FEED-WATER HEATER AND FILTER.

SPECIFICATION forming part of Letters Patent No. 301,663. dated July 8, 1884:.

l Application filed February 6,1854. (No model.)

.To all whom it may concern,.-

Be it\ known that I, DAVID BOURGEOIS, a citizen of the United States of America, re# siding at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in Feed-Water Heaters and Filters, of which the following is a specifica-tion, reference being had therein to i the accompanying drawing. i

My invention relates to improvements in precipitators and filters, and is more especially designed as an improvement on the invention described in Letters Patent'No. 271,025,

granted to me on the 23d day of January, 1883.

Van opening formed in the side of the shell,and

at the point shown, a pipe, B,is inscrted,which extends to about the center ofthe precipitator, and is connected by suitable coupling to a vertical pipe, C. Pipe B communicates with any suitable pump or supply, and through it and p pipe C wateris fed to the preoipitator.

To the upper end of pipe C there is secured a horizontal pipe, a, `provided with a number of small openings, through which the water passes, said water being' thus introduced to theprecipitator insprays. Y

Secured to pipe C at points below pipe a are a series of shelves, Z1, all of different sizes, the smallest shelf being the first below pipe a, and each shelf thereafter being gradually increased in size. A pipe, D, which connects with the steam-drum of the boiler, is inserted through the side of the shell at a point slightly below the bottom shelf b.

By means of the construction and arrangement thus far described, the water sprays ejected through pipe a fall upon the severa-l shelves b, and by them are retarded until aeted upon by the steam entering through pipe D until they are raised to the temperature at which all mineral substances are separated therefrom andprecipitated to a chamber, E, hereinafter referred to. y

VA plate or disk, o, is secured to the inner face of the precipitatorshell, and at a point slightly below the pipe B, all of the space above said disk being the steam-space. Se cured to the inner face of the shell, and at a suitable point above the bottom thereof, is a perforated disk, d, the space between said disks c d being iilled with any suitable filtering material, IT, such as coke. Y

At or about the center of cach disk c d there is 'provided an opening, which are connected by a pipe, G, which passes through a disk, to be hereinafter referred to, and the iilteringchamber H, formed between said disks, and forms communication between the upper or steam space and the mud-chamber E, before referred to, and which is formed by the perforated disk d and the bottom of shell A. Chamber Eis provided with an outlet, o, closed by a suitable valve, and through which, at certain intervals, the impurities therein deposited are drawn off. A pipe, I, which connects with the boiler, is inserted through the shell into chamber H, and at a point near the top thereof, and through said pipe the water, after passing th rough the filtering material F, as will be described, is fed to the boiler.

At a suitable point below pipe I there may be provided in chamber H a perforated disk,

f, to prevent the coke from entering saidpipe.

Suitable man-holes, K K', may be provided, through which access may be gained to chambers H E and hand-holes L, for gaining access to the steam-space. As the heated and puried water falls from the lowest shelf b it passes through pipe G to chamber E, and thence, as indicated by arrows, up through the iiltering material, through pipe I, to the boiler, being during its passage thoroughly puriiied and raised to a proper temperature.

It will be understood that my improved precipitator and lter may be used in connection with heaters, or may be connected direct with the supply.

What I claim is- 1. In a precipitator provided with a steamspace, the combinati.on,with water and steam IOO supply pipes, of a series of shelves of different l supply pipes, of a series of shelves of different dimensions,` mounted upon the Water-supply dimensions, mounted on said Water-supply pipe and adapted to retard the water in its pipeand adaptedto retardthewater inits flow, 15 flow, as and for the purpose set forth. and a.' iilteringchumber situated below said 5 2. In a preoipitator provided With a steamsteam-space, as and for the purpose set forth. space, the combination, with water and steam In testimony whereof Iafxmy signature in supply pipes, of a series of shelves of different presence of two witnesses.

dimensions mounted upon the water-supply pipe, and a7 perforated pipe secured to the top DAVID BOURGEOIS 1o thereof', as and for the purpose set forth. Witnesses:
