Application September 28, 1934, Serial No. 745,841 6 Claims. (Cl. 257-254) l. The invention relates to water heaters and particularly to utilizing a conventional range boiler as a unit part of the heater or, in other ' words, associating the water heater and heating medium employed with a boiler of the class de scribed, and the object of the invention is to provide a water heating unit employing a range boiler with a heating coil associated with and arranged beneath the boiler, with a source of heat supply disposed immediately below the heat er coil, whereby the products of combustion radi ating from the heating medium may be directed first onto the coil and then upon the boiler; a further object being to provide a water heating member or coil comprising a series of tubes open at one end, each tube containing a baffle or par tition plate forming circulating passages within - rthe tubes and detachable plugs at the open ends of the tubes, facilitating the removal of the plates and the cleaning of the tubes and plates whenever desired; and with these and other ob -jects in View, the invention consists in a heater unit of the class and for the purpose specified, which is simple in construction, eilîcient in use, and which is constructed as hereinafter described and claimed. The invention is fully disclosed in the following specification, of which the accompanying draw ing forms a part, in which the separate parts .of my improvement are designated by suitable reference characters in each of the views, and »in which: Fig. 1 is a side and sectional view of the unit made according to my invention with part of the .35 construction broken away. Fig. 2 is a partial section on the line 2-2 of Fig. 1. Fig. 3 is a partial section on the line 3-3 of Fig. k2. ` Fig. 4 is a detail plan and sectional view of a modified form of heater which I may employ, and, ' Fig. 45 is a perspective view of one of the baille plates which I employ. `In Fig. 1 of the drawing, I have indicated at I0 yairange boiler or hot water tank of more or less conventional form supported on a stand II provided at its upper end with a flanged ring I2 upon which the boiler or tank seats. The water supply and discharge tubes to the tank or boiler are not shown but these will be of the conven tional or any desired arrangement. But, at I3 I yhave shown the usual drain pipe extending from ` the bottom wall of the boiler, which pipe is pro vided with a usual Valve or shut-off, not shown. . At I4, I have shown the cold water circulating pipe extending from the lower portion of the boiler I0, and connected, asi indicated at I5, with my improved water heater I6, a union Illa being incorporated in the pipe I4 to facilitate the 55 mounting of the water heater as will be apparent. The water is discharged from the heater I5 through a pipe I'I which couples with a fourway coupling I3 with which the hot Water supply pipe I9 is also coupled, the latter extending to and lo being connected with the upper end of the boiler as indicated at 20. Clean out plugs I8a are pro vided on the coupling I8 to facilitate cleaning out the pipes I'I and I9. In the construction shown I employ a skirt or jacket portion 2 I which extends downwardly from the ring I2 and envelops the stand II, water heater I6, as well as the gas burner 22, or other heating medium or source of heat supply. In other words, `the skirt or jacket 2E forms what might be termed a heater casing which is posi tioned directly below the boiler I9. The burner 22 is supported on transverse straps 23 and the rear end of the water heater I6 is supported on a transverse strap or rod 24, the forward end,A being supported by the pipes I4 and I9 and the y connections thereof. At the lower portion of the skirt 2l are a number of air inlet openings 25 for supply to the burner 22. At one side of the skirt or casing adjacent the lower end of Í the boiler is an elbow exhaust 26 for the dis charge of products of combustion from the cham ber 2 la within the skirt 2l. The water heater I6 as shown in Figs. 1 to 3 in clusive consists of a casing 2l having one longi- ¿2. tudinal passage 2S extending therethrough, and three transverse passages 29, 36, and 3|, the for ward ends of which are cloœd by plugs 29a, 39a, and Sla, and coupled with the rear ends thereof are elongated thimble shaped tubes 32, 33, ande' 34. In each of these tubes are arranged baille or partition walls 35, 35, and 3l', the forward end portions of which are provided with laterally ex tending ears 38 which set in slots 39 formed in the casing 2'! at the inner end of the plugs 29a, 39a, and 3Ia, so as to position the baffle plates 35, 36, and 3l in the diagonal arrangement illus trated clearly in Fig. 3 of the drawing to provide at the lower side of the circulating tubes 32, 33, and 34, passages 40 and at the upper portions thereof, passages 4I placed in connection at the rear closed .ends of the tubes 32, 33, and 34 as in dicated at 42, the latter being formed by project ing stop pins or fingers ¿I3 at the inner ends of the plates 35, 3E, and 3l. In Fig. 5 of the drawing 2 2,029,927 I have shown a detail view of the baii‘le plate 35 be applicable for use as a household heater or on an enlarged scale clearly illustrating the ears built on a larger scale to satisfy greater volume 38 and the ringer 43. of supply and still further may be used for com mercial purposes. But, in all cases the funda , In other words, in the construction shown in Figs. 1 to 3 inclusive the heater I6 is made up into three tubes, each subdivided by a baii‘le or parti tion plate to divide the same into what may be termed intake passages 4Q and exhaust passages 4I placed in communication at the inner ends of 10 the tube as at 42 so that cold water entering mental plan of the unit will be carried out. Having fully described my invention, what I claim as new and desire to secure by Letters Pat ent, is: l. A heat exchanger device comprising a casing having a continuous bore extending longitudinally 10 through the pipe I5 will ñrst pass into the bore therethrough, a plurality of tubes radiating from 28 below the plate 35, ño-w backwardly through said bore at spaced intervals longitudinally there of, the chambers of said tubes opening into and the passage 40 and then forwardly through the passage 4I in the tube 32, again into the bore 28 15 beneath the plate 35, pass successively through the tubes 33 and 34 in the same manner, and being in communication through said bore, means arranged longitudinally of said tubes and ex tending through said bore for subdividing the ñnally discharge through the pipe I'I from which tubes into independent circulating passages placed it will pass into the pipe I9 and thus into the boiler III. In other words, the circulation be 20 comes continuous when the burner 22 is in op eration to circulate water'from the bottom of the boiler back and forth through the tubes of the heater I6 and to the tube of the boiler. From in communication with each other at the free end of the tubes said last named means comprising plates, and the casing having spaced passages in ~ alinement with said tubes and communicating with the bore of said casing to provide attachment time to time, and especially in using heater units 25 o-f this type with certain types of water supplies, tubes. ing having a continuous bore extending longi _in the pipes, tubes, and the like of the heater unit and the circulating pipes of the system. For this reason, the plugs 29a, 38a, and 3io: are em tudinally therethrough, a plurality of tubes ra and 31 to clean off said plates as well as the 40 45 50 tubes 32, 33, and 34. The plugs [email protected] may also be removed to clean out the longitudinal passage or bore 28, the pipe I'l and the pipe I9, thus keep ing the circulating system absolutely clean at all times and in like manner maintaining the most eñ‘icient heating exchange between the burner 22 or other heating mediums employed and the Walls of the tubes of the burner. It will be understood that instead of arranging the member I6 in a straight horizontal plane as indicated in Fig. 1 the same may be disposed in an inclined plane with the end attached to the pipe I1 higher than the end attached at the pipe I5 to increase circulation. In Fig. 4 of the drawing I have shown a slight modification of the structure shown in Figs. 1 to 3 inclusive wherein the water heater |611 has its 4tubes 32a, 33a, and 34a., cast or otherwise formed integral with the casing 21a and aside from this structural change the heater IGa is the same as ‘the heater I6 and operates in the same manner. It will also be seen upon consideration of Fig. 2 'of the drawing that a cover 44 may be formed 55 on the casing or skirt 2| in alinement with the plugs 29a, 39a, and 3Ia to give access thereto Vwhenever desired, the cover being hinged as is indicated at 45. By constructing a water heating unit in con 60 junction with a boiler or other storage tank in diating from said bore at spaced intervals longi tudinally thereof, the chambers of said tubes opening into and being in communication through said bore, means arranged longitudinally of said tubes and extending through said bore for sub dividing the tubes into independent circulating passages placed in communication with each other at the free end of the tubes, said last named means comprising plates, the casing having spaced pas sages in alinement with said tubes and communi cating with the bore of said casing to provide attachment and detachment of the plates with respect to said tubes, plugs detachable from the 40 casing -for closing each of said passages, and means on the plates and in said casing for keying the plates against rotation in the casing and said tubes. 3.
