'specification of Letters Patent No; 1,005, dated November 12,1838;

`TooZZ whom t may concern; D D l Be it known that I, THOMAS Oron, a subject o-f the Queen of Great Britain, now residing in Camberwell New Road, in the county of Surrey and Kingdom of England, gardener, have invented or discovered a new and useful invention of improved or prepared fuel for warming` and heatingrooms, churches, factories, or other buildings, hothouses, carriages, and` other places or things requiring artificial heat and an improved stove or apparatus to be used with the same; and I do hereby declare that the following is a full and eXact description thereof.

These improvements consist inthe `first place in preparing charcoal in such a ma`nner as to render it lit and proper for burning or being consumed in rooms, factories, churches, carriages and Otherrplaces requir-` ing artificial heat without throwing off or giving out the deleterious vapors which arise from the combustion of charcoal not so prepared or in the state in which it is'fusually sold as an article of commerce. The charcoal so prepared may be consumed in stoves or apparatus without a chimney as all the deleterious vapors (carbonio acid gas, &c.,) which arisefrom the combustion of unprepared charcoal are, either neutralized, abstracted or consumed in the course Offsuch preparation and consumption and therefore the `heated air and vapor arising `frornithe combustion of the prepared charcoal may, safely be allowed `to escape into the atmos` phere within the room or building without edecting the lungs or health of` persons breathing the same. And secondary indimprcved arrangements and constructions of stoves or apparatus to be used with the so prepared charcoal for the better carrying the objects and intentions of my improvej ments into effect and I will proceed to dcscribe the manner, method or process of so preparing the charcoal and then de-` scribe the improved constructions and arrangements l Of stoves or apparatus to be used with the same, referring to the vdrawings hereuntov annexed which are representan tions of two kinds or constructions of such stoves or apparatus applicable to these purposes.,` -I ,l L

I Vfirst take the charcoal as it is usually charred orconverted fromadifferent kinds of wood andsold by the charcoal burner; 'I break the same into lumps or pieces of from about one to two inches cube measure.

I then immerse and: saturate the saine (or nearly so) 1n a solution of alkali Acontaining as smallvaproportion of carbonioaeid as I can procure Iit, say sub-carbonate of soda, which maybe readily purchased in coinmerce, or caustic alkali and water, .in the proportions of about three pounds of common soda (sub-carbonate) such as is'usually sold in commerce dissolved in about twelve gal.; lons of water; but I do not confine myself to these quantities. as the proportions may vary accordinfr to the quality and nature of the soda `or alIzali. After the charcoal is `so 'saturated or partly prepared it is allowed to drain and dry 4in a partial degree whenit may be u sed as fuel in one ofthe kinds .or constructions of stoves or apparatus l secondly hereinafter described or it may be taken to a purifying furnace where the charcoal is further purified and its preparation completedso as to render` it fit formthe other kind or construction ofstove or` apparatus first hereinafter described, the difference in the construction of these two kinds ofstoves or apparatus being, that in the one first described the heated air and vapo-r arising frorn'the combustion of the completely prepared charcoal may be allowed to escape at Once into the atmosphere through the` bodyT of unconsumed fuel, whereas in the second described `stove or 'apparatus the impure vapor arising from the combustion of the partly, prepared charcoalisobliged to descend through the fire. and burning fuel before it can escape to the atmosphere. And as I prefer completing the process Ofpre-4 paringor purifying the charcoal pervious to burning it in a roo1n,'carriage or other situation Vwhere persons are breathing the air within, I shall proceed to describethe fur ther process of preparing or purifying the said fuel and the kind of furnace I use .for effecting the same. f

After the charcoal has beensaturated and allowed to drain as above stated it is to be taken to a purifying 4furnace such asthat `shown at Figure l which is a front Velevation of one construction which Ihave found to answerthe purpose, Fig. 2 being a vertical section taken through the same. p

a, a, is the tower or chimney of the furnace into which the partly prepared Orsaturated charcoal isiintroduced atthe top part, this` chimney may be constructed of iron-or other suitable material and is formed'with the inclined plane or mouth piece b at its lower end to facilitate the removal of the fuel.

d is the opening or aperture by which the fuel is removed when required and is furnished with a door pierced with holes ifV necessary. n

The tower or chimney may be set in brickwork e, e, as shown in the drawing or supported in any convenient manner.

f f are apertures formed through the brick work and the tower for the admission of air to support the combustion o r ignition of the fuel under process of operation.

When a suiiicient quantity of the partly prepared or saturated charcoal is placed in the furnace it is to be ignited at the lower part, the draft causing it to burn. The charcoal is allowed to continue in a state of ignition or combustion until it becomes thoroughly red hot and as soon as itis so it may be removed through the aperture d, other charcoal continually falling down as that which is red hot is withdrawn which Vimmediately it is taken out of the furnace is put into a tank of vessel composed of iron or brickwork and closed tight by means of a lid or cover so as to exclude the air when the combustion of the prepared charcoal will be immediately stopped and extinguished in a short space to time. The now completely prepared charcoal may then Ibe removed from the tank and allowed to cool, it being in a purified state fit to be used in any open stove or apparatus or such as is hereinafter first described. The process of purifying may be continuous, fresh partly prepared or saturated charcoal being added to the furnace and removed as it becomes red hot and immediately extinguished and cooled as above stated. Y

Having now described my method or process of preparing and purifying charcoal I would remark that other alkali than thatl I have mentioned (sub-carbonate of soda, &c.,) or rather alkali in a different state,V may be used in the above preparing andl purifying process and also that some of the alkaline` earths may be used for the same purpose although not with such good effect. And further some or one. of them may be employed in conjunction with soda or other caustic alkali. For instance, a solution ofV lime and water may be employed; but if lime is used it should be newly made as it absorbs carbonio acid from exposure to the atmosphere and would therefore be uniit'for this purpose and it will of course be understood by all practical chemists that soda or other alkalis possessing a too great proportion of carbonio acid will be improper for this purpose. I therefore do not intend to confine myself to the use ofsub-carbonate of soda, my invention being the preparing and purifying charcoal by means of alkali in solution and the application of heat ashereinbefore described and` I have only stated in the foregoing description that which I have found to answer the purpose well and I will now proceed to describe the improved arrangements and constructions of stoves I have found to answer best in using the said prepared charcoal and for regulating or inofice and will containsuiicient fuel for about 24 hours consumption keeping the atmosphere in the room or ofiice in a moderate degree of temperature butl the dimensions may be increased in proper proportion more in height than diameter.V Fig. 'et is a vertical section of the same. a a is the casing of the stove supported upon the bottom plate b and the pillar and claw stand c. The top or cover d ts'over theedges of the case and is to be removed by lifting it oif when the fuel is to beintroduced into the stove. f is a hot air pipe passing through the center 0f the stove the lower end being open to the atmosphere, the upper end projecting into theitop part of the cover; this pipe is kept in its proper situation by means of the guide'or stretcher g. At the top of the cover a contrivance is placedfor regulating the draft through the sto-ve and consequently the heat given out and also the combustion of fuel. It consists of a sliding hollow stopper or damper z shown attached at Fig. 5. Fitting inside of the top part of the cover Za k are apertures formed in the part v1 and vby raising or lowering the damper 7i. These apertures will be opened or closed.v Z Z are holes formed in the bottom part of the stove for the admission of air to support the combustion within, the open worked ornamental/border m being placed so as not' to prevent the admission of air through them. At the same time it prevents `any sparks or dust falling from theV stove. The direction of the draft through the stove is shown by the arrows. 'n n, are handles for the convenience o'frmoving the stove from one place to another. y

In order to ignite the prepared fuel in the stoveI prefer when it is convenient first making a small quantity of it red hotin a shovel or ladle placed in aV common kitchen or open coal fire and then placing it Vat the bottom of the stove andthe rest of the re- Vquired quantity of fuel above it ,which will Aimmediately ignite.

But this improved fuel may be ignited in any other way as common charcoal, coke or'other fuel may be ignited but when this is the case it should be done `out of doors or in another room than that in which the stove is intended to be `placed las ithere will be `some disagreeable vapors arisingfrom the materials used to ignite the prepared charcoal although therev will be none from the fuel itself.

Fig. 6 is a detached sectional figure of another arrangement of the damper and `former figures.

It will be seen that the `greater proportion of heat given out by this stove is by radiation no more air being allowed to pass through the stove than is required to support the combustion in the required degree. Fig. 7 is another sectional figure of a small stove or apparatus of the same kind or construction but without the central hot air pipe and is intended to be used in a carriage or in cabins of vessels or such other situations and may be suspended from the ceiling or roof. a is the casing, b the top on cover, c the damper, @Z the apertures for the exit of the hot air and vapor arising` from the combustion of the fuel.

e e is the bottom plate.

f is another or inner bottom plate with a hollow cap g formed upon it shown detached in top and side views at Fig. 7. The air to support combustion is allowed to enter vthe stove by the aperture L formed through the bottom plates and thence through holes formed in the hollow cap g to the interior. This stove or apparatus may be suspended by means of the handle z' or by chains in any convenient manner.

I shall now proceed to describe the second arrangement and construction of stoves or apparatus intended to be used with the partly prepared or saturated charcoal as before mentioned in which the vapor and heated air is caused to pass downward through the lire or burning fuel.4 The fuel in this arrangement or construction of stove is placed in a chamber closed at the top and is ignited at the bottom part as before.

Fig. 8 is a side elevation of the stove or apparatus, Fig. 9 is a vertical section of the same and Fig. 10 is a horizontal view and Fig. 11 a detached side representation of the outer bottom plate with the parts attached thereto showing the exit aperture for the heated air. Fig. l`2 is a detached side representation of the cold air pipe and its cap furnished Vwith holes for the admission of the air to the burning fuel. Fig.l3 is a plan view of the same.

ing the chamber for the fuel; b Z2 is Athe outer casing. Between these `two cases a passage or channel c, c is formed for the pas` sage of the heated air passing from the interior of the stove to the exit aperture.

v Z is the top or cover furnished with the damper, e, and exit apertures f.

g is the lid lid or cover of the fuel chamber which is to be secured tight upon its ond bottomplate m as shown in the drawing. This pipe with its cap and bottom plate is shownde-tached in plan and side views at Figs. 12 and 13. i s

' a is the cap of the pipe 7: through' which therair enters to the interior and burning fuel; by means of the apertures o, 0.

p, p are theapertures for theescape of the heated air arising from the combustion into the passage or chamber c. The cup or ash pit q receives the ashes falling from the combustion through the holes or grating formed at 1' r in the bottom plate m and is attached to the outer bottom plate by a bayonet fastening as shown inthe drawing or in any convenient manner.

On a charge of fuel being put into this stove the cover Z is first to be removed by lifting it oif, then the cover g is to be taken out of the inner 'case 0 and a small quantity of ignited fuel placed in the bottom part when the full charge of damp saturated or partly prepared fuel may be placed inthe stove and the top or cover g secured in its place. As the fuel burns the heat will cause the damp fuel to give out steam or vapor which not being able to escape at the top part of the case c to the atmosphere will be instance or it may be constructed with a secconfined within the chamber until it acquires a suflicient degree of elasticity to force its way through the lire or burning` fuel, and will therefore become purified, all the deleterious vapors or its impurities being thereby arrested or consumed and the hot `air or vapor will escape through the apertures p up the chamber c to the atmosphere.'

Having now described my second improved construction and arrangement ofV stove or apparatus I would remark that variations may be made in the forms and arrangements of the parts of these my improved arrangements and constructions of stoves or apparatus .without essentially departing from the principles of their construction, for instance, a different kind of damper may be applied thereto and also the arrangement of the apertures for the admission and passage'of the air to support combustion may be placed diiferently. And further in some'instances the outer casing ZJ of the second construction 0f stove may be dispensed With; all of which Variations Will readily suggest themselves to any practical engineer or mechanic. And in conclusion I would remark that ii a damp or humid atmosphere should be required it is only necessaryy to place a small vessel containing Water in the top part or cover of the stove. The Water Will give out steam in proportion to the intensity of the heat and produce the desired effect.

I claim as my inventionl The' manner of preparing the fuel by means of allalis, as herein set forth; yand also the construction of the stoves for burning the same, Whether yof the first 0r second kind described, together with such variations thereofV asV are substantially the same in their operation and results. y

And further it will be evident that this prepared or puried fuel is equally applicable to the purposes for Which common or of our, Lord 1838*.

Aurns o-r vessels; also that th'e lsame kind of contrivance maybe adapted to cylinders or rollers used in paper making; machinery, calico printing, drying apparatus, Woolen manufactures and other such purposes Where employed, to all of which purposes the same may be applied proper arrangements in the details or' the mechanism `being madey accordingly.-

In Witness whereof I the said THOMAS J oYoE, have hereunto set my hand and seal this twelfth day of January in the year THOSJOYGE. [ns1] Witnesses: l
