FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 540,370, dated June 4, 1 895.

Application filed March 29, 1895.

T0 at whom it may concern.-

Be it known that I, BIRT VICTOR, a citizen of the United States, residing at Harper, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in FeedWVater Heaters; and I do here by declare that the following is a full, clear,

and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its object to provide a feed water heater for steam boilers that will be simple in construction, effective in operation, and result in an economy of fuel when in use, and in many respects possessing advantages not obtained in the feed water heaters in ordinary use.

The invention consists in a feed water heater constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a vertical section taken on line 00 w of Fig. 2; Fig. 2, a top plan View with the funnel-shaped top removed; Fig. 3, an under side plan view with the bottom removed.

- In the accompanying drawings A represents the body or casing of the feed water heater provided with a suitable bottom B and at a short distance from the top of said body or casing is a diaphragm G, which diaphragm may be secured in place by any well known means or placed. in the casing loosely and rest on supports projecting from the interior of the body or casing or be supported by the water tubes hereinafter described.

Suitable water-tubes D are located in the body or casing A and project up through the diaphragm 0, any number of said tubes being employed as found most desirable, but in the present instance there are four of these tubes shown. These tubes may be secured to the diaphragm by having upon the ends which project above the diaphragm suitable screw threads with which engage nuts (1, or any other well known means may be employed asfound best adapted to the purpose.

The water tubes D extend down into and partly across the lower end of the body or casing A and near the bottom thereof and diverge to a common center, said tubes being Sen'al No. 543,697., (No model.)

provided with elbows b, which are connected in the present instance to a four-way coupling E by means of the tubes F, which tubes have one or more holes or openings 0.

An inlet pipe G connects with the interior of the body or casing A at a point below the diaphragm O for the exhaust steam from the engine or from any other source, and at the opposite side of the body or casing on about the same horizontal plane, is an outlet pipe H which communicates with the interior of the body or casing and is for the exhaust steam that is not condensed.

Communicating with the interior of the body or casing A near the bottom thereof is the pipe I for drawing off the hot water to feed to the boiler.

The top K of the body or casing A is funnel shaped with a central opening d, said funnel having circumferential flange eof sufficient height to rest upon the flange f of the diaphragm O and elevate'the central opening above and from contact therewith.

The operation is as follows: WVater from any source sufficient to keep the body. or casing A properly filled, is permitted to run into the funnel shaped top K and through the central opening d thereof and thence onto the diaphragm G, where it rises to the ends of the tubes D and flows gradually into the same and passes down said tubes and out through the holes or openings 0 into the body or casing, after which it is drawn off through the pipe I. The level of the Water in the body or casingA is retained slightly above the outlet phragm O is formed an exhaust steam chamber which is supplied with steam from the pipe G, the escape pipe H preventing any pressure in the chamber. It will beseen that the water is first heated as it slowly runs over the diaphragm O and again as it passes through the water tubes D where it is deposited in the bottom of the body or casing for use. 7

Any well known and desirable means may be employed for connecting thevarious pipes with the body or casing, although in the present instance there is shown screw nipples g with which the screw threaded ends of the that may be employed.

pipe I so that between the water and diapipes engage, as being one of many means A heater constructed as herein described is very efficient especially when it is provided with any well known boiler covering for retaining the temperature in the heated water.

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

1. In a feed water heater, the combination of the body or casing provided with a diaphragm near the top thereof, with water-tubes extending down and converging to a common center, and a coupling in common for all the water-tubes, said water tubes being provided with holes on their converging side's, which communicate with the interior of the casing, whereby the water of condensation and the heated feed water commingle, substantially as and for the purpose specified.

2. In a feed water heater, the combination of the body or casing provided with a diaphragm near the top thereof, with Water tubes extending downwardly therefrom, and a funnel shaped top located over the diaphragm and having a central opening, substantially as and for the purpose described.

3. In a'feed Water heater, the combination of the casing provided with adiaphragm near the top thereof, an exhaust steam inlet and outlet, a water outlet, with the water tubes extending down and converging to a common center and provided with openings on their lower converging sides, and a funnel shaped top located over the diaphragm and having a central opening, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

BIRT VICTOR. Witnesses:

COLLIN L. ROBERTSON, FRANK WERTZ.
