This invention relates to at hot water heat or or furnace and is applicable to furnish a supply of hot water steam or vapor wherever needed, pzwticulcrly to the radiator in a hot water steam or vapor hosting system.

It is on object of this invention to provide such e heater or furnace comprising super mg central passages therethrone coznmuni outing with said hollow arms; the hollow rings, arms and central passage forming water chambers.

lit is still another object or the invention. to have a heater or furnace composed of such superposed sections with gas passages therethrough, in combination with means at the top and bottom of the heater or furnace to regulate such gas passages.

These and other objects end. advantages of the invention will more fully appear from the following description mode in connection with the cccompanying drawings in which like reference characters refer to the same parts throughout the difierent views, end in which Fig. 1 is :1. vertical section through the device token substantially on the line 1-l of llio" 2- Fig. 2 is c horizontal section taken on the line 2--2 o1t Fig. l; I I

Referring to the drawings, the devicecpnn prises a. hollow or shell-l-ike trusts-conical base frame 1, having concentric ribs l and 1* at its top provided with ennnlcr grooves therein. A flange, 1" extends 'hmween the slot formed through said sections,

bottom of the ribs 1 end .1 which is provided with circuinterentiully spaced spertures .l An annular piste 2 rests upon the flange 1 and is adopted to be rotated between the rilos 1 and l and on ssid fienge, which plate is provided wii e laterally projecting handle 2" which projects throu h a in the outer rib l by means or w 'ch handle the plate 2 is rotated. Plate 2 is also provided with circumferentielly spaced openings 52* which may be brought into or out of slinement with the opening l in the flange 1. Supported upon the ribs 1 end 1 are a plurality of superposed circular sections 3, one of which is shown in plan in Fig. 3. The sections 3 are of considerable vertical extent undhsve cooperating ennuler tongues and grooves on their respective horizontul sides, so that the sections fit together in superposed relation, as clearly shown in Fig. l. Said sections 3 comprise spaced hollow rings 3 end 3" which are con nected by radially extending hollow arms 3 end 3, respectively. The spaces between the rings 3 and 3 and the arms 3 and 3 form vertical openings i and 5 through the sections 3 and other vertical passeges 3 are being surrounded with suitsble wells extending be tween the top and bottom of said section. The sections 3 also have at central pessege therethrough preferably oi cylindrical.- shepe, as illustrated, with which the inner ends of the hollow srins 3 coinincniccte, the open inner ends of said-arms forming vertical slots 3, as shown in Figsxl end 3. The various memhersor sections 3 ere arranged in seid superposed relation with the openings 3, d and 5 in vertical slinement, so that vertical passages are formed extending from the lower section to the top section 3, as shown in Fig. l. The central pesszige of the lowest section 3 is closed, as shown. at 6 and it will be seen that the plate 3 end flange 1 are disposed directly below the vertical passages formed by the openings 3 and 5. The top section 7 rests upon the upperrhost section 3, losing provided in its lower side with concentric tongues'fitting in the concentric grooves in said upperunost section. 3 and said section 7 is provided with at central chamber 7", the top of which is closed and said chamber is connected by radial arms 7 to an outer ring 7, which ring 7 has vertical gas passages 7 therethroughsimiler to and elined with the gas Ell til

passages 3 Circumferentially spaced gas passagesare thus formed between the ring 7 to the chamber 7 and the arms 7. An annular flange 7 upstands from the top of chamber 7 and an annular plate 8 rests upon the top of section 7 having a central opening fitting about the flange 7 which plate is thus rotatable on section 7 and about said flange. The plate 8 is provided with circumferentially spaced sector-shaped open-- ings 8 adapted to be broughtinto or out of alinen'ient with the openings between the arms 7 and said plate is provided with an operating handle 8 projecting through a slot in an upwardly projecting rib 7 extending around the upper and outer edge of section 7. A top dome-shaped member 9 has an annular tongue at its bottom edge adapted to lit in the groove in rib 7, the outer surface of said top being flush with the outer surface of section 7 and the sections 3. The top 9 is contracted at its upper central portion to form a conduit adapted to be connected to the chimney. An inlet pipe 10 for water is connected to the outer wall of the lowermost section 3 and an outlet pipe 11 for water is connected to the outer wall of the section '7.

Ar. intermediate section 13 is provided similar in all respects, to the sections 3, except that it docs not have the openings 3 into the central passage thereof and inlet and outlet pipes 14: and 15, respectively, connect with the. outer wall of said section 13 at opposite sides thereof. The sections 3, 7 and 13 are connected at their central ortions by sleeves 16 which project at t eir ends some distance into the adjacentcentral portions of the said sections. The sleeves 16 are slightly tapered at their ends, as shown at 16 in Flg. 6 and are dr1ven into the central portions of the various sections so that the sections are connected and a continuous passage is formed centrally thereof from the bottom wall 6 to the top of chamber 7". burner 17 for gas, oil or other suitable fuel is disposed immediately below the center of the lowermost section 3 and its wall 6. Said burner will he su plied with fuel by conduit 18 adapted to is connected to a suitable fuel supply.

In operation, the inlet and outlet pipes 10 and 11 will be connected to the device to which the heated water is supplied, such as the radiators of a hot water system and said inlet pipe 10 will also be connected to a water supply system not shown. ,VVater will enter pipe 10 and flow into the outermost ring or" the lowermost section 3 around the passages 3 thcrethrough, will pass through the arms 3 into ring 3 and through arms 3", slots 3 into the central chamber of the section. Said. water will rise through the central. chamber and flow out through the sl ts of the next section into the various massacwater chambers therein. The Water chainbers of all of the sections will thus be filled. The burner 17 being lighted and the plates 2 and 8 being turned to close the passages through flange 1 and between arms 7, the

'heated air and products of combustion will pass upwardly through the alined space 4- of the sections, as indicated by the lower arrows in Fig. 1., and this air will then pass downwardly through the passage formed by the alined openings 5 and will then return, as indicated by the outer lower arrows in Fig. 1, up through the passage formed by the alined openings 3*, said heated air and products of combustion then being considerably cooled in passing out through the top of the member 9. The water in the various sections will thus be heated and will rise through the various sections through the central passages thereo'i through the slots 3 so that the heated Water will pass out of the outlet 11 to the radiators. 'lhe returning cooled water will return through inlet pipe 10 to again circulate through the device. it will be understood, of course,.that the connection to the Water supply will be turned oii' as soon as the heater is suitably supplied with water. When a strong draft is desired, as when starting a lire, one or both of the plates 2 and 8 may be revolved to bring the openings therein in register with the open-- ing's through the flange 1 or between the arms 7, respectively, so that a free passage for the air and products of combus tion. will then be effected directly through the yarious alined gas passages s 5 and 3". After the fire is well under way and the furnace or heater brought to the proper temperature, the gas passages may be controlled as desired by rotating the 2 arid 8. a

It will lie-noted that the 13 is not connected into the circulating 5 item by the slots 3. This section is prvided to furnish a supply of hot water r the purpose of household and domestic use. it is de sired to have this Water clean at all times and the inlet and outlet pipes let 15, respectively, will be connected in a domestic water supply line so that ho water may be drawn from section 13 through the pipe 1-5 when desired, said hot water being replaced by water running through pipe 14.

From the above description it i masses It will, of course, be understood, that various changes may be made in the form, details, arrangement and pro ortions of the parts without departing rom the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, such as shown and described and set forth in the appended claims.
