UNITED STATES PATENT OFFICE.
JOHN KELLER, OF ST. LOUIS, MISSOURI.
FEED-WATERHEATER.
SPECIFICATION forming part of Letters Patent No. 282,902, dated August 7, 1883. I
Application filed April 9,1883. (No model.)
To all whom it may concern.-
Be it known that I, JOHN KELLER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Feed-Water Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
The scope of my invention is set forth in the claims.
Figure l is an axial section at 1 1, Fig. 3. Fig. '2 is a side elevation of the lower portion of the apparatus with part of the outer shell broken away. Fig. 3 is a horizontal section at 3 3, Fig. 1.
outer cylindrical shell having a bottom, B, and top B 7 b O is an interior cylindrical shell or chamber suspended concentrically within the shell B, and having a bottom, O, and top 0 D are a number of tubes passing through holes in the top and bottom plates, 0 O, and expanded therein, so as to make tight joints between the tubes and the plates 0 G The top plate, B, has an aperture, B about equal in diameter to the perforate plate 0 and through this aperture the exhaust-steam from the steam-engine enters the upper ends of the tubes D and passes down the tubes to the lower part of the case B, where it impinges upon a deposit of water, E, occupying the lower part of the case-chamber B.
Under the chamber O is an annular jet-pipe, F, having numerous jet-holes at F, casting a spray of cold water upon the steam and cansing condensation of the same. The jet-pipe is fed by a cold-water supply-pipe, G, the water being forced through the pipe Gby an injector or pump, if required. Any uncondensed steam passes up the annularspace B betweenthe cases B and O, and finds exit through the eductionorifiee B.
H is a pipe, through which water escapes from the chamber B to supply the doctor, which forces the water through the pipe I into the lower part of the chamber O through which the pipes D pass. The water fills the chamber G as high as the opening of the eduction-pipe J, through which the water escapes from chamber 0 and goes to feed the boiler. This pipe J may descend in the annular space B so as to cause some increase in the heat of The surface'of the water E should be kept at about one level by means of a ball cock or other well-known or suitable means.
I claim herein as new and of my invention 1. The combination, in a feed-water heater, of exhaust-steam tubes descending through a water-chamber within a case containing water whose surface is beneath the lower ends of the said pipes, substantially as set forth. A is the base of the apparatus. B is an 2. The combination of outer shell, B, inner shell, 0, having tubes D, passing entirely through it, exhaust-passage at top of the inner shell, and jet-pipe F at the bottom of the inner shell, the exhaust entering the upperends of the tubes in a direct line therewith, and the uncondensed steam passing upward through the chamber formed between the inner and outer shells, as set forth.
3. The case B, with exhaust-steam openings B B, and containing water chamber or vessel 0, traversed by steam pipes or tubes D, discharging upon water-deposit E, and water.- pipes H, I, and J. communicating with the chambers B O substantially as and for the purpose set forth.
4. The combination, in a feed-water heater, of outer case, B, containing'a case, 0, placed concentrically therein, and of smaller diameter, containing water, and traversed by tubes D, and the induction and eduction exhaust-steam passages B B in communication, respectively, with the upper ends of the tubes D and the upper part of the annular space B substan:
'tially as set forth.
5. In a feed-water heater, the combination of outer shell, B, inner shell, 0, leaving chamber B between them, tubes D, passing entirely through the inner shell, exhaust-steam inlet B in line with the tops of the tubes, steameXit at top of the outer shell, pipe to supply water to the lower part of inner shell, discharge-pipe at the upper part of inner shell, and a mud-drum connected with the bottom of the inner shell by a pipe, K, as set forth.
Witnesses: JOHN KELLER.
