IMPROVEMENT IN BOILER-CLEANERS.

Specification forming part of Letters Patent No. 194,723, dated August 2B, 1877; application filed June 30, 1877.

To all lwhom 'it may concern Be it known that I, EZEA RANsoM, of Flint, in the county of Genesee and State of Michigan, have invented a new and valuable lmprovement in Apparatus for Extracting Impurities from Water in Steamoilers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a part sectional side elevation of my apparatus for extracting impurities from water in steam-boilers, and Fig. 2 is a plan view of the same.

The nature of my invention consists in the construction and arrangement ofan apparatus for extracting impurities from water in steamboilers, the object being to take the scum from the surface of the water in that part of the boiler over the fire-box, and, by means of a pipe, carry it outside of the boiler through a filter and back into the rear part of the boiler through a pipe connecting the lter with the rear part ot' the boiler.

The annexed drawings, to which reference is made, fully illustrate my invention.

A represents a steam-boiler, with tubes or flues B B of any ordinary construction. Within the boiler A are two floats, C C, connected by a plate, C', and ou this plate are bolts a, a, upon which are placed two small bars or plates, b b, adjusted up and down on the bolts, and held at any height desired by suitable nuts ,or ordinary set-screws may be used for the same purpose.

The bars or plates b b are attached to two skimmers, D D, which are made in the form of bellows, and. their inner ends connected by a pipe, d. The skimmers being thus made adjustable they can be raised or lowered, so as to bring their mouths even with the surface of the water.

From the center of thepipe d a pipe, G, leads to and connects with a short pipe, G1, passing through the top og' the boiler. In this pipe G1 are three joints, e, e, and e1, which allow the floating skimmers to adjust themselves to the level of the water, rising or falling in the boiler by the working of the feed-pump; or, in`

locomotive-boilers, going around curves or up and down grades; or in marine-boilers subjected to the roll ofthe ship.

h is a rod, passing down through the lug i, to keep the lioating skimmer in the center of the boiler. H is a lever, connected to the inner end of the pipe G, and hung on a rod in the boiler, the other end of the lever being provided with a counterbalancing-weight, I, for the purpose of lifting a portion of the deadweight of theA oats, skimmers, joints, and pipes, so that the skimmers can be set lower and still be on the surface. This enables the skimmers to perform their ofce closer down to the tubes or lines.

The upper end of the pipe G1 is, by a pipe, G2, connected with a ilter, J, outside ot the boiler. This lilter is provided with interior partitions m m', arranged as shown, whereby the current of water is partially broken, the water rst passing up over the top of the partition lm., thence down the Vcenter of the filter, where the impurities, being heaviest, will settle, and the purified water passes up between the partition 'm' and the shell of the filter to the outlet-pipe G3, through which it passes back into the boiler.

The filter J is at the bottom provided with an outlet-pipe, K, which should have a stopcock to be opened when required, for drawing 0E all the sediment out of the lter.

The pipes G2 and Gr3 are also to be provided with stop-cocks, for the purpose of. stopping the circulation when required.

rlhe operation of the apparatus is as follows: The stop-cock in pipe G3 being closed and that in the pipe G2 opened, a current of hot water, with the impurities contained therein, with steam, will be forced` vup through the skimmers and pipes G G1 Gf2 into the filter J and thence into that portion of the pipe G3 between its stop-cock and the filter. The stopcock G3 is then opened, when the filtered water will be carried back into the rear part of the boiler, a partial vacuum being formed in the pipes G G1 Grz by the condensation of the steam therein and the coolingof the water, thus causing a continuous circulation of the water from the front to the rear part of the boiler, and a removal of the impurities.

Wha-tI claim as new, and desire to secure by Letters Patent, is-

1. The skimmers D D, adjustably connected to floats A, and by pipes connected With a tilter outside the boiler, for the purposes herein set forth.

2. The lever H, with Vcounterbalancing- Weight I, in combination With the iioats, skimmers, and pipes connected with the filter, as and for the purposes herein set forth. s

3. The joints e e e', formed in the pipe G, in combination with the skimmers and oats,

' substantially as and for the purposes herein set forth.

4. The combination of the floats, the skimmers, eounterbalancing-lever, jointed pipe, ilter, and connecting-pipes, al1 constructed and arranged to operate substantially as and for the purposes herein set forth.

1n testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

EZRA RANSOM.
