    Geary s Improvements in the Preparation of Fuel. the manner in which the same is to be performed, are fully described and ascertained in and by the following statement thereof (that is to say) :—• My Invention relates to a mode of preparing fuel from certain well-known combustible and other matters as will be hereafter described; and, in order to give the best information in my power, I will in the first place state the various 5 matters which may be employed in preparing fuel according to my Invention. First.—Pitch or such like bituminous matters obtained from coal tar or from other mineral or vegetable tar, or from india rubber (caoutchouc) - Secondly.—Coal cinders or coke, or powdered peat or bark of trees pulverized, or sawdust, or tan, such substances or matters being in a dry state ... Thirdly.—Clay, dry and coarsely powdered, or, instead of clay, fine sand may be employed or free stone powdered, or chalk, or plaster, or earth, or the cinders of wood, or generally any earthy matter well powdered and dry Fourthly.—Small of coal Fifthly.—Acids - 1000 parts. 100 parts. 10 187^ parts. 15 187^ parts. 500 parts. 25 parts. Now I would remark that I am aware that most of these matters have been before used, or proposed to be used for the purpose of fuel, and they have been combined together in varied proportions, I do not therefore lay any claim to the same separately or combined when not according to my Invention as here¬ after stated and accurately defined. The above-mentioned materials, or some of them, are to be blended together, and prepared into a fuel in the following ^ manner:—The pitch or matter named as the first material is to be melted in a suitable large vessel, and the cinders, or some one or more of the matters mentioned secondly, are to be gradually introduced amongst the melted pitch, keeping the matters in the vessel constantly stirred. The clay, or some one or more of the matters mentioned under the head thirdly, are to be gradually gQ applied and well stirred into the matters previously in the vessel, heat being constantly kept up to the matters so being mixed. One half of the small coal may now be gradually supplied and stirred into the mixture in the vessel, and stir the matters well together till the whole mixture is equally and well heated, then pour in the acid, still stirring (I prefer sulphuric acid, that acid being the gg cheapest for the purpose, but I do not confine myself thereto, as other acids may be employed which will produce a like effect), which will produce a froth; and sosoon
