BOILER-FEED.

SPECIFICATION formngipart of v Letters Y'Patent No. 522,393, dated July 3, 1.894.

Application filed September 1l 1893. Sverial No. 484,564. (No model.)

citizen of the UnitedStates, residing at Potts# town, in the county of Montgomery, State of Pennsylvania, have invented a new and use` ful Improvement in Boiler-Feeds, which irnprovement is fully set forth in the following specification and accompanying drawings. 1

My invention consists of novelv means forA heatlng the feed Water of a steam boiler or generator, and causing a circulation of the same through the boiler and heating device, as will be hereinafter set forth.

Figure I represents a side elevation of a boller feed embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents a longitudinal section of one ,of the valves thereof; Fig. 4 represents a section on line Fig. 3.

Similar letters of reference indicate correspondmgparts in the several figures.

Referring to the drawings:,A designates a boller feed of any desired construction and B designates the water supply or feed pipe thereof. Connected with said pipe Bis a pipe C, which extends under the'jboiler, and hasv connected with it thereturn pipe or bend D, which is Within the vfurnace E, and'is connected with one end of the drum F, the latter formlng the bridge Wall of the furnace. Connected with the other end of the drum is a plpe G, which is also `locatedwithin the furnace, similar to the return pipe D, it being lllustrated below the broken-away part in Flg. 2, and connected with the pipe H, which extends under the boiler and is connected with the branch J,which leads into the boiler as at K.

At the junction of thepipes B and C is an automatically-operating valve L, the same consisting of a shell M having within the same the head or valve N, and seats P and Q at opposite ends, so that said valve L may be closed on the seat P, and opened on the seat Q, or vice-versa, it being noticed that the pipes B and C are coupled to the shell M, and communicate with the interior thereof. Leading from the shell of the valve L, and openb ing into the boiler is a branch pipe B.

' The Walls of the seats P and Q are formed with grooves R, which constitute channelsY which permit the passage of Wateror steam,

as the case may be, around said valve N.

The pipe B is provided with a valve S for regulating the iow of water to the 'feed pipeB- r "l The operation is as follows: The valve S is opened, and waterl flows into the pipelB,'and pressing against the valve N closes the same against the seat P, whereby ysaid valve is open onthe' seat Q.- The water now'l'lows through the valve and enters the pipe C, it being noticed that steam is cutoff from the pipe C,

owing to the closed valve N, as shown in Fig.

3. The water then ows through the pipe C land the pipe D, and crosses through the drum F into the pipe G, and flows through the pipes H, J, and so enters the boiler in highly heated condition, as the pipes D and G, certain portions of the pipes C and H, and the drum F are subjected to the direct products of combnstion in the furnace E, and the remainder of the pipes C and H are subjected to the products of combustion under the boiler behind said drum, the latterV acting asy the bridge Wall of the furnace, the effect of which is evident. When the boiler is supplied, the valve S is elosefd,`and the iiow of Water ceases, and the valve L having the water pressure removed therefrom is now subjected to pressure from the boiler through the pipe B'. This causesthe valve N to open on the seat P, and close on the seat Q, whereby the pipe C is in communication with the boiler through the pipe B', and the Water may now circulate through the boiler and theseveral heating pipes, thus effectively producing steam in large volumes.

Having thus described my inventiomwhat I claim as new,l and desire to secure by Letters Patent, is y 1. A boiler feed consisting of a feed pipe, a heating pipe leading from said feed pipe to a boiler, a steam pipe and a shell connecting said feed, heating and steam pipes, and having 'an automatic valve adapted to either open or close the communication between the feed and heating pipes, and closeor open the communication between the steam and heating pipes, said parts being combined substantially as described.

2. A boiler feed having a feed pipe, a heating pipe in communication therewith and leading into a boiler, a steam pipe communieating with said heating pipe and an automatic valve controlling the communications between said feed, heating and steam pipes, said parts being combined substantially as described.

3. In a boiler feed, the shell M having seats at its Opposite ends with channels in their walls, the pipes B and B connected with the ends of said shell, the pipe C connected with said shell intermediate Of said pipes B and B', and the valve head N in said shell adapted to automatically open or close the communication betweon pipes B and C, or B and C, Substantially as described.

4. A boiler feed and heater therefor con sisting of the feed pipe B, the heating pipes C, D, the communicating heating pipes G and II, the heating drum and bridge wall F connecting said pipes D and G, and an automati cally-acting valve intermediate of the pipes B and C, adapted to open said feed pipe and then close the same, causing a circulation of water through the boiler and heating pipes, said parts being combined substantially as described.

5. A boiler feed and heater therefor, consisting of a feed pipe with the valve S therein, a heating pipe in communication with said feed pipe, a drum forming the bridge wall of a furnace, a pipe leading from said drum into the boiler, a shell with valve seats in each end, and a valve head in said shell, aseetion of said feed pipe being between said shell and boiler, and said valve-head controlling the communication between section of feed pipe and the heating pipe, said parts being combined substantially as described.

6. A boiler feed having a feed pipe, aheating pipe, and a shell with an automatic valve therein, a section of said feed pipe being intermediate of said shell and boiler, and said valve controlling the communication between said section and the heating pipe, and also the communication between the main body of the feed pipe and the heating pipe, said parts being combined substantially as described.
