HENRY POWELL, OF NEW YORK, `N. Y.
WATER-HEATER.
SPECIFICATION forming part of Letters Patent No. 729,793, dated June 2, 1903.
Application filed July 8, 1902. Serial No. 114.734. (No model.)
To @ZZ whom, t may concern,.-
Be it known that LHENRY S. POWELL, a citizen of the United States, residing in the city of New York, county and State of NewA York, have invented anew and useful Improvement in Water-Heaters, of which the following is a specification. y
My invention relates to improvements in water-he aters in which steam-pipes or a steamcoil is mounted withinl a water receptacle, which receptacle is provided with` waterinlets and outlets and also with automatic means for regulating the amount of heating iiuid which is to pass through-the pipes or to shut off said iiuid at a given time; and the objects of my invention are, rst, to provide an intermittent or continuouslyoperating waterheater; second, to provide a heater which shall raise the water to any desired temperature during its passage through the heater from the water-main, and third, to provide a device of simple and economical construction. I attain these objects by the mechanism illustrated in the accompanying drawings, in whichV Y .1 y
Figure l shows fan elevation ofthe heater and its connections. Fig. 2 shows a similar view, partly in section, to illustrate the interior arrangement.
Similar letters referto similar parts throughout both views.
The water-receptacle proper A is mounted on any suitable base, as A3, and is preferably cylindrical in form, having end plates A and A2 to close either end. The end plate A' may, if desired, be formed integral with the support AS or as indicated in Fig. 2. Within this receptacle A are mountedthe fluid-heating pipes B. These pipes may be arranged in any manner to provide a sufficient heatingsurface to accomplish the objects of the device. The form preferred, however, is that shown in Fig. 2, in which headers b' and h2 are mounted near each end of the receptacle and have connected therewith the coils B. One of the headers, as b', is connected with the steam-supply pipe B', having a valve D', operated in a manner hereinafter described. The opposite header h2 is connected with a steamenhaust or drip pipe B2, which in turn may be connected with a steam-trap E of any wellknown construction. Theinlct for the water if desired.
supply is preferably arranged as shown, and consists of a water-pipe C, adapted tobe connected with any source of water-supply and having a portion c extending substantially the full length of the receptacle to'a point near the bottom. The opening forthe wateroutlet is arranged adjacent the opening for the water-inlet and is fitted with a pipe C'. The base of the receptacle is preferably p`rovided with a drain-pipe d, having a valve a'.
Connected with the steam-valve D' of the pipe B' is a thermostat DV of any desired form. This thermostat has a part d2 projecting into the water-receptacle near the outlet, whereby the temperature of the water at a point adjacent to the outlet C will determine the volume and pressure of the steamlsupply passing through the valve D'. The steam-pipe B' and the water-outlet C' maybe providedjwith indicators x and y, respectively, if desired. Furthermore, the water-pipe'C may be provided with a relief-valve z, if desired. The pipe d3, which joins the thermostatD with the valve D', may also be provided with a drip-pipe d',
The operation of the device is as follows: Cold waterfrom the givenlsource is turned into theheater through the pipe C at `a point near the bottom. lVhile the receptacle is lling with water steam is admitted to the coils B through the pipe B. At this time the' apparatus' is more or less cold, and the thermostat D therefore permits of a maximum volume of steam through the valve D'. Vhen,
however, the water reaches the part d2 of the thermostat D, the temperature of the water as it rises from the effect of the heat of the steam-coil B will greatly influence the ther-`-` mostat D to close the valve D', and thereby lessen the amount of steam admitted to the coils until the desired temperature is` maintained. The thermostat maybe adjust,- ed so as to permit the water to reach any `desired temperature before the steamis,A cut off, and therefore the user of fthelwater may determine the temperature at will in any of the well-known ways of regulating such thermostats.
The parts of the device are so proportioned that it is possible to have the water-inlet and water-outlet open to their fullest extent, thus allowing for a continuous steady stream of hot water. This is accomplished by reason of the diameter of the steam and waterpipes and the capacity of the receptacle A.
In the construction illustrated in the drawings the cold-water inlets and the hot-water outlet are large enough for a light pressure. For heavy pressure they can be made smaller. The steam connections are of sufficient size for low-pressure steam. For high pressure they can be reduced in size.
For an average water-supply the following proportions have been found most practicable: diameter of receptacle A, twenty-two inches; height over all, seventy-two inches; capacity in gallons per hour, two thousand ive hundred; cold-water inlet, two inches diameter; hot-Water outlet, two inches diameter 5 steam-inlet, two inches diameter; dripoutlet, one inch.
Having now fully described my invention, what I claim, and desire to secure by Letters Patent, isi l. A water-heater comprising a suitable tank, a plurality of heating-coils extending from top to bottom thereof, an inlet-pipe entering at the top and extending to the bottom of said tank, an outlet-port at the top of said tank and a thermostat adjacent said outlet, a steam-inlet controlled by said thermostat.
2. A water-heater comprising a suitable tank, a plurality of heating-coils extending from top to bottom thereof, a water-inlet'pipe entering near the top and extending substantially to the bottom thereof closely adjacent to said heating-coils, an outlet-port near the top of said tank and a thermostat near said outlet and controlling the supply of steam to the coils.
3. A water-heater comprising a suitable tank, heating-coils extending therethrough, a water-inlet pipe entering at the top, extending close to said heating-coils, and discharg ing at the bottom of said tank, an outlet-port at the top of said tank and a thermostat extending between the heating-coils and adjacent said outlet-port and controlling the supply of steam to said coils.
VIn witness whereof I have afiixed my name, in theipresence of two subscribing witnesses, this the lst day of July, A. D. 1902.
