MEANS FOR BURNING STRAW, CORNSTALKS, 840..

SPECIFICATION forming part of Letters Patent No. 463,249, dated November 17, 1891.

Application filed August ll 1891. Serial No. 402,376. (No model- New York, State of New York, have invented certain new and useful Improvements in Means for Burning Straw, Cornstalks, and Such Like Fuel, of which the following is a specification.

As is well known in many sections of considerablearea in the United States and elsewhere, it is difficult, and at times impossible, to secure coal or wood for fuel, and even when it may be had its expense is such as to impose a heavy burden upon the consumer. Especially is this true with reference to farmers and other persons living at points removed from railroads, because in addition to the enhanced price of fuel the labor of transporting it from the railroad to the place of consumption is very great It is well known that in some localities fuel famines have at times been so severe and transportation facilities so deficient that farmers have been compelled to burn corn forcooking and heating purposes. This extraordinary condition has been brought about partly by scarcity of fuel and partly by the fact that the rates of transportation of farm products were so high that there was no profit to the farmer in sending them to market. On all farms where wheat, oats, barley, rye, or corn is grown there is produced in weight as much or more straw or stalks as grain. The cornstalks may be used only to a limited extent for fodder, the straw has only a restricted use, and the supplies both are always largely in excess of the demands to which they may be usefully or economically applied. In the absence of sufficient quantities of straw or cornstalks, to be utilized as presently described, there is always an ample supply of weeds, which may be mowed, permitted to dry, and accumulated in stacks. This material,whether straw, constalks, weeds, or similar vegetable growth in a dried condition, forms the fuel which I purpose burning in the manner and in the improved apparatus herein described.

It is the purpose of my invention to provide an apparatus in which such fuel may be burned efficiently with little if any trouble to :the users for all domestic purposes. On all farms there is an abundant supply of fuel of this character that ordinarily is not utilized in any way and is a waste production; but when utilized in the manner proposed the farmer will not be required to make any expenditure either of cash or labor for obtaining coal or wood.

The invention consists in employing a magazine, in which the straw, &c., is packed in such manner that there is formed in the body of the fuel and passing through it a draft fine or orifice that is surrounded on all sides by the fuel. The magazine is open at each end of the flue, and is to be removably placed in any suitable holder,support, or stove-casing in such manner that the draft-flue therein is in an upright position, or substantially so, and so that the air to support cornbustion is admitted by means of suitable draft devices at the bottom and passes up through the flue in the fuel. The fuel may be lighted at the top and the products of combustion conducted off in any convenient way.

All cooking operations may be conducted over the top ofthe magazine-such, for instance, as boiling, broiling, &c.-aud, if it is desired to bake, a Dutch oven may be placed over the fuel-magazine or permanent ovens may be provided as part of the stove.

In carrying out my invention I compress the straw or other ,material into a cylinder, the package forming a magazine to be placed in a stove designed for the combustion of the material. In practice I prefer to compress the material in an iron cylinder by means of any suitable compressor, or it may be done by hand or trampled in with the feet. The cylinder in which the straw is compressed may haye solid walls and be open entirely or partly at top and bottom, .or the walls may have any desired number of perforations, openings, or apertures therein. The only requisite is that the holder, of whatever material or however constructed, should be of a proper character and of suificient strength to retain the compressed straw or other material therein. I pack the material in the cylinder or holder around a core, which may subsequently be withdrawn, thus leaving a draft fine or orifice through the body of the fuel.

In testimony whereof I have hereunto subscribed my name.
