FEED-WATER H EATER.
SPECIFICATION forming part of Letters Patent No. 332,824, dated December 22, 1885.
Application filed October 1, 1885.
.To all whom it may concern:
for heating and purifying feed-water to boilers; and my invention consists of a boiler-iron box at the rear of the boiler, a second box or casing upon the first box and containing return-flues communicating with the pipe from the pump, said box or casing receiving the exhaust-steam, a globe connected with one end of the first box and with a pipe from the dues of the second box, a globe connected with the other end of the first box and with the pipe to the boiler, a cup or disk in the first globe to receive the feed-water, and a valved outletpipe from said cup, a check-valve in the second globe, a perforated casing around said valve, and a screen-cylinder around the casing, a discharge-pipe from the globe, and other details of construction, all of which I shall hereinafter fully describe.
The object of my invention is to provide a simple and effective device which is adapted not only to heat thefeed-water, but at the same time to purify it, and which can be easily cleansed.
Referring to the accompanying drawings, Figure l is an end elevation of my device.
. Fig. 2 is a longitudinal vertical section.
A is a portion of a boiler, of which a are the tubes, and a the rear tube-sheet. Instead of the rear plate of the boiler, I have the boiler-iron box B, resting on the brick-work, and adaptv -ed to be heated directly by the flames as they return through the tubes. I In the rear of the boiler-iron box are man-holes b. On top of the box B is a second box or casing, X,' containing return-pipes ac, communicating with a 5 is a globe, C, in the top of which is let the pipe 0 from the pipes 4v. Within the globe is Serial No. 178,765. (No model.)
a cup or dish, D, from the bottom of which a pipe, (1, extends and passes out through the globe to the ash-pan, a valve, d, being let into said pipe. The pipe 0 projects downwardly into the globe, and has screwed upon its end, just above the cup or dish D, a conical sleeve or thimble, W. The lower end of the pipe 0 is closed,but perforations c are madein its sides, through which the water escapes. A conical screen or sieve, V, is slipped over the rim of the cup D,and embraces with its top the pipe 0. On the other end of box X is a globe, E, within which is a perforated casing, F, the stem f of which communicates with the box B. In this casing is seated an upwardly-moving check-valve, G. Supported on small lugs 0 within the globe E is a cylindrical screen or sieve, R, which may be made of wire-cloth or perforated metal, such as zinc. In the top of the wire-cloth cylinder is an upwardlyopening check or safety valve, 9', held to its seat by a spring, r.
H is a pipe which leads from the top of the globe to the boiler.
I is a pipe leading out of the globe near its base, and provided with avalve or cook, z.
The operation of my device is as follows: The feed-water is forced by the pump through pipe 00 and through the flues a: of box X, in which its temperature is raised by the ex haust-steam. Thence it passes through the pipe 0, escaping through the perforations at its lower end, and striking against the conical thimble or sleeve W, from which it drops down into the cup or dish D. The valve 01 of the outlet-pipe d of said cup or dish being closed, the water overflows through the screen V. A great portion of the impurities are left in the sides of the cup and in its outlet-pipe. The presence of the sleeve or thimble IV, which receives the first impact of the water, prevents undue agitation of the water in the cup, and thus induces the water to part with its impurities, a result which is further assisted by the screen V. The water thus purified passes down through the globe into the boileriron box B, in which it is fully heated. It is thence forced up through the stem f, past the valve G, into the casing F, through the perforations of which it passes outwardly through the screen B into the globe E. In thus passing through the parts described whatever impurities may be still in the water are separated and deposited as sediment in the base of the globe. The pure water passes through pipe H to the boiler. The object of the valve r in the top of the screen Bis to relieve said screen if it should become clogged. \Vhen a sufiicient quantity of sediment has collected in the cup D of the globe O, the cock d of its discharge-pipe d is opened, and the impurities are blown out into the ash-pan by the incoming water; and when the impurities have accumulated in the globcEthe pump is stopped, the cock 1' of the discharge-pipe I is opened, and the whole pressure of the water in the boiler is thrown back into the globe, whereby its impurities are washed out. The box B is cleansed through the man-holes 1).
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
