BOlLER-FEEDER.

SPECIFICATION forming part of Letters Patent No. 453,526, dated June 2, 1891.

Application filed December 10,1890. Serial No. 374,151. (No model.) 1

To @ZZ whom it may concern:

Be it known that I, JOHN E. WINDER, of St. Louis, State of Missouri, have invented a new and Improved Boiler-Feeder, of which the following is a full, clear, and exact description.

The invention relates to boiler-feeders such as shown and described in the application for Letters Patent of the United States, Serial No. 303,802, filed by me September 3, 1890,

and allowed November 24, 1890.

The object of the present invention is to provide a new and improved boiler-feeder which is simple and durable in construction, very eiective, and entirely automatic in operation, precipitating any impurities in the Water, and heating the latter previous to its entrance to the boiler.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed ont in the claims.

Reference is to behad to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with parts in section. Fig. 2 is an enlarged sectional plan view of part of the iinprovement on the line 2 2 of Fig. 1 and Fig. 3 is an enlarged transverse section of the saine on the line 3 3 of Fig. 2.

The improved boiler-feeder is provided with a suitable receptacle or tank A, located in the immediate neighborhood of the boiler' and above the water-level in the boiler, as shown in Fig. 1. Into the receptacle or tank A discharges the supply-pipe B, connected with a suitable source of water-supply and having its inner end provided with perforations, as shown. From one end of the receptacle or tank A extends a pipe C, provided with a valve D and opening into the boilerE at any desired point, preferably a suitable distance below the normal water-level.

Into the water-supply pipe B, inside of the receptacle or tank A, opens a nozzle F, secured to the lower end of a pipe G, opening at its upper end into an opening H', formed in a head H, secured to one end of the receptacle A, as is clearly illustrated in the drawings. Into this opening II also leads one endof a steam-pipe I, passing through the receptacle A and into the boiler E at its water-level, so that the live steam from the boiler can pass through the said pipe I into the opening II', and from the latter through the pipe G and nozzle F into the supply-pipe to force thc water through the pipe into the receptacle or tank A, at the saine time iningling the steam with the water, so as to precipitate the impurities.

The opening H is adapted to be connected at its top with or disconnected from the interior of the receptacle or tank A by means of a valve J, seated on the inside of the opening Il. The valve J is hung on a pin K, sup ported on the lever L, fulcriimed at L on the head II. The lever L is pivotally connected by 'a link N with a lever O, fulcrumed at O to one end of the receptacle or tank A, and carrying at its other end a Iioat O2, which rises and falls with the water-level in the tank A. The lever O passes through a slot a in the link N, which allows the lever O t-o rise or fall to almost an extreme upper or lower position before acting on said rod. The slightest unseating of one of the valves P J causes the steanrpressure to promptlyseat the opposite one, and therefore only a slight movement of the link N is required. The movement of the lever O between its two extremes has no effect on the said link and valves. In the head H is formed a second opening H2, adapted to be thrown in communication with or disconnected from the interior of the tank or receptacle A by means of a valve P, adapted to be seated on the outside of the head, said valve being also hung on the pin K. Thus when the lever L is moved one valve is seated while the other is unseated, and vice versa. Vhen the float O2 is in the lowerinost position, as shown in Fig. 1, then the valve P is unseated and the opening H2 is connected with the interior of the receptacle or tank A, while the other valve J is seated and the opening I-I is disconnected from the interior of the receptacle or tank A.

The opening H2 is connected with an exhaust-pipe Q, extending to the outside of the receptacle or tank A. In the bottom of the latter are arranged two branch pipes R, opening into a pipe S, into which the impurities are precipitated by the steam, and settle, to

IOO

be conveniently removed therefrom. In the feed-pipe B is arranged a column T, adapted to be filled with a suitable compound, which gradually feeds through a lazy-cock T past the Valve U into the feed-water, to pass into the receptacle or tank A to lubricate the several part-s therein, and which also causes the dissolution of scale or incrustation and prevents the formation of the same in the boiler.

It will be seen that the purge compound will be thoroughly mixed with the water by the action of the steam from nozzle F.

The operation is as follows: The water entering the supply-pipe B passes into the receptacle or tank A and gradually lls the same, so that the float O2 rises and the lever O swings into an uppermost position. This upward movement of the lever O causes the link N to actuate the lever L, so that the valve vP is iinally closed and the valve J is opened. Live steam from the boiler can now pass through the pipe I and opening H into the top of the receptacle A to press on the water therein, so that the pressure in the receptacle is equal to the boiler-pressure, and the Water in the receptacle can now freely flow through the pipe Cinto the boiler. As soon as the tank A has emptied the float O2 reaches its lowermost position, and by its connection with the lever L again closes the valve G and opens the valve P, so that the steam in the receptacle A can escape through the pipe Q, and the boiler-pressure causes the closing of the valve D, whereby the receptacle A is disconnected from the boiler. The water flowing in from supply-pipe B again gradually raises the fioat O2, and the above-described operation is repeated until the water in the boiler shall rise high enough to coverthe pipe I, which will prevent the steam from entering the tank A. Thus the water will be retained in tank A until the water in the boiler shall fall below the required level again, thereby automatically maintaining the water in the boiler at a predetermined level.

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

l. In a boiler-feeder, the combination, with a tank connected with and arranged above the water-level of the boiler, of a supplypipe entering and discharging into the said tank, a nozzle within the tank openin g into the said supply-pipe, and a steam-pipe entering the tank and connected with the said nozzle and substantially as shown and described.

2. The combination, with the tank having a valved inlet-pipe and a Valved outlet-pipe, of a horizontal head H above the inlet-pipe provided with two chambers H H2, having openings in their top walls communicating with the interior Aof the tank, the exhaustpipe leading from chamber H2, a vertical pipe G, connecting the chamber H with the inlet and terminating in a nozzle within said inletpipe, a steam-pipe I, discharging into the chamber H', a vertically-rocking lever L on top of the head, valves .I P, closing upward and downward, respectively, in the respective chambers H H2 and suspended from one end of said lever, a link depending from the opposite end of said lever, and a lever O, engaging said link and provided with a float, substantially as set forth.

3. The combination, with the tank having within it a head provided with valved chambers for discharging steam into and exhausting it from the interior of the tank, and a float for simultaneously operating said valves, of a water-supply pipe entering the tank below said head and provided with a steamnozzle, a pipe G, leading from the steam-sup! ply chamber down to said nozzle, and a column T outside of the tank and connected at its lower end to the water-supply pipe outside of or beyond said steam-nozzle to supply a purge to the water before it is acted on by the steam, substantially as set fort-h.

4. In a boiler-feeder, the combination, with a tank, a supply-pipe discharging into the said tank, and an outlet-pipe containing a valve and connected with the boiler, of a head held in the said tank and provided with a steam-inlet opening and an exhaust-opening, valves adapted to alternately open and close the said openings, a steam-pipe connected with the said inlet-opening, a lever provided with a iioat and controlling the said valves, and a pipe leading from the said head inletopening and provided with a nozzle opening into the supply-pipe, substantially as shown and described.
