H EATING-STOVE.

EJPECIFICATION forming part of Letters Patent No. 352,879, dated November I6, 1886. Application filed December 26, 1885. Serial No. 186,672. (No model.)

To all whom t may concern.:

Be it known that I, EUGENE L. MESSENGER, a citizen of the United States, residing at Fulton, in the county of Oswego and State of N ew York, have invented4 certain new and useful Improvements in Heating-Stoves; and I do hereby declare the following to be afnll, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same-reference being had to the 'accompanying drawings, and to letters or figures of reference markedy thereon, which form a part of this specification.

My invention relates particularly to that class of heating-stovewhich is supplied with means for taking fresh air from out-of-doors, heating it, and throwing it out into the room, such stove being provided with a foul-air flue for freeing the room of the foul or vitiated air, and my invention consists in the improved arrangement and combination of the foul-air iiue with the other operative parts of the stove, in a manner which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a vertical central transverse section of my improved stove.' Fig. 2isa rear view of the same with portions broken away. Fig. 8 is a horizontalsection of Fig. 1, taken in the line x x. Fig. 4 is 'a section of a modification. Eig. 5 is aperspective View of improved stove with portions broken' away, and Fig. 6 is a similar perspective of lower portion of same.

Referring to the drawings, it will be seen that the stove to which my improvement is applied is provided with the usual fire-pot, a, ashpit b below, and fuel-magazine e above. At the base of the stove, and extending entirely across same, is the low chamber d, into which opens the passage d', communicating wit-h the air of the room, and the passage d, communicating by means of pipe d3 with the outside fresh air. The chamber d opens into two ver-A tical chambers, e-one on each side of the ashpit section-and these in turn open into four corner vertical flues, e', opening at their tops into the space e2, upon the upper wall of which are the openings e3. p

It will be clearly seen by means of the series of arrows that the air both from the room and from the outside is carried through the various chambers of the stove, there heated, and then passed out into the room at the top.

' At the rear of the stove are located the flues for carrying off the products of combustion, arranged on either side, of Which f is the downflne, and f the up-ue. Boththese iiues are connected with the fire-box andwith the smokepipef2, leading to the chimney, and go to form the customary direct and indirect drafts of the stove, the damper f3in the up-ue f serving to change the draft,.as required. Centrally arranged between these two fluesf andf is my Y improved foul-air Hue g, having the open end g at thebottom leading into the room, and at the top the opening g2, into which is fitted the smaller pipe g3, which'passes centrally up the smoke-pipef2 to a height somewhat above the point where the draft-fines enter such pipe. The foul-air iiue g is provided with a door or damper, g4, at the bottom to o pen or close same.

In the operation of my improved construction just described, the foul-air iiue is designed to be used when the fresh airwfrom outside is taken into the stove through the pipe d3. It is a well-known fact that when you add fresh air to a room an equal quantitynlust be taken out, which I accomplish by making a door or damper, g4, in the foul-air flue, and as the fresh heated air is thrown out into the room the foul air has a tendency to enter and pass up the flue g into the smoke-pipej', and out through the same. The relative amounts of air in the foul and fresh air passages can be regulated by said door or damper.

I am aware that a foul-air flue has been heretofore arranged with a stove, but in such a manner that the foul air, not being sufficiently heated, served in its upward passage to retard the draft, and thereby check the fire in the stove. I have completely overcome this difficulty by arranging my foul-air flue, as shown, between the up and down dues, so that the foul air in its upward passage is thoroughly heated by contact with the intervening heated Walls of the draft-fines, and in such heated condition it is not only readily passed-into the smokepipe, 'but it materially assists the draft of the stove, thereby serving a double purpose of effectually removing the foul air from the room,

IOO

as well as increasing the efficiency of the work- `ing parts.

In case of stoves fitted with three draft-fines, as shown in Fig. 4, in which h is the up-ue, located between the two downiiues 7L 7L,'my foul-air flue would preferably be arranged, as shown, between the two down-dues h IL', and between the up-flue 7L and the fire-box of the stove. XVhen the air is not being taken from the outside, but only from the room through passage d, the damper g4 in the foul-air flue g is to be closed.

I claiml. The combination, with a stove provided with a returnpassage for the products of coinbustion, of a passage within the stove separate from the fines of the stove, having a part of its length adjacent to the passage for the products of combustion, said passage communicating with air outside of the room at one end and at the other discharging into the room, and aventilat-ing-passage communicating with the air ofthe room at its lower end, and rising therefrom and discharging into the smokeoutlet of the stove, said Ventilating-passage having a portion of its length adjacent to the passage for the products of combustion, substantially as described.

2. The combination, with a stove provided with two vertical passages and a horizontal passage connecting the lower ends of the two, forming a returnpassage for the products of combustion, of a passage within the stove having a part in close proximity to the horizontal connecting-passage communicating with the air outside of the room at one end and at the other discharging within the room, and a foulair Ventilating passage communicating with the air` of the room at its lower end7 rising therefrom adjacent to the vertical passages of the return-Hue, and extending into the smokeoutlet of the stove anddischarging into the same, substantially as described.

3. The combination, with a stove provided with two Vertical passages and a horizontal passage connecting the two lower ends of the two7 forming a return-passage for the products of co mbnstion, of a passagewithin the stove having a part in close proximity to the horizontal connectingpassage communicating 4with the air outside Iof the room at one end and at the other discharging within the'room, and a foulair Ventilating-passage communicating with the airwithin the room at its lower end7 rising therefrom between the vertical passages of the return-Hue, and extending into the smoke-outlet and discharging into the same, substantially as described.

In testimony whereof I have signed myname to this specification in the presence of two sub scribing witnesses.

EUGENE L. MESSENGER.
