FROM- SEA WATER. Patented July 3, 1860.

GEORGE S. G. SPENOE OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN APPARATUS FOR DISTILLING SEA-WATER.

To all whom-it may concern.-

Be it known that I, G. S. G. SPENGE, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Oonstruction of Apparatus for Obtaining Fresh Water from Sea-Water, and which is also capable of being applied to other similar purposes; and I hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and references, which make part of this specification.

The nature of the invention consists in the arrangement and combination of a boiler with a movable condensing apparatus and a funnelreceptacle within the chamber of the boiler for discharging the condensed distillate therefrom.

In the accompanying drawings and references, Figural shows a vertical section of the boiler, condenserand receptac1e;.Fig. 2, an elevation of the same apparatus with the stopcockfor discharging steam and air in the com mencement of the process; Fig. 3, a siphon shown'in section and of peculiar construction, to be filled by means of a blast of air through it. 7 Let A A represent the sides of the boiler; A, the bottom, which may be received into the usual opening'in thetop of a cooking-stove or range.

B is the funnel-receptacle,receiving thecondensed vapor from the under side of the condenser and conducting it-off by the dischargepipe 0.

0' represents th condensing-surface of the condenser to be filled with cold water to line f, or even higher.

D is a stop-cock for the discharge of air'and steam when the boiler is first put in operation,

and may be afterward closed.

E is a .depressionor groove on the outside of the flange FF, designed to receive the asvsending portion of pipe 0, which, as herein shown, rises on the inside and discharges its 7 contents at or near the middle of the height-of the boiler, but might equally well be so 'ar condensing apparatus. OF E, &c., is supplied .space.

Specification forming part of'Letters Patent No. 29,0] 5, dated J uly 3, 1860.

with suitablehandles, b b, and projecting flange F F, which rests on the shoulder a: w, and is made removable, as seen in the drawings. It is designed that the flange F F shall be parallel with and nearly in contact with the sides of the boiler, whether groove E be used or not. Re-

ceptacle B is made with a very shorttrunipetmouth to receivejthe drip from the inverted cone C, and should be barely large enough to receive the drip of condensed liquid with certainty from the point of the inverted cone, and since the flange F F comes nearly into contact with the sides of the boiler thearea of the funnel-mouth B need not be larger than that of a silver dollar,or thereabout. This proportion gives almost the entire surface of the condensing-bottom O to the direct action of the ascending currents of steam and produces greatly-increased rapidity of condensation.

In the arrangement of this apparatus it is desirable that it bemade comparatively broad and low to obtain an in creased condensing-surface, and to bring that surface 'as nearas may be to the surface of the boiling liquid without coming so near as to receive the spray and rupture of the bubbles produced from boiling. \Vhen this apparatus is used for obtaining fresh water from sea-water, a principal use designed by this invention, this intervening space will be regulated by practice, and will be governed by the strength of the fire,.the exposure of the boiler-bottom, 85c. Strongfire and nearness to the fire would requirea greater distance between the boiling-surface of 1 the liquid and the bottom of the condensing-surface, while low fire would require a diminished These involve skill and not invention. It is also-practicable to suspend a vessel under-the condensing-apex in place of the funnel-receptacle above named. The width of the bottom of theboiler is also part of the consideration of the distancebetween the'boiling and. condensing surface. The amount of water condensed will also depend upon. the amount of fire-surface exposed.

\Vhen the boiler is to be kept in constant action, as in the caboose of a ship at. sea, the usual supply-pipes for cold water and for discharging the heated water from the condenser are used and need not be described here. For temporary purposes, however, a siphon, G, of

peculiar form,is used to discharge the hot wathe mode of using the same, what I claim as ter from the condenser. It consists of a small new, and desire to secure byLetters'Patentflsbent tube, g'i, receivedend soldered. into a The arrangement of the receptacle B, in 5 larger tube, h k, as shown in Fig. 3, the mouth combination with the boiler A. and condenser is being slightly trumpet form.
