UNITED STATESy PATENT OFFICE.

HENRY e. KEAsBEY, or AMBLER, PENNSYLVANIA.

FEED-WATER H EATER.

SPECIFICATION forming part of Letters Patent No. 525,552, dated September 4,1894.

Application filed January 18, 1894i Serial No. 497.244. (No model.)

To all whom it may concern:

Beit known that I, HENRY G. KEAsBEY, a citizen of the United States, residing at Ambler, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Feed-Water Heaters, Economizers, and Purifiers, which improve ment is fully set forth in the followingspeciication and accompanying drawing.

My invention consists of a feed water heater, &c., formed of a chambered shell with flues and pipes therein, inclosed end chambers for said shell, one of which is adapted to serve as an inlet for live or exhaust steam, and the other as an outlet chamber for the same, said iiues terminating in said end chambers and said pipes serving to impart a zig-Zagor alternating top and bottom motion to the Water throughout the heater while it is being subjected to the action of the steam, the heating being gradual and being effected by either live or exhaust steam, all as will be hereinafter set forth.

The figure represents a partial longitudinal section and partial side elevation of a feed water heater, dac., embodying my invention.

Referring to the drawing: A designatesa shell within which are partitions B, forming chambers C, C', C2, C3, and pipes D, D', D2, which extends from the top of one partition to the bottom of the chamber which said pipe occupies. V

Connected with the chamber C is a water supply pipe E and with the chamber C3 isa discharge pipe F, it being evident that after water enters the chamber C, it rises in the same, and is directed by the pipe D to the bottom of the chamber C', where it is discharged. The water then rises in said chamber and is discharged by the pipe D into the chamber C2 at the bottom thereof, and so on with the pipe D2 and chamber C3, the water thus being directed in zig-zag course throughout the chambers of the boiler, and being subjected to the action of the fines B with which the water comes in contact in said course, said iiues being heated by steam which is directed by a pipe G from a source of supply into a chamber H, which is formed on the end of the shell A, adjacent to the chamber C3 thereof, the same having the flues B in communication with the same, it being evident that the steam enters the chamber H through the pipe G, and is directed into the flues B, thus heating the water in the chambers C3, C2, C', C, the heating being gradual as the temperature of the chambers increase, the chamber C3 being the highest temperature, since the exhaust steam enters the flues B in said chamber C3, while it discharges where the fines are in the receiving chamber C, the steam in its low temperature then entering the chamber J, which is connected with the shell A opposite to the chamber H, and provided with a discharge pipe K. The shell is also provided with blow-off pipes L, and the chambers H and .I with blow-od pipes M for removal of sediment or deposit, &c.

Man or hand-holes are formed in the shell and partitions also if desired, and covering plates provided for the same, whereby access may be had to the interior of the shell for .purposes of cleansing, repairs, &c.

.connected with the due of a boiler and to receive the said hot gases therefrom, the other parts being also arranged with this especial object in View. In the other case the feed water heating device. andthe boiler proper are combined into a single structure, one end chamber of the same terminating adjacent to the fire box, above which is the steam dome, and the connections from the top of one chamber to the bottom of an adjacent chamber being made preferably partially exteriorly of the same. To none of the above constructions do I make claim in the present application.

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

1. A shell having partitions therein, forming separate water chambers, lines through said chambers, pipes connected with said partitions, forming communication between the chambers in zig-zag order through the heater, said ilues terminating. at their extremities in ICO closed chambers, one of which is adapted to serve as an inlet for live or exhaust steam, and the other as an outlet chamber for the same, said parts being combined substantially as described. Y

2. A feed water heater and purifier, consisting of a shell having inclosed chambers in bot-h its ends, one of which is adapted to Vserve as an inlet for live exhaust steam, and

the other as an outlet chamber for the same, lues connecting said chambers, partitions forming water chambers between said steam Y chambers, a water inlet pipe leading into the Witnesses:
