To ll whom itfma concrm.. f

i e it known that I, SMITH Gnooivt, of the city of Troy,icounty of Rensselaer, State of New York, haveinvented new and useful Improvementsin ``and for the Consumptioni of Fuel andthe Products of Combustion in Stoves, Furnaces, Boilen` and Locomotive` Engines, Sto., and I do herebyfldeclare that the following is a full, clear, and 'eXact description of the same, reference being had to the accompanying drawings, and tothe letters of reference inarked thereon,` i i i i Like letters refer to and representcorresponding parts. i

'fl my |improvements described in this specification consistsin the introduction of steam into annular' retort-chambers,where,-

by theintense heatof said chambers, said steam is decomposed into hydrogen, which is i .ad mitted from such chambers at or` near the i lower part of the `fire, and also overthe fire in f the same fire chamber; or the steam may be admitted directly to t-he fire by enlarging the apertures'rherei nafter described, in said' annular chambers and raising the steam to a higher Upressure Liu said ehambers or their equivalents, to accelerate combustion and economize`` ``in ``the use of fuel, Sto.`

I In the accompanylng drawings, B, Figures 1, 2, 3, and 6,1`s the boiler, containing water for the purpose of generating steam'uto supply `the annular steam and retort chamber O, also to supply the `annular` steam and retort pipe `N, Figs. 2 and 8, or any pipe or chamber being an equivalentfor one'or both of said annular chambers,with steani,which are connected withthe said boiler` by the respective pipes D O. `The said annular steam and 'retort chamber O has apertures a, Figs. 2, 3, and 4, through which the hydrogen: or` the steam aforsaid is The chamber' and fire-chamber is highly heated by i the fire in said ;fire-chamber, and thus and thereby highlyheats said annular chamber,

r whereby the steam therein coming in contact with the saineiheated red-hot becomes highly heated` itself, andis decomposed into hydrogen, which is then admitted to the lower part Uof the said` fire-Chamber,1 as aforesaid; or the steam may be admitted directly to thispart of the fire, as hereinbefore provided, when the same will be decoinposed'into hydrogen by passiug` up into or through the said fire, ,and thus coming in contact therewith. y

The steam in the annular steam and retort pipe N,-Figs. 2, 3, and 5, becomes highly i heated while thercin by reason of the heat or fire below arising and coming in contact with the same, thereby heating the said annular pipe red-hot, whereby the said steam thcrein isldecomposed intohydrogen, which is then admitted through apertures 'i in thelowerside of said`annnlar pipe N, -Figsl 2, 3, and 5, to

the products of combustion above the fire. V`

The hydrogen thus ad mitted to the lower part of the fire unites with the carbon produced vfrom the fuel in said fire-chamber, the heat of which passes up through the sarneand unites with the hydrogen admitted to the products of combustion over the said fire/through the aforesaidannular steam and retort pipe, and thus and thereby creates an intense heat with a small consumption of fuel. The said fire-chamber is supplied with fuel through the door l, i

Fig. 1, which` door is then closed perfectly air-tight. The boiler B is supplied with water through the supply-pipe H, Figs. 1 and 6, which pipe may be connected with a rcservoir for water. i i

No air is admitted to the fire or any part thereof. The entire structure is constructed air-tight, so that air is only admitted to start ,the fire and generationiofl steam, which, when done,is then shut out. Any kind of combustible material may bensed in the said firechamber, and will he required only in small quantities after the steamshall have been `admitted to said annular steam and retort chamber and pipe, or to the equivalents of either or both of said annular steam and retort chamber and steam-pipe, as aforesaid. .The quantity of steam required for 'use in the said chamber'and pipe is regulated by the stopcock77 Win the respective pipes D and O,n

Figs. 2 and 3. Having thus described my improvements,

what I claim, and desire to secure by Letters Patent, isw The introduction of hi glily-heated steam into the fire-ehamber by means of annular eham- In testimony whereof I have, on this 17th bers or pipes surrounding' the said fire-chamday of February, 1862, hereunto setmy hand. ber on the inside thereof, and having therein apertures through which such steam or hydro- SM [TH GROOM. gen is admitted into the fire around the outside thereof, Whereby conlbustion is greatly Witnesses:

aided and the fuel economized, substantially FRANKLIN SCOTT,

as herein described and set forth.' MAROUS P. NORTON.
