Letters Patent No. 114,260, dated May 2, 1871.

IMPROVEMENT IN BASE-BURNING STOVES.-

The Schedule referred to in these Letters Patent and making pari: ofV the same.

To all whom it may concern:

Be it known that we, EsnK BUssEY and CHARLES A. HAMLIN, of Troy, in thecouuty of Rensselaer and State of New York, haveinvented certain new and useful Improvements` in Parlor-Stoves and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon which form apart of this specification.

The nature of our invention consists- First, in lthe arrangement of a coking-chamber above and disconnected from the hre-pot, and connected with the fuel-rescrvoirby an open grate.

Second, in the fuel-reservoir, provided with perforations, covered on the outside with tubes to conduct the gases from the reservoir through the grate and into the coking-charnber.

Third, in the arrangement of the cokingchamber, grate, and reservoir, with its perforations and tubes, andan air-chamber and damper.

Fourth, in the arrangement of the top of the stove.

In order to enable others skilledin the art to which our invention appertains to make and use the same, We will now proceed to describe its construction and operation, referring to the annexed drawing, in \Vl]iC1Al-I Iligdre 1 is a longitudinal vertical section of our stove;

Figures 2 and 3 show'variations in the construction of the fuel-reservoir; and

Figure 4 is a horizontal section through the fuelreservoir.

Figure 5 shows a section of the reservoir-,with one row of perforations and covering tube on the outside.

A represents the ordinary fire-pot or receivingchamber to receive the coke made in the cokingchamber B.

lhis coking-chamber B is suspended above and a suitable distance from the firepot A, and above said aching-chamber B is a grate, O, to supply the same with draught, said grate extending close up to the fuel-reservoir or magazine H.

The shell of the stove around theupper portion of the coking-chamber B is perforated as shown at F,

`leaving an air-chamber, G, between them, thus sup- In the fuel-reservoir or magazine H are made openings J J, which lead into and are covered by pipes or tubes I I, formed on the outside of the reservoir Vfor the purpose of carry-ing olf the waste gases which form in th'e reservoir and prevent them from escaping into the room through the upper portion K ofthe stove, said portion being made perforated, as shown, or otherwiseof open work, to prevent the reservoir from becoming heated and the coal from colring iu the same.

The gases carried off from the reservoir by the tubes I pass through the grate O into the colring-chamber B, the tubes for this purpose extending downnear to the lower edge of the grate, and their inner sides left open, as shown in iig. 5.

The fuetreservoir- H may be made all open work, with ya casing around it, as shown in fig. 2, or it may be made of rings and outside casing, as shown in tig. 3.

L is anvair-tight cover to close the top of the fuelreservoir. Y

M is the out-er cover, hinged or pivoted on one side, so that it can be thrown open when fuel is to be supplied to the stove.

In the top of the cover Mis an opening, O, covered by a hinged cap, P, which may be made -in the shape of an urn.

This cap'is connected with the. cover L by a strip, N, as shown. f

The method of operating the stove is as follows Fire is kindled in the ordinary manner in the tire pot A, and draught is admitted below the grate,as is generally done', the reservoir H, coking-chamber B, and {ire-pot A being all lled with fuel.

After the fuel iu the fire-pot A becomes well ignited the draught below the grate is closed. Then the draught is taken iu from the door or damper at D through thegrate G and colring-chamber B, thence in the duc of the stove. The object of this is to keep up combustion in the coking-chamber B and pass the gases from the fresh fuel in the reservoir H through the burning coke in the chamber B audoverthe buruing coke in the pot A, thus becoming highly heated before meeting the currentvofair admitted through the openings in the gas-ring E.

At the grate C, as crust willfform from the freshv fuel as it is coking and a small quantity of gas or smoke arise to the top of the magazine, and for the purpose of carrying olf this waste gas, we make the openings J and cover them by pipes I, and carry the same to the burning fuell iu the chamber B, and thence into the lues of L the stove.

When the cap P is in position over the opening O the cover L closes the `top of the reservoirH, preventing the escape of gases from the coal coming into the room.

' When necessary to add vfreslrfuel to. the reservoir H the cap P `is turned over, which raises the cover L and makes a downward draught, carrying o the waste gases in the reservoirthlough the perforations J and tubes I, into the chamber B. The outer coverM can .T, which are covered on the outside by the tubes 1,'

for the purpose of conductingv the gases from said l reservoir through the 'grate Gand into the cokingchamber B, substantiallyas herein set forth.

" 3. The arrangement of the coking-chamber B, grate (l, reservoir H with its perforations J and tubes I, chamber Q, and draught-door D, n.11 substantially as shown and described.

4. The combinationof the hinged or pivoted cover M with opening O, cap l), connecting-strip N', and cover L, al1 substantially as and for the purposes here in set forth.

In testimony that we claim the foregoing as our own we-ax our signatures in presence ofjtwo witnesses.
