' To all whom 'it ma concern:

' have invented Be it known t at we, FRANK DUPUIS, residing in the city of Pawtucket, in the county of Providence, FREDERICK E. PAGE, residing in the city of Providence, in said county, and GEORGE H. PAGE, residing in the city of Pawtucket, in said county, State' of Rhode Island citizens of the United States, certain new and useful Im provements in Water-Heating Apparatus,

of which the following is a speciication.

The object of our invention is to combine the usual city Water ,system of a building with the usual heating apparatus of said buildi by means of theinterposed device hereina ter specified and thus to provide hot water for cuhnary, domestic and other household uses, and with thisobject in view our invention consists of the novel construction,

combination and arrangement of parts, as

- hereinafter described and claimed. l

\ I 'as seen on line 31..-25. of Fig. 1.

3o tank, and the pipes connected with the saine.

Figs. 4 and 5 are illustrations of an electric Water-heating. apparatus made in accoldance with our invention.

. In the drawings 1 re resents va cylin/denic cast of any suitab e meta and made with one end closed and one end open. The open end. is internally threaded, and a cap 2, having screw-threads on itswed e, fits'in said open end'. The closed end oft ecylinder is tap ed, as shown atf, and the cap 2 is tapped as shown at 4. The cylinder 1, near its open end, is tapped in two laces, one on top shown at'5 and one at the ottoni, shown at 6.

A steam pipe 7 leads froln a steam-heater, or hot-water-heater, or hot-air-furnace, in the cel'lar, or some part of the building, and has a valve 8'. An inlet pipe 9 leads from the valve 8 into the cylinder 1 through the nipple or tap 3..

A returrlpipe 10, connected with the cylinder through-the nipple or tap 6, enters'a valve 11,'and a ipe 12 leads from the valve 11 .to the ra iator or heating system of the building.

A hot Water tankv13 is of usual or anyv preferred construction, and is illustrated in Fig.\3. A pipe 14, connected with the City.

water system, lpasses through the up )er end of the tank am extends nearly to the ottoni of the same. into the tank 13 from the street main atcity pressure. A feed pi e 15 opens from the bottoni of the tank am supplies water by gravity to our improved water heating apparatus.

The feedpipc 1.5 is connected by an elbow 16 with the pipe 17, and the pipe 17 discharges water into the feed-water receptacle 18, which consists of a flattened tube, shown in longitudinal section in Fig. 1, and .in cross section in Fig. 2, having closed ends, which,l however, are tapped as seen at 19 and 20 1n Fig. 1. The pipe 17 enters the feed-water receptacle 1S through the ta 19. Through The pipe 14 dlscharges water the tap 20 of said receptac e 18 extends a pipe 21., which is connected by an elbow 22 with a pipe 23. An elbow 24 connects the .pipe 23 with a'npplc 25, which is secured in The the-threaded opening of the cap 2. inner end of the nipple 25 is connected to the end of a pipe coil 26, which consists of a plurality of parallel pipes, connected b elbows at their contiguous ends, as seen in `ig. 1.

The up )er pipe of the coil 26 passes out lthrough tie closed end of' the cylinder 1,

through/'a tap or nipple there, and is con- .n'ecte by an elbow 27 with the pipe 28, .f'whic'l is connected by an elbow 29 wlth the pipe 30. The pipe 30 enters the T-shaped union 3l from which a pipe' 32 passes throu h the top of the tank, as shown 1n Fic. 2. T el cylinder 1 has at its to an integra pipe 3 3; opening from the cylin er near its o en end, and also near the tap' 3 of the cylin' er atits closed end.- Through the tap or nipple' of the cylinder 1. a pipe'34 extends up'and it is provided with an automatic air valve 35.

The apparatus, thus far described, is adapted to heat water from the steam-boiler, hotwaterfheater, or hot-air-furnace, constitutinthe house-heating system.

he Water from the tank or reservoir 13 supplies our water-heatingapparatus. The water passes through the pipe 15, the elbow 16 and pi e 17, into the receptacle 18, thence throu h tllie pipe 21, elbow 22, pipe 23, elbow 24 an ni ple 25 into the coil 26. The valves 8 and 11 eing open, -the steam or hot water or hot air asses throu h the pipes 7 and 9 into the-cy inder 1, and from the cylinder 1 out through the pipes 10 and 12.

While the steam or hot water or hot air is passing through the cylinder, itsurrounds` pipe 36, elbow 37 andjpipe 38, leading to such aucet or faucets. VAs shown in Fig.. 3, the vpipe 7 connects the valve 8 and pipe 9 with a source of heat 58, which may be a dome or chamber of a steam boiler, water boiler, o1' hot air furnace. Y

To adapt our improved water-heating device to heat derived from a gas burner, instead of a house-heating system, we provide a gas burner 39, having a lurality of gas jets 40. A gas pipe 41 con ucts gas from the street main, or other source, through the l The-'pipe 9 is tapped, as shown at 44, and a pipe' 45 threaded therein. A valve 46 connects the pipe 45 .with a ipe 47. The burner 39 conducts cold water groin the street main under A city pressure. The valve 42 has a lever ior handle 48 to operate thesame, and a'valve 46 has a lever. 49 to operate the same. A'link 50 is pivoted at one end to the lever 48, and at its opposite end to the lever 49. A pipe 45 is connected to the valve 46 and pipe 9.

`A case 51 is made of a casting of com osition consisting of asbestos and PortlanY `ce- Y ment, or other suitable material. This case has an o en bottom, four vertical'sides and a top, w lich is semicircular in cross section.

One edge of the to of this case is longitudinally enlarged an( grooved, as indicated at 52, and one longitudinal edge is inserted into the rroove 52' and secured therein by an suitable means. The case 51 is perora'te( as shown in Fig. 1 forY the passage of the pipes 9, `17, 28 and 34. l

To heat water by means of ourapparatus, when the heat is to be derived from gas, the valves 8 and 11 must bc closed. The water passes, as before described, through the ipes 15 and 28 and the intermediate pipe/coi and .pipe connections. By operatin r the handle 48, both the water valve 46 and t 1e gas valve 42 are `turned. (lold water passes through the pipes 47, a'nd 9 into the cylinder 1 and iillsthe same. The gas is ignited at the jets 40. As the feed-water receptacle 18 is im- 60 mediately above the gas jets 40 and is a flatltened tube having a comparatively large horizontal area on lts. under side, ex osed to the direct llames of the gas jets 40, t e water assing through it is subjected to intense 65.A eat. The heat of these gas flames also fills When l valve 42 and pipe 43 to the gas burner 39.

the interior of the case 51, and quickly heats the entire exterior surface of the cylinder 1, and .the watercontained in the cylinder 1 is raised to a high temperature. As the water in the 4cylinder ,1, which is at first cold (being 70 introduced directly from thestreet mains) a circulation is set up therein, as soon as the gas ets 40 are li ,hted.

T e water in vhe cylinder 1 which is the most heated-rises and Hows through' the pipe 75 33, as indicated by the arrow 53,' and is dls.- chargedtherefroni into-the cylinder 1- near the inner end of the pipe 9. Thus the water in the rece tacle 18 is heated by the di ect action of t 1e burning gas jets and th ce lle flows up through the p1 e coil 26 and out through the pipe 28 to t e tank 13, and at the same time the water while passin Y through the pipe coil 26 is brought to a sti higher temperature by the heated water se within the cylinder 1 in contact with the exterior surfaces of said pipe coil throughout its entire extent. YVhen the gas valve 42 is closed by turning the lever or handle 48, the link 50, by moving the lever .49, causes theao water valve 46 to close, thereby shutting oii" the water from the street main. The/water may be discharged from the cylinder 1, when convenient,by opening the valve 11, the air. valve 35 facilitating such discharge. ,95

In Figs. 4 `and 5 we show anim roved Water heating apparatus provide( with means of electric heating. In said figures 54 representsv an electromagnetic coil, having a. core 55, passing'throughrit. The c oil.54 is 10o supporte( beneath the cylinder 1 by the core, 55, the two poles or ends of the latter extendingup vertically into the cylinder 1. On the upper ends or poles of the core, respectively, are the radiating plates 56. The electric switch board is shown at 57 and wires 58 co'nnect the coil 54 with a source of electricity; To heat water in our improved apparatus by means of electricity, the valves 8 and 11 are closed and the valve 46 is opened. Water 110 iiows from the street main through thepipes 47, 45, and fills the cylinder 1, as shown in` Fig. 5. By operating the switch 5,7, electricity is turned on and energizes the electromagnetic coil 54 and the core 55, and the ra- 115 dieting plates 56 are thus heated. As the )lates 56 are surrounded by Water in the .cylinder 1, as represented in Fig. 5, the water is heated from said plates, and. the wat-fr n the coil 26, which ci'iters throughjthe pipes `15, 120 171, and is discharged through the plpe 28, receives its heat from the water outside the coil inthe cylinder 1.

By means of this improved apparatus it is ossible during the winter to supply the iouse withhot water heated from the steamboiler, hot-water-heater, or hot-air-furnace of the usual house-heatinv4F system, and in summer to supply water lheated by a .gas burner or by an e ectric coil.
