To all 1127mm it may concern:
Be it known that I, Fmnnmcu ()rro (i'ltill, a subject of the German Emperor, residing at .Afllmrsstrasse (3, Bremen, Germany. have invented a certain new. and useful Process for h'lamitacture ot' Briquets. of which the following is a specification.
The present invention has for its object. a process for the manufacture oi briquets from substances which will notbind under pressure alone, such as close-burning coals, ore, or coke. if means of a binding medium which becou'ics fluid when hot.
Tu briqueting substances of this kind, in order to economize as much as possible in the costly binding material, they have hitherto generally been heated either by di rect exposure to heat or by steam or the like and in some cases the briquets themselves lave been exposed to special treatment in .hot and cold chambers after they have been con'ipressed. All these methods are relatively costly because the heating of the whole of the material requires Yery considerable quantities of heat. On the other hand the pressure reservoirs and hot and cold chambers that are necessary for those known processes are relatively expensive owing to their large dimensions and the transportation of the material to and from the various places of treatment is also very onerous owing to the large quantities that have to be dealt with. A process has also been proposed in which the mass of fuel to be briqueied remains cold. This process, however, entails the employment of large quantities oi binding media which liquety under heat so that the process is unprofitable and ii'urthermore the employn'ient of hydraulic bind ng 1naterial is necessary to supplement th action of the iiquetying binding agent. 'l'hese hydraulic binding media constitute an undesirable addition because they increase the quantity of slag and ash and in point oi tact the large quantity of liquetying binding material necessary for this known process crts a prejudicial effect because in the fun nace the briquets retain their term with greater diiticulty in proportion they eon tain large quantities or resin, pitch or the like, because the high percentage of binding medium liquet'ying under heat causes a dis integration of the briquets at furnace or blast heat and the large generation of gas Specification of Letters Patent.

from the binding material when. heated also In accordance with the present invention the defects of the known processes are obviated in the following manner. In the fir t place the binding medium liquefying under heat is added to approximately three times thequantity of cokingcoal a quantity of water approximately equivalent to the binding medium. is distributed throughout the coking coal, thus constituting an auxiliary mass which is then employed as a combining medium for the close burning crude mass, by which means it is possible to manufacture briquets by cold pressing which con tain only about 4% of binding medium.
In. forming the auxiliary mass mately parts of coking; coal in a dry state are finely ground and then mixed with 20 parts of water at any desired temperature, cold water being Approximately 20 parts of binding medium liquefying under heat are then added to th resultant mass and the whole is carefully mixed. W hen the binding medium is added and the mixing effected the entire mass swells, the binding medium becoming extremely finely distributed throughout the mass as a whole. About 20% of the auxiliry mass thus constituted is then added. to the crude mass composed of the materials first mentioned, whereupon the briqueting takes place without. special heating the material under high pressure amounting to some 400 atmospheres. As the auxiliary mass contains only about 20% of binding material the total proportion of binding material contained in the finished briquet. is only about The binding material is suitably selected for the use to which the briquet is to be put. in the case of briquets for industrial purposes, when the smell is immaterial, the binding material may be pitch or pitch with admixtures of tar, naphtha and masut. For briqucts for household burning the binding material may consist of two parts of ordinary commercial resin and one part of mineral oil.
The auxiliary mass must not be manufac tured separately; at the contrary by suitably positioning and regulating the supply pipes or supply channels of the mixing ma,-

usually simplest andv chine in which the whole mass is mixed, it
may be attained that the auxiliary mass is continuously formed at the point Where the coking coal the Water and the binding material is introduced.
Briquets made according to this process are weatherproof in that they do not require to be coated with an insulating material, and they are also fireproof to the extent that they retain their form under the heat and blast of stoves. The binder is of such a character that there is no generation of gases which Would'cause the briquet to be destroyed at once. The binding agent employed is intimately mixed With the ass by I this auxiliary mass to the mass of material the method described of mixing the tinder While hot with the coking coal in the presence of Water. ing to this process are Weatherproof, as they contain nothing altectecl' by moisture, and by the use of the high pressure required by the binding agent used, the porosity of the briqiiets is very much diminished, if not wholly removed. The briquets also resist the action of the fire to a maximum degree, as they contain nothing developing vapor or The briquets made accordgases under the influence of the heat, a serious objection in processes of making briquets heretofore known.
What I'claim and desire to secure by Letters Patent of the United States is A process for making briquets from substances not binding under pressure alone, such as close-burning coal or coke) consisting in first mixing a quantity of the coking coal With Water, then adding a binding material liquefied under heat in the proportion approximately of four times the miX- ture of coking coal and Water and one part of the binding material, and then adding of which the briquets are to be made, and
then pressing the commingled masses into the form of briquets, substantially as described.
