FEED-WATER HEATER AND PURIFIER.
SPECIFICATION forming part of Letters Patent No. 556,336, dated March 17, 1896.
Application iiled April 22, 1895. Serial No. 546,672. (No model.)
T0 all whom t may concern.-
Be it known that I, J AMES E. ORAWLEY, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Feed-Tater Heaters and Purifiers; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its object to improve and simplify certain portions of the feed-water heater shown in my prior patent, No. 537,019, granted on the 9th day of April, 1895; and to that end said invention consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter and subsequently claimed.
In the drawings, Figure l. represents a vertical central section through a feed-water heater and purifier embodying my present invention, certain adjacent parts being represented in elevation. Fig. 2 is a like sectional view of portions of said device, drawn to an enlarged scale, and with the movable parts shown in reversed positions from the positions shown in Fig. l Fig. 3 is a detail sectional view taken on the line 8 3 of Fig. l and likewise drawn to an enlarged scale.
Referring to the drawings', A represents a condensing-chamber, B the outer shell supported on legs E E, and C the inner tank, having a wash-out pipe D, of a vertical heater, there being a shell or casing G communicating with the exhaust inlet-pipe H at the farther end of the condensing-chamber, and the said heater being provided with a vertical filter J, comprising a perforated metal tube K, eX- ternal wrapping of burlaps L, inner perforated metal pipe M, and coke or other filtering material m, interposed between the tube K and pipe M, all substantially as in my said prior patent hereinbefore referred to, wherein the said parts are designated by the same reference-letters.
The described inner pipe M of the filter is connected as before to a tubular receiver N for the filtered water, having a top N with a communicating pipe P, but the float-ball O within the receiver in my present device is differentlyconnected and operates in a different manner from that set forth in my said prior patent. In the present case O represents a rod or post rising from and supported by the base of the said receiver N, and in the upper end of the rod or post there is journaled one end of a shaft R2, which passes out through the outlet-pipe R for the hot filtered feed-water and through a connected fourway coupling r, pipe 1" and stuffing-box r2, and terminates in a butterfly-valve R3 in a valve-chamber Q3 in the pipe Q, leading from the supply of cold water, which pipe at Q enters the condensing-chamber A and terminates in a trough Q2.
The described float-ball O is secured to a stem O2, which passes through a perforation in a block O3, (being adjustably secured therein by set-screw 04,) said block having another perforation therethrough at right angles to the one just described, whereby it is mounted on the described shaft R2, to which it is secured by set-screw O5.
In small or medium sized heaters the tubular receiver N is preferably formed with an enlargement N2 to make room for the said float-ball in its descent, as hereinafter described. The shaft R2 is preferably provided with a weight R4, as shown.
R/ is a pipe leading from the lower branch of the four-way coupling r to t-he pump (not shown) that supplies the boilers with the purified feed-water.
S is a live-steam pipe connecting with the upper branch of said coupling r and leading from the boiler. (Not shown.) A coupling r3 is connected to the outlet of pipe r and to the inlet of a water-gage U, the upper end of which, as shown at u, intercepts a vertical equalizing-pipe T, which passes up from the described coupling r3 and connects by a crosspipe T with the upper end of the described pipe P, which communicates with the receiver N. P is a transverse pipe entering the said pipe P and provided with an equaliZing-valve p, controlled by a hand-rod p2, passing up and out through the top of the heater-shell.
The pipes Q S are braced apart and strengthened by a rod T2, which is merely a blind pipe without any communication between the other pipes named.
The operation of my device will be readily IOO understood from the foregoing description of its construction, taken in connection with the accompanying drawings. The cold water enters the condensing-chamber A through the pipe Q Q' and trough Q2, and is heated by exhaust-steam from the inlet H, j ust as in my said prior patent, the steam and Water entering the heater as before, the steam filling the steam-space c between the tank C and its outer shell B, forming a steam-jacket for the said tank and escaping out through the open outlet c and keeping the water in the tank which has flowed in through the opening above the partition b always at the temperature of the exhaust. This heated water passes through the burlaps, perforated tube, and coke iilling of the filter J and enters the perforated pipe M, passing up into the tubular receiver N, from whence it passes to the pump through the outlet-pipe R, coupling r, and communicating pipe R. W'hile the cold water is being supplied to the chamberA the floatball O is down and the butterfly-valve R3 in the valve-casing Q3 in pipe Q is open, as shown in Fig. 2; but when the water in the tank reaches a predetermined level it is desirable to cut off the supply of cold water, and hence the float O (whose stem O2 has been adjusted to the corresponding length desired) will rise within the receiver N to said level, thereby partially revolving the shaft R2 and closing the valve R3 in the casing Q3, the parts being then in the positions shown in Fig. l. The gage U always shows the height of the water within the receiver N. Then the supply of heated water falls below the required level, the ball O falls with it and by means of its described connections instantly opens the valve R3, the movement of the shaft R2 being facilitated by the described weight R4. The described equalizing devices p2, p', P', P, and T serve to reduce the water in tank C, receiver N and gage U to a common level whenever said level is disturbed by the exhaust-pressure within the said tank, in the same manner precisely as set forth in my said prior patent.
I have found in practice that my herein-described means of regulating the supply of cold water to the heater is an improvement over the means described in my said prior patent, being simpler and more direct, and obviating the possibility of any cramping or binding of the valve-rod and connections.
IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The combination in a feed-water heater of a suitable tank and cold-water receiver, a filter within said tank, a tubular receiver communicating with said filter, a cold-watersupply pipe having an outlet within said chamber, and a valve-casing opposite said receiver, an outlet-pipe leading from said receiver in line with said valve-casing, a shaft supported within said receiver and passing through said outlet-pipe and into said valvecasing, a butteriiy-valve on the end of said shaft within said casing, and a float-ball provided with a stem connected to said shaft within said receiver, substantially as set forth.
2. The combination with a feed-water heater of a suitable tank and eold-water-supply pipe, a tubular receiver for filtered water within said tank, and an outlet-pipe leading therefrom and passing through said tank, avalvecasing within said cold-water-supply pipe in line with said outlet-pipe, a shaft supported within said receiver and passing through said outlet-pipe and into said valve-casing, a butterfly-valve on the end of said shaft within said casing, a float-ball provided with a stem adjustably connected to said shaft within said receiver, and a weight secured to said shaft exterior to said tank, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of lVisconsin, in the presence of two witnesses.
