N0 Drawing.

To all whomit may concern:

lie it l-:i:o\\'n that I, llinni"Srt'nnniu, a subject ot the King of (treat Britain. and :rresident of Detroit, in the county of Wayne and State ot Miehigain have invented a new and useful lrocess for Treating (Joke, of

-which the following is a specification.

(Yoke usually contains sulfur.principally in tlie torni o'l sulfates and sultids of iron and of raleium, etc.

ironand other metals in blast t'urnaees. eupelas and other similar tur nut-es. absoluteeontat-t or interiningling oeurs between the coke and the melted metal so that this sult'ur unites withthe melted metal tor which it has great atlinity. The present-e of more than a traee of sulfur in iron is t hjeetionahle, and more than onesixteenth of one per eent. is sutlieieut to render the iron useless tor'iuany purposes. To prevent the'sultur in the coke from uniting" with the iron. it is necessary to provide a substance with which it \\ill more readily unite when the eolce isliurned.

Home of the salts. hydrates. and oxids o'l? the alkali metals. partieularl the earhonates. are partieulartv adapted for this purpose. Sodium carlu-nate is pre'l errtal heeause it nut he dissolved in the. cheapest solvent. water, and the coke moistened therewith. the-solution being sprinkled or poured over the coke, or the (tth't immersedin the solution. Asa result. the. alkali is carried by the water into the pores of the coke where-it may reaet on the sulfur just as soon as the conditions become proper and before the stiltur can unitewith the iron. 'lhexstrength of the solution will depend upon the condition of the coke and the amount ot sultnr therein. but it should be less than a saturated solution, and the amount of carbonate should be in excess of Specification of Letters Patent.

\Yhen used to smelt.

s'rii is trsiar t t ies.


that indicated as necessary by an analysis of the coke. The water is then permitted to...,e\'aporate, spontaneously or otherwise. When the coke thus treated is used for melting iron, a soda slag is formed which contains the sulfur formerly'in the coke, and which, by analysis, has been found often to contain also a portion of the sulfur formerly united with the iron. The sulfur in the is, probably in the form of sodium sulfate and of sodium sulfid, but I am uncertain as to the exact conditions.

While sodium carbonate is the cheapest and therefore preferred substance to be employed, sodium hytrzte, and sodium oxid (Na O) and similar compounds of potassium may be employed if desired.

Having now explained my process and its advantages, what 1 claim as my invention and-desireto secure by Letters Patentis: 3

l. The process of treating coke by moisteuing with a solution of a carbonate of an alkali metal, substantially as described.

The process. of treating coke by mois toning with a solution of sodium carbonate, substantially as described.

3. The process of treating coke containing sultu-r which consists in moistening the coke with a solution of sodium carbonate to such an extent that after the solvent has evaporated, the carbonate will be in excessof an amount sutlieient to combine with the sulfur in the coke.

in testimony whereof I have subscribed this speeifieation in the presence of two subserihing witnesses.
