Tliis invention relates to improvements upon old style cast iron heating boilers, either steam or hot water system.

`The principal object isto generally imo' prove vupon structures of .this class vby providing one of simplicity, one lwhich is sub- Lstantial and durableeasily constructed, and otherwise efficient in construction and operf ation. l' f One of the specific objects of the invention is to provide a boiler which 'will be economical in the consumption of fuel, or in other words, capable of'utilizing, to the very fullest extent, 'the heat produced by thecombustion of the fuel, which may be either oil, gas

or coal,jwhile at the same time, not complicating the construction, and rendering it capable of easy cleaning and repairing. The particular details and novel organiza# tion thereof will become more'readily apparent from the following description and drawlngs. Y-

In the drawings Y l l v Figure 1 is a front view of the complete 555 assembly-with portions lbroken away to disclose internal structure. Y.

Figure 2 is a side view, with portions broken away and shown in section.

Figure 3 is an enlarged fragmentary sec- Sc tional and elevational view showing a special spray nozzle and mounting therefor.

lFigure 4 is aview similar to Figure 3, showing a special intake water fitting, and mounting therefor.y

Figure 5 is a cross section through one of the copper tubes.

Referring now to the drawings in detail, it will be seen that the reference character 1 designates the base which is of general rec- 19 tangular configuration and which isin the form of a shell, having an appropriate interior lining 2, forming the wall of the fire box. On one side is an entrance opening 3, by means of which access is had to the inte,-

rior of the fire box, for placement of the burner. kAbove this is a peep hole 4, to permit the interior of the fire box to be clearly observed ,from time to time to ascertain operating condition of the burner. On one or both sides (see Figure 2) are hingedly mounted doors 5, which operate as safety appliances, and which swing open in the event that an unusual and dangerous'pressure is formed Within the yfire box. Seated on the base is a boiler.` proper generally desig- .i

hated by the reference character 6. This comprises awater jacket including inner and outer lspaced parallel walls 7 and 8 respectively, adapted to provide the space 9 therebetween. For convenience the lwall 1() is designated' as the boilerhead. Also the reference characters 11 are employed to designate Yspecial boxes at the bottom fof ,the boiler.

Formed onV the top ofthe boiler at Yopposite sides are similarv domes 12 of general eloni gated ovateconfiguration. Located between these `is a smoke hood13, which is incommunication with the smoke lues 1 4, which are connected with thehead wall and the top wall. A stack pipe 15 is connected with the T hood 13, 'for conduct-ing the` particles of smoke to the-chimney. Steam mains v16 are connected with the respective steam domes 12. Also mounted on 'one of the steam 'domes is a safetygvalve 17 `and mounted on the other one is a pressuregage' 18. Then, too, a level gagel 19fis provided on one side ofthe boiler. Connected to the opposite side ofthe boiler is'the feedwater pipe 20 and cold water return .pipes-21. Particular emphasis is'to be laid uponthe construction of the water circulating and heating tubes, one of which is generally designated by the reference charac- /ter22. Incidentally'the tube is formed of copper and is of the oval cross sectional shape indicated inFigu're 5, in order to provide a greater heating surface. As isl customary,k

the tube isformedof a plurality ofbent coils,

horizontally ydisposed.-- It will be noticed,`

however, that-the adjacent coils are bentinto zig-zag formation, as indicatedy in Figure 2.

The individual coi-ls are. designated by the reference characters 23..

The intake end of the lowermostcoils 23 (see Figure 4) is connected with 'the special fitting, and anchoring element 24. This comprises a casting, having an appropriate connection 25 having a flat top 26'and arestricted intake 27. Thefintake 27 extends dovvn through` an opening Vin the adjacent Wall of MPATENTf-FFICE the box 11 for communication with the water space 9. An elongated angle iron 2S is provided, and the vertical flange bears upon the box l1, while the horizontal flange bears upon the flattened top 26 of the fitting 24. The iron is bolted in place by bolts 29. Referring to the discharge end of the uppermost coil, as shown in Figure 3, it will be observed that this connects with a constricted discharge nozzle 30. The nozzle is of elongated tapered form, terminates in a bevelled end 31 and.

has a flattened head 32, at the opposite end. Again, an angle iron 33 is provided here to hold the nozzle in place, and the iron is secured in place by boltsBL.

Itwill be observed that the zigzag disposition of the circular coils in the circulating` tubes provides proper clearance so as to allow the heat and fumes to pass between the tubes to the flues, without undue obstruction. The tubes are connected alternately to both sides of the water jacket, the discharge. end being connected to the top of the boiler, at the same side the cold water is taken out. The next circulating tube is connected to the opposite side and returns to that side. In other words, the discharge and intake of each circulating tube is connected to the same side of the boiler, while the corresponding-portions of the next or adjacent tube are connected to the opposite side of the boiler, thus providing the desired alternate arrangement. The special means comprising the angle irons for holding the fittings and nozzles in place is of exceptional importance, for When it becomes necessary to remove a damaged tube, this can be done without'interferring with the adj acent tubes. The 45 angle cut on-the discharge ends of the nozzles is important in that it serves to sway the steam against the side of the jacket. By doing this it produces a drier steam. The water jacket isformed from steel plates made'of proper shape and electrically welded together. y'Ihe arrangement of smoke flues is such as to attract the heat to the sides of the boiler, rendering the tubes on'either side more efficient in operation.

It is believed that by carefully considering end of the tube communicating with the water jacket, a discharge nozzle on the discharge end of the tube also communicating with said water jacket, removable angle irons bolted to the boiler and holding said fitting and nozzle respectively, whereby to permit bodily removal of the tube, said fitting comprising a hollow cast body, having a tube connection and a flattened end cooperable with the complemental flange of the adjacent angle iron, said discharge nozzle having a bevelled extremity and also having a flattened head portion cooperable with the complemental fiange of the adjacent retaining iron.

2. In a boiler structure of the class described, spaced walls defining a vwater circulating jacket, a circulating tube of coiled formation supported in the boiler, a tapered fitting on the intake end of the tube extending through an opening in the adjacent wall into the water circulating space of said jacket, said fitting having a flattened end portion, a removable angle iron bolted to said last-named wall and having one flange positioned for engaging the flat head ofl said fitting to force the tapered end portion into the water space and to hold the fitting in place, a discharge nozzle on the discharge end of the tube, extending through an opening in a complemental wall, said nozzle being of tapered design, having a beveled discharge extremity and having a attened end portion at its opposite end, a complemental retaining iron fastened to the last-named wall to engage and hold the flattened head portion of the nozzle, whereby to Aprovide a structure permitting bodily removal of said circulating tube, fitting, and nozzle. VIn testimony whereof I aliix my signature.

the detailed description in connection with Y the drawing, a clear understandingk of the construction, assembly and operation of the invention will be had. Therefore a more lengthy descriptionis believed unnecessary.

ll/Vhile the preferred embodiment of the invention has been shown and described, it is to vbe understood that-minor changes in shape,

size and arrangement of parts may be resorted to, if desired.
