(No modclJ To ltZZ/zuhom zit may concern.- r r 4 Be it known that I, .Ovnes 8.11001), a .citiin the county of Steuben and State of New York, have invented new an d useful Imp rove ments in Radiators .for Hot-Air Furnaces and Heating-Stoves, of which the ibll owing is a The; object of my invention is to produce a radiator for hot-air furnaces and stoves adapted to distribute, thewaste products of combustion with the air to be heated, entering the heating-I spaces. in thin volumes, and to obtain a direct. draft from the combustion-chamber when the valves automatically. 7 The radiatoris mount ed upon the fire-pot, and is constructed with one, two, or more circular fines surrounding the combustion-chamber, each having direct communication with the fire-pot at substantially the same point, each fiue having substantially the same exit, each fine divided by a horizontal partition, and eachflne giving out'its heat in direct contact with the air to be heated. A damper is arranged horizontally in a vertical central chamber, and divides it to form the upper part of the combustionchamber and a top exit-chamber, and the han dle of this damper is so arranged in relation to the furnace-door that the opening of the the door will allow the damper to close of itself, thus allowing the gas and smoke to pass off through the valved opening directly into the top exitchamber whenthe furnace-door is open. The products of combustion enter the and, passing around beneath the horizontal partition-plate to apoint diametrically opposite, return above the partition-plate and pass into the exit'chamber at a point just above thatat whichthey entered thesaid circular fines, distributing the heat evenly through the walls to the air which enters at the base of the formed by the heatingwalls into the inclosingcase, whence it passes through the conductingpipes to the apartmentsto be heated.

2 Referring to the accompanying. drawings,

Figure 1 represents a vertical section of a hot air furnace embracing my invention; Fig.2, a horizontal section taken on the line w athrough the lower flues of the radiator; Fig. ,3, a similar section taken on, the line 51 3 through the upper or return fines of the radiator; Fig. 4, a vertical. cross-section of the radiator on the line 2 2 of Fig. 2; and Fig. 5, a view of the radiator, showing the relation. of its damper-handle to the feed-door.

, My radiator is adapted for use with fnrnaces, heating-drums, and stoves, and is de-' The radiator consists of one, two, or more concentric flues, of a suitable depth and width,

separated by an intervening space, E, and it has a vertical central chamber, F, directly above and opening into the fire-pot. Horizontal partitions G divide the concentric fines,

and a horizontal damper, H, divides the vertical central chamber, F, to the top of which the smoke-pipe connects. The inner concentric fiue, B, opensinto the combustion-chamber below the bottom of the radiator by the openings a a in the bottom plate of the radiator, which,by means of short pipes-or collars b b,

connect with openings a a in a dome, I, upon which the radiator is directly mounted, the

said domebeing mountedupon the fire-pot and forming the rcombustion-chamber. The outer concentric flue, 0, opens into the vertical centralichamber, F, by awall-opening, 0, therein beneath the damper, which opening 0 also communicates with the open ends 0 of the in iner fine, B. a The vertical walls (I d, crossing the intervening cold-air spaces, E, form a cross fine, J, which opens direct into the combustion-chamber and into the concentric fines, so that'bothconcentric fines open into the combustion-chamber at substantially the same point below the horizontal partition. at the back of the radiator, as shown in Fig. 2. The

horizontal partition G of the inner concentric flue, B, is open at K at a point diametrically opposite the wall-opening c, and at this point K the inner concentric fine, B, below the partition G, opens into the concentric, iine B above said partition, which upper flue, 13, I such pressure, the damper closing as soon as opens into a vertical central chamber, F, by a wall-opening, e, and the cross-flue J at a point above the damper directly over the lower back wall-opening, c, of the central flue. The horizontal partition G of the outer concentric flue, O, is open at L at the front of the radiator, and at this point L the outer concentric fine, 0, below the partition G' opens into the concentric flue 0 above said partition, which upper flue, O, opensinto the vertical chamber F by the wall-opening e. The vercal walls at d, which cross the intervening coldair spaces, E, form a cross-flue, J, which opens direct into the top exit-chamber and into the concentric flues, so that both concentric fines open into the central top exit-chamber at substantially the same point above the damper of the central flue. By this construction the products of combustion pass from the combustionchamber into the lower crossflue, J, and, entering the concentric flueswhich open thereimpass around both sides of the radiator to the front thereof, and, risingthrough the opening K, pass back to the same point above the partitions G into the top cross-flue, J, and into the top central chamber, F, which has a top central opening, over which the smoke-pipe connects. As the radiator is inclosed by the outer casing or jacket, leaving a space all around the radiator, the cold air entering at the bottom of the jacket rises in the spaces between the concen- 1 of a direct vertical draft from the combustionchamber, andthus allows the use of soft coal,

which is an important matter in a heatingfurnace. The damper is weighted on one side at H, and is thereby made self-closing, while its handle M passes through the radiator just above the feed-door N, and is bent or curved downward in front thereof in such manner that the opening of the feed-door will bring its upper edge against the depending curved handle, and raisin g it thereby open the damp er, As the damper-handle is not attached to the door, the damper can be opened and held open when desired without opening the door.

Instead of weighting the damper, the curved or bent handle thereof may be weighted.

Referring to the draft of the furnace, I propose to make the flues sufficiently large to give the required indirect draft for burning soft coal, while in case of an overcharge of gas-in the combustion-chamber the pressure caused thereby will lift and open the damper by reason of its being pivoted to one side of the center, and thus give a direct draft to relieve the undue pressure is relieved.

The cold-air induction-pipe may be connected with the casing at any suitable point.

The state of the art shows that much has been done in heating-drums for stoves and'in' radiators for hot-air furnaces in which concentric fire-fines receive and discharge the products of combustion, and give out their heat in intervening open spaces for heating air passing through said spaces in contact with the walls of said fire-fines, and my invention does not broadly comprehend such a thing,

but only the matters of improvement to which the claims are specially directed, and which consists, essentially, in using one or more concentric flues, each divided into an upper and a lower communicating passage by a horizontal purpose stated.

I claim 1. The radiator or heater embracing two or more concentric flre-fl'ucs divided horizontally, the vertical central chamber, a damper for dividing said chamber, a cross-flue opening into the lower part of said chamber, communicating with the lower concentric iire-flues at the rear side of said heater, a cross-flue opening into the upper eXit part of said central chamber, communicating with the upper concentric fire-flues, and open air-spaces between the said concentric fire-flues, substantially as described, for the purpose set forth.

IIO

6. The combination, in a radiator, of the central rising and exit chambers, F F, one or more separate concentric fire-flues divided horizontally, and communicating by openings in said divisions, the cross-fines J J, communicating with said separate concentric flues and the said central chambers, and the open air-heating spaces, with a damper dividing the said central chambers, adapted to be opened by the pressure of the gas in the combustion-chamber, and to close automatically upon the relief of said pressure, substantially as described.

7, An air-heater for stoves and furnaces, having one or more separate concentric fireflues divided horizontally, a'central rising and exit chamber, a damper dividing said central chamber in line horizontally with the fire-flue divisions, and one or more open air-heating spaces between the said fire-fines, the latter receiving the products of combustion through an opening in said central rising chamber beneath its dividingdamper and discharging them through an opening in said central exitchamber above said damper, both the receiving and discharging openings being onthe same side of said central chamber, and communicating with the said fire-fines by .openings in their division-plates, substantially as herein set forth.

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