EDGAR I]. CULVER, 03 AUSTIN, TEXAS.

FUEL.

No Drawing.

To aZZ whom it may concern:

, Be it known that I, EDGAR LpCULVER, a .hitizen of the United States, residihg at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Fuel, of which the following is a specification.

. My invention relates to an improved fuel and method of manufacturing same from Waste material.

The object is not only to produce an 1m' proved fuel, but also to utilize the waste or trash of a. community, factories, packinghouses, saw-mills, house garbage, solids 'rom sewerage, and garbage of Whatever description.

The non-combustible matter, such as cans, iron, glass, stones, and dirt are separated, and the remaining mass is placed in a pulverizer or reduction machine, Where it is ground and reduced to suitable size- It is then conveyed to a pug-mill or other ap proved mechanism for reducing it to a pulp, Water and steainbeing added so that the mass thus treated becomes a binder sufficient to bind the other ingredients, such as coal or coal-dust which may be added, all together, and the more of a pulp that this mass becomes, the more of the coal or coal dust it will bind solidly together. From the pug-mill or pulping machine, the mass is preferably fed to a mixer, although the mixing might be done right in the pug-mill or pulping machine. It is then that the fine coal or coal-dust in suitable proportionsif used-is added. The proportion is deter mined by the class of fuel required. F or instance, if a quick fire is required, less coal dust is used; and at this time might be added, if desired, a small percentage of crude oil, asphaltum or waste pitch from an oil refinery for the purpose of increasing the combustion, and any of the numerous common disinfectants in sufiicient amount to kill any infectious germ life is also added; also some of the numerous and Well-known deodorizing agents, preferably coalor Water-tar may be added, for the reason that the tar is an additional factor in the deo dorizing of the smoke While the fuel is being consumed. The entire mass, including these ingredients, is then thoroughly mixed, the mixture being reduced to the consistency of that of stiff mud brick material before being molded. The mass is then conveyed to a Specification of Letters Patent.

molding machine Where it is molded into the desired shapes and sizes, and from this molding machine is conveyed to a shed, kiln, or into the open to dry, somewhat as bricks or lumber are dried.

The mass can be conveyed, if desired, from the mixer or pug-mill direct to a drying-room or kiln, and When sufficient moisture shall have been removed, it is conveyed direct to a power-press Where the mass is pressed into desired shapes and size, and in any case when the composition is dry, it is ready for consumption and storage, and forms an excellent fuel for domestic or other purposes, having the heat units of value of most of the lump coal mined, and it possesses the added. advantagethat it will not deteriorate, or slack to any great extent, regardless of how long in storage, and it does not absorb moisture more than common firewood.

The .fuel is Wholly consumed, leaving practically no clinker-s, and very little smoke. and soot.

Thusdt will be seen that the fuel is manufacture from practically What is now a waste product, and that part which is now considered garbage is not only.- a waste but an expense for its disposal, and atpr e sent a menace to health, and unsanitary.

The invention, therefore, consists in a product composed of certain Waste elements,

such as garbage, trash, paper, manure, and all materials of a fibrous nature, mixed with hot water or steam, or both, into a binding pulp, to which may be added. tar during the pulping of the mass, the steam and tar acting to kill all germ-life, and the tar serving as a deodorizer for the manufactured product, as well as deodorizing thegfumes while combustion takes place. Th pulp thus formed is conveyed to a pug-mill Where the coal (if used) is added, after having been reduced to a dust, and the mass is thoroughly mixed, and then molded and dried.

The pulp formedis somewhat in. the nature of that used in the manufacture of pasteboard, and constitutes an excellent binder.

I claim:

1. The herein-described method of manufacturing fuel, which consists informing a binder from a pulp of city refuse, all of which is ground fine and mixed in the presence of liquid heated to a sufficiently high degree to kill germ life therein, and adding a deodolfting agent, which is connningg led degree to kill germ life therein, adding a with the pulp forming a. binder, after which deodorizing agent, which is eonnningled 10 the whole mass is dried. with the pulp forming a binder, then adding 2. The herein-described method of manucarbonaceous material, after which they 5 facturing fuel, which consists in forming a Whole mass is dried.

binder from a pulp of city refuse, all of Intestimony whereof I aflix my signa- Which is ground fine and mixed in the presture. ence of liquid heated to a sufficiently high EDGAR L. CULVER.
