I Specification forming part of Letters Patent No. 152,360, dated vJ une 23. 1874; reissue No. 6,802, dated December 14, 1875 application lled July 29, 1875. a

.To all who-m it may concern:

Be it known that I, RICHARD GAas'rANG, of'St. Louis, St. Louis county, State of Missouri, have invented a certain new and useful Improvement in Feed-Water Heaters, of which the following is a specification:

, My improvement consists in a feed-water heater having three chambers in a vertical series. .The upper and lower of these chambers, communicate together by pipes 'passing through the lniddle chamber. A filter occupies the'lower part of the upper chamber The exhaust steam from t-he engine enters the central chamber at the bottom upon one side,

pipes, traversing the central chamber, and

through theilter into the part of the upper chamber above the filter, and the clear water ows to the boiler through a pipe communieating with said chamber just above the level of the filter. The scum accumulates at the top of the upper chamber, and is from time to time blown out through a blow-o' pipe.

In the drawings, Figure 1 is a vertical axial section of the heater. Fig. 2 is a top view with the upper head removed.

A and B are the hemispherical heads,l secured to the cylindrical castings G D by flanges and bolts E F, as shown, or in any other suitable manner. Theinner ends of the parts C D consist ,of tube-sheets c d, through which pass the pipes G, that form communication between the lower chamber H and the upper chamber J. The pipes -G pass vertically through the middle chamber I, and into this chamber the steam is exhausted.

The tube-sheets c d divide the case into the three chambers H I J. The sheet-metal cyl inder K forms the side wall of the central chamber I, and it is connected to the parts C D by rivets. L is the filter divided horizontally into three compartments, which slide the one into the other. `The bottom of each compartment is formed of perforated metal. The topl and bottom l of this filter are also of perforated metal. M represents the filling, which is, preferably, of animal charcoal. Said filter occupies the lower part of the chamber J. The steam, as it is exhausted from the engine, passes through pipe N into the chamber I, and all the steam that remains uncondensed, vescapes through the dischargefpipe O. The feedwater from a reservoir, or other source, enters the chamber I, through a pipe, l?, (over the stean1-induction pipe,) and passes out through the pipe Q, augmented in quantity by the water resulting from the condensation ot' exhaust steam in the chamber I, and

the upwardly extendingl discharge-pipe O. The water frompipe Qis forced into the chamber H through a pipe, It, by a pump, (not shown.) The courses of the steam and water through the chamberI cross each other, so that the steam is condensed, and the water heated. From the chamber H the water passes up the pipes G, and through the filter L to the upper chamber J, and passes out of thev chamber J through the pipe S to the boiler. -At the top ofthe chamber J is a pipe, T, through which scum is .blown oif, the clear water, free from scum, owing out through the pipe S. Much the largest proportion of the earthy matter in the water settles to the bottom of the chamber Has the Water comes to apartialrest in .said cl1amber, and what remains in it is held back by the llter. The sediment is blown off through the pipe U. The water is drawn from the chamber I, when desired, by a pipe,V.

I claim as new and of 'my invention- 1. The compartments H I J, tubes or pipes I Gr, and lfilter L, combined and arranged, and

having pipe connections for operating sub-v stantially in the mannerdcscrihed.

2. The cast-metal ends A B, and cylindrical attachments C D, provided with tube-sheets c d, and forming the scum and sediment chambers, respectively, in combination with the metal cylinder K, forming an intermediate chamber, l, and tubes Gr, connecting the np- Y per and lower chambers or reseryoirs,sub stantially as set forth.

3. The combination ot' chamber J, filter L vin lower part of same, water-induotion pipes Glv beneath the filter, and outflow-water pipe in the lower part; of chamber J, above the filter, and .blow-off pipe T at the top of said chamber, all substantially as set forth, and for the'purpose described.

4. The condensing-chamber I, surrounding the watertubes G, and provided with steam- Q at bottom, nml stemn-outlet 0 at top, as

inlet'J N and Water-outlet wafer-inlet- P and set forth.
