous coal by exposing it to heat, boiling leather offal, drying the repowdery state, mixing the amorphous coal with the leather flour, and finally uniting both ingredients to transportable briquets by simultaneously subjecting them to heat and pressure.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
