f Letters Patent No. 90,141, dated May 18, 1869.

The] Schedule referred to in these' Letters Patent and `making party of the sama.

Be it known that',DAvIDWELLS, of Lowell, in

l y the county of Middlcsex,and State of Massachusetts,

have invented anew and useful Improvement in Stoves; and I do hereby declare thesame to befnlly described i in the following specification, and represented in th accompanying drawings, of which A i Figure 1 is a vertical section, and -FiguI- e 2, ahorizontal section of a stove provided.

Patent, N o. 22,392', were granted to me for au iuvention having referencel to stoves or `furnaces. In the stove embodying that invention or improvement, thedischarge-opening leading into the exit-flue fwas arranged `at the lower part ofthe back, and it opened directly out of the chamber for tiring or burning the waste gases and carbonaceous products Iof the While in my present stove Ifret'ain the said chamber, with its openings or ame-inducts, and the lateral i and vertical ilues which are on its tlanks, and ,dispense with the chamber for supplying air tothe gas and i smoke-burning chamber, I (for the pnrposeof carrying outmypresentinvention)'combine, with the said smoke- Aconsuming chamber and its `fines .and flame-inducts,

\ another chamber or radiatoryto extend up against theback of the stove, and betweenf it and the gas and smoke-consuming chamber; andfI provides'uch auxiliary chamber or radiator with au exit or dischargeopening, arranged at its upper part.

Furthermore, I form, in the partition which separates the fire-place from thesmoke-consuming chamber, a rectangular or other proper-shapedV opening, which I cover by a separate plate of metal, or other proper material, having a Series of flame-inducts or i holes made through it, each of which is in the form of afrustum of a cone, or is made tapering, withthe larger basetoward the smoke-consuming chamber.

f By so making the holes, they will not easily become 'clogged by ashes or cinders, as they are liable to when constructed without any taper.` Furthermore, with "the opening through the partit-iemand the separate i perforated dame-duct plate to. extend across and be fixed thereto, in manner as hereinafter described, 1t

becomes an easymatter, atl any time, to substitute a new plate for one which may have become cracked `or `otherwise damaged by the heat ofl the fueho'f thefire- In rear of the fire-place is the smoke-consun'iing chamber G, which communicates `with the lire-place 1by means of two vertical lucs, H` H, arranged-on the Banks of such chamber G,'and opening both into it andthe lire-place. 1 f

` The partition between the chamber G and the irei The said `plate is heldin place by lugs it', which extend from the partition, and lap on the plate.

I n 'rear of the smoke-consuming chamber G is the heat-radiating chamber M, which at or near its bottom, opens into the lower part of the chamber G.

The opening for the discharge of smoke from the chamber M is shown at N, the fire-place and ash-chamber doors lbeing represented at O P.

G will heat the back of such chamber, the heat absorbed by such back being transmitted through it, and radiated into the auxiliary chamber M, where it will bertaken up by the spent gases and smoke which may bethel-ein, (or may have `escaped. from the chamber G,) and bysuch will be transmitted to the back of the d .from the rire-place in jets through the holes at its back.

My present stove ,will heat-a room to much better advantage than the stove above mentioned as heretofore patented by me, for, in my present stove, instead of the waste smoke and heated gases of the smokeconsuming chamber G being led directly into'a dis-g charge-tine, as they are in the patented stove, they are led into and made to flow through the auxiliary chamber M before they escape from the stove. Thus their heat will be imparted to such chamber or its back, and they will also serve as a means of absorbing heat from the back of the smoke-consuming chamber, and `transmitting such heat to the Ybacks of the radiatingchamber. L

In Y the stove as heretofore pateuted'by me, I employed, at the back of the smoke-consuming chamber, an Vair-receiving' and heating chamber, having holes for `discharging air into the Smoke-consuming chamber. I found that this air-chamber so cooled down the volatile-products in, the smoke-consuming chamber as to prevent or greatlyimpede their combustion. 4Therefore,in carrying out my present invention,I have dispensed with such air-chamber, and employed the auxiliary smoke-passage or chamber M, arranged in rear of the chamber G, such chamber M serving to maintain the spent gases and smoke of thechamber Gr at the proper temperature for being consumed or burned.'

The chamber M is also productivev of other useful `effccts,as hereinbefore mentioned. i

Therefore, l herein make no claim to the combination ofthe smoke .and gas-consuming chamber, its lateral or anking dues, and its front or dame-holes with The smoke and waste gases burned in the chamber.

the fire-place; nor with the same and an air-supplying chamber, as represented in the said patent, No. 22,392; but

What I claim as my present invention is as follows; that is to say- I claim the combination of theiauxiliary chamber M, having the disehargeopening N arranged in the upper part of it, with the fireplace B, the smoke-consuming chamber G, its vertical ues H, and front `flame-holes h, the whole being substantially as de'- scribed.

I also claim a stove as made not only with the smokeconsuming chamber G, the vertical ues H, and fire- DAVID WELLS.
