FIRE-PLACE AND HEATING-STOVE.

SPECIFICATEON forming part of Letters Patent No. 330,516, dated November 17, 1885.

Application filed November 13,1884. Serial No.'147,884. (No model.) Patented in England January 7, 1884, No. 887; in France October 6, 1884, No. 164,627, and in Belgium October 6, 1884, No. 66,513.

gium made, respectively, on Octoberfi, 1884,)

of which the following is a specification.

The object of the invention is to effect the more efficient warming and ventilating of apartments and other places with economy of the fuel employed and with the better preven tion or consumption of smoke in combustion of the fuel in the fire-place.

The principal features of my, invention are the fire-place, which is formed of suitable form and design for holding the fuel during combustion; a box or chamber behind the fuelchamber, for the purpose of holding asbestus or other suitable refractory material capable of being renderedincandescent for the purpose of burning the gases or smoke passed through it; a hood or deflecting-damper capable of being adjusted in its position in the course of the flue, to intercept Whollyor in part or to leave free, as desired, the passage of smoke from the fuel with the other products of combustion, and deflect them downward at will through the heated material in the said rear chamber; a channel or channels from the lower space below or behind the fire to the flue above or beyond the fireplace, forconducting them away to the air, and a channel or channels of fresh or cold air extending below or behind the fire-place. This principle of construction according to my invention admits of considerable variation in arrange ment, dependent on the size of the fire-place suited to the place to be warmed and ventilated, and whether the stove already in existence is to be reconstructed or modified to my improvements or a new one substituted, or the conditions of. the situation generally.

A convenient method of arrangement generally adapted to the modification of existing fire-places to my improved construction is to remove the back of the grate and to incase the sidesand bottom with fire-clay, (if not already so provided.) Then to the rear of the fuel-space I apply a body of asbestus or other refractory substance that can be maintained at a red heat, so as to close the flue-passage except by passage through that heated material, after the manner of a filter. Above the fuel-space I again close the fuel-passage by means of the damper or hood, which serves to intercept and conduct the products of combustion from the fire downward through the heated material referred to. Thence these products of combustion, rendered less noxious by their passage therethrough, pass, mixed with incoming hot air from below the fire-place, by suitable channels in the sides or other parts, to above the fire-place into the flue and pass away. The asbestus, or its equivalent, is retained in position bylneans of a grating or open-work division or divisions. This asbestus mass prevents the heat passing away up the flueor chimney,and causes the heat of the burning fuel to be radiated back into the chamber or room. On first lighting the fuel and until sufficiently alight the intercepting hood or damper may be drawn or pushed from over the fuel-passage, so as to give direct upward vent to the products of combustion, and be afterward replaced partially and then entirely, as desired.

,For larger-sized fire-places, and where the situation is not hampered by existing arrangements requiring to be utilized, I find it convenient to somewhat modify the foregoing construction, so as to bring the burning fuel well forward, and I arrange the in'terceptinghood or hollow chamber or channel so as to return the ascending products of combustion behind the fire-place and through the mass of incandescent material-such as asbestus-located in rear of the fuel to the hottest portion of the burning fuel below, and thence to cause the resultant purified gases to flow by a suitable channel to a chamber below, where, mixing with air supplied from without, those gases pass by side or inclosed channels to the fiue above or beyond the fire-place, for delivery into the atmosphere deprived of their noxious particles. The intercepting-hood or deflectingdamper is removable for facilitating first lighting of the fuel.

For smaller arrangements of heating and ventilating apparatus, it is convenient in some cases to modify the construction according to my invention by forming the hood ordefl'ecting removable part above'the fire in a somewhat simpler manner, and yet to insure the products of combustion passing downward through a similar mass of incandescent matter in rear of the fire to, below, and past the hottest part of the burning fuel, whence, mixing with air supplied by a suitable inlet, the re-' sultant gases pass by a channelorchannelsup the sides or back of the grate, stove, or fireplace to the flue, for dispersal into the atmosphere. Suitable curved or other shaped plates in either arrangement may be appliedto assist the proper conduction of the currents of air, gas, or products of combustion. rounding parts most exposed to heat should be formed of fire-clay or fire-brick material. The upper front portion of the hood or intercepting and deflecting damper should in some cases, where much exposed to direct heat, be lined or coated with asbestus or other suitable non-conducting material. Suitable guards or baffle-plates are employed when desirable to prevent the entrance of undesirable matter into the air-channels or gas-passages and-to promote circulation. It will be found one of many advantages of this plan of construction that it lends itself with great facility to various descriptions of ornamentation and diversity of forms of design. Warmed air may be supplied to the chamber to be heated and ventilation promoted by means of openings at the sides of the stove or fire-place by which air can pass to be'warmed by the heated channels referred to, and when-warmed to flow into the chamber; but that the nature of the invention may be the better understood, I will proceed by the aid of the accompanying drawings to describe the same more in detail.

In the-drawings, Figure 1 shows by a sectional view, Fig. 2 by a frontview, partly in section, and Fig. 3 by a plan -vieW, an arrangement of stove or fire-place and parts adapted for carrying my invention into effect, either when the conditions of the situation are suitable or the space has been adapted specially for the purpose in an apartment.

a indicates the space for the reception of the fuel to be burned, and of which a a are the side cheeks or walls, and a the bottom, all formed of fire-clay.

a are the front bars.

a indicates the front of the stove, facing into the apartment.

a c indicate a space available for tile or other decoration, as is well understood.

b is a chamber or space behind the fuelspace, filled with asbestus or suitably refractory heat'resisting material maintainable in a highly-heated condition, which material closes the flue-passage through 6, except through the The surinterstices of itsown substance, so that gases passing from b above to b below that mass in the direction of the arrows pass therethrough as through afilter. The flue-space b is again closed above at b by a hood or closing-plate, which serves to intercept the gases and products of the combustion of the fuel in a and deflect them wholly or in part, causing them to pass through 12. The closingplate at b can be operated by a rod, b, and

handle b, so as to be turned or removed to open that passage b direct to the flue b upward, as occasion may render desirable, and especially for a short period upon first lighting the fuel.

I) b are louvers or open partitions, respectively dividing the fuel from the asbestus and the upper part of the fire-place from the fluespaceb, but affording ready passage to the gases and smoke.

0 indicates a space which may, if desired, be utilized to receive a pan to catch ashes from a, in which case the fuel-space or firepot a should be provided with an open-work bottom. The division-plate b*, dividing the space b from 0, may be applied farther to the front to enlarge that chamber or space b accordingly. The under space, b, communicates with b b, arranged one on each side of the central flue, b, or one on one side only may be used, which in turn communicatewith the flue-space b to carry ofl the filtered products of combustion.

d d are perforations in the plates or walls of the fireplace dome and back for the escape of such smoke as may ascend beyond the openings in the partitionrb b are bars ,to support the asbestus.

It will be observed that the passage b, when closed by the plate or hood b", commucates with the flue orfiues b or b" by way of the under space, b, only at the bottoms of these flues, and therefore that in this condition the passage b becomes a chamber, closed at top,

but open at its bottom, which supports the asbestus or equivalent material. This passage or chamber thus in conjunction with b or 1) becomes a siphon, and the products of combustion cannot rise and escape until they shall have first passed down and up through this siphon, and in so doing must of necessity pass through the whole mass of heated asbestus or equivalent material, and get the completest filtering attain able.

Prominent among the many advantages arising from this improved arrangement or construction of stove or fire-place and fueleconomizing means are, first, economy of the fuel employed second, simplicity oflconstruction or adaptation third, consumption of smoke or its denser particles; fourth, prevention of accidental fires in the fiues, arising from the dense deposits of carbon; and, fifth, nonliability to downblows of soot from the like causes, to the detriment of comfort and the injury of furniture and decorations.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In combination with afire place or grate closed at its bottom, a chamber or flue-space at its rear, a damper in said flue-space at a point or line above the grate, and the flue having an open-work bottom to support as closing-plate serving to close or open at will the passage 1), as and for the purposes described.

3. The combination, in afire-place or stove having a grate or fire-pot open at its front, top, and back, of anopen-work support at its rear, amass of asbestus or equivalent material upon the support, the passages 12 and b 72, b and b the latter communicating with the outlet-flue, the adjustable hood or plate 12 and'the perforated walls in the dome, substan tially as and for the purposes set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
