Application filed April 7, 1909. Serial No. 488,453. a

To all whom it may concern;

Be it known that I, WALTER W.

residing at Putnam, in the county of Windham and v scribed and State of Connecticut. have invented certainnew and useful Improvements 1n Water- Heatlng in to the accompanying drawing.

This invention relates to improvements in systems or apparatus for heating water more particularly for household purposes, and has for its object to provide a simple, practical and inexpensive means whereby the water service pipe may be connected directly tothe steam heater and run into and through one or more of the water chambers thereof and upon emerging from the upper portion of the heater return to the usual hot Water supplying tank.

It is customary in many instances to use a gas range in the kitchen, in which case it 1s rather expensive to heatthe Water for the usual hot water tank. Then again, when the coal or gas range is alone used to heat the tank, as soon as the fire is low or out the water becomes cool and there is' no hot water for bathing or other purposes during the evening. In some instances a heating system has been connected to the tank in which a coil for heating the water is placed over the fire-pot of the heater to come in direct contact with the heated gases, but by this system the water'is often boiled and converted into steam creating a pressure which sometimes if not properly vented is likely to explode. Then again, the coil being in such close contact with the fire burns out quickly and is obliged to be often renewed.

My improved system of running the service pipe through a water chamber of the boiler 1s found to heat the water in the pipe to the desired temperature and as the heat thus applied to the pipe is mild compared to the heat in the fire-pot, the life of the pipes and fittings of this system are prolonged indefinitely.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fullydeparticularlypointed out in the ap ended claims.

n the accompanying drawings: Figure 1,- is a diagrammatic view illustrating the hot water supply tank as being connected Apparatus, of. which the following- 1s a specification, reference belng had therea .in which is fit-te to the water front in the range, and also to the heater located in the basement. 9 is an enlarged detail of the steam heater partially in section showing the detailed arrangement for attaching the hot-water serv-- ice pipe thereto for heating the water for household purposes.

Referring to the drawings, 1 designates the usual steam heater for heating the building in which the same is located, and 2 represents the usual hot Water supplying tank to which this heater may be connected through the service pipes 3 and 4.

One style of heater to which my system may' be attached is made up of a plurality of superimposed hollow water retaining sections, the whole being suitably connected so that the hollow portions in each of these sect-lons communicate one with the other, said communication-being by way of the upright water leg or chamber 5 through the ports 6, 7 8 and 9, as illustrated in Fig. 2. These water legs or chambers 5 are preferably formed by extending the heater casing out on either side in a semi-tubular form beyond Fig.

the regular circular contour of the body of casing the heater proper, which projecting place throng which provides a convenient to pass the hot water 1pc. The simplest and -most convenientorm of makln connection to this casing is byta ping out 1ts lower end at 10 and screwing t erein a bushing 11. This bushing is tapped from its lower side to receive the nipple 12 and from its upper side to receive the service pipe 13, which pipe is preferably constructed of brass and is passed down through the upper end of the casing, said end being. also (provided with a bushing 14 a packin gland 15 through which this ipe is passe and madetight,

circulating or service the gland a so allowing for a slight movement' of said pipe due to the uneven expansion of the dlfierent metals. By inserting this service pipe into the water chamber of the heater proper this pipe receives the 'di-- rect elfect of the hottest water in the heater which is constantly surging around it.

Vvhenit is desired to have the hot waterfront or coil 16 in the kitchen range, indicated inoutline at 17, see Fig. 1, to operate in combination with the steam heater 1, it is only necessary to connect the same y means of pipes 18 and 19 to pipes 3 and 4., and the two will work in unison, and a valve 20 may ing apparatus tions, sai an outwardly projecting semi-tubular up:

be inserted into pi 4 to cut oil the supply from the heater, i desired when the water in the tank has become suificiently hot.

By the arrangement of my improved heat- I am enabled to obviate the necessity of expensive auxiliary heating devices or apparatus and provide simpl.e, practical and inexpensive means for readily attaching the system. direct to .the .heater whereby a portion of the service pipe may come in direct contact with thehottest portion of the circulating water in the heater thereby obtaining the maximum efiiciency with the minimum expenditure of heat.

Having thus described my invention, what I'claim as new and desire to secure by Letters Patent, is:

v 1. 'In an apparatus of the character de-- scribed, a heater constructed of a casing. and

a plurality of hollow water containing secheater casingbeing formed with ri ht water leg-which extends along one side 0 the casing, there being a series. of ports which establish communication between said water leg and said sections, a pipe extending l through said water leg, and a service pipe connected to each end of said water leg.

2. In an apparatus of the character described, a heater constructed of a casing and a pluralitly tions, sai heater casing being formed with an outwardly projecting semi-tubular u right water leg which extends along one si e ofthe casing, there being a series of ports which est blish communication between said a water leg and said sections, a bushing tapped into the top end and a bushing tapped into the bottom end of said water leg, a pipe extendingithrou h the top bushing and having its lower en threaded into said bottom bushing, a nipple threaded into the under side of the bottom bushing, a packing gland carried by the top bushing, and service pipes connected to the nipple and the upper end of thewater leg pipe.
