FEED-WATER HEATER AND PURlFlER.

SPECTPICATION forming part of Letters Patent No. 302,955, dated August 5, 1884.

Application filed February 23, 1884. {No model.)

ToaZZ whom it may concern.-

Be it known that I, Fonnvon Sronnn, a

' subject of the English'Government, (but have er and Purifier for Steam -Bilers, of which cupya perpendicular position.

the following is a specification, and that according to my knowledge and belief the same has not been in public use or on sale in the United States.

My invention relates to an improvement in feed-water heaters and purifiers, the object of the same being to provide a device of this character in which the water'filter will be adapted to operate in conjunction with water supplied from a suitable pump; and, further, to provide means by which the water will be immediately heated to high temperature by means of steam supplied from the boiler, and by the action of which the impuritcs of the water are precipitated before the water passes into the boiler. A further object is to provide a portable device of this character which may be readily and conveniently attached to boiler of ordinary construction; a further object being to provide a device of this charac;

ter with a swinging or regulable bracket, by means of which the same may be attached to a boiler either below or above the centerline of the boiler, and yet permit the same to oc- A further objct is to provide a device of this character which shall be simple and economical in construction, and durable and efficient in use; and with these ends in view my invent-ion consists in certain details of construction and combinations of parts, as will be more fullydescribed, and pointed out in the claims.

In the accompanying drawing, the figure shown is a vertical sectional view of my improvement.

A represents a cylindrical casing connecting the upper and lower chambers, B and (3, which are secured thereto in any desired man ner. Thelower chamber is centrally provided on its lower end with a screw-threaded opening, through which passes the feed-pipe E,

which is secured therein. The feed-pipe E is provided with a screw-threaded upper end,to

which is secured the cylindrical box or casing F, which is provided with screw threaded openings, into which are secured the tubes G, which are screw-threaded upon their lower ends. Thesaid tubes G may be of any desired number and size, according to the amount of work desired. The upper ends of the tubes are provided with the downwardly curved flanges H, as shown, for the purpose of allowing the water to flow therefrom in thin and varied streams. The upper ends of the said tubes G open into the steam space or chamber B. The said chamber Bis provided with the top I, which is secured thereto in any suit ablemanner. The spaces J are formed be tween the tubes G and the casing A, and open into the chambers B and G, the said space extending within a short distance of the bottom of the lower chamber, G, as shown. Thelowcr chamber, 0, is provided near its upper end with the water-passage K, which connects with the chamber L. To the chamber L is mova bly secured the filter K, which in this instance is provided with a suitable flange, O, which rests upon the shoulder}? of the chamber L. The filter K is made of strong wire-cloth of sufficient elasticity to lit closely around the inside of the chamber L. The filter is supplied with a coating of sponge upon its inner walls, the whole being re-cnforced by a quantity of charcoal, and secured in position by means of a perforated metallic cover, R. If desired, the filter maybe supplied with ahandle, S, for convenience in removing it when it is dcsi red to clean or renew its contents. This maybe accomplished by removing the cover T, which is secured over the chamber L in any desired manner. The chambers 13 and Larc'providcd with screw-threaded openings, into which are secured the ends of the steam-induction pipes U and V. These pipes are provided at any part of their length with suitable stop-cocks, for the purpose of regulating the flow of steam into the apparatus. The chamber L is provided above the shoulder P with a screw-threaded opening, into which is secured the watcr-eduction pipe Y,

. time by opening the cock AC which is inclined downwardly and connects with the 'boiler, and by means of which the same is supplied with water.

A suitable water-gage, Z, is secured in the position shown connecting with the spaces J for the purpose of determining at successive strokes of the pump whether or not thewater is passing freely to the boiler. The lower chamber, 0, is provided with the blow-off pipe and cook A.

For the purpose of providing an adjusting device to connect the feed-heater to the boiler,

,I provide the side frame, B, of the chamber 0 with an arm, 0, which is formed integral there with or secured thereto in any desired manner. The arm is provided with a hole through which passes the thumb-screw D. To the arm is pivotally secured an adjustable bracket, E, formed, as shown, and provided with the elongated slot F, by means of which the bracket may be caused to assume any desired position.

Having described the construction of my apparatus, its operation is as follows: The steam-pipes U and V are opened and the steam issues from the boiler and immediately fills all available space in the apparatus. The water is then forced into the tubes G, through the feed-pipe E, and, coming into contact with the live steam, is heated to a high temperature. The water ascends upward through the tubes, and, overflowing the same, runs over and into the spaces J, and, descending the same, runs out at the lower ends into the chamber 0, and filling which, it flows into the water-passage K, and through the chamber L into the filter K,and from thence into the induction-pipe Y, which leads to the boiler. The continuous action of the steam upon the water precipitates the matter, sediments, and other impurities, which fall through the spaces J into the chamber G, from whence it may be removed at any By the above means the boiler is supplied with water possessing an equal temperature to that already in the boiler, thus overcoming the danger of sudden contraction and expansion of the plates, and other probable dangers likely to result from the sudden introduction of cold or partially-heated water into the boiler.

It is evident that slight changes in the construction and relative arrangement of the several parts of my invention might be resorted to without departing from the spirit of myinvention, and hence I would have it understood that I do not confine myself to the exact construction shown and described, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.
