Letras Patent No. 88,484, dated lira/rch 3o, 1869.

IMPROVED'APPARATUS FOR HEATING-VAND SEPARATING- LIME FROM WAEER.

The Schedule referred to in these Letters Patent and making part of the same. o .p .r

To all whom 'it ma/y concern Be it known that we, SAMUEL F. JACKSON and JEF- FERsoN A. DAVIS, of Eureka, in the county of Woodford, and State of Illinois, have invented a new and valuable Improvement in a Spray-Heater and Lime- Extractor Combined; and do hereby declare that the following is f'full, clear, andexact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.-

the escape-pipe.

Letter C, an aperture in the bottom, near the front end of the heater. p

Letters a b c are perforated sheetiron shelves, of unequal lengths, arranged, one above another, and supported by wooden slats, f f f f f j, as represented in fig. 3 of drawings.

Letter D represents a pipe, inserted in the front end of the heater, for carrying steam into the heater.

E, an escape-pipe for the steam.

. Letters e e. e (see iig. 2) are wedges, for fastening the lid, or door of4 the heater.

Letters F F are slats, fastened to the under side `of the door, for the purpose of pressing down on the shelves, and securing them in their places.

Letter G (see g. 1) represents the door ofthe heater,

secured, on the backside, by strong hinges, g, (see fig. 3,) and, in the front, by wedges, e e e, in manner as set forth in fig. 1 of drawings.

Our device is operated as follows:

The impure water enters the heater by means of a suitable pipe inserted'in aperture B, (see figs. 1 and 2,) when it falls upon perforated shelf a; from thence to shelf b thence to shelf c; and thence to the bottom of the heater. Then, by means of a pipe inserted in aperture H, the purified water is conveyed away from the heater.

The heater can either be set on trestles, or hung on a frame-work, and the end from which the water leaves the heater is lowered, so that the water will all run out.

'lhe steam enters the heater' at the pipe in the front end of the heater, and the shelves in the heater are so arranged as to throw the steam equally under each shelf.

The steam passes through under the shelves, and goes out through the escape-pipe on top.

lhe water, falling through the small perforations in the shelves, becomes misty, and is rapidly heated by tbe steam, as it passes through the heater.

'lhe lime, or other salt, is deposited on these per- -forated shelves, and on the bottom of the heat-er.

The'shelves do not extend to the front, but a short opening isleft, so that, if the perforations in the shelves should become closed by the formation of lime-sediment, the water can run over the ends; and they do not extend quite to the back end, so as to enable the steam to pass up to and through the escape-pipe.

These shelves are made of sheet-iron, and are cleaned from the lime-sediment by removingr them from the heater, and rolling them up, when the sediment breaks into small pieces, and falls off.

v The heater-box is made of two-inch lumber.

The lid, or door, on top, is secured to the back side of the heater-box by three hinges.

Three iron bars, or straps, It k k, are screwed on to the top of the door, extending from the back to the front side, and secured, by slots and wedges, to corresponding bars secured tothe front side, perpendicularly,

extending from the bottom to the top of the front'side, as in manner set forth in figs.- l and 2 of accompanying drawings.

What we claim as our invention, and desire to secure by Letters Patent, is-

A spra Y-heater and lime-extractor, having perforatedv nesses.
