HEATER FOR FEED-WATER.

SPECIFICATION formingpart of Letters Patent No. 246,370, dated August 30, 1881,

Application filed June 13, 1881. (No model.) I

To all whom it may concern:

Be it known that I, HENRY OoKEn, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Heaters for Feedater, of which the following is a specification.

My invention relates to improvements in feed-water heatersin which I employ an upright cylinder having cold-water and condensed-water compartments below, an exhaust-steam chamber above the cold-water chamber, and

the cold-water chamber below connected with an open topped waterchamber above the steam-chamber; and the objects of my invention are, first, to provide a feed-water heater in which the cold water from a tank above is fed into the cold-water chamber and becomes heated as it passes through a series of openended flues heated by exhaust-steam to the discharge-chamber above; second, to afford facilities for carrying the condensed water in the steamchamber into a chamber below the cold-water chamber; third, to provide means by which the condensed water in the chamber below the cold-water chamber is forced therefrom into the open-topped chamber above the steam-chamber; fourth, to provide a means for conveying the water which is condensed in the steam-chamber below the cold-water chamber; fifth, to provide a means for showing when the condensed water has accumulated sufficient to be forced into the open end of the heater; sixth, to provide a means for keeping a head of water on the feed-pump. These objects I accomplish by the devices illustrated in a single figure in the accompanying drawing, in which A and B represent an ordinary furnace and boiler, the boiler being provided with the usual steam-dome, O. E represents an ordinary coldwater pump. K is a cold-water tank, located a little distance above the boiler. Z represents the hot-water feed-pump, and 0 represents a sectional view of the shell of the heater. The shell 0 is cylindrical, and is provided with a bottom head, a, and above the chamber P is another head or partition, n. Above the partition n is the lower flue-sheet, t, with lines T extending from said sheet to the top fluesheet, t, thus forming a steam-chamber, S, in

the shell 0 around the flues T. The upper end of the shell 0 is left open, forming the chamber R. The chamber P below is to receive the water from the condensed steam in the steamchamber, and the chamber Q, is the cold-water chamber.

The exhaust from a steam-engine and leaksteam from cylinder-cocks is conducted into the steam-chamber S by the pipe V, and the pipe U forms the discharge of steam from said steam-chamber. The cold-water pipe J leads from the bottom of the cold-water tank K into the chamber Q, and is provided with a valve, 0, for regulating the flow. The water as it fills the chamber Q rises in the flues T to the chamber R, above the upper flue-sheet, t. The pipe Y leads from the bottom of the chamber R to the hot-water feed-pump Z, and is provided with a valve, i, for regulating its flow. The pipe Y is further provided with a standpipe, W, near the pump, which keeps a head of water to the suction of the pump Z. The pump Z is operated by steam irom the boiler B through the pipe H H.

F is the discharge-pipe from the cold-water pump to the tank K, and G is the steam-pipe for operating said pump.

The pipe L connects the lower end of the steam-chamber S with the upper end of the chamber R, and is provided with a check-valve, d, arranged to allow the condensed water in the steam-chamber to be conducted to the chamber It.

Outside of the pipe L or at any convenient place on the shell 0 between the chamber P and steam-chamber S is a glass gage, Mf, arranged to show when the chamber P is full of condensed water. The steam pipe I, with valve 1), connects with the upper end of the chamber P, and the discharge-pipe r 1" leads from the bottom of the chamber 1 to the open chamber 1% of the heater. WVhen the chamber P becomes full of condensed water steam is admitted through the pipe I, and the water in the chamber 1? is forced through the pipe 1 4 into the chamber R, Where it is used as feedwater.

The pipe at leads from the feed-pump to the stand-pipe D of the boilerin the usual manner.

In operation cold water is pumped into the tank K and passed through the pipe J to the chamber Q,flues T, and chamber R. The steam surrounding the fines T heats the water passing through them, and the condensed water collected in the chamber P is utilized, as before described.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. The shell 0, with bottom head, a, partition a, lower and upper flue-sheets, t t, and fiues T, forming the chamber P, for condensed water, the chamber Q, forcold water, the steamchamber S, and open chamber 1t, substantially as shown and described.

2. In combination with the heater consisting of the chambers P, Q, S, and R, the inlet-
