dated August 12, 1902.

Application filed February 23, 1901 Serial No- 48,419. (No model.)

To atZZ whom it may concern:

Be it known that I, HARRY J REYNOLDS, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented acertain new and useful Improvement in Feed-Water Heaters and Purifiers, of which the following is a full, clear, and exact description, reference being had to the'accompanying drawings. I

The invention has for its, object the heating of the feed-Water for a boiler and the removal of the greater part of the impurities contained therein before said heated water is discharged into the boiler. I

The invention consists of the combination of an open top receiver supported in the steam-space in the boiler and having a valvecontrolled discharge-pipe connected with its the boiler, a heating-pipe in the boiler located, preferably, below the normal water-line and having. its outlet above and in position to discharge into said receiver and having in its inlet end outside of the boiler a blow-0d cock.

In the drawings, sectional elevation of the boiler equipped with the present invention. Fig. 2 is a transverse sectional elevation on line 2 2 of Fig.

1, andFig. 3 is a plan view of the heating pipe.

Referring by dicates a boiler,

letters to parts shown, A inwhich may be of any suitable B represents the feed-water receiver, which in the best construction is in the form of an open-mouthed funne 'It is located in the steam-space in the boiler above the water-line a; (1:, with its open top as near the top of, the boiler as convenient. Adischargepipe I), connected with its lower tapered end, is extended out through the boilerwall and is provided outside the boiler with a blow-ofi? cock I). a

The heating-pipe D, which consists of a plurality of coils or convolutions, is located in the boiler and preferably below the Water line, wherefore boiler-water. The discharge end (Z of this heater-pipe is extended up and over the. receiver B, wherefore the water which is forced through the heater-pipe is delivered into this receiver. The inlet end of this heater-pipe outside the boiler contains a check-valve (Z contains impurities held in suspension Figure 1 is a longitudinal it is-submerged in the hot and between this check-valve and the boiler wall a blow-off coo pipe D. I 4 p In the operation of the described device the water forced through the pipe D is heated, so that when delivered in the receiver B it'is at nearly the temperature of the boiler-water. The feed-water used in boilers ordinarily and a very considerable quantity of impurities which do not separate therefrom until the water is heated. These impurities last referred to, together with the impurities which thewater when cold holds in suspension, or rather such part :of such impurities as are heavy enough, will settle to the bottom of the receiver B, and the purified water will flow over the edges of said receiver and mingle with the boiler-water. At suitable intervals the impurities which have settled to the bottom of the receiver B may be blown out by opening the blow-0E cock- 6. In like man- .ner such impurities as may havesettled in the heater-pipe D may be blown out by opening the blow-0E cock (1.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

d is connected with said steam-boilers, the combination of a feed-pipe leading into the boiler, a-horizontal heatingboiler in a plane parallel with but just below the normal water-line of the boiler and a pipe leading up from the inner end of the coil and having its discharge end curved over and downwardly, with an open-topped funnel shaped receiving vessel locatedin the boiler below said dischargeoutlet of the heatingcoil but above the normal water-line of'the boiler and a discharge-pipe connected with the lower end of said receiving vessel and extending out through the shell 'of the boiler, together with suitable valves in the-feed and discharge pipes, outside of the boiler, to control them, substantially as specified.
