- Another object of the invention is to providemeans for prolonging the combustion of briquettes.
- Another object of the invention is 'toprovide means for increasing the heat .units' or B. t. u.s of briquettes.
- Another object of the invention is to provide means for reducing the ash content of go briquettes.
- a further object of the invention is to provide means for causing more complete combustion in the burning of briquettes.
- a still further object of the invention is 5 to provide means for removing soot from the fire of the burning briquettes.

means for causing the ashes of briquettes to form a soft clinker instead of a fine powder, which is ver objectionable as it is carried 1Q by the air an deposited over the entire building in which the briquettes are being burned.
Another object of the invention is to providemeans for prolonging the combustion of briquettes.
Another object of the invention is 'toprovide means for increasing the heat .units' or B. t. u.s of briquettes.
Another object of the invention is to provide means for reducing the ash content of go briquettes.
A further object of the invention is to provide means for causing more complete combustion in the burning of briquettes.
A still further object of the invention is 5 to provide means for removing soot from the fire of the burning briquettes.
And a still further object of the invention is to provide a briquette having the above characteristics, which is of a simple so and inexpensive composition and which may be formed with the machinery now used for making briquettes.
With these endsin view, the invention embodies a briquette containing free burning as coal, coking coal, oil coke, borax, and a suitable binder, and if desired, nitrate may be used to reduce the amount of soot.
Although borax has been specified, it will be understood that any suitable fluxing ma- 40 terial such as clay, sulphur, lime or any combination or mixture of these materials or any similar material which may be adaptable to clinker or solidify to any degree the resultant ash from burning coal or which may reduce the volume of ash, or in any way the volume of ash.

change the consistency of the ash so that it will not spread or be carried by the air, may be used.
The ingredients may also be used with any fuel or material which is pulverized, mixed, and pressed into forms such as fuel briquettes where the resultant ash from burning the same is voluminous and light and may be taken up by the air.
In use the, ingredients are preferably mixed in the following proportions:
Per cent Free burning coal Cokin coal 14 Oil co e 9 Borax 1 Binder 6 These ingredients may also be used with mtrate for reducing the soot content in which case the proportions may be as follows:
Percent Freburning coal 70 Cokin coal 12 Oil co e 9 Borax 1 Nitrate 3 Binder 5 It will be understood, however, that the proportions of'these ingredients may be varied considerably and some of them may be omitted or others may be added without changing the characteristics of the product.
It will be appreciated that in the manufacture of briquettes from coal having a large quantity of ash, oil, or coke having a low ash content may be used in conjunction with a suitable fluxing material to still further lower The briquettes may be formed of substantially any coal which may be referred to as free burning coal, and any suitablecoln'ng coal may be used alone or in combination therewith. The oil coke referred to is the residue from o l or creosote refineries, or may be formed from the by-products of coal. The borax or sodium borate is a common product that is universally recognized.
Asphalt is commonly used as a binder,
however it will beappreciated that any suitable binding material may be used.
Where the nitrate is used, sodium nitrate is preferred, however, any suitable inexpenm sive nitrate or nitrite may be used.
It will be noted that these ingredients may bethoroughly mixed and formed by molds into hard cakes which may be used similar to lumps of coal, and any of the ingredients u may be omitted or may be used in difierent proportions as desired.
It will be noted that the foundation of this invention is in the use of borax or any other suitable fluxing material in a coal or g fuel briquettes, and the other ingredients such as the oil coke and nitrate may or may not be used, or may be used in different proportions as may be desired.
Having thus fully dscribed the invention what I claim as new and desire to secure by Letters Patent, is

of specified characteristics including coalescence of the ash where the characteristics of the materials in the fuel produce a pulverized ash in combustion, includin rate of combustion from comminuted car onaceous materials, including bonding ingredient which retards combustion, including chemical accelerator of combustion which comminutes the ash to a finer degree, that step which consists in introducing into the mixture including said carbonaceous materials including bonding ingredient and chemical accelerator, a fluxing agent in amount in definite proportion to the accelerator to compensate for the comminutin action thereof in relation to the ash and pro uce the specified coalescence of the ash substantially as described.
2. In the art of producing artificial fuels of specified characteristics including coalescence of the ash, where the characteristics of the ingredients of the fuel comminute the ash, from comminuted carbonaceous materials including bonding ingredient, that step which consists in introducing into the mixture including said carbonaceous materials inc1uding bonding ingredient, chemicalv fluxing agent in amount in definite proportion to the proportions of said carbonaceous materials including bonding ingredient to compensate for the comminuting action of said materials in combustion and produce a coalescent clinker forming ash.
