COMPOSITION FUEL.

fPECIFICATION forming part of Letters Patent No. 784,302, dated March '7, 1905.

Application filed March 10, 1904:. Serial No. 197,472.

To rtZZ whom, it Duty concern.-

Be it known that I, CHARLns H. CARPEN- TER, a citizen of the United States, residing at South Bend, in the county of St. Joseph, in the 5 State of Indiana, have invented certain new and useful Improvements in Composition Fuels; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My present invention relates to improvements in artificial composition fuels specially designed for domestic heating and in the process for producing the same.

The primary object of my invention is to provide cleanly, sootless, and economical artificial fuel the ingredients of which are found in all parts of the country and can readily and conveniently be combined, possessing a very high degree of heating power and which is made up into small blocks in a form convenient to handle and use, is practically odorless in burning, produces no cinder-s, and leaves no clinkers.

Another object is to provide a composition fuel resembling anthracite coal in weight, appearance, and heating power and whose component elements are so united as to preserve and distribute the volatile elements throughout the mass, thereby conserving its heating units.

The novel features of my invention reside in the composition produced by the union of the component elements and in the process by which this fuel composition is produced.

My improved artificial fuel consists in the following ingredients combined in substantially the following proportions to each ton of the fuel: common peat or muck, nineteen hundred and fifty pounds, common salt, ten pounds, powdered rosin, forty pounds. The above ingredients are thoroughly mixed in any proper manner. The peat usually contains moisture, which is removed before mixing, leaving it properly dried, after which the composition is made up into any suitable form by subjecting it to a pressure by suitable means of approximately twenty-four thousand pounds to the square inch. The powdered rosin when properly distributed throughout the mass serves as an efiicient binder, and the ingredient of salt performs the function of eliminating the soot in burning.

My invention is preferably pressed into small blocks resembling in size those of eggeoal and stove-coal, though it may with equal facility bemade into blocks of any desired form or dimension. IV hen the composition is subjected to the intense pressure specified, the volatile matter of the peat which would otherwise escape and be lost is distributed throughout the mass and preserved, thereby materially increasing the firmness, cleanliness, and eificiency of the fuel.

My improved fuel thus produced resembles hard rubber in appearance and solidity and burns like anthracite coal, whose heating power it approximately equals, but burns without appreciable odor, makes neither sparks nor cinders, in combustion is cleanly, sanitary, and nearly smokeless, leaves no clinkers what ever, and has been proven by numerous practical tests to be superior in heating powerto soft or bituminous coal, and nearly, if not quite, equal to anthracite coal.

' This artificial fuel is of course equally Valuable for the generation of steam and for any and all purposes for which fuels are generally employed.

, The component elements of this fuel are everywhere cheap and abundant and can be manufactured from the materials at hand or conveniently accessible in any part of the country.

\Vhile the exact proportions of the above ingredients are not absolutely essential to the formation of my improved product, yet it is believed the best results are secured by substantially the proportions above specified, though I do not desire to be understood as limiting myself to the precise proportions described.

Having thus described my invention and the manner of employing the same, what I desire to secure by Letters Patent is 1. A composition for artificial fuel consisting of peat or muck, salt, and powdered rosin,

- in substantially the proportions specified, and

so compressed into a solid mass or compound as to distribute the volatile and resinous matter of the composition throughout the mass and retain the same.

2. An artificial fuel consisting of a hard compressed amorphous mass in which the easily volatile matter is retained by high pressure, and consisting of peat, salt and rosin mixed in substantially the proportions described, and compressed by high pressure.

3. The process of making artifical fuel consisting of mixing peat, salt and rosin in the proportions specified, and then compressing the same into a hard amorphous mass in which the easily volatile matter is retained by high pressure and distributed throughout the mass.

4:. The herein-described process of making artificial fuel Which consists of mixing peat, salt and rosin together, and then forming the same into hard amorphous masses by high,
