GAS-FURNACE.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed August 24, 1911. Serial No. 645,728.

To all whom it may concern:

Be it known that I, EDGAR H. TRo'rrnR, a citizen of the United States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented a new and Improved Gas-Furnace, of which the following is a full, clear, and exact description.

My invention relates to a new and improved form of gas furnace, and an object of my invention is to provide a furnace having relatively large radiating surfaces. in proportion to the fire zone.

' A further object of my invention is to provide a furn ce in which the heated air is rapidly and e onomically conveyed away from the furnace through the heat-carrying iron jacket of conventional configuration.

With the above and other objects in View, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustratedin the accompanying drawings and more particularly pointedout in the appended claims. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure 1 is a vertical transverse sectional view partly in elevation, showing a pre-- ferred embodiment of my invention; Fi 2 is a horizontal cross sectional view ta en on the line 2-2 of Fig. 1 and looking in the direction of the arrow; and Fig. 3 is a trans verse sectional view taken on the line- 33 of Fig. 1,.looking down on'the device.

Described more in detail, the device consists ofa vertically disposed radiator 4 supported some material distance off the ound by means of feet 5, which radiator 15 of a general corrugated construction, which corrugations are formed by radially disposed rectangular boxes 6, forming between them vertically-disposed V-shaped flues 7. The radiator is closed at the bottom with the exception of V-shaped air inlets 8 disposed at the point of each box where it joins the main portion-of, the radiator. Centrally disposed in the bottom of the radiator is a cylindrical burner 9 having apertures 10 extending therethrough, which burner is supplied with gas'or other combustible fluid through a pipe connection 11.

Resting upon the burner 9, which extends, as shown in the illustration, less than half the height of the radiator, is a metallic cylinder 12 having a conical lower end 13, so that the lower end of the cylinder will conform to and fit the top of the burner, and the upper end of the cylinder will be of materially greater cross sectional area than said burner. This cylinder is filled, as shown at 14, with sand, ashes, asbestos, or other suitable heat-retaining substance. Positioned on top of the cylinder 12 and pro ecting through an opening at the top of the radiator, is a; cylinder 15 having a nipple 16 centrally disposed thereon and extending upwardly therefrom, and having a series of side apertures 17, by means of which the products of combustion from the burner may pass therethrough and through the bore 18 of the nipple l6, out through the smoke'pipe 19.

In order to afford a deflecting surface for the heated air passing through the heating pipes 20 hereinafter described, and at the same time, to afl'ord a radiating surface to utilize the heat from the products of combustion, a funnel 21 engages the nipple 16, the side of said funnel being in alinement with the heating pipes 20. The top of the funnel is closed by means of a plate22, and disposed within the funnel is a floor 23, between which floor and said plate is disposed a layerof sand or' other insulating material 24.

plate 22 and floor 23 and terminates within the funnel 21. Extendin radially from the side of the lower end 0% the smoke pipe 19, is a series of small pipes 25, the outer end 26 of each of which. is adjacent the wall of the funnel 21. It will beseen that by The lower end of the smokeplpe 19 1s closed'and passes through the this construction, the heated products of combustion pass throu h the bore 18, and in order to pass throug the smoke pipe '19, they spread out contacting with the walls of the funnel 21, heating said walls so that 7 through the which pipe 19.

these walls will act to conduct the heat same, to heat the air passing through the flues 7, and at the same time deflect the heated air into the heating pipes 20.

The radiator and funnel are inclosed in I the customary form of sheet iron jacket 27, which jacket is of a materially greater crosssectional area than the radiator 4 so as to permit -a relatively large air-heating space 28. Leading from the jacket at the upper end thereof, are the heat pipes 20, in substantially horizontal alinement with the funnel 21-. This sheet iron jacket is capped by means of a closure 29, extending through is the vertical portion 30 of the While a preferred embodiment-of the invention has been described, it is to be understood that many changes could be made in the above construction and many apparently widely different embodiments of this invention couldbemadc without departing from the scope thereof. It is intended that all matters contained herein in the above description' or shown in the accompanying drawings,shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims isintended to cover the full scope of the invention and is not to be given any narrower construction than the prior art demands, and that materials, sizes Having the corrugations of said heat will be directly radiated from said burner and said receptacle into said corrugations.

2. In a hot air furnace, a vertically disposed and vertically corrugated radiator, a

s burner disposed in the lower portion of said radiator, a receptacle positioned on said burner, said receptacle having a heatretaining substance therein, the interior of the corrugations of said radiator facing said whereby the heat burner and said receptacle, will be directly radiated from said burner and said receptacle into said corrugations, and means for conveying the products of combustion from said radiator.

3. a hot air furnace, -a acket having heat conveying pipes at its upper end, a

- vertically disposed radiator in the jacket and'having an outlet at its top and'provided with radial boxes forming between them vertical V-shaped flues, a burner in the radiator, a funnel secured over the outlet I of the radiator and opposite the heat conveying pipes and receiving the products of combustion from the burner, and a smoke pipe leading from said funnel.

4. In a heat conveying pipes at its upper end, a radiator within the jacket and having an outlet at its top,'a burner arranged in the radiator, a funnel arranged opposite the heat conveying pipes and into which the hot air furnace, a jacket havingproducts of combustion from said outlet are f discharged, and a smoke pipe having a closed inner end projecting into the funnel and provided with lateral openings:

5. In a hot air furnace, a jacket having heat pipes extending outward from its upper end, a radiator within said jacket,-a burner within said radiator, member carried by said radiator and in communication therewith and disposed opposite said heat pipes, and a smoke pipe having one end terminating within said funnelshaped member, said pipe having 'radiallydisposed pipes in communication therewith and extending to the side of said funnelshaped member, whereby the heated products of combustion from said burner will be brou ht in contact with the side of'said funnel-s aped member before they can escape through the heat ing the side of said 6. In a furnace, a having closed end projecting into said member centrally through said closed top, and a series of pipes within said member adjacent said top, having one end of eacheopenin into the side of said pipe, and the other en opening funnel-shaped member side of the wall thereof.

7. A hot air furnace comprising a jacket having heat conveying pipes at its upper end,a radiator in the jacket, a burnerin the radiator, a cylinder above the burner and containing a heat. retaining substance, an apertured chamber above the cylinder and having a nipple projecting through the radiator, a funnel on said nipple and opposite the heat conveying pipes, and a smoke pipe leading from the funnel.

In testimony whereof I name to this specification in the presence of two subscribing witnesses.
